Introduction
The
control system is activated as soon as the
starter switch is in position 1.
The control system enables you to call up
information about your vehicle and to change
vehicle settings.
For example, you can use the control system
to find out when your vehicle is next due for
maintenance service, to set the language for
messages in the instrument cluster display,
and much more. G
Warning!
A driver’s attention to the road and traffic
conditions must always be his/her primary
focus when driving.
For your safety and the safety of others,
selecting features through the multifunction
steering wheel should only be done by the
driver
when traffic and road conditions permit
it to be done safely. Control system

Warning!
When operating the climate control, the air
that enters the passenger compartment
through the air vents can be very hot or very
cold
(depending on the set temperature). This
may cause burns or frostbite to unprotected
skin in the immediate area of the air vents.
Always keep sufficient distance between
unprotected parts of the body and the air
vents. If necessary, use the air distribution
adjustment to direct the air to air vents in the
vehicle interior that are not in the immediate
area of unprotected skin.
For best possible performance of the climate
control:
X Keep the air intake grille in front of the
windshield
free of snow, leaves, sticks, and
any other debris.
X Always keep all air vents and grilles in the
passenger compartment free from
obstruction.

Coolant level
The engine coolant is a mixture of water and
anticorrosion/antifreeze.
When checking the coolant level, the vehicle
must be parked on level ground, and the
coolant temperature must be below 158‡
(70†). G
Warning!
In order to avoid any potentially serious burns:
R Use extreme caution when opening the
hood if there are any signs of steam or
coolant leaking from the cooling system, or
if the coolant temperature display indicates
that the coolant is overheated.
R Do not remove the cap on the coolant
expansion tank if the coolant temperature
is above 158‡ (70†). Allow the engine to
cool down before removing the cap. The
coolant expansion tank contains hot fluid
and is under pressure.
R Using a rag, slowly open the cap
approximately 1
/ 2 turn counterclockwise
to relieve excess pressure. If opened
immediately, scalding hot fluid and steam
will be blown out under pressure.
R Do not spill antifreeze on hot engine parts.
Antifreeze contains ethylene glycol which
may burn if it comes into contact with hot
engine parts. Example illustration: SLK 350
X
Using a rag, slowly open cap ;
approximately 1
/ 2 turn counterclockwise
to relieve excess pressure.
X Continue turning cap ; counterclockwise

X Add coolant as required.
X Screw cap ; back on and tighten it.

“Technical data” section ( Y page 301) and
(Y page 304). Washer system and headlamp

G
Warning!
Washer solvent/antifreeze is highly
flammable. Do not spill washer solvent/
antifreeze on hot engine parts, because it may
ignite and burn. You could be seriously
burned.
! Always use washer solvent/antifreeze
where temperatures may fall below
freezing point. Failure to do so could result
in damage to the washer system/fluid
reservoir. 196
