Braking
S07AK
& Braking tips
S07AK01
WARNING
Never rest your foot on the brake
pedal while driving. This can cause
dangerous overheating of the
brakes and needless wear on the
brake pads and linings.
! When the brakes get wet
S07AK0101
When driving in rain or after washing the
vehicle, the brakes may get wet. As a
result, brake stopping distance will be
longer. To dry the brakes, drive the vehicle
at a safe speed while lightly depressing the
brake pedal to heat up the brakes.
! Use of engine braking
S07AK0102
Remember to make use of engine braking
in addition to foot braking. When descend-
ing a grade, if only the foot brake is used,
the brakes may start working improperly
because of brake fluid overheating,
caused by overheated brake pads. To help
prevent this, shift into a lower gear to get
stronger engine braking.
! Braking when a tire is punctured
S07AK0103
Do not depress the brake pedal suddenly
when a tire is punctured. This could cause
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
S07AK02
! Two separate circuits
S07AK0201
Your vehicle has two separate circuit brake
systems. Each circuit works diagonally
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
S07AK0202
The brake booster uses an engine mani-
fold vacuum and a vacuum pump to assist
braking force. Do not turn off the engine
while driving because that will turn off the
brake booster, resulting 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
S07AK0205
While the ignition switch is turned “ON”
and the engine is running, the supple-
mental booster function operates when the
brake booster performance is decreased
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
S07AK0203
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.
CAUTION
When you need to brake suddenly,
continue depressing the brake pedal
strongly to bring the effect of the
brake assist.
