Driving If vehicle speed drops more than 16 km/h (10 mph), the speed control will cancel automatically. Resume speed with accelerator pedal. If speed control cancels after climbing the hill, reset speed by pressing and holding the SET ACCEL button to resume speeds over 50 km/h (30 mph). Automatic transmissions may shift frequently while driving up steep (Overdrive) into grades. Eliminate frequent shifting by shifting out of a lower gear. Driving on snow and ice A 4WD vehicle has advantages over 2WD vehicles in snow and ice but can skid like any other vehicle. Avoid sudden applications of power and quick changes of direction on snow and ice. Apply the accelerator slowly and steadily when starting from a full stop. If your vehicle is equipped with a Rear Anti-lock Brake System (RABS), you should be careful when braking. Front brake lock-up, on any surface, causes loss of steering control. If your vehicle is equipped with a Four Wheel Anti-lock Brake System (ABS), apply the brakes as you normally would. In order to allow the ABS to operate properly, keep steady pressure on the brake pedal. When driving on snow or ice with either braking system, allow more stopping distance and drive slower than usual. Consider using one of the lower gears.
