2-1. Driving procedures
CAUTION
When braking the vehicle
■
When the brakes are wet, drive more cautiously.
●
Braking distance increases when the brakes are wet, and this may cause one side
of the vehicle to brake differently than the other side. Also, the parking brake may
not securely hold the vehicle.
If the power brake assist function does not operate, do not follow other vehicles
●
closely and avoid hills or sharp turns that require braking.
In this case, braking is still possible, but the brake pedal should be depressed
more firmly than usual. Also, the braking distance will increase.
RX350: Do not pump the brake pedal if the engine stalls.
●
Each push on the brake pedal uses up the reserve for the power-assisted brakes.
RX350: The brake system consists of 2 individual hydraulic systems; if one of the
●
systems fails, the other will still operate. In this case, the brake pedal should be
depressed more firmly than usual and the braking distance will increase.
If this happens, do not drive the vehicle. Have your brakes fixed immediately.
RX450h: The brake system consists of 3 individual hydraulic systems; if one of
●
the systems fails, the others will still operate. In this case, the brake pedal should
be depressed more firmly than usual and the braking distance will increase. If this
happens, do not continue to drive the vehicle. If the brake system warning light
(red indicator) comes on together with the buzzer sound while driving, immedi-
ately stop the vehicle in a safe place and contact your Lexus dealer.
If the vehicle becomes stuck
■
Do not spin the wheels excessively when any of the tires is up in the air, or the vehi-
cle is stuck in sand, mud, etc. This may damage the driveline components or propel
the vehicle forward or backward, causing an accident.
