4WD CONTROL (IF EQUIPPED)
This control operates the 4WD.
Refer to the Driving chapter for
more information.
REVERSE SENSING SYSTEM (IF EQUIPPED)
The reverse sensing system (RSS) sounds a tone to warn the driver of
obstacles near the rear bumper when the reverse gear is selected.
To help avoid personal injury, please read and understand the
limitations on the reverse sensing system described below.
Reverse sensing is only an assist for some (generally large and fixed)
objects when moving in reverse on a flat surface at “parking speeds” of
approximately 6 km/h (4 mph) or less. The weather may also affect the
function of RSS. RSS may have reduced performance, or be activated
in inclement weather. It is the driver’s responsibility for ensuring that
their path is clear when operating the vehicle.
To help avoid personal injury, always use caution when in
reverse and when using the reverse sensing system.
