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.
WARNING!
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 acceler -
ator, 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.
 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.

IF YOUR ENGINE OVERHEATS
If the vehicle is overheating, it will need to be serviced by
an authorized dealer.
Potential signs of vehicle overheating can be:
Temperature gauge is at HOT (H)
 Strong smell of coolant
 White smoke coming from engine or exhaust
 Coolant bottle coolant has bubbles present In the event it is observed that the temperature gauge is
moving towards or close to the HOT (H) position, you can
reduce the potential for overheating by taking the
appropriate action.

On the highways — slow down.
 In city traffic — while stopped, place the transmission in
NEUTRAL (N), but do not increase the engine idle speed
while preventing vehicle motion with the brakes.
 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 supple -
ment to the radiator and aids in removing heat from the
engine cooling system.
MANUAL PARK RELEASE
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.
WARNING!
 Never have any smoking materials lit in or near the
vehicle when the fuel door is open or the tank is
being filled.
 Never add fuel when the engine is running. This is in
violation of most state and federal fire regulations
and may cause the Malfunction Indicator Light to
turn on.
 A fire may result if fuel is pumped into a portable
container that is inside of a vehicle. You could be
burned. Always place fuel containers on the ground
while filling.
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), as
soon as it’s safe, 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!
You should be seated in the driver’s seat with your foot
firmly placed on the brake pedal to maintain control of
the vehicle before activating the Manual Park Release.
If possible, you should apply the parking brake.
Activating the Manual Park Release will allow your
vehicle to roll away if it is not secured or properly
connected 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.

TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled vehicle using a commercial towing service.
If the transmission and drivetrain are operable, disabled 4x4 vehicles may also be towed as described on
Úpage 190.
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 manufacturer’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 fascia/bumpers or associated brackets. State
and local laws regarding vehicles under tow must be observed.
NOTE:Vehicle’s equipped with air suspension, must have Tire Jack Mode Úpage 215 enabled to prevent air suspension movement during towing.
If you must use the accessories (wipers, defrosters, etc.) while being towed, the ignition must be in the ON/RUN mode.
If the vehicle's battery is discharged, instructions on shifting the automatic transmission out of PARK (P) in order to move the vehicle

SERVICING AND MAINTENANCE
SCHEDULED SERVICING
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that service
is required for your vehicle. Operating conditions such as
frequent short-trips, trailer tow, extremely hot or cold
ambient temperatures, and extended idling will influence
when the “Oil Change Required” message is displayed.
Have your vehicle serviced as soon as possible, within the
next 500 miles (805 km).An authorized dealer will reset the oil change indicator
message after completing the scheduled oil change or for
engine oil life reset procedure Úpage 101.
NOTE:3.0L & 5.7L Engines:
Under no circumstances should oil
change intervals exceed 10,000 miles (16,000 km), or
12 months, whichever comes first. The engine controller
also monitors the number of hours of engine run time, and
will illuminate the oil change indicator after 350 hours
(which is not likely to be exceeded except for certain fleet
customers with extended engine idling periods).
6.4L Engines: Under no circumstances should oil change
intervals exceed 6,000 miles (10,000 km), or 6 months,
whichever comes first. The engine controller also monitors
the number of hours of engine run time, and will illuminate
the oil change indicator after 350 hours (which is not likely
to be exceeded except for certain fleet customers with
extended engine idling periods). Once A Month Or Before A Long Trip:

Check engine oil level
 Check windshield washer fluid level
 Check the tire inflation pressures and look for unusual
wear or damage
 Check the fluid levels of the coolant reservoir, brake
master cylinder and fill as needed.
 Check function of all interior and exterior lights
