& 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 .
! Electronic Brake booster s07ak0207
The vehicle is equipped with an electronic brake booster to provide additional braking force . Do not turn off the ignition switch 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 .
NOTE
When the following operations are performed , an operating sound from the electronic brake boost control module may be heard . This is not a malfunction .
. The brake pedal was operated . . The driver ’ s door was opened . . The EyeSight function was activated . . Several minutes have passed after the engine stopped .
! Supplemental booster function when pressure fails s07ak020701
If there is a malfunction in the braking system , the power for the braking will be stored by controlling the hydraulic pressure of the VDC system .
When the brake pedal is depressed while the supplemental booster function is operating , an operation sound and brake pedal vibration may be generated .
! Brake assist system
WARNING
s07ak0203
Do not be overconfident about the brake assist . It is not a system that brings more braking ability to the vehicle beyond its braking capability . Always use the utmost care
