Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about four years.
You can tell the battery is weak if the transmitter won’t
work at the normal range in any location. If you have
to get close to your vehicle before the transmitter works,
it’s probably time to change the battery.
Notice:When replacing the battery, use care not to
touch any of the circuitry. Static from your body
transferred to these surfaces may damage the
transmitter.
1. Use a at thin object to pry open the transmitter.
2. Once the transmitter is separated, use a pencil
or similar object to remove the old battery.
Do not use a metal object.3. Insert the new battery as the instructions under the
cover indicate.
4. Snap the transmitter back together tightly to be sure
no moisture can enter.
5. Press any button on the remote keyless entry
transmitter to resynchronize the transmitter.
6. Check the operation of the transmitter.

Starting the Engine
Automatic Transmission
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine will not start in any other position — that is
a safety feature. To restart when you are already
moving, use NEUTRAL (N) only.
Notice:Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.
Manual Transmission
The shift lever should be in NEUTRAL and the parking
brake engaged. Hold the clutch pedal to the oor and
start the engine. Your vehicle will not start if the clutch
pedal is not all the way down — that is a safety feature.
1. With your foot off the accelerator pedal, turn your
ignition key to START. Then, let go of the key; the
engine will start automatically. The idle speed
will go down as your engine gets warm. Do not race
the engine immediately after starting it. Operate
the engine and transmission gently until the
oil warms up and lubricates all moving parts.Your vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the
engine and protects the electrical system. If the
ignition key is turned to the START position,
and then released when the engine begins cranking,
the engine will continue cranking until the vehicle
starts or until it exceeds the maximum cranking time
allowed, approximately 15 seconds to prevent
cranking motor damage. To prevent starter-motor
gear damage, this system also prevents cranking if
the engine is already running. The engine cranking
can be stopped by turning the ignition switch to
the ACCESSORY or OFF position.
2. If your engine will not start, or starts but then stops,
it could be ooded with too much gasoline. Try
pushing your accelerator pedal all the way to the
oor and holding it there as you turn the key
to START. If the vehicle starts brie y but then stops
again, do the same thing.
Notice:Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer. If you do not, your engine
might not perform properly. Any resulting damage
would not be covered by your vehicle’s warranty.

Driver Shift Control (DSC)
Notice:If you drive your vehicle at high RPMs
without upshifting while using Driver Shift Control
(DSC), you could damage your vehicle. Always
upshift when necessary while using DSC.
Your automatic transmission has a Driver Shift Control
(DSC) feature that allows you to change gears similar to a
manual transmission. To use the DSC feature:
1. Slide the shift lever over from AUTOMATIC
OVERDRIVE (D) to the right into the DSC area.
The sport mode light in the
instrument panel cluster
will come on.
If you do not move the shift lever forward or
rearward, the vehicle will be in sport mode. When
you are in the sport mode the vehicle will still
shift automatically. While driving in sport mode, the
transmission may remain in a gear longer than it
would in the normal driving mode based on braking,
throttle input, and vehicle lateral acceleration.
2. To enter the DSC mode, press the shift lever
forward to upshift or rearward to downshift.The odometer on the instrument panel cluster will
change from the mileage to a number indicating the
requested gear range when moving the shift lever
forward or rearward. SeeSpeedometer and Odometer
on page 3-33for more information on the odometer.
While using the DSC feature, the vehicle will have rmer
shifting and increased performance. You can use this
for sport driving or when climbing or descending hills, to
stay in gear longer, or to down shift for more power
or engine braking.
The transmission will only allow you to shift into gears
appropriate for the vehicle speed and engine
Revolutions Per Minute (RPM). The transmission will
not automatically shift to the next higher gear if the
engine RPM is too high.
If shifting is prevented for any reason, the currently
selected gear will ash multiple times, indicating that the
transmission has not shifted gears.
While in the DSC mode, the transmission will
automatically downshift when the vehicle comes to a stop
and while quickly applying the accelerator to increase
speed. This will allow for more power during take-off.
When accelerating your vehicle from a stop in snowy
and icy conditions, you may want to shift into second
gear. A higher gear ratio allows you to gain more traction
on slippery surfaces.

