79Hazard warning lamps
The hazard warning lamps still operate if the
ignition is switched off. They switch on auto-
matically if an airbag is deployed or if you
brake sharply and bring the vehicle to a halt
from a speed of more than 70 km/h.
X To switch on: press button1.
All turn signals flash. If you now switch on
a turn signal using the combination switch
(Y page 78), only the turn signal lamp on
the corresponding side of the vehicle will
flash.
X To switch off: press button1. Adjusting the headlamp range (halo-
gen headlamps)
The headlamp range control allows you to
adjust the cone of light from the headlamps
to suit the vehicle load.
You can only adjust the headlamp range while
the engine is running. Position Load

Risk of fire
Washer fluid concentrate is highly flamma-
ble. Fire, naked flames and smoking are
prohibited when washer fluid concentrate
is being handled.
X At temperatures above freezing:
fill the washer fluid reservoir with a mix of
water and windscreen washer concentrate
(Y page 175).
X At temperatures below freezing:
fill the washer fluid reservoir with a mix of
water, antifreeze additive and windscreen
washer concentrate ( Ypage 175). Adapt
the mixing ratio to the outside tempera-
tures.
X Mix the windscreen washer fluid in a con-
tainer beforehand.
! Only use windscreen washer fluid which
is suitable for plastic lamp lenses. Unsuit-
able windscreen washer fluid could dam-
age the plastic lamp lenses of the head-
lamps.
X To open: pull cap1upwards by the tab.
X To close: press cap 1onto the filler neck
until it clicks into place. Tyres and wheels
Points to remember
! For safety reasons, Mercedes-Benz rec-
ommends that you only use tyres and
wheels which have been approved by
Mercedes-Benz specifically for your vehi-
cle. These tyres have been specially adap-
ted for use with the control systems, such
as ABS or ESP ®
, and are marked as follows:
R MO = Mercedes-Benz Original
R MOE = Mercedes-Benz Original Extended
(with run-flat characteristics)*
*Mercedes-Benz Original Extended tyres
should only be used on wheels that have
been specifically approved by Mercedes-
Benz.
If you use other tyres and wheels,
Mercedes-Benz cannot accept any respon-
sibility for damage that may result from
this. Further information about tyres,
wheels and approved combinations can be
obtained from any Mercedes-Benz Service
Centre.
If you use tyres other than those tested and
recommended for Mercedes-Benz vehi-
cles, characteristics such as handling, vehi-
cle noise emissions and fuel consumption may be adversely affected. In addition, the
wheels may come into contact with the
body or axle components when heavily loa-
ded or when driving with snow chains. This
could result in damage to the tyres or the
vehicle.
! Retreaded tyres are neither tested nor
recommended by Mercedes-Benz, since
previous damage cannot always be detec-
ted on retreaded tyres. As a result,
Mercedes-Benz cannot guarantee vehicle
safety if retreaded tyres are fitted. Do not
fit used tyres if you have no information
about their previous usage. G
Risk of accident
If wheels or tyres other than those which
have been tested are fitted:
R the brakes or chassis components could
be damaged.
R wheel and tyre clearances can no longer
be guaranteed.
This could cause an accident.
Modification work on the brake system and
wheels is not permitted, nor is the use of
spacer plates or brake dust shields. This inva- Operation

R Do not work with wet or greasy fingers.
R If the new bulb still does not light up, con-
sult a qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre.
i Due to the location of the bulbs in the
front headlamps, it is best to have these
changed at a qualified specialist workshop,
e.g. a Mercedes-Benz Service Centre.
i Have the headlamp setting checked reg-
ularly at a qualified specialist workshop,
e.g. a Mercedes-Benz Service Centre. Changing the front bulbs

Notes on service products and capaci-
ties
Service products are:
R fuels (e.g. petrol, diesel)
R lubricants (e.g. engine oil, transmission oil)
R coolant
R brake fluid
R windscreen washer fluid
Mercedes-Benz recommends that you only
use those products which have been tested
and specially approved by Mercedes-Benz for
your vehicle and are listed in the Mercedes-
Benz Owner's Manual in the relevant chapter
since:
R parts and service products are matched
R damage caused by the use of non-approved
service products is not covered by the war-
ranty
You can recognise service products approved
by Mercedes-Benz by the following inscrip-
tion on the containers:
R MB-Freigabe (e.g. MB-Freigabe 229.51)
R MB Approval (e.g. MB Approval 229.51) Other designations or recommendations that
relate to a level of quality or a specification in
accordance with an MB Approval have not
necessarily been approved by Mercedes-
Benz.
You can obtain further information from any
Mercedes-Benz Service Centre. G
Risk of injury
When handling, storing and disposing of
any service products, please observe the
relevant regulations, as, otherwise, you
could endanger yourself and others.
Keep service products away from children.
To protect your health, do not allow service
products to come into contact with your
eyes or open wounds. See a doctor imme-
diately if any service product is swallowed. H
Environmental note
Dispose of service products in an environ-
mentally-responsible manner. Fuels
G
Risk of explosion
Fuel is highly flammable. Fire, naked flames
and smoking are therefore prohibited when
handling fuels.
Switch off the engine before refuelling. G
Risk of injury
Do not allow fuel to come into contact with
skin or clothing.
Allowing fuels to come into direct contact
with your skin or inhaling fuel vapours is
damaging to your health.

Brake fluid
Over a period of time, the brake fluid absorbs
moisture from the air; this lowers its boiling
point. G
Risk of accident
If the boiling point of the brake fluid is too
low, vapour pockets may form in the brake
system when the brakes are applied hard
(e.g. when driving downhill). This would
impair braking efficiency.
Have the brake fluid renewed every two
years with a brake fluid that has been
approved by Mercedes-Benz and have this
confirmed in the Service Booklet. i
There is usually a notice in the engine
compartment to remind you when the next
brake fluid change is due. Windscreen washer system
G
Risk of fire
Windscreen washer concentrate is highly
flammable. Fire, naked flames and smoking
are prohibited when windscreen washer
concentrate is being handled.
The washer fluid reservoir holds approxi-
mately 6.4 litres.
The headlamp cleaning system* and the
windscreen washer system are both supplied
from the washer fluid reservoir. Further information on windshield washer
fluid and the mixing ratio can be found on
(Y
