Floor Mat Safety Information
Always use floor mats designed to fit your vehicle. Only use
a floor mat that does not interfere with the operation of the
accelerator, brake or clutch pedals. Only use a floor mat that
is securely attached using the floor mat fasteners so it cannot
slip out of position and interfere with the accelerator, brake
or clutch pedals or impair safe operation of your vehicle in
other ways.
WARNING!
An improperly attached, damaged, folded, or stacked
floor mat, or damaged floor mat fasteners may cause
your floor mat to interfere with the accelerator, brake, or
clutch pedals and cause a loss of vehicle control. To
prevent SERIOUS INJURY or DEATH:
• ALWAYS securely attach your floor mat using the floor mat fasteners. DO NOT install your floor mat
upside down or turn your floor mat over. Lightly pull to
confirm mat is secured using the floor mat fasteners on
a regular basis.
• ALWAYS REMOVE THE EXISTING FLOOR MAT
FROM THE VEHICLE before installing any other
floor mat. NEVER install or stack an additional floor
mat on top of an existing floor mat.
• ONLY install floor mats designed to fit your vehicle. NEVER install a floor mat that cannot be properly
attached and secured to your vehicle. If a floor mat
needs to be replaced, only use a FCA approved floor
mat for the specific make, model, and year of your
vehicle.
• ONLY use the driver’s side floor mat on the driver’s side floor area. To check for interference, with the
vehicle properly parked with the engine off, fully
depress the accelerator, the brake, and the clutch pedal
(if present) to check for interference. If your floor mat
interferes with the operation of any pedal, or is not
secure to the floor, remove the floor mat from the
vehicle and place the floor mat in your trunk.
• ONLY use the passenger’s side floor mat on the passenger’s side floor area.

Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts and
cracks. Inspect sidewalls for cuts, cracks, and bulges. Check
the wheel bolts for tightness. Check the tires (including
spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight parking for
fuel, coolant, oil, or other fluid leaks. Also, if gasoline fumes
are detected or if fuel, or brake fluid leaks are suspected. The
cause should be located and corrected immediately.
• ALWAYS make sure objects cannot fall or slide into the
driver’s side floor area when the vehicle is moving.
Objects can become trapped under accelerator, brake,
or clutch pedals and could cause a loss of vehicle
control.
• NEVER place any objects under the floor mat (e.g., towels, keys, etc.). These objects could change the posi -
tion of the floor mat and may cause interference with
the accelerator, brake, or clutch pedals.
• If the vehicle carpet has been removed and re-installed, always properly attach carpet to the floor and check the
floor mat fasteners are secure to the vehicle carpet.
Fully depress each pedal to check for interference with
the accelerator, brake, or clutch pedals then re-install
the floor mats.
• It is recommended to only use mild soap and water to clean your floor mats. After cleaning, always check
your floor mat has been properly installed and is
secured to your vehicle using the floor mat fasteners by
lightly pulling mat.

298 STARTING AND OPERATING
PARKING BRAKE
Before leaving the vehicle, make sure that the parking brake
is fully applied. Also, be certain to leave the transmission in
PARK.
The foot operated parking brake is located below the lower
left corner of the instrument panel. To apply the park brake,
firmly push the park brake pedal fully. To release the
parking brake, pull the parking brake release handle.Parking Brake Release When the parking brake is applied with the ignition switch
ON, the “Brake Warning Light” in the instrument cluster
will illuminate.
NOTE:
• When the parking brake is applied and the transmission is
placed in gear, the “Brake Warning Light” will flash. If
vehicle speed is detected, a chime will sound to alert the
driver. Fully release the parking brake before attempting
to move the vehicle.
• This light only shows that the parking brake is applied. It does not show the degree of brake application.
When parking on a hill, it is important to turn the front
wheels toward the curb on a downhill grade and away from
the curb on an uphill grade. Apply the parking brake before
placing the gear selector in PARK, otherwise the load on the
transmission locking mechanism may make it difficult to
move the gear selector out of PARK. The parking brake
should always be applied whenever the driver is not in the
vehicle.

