Collision warning
Warning light in the windshield
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 City Safety
system will sound and warning light will illuminate
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
warning symbol in the windshield difficult to
see.
WARNING
Adaptive Cruise Control only warns of vehicles
detected by the radar sensor. In some cases
there may be no warning or the warning may
be delayed. The driver should always apply the
brakes when necessary.
Head-up-display*
A flashing light alerts the driver
A flashing icon will appear in the head-up display
to alert the driver of a collision risk.
NOTE
Strong sunlight, reflections, extreme light con-
trasts, the use of sunglasses, or if the driver is
not looking straight ahead may make the
warning symbol in the windshield difficult to
see.
