Installing Child Restraints Using The
Vehicle Seat Belt
NOTE:If your vehicle is not equipped with a rear seat, FCA
US LLC recommends that you do not allow children
12 years old and under to ride in your vehicle. If the
rear seats are not present in your vehicle, NEVER
install a child restraint in these positions.
Child restraint systems are designed to be secured
in vehicle seats by lap belts or the lap belt portion
of a lap/shoulder belt. The seat belts in the 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 so that it is not necessary to use a locking
clip. 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
on Ú
page 206 for additional information on ALR.
Please see the table below and the following
sections for more information.
Lap/Shoulder Belt Systems For Installing
Child Restraints In This Vehicle
NOTE:If your vehicle is not equipped with a rear seat, FCA
US LLC recommends that you do not allow children
12 years old and under to ride in your vehicle. If the
rear seats are not present in your vehicle, NEVER
install a child restraint in these positions.
WARNING!
Never place a rear-facing child restraint in
front of an air bag. A deploying passenger
front air bag can cause death or serious injury
to a child 12 years or younger, including a
child in a rear-facing child restraint.
Never install a rear-facing child restraint in the
front seat of a vehicle. Only use a rear-facing
child restraint in the rear seat. If the vehicle
does not have a rear seat, do not transport a
rear-facing child restraint in that vehicle.
WARNING!
Improper installation or failure to properly
secure a child restraint can lead to failure of
the restraint. The child could be badly injured
or killed.
Follow the child restraint manufacturer’s
directions exactly when installing an infant or
child restraint.

228SAFETY
Installing A Child Restraint With A
Switchable 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.

1. Place the child seat in the center of the
seating position. If the second row seat can
be reclined, you may recline the seat and/or
raise the head restraint (if adjustable) 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 position 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 retract back into the
retractor. As the webbing 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. If the child restraint has a top tether strap and the seating position has a top tether
anchorage, connect the tether strap to the
anchorage and tighten the tether strap. For
directions to attach a tether anchor, see
Úpage 228.
9. 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
1 inch (25.4 mm) in any direction.
Any seat belt system will loosen with time, so check
the belt occasionally, and pull it tight if necessary.Installing Child Restraints Using The Top
Tether Anchorage:
WARNING!
Improper installation or failure to properly
secure a child restraint can lead to failure of
the restraint. The child could be badly injured
or killed.
Follow the child restraint manufacturer’s
directions exactly when installing an infant or
child restraint.
WARNING!
If the rear or front passenger seats are not
present in your vehicle, NEVER install a child
restraint in these positions.

22_LA_OM_EN_USC_t.book Page 228

SAFETY229

1. Look behind the seating position where you plan to install the child restraint to find the
tether anchorage. You may need to move the
seat forward to provide better access to the
tether anchorage. If there is no top tether
anchorage for that seating position, move the
child restraint to another position in the
vehicle if one is available.

2. Rotate or lift the cover to access the anchor directly behind the seat where you are placing
the child restraint. 3. Route the tether strap to provide the most
direct path for the strap between the anchor
and the child seat. If your vehicle is equipped
with adjustable rear head restraints, raise the
head restraint, and where possible, route the
tether strap under the head restraint and
between the two posts. If not possible, lower
the head restraint and pass the tether strap
around the outboard side of the head restraint.

Tether Strap Mounting
4. Attach the tether strap hook of the child
restraint to the top tether anchorage as shown
in the diagram.
5. Remove slack in the tether strap according to the child restraint manufacturer’s instructions.
NOTE:If your vehicle is not equipped with a rear seat, FCA
US LLC recommends that you do not allow children
12 years old and under to ride in your vehicle. If the
rear seats are not present in your vehicle, NEVER
install a child restraint in these positions. If you
must install a forward facing child restraint in the
front passenger seat, then you must use the seat
belt system to secure the restraint. A top tether
strap extension may be needed to reach the tether
anchor on the rear shelf directly behind the
passenger seat.
WARNING!
Do not attach a tether strap for a rear-facing car
seat to any location in front of the car seat,
including the seat frame or a tether anchorage.
Only attach the tether strap of a rear-facing car
seat to the tether anchorage that is approved for
that seating position, located behind the top of
the vehicle seat. For the location of approved
tether anchorages in your vehicle, see
Úpage 221.

