Tapping RESUME ACCEL once will result in a 1 mph (1.6
km/h) speed increase. Each time the lever is tapped,
speed increases so that tapping the lever three times will
increase speed by 3 mph (4.8 km/h), etc.
To decrease speed while speed control is ON, push down
and hold SET DECEL. Release the lever when the desired
speed is reached, and the new speed will be set.
Tapping the SET DECEL button once will result in a 1
mph (1.6 km/h) speed decrease. Each time the button is
tapped, speed decreases.
NOTE:The Electronic Speed Control System has been
designed to shut down if multiple speed control switch
functions are operated simultaneously in order to ensure
proper operation. If this occurs, the system can be
reactivated by pushing the speed control switch ON/
OFF button and re-setting the desired vehicle SET speed.Manual Transmission
Depressing the clutch pedal will disengage the speed
control. A slight increase in engine RPM before the speed
control disengages is normal.
Vehicles equipped with manual transmissions may need
to be shifted into a lower gear to climb hills without
speed loss.
WARNING!
Speed Control can be dangerous where the system
can’t maintain a constant speed. Your vehicle could
go too fast for the conditions, and you could lose
control. An accident could be the result. Do not use
Speed Control in heavy traffic or on roads that are
winding, icy, snow-covered, or slippery.

To Accelerate For Passing
Depress the accelerator as you would normally. When the
pedal is released, the vehicle will return to the set speed.
Using Speed Control On Hills
NOTE:The speed control system maintains speed up
and down hills. A slight speed change on moderate hills
is normal.
On steep hills, a greater speed loss or gain and/or more
frequent downshifts (auto transmission only) may occur
so it may be preferable to drive without speed control.
ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced electronic
brake control system that includes ABS (Anti-Lock Brake
System), TCS (Traction Control System), BAS (Brake
Assist System), ERM (Electronic Roll Mitigation), and ESP (Electronic Stability Program). All five of these
systems work together to enhance vehicle stability and
control in various driving conditions.
ABS (Anti-Lock Brake System)
This system aids the driver in maintaining vehicle control
under adverse braking conditions. The system controls
hydraulic brake pressure to prevent wheel lock-up and
help avoid skidding on slippery surfaces during braking.
Refer to “Anti-Lock Brake System” in Section 5 of this
manual for more information about ABS.

21. Odometer/Trip Odometer Reset Button
Press this button to change the display from odometer to
either of two trip odometer settings. Trip A or Trip B will
appear when in the trip odometer mode. Press and hold
the button for two seconds to reset the trip odometer to 0
miles or kilometers. The odometer must be in trip mode
to reset.
22. Transmission Range Indicator
This display indicator shows the automatic transmission
gear selection.
23. Tire Pressure Monitoring Telltale LightEach tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle
has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those
tires.)
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system (TPMS)
that illuminates a low tire pressure telltale when one or
more of your tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illuminates, you
should stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect the vehicle’s
handling and stopping ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver ’s responsibility to
maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.

2. Fully depress the accelerator pedal slowly three
times within 10 seconds.
3. Turn the ignition switch to the OFF/LOCK position.
NOTE: If the indicator message illuminates when you
start the vehicle, the oil change indicator system did not
reset. If necessary repeat this procedure.
25. Malfunction Indicator Light This light is a part of an Onboard Diagnostic
System called OBD II that monitors engine and
automatic transmission control systems. The light
will illuminate when the ignition is in the ON position
before engine start. If the bulb does not come on when
turning the key from OFF to ON, have the condition
checked promptly.
Certain conditions such as a loose or missing gas cap,
poor quality fuel, etc. may illuminate the light after
engine start. The vehicle should be serviced if the light stays on through several typical driving styles. In most
situations, the vehicle will drive normally and will not
require towing.
When the engine is running, the Malfunction Indicator
Light may flash to alert serious conditions that could lead
to immediate loss of power or severe catalytic converter
damage. The vehicle should be serviced as soon as
possible if this occurs.
26. Electronic Stability Program (ESP) Indicator
Light/Traction Control System (TCS) Indicator Light
This indicator light starts to flash as soon as the
tires lose traction and the ESP system becomes
active. The ESP/TCS Indicator Light also
flashes when TCS is active. If the ESP/TCS
Indicator Light begins to flash during acceleration, ease
up on the accelerator and apply as little throttle as
possible. Be sure to adapt your speed and driving to the
prevailing road conditions. The ESP/TCS Indicator Light

NOTE:Magnetic materials should be kept away from
the top of the instrument panel above the radio. This is
where the compass sensor is located.
Automatic Compass Calibration
The self-calibrating feature of the compass eliminates the
need to calibrate the compass for normal conditions.
During a short initial period, the compass may appear
erratic and the CAL symbol will appear (blinking) on the
display. After the vehicle has completed at least one
complete circle under 5 mph (8 km/h) in an area free
from large metal objects, calibration will be complete
when the CAL symbol is extinguished.
After initial calibration, the compass will continue to
automatically update this calibration whenever the ve-
hicle is in motion.
Manual Compass Calibration
NOTE: Before attempting a manual compass calibra-
tion, the engine must be running and the transmission
in the PARK position (if equipped).
If the compass seems in error or erratic, you may wish to
manually recalibrate the compass. To manually calibrate
the compass, you must first enter the variance mode.
Press and hold the left button (located on the instrument
cluster) for approximately 10 seconds to enter the vari-
ance mode, and release the button when the VAR (Com-
pass Variance) symbol appears. The current variance
value will also be displayed. Once in the variance mode,
it is necessary to release the button, and then press and
hold it again (approximately 10 seconds) until CAL is
displayed (solid, not blinking). Manual compass calibra-
tion has been initiated. Drive the vehicle slowly in one or
more circles under 5 mph (8 km/h) in an area free from
large metal objects until the CAL symbol is extinguished.

Outside Temperature
If the outside temperature is more than 131°F (55°C), the
display will show 131°F (55°C). When the outside tem-
perature is less than40°F (40°C), the display will
show 40°F (40°C).
RADIO GENERAL INFORMATION
Radio Broadcast Signals
The radio will provide excellent reception under most
operating conditions. Like any system, however, automo-
tive radios have performance limitations, due to mobile
operation and natural phenomena, which might lead you
to believe your sound system is malfunctioning. To help
you understand and save you concern about these “ap-
parent” malfunctions, you must understand a point or
two about the transmission and reception of radio sig-
nals.
220 UNDERSTANDING YOUR INSTRUMENT PANEL

Two Types of Signals
There are two basic types of radio signals: AM or
Amplitude Modulation, in which the transmitted sound
causes the amplitude, or height, of the radio waves to
vary; and FM or Frequency Modulation, in which the
frequency of the wave is varied to carry the sound.
Electrical Disturbances
Radio waves may pick up electrical disturbances during
transmission. They mainly affect the wave amplitude,
and thus remain a part of the AM reception. They
interfere very little with the frequency variations that
carry the FM signal.
AM Reception
AM sound is based on wave amplitude, so AM reception
can be disrupted by such things as lightning, power lines
and neon signs.
FM Reception
Because FM transmission is based on frequency varia-
tions, interference that consists of amplitude variations
can be filtered out, leaving the reception relatively clear,
which is the major feature of FM radio.
NOTE:The radio, steering wheel radio controls (if
equipped), and six-disc CD/DVD changer (if equipped)
will remain active for up to 10 minutes after the ignition
switch has been turned OFF. Opening a vehicle front
door will cancel this feature.
