Remote Vehicle Start
Your vehicle may have a remote starting feature. This
feature allows you to start the engine from outside of the
vehicle. It also starts up the vehicle’s heating or air
conditioning systems and rear window defogger. When
the remote start system is active and the vehicle
has an automatic climate control system, it will
automatically regulate the inside temperature. Normal
operation of the system will return after the key is turned
to the on position.
Laws in some communities may restrict the use of
remote starters, for example, requiring a person using
remote start to have the vehicle in view when doing so.
Check local regulations for any requirements on
remote starting of vehicles.
Do not use the remote start feature if your vehicle is
low on fuel. Your vehicle may run out of fuel.
/(Remote Start):Press the lock button and then
press this button to use the remote start feature.
To start the vehicle using the remote start feature,
do the following:
1. Aim the transmitter at the vehicle.
2. Press the transmitter’s lock button, release it and
then immediately press and hold the transmitter’s
remote start button until the vehicle’s turn signal
lights ash or for at least four seconds. The
vehicle’s doors will be locked.
3. When the vehicle starts, the parking lamps will turn
on and remain on while the vehicle is running, and
the DIC will display REMOTE START ACTIVE
PRESS HAZARD SWITCH TO CANCEL when the
vehicle starts.
4. If it is your rst remote start since last driving,
repeat these steps while the engine is still
running for a 10 minute time extension.
When you enter the vehicle during a remote start, and
the engine is still running, turn the key to the RUN
position to drive the vehicle.

Climate Controls
Climate Control System
The climate control system allows manual control of the
heating, cooling, and ventilation in the vehicle.
Fan
9
(Fan):Turn the knob by this symbol, located on the
left side of the climate control panel, clockwise or
counterclockwise to increase or decrease the fan speed.
During the highest fan speed selections, the fan
speed will be temporarily reduced between the transition
to a new mode. The fan will resume the original
speed when the transition to the new mode is complete.
9(Off):Turn the knob to this position to turn the
fan off.
Mode
Turn the middle knob to select the following modes:
H(Vent) Outside Air:This mode directs outside air to
the instrument panel outlets. If driving in city traffic,
and the vehicle is stopped and idling, or the weather is
hot, switch from this mode to the recirculation mode.
To prevent the air inside the vehicle from becoming
stale, be sure to return to the vent mode periodically.
)(Bi-Level):This mode directs half of the air to the
instrument panel outlets, and the remaining air to the oor
outlets. Some air may be directed toward the windshield.
Slightly cooler air is directed to the instrument panel
outlets and warmer air is directed to the oor outlets.
6(Floor):This mode directs most of the air to the oor
outlets with some air directed toward the side window
outlets and a little air directed to the windshield.
In this mode, the system will automatically use outside
air. The air conditioning compressor will be engaged
unless the outside temperature is 40°F (4°C) or below.
Recirculation cannot be selected when in this mode.
The middle knob on the climate control panel can also
be used to select the defog or defrost mode.
3-26

Defogging and Defrosting
Fog on the inside of the vehicle is a result of high
humidity causing moisture to condense on the cool
window glass. This can be minimized if the climate
control system is used properly. There are two modes
to clear frost or fog from the windshield. Use the
defog mode to clear the windows of condensation and
to warm the vehicle’s occupants. Use the defrost
mode to remove frost or condensation from the
windshield quickly. Recirculation cannot be selected
when in these modes.
See “Rear Window Defogger” later in this section for
information on clearing the rear window of fog or ice.
.(Floor/Defog):Use the oor/defog mode to clear the
windows of fog or moisture and warm the passengers.
This mode directs the air equally between the
windshield and the oor outlets, along with some
directed to the side window outlets.
This mode will automatically use outside air. The air
conditioning compressor will be engaged unless
the outside temperature is 40°F (4°C) or below.
1(Defrost):Use the defrost mode to remove fog or
frost from the windshield more quickly. This mode
directs most of the air to the windshield and the side
window outlets, with some air directed to the oor
outlets. This mode has a timer and will shut off after
ve minutes.
This mode will automatically use outside air. The air
conditioning compressor will be engaged unless
the outside temperature is 40°F (4°C) or below.
Temperature
The knob on the right of the climate control panel is the
temperature adjustment that can be used with any of
the climate control modes.
Turn the knob clockwise for warmer settings and
counterclockwise for colder settings.
3-27

