active, the speedometer may vary slightly
from the set speed displayed in the
information display.

1.

Drive to desired speed.

2. Press SET+ or SET-.
3. A green indicator light, the current gap

setting and your set speed appear in

5. A vehicle image illuminates if the

system detects a vehicle in front of you.

Following a Vehicle

WARNINGS

When following a vehicle, your
vehicle does not decelerate
automatically to a stop, nor does

your vehicle always decelerate quickly
enough to avoid a crash without driver
intervention. Always apply the brakes when
necessary. Failing to do so may result in a
crash, serious injury or death.

Adaptive cruise control only warns
of vehicles detected by the radar
sensor. In some cases there may be

no warning or a delayed warning. You
should always apply the brakes when
necessary. Failure to do so may result in a
crash, serious injury or death.

Note: When you are following a vehicle and
you switch on a direction indicator, adaptive
cruise control may provide a small
temporary acceleration to help you pass.

Note: The brakes may emit noise when
applied by the system.

When a vehicle ahead of you enters the
same lane or a slower vehicle is ahead in
the same lane, the vehicle speed adjusts
to maintain a preset gap distance. A
vehicle graphic illuminates in the
instrument cluster. A vehicle graphic
illuminates in the instrument cluster.

Your vehicle maintains a consistent gap
from the vehicle ahead until:
•

The vehicle in front of you accelerates
to a speed above the set speed.

•

The vehicle in front of you moves out
of the lane you are in.

•

You set a new gap distance.

The system applies the brakes to slow your
vehicle to maintain a safe gap distance
from the vehicle in front. The system only
applies limited braking. You can override
the system by applying the brakes.

(If Equipped)

If the system determines that its maximum
braking level will not be sufficient, an
audible warning sounds when the system
continues to brake. A red warning bar
displays on the windshield and you must
take immediate action.

Setting the Gap Distance

Note: The gap setting is time dependent
and therefore the distance adjusts with your
vehicle speed.

Note: It is your responsibility to select a gap
appropriate to the driving conditions.

You can decrease or increase the distance
between your vehicle and the vehicle in
front by pressing the gap control.

Overriding the Set Speed

WARNING

If you override the system by pressing
the accelerator pedal, it does not
automatically apply the brakes to

maintain a gap from any vehicle ahead.

When you press the accelerator pedal, you
override the set speed and gap distance.

E144529

When you override the system,
the green indicator light
illuminates and the vehicle

image does not appear in the information
display.

The system resumes operation when you
release the accelerator pedal. The vehicle
speed decreases to the set speed, or a
lower speed if following a slower vehicle.

(If Equipped)

Changing the Set Speed

•

Press SET+ or SET- to change the set
speed in small increments.

•

Press the accelerator or brake pedal
until you reach the desired speed. Press
SET+ or SET-.

•

Press and hold SET+ or SET- to
change the set speed in large
increments. Release the control when
you reach the desired speed.

The system may apply the brakes to slow
the vehicle to the new set speed. The set
speed displays continuously in the
information display when the system is
active.

Canceling the Set Speed

Press CNCL or tap the brake pedal. The
set speed does not erase.

Resuming the Set Speed

Note: Only use resume if you are aware of
the set speed and intend to return to it.

Press RES. Your vehicle speed returns to
the previously set speed and gap setting.
The set speed displays continuously in the
information display when the system is
active.

Automatic Cancellation

Note: If the engine speed drops too low, an
audible warning sounds and a message
appears in the information display.
Automatic braking releases.

Hilly Condition and Trailer Tow
Usage

Note: An audible alarm sounds and the
system shuts down if it applies brakes for
an extended period of time. This allows the
brakes to cool. The system functions
normally again after the brakes cool.

Note: When towing with adaptive cruise
control, switch on Tow/Haul Mode and
Diesel Engine Brake.

Note: Tow/Haul mode increases the time
gaps and allows more distance for braking.

Select a lower gear when the system is
active in situations such as prolonged
downhill driving on steep grades, for
example in mountainous areas. The
system needs additional engine braking in
these situations to reduce the load on the
vehicle’s regular brake system to prevent
it from overheating.

Switching Adaptive Cruise Control
Off

Note: You erase the set speed and gap
setting when you switch the system off.

Press OFF when the system is in standby
mode, or switch the ignition off.

Detection Issues

WARNINGS

On rare occasions, detection issues
can occur due to the road
infrastructures, for example bridges,

tunnels and safety barriers. In these cases,
the system may brake late or
unexpectedly. At all times, you are
responsible for controlling your vehicle,
supervising the system and intervening, if
required.

If the system malfunctions, have your
vehicle checked as soon as possible.

The radar sensor has a limited field of view.
It may not detect vehicles at all or detect
a vehicle later than expected in some
situations. The lead vehicle graphic does
not illuminate if the system does not
detect a vehicle in front of you.

(If Equipped)

E71621

Detection issues can occur:

When driving on a different line
than the vehicle in front.

A

With vehicles that edge into your
lane. The system can only detect
these vehicles once they move
fully into your lane.

B

There may be issues with the
detection of vehicles in front
when driving into and coming out
of a bend or curve in the road.

C

In these cases, the system may brake late
or unexpectedly. You should stay alert and
take action when necessary.

If something hits the front end of your
vehicle or damage occurs, the
radar-sensing zone may change. This could
cause missed or false vehicle detection.

System Not Available

Note: If you disable electronic stability
control, adaptive cruise control is not
available.

The system may not turn on if there is:
•

A blocked sensor.

•

High brake temperature.

•

A failure in the system or a related
system.

Blocked Sensor

E183741

Note: You cannot see the sensor. It is
behind a fascia panel.

A message displays if something obstructs
the radar signals from the sensor. The
sensor is in the lower grille. The system
cannot detect a vehicle ahead and does
not function when something blocks the
sensor.
