HILL DESCENT CONTROL
HILL DESCENT CONTROL
System Description
INFOID:0000000005275245
• The hill descent control system will help maintain vehicle speed when driving under 25-35 km/h (15-21 MPH)
on steeper downhill grades. Hill descent control will provide braking allowing the driver to concentrate on
steering while reducing the burden of brake and accelerator operation.
• To operate the system, set the 4WD switch to 4H or 4LO and push the hill descent control switch. The hill
descent control indicator in the combination meter will turn on. While hill descent control is operating, the
stop/tail lamps will illuminate.
• If the accelerator or brake pedal is depressed while the hill descent control system is on, the system will stop
operating.
• During hill descent control operation, a mechanical noise may be heard. This is normal.
• Electrical system diagnosis by CONSULT-III is available.
