If the light remains lit with the engine running, your
vehicle will usually be drivable. However, see an autho-
rized dealer for service as soon as possible. If the light is
flashing when the engine is running, immediate service is
required. You may experience reduced performance, an
elevated/rough idle or engine stall and your vehicle may
require towing.
•Engine Temperature Warning Light
This light warns of an overheated engine condi-
tion. As temperatures rise and the gauge ap-
proaches H,this indicator will illuminate and a single
chime will sound after reaching a set threshold. Further
overheating will cause the temperature gauge to pass H,
a continuous chime will occur until the engine is allowed
to cool.
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 ve-
hicle. If the temperature reading does not return to
normal, turn the engine off immediately and call for
service. Refer to “If Your Engine Overheats” in “What To
Do In Emergencies” for further information.
NOTE:
When the transmission is shifted to Neutral,
activate the parking brake to prevent the vehicle from
rolling away.
• Electric Power Steering Malfunction Warning Light
This telltale is on when the Electric Power
Steering is not operating and needs service.
• Trailer Brake Disconnected Warning Light
This telltale is on when the Trailer Brake has
been disconnected.

CLIMATE CONTROLS
The Climate Control System allows you to regulate the
temperature, amount, and direction of air circulating
throughout the vehicle. The controls are located on the
instrument panel below the radio.
Manual Climate Controls Without Touchscreen —
If Equipped
The controls for the manual heating and air conditioning
system in this vehicle consist of a series of outer rotary
dials and inner push knobs. These comfort controls can
be set to obtain desired interior conditions.Manual Climate Controls

5. Defrost Button
Press and release this button to turn on the rear window
defroster (if equipped) and the heated outside mirrors (if
equipped). An indicator will illuminate when the rear
window defroster is on. The rear window defroster
automatically turns off after 10 minutes.
CAUTION!
Failure to follow these cautions can cause damage to
the heating elements:
•Use care when washing the inside of the rear
window. Do not use abrasive window cleaners on
the interior surface of the window. Use a soft cloth
and a mild washing solution, wiping parallel to the
heating elements. Labels can be peeled off after
soaking with warm water.

•Do not use scrapers, sharp instruments, or abrasive
window cleaners on the interior surface of the
window.
• Keep all objects a safe distance from the window.
6. Modes
The airflow distribution mode can be adjusted so air
comes from the instrument panel outlets, floor outlets,
and demist outlets. The Mode settings are as follows: •Panel Mode
Air comes from the outlets in the instrument
panel. Each of these outlets can be individu-
ally adjusted to direct the flow of air. The air
vanes of the center outlets and outboard outlets can
be moved up and down or side to side to regulate
airflow direction. There is a shut off wheel located
below the air vanes to shut off or adjust the amount
of airflow from these outlets.

5. Front Defrost Button
Press and release to change the current airflow setting to
Defrost mode. The indicator illuminates when this fea-
ture is ON. Air comes from the windshield and side
window demist outlets. When the defrost button is
selected, the blower level will increase. Use Defrost mode
with maximum temperature settings for best windshield
and side window defrosting and defogging. Performing
this function will cause the ATC to switch into manual
mode. If the front defrost mode is turned off the climate
system will return the previous setting.
6. Defrost Button
Press and release this button to turn on the rear window
defroster (if equipped) and the heated outside mirrors (if
equipped). An indicator will illuminate when the rear
window defroster is on. The rear window defroster
automatically turns off after 10 minutes.CAUTION!

The blower fan speed can be set to any fixed speed by
adjusting the blower control. The fan will now operate at
a fixed speed until additional speeds are selected. This
allows the front occupants to control the volume of air
circulated in the vehicle and cancel the Auto mode.
The operator can also select the direction of the airflow
by selecting one of the available mode settings. A/C
operation and Recirculation control can also be manually
selected in Manual operation.
NOTE:Each of these features operates independently
from each other. If any feature is controlled manually,
temperature control will continue to operate automati-
cally.
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.
OAT coolant (conforming to MS.90032) is recommended.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for proper coolant selection.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is function-
ing properly and the proper amount, type, and concen-
tration of coolant is used. Refer to “Maintenance
Procedures” in “Maintaining Your Vehicle” for proper
coolant selection. Use of the air Recirculation mode
during Winter months is not recommended because it
may cause window fogging.

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belt.
The starter should not be operated for more than 10-
second intervals. Waiting a few seconds between such
intervals will protect the starter from overheating.
WARNING!
•Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Leaving children in
a vehicle unattended is dangerous for a number of
reasons. A child or others could be seriously or
fatally injured. Children should be warned not to
touch the parking brake, brake pedal or the gear
selector.
(Continued)
WARNING! (Continued)
•Do not leave the Key Fob in or near the vehicle, or
in a location accessible to children, and do not
leave the ignition of a vehicle equipped with
Keyless Enter-N-Go in the ACC or ON/RUN mode.
A child could operate power windows, other con-
trols, or move the vehicle.
Normal Starting
Normal starting of either a warm or cold engine is
obtained without pumping or pressing the accelerator
pedal. Cycle the ignition to the START position and
release when the engine starts. If the engine fails to start
within 10 seconds, cycle the ignition to the OFF position,
wait five seconds, then repeat the “Normal Starting”
procedure.
442 STARTING AND OPERATING

Autostop, the Climate Controls system may automati-
cally adjust airflow to maintain cabin comfort. Customer
settings will be maintained upon return to an engine
running condition.
Possible Reasons The Engine Does Not Autostop
Prior to engine shut down, the system will check many
safety and comfort conditions to see if they are fulfilled.
In following situations the engine will not stop:
•Driver ’s seat belt is not buckled
• Driver ’s door is not closed
• Outside temperature is less than 1°F (–17°C) or greater
than 104°F (40°C)
• Battery temperature too warm or cold
• The vehicle is on a steep grade •
Cabin heating or cooling is in process and an accept-
able cabin temperature has not been achieved
• HVAC is set to full defrost mode at a high blower
speed
• Engine has not reached normal operating temperature
• Battery discharged
• The transmission is not in DRIVE
• Hood is open
• Vehicle is in 4LO transfer case mode
Other factors which can inhibit AutoStop include: fuel
level, accelerator pedal input, engine temp too high and
steering angle.
It may be possible for the vehicle to be driven several
times without the STOP/START system going into a
STOP/START READY state under more extreme condi-
tions of the items listed above.
