IN CASE OF EMERGENCY 347
(Continued)
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand, or
snow, it can often be moved using a rocking
motion. Turn the steering wheel right and left to
clear the area around the front wheels. Then shift
back and forth between DRIVE (D) and REVERSE
(R), while gently pressing the accelerator. Use the
least amount of accelerator pedal pressure that
will maintain the rocking motion, without spinning
the wheels or racing the engine.
NOTE:
For trucks equipped with an 8–speed transmis-
sion, shifts between DRIVE and REVERSE can
on
l
y be achieved at wheel speeds of 5 mph
(8
km/h) or less. Whenever the transmission
r
e
mains in NEUTRAL (N) for more than two
seconds, you must press the brake pedal to
engage DRIVE or REVERSE.
Push the ESC OFF button to place the Electronic
Stability Control (ESC) system in “Partial OFF”
mode, before rocking the vehicle
Ú page 274.
Once the vehicle has been freed, push the ESC
O
F
F button again to restore “ESC On” mode.
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,
di
sabled vehicles may also be towed as described
on
Ú page 222.
NOTE:
Vehicles equipped with the Air Suspension System
Ú page 157 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.
CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the temperature gauge reads
HOT (H), pull over and stop the vehicle. Idle the
vehicle with the air conditioner turned off until
the pointer drops back into the normal range. If
the pointer remains on HOT (H), and you hear
continuous chimes, turn the engine off
immediately and call for service.
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 sec-
onds continuously without stopping when you
a
re 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 transmis
-
sion failure during prolonged efforts to free a
s
tuck 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 occurring).
CAUTION!