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.

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.
If your vehicle is involved in a collision, or if you
have questions regarding the seat belt or retractor
conditions, take your vehicle to an authorized FCA
dealer or authorized FCA Certified Collision Care
Program facility for inspection.
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
the ON/RUN mode. 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 200.
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!
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat buildup
may cause serious injury or death.
It is extremely dangerous to ride in a cargo
area, inside or outside of a vehicle. In a colli -
sion, 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.

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.
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 interfer -
ence, 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 inter -
feres 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 objects could
change the position of the floor mat and may
cause interference with the accelerator,
brake, or clutch pedals.
WARNING!
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,

JACKING AND CHANGING A TIRE
WARNING!
A loose tire or jack thrown forward in a collision
or hard stop could endanger the occupants of
the vehicle. Always stow the jack parts and the
spare tire in the places provided. Have the
deflated (flat) tire repaired or replaced
immediately.
WARNING!
Carefully follow these tire changing warnings to
help prevent personal injury or damage to your
vehicle:
Always park on a firm, level surface as far from
the edge of the roadway as possible before
raising the vehicle.
Turn on the Hazard Warning Flashers.
Apply the parking brake firmly and place an
automatic transmission in PARK; a manual
transmission in REVERSE or FIRST gear.
Block the wheel diagonally opposite the wheel
to be raised.
Never start or run the engine with the vehicle
on a jack.
Do not let anyone sit in the vehicle when it is
on a jack.

22_LA_OM_EN_USC_t.book Page 238

IN CASE OF EMERGENCY249
NOTE:There are steps that you can take to slow down an
impending overheat condition:
If your Air Conditioner (A/C) is on, turn it off. The
A/C system adds heat to the engine cooling
system and turning the A/C off can help remove
this heat.
You can also turn the temperature control to
maximum heat, the mode control to floor and
the blower control to high. This allows the heater
core to act as a supplement to the radiator and
aids in removing heat from the engine cooling
system.
MANUAL PARK RELEASE — 8–SPEED
TRANSMISSION
In order to move the vehicle in cases where the
transmission will not shift out of PARK (P) (such as
a depleted battery), a Manual Park Release is
available.
Follow these steps to use the Manual Park
Release:

1. Firmly apply the parking brake.

2. Remove the console storage bin to access the
Manual Park Release lever.

Console Storage Bin

WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator.
If you see or hear steam coming from under the
hood, do not open the hood until the radiator
has had time to cool. Never try to open a cooling
system pressure cap when the radiator or
coolant bottle is hot.
CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the temperature gauge reads
HOT (H), pull over and stop the vehicle. Idle the
vehicle with the air conditioner turned off until
the pointer drops back into the normal range. If
the pointer remains on HOT (H), and you hear
continuous chimes, turn the engine off
immediately and call for service.
WARNING!
Always secure your vehicle by fully applying the
parking brake before activating the Manual Park
Release. In addition, you should be seated in the
driver's seat with your foot firmly on the brake
pedal when activating the Manual Park Release.
Activating the Manual Park Release will allow
your vehicle to roll away if it is not secured by the
parking brake, or by proper connection to a tow
vehicle. Activating the Manual Park Release on
an unsecured vehicle could lead to serious
injury or death for those in or around the vehicle.

NOTE:When the lever is in the release position the access
cover cannot be reinstalled.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand, or
snow, it can often be moved using a rocking
motion. Turn the steering wheel right and left to
clear the area around the front wheels. For
vehicles with automatic transmission, push and
hold the lock button on the gear selector. Then
shift back and forth between DRIVE and REVERSE
(with automatic transmission) or FIRST gear and
REVERSE (with manual transmission), while gently
pressing the accelerator. Use the least amount of
accelerator pedal pressure that will maintain the
rocking motion, without spinning the wheels or
racing the engine.