Air Conditioning
#
(Air Conditioner):Press this button on the climate
control panel to turn the air conditioning compressor on or
off. An indicator light to the right of the button will come on
to show that the air conditioning is on. This button has no
control over the air conditioning compressor when in the
other modes. The instrument panel brightness control
may have to be adjusted to the highest setting in order to
see the indicator. SeeInstrument Panel Brightness on
page 3-17for additional information.
On hot days during the vehicle’s initial start-up, open
the windows to let hot inside air escape; then close
them. This helps to reduce the time it takes for
the vehicle to cool down. It also helps the system to
operate more efficiently.
For quicker cool down on hot days, do the following:
1. Select the vent/outside air mode.
2. Select the recirculation mode.
3. Select the air conditioner.
4. Select the coolest temperature.
5. Select the highest fan speed.
Using these settings together for long periods of time
may cause the air inside the vehicle to become too dry.
To prevent this from happening, select the vent mode
once the interior of the vehicle is cooled.The air conditioning system removes moisture from the
air, so sometimes there may be a small amount of
water dripping underneath the vehicle while it is idling
or after the engine is turned off. This is normal.
Recirculation
h
(Recirculation):Press this button on the climate
control panel to activate the recirculation mode. With
this selection, inside air is recirculated into the vehicle
along with some outside air. This mode reduces
outside air and odors from entering the vehicle. It may
also help to heat or cool the air inside the vehicle
more quickly.
An indicator light to the right of the button will come
on to show that the recirculation mode is on. The
instrument panel brightness control may have to be
adjusted to the highest setting to see the indicator.
The recirculation mode has a timer. After ve minutes,
the system’s air inlet door will move slightly to allow
for ten percent fresh outside air to maintain interior air
quality. The only way to reset the system to full
recirculation is to restart the ve minute timer by
selecting vent/outside air and recirculation again.
3-28

Air Flow:This control has several settings to control
the direction of airow.
To change the current mode, select one of the following:
AUTO:This mode is automatically set depending on
the temperature in the vehicle and solar sensor
information.
H(Vent):This mode directs air to the instrument
panel outlets.
%(Bi-Level):This mode directs airow to the
instrument panel outlets and to the oor outlets. A small
amount of air is also directed to the windshield and
the side window outlets.
6(Floor):This mode directs most of the air to the
oor outlets with some air directed to the side window
outlets, and a little air directed to the windshield.
#(Air Conditioning):Press this button to turn the
air conditioning compressor on or off. The indicator light
on the button will come on when the air conditioning
is on.
?(Recirculation):Press this button to turn the
recirculation mode on or off. This mode keeps outside
air from coming in the vehicle. It can be used to prevent
outside air and odors from entering your vehicle or to
help cool the air inside your vehicle more quickly.Recirculation is not available in defrost or
oor/defog mode.
Using recirculation for long periods of time may cause
the air inside your vehicle to become too dry. To prevent
this from happening, after the air in your vehicle has
cooled, turn the recirculation mode off.
z(Heated Seats):Press this button to turn the
heated seats on and off. The button on the left controls
the driver’s seat and the button on the right controls
the passenger’s seat. SeeHeated Seats on page 1-4for
additional information.
Sensors
The solar sensor on your vehicle monitors the solar
radiation and the air inside of your vehicle, then uses the
information to maintain the selected temperature by
initiating needed adjustments to the temperature, the fan
speed and the air delivery system. The system may
also supply cooler air to the side of the vehicle facing the
sun. The recirculation mode will also be activated, as
necessary. Do not cover the solar sensor located in the
center of the instrument panel, near the windshield,
or the system will not work properly.
3-31

Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass.
This can be minimized if the climate control system is
used properly. There are two modes to clear fog or
frost from your windshield. Use the oor/defog mode to
clear the windows of fog or moisture and warm the
passengers. Use defrost to remove fog or frost from the
windshield more quickly.
-(Floor/Defog):This mode directs the air between
the windshield, oor outlets and side windows. When
you select this mode, the system turns off recirculation
and runs the air-conditioning compressor unless the
outside temperature is near or below freezing. Pressing
the recirculation button, while in this mode, will have
no effect other than turning on the tell-tale light.
1(Defrost):This mode directs most of the air to the
windshield, with some air directed to the side windows.
IN this mode, the system will automatically turn off
the recirculation and run the air conditioning compressor,
unless the outside temperature is near or below
freezing. Pressing the recirculation button, while in this
mode, will have not effect other than turning on the
tell-tale light.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
The rear window defogger will only work when the
engine is running.
=(Rear Window Defogger):Press this button to
turn the rear window defogger on and off. Be sure
to clear as much snow from the rear window as possible.
The rear window defogger will turn off approximately
20 minutes after the button is pressed. If turned on
again, the defogger will only run for approximately
20 minutes before turning off. The defogger can also be
turned off by pressing the button again or by turning
off the engine.
Do not drive the vehicle until all the windows are clear.
Notice:Don’t use anything sharp on the inside
of the rear window. If you do, you could cut
or damage the warming grid, and the repairs
wouldn’t be covered by your warranty. Do not attach
a temporary vehicle license, tape, a decal or
anything similar to the defogger grid.

until the problem indicated by the warning message
is taken care of. When the problem indicated by
the message is resolved, it can be acknowledged and
the screen can be reset.
Be sure to take any message that appears on the
DIC screen seriously and remember that clearing the
messages that are able to be acknowledged, will
only make the message disappear, not the problem.
A/C OFF FOR ENGINE PROTECTION
This warning message comes on when the engine
coolant becomes hotter than the normal operating
temperature. To avoid added strain on a hot engine,
the air conditioning compressor is automatically turned

Tire Size
The following illustration shows an example of a typical
passenger vehicle tire size.
(A) Passenger (P-Metric) Tire:The United States
version of a metric tire sizing system. The letter P as the
rst character in the tire size means a passenger
vehicle tire engineered to standards set by the U.S. Tire
and Rim Association.
(B) Tire Width:The three-digit number indicates the
tire section width in millimeters from sidewall to sidewall.
(C) Aspect Ratio:A two-digit number that indicates
the tire height-to-width measurements. For example,
if the tire size aspect ratio is 60, as shown in item C of
the illustration, it would mean that the tire’s sidewall
is 60 percent as high as it is wide.(D) Construction Code:A letter code is used to
indicate the type of ply construction in the tire.
The letter R means radial ply construction; the letter D
means diagonal or bias ply construction; and the
letter B means belted-bias ply construction.
(E) Rim Diameter:Diameter of the wheel in inches.
(F) Service Description:These characters represent
the load range and speed rating of the tire. The load
index represents the load carry capacity a tire is certied
to carry. The load index can range from 1 to 279. The
speed rating is the maximum speed a tire is certied
to carry a load. Speed ratings range from A to Z.
Tire Terminology and Denitions
Air Pressure:The amount of air inside the tire pressing
outward on each square inch of the tire. Air pressure
is expressed in pounds per square inch (psi) or
kiloPascal (kPa).
Accessory Weight:This means the combined weight
of optional accessories. Some examples of optional
accessories are, automatic transmission, power steering,
power brakes, power windows, power seats, and air
conditioning.
