Cruise Control
With cruise control, a speed of about 40 km/h (25 mph)
or more can be maintained without keeping your foot on
the accelerator. Cruise control does not work at speeds
below about 40 km/h (25 mph).
If the brakes are applied, the cruise control shuts off.
{WARNING:
Cruise control can be dangerous where you
cannot drive safely at a steady speed. So, do not
use the cruise control on winding roads or in
heavy traffic.
Cruise control can be dangerous on slippery
roads. On such roads, fast changes in tire traction
can cause excessive wheel slip, and you could
lose control. Do not use cruise control on slippery
roads.If the vehicle is in cruise control when the Traction
Control System (TCS) begins to limit wheel spin or
the stability control system activates, the cruise control
automatically disengages. See
Traction Control System
(TCS)
on page 5‑9and StabiliTrak®Systemon
page 5‑6or Enhanced StabiliTrak®on page 5‑7.
When road conditions allow you to safely use it again,
the cruise control can be turned back on.
These controls are
located on the end of
the multifunction lever.
9 (Off): Turns the system off.
R (On): Turns the system on.
+ (Resume/Accelerate): Use this position to make
the vehicle resume to a previously set speed or to
accelerate.

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
The cruise control set speed is erased from memory by
moving the cruise control switch to
9or if the ignition
is turned off.
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.

WARNING: (Continued)
.On slippery roads, fast changes in tire traction
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.
9 (Off): Turns the system off.
R (On): Turns the system on.
S (Resume/Increase): Use this position to make the
vehicle resume a previously set speed or increase the
set speed when Adaptive Cruise Control is already
active.
T (Set/Decrease): Press to set the speed or to
decrease the set speed when Adaptive Cruise Control
is already active.
[(Cancel): Press to disengage cruise control without
erasing the set speed from memory.

United States version
shown, Canada similar This symbol appears on
the Head-Up Display
(HUD) to indicate that
Adaptive Cruise Control
is active. The number
indicates the set speed.
See Head-Up Display (HUD)
on page 4‑38for more
information.
Make sure the set speed is visible on the HUD so you
know the speed your vehicle will accelerate to if a
vehicle is not detected in your path. Keep in mind
speed limits, surrounding traffic speeds, and weather
conditions when adjusting your set speed.
If your vehicle is in Adaptive Cruise Control when the
traction control system begins to limit wheel spin, the
Adaptive Cruise Control will automatically disengage.
See Traction Control System (TCS)
on page 5‑9,
StabiliTrak®Systemon page 5‑6or Enhanced
StabiliTrak®on page 5‑7. When road conditions allow
you to safely use it again, the Adaptive Cruise Control
can be turned back on.
Resuming a Set Speed
If the Adaptive Cruise Control is set at a desired speed
and then the brakes are applied, the adaptive cruise
control is disengaged without erasing the set speed
from memory.
Once the vehicle reaches about 48 km/h (30 mph) or
more, move the Adaptive Cruise Control switch briefly
from
RtoS. The vehicle returns to the previous set
speed and stays there.
Increasing Set Speed While Using Adaptive
Cruise Control
If the Adaptive Cruise Control system is already
activated,
.PressTat the end of the lever until the desired
speed is reached, then release it and the
accelerator pedal.
.Move the Adaptive Cruise Control switch
from
RtoS. Hold it there until the desired set
speed is displayed in the HUD, then release the
switch.

.To increase the set speed in small amounts, move
the switch briefly to resume/increase. Each time
this is done, the vehicle set speed increases by
about 1.6 km/h (1 mph).
Your vehicle will not reach the set speed until the
system determines there is no vehicle in front of you.
At that point, your vehicle speed will increase to the set
speed.
Decreasing Set Speed While Using
Adaptive Cruise Control
If the Adaptive Cruise Control system is already
activated,
.PressTat the end of the lever until the lower
speed desired is reached, then release the button.
.To slow down in small amounts, briefly
press
T. Each time this is done, the vehicle
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.

The HUD controls are located to the left of the steering
wheel on the DIC control panel.
Off:Turn the brightness control knob fully
counterclockwise to turn the HUD display off.
~ (Head-Up Display): Press to move the HUD display
up or down on the windshield. HUD cannot be adjusted
side‐to‐side. Brightness Control:
Press the knob on the center of
the DIC control panel to extend and then pull the knob
until is completely extended. Turn the knob clockwise or
counterclockwise to increase or decrease the
brightness of the HUD display.
To adjust the HUD so it can be seen properly:
1. Adjust the seat to a comfortable driving position, before adjusting the HUD position.
2. Start the engine.
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.
