CAUTION

■

When taking a nap in the vehicle

Always turn the engine off. Otherwise, you may accidentally move the shift lever or

depress the accelerator pedal, which could cause an accident or fire due to engine

overheating. Additionally, if the vehicle is parked in a poorly ventilated area, exhaust

gases may collect and enter the vehicle, leading to death or a serious health hazard.

■

When braking the vehicle

●

When the brakes are wet, drive more cautiously.

Braking distance increases when the brakes are wet, and 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 brake actuator (GS460) or brake booster (GS350) does not operate, do

not follow other vehicles closely and avoid hills or sharp turns that require brak-

ing.

In this case, braking is still possible, but it will require more force on the pedal than

usual. Braking distance may also increase.

●

Do not pump the brake pedal if turning the engine off.

Each push on the brake pedal uses up the reserve for the power-assisted brakes.

●

The brake system consists of 3 (GS460) or 2 (GS350) individual hydraulic sys-

tems: 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 braking distance becomes

longer.

Do not drive your vehicle with only a single brake system. Have your brakes fixed

immediately.

■

If the vehicle becomes stuck or bogged (4WD models)

Do not spin the wheels recklessly when any of the tires is up in the air, or stuck in

sand or mud, etc. This may damage the drive system components or propel the

vehicle forward (or in another direction) and cause an accident.
