Starting and operating/Braking
a loss of control of the vehicle. Keep
driving straight ahead while gradually
reducing speed. Then slowly pull off the
road to a safe location.
& Brake system
! Two separate circuits
Your vehicle has two separate circuit
brake systems. Each circuit works diag-
onally across the vehicle. If one circuit of
the brake system should fail, the other half
of the system still works. If one circuit fails,
the brake pedal will go down much closer
to the floor than usual and you will need to
press it down much harder. And a much
longer distance will be needed to stop the
vehicle.
! Brake booster
The brake booster uses engine manifold
vacuum to assist braking force. Do not
turn off the engine while driving because
that will turn off the brake booster, result-
ing in poor braking power.
The brakes will continue to work even
when the brake booster completely stops
functioning. If this happens, you will have
to depress the pedal much harder than
during normal braking, and the braking
distance will increase.
! Supplemental booster function
when vacuum pressure fails
While the ignition switch is turned “ON”
and the engine is running, the supple-
mental booster function operates when
the brake booster performance is de-
creased due to insufficient vacuum boost.
When the brake pedal is depressed while
the supplemental booster function is oper-
ating, an operation sound and brake pedal
vibration may be generated. This is not a
malfunction.
! Brake assist system
WARNING
Do not be overconfident about the
brake assist. It is not a system that
brings more braking ability to the
vehicle beyond its braking capabil-
ity. Always use the utmost care
when driving regarding vehicle
speed and safe distance.
7-31
Brake assist is a driver assistance system.
It assists the brake power when the driver
cannot depress the brake pedal strongly
and the brake power is insufficient.
Brake assist generates the brake power
according to the speed at which the driver
depresses the brake pedal.
NOTE
When you depress the brake pedal
strongly or suddenly, the following
phenomena occur. However, even
though these occur, they do not indi-
cate any malfunctions, and the brake
assist system is operating properly.
. You might feel that the brake pedal
is applied by lighter force and gener-
ates a greater braking force.
. You might hear an ABS operating
noise from the engine compartment.
CAUTION
When you need to brake suddenly,
continue depressing the brake pedal
strongly to bring the effect of the
brake assist.
