VEHICLE SECURITY ALARM —
IF EQUIPPED
The Vehicle Security Alarm monitors the hood,
liftgate, liftgate flipper glass, vehicle doors for
unauthorized entry, and the ignition switch for
unauthorized operation. If something triggers
the alarm, the Vehicle Security Alarm will pre-
vent the vehicle from starting and provide the
following audio and visual signals: the horn will
pulse, the headlights will flash, the park lights
will flash, and the Vehicle Security Light in the
instrument cluster will flash.
To Arm the System
Vehicles Not Equipped with Keyless
Enter-N-Go
Remove the key from the ignition switch and
either press a power door lock switch while the
driver or passenger door is open, or press the
LOCK button on the Remote Keyless Entry
(RKE) transmitter. After the last door is closed,
or if all doors are closed, the Vehicle Security
Alarm will arm itself in about 16 seconds.
During that time, the Vehicle Security Light will
flash. If it does not illuminate, the Vehicle Secu-
rity Alarm is not arming. Also, if you open a door
during the arming period, the Vehicle Security
Alarm will cancel the arming process. If you
wish to rearm the Vehicle Security Alarm after
closing the door, you must repeat one of the
previously-described arming sequences.

0.3 in (8 mm) forward of the rear stop if the
starting position is between 0.9 to 2.67 in (23
to 68 mm) forward of the rear stop when the
key is removed from the ignition switch. The
seat will move forward to the memory/driving
position when the key is placed into the
ignition, and turned out of the LOCK position
toward the ACC/ON position.
The Easy Entry/Exit feature will be automatically
disabled if the seat is already positioned closer
than 0.9 in (23 mm) forward of the rear stop. At
this position, there is no benefit to the driver by
moving the seat for Easy Exit/Entry.
Each stored memory setting will have an asso-
ciated Easy Entry/Exit position.
NOTE:
The Easy Entry/Exit feature is not enabled
when the vehicle is delivered from the fac-
tory. The Easy Entry/Exit feature is enabled
(or later disabled) through the programmable
features in the Electronic Vehicle Information
Center (EVIC). Refer to “Electronic Vehicle

WARNING!
Be sure the hood is fully latched before driving
your vehicle. If the hood is not fully latched, it
could open when the vehicle is in motion and
block your vision. Failure to follow this warn-
ing could result in serious injury or death.
LIGHTS
Headlight Switch
The headlight switch is located on the left side
of the instrument panel, next to the steering
wheel. The headlight switch controls the opera-
tion of the headlights, parking lights, instrument
panel lights, cargo lights and fog lights (if
equipped).To turn on the headlights, rotate
the headlight switch clockwise.
When the headlight switch is on
the parking lights, taillights, li-
cense plate light and instrument
panel lights are also turned on. To
turn off the headlights, rotate the headlight
switch back to the O (Off) position.
NOTE:
• Your vehicle is equipped with plastic
headlight and fog light (if equipped)
lenses that are lighter and less suscep-
tible to stone breakage than glass lights. Plastic is not as scratch resistant as glass
and therefore different lens cleaning pro-
cedures must be followed.
• To minimize the possibility of scratching
the lenses and reducing light output,
avoid wiping with a dry cloth. To remove
road dirt, wash with a mild soap solution
followed by rinsing.
CAUTION!
Do not use abrasive cleaning components,
solvents, steel wool or other abrasive materi-
als to clean the lenses.
Automatic Headlights — If EquippedThis system automatically turns the headlights
on or off according to ambient light levels. To
turn the system on, rotate the headlight switch
to the A (AUTO) position.
When the system is on, the Headlight Delay
feature is also on. This means the headlights
will stay on for up to 90 seconds after you turn
the ignition switch to the OFF position. To turn
the automatic headlights off, turn the headlight
switch out of the AUTO position.

NOTE:
Broken, muddy, or obstructed headlights
and taillights of vehicles in the field of view
will cause headlights to remain on longer
(closer to the vehicle). Also, dirt, film, and
other obstructions (sticker, toll box, etc.) on
the windshield or camera lens will cause the
system to function improperly.
Daytime Running Lights —
If Equipped
The Daytime Running Lights (low intensity)
come on whenever the engine is running, and
the transmission is not in the PARK position.
The lights will remain on until the ignition is
switched to the OFF or ACC position or the
parking brake is engaged. The headlight
switch must be used for normal nighttime driv-
ing.
Disabling the Daytime Running Lights
To disable the Daytime Running Lights open
the hood and located the Power Distribution
Center (PDC), located on the right side of the
engine compartment.Open the PDC by pulling outward on the lock-
ing tabs (one on each side) and pulling upward
on the cover.Remove the left and right Daytime Running
Lamp relays and reinstall the PDC cover.
Automatic Headlight Leveling — HID
Headlights Only
This feature prevents the headlights from inter-
fering with the vision of oncoming drivers.

