Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corrosion
protection and to protect against engine overheating. OAT
coolant (conforming to MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and defroster perfor -
mance, make sure the engine cooling system is functioning
properly and the proper amount, type, and concentration of
coolant is used. Use of the Air Recirculation mode during
Winter months is not recommended, because it may cause
window fogging.
Vacation/Storage
Before 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 fresh air with the
blower setting on high. This will ensure adequate system
lubrication to minimize the possibility of compressor
damage when the system is started again. Window Fogging
Vehicle windows tend to fog on the inside in mild, rainy,
and/or humid weather. To clear the windows, select Defrost
or Mix mode and increase the front blower speed. Do not use
the Recirculation mode without A/C for long periods, as
fogging may occur.
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.

Outside Air Intake
Make sure the air intake, located directly in front of the wind -
shield, is free of obstructions, such as leaves. Leaves collected
in the air intake may reduce airflow, and if they enter the
plenum, they could plug the water drains. In Winter months,
make sure the air intake is clear of ice, slush, and snow.
Cabin Air Filter
The climate control system filters out dust and pollen from
the air. Contact an authorized dealer to service your cabin air
filter, and to have it replaced when needed. Operating Tips Chart

Base / Midline Instrument Cluster Descriptions
1. Tachometer
• Indicates the engine speed in revolutions per minute
(RPM x 1000).
2. Voltmeter
• When the vehicle is in the RUN state, the gauge indi -
cates the electrical system voltage. The pointer should
stay within the normal range if the battery is charged.
If the pointer moves to either extreme left or right and
remains there during normal driving, the electrical
system should be serviced.
3. Instrument Cluster Display
• When the appropriate conditions exist, this display
shows the instrument cluster display messages. Refer
to “Instrument Cluster Display” in “Getting To Know
Your Instrument Panel” for further information. 4. Oil Pressure Gauge
• The pointer should always indicate the oil pressure
when the engine is running. A continuous high or low
reading under normal driving conditions may indicate
a lubrication system malfunction. Immediate service
should be obtained from an authorized dealer.
NOTE:
In vehicles equipped with Stop/Start, an oil pressure indica -
tion of zero is normal during an Autostop.
5. Speedometer
• Indicates vehicle speed.

6. Fuel Gauge
• The pointer shows the level of fuel in the fuel tank
when the ignition is in the ON/RUN position.
• The fuel pump symbol points to the side of the
vehicle where the fuel door is located.
7. Temperature Gauge
• The gauge pointer shows engine coolant temperature.
The pointer positioned within the normal range indi -
cates that the engine cooling system is operating satis -
factorily.
• 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. 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 “Servicing And Maintenance.” Follow the
warnings under the Cooling System Pressure Cap
paragraph.
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,” turn
the engine off immediately and call an authorized dealer
for service. 3

INSTRUMENT CLUSTER DISPLAY
Your vehicle will be equipped with an instrument cluster
display, which offers useful information to the driver. With
the ignition in the STOP/OFF mode, opening/closing of a
door will activate the display for viewing, and display the
total miles, or kilometers, in the odometer. Your instrument
cluster display is designed to display important information
about your vehicle’s systems and features. Using a driver
interactive display located on the instrument panel, your
instrument cluster display can show you how systems are
working and give you warnings when they are not. The
steering wheel mounted controls allow you to scroll through
the main menus and submenus. You can access the specific
information you want and make selections and adjustments. Instrument Cluster Display Controls
The instrument cluster display features a driver-interactive
display that is located in the instrument cluster.
