Driving in the rain CAUTION D Do not drive in excess of the speed limit. Even if the legal speed limit permits it, do not drive over 140 km/h (85 mph) unless your vehicle has high−speed capability tires. Driving over 140 km/h (85 mph) may result in tire failure, loss of control and possible injury. Be sure to consult a tire dealer to determine whether the tires on your vehicle are high−speed capability tires or not before driving at such speeds. Driving on a slippery road surface Drive carefully when it is raining, because visibility will be reduced, the windows may become fogged−up, and the road will be slippery. D Before driving off, make sure the parking brake is fully released and the parking brake reminder light is off. D Drive carefully when it starts to rain, because the road surface will be especially slippery. D Do not leave your vehicle unattended with the "READY" light on. D Do not rest your foot on the brake pedal while driving. It can cause dangerous overheating, needless wear, and poor fuel economy. D Refrain from high speeds when driving on an expressway in the rain, because there may be a layer of water between the tires and the road surface, preventing the steering and brakes from operating properly. D To drive down a long or steep hill, reduce your speed and downshift. Remember, if you ride the brakes excessively, they may overheat and not work properly. D Do not continue normal driving when the brakes are wet. If they are wet, your vehicle will require a longer stopping distance, and it may pull to one side when the brakes are applied. Also, the parking brake will not hold the vehicle securely. D Be careful when accelerating or braking on a slippery surface. Sudden acceleration or engine braking, could cause the vehicle to skid or spin. 353
