vehicle and run the engine at idle or slightly
faster, with the transmission in PARK or
NEUTRAL, until the light turns off. Once the
light turns off, you may continue to drive
normally.
WARNING!
If you continue operating the vehicle when
the Transmission Temperature Warning
Light is illuminated you could cause the
fluid to boil over, come in contact with hot
engine or exhaust components and cause
a fire.
CAUTION!
Continuous driving with the Transmission
Temperature Warning Light illuminated
will eventually cause severe transmission
damage or transmission failure.
— Vehicle Security Warning Light — If
Equipped
This light will flash at a fast rate for approxi-
mately 15 seconds when the vehicle security
alarm is arming, and then will flash slowly
until the vehicle is disarmed.
Yellow Warning Lights

Light
This warning light monitors the Anti-Lock
Brake System (ABS). The light will turn on
when the ignition is placed in the ON/RUN or
ACC/ON/RUN position and may stay on for as
long as four seconds.
If the ABS light remains on or turns on while
driving, then the Anti-Lock portion of the
brake system is not functioning and service is
required as soon as possible. However, the
conventional brake system will continue to
operate normally, assuming the Brake Warn-
ing Light is not also on.

tions are operated at the same time. If this
occurs, the Speed Control System can be
reactivated by pushing the Speed Control
on/off button and resetting the desired ve-
hicle set speed.
WARNING!
Speed Control can be dangerous where the
system cannot maintain a constant speed.
Your vehicle could go too fast for the con-
ditions, and you could lose control and
have an accident. Do not use Speed Con-
trol in heavy traffic or on roads that are
winding, icy, snow-covered or slippery.
To Activate
Push the on/off button to activate the Speed
Control. “CRUISE CONTROL READY” will
appear in the instrument cluster display to
indicate the Speed Control is on. To turn the
system off, push the on/off button a second
time. “CRUISE CONTROL OFF” will appear
in the instrument cluster display to indicate
the Speed Control is off. The system should
be turned off when not in use.
WARNING!
Leaving the Speed Control system on when
not in use is dangerous. You could acci-
dentally set the system or cause it to go
faster than you want. You could lose con-
trol and have an accident. Always leave the
system OFF when you are not using it.
To Set A Desired Speed
Turn the Speed Control on. When the vehicle
has reached the desired speed, push the SET
(+) or SET (-) button and release. Release the
accelerator and the vehicle will operate at the
selected speed. Once a speed has been set, a
message “CRUISE CONTROL SET TO MPH
(km/h)” will appear indicating what speed
was set. A cruise indicator lamp, along with
set speed will also appear and stay on in the
instrument cluster when the speed is set.

To Deactivate
A soft tap on the brake pedal, pushing the
CANC button, or normal brake pressure while
slowing the vehicle will deactivate the Speed
Control without erasing the set speed from
memory.
Pushing the on/off button or turning the igni-
tion switch OFF erases the set speed from
memory.
ADAPTIVE CRUISE
CONTROL (ACC) — IF
EQUIPPEDIf your vehicle is equipped with Adaptive
Cruise Control, the controls operate exactly
the same as Speed Control with only a couple
of differences. With this option, you can set a
specified distance you would like to maintain
between you and the vehicle in front of you.
If the ACC sensor detects a vehicle ahead,
ACC will apply limited braking or acceleration
automatically to maintain a preset following
distance, while matching the speed of the
vehicle ahead.
If the sensor does not detect a vehicle ahead
of you, ACC will maintain a fixed set speed.
To Activate/Deactivate
Push and release the Adaptive Cruise Control
(ACC) on/off button. The ACC menu in the
instrument cluster displays “ACC Ready.”
To turn the system off, push and release the
Adaptive Cruise Control (ACC) on/off button

WARNING!
Leaving the Adaptive Cruise Control (ACC)
system on when not in use is dangerous.
You could accidentally set the system or
cause it to go faster than you want. You
could lose control and have a collision.
Always leave the system off when you are
not using it.
To Set A Desired ACC Speed
When the vehicle reaches the speed desired,
push the SET(+)button or the SET(-)button
and release. The instrument cluster display
will display the set speed.
If the system is set when the vehicle speed is
below 19 mph (30 km/h), the set speed shall
be defaulted to 19 mph (30 km/h). If the
system is set when the vehicle speed is above
19 mph (30 km/h), the set speed shall be the
current speed of the vehicle.
NOTE:
ACC cannot be set if there is a stationary
vehicle in front of your vehicle in close
proximity.Remove your foot from the accelerator pedal.
If you do not, the vehicle may continue to
accelerate beyond the set speed. If this oc-
curs:
• The message “DRIVER OVERRIDE” will
display in the instrument cluster display.
• The system will not be controlling the dis-
tance between your vehicle and the vehicle
ahead. The vehicle speed will only be de-
termined by the position of the accelerator
pedal.
To Resume
If there is a set speed in memory push the
RES (resume) button and then remove your
foot from the accelerator pedal. The instru-
ment cluster display will display the last set
speed.
NOTE:
• If your vehicle stays at standstill for longer
than two seconds, then the system will
cancel and the brake force will be ramped-
out. The driver will have to apply the brakes
to keep the vehicle at a standstill.• ACC cannot be resumed if there is a station-
ary vehicle in-front of your vehicle in close
proximity.
WARNING!
The Resume function should only be used
if traffic and road conditions permit. Re-
suming a set speed that is too high or too
low for prevailing traffic and road condi-
tions could cause the vehicle to accelerate
or decelerate too sharply for safe opera-
tion. Failure to follow these warnings can
result in a collision and death or serious
personal injury.
To Vary The Speed Setting
To Increase Speed
While ACC is set, you can increase the set
speed by pushing the SET(+)button.
The driver's preferred units can be selected
through the instrument panel settings. Refer
to “Getting To Know Your Instrument Panel”
