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 298.
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.
Windshield Wiper De-Icer — If Equipped
The windshield wiper de-icer is a heating element
located at the base of the windshield.
It operates automatically once the following
conditions are met:
Activation By Front Defrost
The wiper de-icer activates automatically during
a cold weather manual start with full defrost,
and when the ambient temperature is below
33°F (0.6°C) .
Activation By Rear Defrost
The wiper de-icer activates automatically when
the Rear Defrost is operating and the ambient
temperature is below 33°F (0.6°C) .
Activation By Remote Start Operation
When the Remote Start is activated and the
outside ambient temperature is less than 33°F
(0.6°C) the windshield wiper de-icer is acti -
vated. Exiting Remote Start will resume previous
operation. If the windshield wiper de-icer is
active, the timer and operation will continue.

86STARTING AND OPERATING
(Continued)
(Continued)
1–4 SKIP SHIFT
In Auto Drive Mode, Default, or Street Drive Modes,
there are times when you must shift the
transmission directly from FIRST gear to FOURTH
gear instead of from FIRST gear to SECOND gear.
This is to help you get the best possible fuel
economy from your vehicle. This occurs when the
engine coolant (antifreeze) is higher than 106°F
(41°C), vehicle speed is greater than 19 mph
(30 km/h) but less than 21 mph (34 km/h), and
the transmission is in FIRST gear, and the
accelerator is at ¼ throttle or less.
After you shift the transmission to FOURTH gear,
you can press the clutch in and shift to another
forward gear.
DOWNSHIFTING
To maintain a safe speed and prolong brake life,
downshift to maintain a safe speed when
descending a steep grade.
AUTOMATIC TRANSMISSION —
IF EQUIPPED
You must press and hold the brake pedal while
shifting out of PARK.
WARNING!
Skipping more than one gear while downshifting,
could cause you to lose control of your vehicle.
You could have a collision.
CAUTION!
If you skip more than one gear while down -
shifting or downshift at too high an engine
speed, you could damage the engine, trans -
mission, or clutch.

Do not downshift into FIRST gear when the
vehicle is moving faster than 15 mph
(24 km/h), as you could damage the engine
and/or clutch.

WARNING!
Never use the PARK position as a substitute
for the parking brake. Always apply the
parking brake fully when exiting the vehicle to
guard against vehicle movement and possible
injury or damage.
Your vehicle could move and injure you and
others if it is not in PARK. Check by trying to
move the transmission gear selector out of
PARK with the brake pedal released. Make
sure the transmission is in PARK before
exiting the vehicle.
The transmission may not engage PARK if the
vehicle is moving. Always bring the vehicle to a
complete stop before shifting to PARK, and
verify that the transmission gear position indi -
cator solidly indicates PARK (P) without
blinking. Ensure that the vehicle is completely
stopped, and the PARK position is properly
indicated, before exiting the vehicle.
It is dangerous to shift out of PARK or
NEUTRAL if the engine speed is higher than
idle speed. If your foot is not firmly pressing
the brake pedal, the vehicle could accelerate
quickly forward or in reverse. You could lose
control of the vehicle and hit someone or
something. Only shift into gear when the
engine is idling normally and your foot is firmly
pressing the brake pedal.

PERIODIC SAFETY CHECKS YOU SHOULD
M
AKE OUTSIDE THE VEHICLE
Tires
Examine tires for excessive tread wear and uneven
wear patterns. Check for stones, nails, glass, or
other objects lodged in the tread or sidewall.
Inspect the tread for cuts and cracks. Inspect
sidewalls for cuts, cracks, and bulges. Check the
lug nuts/bolt torque for tightness. Check the tires
(including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight
parking for fuel, 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.
EXHAUST GAS
The best protection against carbon monoxide entry
into the vehicle body is a properly maintained
engine exhaust system.
Whenever a change is noticed in the sound of the
exhaust system, when exhaust fumes can be
detected inside the vehicle, or when the underside
or rear of the vehicle is damaged, have an authorized dealer inspect the complete exhaust
system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts.
Open seams or loose connections could permit
exhaust fumes to seep into the passenger
compartment. In addition, inspect the exhaust
system each time the vehicle is raised for
lubrication or oil change. Replace as required.
CARBON MONOXIDE WARNINGS
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you
unconscious and can eventually poison you. To
avoid breathing (CO), follow these safety tips:
Do not run the engine in a closed garage or in
confined areas any longer than needed to
move your vehicle in or out of the area.
If you are required to drive with the trunk/lift
-
gate/rear doors open, make sure that all
windows are closed and the climate control
BLOWER switch is set at high speed. DO NOT
use the recirculation mode.
If it is necessary to sit in a parked vehicle with
the engine running, adjust your heating or
cooling controls to force outside air into the
vehicle. Set the blower at high speed.
WARNING!
Carbon monoxide (CO) in exhaust gases is
deadly. Follow the precautions below to prevent
carbon monoxide poisoning:

Do not inhale exhaust gases. They contain
carbon monoxide, a colorless and odorless gas,
which can kill. Never run the engine in a closed
area, such as a garage, and never sit in a parked
vehicle with the engine running for an extended
period. If the vehicle is stopped in an open area
with the engine running for more than a short
period, adjust the ventilation system to force
fresh, outside air into the vehicle.

Guard against carbon monoxide with proper
maintenance. Have the exhaust system
inspected every time the vehicle is raised.
Have any abnormal conditions repaired
promptly. Until repaired, drive with all side
windows fully open.