AUTOMATIC TRANSMISSION
WARNING!
• Never use the PARK position as a substitute for the parking brake. Always apply the parking brake fully
when parked to guard against vehicle movement and
possible injury or damage.
• Never leave children alone in a vehicle, or with access to an unlocked vehicle. Leaving unattended children in
a vehicle is dangerous for a number of reasons. A child
or others could be seriously or fatally injured.
• Do not leave the key fob in or near the vehicle, or in a location accessible to children, and do not leave a
vehicle equipped with Keyless Enter-N-Go in the ACC
or ON/RUN mode. A child could operate power
windows, other controls, or move the vehicle.
• Be sure the parking brake is fully disengaged before driving; failure to do so can lead to brake failure and a
collision.
• Always fully apply the parking brake when leaving your vehicle or it may roll and cause damage or injury.
Also, be certain to leave the transmission in PARK.
Failure to do so may cause the vehicle to roll and cause
damage or injury.CAUTION!
If the Brake System Warning Light remains on with the
parking brake released, a brake system malfunction is
indicated. Have the brake system serviced by an
authorized dealer immediately.
WARNING!
• Never use the PARK position as a substitute for the parking brake. Always apply the parking brake fully
when exiting the vehicle to guard against vehicle move -
ment and possible injury or damage.
• Your vehicle could move and injure you and others if it is not in PARK. Check by trying to move the transmis -
sion gear selector out of PARK with the brake pedal
released. Make sure the transmission is in PARK before
exiting the vehicle.

312 STARTING AND OPERATING
NOTE:
Do not attempt to make a shift while only the front or rear
wheels are spinning. This could cause damage to driveline
components.
When operating your vehicle in 4WD LOW, the engine
speed is approximately three times that of the 2WD or 4WD
HIGH positions at a given road speed. Take care not to over-
speed the engine and do not exceed 25 mph (40 km/h).
Proper operation of four-wheel drive vehicles depends on
tires of equal size, type and circumference on each wheel.
Any difference in tire size can cause damage to the drive -
train.
Because four-wheel drive provides improved traction, there
is a tendency to exceed safe turning and stopping speeds. Do
not go faster than road conditions permit. Shifting Procedure
NOTE:
• If any of the requirements to select a new transfer case
position have not been met, the transfer case will not shift.
The position indicator light for the previous position will
remain ON and the newly selected position indicator light
will continue to flash until all the requirements for the
selected position have been met.
• If all the requirements to select a new transfer case position have been met, the current position indicator light will
turn OFF, the selected position indicator light will flash
until the transfer case completes the shift. When the shift is
complete, the position indicator light for the selected posi -
tion will stop flashing and remain ON.
2WD To 4WD HIGH
Push the desired position on the 4WD control switch to shift
the transfercase. Shifts between 2WD and 4WD HIGH can be
done with the vehicle stopped or in motion. With the vehicle
in motion, the transfer case will engage/disengage faster if
you momentarily release the accelerator pedal after turning
the control switch. If the vehicle is stopped, the ignition
switch must be in the ON position with the engine either
running or off. This shift cannot be completed if the ignition
switch is in the ACC position.
WARNING!

Always engage the parking brake when powering down the
vehicle if the “SVC 4WD Warning Light” is illuminated.
Not engaging the parking brake may allow the vehicle to
roll which may cause personal injury or death.

STARTING AND OPERATING 315
The “Transfer Case Position Indicator Light” in the instru-
ment cluster will alert the driver that the vehicle is in
four-wheel drive and that the front and rear driveshafts are
locked together. This light will illuminate when the transfer
case is shifted into either the 4H or 4L position. There is no
light for the 2H or NEUTRAL positions on some models.
When operating your vehicle in 4L, the engine speed is
approximately three times that of the 2H or 4H positions at a
given road speed. Take care not to overspeed the engine and
do not exceed 25 mph (40 km/h).
Proper operation of four-wheel drive vehicles depends on
tires of equal size, type and circumference on each wheel.
Any difference will adversely affect shifting and can cause
damage to the drivetrain.
NOTE:
Do not attempt to make a shift while only the front or rear
wheels are spinning, as this can cause damage to driveline
components.
Because four-wheel drive provides improved traction, there
is a tendency to exceed safe turning and stopping speeds. Do
not go faster than road conditions permit.NOTE:
Delayed shifts out of four-wheel drive may be experienced
due to uneven tire wear, low or uneven tire pressures, exces
-
sive vehicle loading, or cold temperatures.
Two-Wheel Drive High Range (2H)
Rear-Wheel Drive High Range — This range is for normal
street and highway driving on dry hard surfaced roads.
Four-Wheel Drive High Range (4H)
Four-Wheel Drive High Range — This range locks the front
and rear driveshafts together forcing the front and rear
wheels to rotate at the same speed. Additional traction for
loose, slippery road surfaces only.
WARNING!
You or others could be injured or killed if you leave the
vehicle unattended with the transfer case in the
NEUTRAL position without first fully engaging the
parking brake. The transfer case NEUTRAL position
disengages both the front and rear drive shafts from the
powertrain and will allow the vehicle to roll, even if the
transmission is in PARK. The parking brake should
always be applied when the driver is not in the vehicle.

