To keep passengers entertained and con-nected, the Cruze features an intuitive next-generation MyLink infotainment system replete with a 7-inch diagonal color touch display, Apple CarPlay and Android Auto compatibility, and available 4G LTE Wi-Fi. Wireless charging also is avail-able. The charging pocket is located on the center console. The phone should be placed in the pocket with the screen facing the rear of the vehicle.

“Tech savvy” also applies to the sedan’s many safety features, such as available Side Blind Zone Alert with Lane Change Alert, Lane Keep Assist with Lane Departure Warning, and Forward Collision Alert, which utilize advanced radar and camera-based technologies to help drivers avoid a crash.

Vehicle Lifting

When servicing the Cruze’s underbody, the use of a Low Profile Lift Arms System may be required to avoid unwanted contact with the vehicle’s body and structure, depending on the lift equipment used.

Front Lift Pads: When lifting the vehicle with a frame-contact lift, place the front lift pads on the rocker outer panel weld flange.

Rear Lift Pads: Place the rear pads on the rocker outer panel weld flange.

If raising the vehicle from the front or rear with a service jack, use the same frame contact locations as for the front and rear lift pads.

For additional information about the new 2016 Cruze, refer to Bulletin #16-NA-053.

The aluminum cylinder block and head with an integrated DOHC cylinder head/exhaust manifold help to reduce engine weight. While the variable-flow oiling system with a 2-stage variable displacement oil pump add to engine’s fuel efficiency.

The turbocharger con-sists of a turbine and a compressor on a com-mon shaft. The shaft bearing is constructed for higher rotation speed and lubricated by engine oil. The turbo-charger is water cooled for improved durability.

On models equipped with the automatic transmission, the Stop/Start system may turn OFF the engine temporarily when the brake is applied and the vehicle comes to a complete stop. The audio system, climate controls and other accessories continue to oper-ate. Upon releasing the brake pedal or applying the accelerator, the engine restarts. The engine may continue running or restart when the vehicle is stopped if certain operating conditions are not met.

TIP: Some customers may notice a clicking noise or feel a detent when depressing the accelerator pedal all the way down. This is normal operation. There is a wide open throttle detent switch that provides the driver with feedback when full accelerator pedal travel has been reached.

Depending on model, the Cruze features the M32 6-speed manual transmission (RPO MF3) or the Hydra-matic 6T35 6-speed automatic transmission (RPO MNU). The new 6T35 transmission features Gen 3 upgrades implemented to enhance efficiency. The binary vane-type pump, for example, has been moved off-axis, which allows better sealing of the torque converter, reducing pump flow demands to enhance fuel economy.

The M32 manual transmission uses a premium three-shaft de-sign with synchronizers for all gears, including Reverse. First and second gears feature triple-cone synchronizers and double-cone synchronizers are used on third and fourth gears.

Every Cruze comes equipped with four-wheel disc antilock brakes as well as Duralife rotors that enhance corrosion resistance. Rack-mounted electric power steering is standard on all models.

New Technology

The new Cruze features available keyless access and pushbut-ton start. With the Remote Keyless Entry transmitter (key fob) within 3 feet (0.9 m) of the door or the trunk, press the button on the door handle to open the door or press the touchpad to open the trunk.

The key fob must be in the vehicle to start the engine. With the transmission in Park or Neutral, press the brake pedal (and clutch pedal, if equipped) and then press the ENGINE START/STOP button. The button indicator will be green when the engine starts. The button indicator will be amber when in accessory mode.

The only engine available is the all-new 1.4L turbocharged four cylinder engine.

The Cruze features a number of new infotainment and technology features.

The infotainment system supports Apple CarPlay and Android Auto.

Using a frame-contact lift, place the lift pads on the rocker outer panel weld flanges.

Air Filter Box Seal LeakOn some 2014-2016 Corvette, Silverado, Sierra; 2015-2016 Escalade models, Yukon models; and 2016 CTS and Camaro equipped with a V8 engine (RPOs LT1, LT4, L83, L86, LV1, LV3), the MIL may be il-luminated and DTCs P0420 (Catalyst System Low Ef-ficiency) and P0430 (Catalyst System Low Efficiency Bank 2) may be set. These conditions may be caused by excessive dirt/debris entering the air filter box and bypass-ing the seal of the air filter, causing damage to the H02 sensor element and blocking the catalytic converter.

Do not replace any parts for these condi-tions until the air fil-ter housing has been validated to be completely sealed.

Inspect the air housing cover for any missing tabs or fasteners. Also re-move the air filter housing cover and inspect the seal around the filter as well as the air filter sealing surface for signs of not con-tacting the air filter seal.

In addition, look for dirt/debris in the air filter housing cover bypassing the air filter.

If dirt/debris is bypassing the air filter due to a faulty seal, replace the air filter. If the air filter housing is not prop-erly sealing, refer to the appropriate Service Information for additional diag-nostic procedures.

Using an Insulation MultimeterSimilar to typical 12V vehicle systems, loss of isolation on the high voltage system of the Volt, ELR and Spark EV can be as simple as a direct conductor-to-chassis short. However, unlike 12V systems, the potential within high voltage systems means that insulation break-down is also a cause for loss of isolation. Insulation breakdown typically occurs only when high voltages and/or current is present.

An Insulation Multimeter (EL-50772) must be used to test the isolation capability of high voltage components and circuits. An insulation breakdown cannot be diagnosed with a typical digital multimeter (DMM) because high voltage is not used by the DMM when mea-suring resistance. An Insulation Multimeter uses its own built-in high voltage.

TIP: Always perform the high voltage disable procedure as published in the appropri-ate GM Service Information before servicing high voltage components and wiring and always wear the proper personal protective equipment.

