sive window cleaners on the interior surface of
the window.
• Keep all objects a safe distance from the window.
Climate Control Functions
A/C (Air Conditioning)
The Air Conditioning (A/C) button allows the operator
to manually activate or deactivate the air conditioning
system. When the air conditioning system is turned on,
cool dehumidified air will flow through the outlets into
the cabin. For improved fuel economy, push the A/C
button to turn off the air conditioning and manually
adjust the blower and airflow mode settings. Also,
make sure to select only Panel, Bi-Level or Floor modes. NOTE:
•
If fog or mist appears on the windshield or side glass,
select Defrost mode and increase blower speed if
needed.
• If your air conditioning performance seems lower
than expected, check the front of the A/C condenser
(located in front of the radiator), for an accumulation
of dirt or insects. Clean with a gentle water spray
from the front of the radiator and through the
condenser.
Recirculation
When outside air contains smoke, odors, or high hu-
midity, or if rapid cooling is desired, you may wish to
recirculate interior air by pushing the Recirculation
control button. The recirculation indicator will illumi-
nate when this button is selected. Push the button a
second time to turn off the Recirculation mode and
allow outside air into the vehicle.

CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the pointer rises to the H (red) mark,
the instrument cluster will sound a chime. When
safe, pull over and stop the vehicle with the engine
at idle. Turn off the air conditioning and wait until
the pointer drops back into the normal range. If the
pointer remains on the H (red) mark for more than
a minute, turn the engine off immediately and call
for service.
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.

WHAT TO DO IN EMERGENCIES 275

MAINTENANCE PROCEDURES
The pages that follow contain therequiredmaintenance
services determined by the engineers who designed
your vehicle.
Besides those maintenance items specified in the fixed
maintenance schedule, there are other components
which may require servicing or replacement in the
future.
CAUTION!
• Failure to properly maintain your vehicle or per-
form repairs and service when necessary could
result in more costly repairs, damage to other
components or negatively impact vehicle perfor-
mance. Immediately have potential malfunctions
examined by an authorized dealer or qualified
repair center.
• Your vehicle has been built with improved fluids
that protect the performance and durability of
your vehicle and also allow extended mainte-
nance intervals. Do not use chemical flushes in
these components as the chemicals can damage
(Continued)
CAUTION! (Continued)
your engine, transmission, or air conditioning.
Such damage is not covered by the New Vehicle
Limited Warranty. If a flush is needed because of
component malfunction, use only the specified
fluid for the flushing procedure.
Engine Oil
Checking Oil Level
To assure proper engine lubrication, the engine oil must
be maintained at the correct level. Check the oil level at
regular intervals, such as every fuel stop. The best time
to check the engine oil level is approximately five
minutes after a fully warmed engine is shut off. Do not
check oil level before starting the engine after it has sat
overnight. Checking engine oil level when the engine is
cold will give you an incorrect reading.
Checking the oil while the vehicle is on level ground,
and approximately five minutes after a fully warmed
engine is shut off, will improve the accuracy of the oil
level readings. Maintain the oil level between the range
markings on the dipstick. The safe range is indicated by
a crosshatch zone. Adding 1 quart (0.9 Liters) of oil
302 MAINTAINING YOUR VEHICLE

Air Conditioner Maintenance
For best possible performance, your air conditioner
should be checked and serviced by an authorized dealer
at the start of each warm season. This service should
include cleaning of the condenser fins and a perfor-
mance test. Drive belt tension should also be checked at
this time.
WARNING!
•Use only refrigerants and compressor lubricants
approved by the manufacturer for your air condi-
tioning system. Some unapproved refrigerants are
flammable and can explode, injuring you. Other
unapproved refrigerants or lubricants can cause
the system to fail, requiring costly repairs. Refer
to Warranty Information Book, located on the
DVD, for further warranty information.
• The air conditioning system contains refrigerant
under high pressure. To avoid risk of personal
injury or damage to the system, adding refriger-
ant or any repair requiring lines to be discon-
nected should be done by an experienced techni-
cian.
CAUTION!
Do not use chemical flushes in your air condition-
ing system as the chemicals can damage your air
conditioning components. Such damage is not cov-
ered by the New Vehicle Limited Warranty.
Refrigerant Recovery And Recycling HFO 1234yf
HFO 1234yf Air Conditioning Refrigerant is a hydro-
fluoolefine HFO that is endorsed by the Environmental
Protection Agency and is an ozone-saving product. The
manufacturer recommends that air conditioning service
be performed by authorized dealer using recovery and
recycling equipment.
NOTE: Use only manufacturer approved A/C system
PAG compressor oil, and refrigerants.
A/C Air Filter
WARNING!
Do not remove the cabin air filter while the vehicle
is running, or while the ignition is in the ACC or
ON/RUN mode. With the cabin air filter removed

306 MAINTAINING YOUR VEHICLE

If an examination of your engine compartment shows
no evidence of radiator or hose leaks, the vehicle may
be safely driven. The vapor will soon dissipate.
•Do not overfill the coolant expansion bottle.
• Check the coolant freeze point in the radiator and in
the coolant expansion bottle. If engine coolant (anti-
freeze) needs to be added, the contents of the coolant
expansion bottle must also be protected against freez-
ing.
• If frequent engine coolant (antifreeze) additions are
required, the cooling system should be pressure
tested for leaks.
• Maintain engine coolant (antifreeze) concentration at
a minimum of 50% OAT coolant (conforming to
MS.90032) and distilled water for proper corrosion
protection of your engine which contains aluminum
components.
• 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 necessary, install
ONLY the correct type thermostat. Other designs may result in unsatisfactory engine coolant (anti-
freeze) performance, poor gas mileage, and increased
emissions.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically.
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure and
possibly a collision. Driving with your foot resting
or riding on the brake pedal can result in abnor-
mally high brake temperatures, excessive lining
wear, and possible brake damage. Riding the
brakes may also reduce braking capacity in an
emergency.
Brake Master Cylinder
The fluid level in the master cylinder should be checked
when performing under hood services, or immediately
if the “Brake Warning Light” is on.

VEHICLE STORAGE
If you will not be using your vehicle for more than 21
days, you may want to take steps to preserve your
battery.
•Disconnect the negative cable from the battery.
• Anytime 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.
NOTE: When the vehicle has not been started or driven
for at least 30 days, an Extended Park Start Procedure is
required to start the vehicle. Refer to “Starting Proce-
dures” in “Starting And Operating” for further infor-
mation.