Turn Signal On Chime
If the turn signal is left on for about 1 mile (1.6 km), a
warning chime will sound and the Turn Signal On
message will appear on the Driver Information
Center (DIC) display. See “Turn Signal On” under
DIC Warnings and Messages on page 3-61for more
information.
Headlamp High/Low-Beam Changer
Push forward on the turn signal/multifunction lever
to change the headlamps from low to high beam. Pull
the lever back and then release it to change from high to
low beam.
If you turn the vehicle off with the high beams on,
the high beams will be on the next time you start
your vehicle.
This light on the
instrument panel cluster
will be on, indicating
high-beam usage.
Flash-to-Pass
This feature allows you to use the high-beam headlamps
to signal the driver in front of you that you want to pass.
Pull and hold the turn signal/multifunction lever toward
you to use this feature. When you do this, the following
will occur:
If the headlamps are off, in low-beam or in Daytime
Running Lamps (DRL) mode, the high-beam
headlamps will turn on. They will stay on as long as
you hold the lever there. Release the lever to
turn them off.
If the headlamps are in high-beam mode, they will
switch to low beam. To return to high-beam, push
the lever away from you.

Automatic Operation
AUTO (Automatic):When this button is pressed and
the temperature is set, the system will automatically
control the inside temperature, the air delivery mode,
the air conditioning compressor, and the fan speed.
AUTO will appear on the display.
1. Press the AUTO button.
2. Adjust the temperature to a comfortable setting
between 70°F (21°C) and 80°F (27°C).
Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool
any faster. If you set the system at the warmest
temperature setting, the system will remain in
manual mode at that temperature and it will not go
into automatic mode.
In cold weather, the system will start at reduced fan
speeds to avoid blowing cold air into your vehicle
until warmer air is available. The system will
start out blowing air at the oor but may change
modes automatically as the vehicle warms up
to maintain the chosen temperature setting. The
length of time needed for warm up will depend on
the outside temperature and the length of time
that has elapsed since your vehicle was last driven.
3. Wait for the system to regulate. This may take from
10 to 30 minutes. Then adjust the temperature, if
necessary.You can switch from English to metric units through the
Driver Information Center (DIC). If you have the Base
audio system, seeDIC Main Menu on page 3-57.Ifyou
have the Navigation system, see “Setup Menu” in the
Index of the Navigation System Owner Manual.
The air-conditioning system removes moisture from the
air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling
or after turning off the engine. This is normal.
Do not cover the solar sensor located in the center of
the instrument panel, near the windshield. For more
information on the solar sensor, see “Sensors” later in
this section.
Manual Operation
yNz(Mode):Pressing the mode switch and
changing the mode cancels automatic operation and
places the system in manual mode. Press AUTO
to return to automatic operation.
The outboard air outlets will always receive air ow
regardless of the mode selected. SeeOutlet Adjustment
on page 3-28to change this air ow from the outboard
outlets.
3-24
To change the current mode, select one of the following:
Y(Vent):This mode directs air to the instrument
panel outlets.
\(Bi-Level):This mode directs approximately half of
the air to the instrument panel outlets, and then
directs most of the remaining air to the oor outlets. In
automatic operation, cooler air is directed to the
upper outlets and warmer air to the oor outlets.
[(Floor):This mode directs most of the air to the
oor outlets with some air directed to the outboard
outlets (for the side windows), and a little air directed to
the windshield.
The mode switch can also be used to select the defog
mode. Information on defogging and defrosting can
be found later in this section.
yAz(Fan):Press this switch to increase or
decrease the fan speed. Pressing this switch cancels
automatic operation and places the system in manual
mode. Press AUTO to return to automatic operation.
If the air ow seems low when the fan speed is at
the highest setting, the passenger compartment air lter
may need to be replaced. For more information, see
Passenger Compartment Air Filter on page 3-29
andScheduled Maintenance on page 6-4.
h(Recirculation):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 heat or cool the air inside your vehicle more
quickly. Press this button to turn the recirculation mode
on or off. The air-conditioning compressor also comes
on. After manually selecting recirculation, the auto button
must be pressed to enable the system to select the
optimum air delivery setting for the vehicle.
Recirculation is not available in the defog or defrost
mode and will automatically turn off after 10 minutes
when defog is selected.
Using recirculation for long periods of time may cause
the air inside your vehicle to become too dry or stuffy.
To prevent this from happening, after the air in your
vehicle has cooled, turn the recirculation mode off
or press the auto button.
QPWRR(Power/Driver’s Temperature):Press
the PWR button located on the driver’s side of
the climate control panel to turn the entire climate
control system on or off. Press the up or down arrow on
the switch to increase or decrease the temperature
inside your vehicle.
