Headlamp Washer
For vehicles with headlamp washers, they are located to
the inside of the headlamps.
Press
Llocated at the end of the windshield wiper
lever, to wash the headlamps and windshield. After the
rst wash, the headlamps will be washed after the
fth press of the windshield washer button.
The headlamps must be on to be washed. If the washer
uid is low, the headlamp washers will not work.
SeeWindshield Washer on page 3-15for additional
information.
Cruise Control
With cruise control, a speed of about 25 mph (40 km/h)
or more can be maintained without keeping your foot
on the accelerator. Cruise control does not work
at speeds below about 25 mph (40 km/h).
If the brakes are applied, the cruise control shuts off.
{CAUTION:
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. SeeTraction Control System
(TCS) on page 4-10andStabiliTrak
®System on page 4-6
orEnhanced StabiliTrak®on page 4-6. When road
conditions allow you to safely use it again, the cruise
control can be turned back on.

Resuming a Set Speed
If the cruise control is at the set speed desired and then
the brake is applied, the cruise control is disengaged.
But it does not need to be reset.
Once the vehicle speed reaches about 25 mph
(40 km/h) or more, move the cruise control switch
briey from
RtoS.
The vehicle will go back up to your chosen speed and
stay there.
If the switch is held at resume/accelerate the vehicle
keeps going faster until the switch is released or the
brake is applied. Do not hold the switch at resume/
accelerate, unless you want the vehicle to go faster.
Increasing Speed While Using Cruise
Control
There are two ways to go to a higher 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 cruise at the higher speed.
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 very
small amounts, move the switch briey to
S.
Each time this is done, the vehicle goes about
1 mph (1.6 km/h) faster.
If using the accelerator pedal and the set button at end
of the lever to increase cruise set speed, the new
set speed must be at least 5 mph higher than current
speed for this method to work. If it is not 5 mph higher,
move the cruise switch to off, then on, and then reset
the speed using the set button.
3-18

Reducing Speed While Using Cruise
Control
There are two ways to reduce your speed while using
cruise control:
PressTat the end of the lever until the lower
speed desired is reached, then release it.
To slow down in very small amounts, briey
press
T. 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 your vehicle
speed. When you take your foot off the pedal, the
vehicle slows down to the cruise control speed you
set earlier.
Using Cruise Control on Hills
How well the 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 the vehicle’s speed. When
going downhill, you might have to brake to keep the
vehicle’s speed down. Applying the brake will turn off the
cruise control. If you need to apply the brake due to the
grade of the downhill slope, you might not want to attempt
to use the cruise control feature.
Ending Cruise Control
There are three ways to end cruise control.
Step lightly on the brake pedal. This will end the
current cruise control session.
Move the cruise control switch to9to turn off the
system completely.
Press the[button on the steering wheel.
Erasing Speed Memory
The cruise control set speed memory is erased when
the cruise control or the ignition is turned off.

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 328 ft (100 m), and operates at speeds above
30 mph (48 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.
{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 4-2.
3-20

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 3-43for more information.
2. Move the switch to on.
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. The number
indicates the set speed.
SeeHead-Up Display (HUD) on page 3-43for 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.
SeeTraction Control System (TCS) on page 4-10,
StabiliTrak
®System on page 4-6orEnhanced
StabiliTrak®on page 4-6. When road conditions
allow you to safely use it again, the Adaptive
Cruise Control can be turned back on.United States version

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
PressTat the end of the lever until the lower speed
desired 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 30 mph (48 km/h)
or more, move the Adaptive Cruise Control switch briey
from
RtoS. Adaptive Cruise Control will be engaged
with the speed previously selected.
3-24

Alerting the Driver
The alert 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
25 mph (40 km/h).
A temporary condition prohibits Adaptive Cruise
Control from operating. SeeDIC Warnings and
Messages on page 3-79for more information.
A malfunction is detected in the system. SeeDIC
Warnings and Messages on page 3-79for more
information.
SeeDefensive Driving on page 4-2.
{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 4-2.
Approaching and Following a Vehicle
The vehicle ahead 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.
3-26

{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 your 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, your 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.