HAZARD WARNING FLASHERSThe Hazard Warning flasher switch is located
on the switch bank just above the climate
controls.Press the switch to turn on the Hazard
Warning flasher. When the switch is
activated, all directional turn signals will
flash on and off to warn oncoming
traffic of an emergency. Press the switch a
second time to turn off the Hazard Warning
flasher.
This is an emergency warning system and it
should not be used when the vehicle is in
motion. Use it when your vehicle is disabled
and it is creating a safety hazard for other
motorists.
When you must leave the vehicle to seek assis-
tance, the Hazard Warning flasher will continue
to operate even though the ignition is placed in
the OFF position.
NOTE:
With extended use the Hazard Warning
flasher may wear down your battery.IF YOUR ENGINE OVERHEATSIn any of the following situations, 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, but do not in-
crease the engine idle speed.
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 supple-
ment to the radiator and aids in removing
heat from the engine cooling system.CAUTION!
Driving with a hot cooling system could dam-
age 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!
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.
258

WARNING!
•Take care to avoid the radiator cooling fan
whenever the hood is raised. It can start
anytime the ignition switch is on. You can
be injured by moving fan blades.
• Remove any metal jewelry such as watch
bands or bracelets that might make an
inadvertent electrical contact. You could be
seriously injured.
• Batteries contain sulfuric acid that can burn
your skin or eyes and generate hydrogen
gas which is flammable and explosive.
Keep open flames or sparks away from the
battery.
1. Set the parking brake, shift the automatic
transmission into PARK and turn the ignition to
LOCK.
2. Turn off the heater, radio, and all unneces-
sary electrical accessories.
3. Remove the protective cover over the re-
mote positive (+)battery post. Pull upward on
the cover to remove it. 4. If using another vehicle to jump-start the
battery, park the vehicle within the jumper
cables reach, set the parking brake and make
sure the ignition is OFF.
WARNING!
Do not allow vehicles to touch each other as
this could establish a ground connection and
personal injury could result.
Jump-Starting Procedure
WARNING!
Failure to follow this procedure could result in
personal injury or property damage due to
battery explosion.
CAUTION!
Failure to follow these procedures could result
in damage to the charging system of the
booster vehicle or the discharged vehicle.
1. Connect the positive
(+)end of the jumper
cable to the remote positive (+)post of the
discharged vehicle.
2. Connect the opposite end of the positive (+)
jumper cable to the positive (+)post of the
booster battery.
3. Connect the negative end (-)of the jumper
cable to the negative (-)post of the booster
battery.
4. Connect the opposite end of the negative (-)
jumper cable to the remote negative (-)post of
the vehicle with the discharged battery.
WARNING!
Do not connect the cable to the negative post
(-) of the discharged battery. The resulting
electrical spark could cause the battery to
explode and could result in personal injury.
5. Start the engine in the vehicle that has the
booster battery, let the engine idle a few min-
utes, and then start the engine in the vehicle
with the discharged battery.
263

attention should also be given to hood latching
components to ensure proper function. When
performing other underhood services, the hood
latch, release mechanism and safety catch
should be cleaned and lubricated.
The external lock cylinders should be lubri-
cated twice a year, preferably in the Fall and
Spring. Apply a small amount of a high quality
lubricant, such as MOPARLock Cylinder Lu-
bricant or equivalent directly into the lock cyl-
inder.
Windshield Wiper BladesClean the rubber edges of the wiper blades
and the windshield periodically with a sponge
or soft cloth and a mild nonabrasive cleaner to
remove accumulations of salt or road film.
Operation of the wipers on dry glass for long
periods may cause deterioration of the wiper
blades. Always use washer fluid when using
the wipers to remove salt or dirt from a dry
windshield.
Avoid using the wiper blades to wipe frost or
ice from the windshield. Keep the blade rubber
out of contact with petroleum products such as
engine oil, gasoline, etc. NOTE:
Life expectancy of wiper blades varies de-
pending on geographical area and fre-
quency of use. Poor performance of blades
may be present with chattering, marks, wa-
ter lines or wet spots. If any of these condi-
tions are present, clean the wiper blades or
replace as necessary.
Adding Washer FluidThe fluid reservoir for the windshield washers
and the rear window washer is shared. The fluid
reservoir is located in the engine compartment,
be sure to check the fluid level at regular
intervals. Fill the reservoir with windshield
washer solvent only (not radiator antifreeze).
When refilling the washer fluid reservoir, take
some washer fluid and apply it to a cloth or
towel and wipe clean the wiper blades, this will
help blade performance. To prevent freeze-up
of your windshield washer system in cold
weather, select a solution or mixture that meets
or exceeds the temperature range of your cli-
mate. This rating information can be found on
most washer fluid containers.
WARNING!
Commercially available windshield washer
solvents are flammable. They could ignite and
burn you. Care must be exercised when filling
or working around the washer solution.
Exhaust SystemThe best protection against carbon monoxide
entry into the vehicle body is a properly main-
tained engine exhaust system.
If you notice a change in the sound of the
exhaust system; or if the exhaust fumes can be
detected inside the vehicle; or when the under-
side or rear of the vehicle is damaged; have an
authorized technician inspect the complete ex-
haust system and adjacent body areas for
broken, damaged, deteriorated, or misposi-
tioned 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.
278

