Maintenance and Modifications
The suspension and steering systems on
your vehicle have been designed and
tested to provide predictable performance
whether loaded or empty. For this reason,
we strongly recommend that you do not
make modifications such as adding or
removing parts, for example, lift kits or
stabilizer bars, or by using replacement
parts not equivalent to the original factory
equipment.
We recommend that you use caution when
your vehicle has either a high-load or
device, for example, a ladder or luggage
racks. Any modifications to your vehicle
that raise the center of gravity could cause
your vehicle to roll over when there is a loss
of vehicle control.
Failure to maintain your vehicle correctly
could void the warranty, increase your
repair cost, reduce vehicle performance
and operational capabilities, and adversely
affect you and your passenger's safety. We
recommend you frequently inspect your
vehicle's chassis components when your
vehicle is subject to off-road usage.

Trail Control allows you to set a speed
between 1 mph (1.6 km/h) to 14 mph
(23 km/h) in a forward motion and 1 mph
(1.6 km/h) to 5 mph (8 km/h) in reverse.
The system controls acceleration and
braking in difficult off-road environments,
which allows you to focus on steering. See
What Is Trail Control
(page 184).
Trail Control Performance:
• Manages wheel slip to maximize
traction.
• Removes the need for you to use both
feet when driving in off-road situations.
• Provides braking to maximize traction
in descents.
• Gives you confidence in difficult
environments.
After Driving Your Vehicle Off-
Road WARNING:
After off-road use,
before returning to the road, check the
wheels and tires for damage. Off-road
use may cause damage to your wheels
and tires that can lead to tire failure, loss
of vehicle control, serious injury or death.
Driving off-road places more stress on your
vehicle than most on-road driving. After
driving off-road, check for damage to the
wheels, chassis and underbody.
Inspect the underbody of your vehicle by
checking tires, body structure, steering,
suspension, and exhaust system for
damage.
Inspect the tires for any cuts in the tread
or sidewall area. Also inspect the sidewall
for any bulge indicating damage to the tire.
Make sure that tires are inflated to proper
tire pressure as indicated on the tire
placard. Check the radiator for mud and debris and
clean as needed.
Check that the air filter is clean and dry.
Remove accumulations of plants or brush.
These things could be a fire hazard or hide
damage to the fuel lines, brake hoses, and
propeller shafts.
Make sure that the grille and radiator are
clear of any obstructions that may affect
cooling.
After extended operation in mud, sand,
water, or similar dirty conditions, inspect
the wipers and washers to make sure they
are working.
Note:
Mud caked windows are hard to see
through and can damage wiper blades or
motor.
Check wipers for debris or anything that
may scratch the windshield.
If you experience unusual vibration after
driving in mud, slush or similar conditions,
check the wheels for impacted material.
Impacted material can cause vibrations
when driving and wheel imbalance.
Remove the material to reduce the
vibration.
Note: If you have removed the impacted
material from the wheels and your vehicle
still has a vibration check your vehicle for
damage or see an authorized dealer.
Inspect the exhaust system for damage or
looseness.
Make sure that the brakes are in proper
working order and free of any mud, stones
and debris, which can become trapped
around the brake rotor, backing plate and
caliper.
Inspect the wheels for dents, cracks, or
other damage.

replace it with your spare tire and
wheel. If you cannot detect a
cause, have the vehicle towed to
the nearest repair facility or tire
dealer to have the vehicle
inspected.
Tire and Wheel Alignment
A bad jolt from hitting a curb or
pothole can cause the front end
of your vehicle to become
misaligned or cause damage to
your tires. If your vehicle seems to
pull to one side when you are
driving, the wheels may be out of
alignment. Have an authorized
dealer check the wheel alignment
periodically.
Wheel misalignment in the front
or the rear can cause uneven and
rapid treadwear of your tires and
should be corrected by an
authorized dealer. Front-wheel
drive vehicles and those with an
independent rear suspension (if
equipped) may require alignment
of all four wheels.
The tires should also be balanced
periodically. An unbalanced tire
and wheel assembly may result in
irregular tire wear.
Tire Rotation
Note:
If your tires show uneven
wear, ask an authorized dealer to
check for and correct any wheel
misalignment, tire imbalance or
mechanical problem involved
before tire rotation. Note:
Your vehicle may be
equipped with a dissimilar spare
wheel and tire assembly. A
dissimilar spare wheel and tire
assembly is defined as a spare
wheel and tire assembly that is
different in brand, size or
appearance from the road tires and
wheels. If you have a dissimilar
spare wheel and tire assembly, it is
intended for temporary use only
and should not be used in a tire
rotation.
Note: After having your tires
rotated, inflation pressure must be
checked and adjusted to the
vehicle requirements.
Rotating your tires at the
recommended interval will help
your tires wear more evenly,
providing better tire performance
and longer tire life. Sometimes
irregular tire wear can be
corrected by rotating the tires.
