2-1. Driving procedures CAUTION 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. NOTICE n When driving the vehicle l Do not depress the accelerator and brake pedals at the same time during driving. If the brake pedal is depressed while driving with the accelerator pedal depressed, driving torque may be restrained. l Do not use the accelerator pedal or depress the accelerator and brake pedals together to hold the vehicle on a hill. n When parking the vehicle Always put the shift lever in P. Failure to do so may cause the vehicle to move or the vehicle may accelerate suddenly if the accelerator pedal is accidentally depressed. n Avoiding damage to vehicle parts l Do not turn the steering wheel fully in either direction and hold it there for a long time. Doing so may damage the power steering motor. l When driving over bumps in the road, drive as slowly as possible to avoid damag- ing the wheels, underside of the vehicle, etc. n If you hear a squealing or scraping noise (brake pad wear limit indicators) Have your Lexus dealer check and replace the brake pads as soon as possible. Rotor damage can result if the pads are not replaced when needed. Moderate levels of brake pad and disc wear allow enhanced front braking power. As a result, the discs may wear more quickly than conventional brake discs. Therefore, when replacing the brake pads, Lexus recommends that you also have the thickness of the discs measured. It is dangerous to drive the vehicle when the wear limits of the brake pads and/or those of the brake discs are exceeded. 128
