LIMITATIONS - VEHICLES
WITH: ADAPTIVE CRUISE
CONTROL WITH STOP AND GO
Sensor Limitations WARNING: 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. WARNING:
If the system
malfunctions, have your vehicle checked
as soon as possible. WARNING:
Large contrasts in
outside lighting can limit sensor
performance. WARNING:
The system only warns
of vehicles detected by the radar sensor.
In some cases there may be no warning
or a delayed warning. Apply the brakes
when necessary. Failure to follow this
instruction could result in personal injury
or death. WARNING:
The system may not
detect stationary or slow moving
vehicles below
6 mph (10 km/h). WARNING:
The system does not
detect pedestrians or objects in the road. WARNING:
The system does not
detect oncoming vehicles in the same
lane. WARNING:
The system may not
operate properly if the sensor is blocked.
Keep the windshield free from
obstruction. WARNING:
The sensor may
incorrectly track lane markings as other
structures or objects. This can result in
a false or missed warning. The camera is mounted on the windshield
behind the interior mirror.

The radar sensor is in the lower grille.
Note:
You cannot see the sensor. It is
behind a fascia panel.
Note: Keep the front of your vehicle free of
dirt, metal badges or objects. Vehicle front
protectors, aftermarket lights, additional
paint or plastic coatings could also degrade
sensor performance.
A message displays if something obstructs
the camera or the sensor. When something
blocks the sensor, the system cannot
detect a vehicle ahead and does not
function. See Adaptive Cruise Control
– Information Messages (page 256).
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 image does
not illuminate if the system does not
detect a vehicle in front of you. 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.
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.

Following a Vehicle
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 the gap setting.
Note:
When you are following a vehicle and
you switch on a turn signal lamp, adaptive
cruise control may provide a small,
temporary acceleration to help you pass.
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
down your vehicle to maintain a safe gap
distance from the vehicle in front of you.
The system only applies limited braking.
You can override the system by applying
the brakes.
Note: The brakes may emit noise when
applied by the system.
If the system determines that its maximum
braking level is not sufficient, an audible
warning sounds, a message appears in the
instrument cluster display and an indicator
flashes when the system continues to
brake. Take immediate action.
CANCELING THE SET SPEED Press the button or tap the brake
pedal.
The set speed does not erase.
RESUMING THE SET SPEED Press the button. 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.
Note:
Only use resume if you are aware of
the set speed and intend to return to it.
Resuming the Set Speed from a
Complete Stop
If your vehicle follows a vehicle to a
complete stop and remains stationary for
less than three seconds, your vehicle
accelerates from a stationary position to
follow the vehicle ahead. If your vehicle follows a vehicle
to a complete stop and remains
stationary for more than three
seconds, press and release the button or
press the accelerator pedal to follow the
vehicle ahead.
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.
Use the accelerator pedal to intentionally
exceed the set speed limit.
When you override the system, the green
indicator illuminates and the vehicle icon
does not appear in the instrument cluster
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.
