Anti-lock braking system (ABS)

The ABS system helps to improve vehicle
control (stopping and steering) during severe
braking conditions by limiting brake lockup.
When the system "senses" impending lockup,
braking pressure is automatically modulated
in order to help prevent lockup that could
lead to a skid.
The system performs a brief self-diagnostic
test when the engine has been started and
driver releases the brake pedal. Another auto-
matic test may be performed when the vehi-
cle first reaches a speed of approximately
6 mph (10 km/h). The brake pedal will pulsate
several times and a sound may be audible
from the ABS control module, which is nor-
mal.

Brake lights

The brake lights come on automatically when
the brakes are applied.
Adaptive brake lights
The adaptive brake lights activate in the event
of sudden braking or if the ABS system is
activated. This function causes an additional
taillight on each side of the vehicle to illumi-
nate to help alert vehicles traveling behind.
The adaptive brake lights activate if:
•
The ABS system activates for more than
approximately a half second
•
In the event of sudden braking while the
vehicle is moving at speeds above
approximately 6 mph (10 km/h).
When the vehicle has come to a stop, the
brake lights and additional taillights remain on
for as long as the brake pedal is depressed or
until braking force on the vehicle is reduced.

08 Starting and driving
Emergency Brake Assistance (EBA)
EBA is designed to provide full brake effect
immediately in the event of sudden, hard
braking.
Emergency Brake Assistance
The EBA system is activated by the speed
with which the brake pedal is depressed.
When the EBA system is activated, the brake
pedal will go down and pressure in the brake
system immediately increases to the maxi-
mum level. Maintain full pressure on the
brake pedal in order to utilize the system
completely. EBA is automatically deactivated
when the brake pedal is released.
NOTE
•
When the EBA system is activated, the
brake pedal will go down and pressure
in the brake system immediately
increases to the maximum level. You
must maintain full pressure on the
brake pedal in order to utilize the sys-
tem completely. There will be no brak-
ing effect if the pedal is released. EBA
is automatically deactivated when the
brake pedal is released.
•
When the vehicle has been parked for
some time, the brake pedal may sink
more than usual when the engine is
started. This is normal and the pedal
will return to its usual position when it
is released.
