WARNING
PRE-SAFE ®
Brake does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R when cornering
As a result, PRE-SAFE ®
Brake may neither
give warnings nor intervene in all critical
situations .There is a risk of an accident.
Always pay careful attention to the traffic
situation and be ready to brake.
In order to maintain an appropriate distance
from the vehicle in front and thus prevent a
collision, you must apply the brakes yourself.
X To activate/deactivate: activate or
deactivate PRE-SAFE ®
Brake in the on-
board computer (Y page 225).
When PRE-SAFE ®
Brake is activated, the
0001 symbol appears in the multifunction
display as long as the HOLD function is
deactivated (Y page 179).
On vehicles with Parking Guidance, the
0001 symbol is displayed when position P
is engaged or you are driving faster than
22 mph (35 km/h).
Following damage to the front end of the
vehicle, have the configuration and operation
of the radar sensors checked at a qualified
specialist workshop. This also applies to
collisions at low speeds where there is no
visible damage to the front of the vehicle. Theft deterrent locking system

Useful information
i This Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are
possible. Please note that your vehicle may
not be equipped with all features
described. This also applies to safety-
related systems and functions.

General notes
For reasons of safety, Mercedes-Benz
recommends that you drive with the lights
switched on even during the daytime. In some
countries, operation of the headlamps varies
due to legal requirements and self-imposed
obligations. Notes on driving abroad
Conversion to symmetrical low beam Switch the headlamps to symmetrical low
beam in countries in which traffic drives on
the opposite side of the road from the country
where the vehicle is registered. This prevents
glare to oncoming traffic. When using
symmetrical lights, the edge of the road is not
lit as widely and as far ahead as normal.
Have the headlamps converted at a qualified
specialist workshop as close to the border as
possible before driving in these countries.
Conversion to asymmetrical low beam
after returning Have the headlamps converted back to
asymmetrical low-beam headlamps at a
qualified specialist workshop as soon as
possible after crossing the border again. Setting the exterior lighting

Automatic headlamp mode
G
WARNING
When the ligh tswitch is set to 0004, the low-
beam headlamps may not be switched on
automatically if there is fog, snow or other
causes of poor visibility due to the weather
conditions such as spray. There is a risk of an
accident.
In such situations, tur nthe light switch to
000C.
The automatic headlamp feature is only an
aid. The driver is responsible for the vehicle's
lighting at all times.
0004 is the favored light switch setting. The
light setting is automatically selected
according to the brightness of the ambient
light (exception: poor visibility due to weather
conditions such as fog, snow or spray):
R SmartKey in position 1in the ignition lock:
the parking lamps are switched on or off
automatically depending on the brightness
of the ambient light.
R With the engine running: if you have
activated the daytime running lamps
function via the on-board computer, the
daytime running lamps or the low-beam
headlamps and parking lamps are switched
on or off automatically depending on the
brightness of the ambient light.
X To switch on automatic headlamp
mode: turn the light switch to 0004.
Only for Canada:
The daytime running lamps improve the
visibility of your vehicle during the day. The
daytime running lamps function is required by
law in Canada. It cannot therefore be
deactivated.
When the engine is running and the vehicle is
stationary: if you move the selector lever from
a drive position to P, the daytime running
lamps/low-beam headlamps go out after
three minutes.
When the engine is running, the vehicle is
stationary and in high ambient light: if you turn the light switch to
0016, you turn on the
daytime running lamps and parking lamps.
If the engine is running and you turn the light
switch to 000C, the manual settings take
precedence over the daytime running lamps.
USA only:
The daytime running lamps improve the
visibility of your vehicle during the day. To do
this, the daytime running lamps function must
be switched on using the on-board computer
(Y page 227).
If the engine is running and you turn the light
switch to 0016or000C, the manual settings
take precedence over the daytime running
lamps.
Low-beam headlamps G
WARNING
When the light switch is set to 0004, the low-
beam headlamps may not be switched on
automatically if there is fog, snow or other
causes of poor visibility due to the weather
conditions such as spray. There is a risk of an
accident.
In such situations, turn the light switch to
000C.
Even if the light sensor does not detect that
it is dark, the parking lamps and low-beam
headlamps switch on when the ignition is
switched on and the light switch is set to the
000C position. This is a particularly useful
function in the event of rain and fog.
X To switch on the low-beam headlamps:
turn the SmartKey in the ignition lock to
position 2or start the engine.
X Turn the light switch to 000C.
The green 000Cindicator lamp in the

In conditions where visibility is poor due to
fog, snow or rain, the fog lamps improve
visibility as well as making it easier for other
road users to see you. They can be operated
