To Deactivate
A soft tap on the brake pedal, pushing the CANCEL
button, or normal brake pressure while slowing the
vehicle will deactivate Electronic Speed Control without
erasing the set speed memory. Pressing the ON/OFF
button or turning the ignition switch OFF erases the set
speed memory.
To 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). To Vary The Speed Setting
When the Electronic Speed Control is set, you can in-
crease speed by pushing the RES (+) button. If the button
is continually pressed, the set speed will continue to
increase until the button is released, then the new set
speed will be established.
Pressing the RES (+) button once will result i na1mph
(1.6 km/h) increase in set speed. Each subsequent tap of
the button results in an increase of 1 mph (1.6 km/h).
To decrease speed while the Electronic Speed Control is
set, push the SET (-) button. If the button is continually
held in the SET (-) position, the set speed will continue to
decrease until the button is released. Release the button
when the desired speed is reached, and the new set speed
will be established.180 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

11. Brake Warning Light
This light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on it may
indicate that the parking brake is applied, that
the brake fluid level is low, or that there is a problem with
the anti-lock brake system reservoir.
If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the
Brake Booster has been detected by the Anti-Lock Brake
System (ABS) / Electronic Stability Control (ESC) system.
In this case, the light will remain on until the condition
has been corrected. If the problem is related to the brake
booster, the ABS pump will run when applying the brake
and a brake pedal pulsation may be felt during each stop. The dual brake system provides a reserve braking capac-
ity in the event of a failure to a portion of the hydraulic
system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is corrected.
NOTE: The light may flash momentarily during sharp
cornering maneuvers, which change fluid level condi-
tions. The vehicle should have service performed, and
the brake fluid level checked.
If brake failure is indicated, immediate repair is necessary.
WARNING!Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have failed. (Continued)302 UNDERSTANDING YOUR INSTRUMENT PANEL

WARNING! (Continued)It will take longer to stop the vehicle. You could have
a collision. Have the vehicle checked immediately.
Vehicles equipped with the Anti-Lock Brake System
(ABS), are also equipped with Electronic Brake Force
Distribution (EBD). In the event of an EBD failure, the
Brake Warning Light will turn on along with the ABS
Light. Immediate repair to the ABS system is required.
Operation of the Brake Warning Light can be checked by
turning the ignition switch from the OFF position to the
ON/RUN position. The light should illuminate for ap-
proximately two seconds. The light should then turn off
unless the parking brake is applied or a brake fault is
detected. If the light does not illuminate, have the light
inspected by an authorized dealer. The light also will turn on when the parking brake is
applied with the ignition switch in the ON/RUN posi-
tion.
NOTE: This light shows only that the parking brake is
applied. It does not show the degree of brake application.
12. Anti-Lock Brake (ABS) Light
After the ignition is turned on, the Anti-Lock
Brake System (ABS) light illuminates to indicate
function check at vehicle start-up. If the light remains on
after start-up or comes on and stays on at road speeds, it
may indicate that the ABS has detected a malfunction or
has become inoperative. The system reverts to standard
non-anti-lock brakes.
If both the Brake Warning Light and the ABS Warning Light
are on, see an authorized dealer immediately. Refer to
“Anti-Lock Brake System” in “Starting And Operating”.
