System Description

INFOID:0000000009479396

• 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 is available.
