50GETTING TO KNOW YOUR VEHICLE
Winter Operation
To ensure the best possible heater and defroster
performance, 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
For information on maintaining the Climate Control system
when the vehicle is being stored for an extended period of
time, see
Úpage 261.
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.
Outside Air Intake
Make sure the air intake, located directly in front of the
windshield, is free of obstructions, such as leaves. Leaves
collected in the air intake may reduce airflow, and if they
enter the air distribution box, 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.

218IN CASE OF EMERGENCY
IF YOUR ENGINE OVERHEATS
If the vehicle is overheating, it will need to be serviced by
an authorized dealer.
Potential signs of vehicle overheating:
Temperature gauge is at HOT (H)
 Strong smell of coolant
 White smoke coming from engine or exhaust
 Coolant bottle coolant has bubbles present If the temperature gauge is moving towards or close to the
HOT (H) position, you can reduce the potential for
overheating by taking the appropriate action.

On 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.
 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.
GEAR SELECTOR OVERRIDE
If a malfunction occurs, and the gear selector cannot be
moved out of the PARK position, you can use the following
procedure to temporarily move the gear selector:

1. First turn the engine OFF.

2. Apply the parking brake.
3. Grab the boot material of the gear selector and pull up to carefully separate the gear selector bezel and
boot assembly from the center console.

Gear Selector Bezel

4. Press and maintain firm pressure on the brake pedal.
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.
CAUTION!
Driving with a hot 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 for service.

SERVICING AND MAINTENANCE
SCHEDULED SERVICING
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate in the instrument cluster.
This means that service is required for your vehicle.
Operating conditions such as frequent short-trips, trailer
towing, and extremely hot or cold ambient temperatures
will influence when the “Change Oil” or “Oil Change
Required” message is displayed. Have your vehicle
serviced as soon as possible, within the next 500 miles
(805 km).An authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a
scheduled oil change is performed by someone other than
an authorized dealer, the message can be reset by
referring to the steps described under Instrument Cluster
Display
Úpage 66.
NOTE:Under no circumstances should oil change intervals
exceed 10,000 miles (16,000 km), one year or 350 hours
of engine run time, whichever comes first. The 350 hours
of engine run or idle time is generally only a concern for
fleet customers.
Once A Month Or Before A Long Trip:

Check engine oil level.
 Check windshield washer fluid level.
 Check the tire inflation pressures and look for unusual
wear or damage. Rotate tires at the first sign of irreg -
ular wear, even if it occurs before the oil indicator
system turns on.
 Check the fluid levels of the coolant reservoir, and
brake master cylinder reservoir, and fill as needed.
 Check function of all interior and exterior lights.
