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, shifts
between 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. 6

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). CAUTION! (Continued)

IN CASE OF EMERGENCY 407
Proper towing or lifting equipment is required to prevent
damage to your vehicle. Use only tow bars and other equip -
ment designed for this purpose, following equipment manu -
facturer’s instructions. Use of safety chains is mandatory.
Attach a tow bar or other towing device to main structural
members of the vehicle, not to bumpers or associated
brackets. State and local laws regarding vehicles under tow
must be observed.
If you must use the accessories (wipers, defrosters, etc.)
while being towed, the ignition must be in the ON/RUN
mode, not the ACC mode.
If the key fob is unavailable or the vehicle's battery is
discharged, refer to “Manual Park Release” or “Gear Selector
Override” in this section for instructions on shifting the auto -
matic transmission out of PARK for towing. Two-Wheel Drive Models
The manufacturer recommends towing your vehicle with all
four wheels OFF the ground using a flatbed.
If flatbed equipment is not available, and the transmission is
operable, the vehicle may be towed (with the rear wheels on
the ground) under the following conditions:
• The transmission must be in NEUTRAL. Refer to “Manual
Park Release” in this section for instructions on shifting the
8–speed transmission to NEUTRAL when the engine is off.
• The towing speed must not exceed 30 mph (48 km/h).
• The towing distance must not exceed 15 miles (24 km) for
6–speed transmission, or 30 miles (48 km) for 8–speed
transmission.
If the transmission is not operable, or the vehicle must be
towed faster than 30 mph (48 km/h) or farther than 15 miles
(24 km) for 6–speed transmission, or 30 miles (48 km) for
8–speed transmission, tow with the rear wheels OFF the
ground. Acceptable methods are to tow the vehicle on a
flatbed, or with the front wheels raised and the rear wheels
on a towing dolly, or (when using a suitable steering wheel
stabilizer to hold the front wheels in the straight position)
with rear wheels raised and the front wheels on the ground.CAUTION!
• Do not use sling type equipment when towing. Vehicle
damage may occur.
• When securing the vehicle to a flat bed truck, do not
attach to front or rear suspension components. Damage
to your vehicle may result from improper towing. 6

408 IN CASE OF EMERGENCY
Four-Wheel Drive Models
The manufacturer recommends towing with all wheels OFF
the ground. Acceptable methods are to tow the vehicle on a
flatbed or with one end of vehicle raised and the opposite
end on a towing dolly.
If flatbed equipment is not available, and the transfer case is
operable, the vehicle may be towed (in the forward direction,
with ALL wheels on the ground), IF the transfer case is in
NEUTRAL and the transmission is in PARK (P). Refer to
“Recreational Towing” in “Starting And Operating” for
further information and detailed instructions. Emergency Tow Hooks — If Equipped
Your vehicle may be equipped with emergency tow hooks.
NOTE:
For off-road recovery, it is recommended to use both of the
front tow hooks to minimize the risk of damage to the
vehicle.CAUTION!
Towing this vehicle in violation of the above
requirements can cause severe engine and/or
transmission damage. Damage from improper towing is
not covered under the New Vehicle Limited Warranty. CAUTION!
• Front or rear wheel lifts must not be used (if the
remaining wheels are on the ground). Internal damage
to the transmission or transfer case will occur if a front
or rear wheel lift is used when towing.
• Towing this vehicle in violation of the above require -
ments can cause severe transmission and/or transfer
case damage. Damage from improper towing is not
covered under the New Vehicle Limited Warranty.

SERVICING AND MAINTENANCESCHEDULED SERVICING
Your vehicle is equipped with an automatic oil change indicator
system. The oil change indicator system will remind you that it
is time to take your vehicle in for scheduled maintenance.
Based on engine operation conditions, the oil change indi -
cator message will illuminate. This means that service is
required for your vehicle. Operating conditions such as
frequent short-trips, trailer tow, extremely hot or cold
ambient temperatures, and E85 fuel usage will influence
when the “Oil Change Required” message is displayed.
Severe Operating Conditions can cause the change oil
message to illuminate as early as 3,500 miles (5,600 km) since
last reset. Have your vehicle serviced as soon as possible,
within the next 500 miles (805 km).
Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a sched -
uled oil change is performed by someone other than your autho -
rized dealer, the message can be reset by referring to the steps
described under “Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” for further information. Gasoline Engines:
Under no circumstances should oil change intervals exceed
8,000 miles (13,000 km), twelve months or 350 hours of
engine run time, whichever comes first. The 350 hours of
engine run or idle time is generally only a concern for fleet
customers.
Severe Duty:
Change Engine Oil at 4,000 miles (6,500 km) or 350 hours of
engine run time if the vehicle is operated in a dusty and off
road environment or is operated predominately at idle or
very low engine RPM’s. This type of vehicle use is consid -
ered Severe Duty.

SERVICING AND MAINTENANCE 411
Once A Month Or Before A Long Trip:
• Check engine oil level.
• Check windshield washer fluid level.
• Check the tire inflation pressures and look for unusual
wear or damage. Rotate at the first sign of irregular wear.
• Check the fluid levels of the coolant reservoir, brake
master cylinder, power steering and automatic transmis -
sion (six-speed only), and fill as needed.
• Check function of all interior and exterior lights. Maintenance Plan
Required Maintenance
Refer to the maintenance plan on the following pages for
required maintenance.
