driver is always responsible for main-
taining a safe distance to the vehicle
ahead.
Function
Location of the laser sensor in the windshield
City Safety™ monitors traffic ahead of you
using a laser sensor mounted in the upper sec-
tion of the windshield. If a collision is imminent,
City Safety™ will automatically apply the
brakes at approximately 50% of the vehicle’s
full braking effect if you are traveling at speeds
between 2-18 mph (4-30 km/h).
•If the difference in speed between your
vehicle and the vehicle ahead is less than
approximately 9 mph (15 km/h), CitySafety™ can help prevent a collision from
taking place.
•If the difference in speed is between
approximately 10-18 mph (16-30 km/h),
City Safety™ alone cannot avoid a colli-
sion. The driver must apply the brakes for
full braking effect.
When the function activates and applies the
brakes, a message will appear in the informa-
tion display to indicate that the system is/has
been active.
NOTE
•When City Safety™ applies the brakes,
the brake lights will illuminate.
•In cases where City Safety™ has stop-
ped the vehicle, the system will then
release the brakes. The driver must
apply the brakes to keep the vehicle at
a standstill.
Using City Safety™
NOTE
The City Safety™ function is activated auto-
matically each time the engine has been
switched off and restarted.
On and OffIn certain situations, it may be desirable to
switch City Safety™ off, such as when driving
in close quarters where leaves, branches, etc.
may obscure the hood and windshield.
When the engine is running, City Safety™ can
be switched off as follows:
Press My Car in the center console control
panel and go to Settings
Car settings
Driver support systemsCity safety.
Select
Off.
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
ENGINE button to switch off the engine.
Depress the brake pedal and press the
START/STOP ENGINE button to start the
engine. This restarts City Safety™.
See page 81 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 138) 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
page 157.
•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 Windscreen 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.
The following table shows some of the situa-
tions that can cause the message to be dis-
played and suggested actions.

Turn the handle located under the left side
of the dash approximately 20-25 degrees
clockwise to release the hood lock.
Lift the hood slightly. Press the release
control (located under the right front edge
of the hood) to the left, and lift the hood
WARNING
Check that the hood locks properly when
closed.

WARNING
The cooling fan may start or continue to
operate (for up to 6 minutes) after the engine
has been switched off.
WARNING
The ignition should always be completely
switched off before performing any opera-
tions in the engine compartment.
The distributor ignition system operates at
very high voltages. Special safety precau-
tions must be followed to prevent injury.
Always turn the ignition off when:
•Replacing distributor ignition compo-
nents e.g. plugs, coil, etc.
•Do not touch any part of the distributor
ignition system while the engine is run-
ning. This may result in unintended
movements and body injury.