•Do not idle the engine with any spark plug
wires disconnected or removed, such as
when diagnostic testing, or for prolonged
periods during very rough idle or malfunc-
tioning operating conditions.
Cooling System
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.
Engine Coolant Checks
Check the engine coolant (antifreeze) protec-
tion every 12 months (before the onset of
freezing weather, where applicable). If the en-
gine coolant (antifreeze) is dirty or rusty in
appearance, the system should be drained,
flushed and refilled with fresh engine coolant
(antifreeze). Check the front of the A/C con-
denser for any accumulation of bugs, leaves, etc. If dirty, clean by gently spraying water from
a garden hose vertically down the face of the
condenser.
Check the engine cooling system hoses for
brittle rubber, cracking, tears, cuts, and tight-
ness of the connection at the coolant recovery
bottle and radiator. Inspect the entire system
for leaks.
With the engine at normal operating tempera-
ture (but not running), check the cooling sys-
tem pressure cap for proper vacuum sealing by
draining a small amount of engine coolant
(antifreeze) from the radiator drain cock. If the
cap is sealing properly, the engine coolant
(antifreeze) will begin to drain from the coolant
recovery bottle. DO NOT REMOVE THE COOL-
ANT PRESSURE CAP WHEN THE COOLING
SYSTEM IS HOT.
Cooling System – Drain, Flush, and Refill
If the engine coolant (antifreeze) is dirty and
contains a considerable amount of sediment,
clean and flush with reliable cooling system
cleaner. Follow with a thorough rinsing to re-
move all deposits and chemicals. Properly dis-
pose of the old engine coolant (antifreeze).
Refer to the “Maintenance Schedule” for the
proper maintenance intervals.
Selection Of Coolant
Use only the manufacturer’s recommended en-
gine coolant (antifreeze). Refer to “Fluids, Lu-
bricants, and Genuine Parts” in “Maintaining
Your Vehicle” for further information.CAUTION!
•
Mixing of engine coolant (antifreeze), other
than the specified HOAT engine coolant
(antifreeze), may result in engine damage
and may decrease corrosion protection. If a
non-HOAT engine coolant (antifreeze) is
introduced into the cooling system in an
emergency, it should be replaced with the
specified engine coolant (antifreeze) as
soon as possible.

•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 nec-
essary, install ONLY the correct type thermo-
stat. Other designs may result in unsatisfac-
tory cooling performance, poor gas mileage,
and increased emissions.
Brake SystemIn order to assure brake system performance,
all brake system components should be peri-
odically inspected. Refer to the “Maintenance
Schedule” for the proper maintenance inter-
vals.
WARNING!
Riding the brakes can lead to brake failure
and possibly an accident. 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. Fluid Level Check – Brake Master Cylinder
The fluid level of the master cylinder should be
checked when performing under the hood ser-
vice, or immediately if the brake system warn-
ing lamp indicates system failure.
The brake master cylinder has a translucent
plastic reservoir. On the outboard side of the
reservoir, there is a “MAX” dot and a “MIN” dot.
The fluid level must be kept within these two
dots. Do not add fluid above the MAX mark,
because leakage may occur at the cap.
With disc brakes, the fluid level can be ex-
pected to fall as the brake linings wear. How-
ever, an unexpected drop in fluid level may be
caused by a leak and a system check should
be conducted.
Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further
information.
WARNING!
•
Use only manufacturer’s recommended
brake fluid. Refer to “Fluids, Lubricants,
and Genuine Parts” in “Maintaining Your
Vehicle” for further information. 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 labeled 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 con-
tainer. 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 sud-
den brake failure. This could result in a
accident.
