Braking
an opportunity to cool down . However , if the power steering is operated in a non-standard way which causes power assist limitation to occur too frequently , this may result in a malfunction of the power steering control system .
7-12 . Braking & Braking Tips
WARNING s07ak
s07ak01
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 .
! 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 descending 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 place .
& Brake System s07ak02
! Two separate circuits s07ak0201
Your vehicle has a dual circuit brake system . 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 .
! Vacuum brake booster ( models with the vacuum brake booster ) s07ak0202
The vacuum brake booster uses a vacuum pump to assist braking force . Do not turn off the engine while driving because that will turn off the vacuum brake booster , resulting in poor braking power .
The brakes will continue to work even when the vacuum brake booster completely stops functioning . If this happens , however , you will have to depress the pedal much harder than normal and the braking distance will increase .