STARTING AND OPERATING 325
Water Fording Characteristics
Water fording characteristic is the vehicle's ability to cross a
body of still water, where the powertrain and drivetrain are
safe from water ingestion. This vehicle has high water
fording characteristics with the ability to cross a pool of
water, without stopping, 24 inches (60 cm) deep at a
maximum speed of 10 mph (16 km/h) and a pool of water
30 inches (76 cm) deep at a maximum speed of 5 mph (8 km/
h), both with an entrance ramp angle of 1.3 degrees.
Simultaneous Brake And Throttle Operation
Many off-road driving conditions require the simultaneous
use of the brake and throttle (two footed driving). When
climbing rocks, logs, or other stepped objects, using light
brake pressure with light throttle will keep the vehicle from
jerking or lurching. This technique is also used when you
need to stop and restart a vehicle on a steep incline.The Basics Of Off-Road Driving
You will encounter many types of terrain driving off-road.
You should be familiar with the terrain and area before
proceeding. There are many types of surface conditions:
hard packed dirt, gravel, rocks, grass, sand, mud, snow and
ice. Every surface has a different effect on your vehicle's
steering, handling and traction. Controlling your vehicle is
one of the keys to successful off-road driving, so always keep
a firm grip on the steering wheel and maintain a good
driving posture. Avoid sudden accelerations, turns or
braking. In most cases there are no road signs, posted speed
limits or signal lights. Therefore you will need to use your
own good judgment on what is safe and what isn't. When on
a trail you should always be looking ahead for surface obsta
-
cles and changes in terrain. The key is to plan your future
driving route while remembering what you are currently
driving over.
CAUTION!
The door sill height is 25 inches (63.5 cm). Water may
intrude into the interior of the vehicle at greater depths.
WARNING!
Always wear your seat belt and firmly tie down cargo.
Unsecured cargo can become projectiles in an off-road
situation.

STARTING AND OPERATING 327
entering any mud hole, get out and determine how deep it
is, if there are any hidden obstacles and if the vehicle can
be safely recovered if stuck.
• Sand – Soft sand is very difficult to travel through with full
tire pressure. When crossing soft sandy spots in a trail
maintain your vehicle's momentum and do not stop. The
key to driving in soft sand using the appropriate tire pres -
sure, accelerating slowly, avoiding abrupt maneuvers and
maintaining the vehicle's momentum. If you are going to
be driving on large soft sandy areas or dunes, reduce your
tire pressure to a minimum of 15 psi (103 kPa) to allow for
a greater tire surface area. Reduced tire pressure will dras -
tically improve your traction and handling, while driving
on the soft sand, but you must return the tires to normal air
pressure before driving on pavement or other hard
surfaces. Be sure you have a way to air the tires back up
prior to reducing the pressure.Crossing Obstacles (Rocks And Other High Points)

While driving off road, you will encounter many types of
terrain. These varying types of terrain bring different types of
obstacles. Before proceeding review the path ahead to deter -
mine the correct approach and your ability to safely recover the
vehicle if something goes wrong. Keeping a firm grip on the
steering wheel, bring the vehicle to a complete stop and then
inch the vehicle forward until it makes contact with the object.
Apply the throttle lightly while holding a light brake pressure
and ease the vehicle up and over the object.

