Brakes
Electric Brake Boost
Vehicles equipped with electric brake boost
have hydraulic brake circuits that are
electronically controlled when the brake pedal
is applied during normal operation. The system
performs routine tests and turns off within
afew minutes after the vehicle is turned off.
Noise may be heard during this time. If the
brake pedal is pressed during the tests or
when the electric brake boost system is off,
anoticeable change in pedal force and travel
may be felt. This is normal.
Antilock Brake System (ABS)
The Antilock Brake System (ABS) helps prevent
abraking skid and maintain steering while
braking hard.
If there is aproblem with ABS, this warning
li
ght stays on. See Antilock Brake System (ABS)
Warning Light 3117.
ABS does not change the time needed to get
afoot on the brake pedal and does not always
decrease stopping distance. If you get too
close to the vehicle ahead, there will not be
enough time to apply the brakes if that vehicle
suddenly slows or stops. Always leave enough
room ahead to stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold the brake
pedal down firmly. Hearing and feeling ABS
operate is normal.
Braking in Emergencies
ABS allows steering and braking at the same
time. In many emergencies, steering can help
even more than braking.
Electric Parking Brake
The Electric Parking Brake (EPB) can be applied
when the vehicle is off. If there is not enough
electrical power, the EPB cannot be applied or
released. To prevent draining the battery, avoid
unnecessary repeated cycles of the EPB.
The system has ared EPB status light and
an amber service EPB warning light. See
Electric Parking Brake Light 3116 and Service
Electric Parking Brake Light 3116. There are
also parking brake-related Driver Information
Center (DIC) messages.
Before leaving the vehicle, check the red EPB
status light to ensure that the EPB is applied.
