The RSS automatically turns on
when the gearshift lever is placed in
R (Reverse) and the ignition is ON.
An RSS control allows the driver to
turn the RSS on and off. To turn the
RSS off, the ignition must be ON,
and the gear selector in R
(Reverse). An indicator light on the
control will illuminate when the system is turned off. If the indicator
light illuminates when the RSS is not turned off, it may indicate a failure
in the RSS. The RSS will remain off until either the RSS control is
pushed again or the ignition switch is recycled.

Keep the RSS sensors (located on the rear bumper/fascia) free
from snow, ice and large accumulations of dirt (do not clean the
sensors with sharp objects). If the sensors are covered, it will
affect the accuracy of the RSS.

If your vehicle sustains damage to the rear bumper/fascia, leaving
it misaligned or bent, the sensing zone may be altered causing
inaccurate measurement of obstacles or false alarms.

FOUR-WHEEL DRIVE (4WD) OPERATION (IF EQUIPPED)

For important information regarding safe operation of this type
of vehicle, see Preparing to drive your vehicle in this chapter.

Four–wheel drive (4WD) supplies power to all four wheels. 4WD should
not be operated on dry pavement; driveline damage may occur.

If equipped with the Electronic Shift 4WD System, and 4WD Low
is selected while the vehicle is moving, the 4WD system will not
engage. This is normal and should be no reason for concern.