Using A Spotter
There are many times where it is hard to see the obstacle or
determine the correct path. Determining the correct path can
be extremely difficult when you are confronting many obsta -
cles. In these cases have someone guide you over, through, or
around the obstacle. Have the person stand a safe distance in
front of you where they can see the obstacle, watch your tires
and undercarriage, and guide you through.
CAUTION!
Reduced tire pressures may cause tire unseating and
total loss of air pressure. To reduce the risk of tire
unseating, while at a reduced tire pressure, reduce your
speed and avoid sharp turns or abrupt maneuvers.
WARNING!
Crossing obstacles can cause abrupt steering system
loading which could cause you to loose control of your
vehicle.
5

328 STARTING AND OPERATING
Crossing Large Rocks
When approaching large rocks, choose a path which ensures
you drive over the largest with your tires. This will lift your
undercarriage over the obstacle. The tread of the tire is
tougher and thicker than the side wall and is designed to
take the abuse. Always look ahead and make every effort to
cross the large rocks with your tires.
Crossing A Ravine, Gully, Ditch, Washout Or Rut
When crossing a ravine, gully, ditch, washout or a large rut,
the angled approach is the key to maintaining your vehicle's
mobility. Approach these obstacles at a 45-degree angle and
let each tire go through the obstacle independently. You
need to use caution when crossing large obstacles with steep
sides. Do not attempt to cross any large obstacle with steep
sides at an angle great enough to put the vehicle at risk of a
rollover. If you get caught in a rut, dig a small trench to the
right or left at a 45-degree angle ahead of the front tires. Usethe removed dirt to fill the rut ahead of the turnout you just
created. You should now be able to drive out following the
trench you just created at a 45-degree angle.
Crossing Logs
To cross a log, approach it at a slight angle (approximately 10
to 15 degrees). This allows one front tire to be on top of the
log while the other just starts to climb the log. While climbing
the log, modulate your brake and accelerator to avoid spin
-
ning the log out from under your tires. Then ease the vehicle
off the log using your brakes.
CAUTION!
• Never attempt to straddle a rock that is large enough to strike your axles or undercarriage.
• Never attempt to drive over a rock which is large enough to contact the door sills.
WARNING!
There is an increased risk of rollover when crossing an
obstacle, at any angle, with steep sides.
CAUTION!
Do not attempt to cross a log with a greater diameter than
the running ground clearance or the vehicle will become
high centered.

330 STARTING AND OPERATING
provide enough traction to complete the climb. If you do
not make it to the top, place the vehicle in REVERSE and
back straight down the grade using engine resistance
along with the vehicle brakes.
• Driving Down Hill – Before driving down a steep hill you
need to determine if it is too steep for a safe descent. What
is the surface traction? Is the grade too steep to maintain a
slow controlled descent? Are there obstacles? Is it a
straight descent? Is there plenty of distance at the base of
the hill to regain control if the vehicle descends too fast? If
you feel confident in your ability to proceed then make
sure you are in 4LO (Low Range) with the transmission in
first gear (manually select first gear on automatic transmis -
sions) and proceed with caution. Allow engine braking to
control the descent and apply your brakes if necessary, but
do not allow the tires to lock. •
Driving Across An Incline – If at all possible avoid
driving across an incline. If it is necessary, know your
vehicle's abilities. Driving across an incline places more
weight on the down hill wheels, which increases the possi -
bilities of a down hill slide or rollover. Make sure the
surface has good traction with firm and stable soils. If
possible transverse the incline at an angle heading slightly
up or down.
• If You Stall Or Begin To Lose Headway – If you stall or
begin to lose headway while climbing a steep hill, allow
your vehicle to come to a stop and immediately apply the
brake. Restart the engine and shift into REVERSE. Back
slowly down the hill allowing the compression braking of
the engine and transmission to help regulate your speed. If
WARNING!
Never attempt to climb a hill at an angle or turn around
on a steep grade. Driving across an incline increases the
risk of a roll over, which may result in severe injury or
death.
WARNING!
Do not descend a steep grade in NEUTRAL. Use vehicle
brakes in conjunction with engine braking. Descending
a grade too fast could cause you to lose control and be
seriously injured or killed.
WARNING!
Driving across an incline increases the risk of a rollover,
which may result in severe injury.
