1 second until Off is displayed.
WARNING
The laser sensor emits light when the igni-
tion is in mode II or higher, even if City
Safety™ has been switched off.
To switch City Safety™ on again:
•
Follow the same procedure as for switch-
ing City Safety™ off but select On by
pressing RESET.
or
•
Vehicles not equipped with keyless
drive: Press lightly on the remote key to
release it partially from the ignition slot.
Press the remote key into the ignition slot
again. Depress the brake pedal and press
the START/STOP ENGINE button to start
the engine. This restarts City Safety™
.
•
Vehicles equipped with the optional
keyless drive: Press the START/STOP

Depress the brake pedal and press the
START/STOP ENGINE button to start the
engine. This restarts City Safety™.
See page 79 for information on ignition modes.
City Safety™ will be automatically switched on
the next time the engine is started, even if it was
off when the engine was switched off.
Limitations
The sensor used by City Safety™ is designed
to detect cars and other larger motor vehicles
ahead of your vehicle in both daylight and dark-
ness.
However, there are certain limitations and the
laser sensor’s function may be reduced by, for
example, heavy rain or snowfall, or by dense
fog or thick, blowing dust or snow. Condensa-
tion, dirt, ice or snow on the windshield may
also interfere with the sensor’s function.
Objects such as warning flags hanging from
long objects on the roof or accessories such as
auxiliary lights or protective arches on the front
of the vehicle that are higher than the hood may
also impede the sensor’s function.
Braking distance to the vehicle ahead increa-
ses on slippery road surfaces, which may
reduce City Safety’s capacity to avoid a colli-
sion. In situations like this, the DSTC system
(see page 155) will help provide the best pos-
sible braking capacity and stability.
City Safety™ emits infrared light and measures
the way in which the light is reflected. There-
fore, vehicles or objects with low-reflective sur-
faces may not be detected. Normally, the
license plate and taillight reflectors give the
rear section of a vehicle ahead sufficient reflec-
tive surfaces to be detected.
NOTE
•
Keep the windshield in front of the laser
sensor free of ice, snow, dirt, etc. See
the illustration on page
167
•
Snow or ice on the hood deeper than
2 inches (5 cm) may obstruct the sen-
sor. Keep the hood free of ice and snow.
•
Do not mount or in any way attach any-
thing on the windshield that could
obstruct the laser sensor.
Troubleshooting
If Windshield sensors blocked appears in
the information display, this indicates that the
City Safety™ laser sensor is obstructed in
some way and cannot detect vehicles ahead of
you, which means that the system is not func-
tioning.
However, this message will not be displayed in
all situations in which the sensor is obstructed.
For this reason, the driver must ensure that the
area of the windshield in front of the sensor is
always kept clean.
