In addition, when the master warning light comes on, and the
message “CHECK VGRS” or “CHECK P/S” appears on the
multi
−
information display, the system will not be temporarily
functioning. Although it is no problem in driving as usual, have
your vehicle checked by your Lexus dealer as soon as
possible.
CAUTION
Do not overestimate the vehicle dynamics integrated
management. Even when this management is
functional, there is a limit to vehicle stability, and
irresponsible driving may lead to an accident. When
driving, you should always pay attention to your speed
and keep a safe distance between your vehicle and the
vehicle in front.
BRAKE SYSTEM
GS430:
This brake system has 3 independent hydraulic circuits. If any
circuits should fail, the other will still work. However, the pedal
will be harder to press, and your stopping distance will
increase. Also, the brake system warning light (red) may come
on.
GS300:
The tandem master cylinder brake system is a hydraulic
system with two separate sub
−
systems. If either sub
−
system
should fail, the other will still work. However, the pedal will be
harder to press, and your stopping distance will increase. Also,
the brake system warning light (red) may come on.
CAUTION
Do not drive your vehicle with only a single brake
system. Have your brakes fixed immediately.
Brake actuator (GS430)
The brake actuator uses brake fluid pressurized by the pump
to power
−
assist the brakes. If the brake actuator fails during
driving, the brake system warning light (red) comes on and the
buzzer sounds continuously. In this case, the brakes may not
work properly. If the brake system warning light comes on,
immediately stop your vehicle and contact your Lexus dealer.
