WARNING
When Adaptive Cruise Control is in
standby mode or is switched off com-
pletely, 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 situa-
tions requiring more brake force than ACC
can provide and if the driver does not apply
the brakes, an audible signal from the Colli-
sion Warning system will sound and warning
light will illuminate (see Collision warning* –
function (p. 199)) in the windshield to alert
the driver to react.
NOTE
Strong sunlight, reflections, extreme light
contrasts, the use of sunglasses, or if the
driver is not looking straight ahead may
make the visual warning signal in the wind-
shield difficult to see.

WARNING
Adaptive Cruise Control only warns of
vehicles detected by the radar sensor, see
Adaptive Cruise Control – limitations
(p. 181). In some cases there may be no
warning or the warning may be delayed.
The driver should always apply the brakes
when necessary.
Steep inclines and/or heavy loads
ACC is primarily intended for use on fairly
level roads. The system may have difficulty
maintaining the correct distance to a vehicle
ahead on steep inclines, if the vehicle is car-
rying a heavy load or is towing a trailer. In
these situations, the driver should always be
prepared to apply the brakes if necessary.
