298 OperationVehicle careEngine cleaning
Prior to cleaning the engine compartment
make sure to protect electrical compo-
nents and connectors from the intrusion of
water and cleaning agents.
Corrosion protection, such as MB Anticor-
rosion Wax should be applied to the engine
compartment after every engine cleaning.
Before applying, all control linkage bush-
ings and joints should be lubricated. The
poly-V-belt and all pulleys should be pro-
tected from any wax.
Vehicle washing
Do not use hot water or wash your vehicle
in direct sunlight. Only use a mild car wash
detergent, such as Mercedes-Benz ap-
proved Car Shampoo.
Thoroughly spray the vehicle with a dif-
fused jet of water. Direct only a very weak
spray towards the ventilation intake. Use
plenty of water and rinse the sponge and
chamois frequently. Rinse with clear water and thoroughly dry
with a chamois. Do not allow cleaning
agents to dry on the finish.
Due to the width of the vehicle, fold in ex-
terior rear view mirrors prior to running the
vehicle through an automatic car wash to
prevent damage to the mirrors.
In the winter, thoroughly remove all traces
of road salt as soon as possible.
When washing the underbody, do not for-
get to clean the inner sides of the wheels.Ornamental moldings
For regular cleaning and care of very dirty
chrome-plated parts, use a chrome clean-
er.
Headlamps, tail lamps, side markers,
turn signal lenses
Use a mild car wash detergent, such as
Mercedes-Benz approved Car Sham-
poo, with plenty of water.
To prevent scratches, never apply strong
force and use only a soft, non-scratchy
cloth when cleaning the lenses. Do not at-
tempt to wipe dirty lenses with a dry cloth
or sponge.
iVehicles with KEYLESS-GO*:
If a door handle is hit by a strong jet of
water, and a SmartKey with
KEYLESS-GO* is in close proximity, i.e.
within approx. 3 ft. (approx. 1 m), the
vehicle could be inadvertently locked
or unlocked.

312 Practical hintsWhat to do if …?Messages in the display
The control system shows warning and
malfunction messages in the multifunction
display.
Certain warning and malfunction messag-
es are accompanied by an audible signal.
Address these messages accordingly and
follow the additional instructions given in
this Operator’s Manual.
Selecting the malfunction memory menu in
the control system (
page 134) displays
both cleared and uncleared messages.
High-priority messages appear in the mul-
tifunction display in red color.
Certain messages of high priority cannot
be cleared from the multifunction display
using the reset button (page 22).
Other messages of high priority and mes-
sages of less immediate priority can be
cleared from the multifunction display us-
ing the reset button (
page 22). These are
then stored in the malfunction message
memory (
page 150).On the pages that follow, you will find a
compilation of the most important warning
and malfunction messages that may ap-
pear in the display. High priority messages
appear on a red background.
Warning!
G
All categories of messages contain impor-
tant information which should be taken note
of and, where a malfunction is indicated, ad-
dressed as soon as possible at an autho-
rized Mercedes-Benz Center.
Failure to repair condition noted may cause
damage not covered by the Mercedes-Benz
Limited Warranty, or result in property dam-
age or personal injury.Warning!

iTurning the SmartKey in the starter
switch to position2, or pressing the
KEYLESS-GO* start/stop button twice
causes all lamps as well as the multi-
function display to come on. Make sure
that they are all in working order before
starting your journey.

Safe vehicle operation depends on proper
exterior lighting and signaling. It is there-
fore essential that all bulbs and lamp as-
semblies are in good working order at all
times.
Correct headlamp adjustment is extremely
important. Have headlamps checked and
readjusted at regular intervals and when a
bulb has been replaced. See an authorized
Mercedes-Benz Center for headlamp ad-
justment.

Only use 12 volt bulbs of the same type
and with the specified watt rating.
Switch lights off before changing a bulb
to prevent short circuits.
Always use a clean lint-free cloth when
handling bulbs.
Your hands should be dry and free of oil
and grease.
If the newly installed bulb does not
come on, visit an authorized
Mercedes-Benz Center.
Have the LEDs and bulbs for the follow-
ing lamps replaced by an authorized

Warning!
G
Keep bulbs out of reach of children.
Bulbs and bulb sockets can be very hot. Al-
low the lamp to cool down before changing
a bulb.
Halogen lamps contain pressurized gas. A
bulb can explode if you:
touch or move it when hot
drop the bulb
scratch the bulb
Wear eye and hand protection.
Because of high voltage in Bi-Xenon lamps,
it is dangerous to replace the bulb or repair
the lamp and its components. We recom-
mend that you have such work done by a
qualified technician.
