Increasing Speed While Using Cruise
Control
There are two ways to increase speed:
Use the accelerator pedal to get to the higher
speed. Press
Tat the end of the lever, then
release the button and the accelerator pedal.
The vehicle will now cruise at the higher speed.
If the accelerator pedal is held longer than
60 seconds, cruise control will turn off.
Move the cruise switch fromRtoS. Hold it there
until the desired speed is reached, and then
release the switch. To increase the vehicle speed
in small amounts, move the switch briey to
resume/accelerate. Each time this is done, the
vehicle goes about 1 mph (1.6 km/h) faster.
Reducing Speed While Using Cruise
Control

Press and hold the set button until the lower speed
desired is reached, then release it.
To slow down in small amounts, briey press the
set button. Each time this is done, the vehicle
goes about 1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase the vehicle speed.
When you take your foot off the pedal, the vehicle
slows down to the cruise control speed set earlier.
Using Cruise Control on Hills
How well your cruise control works on hills depends
upon the vehicle speed, load and the steepness of the
hills. When going up steep hills, you might have to
step on the accelerator pedal to maintain your speed.
When going downhill, you might have to brake or shift
to a lower gear to keep your vehicle’s speed down.
When the brakes are applied the cruise control turns off.
Ending Cruise Control
There are two ways to turn off the cruise control:
Step lightly on the brake pedal
Move the cruise control switch to9
Erasing Speed Memory
The cruise control set speed memory is erased when
the cruise control or the ignition is turned off.

operation of the device.
This device complies with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
1. This device may not cause interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.Changes or modications 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 it having to be constantly reset.
Adaptive Cruise Control uses radar to detect a vehicle
directly ahead in your path, within a distance of
328 ft (100 m), and operates at speeds above
25 mph (40 km/h). 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. The vehicle’s
braking during Adaptive Cruise Control is comparable to
a person applying moderate pressure to the vehicle’s
brake pedal. To disengage Adaptive Cruise Control,
apply the brake. If no vehicle is in your path, your
vehicle will react like traditional cruise control.
3-14

{CAUTION:
Adaptive Cruise Control will not apply hard braking
or bring the vehicle to a complete stop. It will not
respond to stopped vehicles, pedestrians or
animals. When you are approaching a vehicle or
object, Adaptive Cruise Control may not have time
to slow your vehicle enough to avoid a collision.
Your complete attention is always required while
driving and you should be ready to take action
and apply the brakes. For more information,
seeDefensive Driving on page 5-2.
{CAUTION:
On winding roads, Adaptive Cruise Control
may not detect a vehicle ahead. You could
crash into a vehicle ahead of you. Do not use
Adaptive Cruise Control on winding roads.
CAUTION: (Continued)
CAUTION: (Continued)

Adaptive Cruise Control may not have time to
slow your vehicle enough to avoid a crash
when you are driving in conditions where
vehicles may suddenly slow or stop ahead of
you, enter your lane, or cross your vehicle’s
path. If you are driving in these conditions, do
not use Adaptive Cruise Control. The warning
beep and alert symbol may indicate that
you are driving in conditions where Adaptive
Cruise Control should not be used.
See “Alerting the Driver” in this section.
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.
3-15

The set speed is selected by the driver. This is the
speed you will travel if there is no vehicle detected in
your path.
To set Adaptive Cruise Control, do the following:
1. Make sure the Head-Up Display (HUD) is on and
properly adjusted. You cannot engage Adaptive
Cruise Control unless the HUD is on. SeeHead-Up
Display (HUD) on page 3-31for more information.
2. Move the switch to the on position.
3. Get up to the desired speed.
4. Press
Tat the end of the lever and release
the button.
5. Take your foot off the accelerator pedal.
Once Adaptive Cruise Control is set, it might
immediately apply the brakes if it detects a vehicle
ahead that is too close or moving slower than your
vehicle.This symbol appears on
the Head-Up Display
(HUD) to indicate that
Adaptive Cruise Control
is active.
SeeHead-Up Display (HUD) on page 3-31for 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 the vehicle is in Adaptive Cruise Control when the
traction control system begins to limit wheel spin,
the Adaptive Cruise Control automatically disengages.
SeeTraction Control System (TCS) on page 5-8
andStabiliTrak
®System on page 5-6. When road
conditions allow you to safely use it again, the Adaptive
Cruise Control can be turned back on.

