WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2007 GMC Yukon XL, 2007 GMC Yukon, 2007 Chevrolet Tahoe, 2007 Chevrolet Suburban, and 2007 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
One or more of the following guidelines may apply when performing specific required tests in the work stall:
- When a test requires spinning the drive wheels with the vehicle jacked up, adhere to the following precautions:
- Do not exceed 56 km/h (35 mph) when spinning one drive wheel with the other drive wheel stopped. This limit is necessary because the speedometer indicates only one-half the actual vehicle speed under these conditions. Personal injury may result from excessive wheel spinning.
- If all of the drive wheels are spinning at the same speed, do not exceed 112 km/h (70 mph). Personal injury may result from excessive wheel spinning.
- All persons should stay clear of the rotating components and the balance weight areas in order to avoid possible personal injury.
- When running an engine in the repair stall for an extended period of time, use care not to overheat the engine and the transmission.
- When a test requires jacking up the vehicle and running with the wheels and brake rotors removed, adhere to the following precautions:
- Support the suspension at normal ride height.
- Do not apply the brake with the brake rotors removed.
- Do not place the transmission in PARK with the drive axles spinning.
- Turn Off the ignition in order to stop the powertrain components from spinning.
