Flowing/Rising Water
Shallow Standing Water
Although your vehicle is capable of driving through shallow
standing water, consider the following Cautions and Warn-
ings before doing so.
WARNING!
Do not drive on or across a road or path where water is
flowing and/or rising (as in storm run-off). Flowing
water can wear away the road or path's surface and cause
your vehicle to sink into deeper water. Furthermore,
flowing and/or rising water can carry your vehicle away
swiftly. Failure to follow this warning may result in
injuries that are serious or fatal to you, your passengers,
and others around you.
WARNING!
• Driving through standing water limits your vehicle’s traction capabilities. Do not exceed 5 mph (8 km/h)
when driving through standing water.
• Driving through standing water limits your vehicle’sbraking capabilities, which increases stopping
distances. Therefore, after driving through standing
water, drive slowly and lightly press on the brake pedal
several times to dry the brakes.
• Failure to follow these warnings may result in injuries that are serious or fatal to you, your passengers, and
others around you.
CAUTION!
• Always check the depth of the standing water before driving through it. Never drive through standing water
that is deeper than the bottom of the tire rims mounted
on the vehicle.
• Determine the condition of the road or the path that is under water and if there are any obstacles in the way
before driving through the standing water.
• Do not exceed 5 mph (8 km/h) when driving through standing water. This will minimize wave effects.
WARNING! (Continued)

• After extended operation in mud, sand, water, or similardirty conditions, have the radiator, fan, brake rotors,
wheels, brake linings, and axle yokes inspected and
cleaned as soon as possible. • If you experience unusual vibration after driving in mud,
slush or similar conditions, check the wheels for impacted
material. Impacted material can cause a wheel imbalance
and freeing the wheels of it will correct the situation.
WARNING!
Abrasive material in any part of the brakes may cause
excessive wear or unpredictable braking. You might not
have full braking power when you need it to prevent a
collision. If you have been operating your vehicle in
dirty conditions, get your brakes checked and cleaned as
necessary.

STARTING AND OPERATING

IN CASE OF EMERGENCY 475
If frequent jump starting is required to start your vehicle you
should have the battery and charging system inspected at an
authorized dealer.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the poten-
tial 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. 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.
CAUTION!
Accessories plugged into the vehicle power outlets draw
power from the vehicle’s battery, even when not in use
(i.e., cellular devices, etc.). Eventually, if plugged in long
enough without engine operation, the vehicle’s battery
will discharge sufficiently to degrade battery life and/or
prevent the engine from starting.
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.6

512 SERVICING AND MAINTENANCE
• If frequent engine coolant (antifreeze) additions arerequired, the cooling system should be pressure tested for
leaks.
• Maintain engine coolant (antifreeze) concentration at a minimum of 50% OAT coolant (conforming to MS.90032)
and distilled water for proper corrosion protection of your
engine which contains aluminum components.
• 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 oper -
ation. If replacement is ever necessary, install ONLY the
correct type thermostat. Other designs may result in unsat -
isfactory engine coolant (antifreeze) performance, poor
gas mileage, and increased emissions.
Brake System
In order to ensure brake system performance, all brake
system components should be inspected periodically. Refer
to the “Maintenance Plan” in this section for the proper
maintenance intervals. Fluid Level Check — Brake Master Cylinder
The fluid level of the master cylinder should be checked
when performing under the hood service or immediately if
the brake system warning lamp indicates system failure.
If necessary, add fluid to bring level within the designated
marks on the side of the reservoir of the brake master
cylinder. Be sure to clean the top of the master cylinder area
before removing cap.
With disc brakes the fluid level can be expected to fall as the
brake linings wear. However, an unexpected drop in fluid
level may be caused by a leak and a system check should be
conducted.
Refer to “Fluids And Lubricants” in “Technical Specifica
-
tions” for further information.
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.

SERVICING AND MAINTENANCE 535
Wheel And Wheel Trim Care
All wheels and wheel trim, especially aluminum and chrome
plated wheels, should be cleaned regularly using mild
(neutral Ph) soap and water to maintain their luster and to
prevent corrosion. Wash wheels with the same soap solution
recommended for the body of the vehicle and remember to
always wash when the surfaces are not hot to the touch.
Your wheels are susceptible to deterioration caused by salt,
sodium chloride, magnesium chloride, calcium chloride, etc.,
and other road chemicals used to melt ice or control dust on
dirt roads. Use a soft cloth or sponge and mild soap to wipe
away promptly. Do not use harsh chemicals or a stiff brush.
They can damage the wheel’s protective coating that helps
keep them from corroding and tarnishing.When cleaning extremely dirty wheels including excessive
brake dust, care must be taken in the selection of tire and
wheel cleaning chemicals and equipment to prevent damage
to the wheels. Mopar Wheel Treatment or Mopar Chrome
Cleaner or their equivalent is recommended or select a
non-abrasive, non-acidic cleaner for aluminum or chrome
wheels.
NOTE:
If you intend parking or storing your vehicle for an extended
period after cleaning the wheels with wheel cleaner, drive
your vehicle and apply the brakes to remove the water drop
-
lets from the brake components. This activity will remove the
red rust on the brake rotors and prevent vehicle vibration
when braking.
CAUTION!
Avoid products or automatic car washes that use acidic
solutions or strong alkaline additives or harsh brushes.
Many aftermarket wheel cleaners and automatic car
washes may damage the wheel's protective finish. Such
damage is not covered by the New Vehicle Limited
Warranty. Only car wash soap, Mopar Wheel Cleaner or
equivalent is recommended.
CAUTION!
Do not use scouring pads, steel wool, a bristle brush,
metal polishes or oven cleaner. These products may
damage the wheel's protective finish. Such damage is not
covered by the New Vehicle Limited Warranty. Only car
wash soap, Mopar Wheel Cleaner or equivalent is
recommended.

TECHNICAL SPECIFICATIONS
IDENTIFICATION DATA
Vehicle Identification Number
The Vehicle Identification Number (VIN) is found on the left
front corner of the instrument panel, visible through the
windshield. This number also appears on the vehicle frame
etched on right hand center rail, as well as the Automobile
Information Disclosure Label affixed to a window on your
vehicle, the vehicle registration and title.Vehicle Identification Number
NOTE:
It is illegal to remove or alter the VIN.
BRAKE SYSTEM
If power assist is lost for any reason (for example, repeated
brake applications with the engine off), the brakes will still
function. However, you will experience a substantial
increase in braking effort to stop the vehicle.
If either the front or rear hydraulic system loses normal
braking capability, the remaining system will still function
with some loss of overall braking effectiveness. This will be
evident by increased pedal travel during application, greater
pedal force required to slow or stop, and activation of the
“Brake Warning Light” and the “ABS Warning Light” (if
equipped) during brake use.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure that
the wheel is properly mounted to the vehicle. Any time a
wheel has been removed and reinstalled on the vehicle, the
lug nuts/bolts should be torqued using a properly calibrated
torque wrench using a high quality six sided (hex) deep wall
socket.
