4. Remove slack in the tether strap accord-
ing to the child restraint manufacturer’s
instructions.
WARNING!
• An incorrectly anchored tether strap
could lead to increased head motion and
possible injury to the child. Use only the
anchorage position directly behind the
child seat to secure a child restraint top
tether strap.
• If your vehicle is equipped with a split
rear seat, make sure the tether strap
does not slip into the opening between
the seatbacks as you remove slack in the
strap.
Installing Child Restraints Using The Ve-
hicle Seat Belt
Child restraint systems are designed to be
secured in vehicle seats by lap belts or the
lap belt portion of a lap/shoulder belt.
WARNING!
• Improper installation or failure to prop-
erly secure a child restraint can lead to
failure of the restraint. The child could
be badly injured or killed.
WARNING!
• Follow the child restraint manufactur-
er’s directions exactly when installing an
infant or child restraint.
The seat belts in the rear passenger seating
positions are equipped with a Switchable
Automatic Locking Retractor (ALR) that is
designed to keep the lap portion of the seat
belt tight around the child restraint. The ALR
retractor can be “switched” into a locked
mode by pulling all of the webbing out of the
retractor and then letting the webbing retract
back into the retractor. If it is locked, the ALR
will make a clicking noise while the webbing
is pulled back into the retractor. Refer to the
“Automatic Locking Mode” description in
“Switchable Automatic Locking Retractors
(ALR)” under “Occupant Restraint Systems”
for additional information on ALR.
How To Stow An Unused Switchable-ALR
(ALR) Seat Belt:
When using the ISOFIX attaching system to
install a child restraint, stow all ALR seat
belts that are not being used by other occu-
pants or being used to secure child restraints.

SAFETY
110

An unused belt could injure a child if they
play with it and accidentally lock the seat belt
retractor. Before installing a child restraint
using the ISOFIX system, buckle the seat belt
behind the child restraint and out of the
child’s reach. If the buckled seat belt inter-
feres with the child restraint installation, in-
stead of buckling it behind the child re-
straint, route the seat belt through the child
restraint belt path and then buckle it. Do not
lock the seat belt. Remind all children in the
vehicle that the seat belts are not toys and
that they should not play with them.
Installing A Child Restraint With A Switch-
able Automatic Locking Retractor (ALR)
Child restraint systems are designed to be
secured in vehicle seats by lap belts or the lap
belt portion of a lap/shoulder belt.
WARNING!
• Improper installation or failure to prop-
erly secure a child restraint can lead to
failure of the restraint. The child could
be badly injured or killed.
WARNING!
• Follow the child restraint manufacturer’s
directions exactly when installing an in-
fant or child restraint.
1. Place the child seat in the center of the
seating position. For some second row
seats, you may need to recline the seat
and/or raise the head restraint to get a
better fit. If the rear seat can be moved
forward and rearward in the vehicle, you
may wish to move it to its rear-most posi-
tion to make room for the child seat. You
may also move the front seat forward to
allow more room for the child seat.
2. Pull enough of the seat belt webbing from
the retractor to pass it through the belt
path of the child restraint. Do not twist the
belt webbing in the belt path.
3. Slide the latch plate into the buckle until
you hear a “click.”
4. Pull on the webbing to make the lap
portion tight against the child seat.5. To lock the seat belt, pull down on the
shoulder part of the belt until you have
pulled all the seat belt webbing out of the
retractor. Then, allow the webbing to re-
tract back into the retractor. As the web-
bing retracts, you will hear a clicking
sound. This means the seat belt is now in
the Automatic Locking mode.
6. Try to pull the webbing out of the retractor.
If it is locked, you should not be able to
pull out any webbing. If the retractor is not
locked, repeat step 5.
7. Finally, pull up on any excess webbing to
tighten the lap portion around the child
restraint while you push the child restraint
rearward and downward into the vehicle
seat.
8. Test that the child restraint is installed
tightly by pulling back and forth on the
child seat at the belt path. It should not
move more than 25 mm in any direction.
Any seat belt system will loosen with time, so
check the belt occasionally, and pull it tight if
necessary.
111

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 passen-
ger during panic braking or in a collision.
Pets should be restrained in the rear seat in
pet harnesses or pet carriers that are secured
by seat belts.
SAFETY TIPS
Transporting Passengers
NEVER TRANSPORT PASSENGERS IN THE
CARGO AREA.
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
WARNING!
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.
Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They con-
tain carbon monoxide (CO), which is col-
orless and odorless. Breathing it can make
you unconscious and can eventually poi-
son 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
WARNING!
sure that all windows are closed and the
climate control BLOWER switch is set at
high speed. DO NOT use the recircula-
tion mode.
• 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.
The best protection against carbon monoxide
entry into the vehicle body is a properly
maintained 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 com-
plete exhaust system and adjacent body ar-
eas for broken, damaged, deteriorated, or
mispositioned parts. Open seams or loose
connections could permit exhaust fumes to
seep into the passenger compartment. In
SAFETY
112

addition, inspect the exhaust system each
time the vehicle is raised for lubrication or oil
change. Replace as required.
Safety Checks You Should Make Inside
The Vehicle
Seat Belts
Inspect the seat belt system periodically,
checking for cuts, frays, and loose parts. Dam-
aged 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 web-
bing, etc.). If there is any question regarding
seat belt or retractor condition, replace the
seat belt.
Air Bag Warning Light
The Air Bag warning lightwill turn on for
four to eight seconds as a bulb check when the
ignition 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 in-spected at an authorized dealer as soon as
possible. This light will illuminate with a single
chime when a fault with the Air Bag Warning
Light has been detected, it will stay on until the
fault is removed. If the light comes on intermit-
tently or remains on while driving, have an
authorized dealer service the vehicle immedi-
ately. 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 your
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
interfere with the operation of the pedal as-
semblies. 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 pedal assemblies 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 in-
terfere 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.
113

WARNING!
• 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.
• 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 ob-
jects could change the position of the
floor mat and may cause interference
WARNING!
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 accelera-
tor, 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 se-
cured to your vehicle using the floor mat
fasteners by lightly pulling mat.
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 thetread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts,
cracks, and bulges. Check the wheel nuts 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 lock-
ing.
Fluid Leaks
Check area under 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 imme-
diately.

FlatbedALL BEST METHOD
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 equipment manufac-
turer’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 brack-
ets. State and local laws regarding vehicles
under tow must be observed.
If you must use the accessories (wipers, de-
frosters, etc.) while being towed, the ignition
must be in the ON/RUN position, not the ACC
position.
If 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 flatbed
truck, do not attach to front or rear
suspension components. Damage to
your vehicle may result from improper
towing.
• If the vehicle being towed requires steer-
ing, the ignition switch must be in the
ACC or ON/RUN mode, not in the LOCK/
OFF mode.
Without The Ignition Key
Special care must be taken when the vehicle
is towed with the ignition in the LOCK posi-
tion. The only approved method of towing
without the ignition key is with a flatbed
truck. Proper towing equipment is necessary
to prevent damage to the vehicle.
Four–Wheel Drive Models
The manufacturer recommends towing with
all wheelsOFFthe ground. Acceptable meth-
ods are to tow the vehicle on a flatbed or with
one end of the vehicle raised and the oppo-
site 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, withALL
wheels on the ground),IFthe transfer case is
