2-1. Driving procedures CAUTION n When braking the vehicle l 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. l If the power brake assist function does not operate, do not follow other vehicles closely and avoid downhills or sharp turns that require braking. In this case, braking is still possible, but it will require more force on the pedal than usual. Braking distance may also increase. l 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. l 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 braking distance becomes longer. Do not drive your vehicle with only a single brake system. Have your brakes fixed immediately. n 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. n If you hear a squealing or scraping noise (brake pad wear limit indicators) Have the brake pads checked and replaced by your Toyota dealer as soon as possible. Rotor damage can result if the pads are not replaced when needed. It is dangerous to drive the vehicle when the wear limits of the brake pads and/or those of the brake discs are exceeded. 2 When driving 163
