STARTING AND DRIVING
196
When your vehicle is loaded heavily or you are driving in an
unpaved road, the mode 3 or 4 will be recommended. To
provide good vehicle stability, the damping effect will be harder than
for ordinary driving mode.
With the four−wheel drive control lever at ”L”, the damping effect
suitable for off−road driving will be provided.
BRAKE SYSTEM
This brake system has 2 independent hydraulic circuits. If either
circuit should fail, the other will still work. However, the pedal will
be harder to press, and your stopping distance will be longer. Also,
the brake system warning light may come on.
CAUTION
Do not drive your vehicle with only a single brake system.
Have your brakes fixed immediately.
Brake booster
The brake booster uses brake fluid pressurized by the pump to
power−assist the brakes. If the brake booster fails during driving, the
brake system warning light comes on and buzzer sounds
continuously. In this case, the brakes may not work properly. If they
do not work well, depress the brake pedal firmly. If the brake system
warning light comes on, immediately stop your vehicle and contact
your Lexus dealer.
The brake system warning light may come on for about 60 seconds
after the engine is started. It is normal if the light goes out after a
while.
Depressing the brake pedal repeatedly may turn on the brake system
warning light and buzzer. It is normal if the light goes out and the
buzzer stops sounding after a few seconds.
