When going downhill, you might have to brake to keep
the vehicle speed down. When the brakes are applied
the cruise control is disengaged.
Ending Cruise Control
There are three ways to end cruise control.
.To disengage cruise control; step lightly on the
brake pedal.
.Press the[button on the steering wheel.
.To turn off cruise control, move the cruise control
switch to
9.
Erasing Speed Memory

Adaptive Cruise Control
If the vehicle has adaptive cruise control, read the
Radio Frequency Statementon page 8‑20before using
this feature.
Changes or modifications to this system by other than
an authorized service facility could void authorization to
use this equipment.
Adaptive Cruise Control is an enhancement to
traditional cruise control and is not a safety system.
It allows you to keep cruise control engaged in
moderate traffic conditions without having to constantly
be reset. Adaptive Cruise Control uses radar to
detect a vehicle directly ahead in your path, within a
distance of 100 m (328 ft), and operates at speeds
above 48 km/h (30 mph). When it is engaged by
the driver, the system can apply limited braking or
acceleration of the vehicle, automatically, to maintain
a selected following distance to the vehicle ahead.

can cause needless wheel spinning, and you
could lose control. Do not use cruise control
on slippery roads.
.When weather limits visibility, such as when in
fog, rain, or snow conditions, Adaptive Cruise
Control performance is limited. There may not
be enough distance to adapt to the changing
traffic conditions. Do not use cruise control
when visibility is low.
The cruise controls are
located on the end of the
multifunction lever.
The Adaptive Cruise controls are located on the left
side of the steering wheel.

set speed decreases by about 1.6 km/h (1 mph).
Selecting the Follow Distance (GAP)
When the system detects a slower moving vehicle, it
will adjust your vehicle's speed and maintain the
following distance (gap) selected.
Use the GAP button on the steering wheel to adjust
the follow distance between your vehicle and other
vehicle's.
Press the top of the button to increase the distance or
the bottom of the button to decrease the distance. The
first button press shows the current follow distance
setting on the HUD. The current following distance
setting is maintained until it is changed.
There are six follow distances to choose from. The
follow distance selection ranges from near to far
(one second to two seconds follow time). The distance
maintained for a selected follow distance varies based
on vehicle speed. The faster the vehicle speed the
further back you will follow. Consider traffic and weather
conditions when selecting the follow distance.

3. Adjust the position and brightness of the HUD display.
The brightness of the HUD display is determined by the
light conditions in the direction the vehicle is facing and
where the HUD has been positioned on the windshield.
If the vehicle is facing a dark object or a heavily shaded
area, the HUD may begin to dim because it anticipates
the vehicle entering a dark area.
When sunlight enters the HUD it can make it difficult
to see the display. The display will return to normal
brightness when the sunlight no longer enters the HUD.
Wearing polarized sunglasses could also make the
HUD display harder to see.

Sensors
The solar sensor located on the instrument panel, near
the windshield, monitors the solar heat.The interior temperature sensor located on the
instrument panel to the right of the steering wheel,
measures the temperature of the air inside the vehicle.
The climate control system uses the information from
these sensors to adjust the temperature, the fan speed
and the air delivery, in order to maintain the selected
temperature. The system may also supply cooler air to
the side of the vehicle facing the sun.
Do not cover the sensors or the automatic climate
control system will not work properly.

Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments may have
programs to inspect the on-vehicle emission control
equipment For the inspection, the emission system test
equipment is connected to the vehicle’s Data Link
Connector (DLC).
The DLC is under the instrument panel to the left of the
steering wheel. See your dealer if assistance is needed.The vehicle may not pass inspection if:
.the Malfunction Indicator Lamp is on with the
engine running, or if the light does not come on
when the ignition is turned to ON/RUN while the
engine is off.
.the critical emission control systems have not been
completely diagnosed by the system. This can
happen if the battery has recently been replaced or
if the battery has run down. The diagnostic system
evaluates critical emission control systems during
normal driving. This can take several days of
routine driving. If this has been done and the
vehicle still does not pass the inspection, your
dealer can prepare the vehicle for inspection.