IN CASE OF EMERGENCY253
REAR-WHEEL DRIVE (RWD) MODELS
FCA US LLC recommends towing your vehicle with
all four wheels OFF the ground using a flatbed. If flatbed equipment is not available, and the
transmission is operable, the vehicle may be flat
towed (with all four wheels on the ground) under
the following conditions:
The transmission must be in NEUTRAL (N).
Instructions on shifting the transmission to
NEUTRAL (N) when the engine is off
Ú
page 249.
The towing distance must not exceed 30 miles
(48 km).
The towing speed must not exceed 30 mph
(48 km/h).
If the transmission is not operable, or the vehicle
must be towed faster than 30 mph (48 km/h) or
farther than 30 miles (48 km), then the only
acceptable method of towing is with a flatbed
truck.
ENHANCED ACCIDENT RESPONSE SYSTEM
(EARS)
This vehicle is equipped with an Enhanced
Accident Response System.
This feature is a communication network that
takes effect in the event of an impact Úpage 214.
EVENT DATA RECORDER (EDR)
This vehicle is equipped with an event data
recorder (EDR). The main purpose of an EDR is to
record data that will assist in understanding how a
vehicle’s systems performed under certain crash
or near crash-like situations, such as an air bag
deployment or hitting a road obstacle Úpage 215.
CAUTION!
Do not use sling type equipment when towing.
Vehicle damage may occur.
When securing the vehicle to a flat bed truck,
do not attach to front or rear suspension
components. Damage to your vehicle may
result from improper towing.
FCA US LLC does not recommend towing this
vehicle using a tow dolly. Vehicle damage may
occur.

274SERVICING AND MAINTENANCE
(Continued)
Make sure that the coolant expansion bottle
overflow hoses are not kinked or obstructed.
Keep the front of the radiator clean. If your
vehicle is equipped with air conditioning, keep
the front of the condenser clean.
Do not change the thermostat for Summer or
Winter operation. If replacement is ever neces-
sary, install ONLY the correct type thermostat.
Other designs may result in unsatisfactory
engine cooling performance, poor gas mileage,
and increased emissions.
BRAKE SYSTEM
In order to ensure brake system performance, all
brake system components should be inspected
periodically Ú page 255.
Fluid Level Check — Brake Master Cylinder
Check the fluid level in the master cylinder
immediately if the Brake System Warning Light
indicates system failure.
Check the fluid level in the master cylinder when
performing underhood services.
Clean the top of the master cylinder area before
removing the cap. Add fluid to bring the level up to
the top of the “FULL” mark on the side of the
master cylinder reservoir.
Overfilling of fluid is not recommended because it
may cause leaking in the system.
Add enough fluid to bring the level up to the
requirements described on the brake fluid
reservoir. With disc brakes, fluid level can be
expected to fall as the brake pads wear. However,
low fluid level may be caused by a leak and a
checkup may be needed.
Use only brake fluid that has been recommended
by the manufacturer, and has been kept in a tightly
closed container to avoid contamination from
foreign matter or moisture Ú page 316.
WARNING!
Riding the brakes can lead to brake failure and
possibly a collision. Driving with your foot resting
or riding on the brake pedal can result in
abnormally high brake temperatures, excessive
lining wear, and possible brake damage. You
would not have your full braking capacity in an
emergency.
WARNING!
Use only manufacturer's recommended brake
fluid Úpage 316. Using the wrong type of
brake fluid can severely damage your brake
system and/or impair its performance. The
proper type of brake fluid for your vehicle is
also identified on the original factory installed
hydraulic master cylinder reservoir.
To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that
has been in a tightly closed container. Keep
the master cylinder reservoir cap secured at
all times. Brake fluid in a open container
absorbs moisture from the air resulting in a
lower boiling point. This may cause it to boil
unexpectedly during hard or prolonged
braking, resulting in sudden brake failure. This
could result in a collision.
Overfilling the brake fluid reservoir can result
in spilling brake fluid on hot engine parts,
causing the brake fluid to catch fire. Brake
fluid can also damage painted and vinyl
surfaces, care should be taken to avoid its
contact with these surfaces.
