Door Latches
Check for positive closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine 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.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 121

16. Fuel Gauge/Fuel Door Reminder
The pointer shows the level of fuel in the fuel tank when
the ignition switch is in the ON/RUN position. The fuel
pump symbol points to the side of the vehicle where the
fuel door is located.
17. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.
The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.
CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge reads
“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 the “H” and you hear continuous chimes,
turn the engine off immediately and call an autho-
rized dealer for service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer
for service if your vehicle overheats. If you decide to
look under the hood yourself, see “Maintaining Your

the vehicle in a high torque converter slip condition,
such as 4-wheel drive operation (e.g., snow plowing,
off- road operation). If this light comes on, stop the
vehicle and run the engine at idle or faster, with the
transmission in NEUTRAL until the light goes off.
CAUTION!
Continuous driving with the Transmission Tempera-
ture Warning Light illuminated will eventually cause
severe transmission damage or transmission failure.
WARNING!
If you continue operating the vehicle when the
Transmission Temperature Warning Light is illumi-
nated you could cause the fluid to boil over, come in
contact with hot engine or exhaust components and
cause a fire.
•Low Coolant Level Indicator
This telltale will turn on to indicate the
vehicle coolant level is low.
•Windshield Washer Fluid Low Indicator
This telltale will turn on to indicate the
windshield washer fluid is low.
•Adaptive Cruise Control (ACC) Malfunction
This light will turn on when a ACC is not
operating and needs service. For further
information, refer to “Adaptive Cruise

and rear wheels to rotate at the same speed. Low range
provides a greater gear reduction ratio to provide in-
creased torque at the wheels.
For further information on four-wheel drive operation
and proper use, refer to “Four-Wheel Drive Operation —
If Equipped” in “Starting And Operating”.
15. SERV 4WD Indicator Light — If Equipped
This light alerts the driver that the 4WD is in need of
service. If this light is illuminated, see your authorized
dealer as soon as possible.
16. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that

ture when driving in hot weather, up mountain grades,

•Loose Fuel Filler Cap Message Indicator
This telltale will turn on to indicate the fuel
filler cap is loose.
13. Odometer Display/Fuel Gauge/Temperature Gauge/
Submenu Area
•The odometer display shows the total distance the
vehicle has been driven.
U.S. Federal regulations require that upon transfer of
vehicle ownership, the seller certify to the purchaser
the correct mileage that the vehicle has been driven. If
your odometer needs to be repaired or serviced, the
repair technician should leave the odometer reading
the same as it was before the repair or service. If s/he
cannot do so, then the odometer must be set at zero,
and a sticker must be placed in the door jamb stating
what the mileage was before the repair or service. It
is a good idea for you to make a record of the
odometer reading before the repair/service, so that
you can be sure that it is properly reset, or that the
door jamb sticker is accurate if the odometer must be
reset at zero.
When the appropriate conditions exist, this display
shows the Driver Information Display (DID) mes-
sages and Submenus.

14. Red Reconfigurable Telltale Display
•Engine Temperature Warning Light
This light warns of an overheated engine
condition. As temperatures rise and the gauge
approachesH,this indicator will illuminate
and a single chime will sound after reaching a set
threshold.
If the light turns on while driving, safely pull over
and stop the vehicle. If the A/C system is on, turn it
off. Also, shift the transmission into NEUTRAL and
idle the vehicle. If the temperature reading does not

Operating Tips
NOTE:Refer to the chart at the end of this section for
suggested control settings for various weather condi-
tions.
Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corro-
sion protection and to protect against engine overheating.
A solution of 50% OAT (Organic Additive Technology)
coolant that meets the requirements of Chrysler Material
Standard MS-12106 and 50% water is recommended.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for proper coolant selection.
Winter Operation
Use of the air Recirculation mode during winter months
is not recommended because it may cause window
fogging.
Vacation Storage
Any time you store your vehicle or keep it out of service
(i.e., vacation) for two weeks or more, run the air
conditioning system at idle for about five minutes in the
fresh air and high blower setting. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.
Window Fogging
Interior fogging on the windshield can be quickly re-
moved by turning the mode selector to Defrost. The
Defrost/Floor mode can be used to maintain a clear
windshield and provide sufficient heating. If side win-
dow fogging becomes objectionable, increase blower
speed to improve airflow and clearing of the side win-
dows. Vehicle windows tend to fog on the inside in mild
but rainy or humid weather.

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.
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.
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.
