WARNING!
should remain vigilant on the road and keep their
hands on the steering wheel at all times.
● Always keep the sensor clean. Carefully wipe the
sensor lens with a soft cloth. Do not use solvents or
abrasive substances.
these warnings can result in a collision and death or
serious personal injury.
Display Warnings And Maintenance
● Do not remove any screws from the sensor. Doing
so could cause an ACC system malfunction or failure
and require a sensor realignment.
“FRONT RADAR SENSOR TEMPORARILY
BLOCKED” WARNING
Speed Reductions On Bends
The Adaptive Cruise Control system has the capability
to make slight speed reductions during bends to
enhance vehicle stability and passenger comfort. This
feature can be especially helpful in roundabouts
or on gently curved roads where the curvature
gradually increases. However, it cannot compensate for
abrupt steering maneuvers or moderate-to-high lateral
accelerations in general.
● If the sensor or front end of the vehicle is damaged
due to a collision, see an authorized dealer for
service.
The “ACC Front Radar Sensor Temporarily Blocked”
warning will display and a chime will sound when
conditions temporarily limit system performance.
● Do not attach or install any accessories near
the sensor, including transparent material or
aftermarket grilles. Doing so could cause an ACC
system failure or malfunction.
This most often occurs at times of poor visibility, such
as in snow or heavy rain. The ACC system may also
become temporarily blinded due to obstructions, such
as mud, dirt or ice. In these cases, the instrument
cluster display will read “ACC/FCW Unavailable Wipe
Front Radar Sensor” and the system will deactivate.
When the condition that deactivated the system is no
longer present, the system will return to the “Adaptive
Cruise Control Off” state and will resume function by
simply reactivating it.
In scenarios where the traffic situation demands it,
it is the drivers responsibility to apply the brakes,
as needed, to further decrease the vehicle's speed,
ensuring stability on tight bends or steep descents.
The “ACC Front Radar Sensor Temporarily Blocked”
message can sometimes be displayed while driving in
highly reflective areas (i.e. ice and snow, or tunnels
with reflective tiles). The ACC system will recover after
the vehicle has left these areas. Under rare conditions,
when the radar is not tracking any vehicles or objects in
its path this warning may temporarily occur.
NOTE:
Extension Of Adaptive Cruise Control: Co-
Driver
● If the “ACC Front Radar Sensor Temporarily Blocked”
message occurs frequently (e.g. more than once on
every trip) without any snow, rain, mud, or other
obstruction, have the radar sensor realigned at an
authorized dealer.
The Adaptive Cruise Control system can operate in
coordination with the Co-Driver system

to provide "Autonomous Level 2 Assistance." The Co-
Driver is capable of maintaining a consistent speed and
distance, adaptable to the vehicles ahead, and keeping
the car centered within the lane.
If the “ACC Front Radar Sensor Temporarily Blocked”
warning is active, Fixed Speed Cruise Control is still
available.
● Installing a snow plow, front-end protector, an
aftermarket grille or modifying the grille is not
recommended. Doing so may block the sensor and
inhibit ACC/Full Brake Control System operation.
If weather conditions are not a factor, the driver should
examine the sensor. It may require cleaning or removal
of an obstruction. The sensor is located in the center of
the vehicle behind the lower grille.
NOTE:
This system is designed to assist the driver, who should
always remain fully attentive while driving. The ultimate
responsibility lies with the driver, who must consider
the traffic conditions to ensure safe driving. The driver
“CLEAN FRONT WINDSHIELD” WARNING
