Changing the bulbs
271Changing the bulbs
Notes on changing bulbs
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure
that all bulbs function correctly at all times. G
Risk of injury
Bulbs and lamps can be very hot. You
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 electric
contacts on xenon bulbs. Therefore, never
remove the cover from xenon bulbs. Do not change xenon bulbs yourself, but
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.
G
Risk of injury
HiP bulbs are pressurised and may explode
when you change them, thereby injuring
you.
Do not change HiP bulbs yourself; 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. !
Do not change the LEDs yourself. You
could otherwise damage the LEDs or parts
of the vehicle. OverviewPractical advice

The wiper arms could start moving and
cause an injury if you leave the windscreen
wipers switched on.
Remove the key from the ignition lock
before replacing the wiper blades.

Risk of injury
The jack is designed only to raise the vehi-
cle for a short time while a wheel is being
changed.
If you intend to work under the vehicle, it
must be placed on stands.
Make

sure that the jack is placed on a firm,
non-slip, level surface. Do not use wooden
blocks or similar as jacking supports. Oth-
erwise, the jack will not be able to achieve
its load-bearing capacity due to the restric-
ted height. Practical advice

Flat tyre
277Do not start the engine at any time while
the wheel is being changed.
Do not lie under the vehicle when it is being
supported by the jack. If you do not raise
the vehicle as described, it could slip off the
jack (e.g. if the engine is started or a door
or the boot lid are opened or closed) and
you could be seriously injured.
Using the TIREFIT kit
You can use the TIREFIT kit to seal small
punctures, particularly those in the tyre tread.
You can use TIREFIT in outdoor temperatures
down to -20 °C. G
Risk of accident
In the following situations, your safety is at
particular risk and TIREFIT is unable to pro-
vide breakdown assistance:
R if there are cuts or punctures in the tyre
greater than 4 mm
R if the wheel rim is damaged
R if you have driven at very low tyre pres-
sures or on a flat tyre
Do not drive any further. Consult a qualified
specialist workshop which has the neces- sary specialist 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.
X Do not remove any foreign objects which
have penetrated the tyre, e.g. screws or
nails.
X Remove TIREFIT, the accompanying "max.
80 km/h" sticker and the electric air pump
from the stowage well underneath the boot
floor ( Y page 217).1
Driver's field of vision sticker
2 Wheel sticker X
Affix part 1 of the sticker within the driv-
er's field of vision.
X Affix part 2 of the sticker near the valve
on the wheel with the defective tyre.
G Risk of injury
TIREFIT must not come into contact with
your skin, eyes or clothing.
R If TIREFIT comes into contact with your
eyes or skin, immediately rinse thor-
oughly with clean water.
R Change out of clothing which has come
into contact with TIREFIT immediately.
R If an allergic reaction occurs, consult a
doctor immediately.
Keep TIREFIT away from children.
R If TIREFIT is swallowed, immediately
rinse your mouth out thoroughly with
water and drink plenty of water.
R Do not induce vomiting. Consult a doctor
immediately.
