▼ Braking when a tire is punctured 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
▼ Two separate circuits
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.
▼ Brake booster
The brake booster uses vacuum pump system 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, however, you will have to depress the pedal much harder than normal 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 supplemental 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 operating, 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 capability. Always use the utmost care when driving regarding vehicle speed and safe distance.
