Hill descent control system (if so equipped)
Starting and driving 5-181
The hill descent control system helps maintain vehicle speed when driving under 15 mph (25 km/h) on steeper downhill grades. Hill descent control is useful when engine braking alone cannot control ve- hicle speed. Hill descent control applies the vehicle brakes to control vehicle speed al- lowing the driver to concentrate on steer- ing while reducing the burden of brake and accelerator operation. If the hill descent control system ON indica- tor light is blinking, the hill descent control is engaged; however, the hill descent con- trol will not control the vehicle speed. • Once the system is activated, the indica-
tor light will remain on in the instrument panel. For additional information, see “Hill descent control system ON indicator light” (P. 2-17).
If the accelerator or brake pedal is de- pressed while the hill descent control sys- tem is on, the system will stop operating temporarily. As soon as the accelerator or brake pedal is released, the hill descent control system begins to function again if the hill descent control operating condi- tions are fulfilled.
HILL START ASSIST SYSTEM
WARNING
• Never rely solely on the hill start as-
sist system to prevent the vehicle from moving backward on a hill. Al- ways drive carefully and attentively. Depress the brake pedal when the vehicle is stopped on a steep hill. Be especially careful when stopped on a hill on frozen or muddy roads. Failure to prevent the vehicle from rolling backwards may result in a loss of control of the vehicle and possible serious injury or death.
• The hill start assist system is not de- signed to hold the vehicle at a stand- still on a hill. Depress the brake pedal when the vehicle is stopped on a steep hill. Failure to do so may cause the vehicle to roll backwards and may result in a collision or serious personal injury.
• The hill start assist may not prevent the vehicle from rolling backwards on a hill under all load or road condi- tions. Always be prepared to depress the brake pedal to prevent the ve- hicle from rolling backwards. Failure to do so may result in a collision or serious personal injury.
The hill start assist system automatically keeps the brakes applied to help prevent the vehicle from rolling backward in the time it takes the driver to release the brake pedal and apply the accelerator when the vehicle is stopped on a hill. Hill start assist will operate automatically under the following conditions: • The shift lever is moved to a forward or
reverse gear. • The vehicle is stopped completely on a
hill by applying the brake. The maximum holding time is 2 seconds. After 2 seconds the vehicle will begin to roll back and hill start assist will stop operating completely. Hill start assist will not operate when the shift position is moved to N (Neutral) or P (Park), or on a flat and level road.
