Tires, Wheels and Loading
All Wheel Drive (AWD) vehicles:
Tow your All Wheel Drive vehicle with all four wheels on the ground or
with all four wheels off the ground using a vehicle transport trailer. Do
not tow your All Wheel Drive vehicle with the front wheels off
the ground (by using a tow dolly) and the rear wheels on the
ground. This will cause damage to your AWD system. If you are using a
vehicle transport trailer, follow the instruction specified by the
equipment provider.
Note: If you tow your vehicle with all four wheels on the ground, follow
these instructions:
• Tow only in the forward direction.
• Release the parking brake.
• Place the transmission shift lever in (N) Neutral.
• Place the ignition in the accessory position (refer to Starting in the
Driving chapter).
• Do not exceed 65 mph (105 km/h)
• Start the engine and allow it to run for five minutes at the beginning
of each day and at each fuel stop.
