Get Lights and windshield wipers -> Exterior lighting Guide for Mercedes C Class 4 Door Second Generation (2007-2013)

Useful information

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.

Read the information on qualified

specialist workshops: (Y page 25).

Exterior lighting

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.

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

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 T, you turn on the

daytime running lamps and parking lamps.

If the engine is running and you turn the light

switch to L, 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 209).

If the engine is running and you turn the light

switch to T or L, the manual settings

take precedence over the daytime running

lamps.

Low-beam headlamps

WARNING

Active light function

Exterior lighting

113

Lights and windshield wipers

The active light function is a system that

moves the headlamps according to the

steering movements of the front wheels. In

this way, relevant areas remain illuminated

while driving. This allows you to recognize

pedestrians, cyclists and animals.

Active: when the lights are switched on.

Cornering light function

The cornering light function improves the

illumination of the road over a wide angle in

the direction you are turning, enabling better

visibility in tight bends, for example. The

cornering light function can only be activated

when the low-beam headlamps are switched

on.

Active:

if you are driving at speeds below

25mph (40 km/h) and switch on the turn

signal or turn the steering wheel.

if you are driving at speeds between

25 mph (40 km/h) and 45 mph (70 km/h)

and turn the steering wheel.

Not active: if you are driving at speeds above

25 mph (40 km/h) or switch off the turn

signals or turn the steering wheel to the

straight-ahead position.

The cornering light function may remain lit for

a short time, but is automatically switched off

after no more than three minutes.

Adaptive Highbeam Assist

WARNING

Adaptive Highbeam Assist does not recognize

road users:

who have no lights, e.g. pedestrians

who have poor lighting, e.g. cyclists

whose lighting is blocked, e.g. by a barrier

In very rare cases, Adaptive Highbeam Assist

may fail to recognize other road users that

have lights, or may recognize them too late.

In this or similarsituations, the automatic

high-beam headlamps will not be deactivated

or activated regardless. There is a risk of an

accident.

Always carefully observe the traffic conditions

and switch off the high-beam headlamps in

good time.

You can use this function to set the

headlamps to change betweenlow beam and

high beam automatically. The system

recognizes vehicles with their lights on, either

approaching from the opposite direction or

traveling in front of your vehicle, and

consequently switches the headlamps from

high beam to low beam.

The system automatically adapts the low-

beam headlamp range depending on the

distance to the other vehicle. Once the

system no longer detects any other vehicles,

it reactivates the high-beam headlamps.

The system's optical sensor is located behind

the windshield near the overhead control

panel.
