Light
s 73Lights
Light switch
For reasons of safety, Mercedes-Benz recom-
mends that you drive with the lights switched
on even during the daytime. In some coun -
tries, daytime use of headlamps varies due to
legal requirements and self-imposed obliga -
tions. In these countries, dipped-beam head -
lamps are switched on when the ignition is
switched on.
i If you drive in countries in which traffic
drives on the opposite side of the road to
the country where the vehicle is registered ,
oncoming traffic may be dazzled by the
asymmetrical dipped-beam headlamps.
Have the headlamps changed to symmet-
rical dipped beam when driving in these
countries. You can obtain information
about this from any Mercedes-Benz Servic e
Centre. $

Risk of accident
Do not keep any objects in the driver's foot-
well. If you use a floormat or carpet in the
driver's footwell, make sure that they are
correctly secured and that there is suffi-
cient clearance for the pedals.
Objects could otherwise get between the
pedals in the event of sudden braking or
acceleration. You may then no longer be
able to brake, change gear or accelerate as
intended. This may result in an accident and
injury . G
Risk of poisoning
Never leave the engine running in enclose d
spaces. The exhaust gases contain carbon
monoxide. Inhaling exhaust fumes consti-
tutes a health hazard and could lead to loss
of consciousness or even death.
! Do not depress the accelerator pedal
when starting the engine.
i If you depress the brake when starting the
engine, pedal travel will be unusually long
and there will be less pedal resistance. Controls

Notes on changing bulbs
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sur e
that all bulbs function correctly at all times . G
Risk of injury
Bulbs and lamps can be very hot. Yo u
should therefore allow them to cool down
before you change them. Otherwise, you
could be burned if you touch them.
Keep bulbs out of the reach of children.
Otherwise, they could damage them, for
example, and injure themselves.
Never use a bulb which has been dropped.
Such a bulb may explode and injure you.
H7 bulbs are pressurised and could explode
when you change them, particularly if they
are very hot. You should therefore wear eye
protection and gloves when you are chang-
ing them. G
Risk of injury
Xenon bulbs carry a high voltage. You could
get an electric shock and be seriously or
even fatally injured if you touch the electri c
contacts on xenon bulbs. Therefore, neve r
remove the cover from xenon bulbs . Do not change xenon bulbs yourself, bu
t
have them replaced at a qualified specialist
workshop which has the necessary special-
ist knowledge and tools to carry out the
work required.
Mercedes-Benz recommends that you use
a Mercedes-Benz Service Centre for this
purpose. In particular, work relevant to
safety or on safety-related systems must be
carried out at a qualified specialist work-
shop. Practical advice
