to maintain a 2-second interval will vary
according the speed of the vehicles.
WARNING
•
Adaptive Cruise Control is not a collision
avoidance system. The driver is always
responsible for applying the brakes if the
system does not detect another vehicle.
•
Adaptive Cruise Control does not react to
people or animals, or small vehicles such
as bicycles and motorcycles. It also does
not react to slow moving, parked or
approaching vehicles, or stationary
objects.
•
Do not use Adaptive Cruise Control in
demanding driving conditions such as city
driving or other heavy traffic situations, in
slippery conditions, when there is a great
deal of water or slush on the road, during
heavy rain or snow, in poor visibility, on
winding roads or on highway on- or off-
ramps.
The distance to the vehicle ahead (in the same
lane) is monitored by a radar sensor. Your vehi-
cle's speed is regulated by accelerating and
braking. The brakes may emit a sound when they
are being modulated by the adaptive cruise con-
trol system. This is normal.
WARNING
The brake pedal moves when the adaptive
cruise control system modulates the brakes.
Do not rest your foot under the brake pedal.
The ACC system is designed to smoothly regu-
late speed. However, the driver must apply the
brakes in situations that require immediate brak-
ing. This applies when there are great differences
in speed between vehicles, or if the vehicle ahead
brakes suddenly.
WARNING
Due to limitations in the radar sensor, braking
may occur unexpectedly or not at all, see
Adaptive Cruise Control – limitations (p. 186).
Adaptive Cruise Control can be put in active
mode at any permitted speed. However, if the
vehicle's speed falls below 18 mph (30 km/h) or
if engine speed (rpm) becomes too low, ACC dis-
engages (goes into standby mode) and will no
longer modulate the brakes. The driver will then
have to maintain a safe distance to the vehicle
ahead.
WARNING
When Adaptive Cruise Control is in standby
mode or is switched off completely, the
brakes will not be modulated automatically.
The driver must assume full control over the
vehicle.
Warning light—driver braking required
Adaptive Cruise Control can exert brake force
that is equivalent to approximately 40% of the
vehicle's total braking capacity. In situations
requiring more brake force than ACC can provide
and if the driver does not apply the brakes, an
audible signal from the Collision Warning system
will sound and warning light will illuminate (see
Collision warning* – function (p. 204)) in the
windshield to alert the driver to react.
NOTE
Strong sunlight, reflections, extreme light con-
trasts, the use of sunglasses, or if the driver is
not looking straight ahead may make the vis-
ual warning signal in the windshield difficult to
see.
