Side-Wind Stabilization
The system applies the brakes on one side
of your vehicle to reduce the effect of a
sudden side-wind gust on your vehicle's
path. When the system turns on, the
stability and traction control light flashes,
and a message may appear in the
information display. You may notice a
slight deceleration and may still need to
make a steering correction to maintain the
intended vehicle path. The system does
not turn on for a continuous side-wind or
during turns.
Traction Control
The system enhances your vehicle's ability
to maintain traction of the wheels by
detecting and controlling wheel spin. See
Using Traction Control (page 180). Vehicle without stability control
skidding off its intended route.

PRINCIPLE OF OPERATION
WARNING: To help avoid personal
injury, always use caution when in
reverse (R) and when using the sensing
system. WARNING:
The system may not
detect objects with surfaces that absorb
reflection. Always drive with due care
and attention. Failure to take care may
result in a crash. WARNING: Traffic control systems,
inclement weather, air brakes, external
motors and fans may affect the correct
operation of the sensing system. This
may cause reduced performance or false
alerts. WARNING:
The system may not
detect small or moving objects,
particularly those close to the ground. WARNING:
If damage occurs in the
immediate area surrounding the sensor,
have your vehicle checked as soon as
possible. WARNING:
The parking aid system
can only assist you to detect objects
when your vehicle is moving at parking
speeds. To help avoid personal injury you
must take care when using the parking
aid system. WARNING:
In cold and severe
weather conditions the system may not
function. Rain, snow and spray can all
limit sensor performance. WARNING:
The system may not
function if the sensor is blocked. Note:
If your vehicle has MyKey ™, the
sensing system cannot be switched off
when a MyKey ™ is present.
See Principle
of Operation (page 70).
Note: Do not clean the sensors with sharp
objects.
Note: If your vehicle sustains damage to
the bumper or fascia and you leave it
misaligned or bent, the sensing zone may
be altered causing inaccurate measurement
of obstacles or false alerts.
Note: Certain add-on devices installed
around the bumper or fascia may create
false alerts. For example, large trailer
hitches, bike or surfboard racks, license plate
brackets, bumper covers or any other device
that may block the normal detection zone
of the system. Remove the add-on device
to prevent false alerts.
Note: When you connect a trailer to your
vehicle, the rear parking aid may detect the
trailer and therefore provide an alert. Disable
the rear parking aid when you connect a
trailer to prevent the alert.
The sensing system warns you of obstacles
within a certain range of your vehicle. The
system turns on when you switch the
ignition on.
You can switch the system off through the
information display menu or from the
pop-up message that appears once you
shift the transmission into reverse (R). See
General Information
(page 115). If your
vehicle has a parking aid button, you can
switch the system off by pressing the
button. The system turns on when you
switch the ignition on.
