478 IN CASE OF EMERGENCY
TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled
vehicle using a commercial towing service.
If the transmission and drivetrain are operable, disabled
vehicles may also be towed as described under “Recreational
Towing (Behind Motorhome, Etc.)” in the “Starting And
Operating” section.
NOTE:
Vehicles equipped with the Active-Level Four Corner Air
Suspension System must be placed in Transport mode,
before tying them down (from the body) on a trailer or
flatbed truck. If the vehicle cannot be placed in Transport
mode (for example, engine will not run), tie-downs must be
fastened to the axles (not to the body). Failure to follow these
instructions may cause fault codes to be set and/or cause loss
of proper tie-down tension.
Refer to "Active-Level Four Corner Air Suspension System
— If Equipped" in "Starting And Operating" for more infor-
mation.
WARNING!
Fast spinning tires can be dangerous. Forces generated by
excessive wheel speeds may cause damage, or even failure, of
the axle and tires. A tire could explode and injure someone.
Do not spin your vehicle's wheels faster than 30 mph (48 km/ h) or for longer than 30 seconds continuously without
stopping when you are stuck and do not let anyone near a
spinning wheel, no matter what the speed.
CAUTION!
• Racing the engine or spinning the wheels may lead to transmission overheating and failure. Allow the engine to
idle with the transmission in NEUTRAL for at least one
minute after every five rocking-motion cycles. This will
minimize overheating and reduce the risk of transmission
failure during prolonged efforts to free a stuck vehicle.
• When “rocking” a stuck vehicle by shifting between DRIVE and REVERSE, do not spin the wheels faster than
15 mph (24 km/h), or drivetrain damage may result.
• Revving the engine or spinning the wheels too fast may lead to transmission overheating and failure. It can also
damage the tires. Do not spin the wheels above 30 mph
(48 km/h) while in gear (no transmission shifting occur-
ring).
