IN CASE OF EMERGENCY 405
(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 and REVERSE,
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 transmission, shiftsbetween DRIVE and REVERSE can only be achieved at
wheel speeds of 5 mph (8 km/h) or less. Whenever the
transmission remains in NEUTRAL for more than two
seconds, you must press the brake pedal to engage DRIVE
or REVERSE.
• Push the "ESC Off" switch, to place the Electronic Stability Control (ESC) system in "Partial Off" mode, before rocking
the vehicle. Refer to “Electronic Brake Control” in “Safety”
for further information. Once the vehicle has been freed,
push the "ESC Off" switch again to restore "ESC On" mode.
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 trans -
mission 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.

406 IN CASE OF EMERGENCY
TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled
vehicle using a commercial towing service. If the transmis-
sion and drivetrain are operable, disabled vehicles may also
be towed as described under “Recreational Towing” in the
“Starting And Operating” section.
• 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).

SERVICING AND MAINTENANCE 433
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe and
abnormal catalyst overheating. If this occurs, stop the
vehicle, turn off the engine and allow it to cool. Service,
including a tune-up to manufacturer's specifications, should
be obtained immediately.
To minimize the possibility of catalytic converter damage:
• Do not interrupt the ignition when the transmission is ingear and the vehicle is in motion.
• Do not try to start the vehicle by pushing or towing the vehicle.
• Do not idle the engine with any ignition components disconnected or removed, such as when diagnostic testing,
or for prolonged periods during very rough idle or
malfunctioning operating conditions.Cooling System
WARNING!
• You or others can be badly burned by hot engine coolant (antifreeze) or steam from your radiator. If you
see or hear steam coming from under the hood, do not
open the hood until the radiator has had time to cool.
Never open a cooling system pressure cap when the
radiator or coolant bottle is hot.
• Keep hands, tools, clothing, and jewelry away from the radiator cooling fan when the hood is raised. The fan
starts automatically and may start at any time, whether
the engine is running or not.
• When working near the radiator cooling fan, discon -
nect the fan motor lead or turn the ignition to the OFF
mode. The fan is temperature controlled and can start at
any time the ignition is in the ON mode.

Tires — General Information
Tire Pressure
Proper tire inflation pressure is essential to the safe and satis-
factory operation of your vehicle. Four primary areas are
affected by improper tire pressure:
• Safety
• Fuel Economy
• Tread Wear
• Ride Comfort and Vehicle Stability
Safety
Both under-inflation and over-inflation affect the stability of
the vehicle and can produce a feeling of sluggish response or
over responsiveness in the steering.
NOTE:
• Unequal tire pressures from side to side may cause erraticand unpredictable steering response.
• Unequal tire pressure from side to side may cause the vehicle to drift left or right.
WARNING!
• Improperly inflated tires are dangerous and can cause collisions.
• Underinflation increases tire flexing and can result in overheating and tire failure.
• Overinflation reduces a tire's ability to cushion shock. Objects on the road and chuckholes can cause damage
that result in tire failure.
• Overinflated or underinflated tires can affect vehiclehandling and can fail suddenly, resulting in loss of
vehicle control.
• Unequal tire pressures can cause steering problems. You could lose control of your vehicle.
• Unequal tire pressures from one side of the vehicle to the other can cause the vehicle to drift to the right or
left.
• Always drive with each tire inflated to the recom -
mended cold tire inflation pressure.
