The light will remain on until the cause is corrected.
NOTE:
The light may flash momentarily during sharp cornering
maneuvers, which change fluid level conditions. The vehicle
should have service performed, and the brake fluid level
checked.
If brake failure is indicated, immediate repair is necessary.
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 approximately
two seconds. The light should then turn off unless theparking 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 position.
NOTE:
This light shows only that the parking brake is applied. It
does not show the degree of brake application.
— Hood Open Warning Light
This warning light will illuminate when the hood is ajar/
open and not fully closed.
NOTE:
If the vehicle is moving, there will also be a single chime.
— Vehicle Security Warning Light — If Equipped
This light will flash at a fast rate for approximately 15 seconds
when the vehicle security alarm is arming, and then will flash
slowly until the vehicle is disarmed.
WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have failed. It
will take longer to stop the vehicle. You could have a
collision. Have the vehicle checked immediately.

ment or alternate tires and wheels allow the TPMS to
continue to function properly.
— Anti-Lock Brake (ABS) Warning 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 Warning 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 inspected by an authorized dealer.

If Equipped
This warning light will illuminate to indicate a fault in the
Forward Collision Warning System. Contact an authorized
dealer for service.
Refer to “Forward Collision Warning (FCW) With Mitiga -
tion” in “Safety” for further information.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size equipped
on your vehicle. Undesirable system operation or sensor
damage may result when using replacement equipment
that is not of the same size, type, and/or style.
Aftermarket wheels can cause sensor damage. Using
aftermarket tire sealants may cause the Tire Pressure
Monitoring System (TPMS) sensor to become
inoperable. After using an aftermarket tire sealant it is
recommended that you take your vehicle to your
authorized dealer to have your sensor function checked.

SAFETY FEATURES
Anti-Lock Brake System (ABS)
The Anti-Lock Brake System (ABS) provides increased
vehicle stability and brake performance under most braking
conditions. The system automatically prevents wheel lock,
and enhances vehicle control during braking.
The ABS performs a self-check cycle to ensure that the ABS
is working properly each time the vehicle is started and
driven. During this self-check, you may hear a slight clicking
sound as well as some related motor noises.
ABS is activated during braking when the system detects one
or more wheels begin to lock. Road conditions such as ice,
snow, gravel, bumps, railroad tracks, loose debris, or panic
stops may increase the likelihood of ABS activation(s).
You also may experience the following when ABS activates:
• The ABS motor noise (it may continue to run for a shorttime after the stop)
• The clicking sound of solenoid valves • Brake pedal pulsations
• A slight drop of the brake pedal at the end of the stop
These are all normal characteristics of ABS.
WARNING!
• The ABS contains sophisticated electronic equipment that may be susceptible to interference caused by
improperly installed or high output radio transmitting
equipment. This interference can cause possible loss of
anti-lock braking capability. Installation of such equip -
ment should be performed by qualified professionals.
• Pumping of the Anti-Lock Brakes will diminish their effectiveness and may lead to a collision. Pumping
makes the stopping distance longer. Just press firmly
on your brake pedal when you need to slow down or
stop.

SAFETY 199
ABS is designed to function with the Original Equipment
Manufacturer (OEM) tires. Modification may result in
degraded ABS performance.
Anti-Lock Brake Warning Light
The yellow “Anti-Lock Brake Warning Light” will turn on
when the ignition is turned to the ON/RUN mode and may
stay on for as long as four seconds.If the “Anti-Lock Brake Warning Light” remains on or comes
on while driving, it indicates that the anti-lock portion of the
brake system is not functioning and that service is required.
However, the conventional brake system will continue to
operate normally if the “Anti-Lock Brake Warning Light” is
on.
If the “Anti-Lock Brake Warning Light” is on, the brake
system should be serviced as soon as possible to restore the
benefits of anti-lock brakes. If the “Anti-Lock Brake Warning
Light” does not come on when the ignition is turned to the
ON/RUN mode, have the light repaired as soon as possible.
Electronic Brake Control System
Your vehicle is equipped with an advanced Electronic Brake
Control (EBC) system. This system includes Electronic Brake
Force Distribution (EBD), Anti-Lock Brake System (ABS),
Brake Assist System (BAS), Hill Start Assist (HSA), Traction
Control System (TCS), Electronic Stability Control (ESC),
and Electronic Roll Mitigation (ERM). These systems work
together to enhance both vehicle stability and control in
various driving conditions.
Your vehicle may also be equipped with Trailer Sway
Control (TSC) and Hill Descent Control (HDC).
• The ABS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase braking
or steering efficiency beyond that afforded by the
condition of the vehicle brakes and tires or the traction
afforded.
• The ABS cannot prevent collisions, including those resulting from excessive speed in turns, following
another vehicle too closely, or hydroplaning.
• The capabilities of an ABS equipped vehicle must never be exploited in a reckless or dangerous manner
that could jeopardize the user’s safety or the safety of
others.

