06 Starting and driving Brake system Brake lights The brake lights come on automatically when the brakes are applied. WARNING WARNING • Adaptive brake lights The adaptive brake lights activate in the event of sudden braking or if the ABS system is activated. This function causes an additional taillight on each side of the vehicle to illuminate to help alert vehicles traveling behind. The adaptive brake lights activate if: If the vehicle has been driven immediately prior to a brake pad inspection, the wheel hub, brake components, etc., will be very hot. Allow time for these components to cool before carrying out the inspection. Apply the parking brake and put the gear selector in the Park (P) position. Block the wheels standing on the ground, use rigid wooden blocks or large stones. Use the jack intended for the vehicle when changing a tire. For any other job, use stands to support the vehicle. The jack should be kept well-greased and clean, and should not be damaged. Be sure the jack is on a firm, level, nonslippery surface. No objects should be placed between the base of jack and the ground, or between the jack and the attachment bar on the vehicle. The jack must correctly engage the jack attachment. Never allow any part of your body to be extended under a vehicle supported by a jack. 06 • • • The ABS system activates for more than approximately a half second • In the event of sudden braking while the vehicle is moving at speeds above approximately 6 mph (10 km/h) When the vehicle has come to a stop, the brake lights and additional taillights remain on for as long as the brake pedal is depressed or until braking force on the vehicle is reduced. • • Brake circuit malfunction The brake system is a hydraulic system consisting of two separate brake circuits. If a problem should occur in one of these circuits, it is still possible to stop the vehicle with the other brake circuit. If the brake pedal must be depressed farther than normal and requires greater foot pressure, the stopping distance will be longer. Brake pad inspection On vehicles equipped with a jack*, the condition of the brake pads can be checked by raising the vehicle (see page 200 for information about using the jack and removing a wheel) and performing a visual inspection of the brake pads. * Option/accessory, for more information, see Introduction. 159
