HOW DOES ADAPTIVE CRUISE
CONTROL WITH STOP AND GO
WORK
Adaptive cruise control with stop and go
uses radar and camera sensors to adjust the
speed of your vehicle to maintain a set gap
from the vehicle in front of you in the same
lane while following it to a complete stop.
You can also engage the system to follow a
vehicle in front of you and adjust set speed
while stopped.
WHAT IS ADAPTIVE CRUISE
CONTROL WITH LANE CENTERING
Adaptive cruise control with lane centering
uses radar and camera sensors to help keep
your vehicle in the lane by applying
continuous assistance steering torque input
toward the lane center on highways.
Note:The adaptive cruise control gap setting
operates normally.
WHAT IS INTELLIGENT ADAPTIVE
CRUISE CONTROL
Intelligent adaptive cruise control combines
speed sign recognition with adaptive cruise
control to adjust the cruise set speed to the
speed limit detected by the speed sign
recognition system. For example, if the speed
sign recognition system detects a 50 mph
(80 km/h) speed limit, the cruise set speed
is updated to 50 mph (80 km/h) +/- the
driver's selected speed offset.
Note:The adaptive cruise control gap setting
operates normally.

(page 306).
WARNING: Do not use the system
when towing a trailer. Failure to follow this
instruction could result in the loss of
control of your vehicle, personal injury or
death.
WARNING: Do not use the system if
any changes or modifications to the
steering wheel have been made. Any
changes or modifications to the steering

Adaptive Cruise Control (If Equipped)

Hilly Condition Usage
You should 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.
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.

LIMITATIONS - VEHICLES WITH:
ADAPTIVE CRUISE CONTROL
WITH LANE CENTERING
Adaptive cruise control limitations apply to
lane centering unless stated otherwise or
contradicted by a lane centering limitation.
See Adaptive Cruise Control Limitations
(page 307).The system may not correctly operate in any
of the following conditions:
• The lane is too narrow or wide.
• The system does not detect at least one
lane marking or when lanes merge or
split.
• Limited steering torque input is applied.
• Areas under construction or new
infrastructure.
• When modifications to the steering
system have been made.
• When using a spare tire.
Note:The driving assistance torque is limited
and may not be sufficient for all driving

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.

Detection issues can occur:
E71621
When driving on a different line
than the vehicle in front. AB With vehicles that edge into your
lane. The system can only detect
these vehicles once they move
fully into your lane.
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.
Optimal system performance requires a clear
view of the road by the windshield-mounted
camera.
Optimal performance may not occur if:
• The camera is blocked.
• There is poor visibility or lighting
conditions.
• There are bad weather conditions.
