2. Put the vehicle in PARK (P).
3. Set the parking brake and then remove the key.
4. Clamp the steering wheel in a straight-ahead
position with a clamping device designed for towing.
5. Release the parking brake.
If you have an all-wheel-drive vehicle, it cannot be
towed with any of its wheels on the ground. It can be
towed with car carrier equipment.

four wheels on the ground, or even with only two of
its wheels on the ground, will damage drivetrain
components. Don’t tow an all-wheel-drive vehicle if
any of its wheels will be on the ground.
