BRAKE SYSTEM
If power assist is lost for any reason (for example,
repeated brake applications with the engine off), the
brakes will still function. However, you will experience a
substantial increase in braking effort to stop the vehicle.
If either the front or rear hydraulic system loses normal
braking capability, the remaining system will still func-
tion with some loss of overall braking effectiveness. This
will be evident by increased pedal travel during applica-
tion, greater pedal force required to slow or stop, and
activation of the “Brake Warning Light” and the “ABS
Warning Light” (if equipped) during brake use.
The brake system power assist is provided by a hydro-
boost unit which shares fluid with the power steering
system. You may experience some clicking or hissing
noises from the hydro-boost system during hard braking
conditions. NOTE: Under cold temperatures, pedal effort will be
higher than normal until the power steering fluid reaches
operating temperature.
Hydraulic Brake Assist
The brake system power assist is provided by a hydro-
boost unit which shares fluid with the power steering
system. You may experience some clicking or hissing
noises from the hydro-boost system during hard braking
conditions.
NOTE: Under cold temperatures, pedal effort will be
higher than normal until the power steering fluid reaches
operating temperature.
ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced Electronic
Brake Control system (EBC). This system includes Elec-
tronic Brake Force Distribution (EBD), Anti-Lock Brake
System (ABS), Brake Assist System (BAS), Hill Start442 STARTING AND OPERATING

For vehicles not equipped with the EVIC/DID, perform
the following steps:
1. Center the steering wheel (front wheels pointing
straight forward).
2. Shift the transmission into PARK.
3. Apply the parking brake.
4. Start the engine.
5. Rotate the steering wheel slightly more than one-half
turn to the left.
6. Push the “ESC Off” button located in the lower switch
bank below the climate control four times within
twenty seconds. The “ESC Off Indicator Light” should
turn on and turn off two times.
7. Rotate the steering wheel back to center and then an
additional slighty more than one-half turn to the right. 8. Turn the ignition switch to the OFF position and then
back to the ON position. If the sequence was com-
pleted properly, the “ESC Off Indicator Light” will
blink several times to confirm HSA is disabled.
9. Repeat these steps if you want to return this feature to
its previous setting.
Traction Control System (TCS)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, the TCS may
apply brake pressure to the spinning wheel(s) and/or
reduce engine power to provide enhanced acceleration
and stability. A feature of the TCS, Brake Limited Differ-
ential (BLD), functions similar to a limited slip differen-
tial and controls the wheel spin across a driven axle. If
one wheel on a driven axle is spinning faster than the
other, the system will apply the brake of the spinning
wheel. This will allow more engine torque to be applied 5STARTING AND OPERATING 449

to the wheel that is not spinning. BLD may remain
enabled even if TCS and ESC are in a reduced mode.
Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESC cor-
rects for oversteering or understeering of the vehicle by
applying the brake of the appropriate wheel(s) to assist in
counteracting the oversteer or understeer condition. En-
gine power may also be reduced to help the vehicle
maintain the desired path.
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 appro-
priate wheel to assist in counteracting the oversteer or
understeer condition.
• 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.
The “ESC Activation/Malfunction Indicator Light” lo-
cated 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!• Electronic Stability Control (ESC) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded by
prevailing road conditions. ESC cannot prevent (Continued)450 STARTING AND OPERATING

WARNING! (Continued)assemblies must be replaced after a collision if they
have been damaged (i.e., bent retractor, torn web-
bing, etc.).
FUSES
WARNING!• When replacing a blown fuse, always use an ap-
propriate replacement fuse with the same amp
rating as the original fuse. Never replace a fuse
with another fuse of higher amp rating. Never
replace a blown fuse with metal wires or any other
material. Failure to use proper fuses may result in
serious personal injury, fire and/or property dam-
age. (Continued) WARNING! (Continued)• Before replacing a fuse, make sure that the ignition
is off and that all the other services are switched off
and/or disengaged.
• If the replaced fuse blows again, contact an autho-
rized dealer.
• If a general protection fuse for safety systems (air
bag system, braking system), power unit systems
(engine system, gearbox system) or steering system
blows, contact an authorized dealer.
