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 (with automatic transmission) or 2nd gear
and REVERSE (with manual transmission), while gently
pressing the accelerator. Use the least amount of accel-
erator pedal pressure that will maintain the rocking
motion, without spinning the wheels or racing the en-
gine.
CAUTION!Racing the engine or spinning the wheels may lead to
transmission overheating and failure. Allow the en-
gine to idle with the transmission in NEUTRAL for at
least one minute after every five rocking-motion (Continued) CAUTION! (Continued)cycles. This will minimize overheating and reduce
the risk of clutch or transmission failure during
prolonged efforts to free a stuck vehicle.
NOTE: 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 “Starting And Operating” for further infor-
mation. Once the vehicle has been freed, push the  ESC
Off  switch again to restore  ESC On  mode.
CAUTION!• When “rocking” a stuck vehicle by shifting be-
tween DRIVE/2nd gear and REVERSE, do not spin
the wheels faster than 15 mph (24 km/h), or drive-
train damage may result. (Continued) 6WHAT TO DO IN EMERGENCIES 553

Proper towing or lifting equipment is required to prevent
damage to your vehicle. Use only tow bars and other
equipment designed for this purpose, following equip-
ment manufacturer ’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
position, not the ACC position.
If the Key Fob is unavailable or the vehicle’s battery is
discharged, refer to “Gear Selector Override” in this
section for instructions on shifting the automatic trans-
mission out of PARK for towing. 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.
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 transmis-
sion is operable, the vehicle may be towed (with the rear
wheels on the ground) under the following conditions:
• The transmission must be in NEUTRAL.
• The towing speed must not exceed 30 mph (48 km/h). 6WHAT TO DO IN EMERGENCIES 557

• The towing distance must not exceed 15 miles (24 km).
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), 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!Towing this vehicle in violation of the above require-
ments can cause severe engine and/or transmission
damage. Damage from improper towing is not cov-
ered under the New Vehicle Limited Warranty. 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 (N) and the transmis-
sion is in PARK (for automatic transmissions) or in gear
(NOT in NEUTRAL, for manual transmissions). Refer to
“Recreational Towing” in “Starting And Operating” for
further information and detailed instructions.558 WHAT TO DO IN EMERGENCIES

ONBOARD DIAGNOSTIC SYSTEM (OBD II)
Your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. This system monitors
the performance of the emissions, engine, and automatic
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions well within current government regulations.
If any of these systems require service, the OBD II system
will turn on the “Malfunction Indicator Light (MIL).” It
will also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be drivable and not
need towing, see your authorized dealer for service as
soon as possible. CAUTION!• Prolonged driving with the MIL on could cause
further damage to the emission control system. It
could also affect fuel economy and driveability.
The vehicle must be serviced before any emissions
tests can be performed.
• If the MIL is flashing, while the engine is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
Onboard Diagnostic System (OBD II)
Cybersecurity
Your vehicle is required to have an Onboard Diagnostic
system (OBD II) and a connection port to allow access to
information related to the performance of your emissions
controls. Authorized service technicians may need to564 MAINTAINING YOUR VEHICLE

Lubricant Selection
Refer to “Fluids, Lubricants, And Genuine Parts” in
“Maintaining Your Vehicle” for further information.
NOTE: The presence of water in the gear lubricant will
result in corrosion and possible failure of differential
components. Operation of the vehicle in water, as may be
encountered in some off-highway types of service, will
require draining and refilling the axle to avoid damage.
Limited-Slip Differentials DO NOT REQUIRE any
limited slip oil additive (friction modifiers).
NOTE: Slight noise and mild shuddering may be evident
while turning a vehicle with limited slip differential on
concrete or dry pavement. These conditions should be
considered normal operation of the limited slip differen-
tial. Transfer Case
Drain And Refill
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
Lubricant Selection
Refer to “Fluids, Lubricants, And Genuine Parts” in
“Maintaining Your Vehicle” for further information.
Fluid Level Check
This fluid level can be checked by removing the filler
plug. The fluid level should be to the bottom edge of the
filler plug hole with the vehicle in a level position.
Automatic Transmission — If Equipped
Selection Of Lubricant
It is important to use the proper transmission fluid to
ensure optimum transmission performance and life. Use596 MAINTAINING YOUR VEHICLE

only the manufacturer ’s specified transmission fluid.
Refer to “Fluids, Lubricants, And Genuine Parts” in this
section for fluid specifications. It is important to maintain
the transmission fluid at the correct level using the
recommended fluid. No chemical flushes should be used
in any transmission; only the approved lubricant should
be used.
CAUTION!Using a transmission fluid other than the manufac-
turer ’s recommended fluid may cause deterioration
in transmission shift quality and/or torque converter
shudder, and will require more frequent fluid and
filter changes. Refer to “Fluids, Lubricants, And
Genuine Parts” in this section for fluid specifica-
tions. Special Additives
The manufacturer strongly recommends against using
any special additives in the transmission. Automatic
Transmission Fluid (ATF) is an engineered product and
its performance may be impaired by supplemental addi-
tives. Therefore, do not add any fluid additives to the
transmission. Avoid using transmission sealers as they
may adversely affect seals.
CAUTION!Do not use chemical flushes in your transmission as
the chemicals can damage your transmission compo-
nents. Such damage is not covered by the New
Vehicle Limited Warranty. 7MAINTAINING YOUR VEHICLE 597
