Emergency Precautions

Tires

When replacing tires, be sure to equip all four tires with the same size, type, tread patterns, brand and load-carrying capacity.

Do not use wheels and tires with different size and type from the ones originally installed on your vehicle. Do not use mismatched wheels and tires that may cause sensing issues with the AWD system. It can affect the safety and performance of your vehicle, which could lead to steering failure or rollover causing serious injury.

Never start or run the vehicle while an AWD vehicle is raised on a jack. The vehicle can slip or roll off of a jack causing serious injury or death to you or those nearby.

Towing

AWD vehicles must be towed with a wheel lift and dollies or flatbed equipment with all the wheels off the ground. For more details, refer to "Towing" section in chapter 8.

Vehicle inspection

  • If the vehicle needs to be operated on a vehicle lift do not attempt to stop any of the four wheels from turning. This could damage the AWD system.

  • Never engage the parking brake while running the vehicle on a car lift. This may damage the AWD system.

Dynamometer testing

An AWD vehicle must be tested on a special four wheel chassis dynamometer.
