It is recommended you contact your authorized tire
dealer or original equipment dealer with any questions
you may have on tire specifications or capability. Failure
to use equivalent replacement tires may adversely affect
the safety, handling, and ride of your vehicle.
WARNING!
•Do not use a tire, wheel size or rating other than
that specified for your vehicle. Some combinations
of unapproved tires and wheels may change sus-
pension dimensions and performance characteris-
tics, resulting in changes to steering, handling, and
braking of your vehicle. This can cause unpredict-
able handling and stress to steering and suspen-
sion components. You could lose control and have
a collision resulting in serious injury or death. Use
only the tire and wheel sizes with load ratings
approved for your vehicle.
(Continued)
WARNING! (Continued)
•Never use a tire with a smaller load index or
capacity, other than what was originally equipped
on your vehicle. Using a tire with a smaller load
index could result in tire overloading and failure.
You could lose control and have a collision.
• Failure to equip your vehicle with tires having
adequate speed capability can result in sudden tire
failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer read-
ings.

Adjusting GAIN
NOTE:This should only be performed in a traffic free
environment at speeds of approximately 20–25 mph
(30–40 km/h).
1. Make sure the trailer brakes are in good working condition, functioning normally and properly ad-
justed. See your trailer dealer if necessary.
2.
Hook up the trailer and make the electrical connections
according to the trailer manufacturer’s instructions.
3. When a trailer with electric/EOH brakes is plugged in, the trailer connected message should appear in the
EVIC/DID (if the connection is not recognized by the
ITBM, braking functions will not be available), the
GAIN setting will illuminate and the correct type of
trailer must be selected from the EVIC/DID options.
4. Push the UP or DOWN button on the steering wheel until “TRAILER TOW” appears on the screen. 5. Push the RIGHT arrow on the steering wheel to enter
“TRAILER TOW”.
6. Push the UP or DOWN buttons until Trailer Brake Type appears on the screen.
7. Push the RIGHT arrow and then push the UP or DOWN buttons until the proper Trailer Brake Type
appears on the screen.
8.
In a traffic-free environment, tow the trailer on a dry,
level surface at a speed of 20–25 mph (30–40 km/h) and
squeeze the manual brake control lever completely.
9. If the trailer wheels lockup (indicated by squealing tires), reduce the GAIN setting; if the trailer wheels
turn freely, increase the GAIN setting.
Repeat steps 8 and 9 until the GAIN setting is at a point
just below trailer wheel lockup. If towing a heavier
trailer, trailer wheel lockup may not be attainable even
with the maximum GAIN setting of 10.

4. Disconnect the opposite end of the positive(+)jumper
cable from the positive (+)post of the vehicle with the
discharged battery.
If frequent jump-starting is required to start your vehicle
you should have the battery and charging system in-
spected at your authorized dealer.
CAUTION!
Accessories plugged into the vehicle power outlets
draw power from the vehicle’s battery, even when not
in use (i.e., cellular devices, etc.). Eventually, if
plugged in long enough without engine operation,
the vehicle’s battery will discharge sufficiently to
degrade battery life and/or prevent the engine from
starting.
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

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.
WARNING!
• Do not use a chain for freeing a stuck vehicle.
Chains may break, causing serious injury or death.
• Stand clear of vehicles when pulling with tow
hooks. Tow straps may become disengaged, caus-
ing serious injury.
CAUTION!
Tow hooks are for emergency use only to rescue a
vehicle stranded off-road. Do not use tow hooks for
tow truck hookup or highway towing. You could
damage your vehicle.
SHIFT LEVER OVERRIDE
If a malfunction occurs and the shift lever cannot be
moved out of the PARK position, you can use the
following procedure to temporarily move the shift lever:
1. Turn the engine OFF.
2. Firmly apply the parking brake.
3. Tilt the steering wheel to the full up position.
4. Push and maintain firm pressure on the brake pedal.6

•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 OFFthe 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 ALLwheels 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.
