Yellow Warning Lights
— Service Adaptive Cruise Control
Warning Light
This light will turn on when the ACC system is
not operating and needs service. For further
information, refer to “Adaptive Cruise Control
(ACC)” in “Starting And Operating.”
— Anti-Lock Brake (ABS) Warning
Light
This light monitors the Anti-Lock Brake Sys-
tem (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.If the ABS light does not turn on when the
ignition is placed in the ON/RUN or ACC/ON/
RUN position, have the brake system in-
spected by an authorized dealer.
— Electronic Stability Control (ESC) Off
Warning Light — If Equipped
This light indicates the Electronic Stability
Control (ESC) is off.
Each time the ignition is turned to ON/RUN
or ACC/ON/RUN, the ESC system will be on,
even if it was turned off previously.
The ESC OFF indicator will be lit any time the
Traction Mode is set to Sport, Track or Full
OFF in Drive Modes.
— Electronic Stability Control (ESC)
Active Warning Light — If Equipped
This light will indicate when the Electronic
Stability Control system is Active. The “ESC
Indicator Light” in the instrument cluster will
come on when the ignition is placed in the
ON/RUN or ACC/ON/RUN position, and when
ESC is activated. It should go out with the
engine running. If the “ESC Indicator Light”
comes on continuously with the engine run-ning, a malfunction has been detected in the
ESC system. If this light remains on after
several ignition cycles, and the vehicle has
been driven several miles (kilometers) at
speeds greater than 30 mph (48 km/h), see
your authorized dealer as soon as possible to
have the problem diagnosed and corrected.
• The “ESC Off Indicator Light” and the
“ESC Indicator Light” come on momen-
tarily each time the ignition is placed in the
ON/RUN or ACC/ON/RUN position.
• The ESC system will make buzzing or click-
ing sounds when it is active. This is normal;
the sounds will stop when ESC becomes
inactive.
• This light will come on when the vehicle is
in an ESC event.— Service LaneSense Warning Light

NOTE:
In order to ensure proper operation, the
Speed Control System has been designed to
shut down if multiple Speed Control func-
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.
Activation
Push the on/off button to activate the speed
control. CRUISE CONTROL READY will ap-
pear on 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 on
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.
Setting 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 display when the speed is
set.
Varying The Speed
Once the Speed Control has been activated,
the speed can be increased or decreased.
To Increase Speed
When the Speed Control is set, you can in-
crease speed by pushing the SET(+)button.
The driver's preferred units can be selected
through the instrument panel settings if
equipped. Refer to “Getting To Know Your
Instrument Panel” in the Owner’s Manual for
more information. The speed increment
shown is dependant on the chosen speed unit
of U.S. (mph) or Metric (km/h):
U.S. Speed (mph)
• Pushing the SET(+)button once will result
in a 1 mph increase in set speed. Each
subsequent tap of the button results in an
increase of 1 mph.
• If the button is continually pushed, the set
speed will continue to increase until the
button is released, then the new set speed
will be established.
STARTING AND OPERATING
164

Metric Speed (km/h)
• Pushing the SET(+)button once will result
in a 1 km/h increase in set speed. Each
subsequent tap of the button results in an
increase of 1 km/h.
• If the button is continually pushed, the set
speed will continue to increase until the
button is released, then the new set speed
will be established.
To Decrease Speed
When the Speed Control is set, you can de-
crease speed by pushing the SET(-)button.
The driver's preferred units can be selected
through the instrument panel settings if
equipped. Refer to “Getting To Know Your
Instrument Panel” in the Owner’s Manual for
more information. The speed increment
shown is dependant on the chosen speed unit
of U.S. (mph) or Metric (km/h):
U.S. Speed (mph)
• Pushing the SET(-)button once will result
in a 1 mph decrease in set speed. Each
subsequent tap of the button results in a
decrease of 1 mph.• If the button is continually pushed, the set
speed will continue to decrease until the
button is released, then the new set speed
will be established.
Metric Speed (km/h)
• Pushing the SET(-)button once will result
in a 1 km/h decrease in set speed. Each
subsequent tap of the button results in a
decrease of 1 km/h.
• If the button is continually pushed, the set
speed will continue to decrease until the
button is released, then the new set speed
will be established.
Resume Speed
To resume a previously set speed, push the
RES button and release. Resume can be used
at any speed above 20 mph (32 km/h).
Accelerating For Passing
Press the accelerator as you would normally.
When the pedal is released, the vehicle will
return to the set speed.
Deactivation
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 your vehicle is equipped with Adaptive
Cruise Control, the controls operate exactly
the same as the 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.
165

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.
Activation
Push and release the Adaptive Cruise Control
(ACC) on/off button.
“ACC READY” will appear in the instrument
cluster display to indicate the ACC is on.
Setting A Desired Speed
When the vehicle reaches the speed desired,
push the SET(+)button or the SET(-)button
and release. The instrument cluster display
will show 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 prox-
imity.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
appear 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.
Varying The Speed
Once the ACC has been activated, the speed
can be increased or decreased.
NOTE:
• When you override and push the SET(+)
button or SET(-)buttons, the new set
speed will be the current speed of the
vehicle.
• When you use the SET(-)button to decel-
erate, if the engine’s braking power does
not slow the vehicle sufficiently to reach
the set speed, the brake system will auto-
matically slow the vehicle.Adaptive Cruise Switches
