The hill descent control system helps maintain
vehicle speed when driving under 15-21 mph
(25-35 km/h) on steeper downhill grades. Hill
descent control is useful when engine braking
alone in 4H or 4L cannot control vehicle speed.
Hill descent control applies the vehicle brakes to
control vehicle speed allowing the driver to con-
centrate on steeringwhile reducingthe burdenof
brake and accelerator operation.
● When additional braking is required on
steep downhill roads activate the hill de-
scent control system by pushing the switch
ON, see “Hill descent control switch” in the
“Instruments and controls” section.
●
Once the system is activated the indicator
light will remain on in theinstrument panel, see
“Hill descent control system onindicator light”
in the “Instruments and controls” section.
If the accelerator or brake pedal is depressed
while the hill descent control system 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.
For the best results, when descending steep
downhill grades, the hill descent control switch
should be ON and the shift selector in 2 (Second
gear) or 1 (Low gear) for engine braking.
WARNING
● Never rely solely on the hill start assist
system to prevent the vehicle from mov-
ing backward on a hill. Always drive
carefully and attentively. Depress the
brake pedal when the vehicle is
stopped on a steep hill. Be especially
careful when stopped ona hillon frozen
or muddy roads. Failure to prevent the
vehicle from rolling backwards may re-
sult 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 standstill
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 conditions. Al-
ways be prepared to depress the brake
pedal to prevent the vehicle 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 backwards 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 selector is shifted 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
selector is shifted to N or P or on a flat and level
road.
