Transporting Pets
Air Bags deploying in the front seat could harm
your pet. An unrestrained pet will be thrown
about and possibly injured, or injure a
passenger during panic braking or in a collision.
Pets should be restrained in the rear seat (if
equipped) in pet harnesses or pet carriers that
are secured by seat belts.
SAFETY TIPS
Transporting Passengers
NEVER TRANSPORT PASSENGERS IN THE
CARGO AREA.
Exhaust Gas The best protection against carbon monoxide
entry into the vehicle body is a properly main
-
tained engine exhaust system.
Whenever a change is noticed in the sound of
the exhaust system, when exhaust fumes can
be detected inside the vehicle, or when the
underside or rear of the vehicle is damaged,
have a competent mechanic inspect the
complete exhaust system and adjacent body
areas for broken, damaged, deteriorated, or
mispositioned parts. Open seams or loose
connections could permit exhaust fumes to
seep into the passenger compartment. In addi -
tion, inspect the exhaust system each time the
vehicle is raised for lubrication or oil change.
Replace as required.
WARNING!
Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury or
death.
It is extremely dangerous to ride in a cargo
area, inside or outside of a vehicle. In a
collision, people riding in these areas are
more likely to be seriously injured or killed.
Do not allow people to ride in any area of
your vehicle that is not equipped with seats
and seat belts.
Be sure everyone in your vehicle is in a seat
and using a seat belt properly.
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you
unconscious and can eventually poison you.
To avoid breathing (CO), follow these safety
tips:
Do not run the engine in a closed garage or
in confined areas any longer than needed
to move your vehicle in or out of the area.
If you are required to drive with the trunk/
liftgate/rear doors open, make sure that all
windows are closed and the climate control
BLOWER switch is set at high speed. DO
NOT use the recirculation mode.
WARNING! (Continued)
If it is necessary to sit in a parked vehicle
with the engine running, adjust your
heating or cooling controls to force outside
air into the vehicle. Set the blower at high
speed.

Safety Checks You Should Make Inside The
Vehicle
Seat Belts
Inspect the seat belt system periodically,
checking for cuts, frays, and loose parts.
Damaged parts must be replaced immediately.
Do not disassemble or modify the system.
Front seat belt assemblies must be replaced
after a collision. Rear seat belt assemblies must
be replaced after a collision if they have been
damaged (i.e., bent retractor, torn webbing,
etc.). If there is any question regarding seat belt
or retractor condition, replace the seat belt.
Air Bag Warning Light
The Air Bag warning light will turn on for four
to eight seconds as a bulb check when the igni -
tion switch is first turned to ON/RUN. If the light
is either not on during starting, stays on, or
turns on while driving, have the system
inspected at an authorized dealer as soon as
possible. After the bulb check, this light will illu -
minate with a single chime when a fault with the
Air Bag System has been detected. It will stay on until the fault is removed. If the light comes on
intermittently or remains on while driving, have
an authorized dealer service the vehicle imme
-
diately.
Refer to “Occupant Restraint Systems” in
“Safety” for further information.
Defroster
Check operation by selecting the defrost mode
and place the blower control on high speed. You
should be able to feel the air directed against
the windshield. See an authorized dealer for
service if your defroster is inoperable.
Floor Mat Safety Information
Always use floor mats designed to fit your
vehicle. Only use a floor mat that does not inter -
fere 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.

256STARTING AND OPERATING
firm grip on the steering wheel and maintain a
good driving posture. Avoid sudden accelera -
tions, 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 obstacles and changes in
terrain. The key is to plan your future driving
route while remembering what you are currently
driving over.
When To Use Low Range
When driving off-road, shift into 4WD LOW for
additional traction or to improve handling and
control on slippery or difficult terrain. Due to the lower gearing, low range will allow the engine to
operate in a higher power range. This will allow
you to idle over obstacles and down hills, with
improved control and less effort. Also, use 4WD
LOW in rain, ice, snow, mud, and sand to get
heavy loads rolling, improve traction, or when
-
ever 4WD HIGH traction will not do the job.
Driving In Snow, Mud And Sand
There is a drastic reduction in traction when
driving in snow, mud or sand. The vehicle will be
less responsive to steering, acceleration and
braking inputs. Therefore you should accelerate
slowly, leave greater stopping distances and
avoid abrupt vehicle maneuvers. You want to
keep a slow constant steady pace. The key is to
maintain the vehicle's momentum.
Snow – In heavy snow or for additional
control and traction at slower speeds, shift
the transmission to a low gear and shift the
transfer case to 4WD LOW if necessary. Do
not shift to a lower gear than necessary to
maintain headway. Over-revving the engine
can spin the wheels and traction will be lost.
If you start to slow to a stop, try turning your
steering wheel no more than a quarter turn
quickly back and forth, while still applying throttle. This will allow the tires to get a fresh
"bite" and help maintain your momentum.
Mud
– Deep mud creates a great deal of
suction around the tires and is very difficult to
get through. You should use 4WD LOW with a
gear low enough to maintain your momentum
without shifting. If you start to slow to a stop,
try turning your steering wheel no more than
a quarter turn quickly back and forth for addi -
tional traction. Mud holes pose an increased
threat of vehicle damage and getting stuck.
They are normally full of debris from previous
vehicles getting stuck. As a good practice
before 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
WARNING!
Always wear your seat belt and firmly tie down
cargo. Unsecured cargo can become
projectiles in an off-road situation.
CAUTION!
Never park your vehicle over dry grass or
other combustible materials. The heat from
your vehicle exhaust system could cause a
fire.
CAUTION!
On icy or slippery roads, do not downshift at
high engine RPMs or vehicle speeds because
engine braking may cause skidding and loss
of control.
