Matching Transmitter(s) to Your Vehicle
Each RKE transmitter is coded to prevent another
transmitter from unlocking your vehicle. If a transmitter
is lost or stolen, a replacement can be purchased
through your dealer/retailer. All transmitters need to be
re-coded to match the new transmitter. The lost
transmitter will no longer work after the new transmitters
are re-coded. The vehicle can have a maximum of
eight transmitters matched to it. See “Relearn Remote
Key” underDIC Operation and Displays (Using DIC
Buttons) on page 3-49orDIC Operation and Displays
(Using Trip Odometer Reset Stem) on page 3-54
for instructions on how to match RKE transmitters to
your vehicle.
Battery Replacement
Replace the battery if the REPLACE BATTERY IN
REMOTE KEY message displays in the DIC. See
“REPLACE BATTERY IN REMOTE KEY” underDIC
Warnings and Messages on page 3-56for additional
information.
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.To replace the battery in the RKE transmitter:
1. Separate the halves of the transmitter with a at,
thin object inserted into the notch on the side.
2. Remove the old battery. Do not use a metal object.
3. Insert the new battery, positive side facing down.
Replace with a CR2032 or equivalent battery.
4. Put the transmitter back together tightly.

Driver Shift Control (DSC)
Your vehicle has a Driver
Shift Control (DSC).
The DSC controls the
vehicle’s transmission
and vehicle speed while
driving down hill or towing
a trailer by allowing you
to select a desired range
of gears.
To use this feature:
1. Move the shift lever to the MANUAL MODE (M).
This will force a downshift from the current gear,
for gears 3 through 6.
2. Press the (+) plus or (−) minus button on the left
side of the steering wheel, to select the desired
range of gears for your current driving conditions.When in the MANUAL MODE (M) a number will display
next to the M, indicating the maximum available
gear. The DIC display will show the message MANUAL
SHIFT on the rst line and the maximum available
gear will be displayed on the second line. SeeDriver
Information Center (DIC) on page 3-49andDIC
Operation and Displays (Using DIC Buttons) on
page 3-49orDIC Operation and Displays (Using Trip
Odometer Reset Stem) on page 3-54for more
information. The number displayed in the DIC is the
highest gear available. The transmission will be limited
to the gear selected and lower gears. Shifting will
occur normally while driving, however the cluster will
continue to display the maximum available gear.
Higher gears will not be available unless the selection
is changed to include higher gears using the (+) plus
button.
Grade Braking is not available when the Driver Shift
Control is active. SeeTow/Haul Mode on page 2-36and
Towing a Trailer on page 4-55for more information.
While using the DSC, cruise control and the tow/haul
mode can be used.

Windshield Washer
{CAUTION:
In freezing weather, do not use your washer
until the windshield is warmed. Otherwise the
washer uid can form ice on the windshield,
blocking your vision.

to help clear ice, snow, tree sap, or bugs from your
windshield.To activate Automatic mode for de-icing, press the
heated washer button located to the left of the
steering wheel below the instrument panel brightness
control knob. Pushing the heated washer uid button
activates the heated windshield washer uid system.
This activation will initiate four heated wash/wipe cycles.
The rst heated wash/wipe cycle may take up to
40 seconds to occur, depending on outside temperature.
After the rst wash/wipe cycle, it may take up to
20 seconds for each of the remaining cycles. The heated
windshield washer uid system may be turned off at
any time by pushing the button again prior to the
completion of 4 wash/wipe cycles.
When the heated windshield washer uid system is
activated under certain outside temperature conditions,
steam may ow out of the washer nozzles for a short
period of time before washer uid is sprayed. This is
a normal condition. A message will be displayed on
the Driver Information Center (DIC) when the washer
uid is low. SeeDIC Warnings and Messages on
page 3-56.

more, press the +RES button on the steering wheel.
The vehicle will return to the previously set speed
and stay there.
Increasing Speed While Using
Cruise Control
To increase the cruise speed while using cruise control:
Press and hold the +RES button on the steering
wheel until the desired speed is reached, then
release it.
To increase vehicle speed in small increments,
press the +RES button. Each time this is done,
the vehicle will go about 1 mph (1.6 km/h) faster.
Reducing Speed While Using
Cruise Control
To reduce the vehicle’s speed while using
cruise control:
Press and hold the SET– button on the
steering wheel until the desired lower

Speedometer and Odometer
Your speedometer lets you see your speed in both
miles per hour (mph) and kilometers per hour (km/h).
Your vehicle’s odometer works together with the
driver information center. You can set a Trip odometer.
See “Trip Odometer” underDIC Operation and
Displays (Using DIC Buttons) on page 3-49or
DIC Operation and Displays (Using Trip Odometer
Reset Stem) on page 3-54for more information.
The odometer mileage can be checked without the
vehicle running. Simply press the trip stem on the
instrument panel cluster.
If your vehicle ever needs a new odometer installed,
the new one will be set to the correct mileage total
of the old odometer.
Trip Odometer
The trip odometer can tell you how far your vehicle has
been driven since you last set the trip odometer to zero.
Press the trip stem to toggle between the trip odometer
and the regular odometer. Holding the trip stem for
approximately one second while the trip odometer is
displayed will reset it.
To display the odometer reading with the ignition off,
press the trip stem.
Tachometer
Your tachometer displays the engine speed in
revolutions per minute (rpm).
Safety Belt Reminders
Safety Belt Reminder Light
When the engine is started, a chime will come on for
several seconds to remind people to fasten their safety
belts, unless the driver’s safety belt is already buckled.
The safety belt light will
also come on and stay
on for several seconds,
then it will ash for
several more.
This chime and light is repeated if the driver remains
unbuckled and the vehicle is in motion. If the driver’s
belt is already buckled, neither the chime nor the
light will come on.

{CAUTION:
Your brake system may not be working properly
if the brake system warning light is on. Driving
with the brake system warning light on can lead
to an accident. If the light is still on after you
have pulled off the road and stopped carefully,
have the vehicle towed for service.
If the light comes on while you are driving, pull off
the road and stop carefully. You may notice that the
pedal is harder to push or may go closer to the oor.
It may take longer to stop. If the light is still on, have
the vehicle towed for service. SeeTowing Your
Vehicle on page 4-51.
Antilock Brake System
Warning Light
For vehicles with
the Antilock Brake
System (ABS), this
light will come on
briey when you
start the engine.
That is normal. If the light does not come on then,
have it xed so it will be ready to warn you if there
is a problem.
If the ABS light stays on, turn the ignition off, if the light
comes on when you are driving, stop as soon as it is
safely possible and turn the ignition off. Then start the
engine again to reset the system. If the ABS light still
stays on, or comes on again while you are driving,
your vehicle needs service. If the regular brake system
warning light is not on, you still have brakes, but you do
not have antilock brakes. If the regular brake system
warning light is also on, you do not have antilock
brakes and there is a problem with your regular brakes.
SeeBrake System Warning Light on page 3-38
For vehicles with a Driver Information Center (DIC),
seeDIC Warnings and Messages on page 3-56for
all brake related DIC messages.
