SAFETY TIPS   
TRANSPORTING PASSENGERS
NEVER TRANSPORT PASSENGERS IN THE 
CARGO AREA.
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 CHECKS YOU SHOULD MAKE 
I
NSIDE 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.
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 seat -
backs as you remove slack in the strap.
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.

Air Bag Warning Light  
The Air Bag Warning Light   will turn on for four 
to eight seconds as a bulb check when the 
ignition switch is first placed in 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 
illuminate 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 immediately  Ú page 292.
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 
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 inter -
ference, with the vehicle properly parked 
with the engine off, fully depress the accel -
erator, 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.

PERIODIC SAFETY CHECKS YOU SHOULD 
M
AKE 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 lug nuts/bolt torque 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.
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 objects 
could change the position of the floor mat 
and may cause interference with the accel -
erator, 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.
WARNING!  (Continued)
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.

SAFETY333
EXHAUST GAS    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 
an authorized dealer 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 addition, inspect the exhaust 
system each time the vehicle is raised for 
lubrication or oil change. Replace as required.
CARBON MONOXIDE WARNINGS  
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.
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.
WARNING!
Carbon monoxide (CO) in exhaust gases is 
deadly. Follow the precautions below to 
prevent carbon monoxide poisoning:
Do not inhale exhaust gases. They contain 
carbon monoxide, a colorless and odorless 
gas, which can kill. Never run the engine in 
a closed area, such as a garage, and never 
sit in a parked vehicle with the engine 
running for an extended period. If the 
vehicle is stopped in an open area with
the engine running for more than a short 
period, adjust the ventilation system to 
force fresh, outside air into the vehicle.
Guard against carbon monoxide with 
proper maintenance. Have the exhaust 
system inspected every time the vehicle is 
raised. Have any abnormal conditions 
repaired promptly. Until repaired, drive with 
all side windows fully open.