Increasing Set Speed While Using Adaptive
Cruise Control
There are two ways to increase the set speed:
Use the accelerator to get to the higher speed.
Press
Tat the end of the lever, then release
the button and the accelerator pedal. The vehicle
will now cruise at the higher speed.
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 briey to resume/increase. Each time
this is done, the vehicle set speed increases
by about 1 mph (1.6 km/h).
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
PressTon the end of the lever until the lower
desired speed is reached, then release the button.
To slow down in small amounts, briey press
T.
Each this is done, the set speed will be 1 mph (1.6 km/h)
slower.
Resuming a Set Speed
If the brakes are applied while the Adaptive Cruise
Control is at a set speed, this disengages the Adaptive
Cruise Control. But it does not need to be reset.
Once the vehicle reaches about 25 mph (40 km/h) or
more, move the Adaptive Cruise Control switch
briey from
RtoS. Adaptive Cruise Control will be
engaged with the speed selected previously.
3-18

Alerting the Driver
This symbol ashes on the
HUD and a warning beep
sounds when driver
action is required.
Driver action is required when:
Adaptive Cruise Control cannot apply sufficient
braking because you are approaching a vehicle
too rapidly.
The vehicle speed drops below about
20 mph (32 km/h).
A temporary condition prohibits Adaptive Cruise
Control from operating. SeeDIC Warnings and
Messages on page 3-60for more information.
A malfunction is detected in the system. SeeDIC
Warnings and Messages on page 3-60for more
information.
SeeDefensive Driving on page 5-2.
{CAUTION:
Adaptive Cruise Control has only limited braking
ability to slow your vehicle. In some cases,
Adaptive Cruise Control may not have time to slow
your vehicle enough to avoid a collision. Be ready
to take action and apply the brakes yourself.
SeeDefensive Driving on page 5-2.
Approaching and Following a Vehicle
This symbol only appears
on the HUD when a
vehicle ahead is detected
in your path.
If this symbol does not appear, or disappears briey,
Adaptive Cruise Control will not respond to vehicles you
may see ahead.
3-20

{CAUTION:
When the Adaptive Cruise Control radar is blocked
by snow, ice, or dirt, it may not detect a vehicle
ahead. Adaptive Cruise Control may not have time
to slow your vehicle enough to avoid a collision.
Do not use Adaptive Cruise Control when the
radar is blocked by snow, ice, or dirt. Keep your
radar clean. See “Cleaning the System” later in
this section.
Adaptive Cruise Control automatically slows the vehicle
down when approaching a slower moving vehicle.
It then adjusts your speed to follow the vehicle in front
at the selected following distance. Your speed increases
or decreases to follow the vehicle in front of you, but
will not exceed the set speed. It may apply limited
braking, if necessary. When braking is active, the brake
lights come on. It may feel or sound different than if
you were applying the brakes yourself. This is normal.
Stationary or Very Slow-Moving Objects
{CAUTION:
Adaptive Cruise Control may not detect and react
to stationary or slow-moving vehicles or other
objects ahead of you. You could crash into an
object ahead of you. Do not use Adaptive Cruise
Control when approaching stationary or
slow-moving vehicles or other objects.
{CAUTION:
Adaptive Cruise Control may not detect and react
to stationary or slow-moving vehicles or other
objects ahead of you. Your vehicle may accelerate
toward objects, such as a stopped vehicle that
suddenly appears after the lead vehicle changes
lanes. Your complete attention is always required
while driving and you should be ready to take
action and apply the brakes.
3-21

Low-Speed Deactivation
If your speed falls below 20 mph (32 km/h) while
following a vehicle ahead, Adaptive Cruise Control
begins to disengage. The driver alert symbol on
the HUD ashes and the warning beep sounds.
The driver must take action since Adaptive Cruise
Control will not slow the vehicle to a stop.
Passing a Vehicle
To increase speed to pass a vehicle, use the accelerator
pedal. While your foot is on the accelerator pedal, the
system will not automatically apply the brakes. Once
you pass the vehicle and remove your foot from
the accelerator pedal, Adaptive Cruise Control returns
to normal operation and the brakes can be applied,
if needed.
{CAUTION:
If you rest your foot on the accelerator pedal, the
system will not automatically apply the brakes.
You could crash into a vehicle ahead of you.
Do not rest your foot on the accelerator pedal
when using Adaptive Cruise Control.
Curves in the Road
{CAUTION:
Due to Adaptive Cruise Control limitations in
curves, it may respond to a vehicle in another
lane, or may not have time to react to a vehicle in
your lane. You could crash into a vehicle ahead of
you, or lose control of your vehicle. Give extra
attention in curves and be ready to use the brakes
if necessary. Select an appropriate speed while
driving in curves.
Adaptive Cruise Control might operate differently in a
sharp curve. It might reduce your speed if the curve is
too sharp. The TIGHT CURVE message will also display
on the HUD. SeeHead-Up Display (HUD) on page 3-31
for more information.