Diagnosis with an Insulation Multimeter

The EL-50772 Insulation Multimeter tests the isolation capability of high voltage components and circuits. For correct test results, the functions of the Insulation Multimeter must be used properly.

Plug into the correct ports – It is critical that the correct ports (1, 2) are used for in-sulation testing. This is easy to get wrong, especially if the EL-50772 is used for standard DMM testing too. Do not use ports 3 and 4 for insulation testing. Also, if port 1 and port 4 are mistakenly used, continuity testing will still function, but the insulation test will always appear to pass.

Always test at the 500V range – With the test leads not connected to anything, press and hold the insulation test button to know how your meter displays an infinite mea-surement. The EL-50772 will display 550M Ω when measuring an open circuit while set to the 500V range

See how your meter displays continuity – With the test leads connected together, press and hold the insulation test button. The EL-50772 will display 0.0 Ω.

A good ground reference is needed – When possible, use an alligator clamp to attach the ground lead. Typically, the reference point will be to the vehicle chassis, except cable testing, which requires connection to the cable shield termination at the connector and not to the chassis.

Verify the ground connection – Prior to every test measurement, verify the ground connection at a suitable ground location near the test point. The EL-50772 should display 0.0 Ω, indicating continuity.

Large capacitance or inductance testing – When testing components with large capacitance or inductance, such as certain modules and larger motor stators, it may be necessary to hold the insulation test button for a few seconds until the maximum resis-tance value is displayed.

More Information

For more information about loss of isolation testing, U.S. dealerships can check out the March 2015 edition of the Emerging Issues seminar (10215.03D). It includes a video demonstration using an Insulation Multimeter.

The EL-50772 Insulation Multimeter (Fluke 1857) is available through GM Dealer Equipment. Equivalent tools also are available from other sources.

OnStar Advanced Diagnostics UpdateFor 2016, OnStar is expanding vehicle availability of its Advanced Diagnostics and Proactive Alerts services.

Diagnostic Alerts

Diagnostic Alerts help keep customers (who are enrolled in the ser-vice) informed of key vehicle systems, such as the engine, transmis-sion and ABS, with a status report available in real-time by email or text. The service is available on most 2015 and 2016 GM models.

The alerts are generated by an onboard diagnostic/sens-ing system that can be ana-lyzed using the appropriate Service Information.

Diagnostic Alerts include:

• Real-time maintenance and diagnostics that supple-ment a customer’s monthly Diagnostics Report

• Alert types that may cover oil life, flat tire, bulb out-ages, odometer-based maintenance, diesel ex-haust fluid (if equipped), Diagnostic Trouble Codes (DTC) and critically low battery charge.

• Various methods of notify-ing customers, including email, text message and Dealer Maintenance No-tification (DMN) —based on a customer’s prefer-ence when enrolling in the Advanced Diagnostics service.

Any DTCs that would have trigged an alert would also have been accompanied by the illumination of a Malfunc-tion Indicator Lamp on the instrument cluster, with the exception of an exterior bulb outage.

New Diagnostic Alerts

There are three new Diag nostic Alerts — Low Oil Maintenance (if less than or equal to 5%), Diesel Exhaust Fluid (75 miles or 120 km until empty) and Bulb Outage (1 per filament bulb outage). These alerts are sent to customers in their monthly Diagnostics Re-ports and are also sent to dealerships as part of their DMN leads.

DTCs Set during Service

With Diagnostic Alerts notifying customers of DTCs, they may receive alerts from their vehicle when it is being serviced if a DTC is set during repairs. Disconnecting components or electrical con-

nectors as required during some service procedures may set a DTC. Customers should be advised to disregard real-time alerts that are sent while their vehicle is being serviced.

Proactive Alerts

Proactive Alerts give customers peace of mind knowing that their vehicle’s key starting and fuel system components will not degrade without their knowledge, with notifications provided before a prob-lem occurs. The alerts are designed to help predict specific types of issues based on information collected from the vehicle. (Not all issues will produce alerts.)

Currently offered on V6-equipped 2015-2016 Equinox and Terrain models and the 2016 Corvette, Proactive Alerts will soon become available on 2016 Silverado, Suburban, Tahoe, Sierra, Yukon models and Escalade models.

TIP: Customers must at least have the OnStar Basic Plan to enroll in the service.

Proactive Alerts monitor the performance of the:

• Engine cranking system (battery and starter motor performance)

• Fuel delivery system (in-tank fuel pump module and fuel pressure sensor performance)

Notifications before a Failure

When a covered component is detected as having degraded per-formance, an alert is generated. This is designed to happen before customers experience an issue with the vehicle. Some Proactive Alert messages may be generated without customers noticing any symptoms.

Customers will be notified in real-time via email and/or text message. An in-vehicle audio alert over the infotainment system also may be provided.

Unlike Diagnostic Alerts, Proactive Alerts are not generated by the vehicle’s onboard diagnostics system. While the data is collected from that system, it is analyzed off-board.

Currently, no associated DTCs are stored on the vehicle. Diagnosis of these alerts are covered under Bulletin #PI1250 in the Service Information.

One of the covered components is the 12-volt starting battery. Because these alerts can be triggered before the vehicle exhibits symptoms, the Proactive Alert battery replace labor operation does not require the warranty code that’s generated by the EL-50313 (GR8). Conse-quently, it’s important that dealerships follow the bulletin and use the appropriate labor operations.

For more information on Proactive Alerts, including a list of dealership FAQs, refer to the Advanced Diagnostics course (GCF00.115-0D/OnStar-Advanced Diagnostics) available on the GM Center of Learning at www.centerlearning.com
