Driving and Operating
Warning (Continued)
.
The hill start assist system
may not prevent the vehicle
from rolling backwards on a
hill under all load or road
conditions. Always 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.
When the vehicle is stopped on a
hill, 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.
The hill start assist system will
operate automatically under the
following conditions:
.
The transmission 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 two seconds. After
two seconds the vehicle will
begin to roll back and the hill
start assist system will stop
operating completely.
The hill start assist system will not
operate when the shift lever is
placed in the N (Neutral) or P (Park)
position or on a flat and level road.
Ride Control Systems
Traction Control/
Electronic Stability
Control
System Operation
The vehicle has a Traction Control
System (TCS) and Electronic
Stability Control, an electronic
stability control system. These
systems use various sensors to
monitor driver inputs and vehicle
motion. Under certain driving
conditions, the TCS and Electronic
Stability Control systems help to
perform the following functions:
.
Control brake pressure to reduce
wheel slip on one slipping drive
wheel so power is transferred to
a non
–
slipping drive wheel on
the same axle.
.
Control brake pressure and
engine output to reduce drive
wheel slip based on vehicle
speed (traction control function).
