Important safety notes G
WARNING
When the EASY-ENTRY/EXIT feature adjusts
the steering wheel and the driver's seat, you
and other vehicle occupants – particularly
children – could become trapped. There is a
risk of injury.
While the EASY-ENTRY/EXIT feature is mak-

accident.
Always wait until the adjustment process is
complete before driving off. !
Do not activate the EASY-ENTRY/EXIT
feature, if the seat backrest is reclined too
far backwards. This can damage the front
or rear seats. You must first move the back- rest to a vertical position.

Adjusting the exterior mirrors G
WARNING
The exterior mirror on the front-passenger
side reduces the size of the image. Visible
objects are actually closer than they appear.
This means that you could misjudge the dis-
tance from road users traveling behind, e.g.
when changing lane. There is a risk of an acci-
dent.
For this reason, always make sure of the
actual distance from the road users traveling
behind by glancing over your shoulder. X
Make sure that the SmartKey is in position
1 or 2in the ignition lock (Y page 133).
X Press button :to select the left-hand

or
X Press button ;to select the right-hand
exterior mirror.
X Press button =up, down, or to the left or
right until you have adjusted the exterior
mirror to the correct position. You should
have a good overview of traffic conditions.
i The convex exterior mirrors provide a
larger field of vision.
i The exterior mirrors are heated automat-
ically if the rear window defroster is
switched on and the outside temperature is
low. Folding the exterior mirrors in/out elec-
trically X
Make sure that the SmartKey is in position
1 or 2in the ignition lock (Y page 133).
X Briefly press button :.
Both exterior mirrors fold in or out.
i Make sure that the exterior mirrors are
always folded out fully while driving. They
could otherwise vibrate.
i If you are driving faster than 9 mph
(15 km/ h), you can no longer fold in the
exterior mirrors.
Setting the exterior mirrors If the battery has been disconnected or com-
pletely discharged, the exterior mirrors must
be reset. The exterior mirrors will otherwise
not fold in when you select the "Fold in mir-
rors when locking" function in the on-board
computer (Y page 209).

Important safety notes
For reasons of safety, Mercedes-Benz recom- mends that you drive with the lights switched
on even during the daytime. In some coun-
tries, operation of the headlamps varies due
to legal requirements and self-imposed obli-
gations. 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 sym-
metrical 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 asym-
metrical low-beam headlamps at a qualified
specialist workshop as soon as possible after
crossing the border again. Light switch
Operation !
Switch off the parking lamps and low-
beam headlamps when you leave the vehi-
cle. This prevents the battery from dis-
charging.
! If the battery has been excessively dis-
charged, the parking lamps or standing
lamps are automatically switched off to
enable the next engine start. Always park
your vehicle safely and sufficiently lit
according to legal standards. Avoid the
continuous use of the Tparking lamps
for several hours. If possible, switch on the
X right or the Wleft standing lamp. 1

ahead position.
The cornering lamp may remain lit for a short
time, but is automatically switched off after
no more than three minutes. Headlamps and indicator lamps fog-
ged up on the inside
The headlamps and the indicator lamps in the exterior mirrors may fog up on the inside if
there is high atmospheric humidity.
X Drive with the headlamps switched on.
The level of moisture diminishes, depend-
ing on the length of the journey and the
weather conditions (humidity and temper-
ature).
If the level of moisture does not diminish:

gate/rear door is open when the engine is
running, particularly if the vehicle is moving,
exhaust fumes could enter the passenger
compartment. There is a risk of poisoning.
Turn off the engine before opening the tail-
gate/rear door. Never drive off with the tail-
gate/rear door open.

Important safety notes
G
DANGER
Xenon bulbs carry a high voltage. You can get an electric shock if you remove the cover of
the Xenon bulb and touch the electrical con-
tacts. There is a risk of fatal injury.
Never touch the parts or the electrical con-
tacts of the Xenon bulb. Always have work on
the Xenon bulbs carried out at a qualified spe-
cialist workshop. G
WARNING
Bulbs, lamps and connectors can get very hot when operating. If you change a bulb, you
could burn yourself on these components.
There is a risk of injury.
Allow these components to cool down before changing a bulb.
Do not use a bulb that has been dropped or if
its glass tube has been scratched.
The bulb may explode if:
R you touch it
R it is hot
R you drop it
R you scratch it
Only operate bulbs in enclosed lamps
designed for that purpose. Only install spare
bulbs of the same type and the specified volt- age.
Marks on the glass tube reduce the service
life of the bulbs. Do not touch the glass tube 108