200 SAFETY
Brake Assist System (BAS)
The Brake Assist System (BAS) is designed to optimize the
vehicle’s braking capability during emergency braking
maneuvers. The system detects an emergency braking situa-
tion by sensing the rate and amount of brake application, and
then applies optimum pressure to the brakes. This can help
reduce braking distances. The BAS complements the
Anti-lock Brake System (ABS). Applying the brakes very
quickly results in the best BAS assistance. To receive the
benefit of the system, you must apply continuous braking
pressure during the stopping sequence, (do not “pump” the
brakes). Do not reduce brake pedal pressure unless braking
is no longer desired. Once the brake pedal is released, the
BAS is deactivated. Brake System Warning Light
The red “Brake System Warning Light” will turn on when
the ignition is turned to the ON/RUN mode and may stay on
for as long as four seconds.
If the “Brake System Warning Light” remains on or comes on
while driving, it indicates that the brake system is not func
-
tioning properly and that immediate service is required. If
the “Brake System Warning Light” does not come on when
the ignition is turned to the ON/RUN mode, have the light
repaired as soon as possible.
Electronic Brake Force Distribution (EBD)
This function manages the distribution of the braking torque
between the front and rear axles by limiting braking pressure
to the rear axle. This is done to prevent overslip of the rear
wheels to avoid vehicle instability, and to prevent the rear
axle from entering ABS before the front axle.
Electronic Roll Mitigation (ERM)
The Electronic Roll Mitigation (ERM) system anticipates the
potential for wheel lift by monitoring the driver’s steering
wheel input and the speed of the vehicle. When ERM deter -
mines that the rate of change of the steering wheel angle and
vehicle’s speed are sufficient to potentially cause wheel lift,
WARNING!
The Brake Assist System (BAS) cannot prevent the
natural laws of physics from acting on the vehicle, nor
can it increase the traction afforded by prevailing road
conditions. BAS cannot prevent collisions, including
those resulting from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning. The capabilities
of a BAS-equipped vehicle must never be exploited in a
reckless or dangerous manner, which could jeopardize
the user's safety or the safety of others.

212 SAFETY
The vehicle’s taillights, where the radar sensors are located,
must remain free of snow, ice, and dirt/road contamination
so that the BSM system can function properly. Do not block
the taillights with foreign objects (bumper stickers, bicycle
racks, etc.).Radar Sensor Locations
If the system detects degraded performance due to contami -
nation or foreign objects, a message will warn you of a
blocked sensor and the warning indicators in side view
mirrors will be on. The warning indicators will remain illu-
minated until blockage clearing conditions are met. First clear the taillights around the sensors of the blockage. After
removing the blockage, the following procedure can be used
to reset the system:
• Cycle the ignition from ON to OFF and then back ON.
If the blockage message is still present after cycling the igni
-
tion and driving in traffic, check again for a blockage.
The BSM system notifies the driver of objects in the detection
zones by illuminating the BSM warning light located in the
outside mirrors, in addition to sounding an audible (chime)
alert and reducing the radio volume. Refer to “Modes Of
Operation” in this section for further information.

For information on how Blind Spot Monitoring functions
when pulling a trailer, refer to “Trailer Merge Assist” in this
section.
Rear Cross Path (RCP)
The Rear Cross Path (RCP) feature is intended to aid the
driver when backing out of parking spaces where their
vision of oncoming vehicles may be blocked. Proceed slowly
and cautiously out of the parking space until the rear end of
the vehicle is exposed. The RCP system will then have a clear
view of the cross traffic, and if an oncoming vehicle is
detected, alert the driver.RCP Detection Zones
RCP monitors the rear detection zones on both sides of the
vehicle, for objects that are moving toward the side of the
vehicle with a minimum speed of approximately 3 mph
(5 km/h), to objects moving a maximum of approximately
20 mph (32 km/h), such as in parking lot situations.
NOTE:
In a parking lot situation, oncoming vehicles can be obscured
by vehicles parked on either side. If the sensors are blocked
by other structures or vehicles, the system will not be able to
alert the driver.
WARNING!
The Blind Spot Monitoring system is only an aid to help
detect objects in the blind spot zones. The BSM system is
not designed to detect pedestrians, bicyclists, or animals.
Even if your vehicle is equipped with the BSM system,
always check your vehicle’s mirrors, glance over your
shoulder, and use your turn signal before changing
lanes. Failure to do so can result in serious injury or
death.
