SAFETY
SAFETY FEATURES
ANTI-LOCK BRAKE SYSTEM (ABS)
The 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 are
beginning 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 normal
characteristics when ABS activates:
The ABS motor noise or clicking sounds (you
may continue to hear for a short time after
the stop)
Brake pedal pulsations
A slight drop of the brake pedal at the end of
the stop

ABS is designed to function with the Original
Equipment Manufacturer (OEM) tires. Modification
may result in degraded ABS performance.

WARNING!
The ABS contains sophisticated electronic
equipment that may be susceptible to inter -
ference caused by improperly installed or
high output radio transmitting equipment.
This interference can cause possible loss of
anti-lock braking capability. Installation of
such equipment 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.

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.

274SAFETY
Anti-Lock Brake System (ABS) Warning
Light
The yellow ABS Warning Light will turn on when
the ignition is placed in the ON/RUN mode and
may stay on for as long as four seconds.
If the ABS 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 ABS Warning Light is on.
If the ABS Warning Light is on, the brake system
should be serviced as soon as possible to
restore the benefits of Anti-Lock brakes. If the
ABS Warning Light does not come on when the
ignition is placed in the ON/RUN mode, have
the light repaired as soon as possible.
ELECTRONIC BRAKE CONTROL (EBC)
S
YSTEM
Your vehicle is equipped with an advanced
Electronic Brake Control (EBC) system. This
system includes Anti-Lock Brake System (ABS),
Brake Assist System (BAS), Electronic Brake
Force Distribution (EBD), Hill Start Assist (HSA), Electronic Roll Mitigation (ERM), Electronic
Stability Control (ESC), and Traction Control
System (TCS). 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).
Brake Assist System (BAS)

The BAS is designed to optimize the vehicle’s
braking capability during emergency braking
maneuvers. The system detects an emergency
braking situation 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 placed in 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 functioning properly and
that immediate service is required. If the Brake
System Warning Light does not come on when
the ignition is placed in the ON/RUN mode,
have the light repaired as soon as possible.
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.

21_DPF_OM_EN_USC_t.book Page 274

SAFETY275
Electronic Brake Force Distribution (EBD)
EBD 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)
ERM anticipates the potential for wheel lift by
monitoring the driver’s steering wheel input and
the speed of the vehicle. When ERM determines
that the rate of change of the steering wheel
angle and vehicle’s speed are sufficient to
potentially cause wheel lift, it then applies the
appropriate brake and may also reduce engine
power to lessen the chance that wheel lift will
occur. ERM can only reduce the chance of
wheel lift occurring during severe or evasive
driving maneuvers; it cannot prevent wheel lift
due to other factors, such as road conditions,
leaving the roadway, or striking objects or other
vehicles.
NOTE:
ERM is disabled any time the ESC is in “Full Off”
mode (if equipped). For a complete explanation
of the available ESC modes, see Ú page 275.
Electronic Stability Control (ESC)
ESC enhances directional control and stability
of the vehicle under various driving conditions.
ESC corrects for oversteering or understeering
of the vehicle by applying the brake of the
appropriate wheel(s) to counteract the above
conditions. Engine power may also be reduced
to help the vehicle maintain the desired path.

Oversteer — when the vehicle is turning more
than appropriate for the steering wheel position.
Understeer — when the vehicle is turning less
than appropriate for the steering wheel position.
ESC uses sensors in the vehicle to determine
the vehicle path intended by the driver and
compares it to the actual path of the vehicle.
When the actual path does not match the
intended path, ESC applies the brake of the
appropriate wheel to assist in counteracting the
oversteer or understeer condition.

The ESC Activation/Malfunction Indicator Light
located in the instrument cluster will start to flash
as soon as the ESC system becomes active.
The ESC Activation/Malfunction Indicator Light
also flashes when the TCS is active. If the ESC
Activation/Malfunction 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.

WARNING!

Many factors, such as vehicle loading, road
conditions and driving conditions, influence
the chance that wheel lift or rollover may occur.
ERM cannot prevent all wheel lift or roll overs,
especially those that involve leaving the
roadway or striking objects or other vehicles.
The capabilities of an ERM-equipped vehicle
must never be exploited in a reckless or
dangerous manner which could jeopardize
the user's safety or the safety of others.

(SABs) — If Equipped
Your vehicle may be equipped with
Supplemental Seat-Mounted Side Air Bags
(SABs). If your vehicle is equipped with
Supplemental Seat-Mounted Side Air Bags
(SABs), please refer to the information below.
Supplemental Seat-Mounted Side Air Bags
(SABs) are located in the outboard side of the
front seats. The SABs are marked with “SRS
AIRBAG” or “AIRBAG” on a label or on the seat
trim on the outboard side of the seats.

Supplemental Seat-Mounted Side Air Bag Label
The SABs (if equipped with SABs) may help to
reduce the risk of occupant injury during certain
side impacts, in addition to the injury reduction
potential provided by the seat belts and body
structure.
When the SAB deploys, it opens the seam on
the outboard side of the seatback’s trim cover.
The inflating SAB deploys through the seat
seam into the space between the occupant and
the door. The SAB moves at a very high speed
and with such a high force that it could injure
occupants if they are not seated properly, or if
items are positioned in the area where the SAB
inflates. Children are at an even greater risk of
injury from a deploying air bag.

BRAKE SYSTEM
In order to ensure brake system performance,
all brake system components should be
inspected periodically Ú page 354.
Fluid Level Check — Brake Master Cylinder
The fluid level of the master cylinder should be
checked when performing under the hood
service or immediately if the brake system
warning lamp indicates system failure.

If necessary, add fluid to bring level within the
designated marks on the side of the reservoir of the
brake master cylinder. Be sure to clean the top of
the master cylinder area before removing cap.
With disc brakes the fluid level can be expected
to fall as the brake linings wear. However, an
unexpected drop in fluid level may be caused by
a leak and a system check should be conducted.

For further information Ú
page 444.
AUTOMATIC TRANSMISSION
Special Additives

The manufacturer strongly recommends against
using any special additives in the transmission.
Automatic Transmission Fluid (ATF) is an
engineered product and its performance may be
impaired by supplemental additives. Therefore,
do not add any fluid additives to the transmission.
The only exception to this policy is the use of special
dyes for diagnosing fluid leaks in six-speed
transmissions. Avoid using transmission sealers as
they may adversely affect seals.

WARNING!
Riding the brakes can lead to brake failure
and possibly a collision. Driving with your foot
resting or riding on the brake pedal can result
in abnormally high brake temperatures,
excessive lining wear, and possible brake
damage. You would not have your full braking
capacity in an emergency.WARNING!
Use only manufacturer's recommended
brake fluid Úpage 444. Using the wrong
type of brake fluid can severely damage
your brake system and/or impair its perfor -
mance. The proper type of brake fluid for
your vehicle is also identified on the original
factory installed hydraulic master cylinder
reservoir.

To avoid contamination from foreign matter
or moisture, use only new brake fluid or fluid
that has been in a tightly closed container.
Keep the master cylinder reservoir cap
secured at all times. Brake fluid in a open
container absorbs moisture from the air
resulting in a lower boiling point. This may
cause it to boil unexpectedly during hard or
prolonged braking, resulting in sudden brake
failure. This could result in a collision.

Overfilling the brake fluid reservoir can
result in spilling brake fluid on hot engine
parts, causing the brake fluid to catch fire.
Brake fluid can also damage painted and
vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
Do not allow petroleum based fluid to
contaminate the brake fluid. Brake seal
components could be damaged, causing
partial or complete brake failure. This could
result in a collision.
