370 OperationVehicle careCleaning the panorama roof with power
tilt/sliding panel
The rear part of the tilt/sliding panel has a
protective layer on the inside.
Use a soft, clean cloth and a mild win-
dow cleaning solution.
An automotive glass cleaner is recom-
mended.Light alloy wheels
If possible, clean wheels once a week.
Use Mercedes-Benz approved Wheel
Care, a soft bristle brush and a strong
spray of water for cleaning the light al-
loy wheels.
Plastic and rubber parts
Use a gentle dishwashing detergent or
mild detergent for delicate fabrics as a
washing solution.
Instrument cluster and cup holders
Use a gentle dishwashing detergent or
mild detergent for delicate fabrics as a
washing solution.
Wipe with a cloth moistened in a luke-
warm solution.
!Do not use a dry cloth, abrasives, sol-
vents or cleaners containing solvents.
Do not touch the protective layer with
hard objects such as an ice scraper or
ring. Never apply strong force and only
use a soft, non-scratching cloth when
cleaning the rear part of the tilt/sliding
panel.
Otherwise you may scratch or damage
the protective layer.
!Only use acid-free cleaning materials.
Acid may cause corrosion or damage
the clear coat.!The vehicle should not be parked for an
extended period of time immediately
after it has been cleaned, especially not
after the wheel rims have been cleaned
with wheel rim cleaner. Wheel rim
cleaners can lead to increased corro-
sion of the brake disks and brake pads.
Therefore, the vehicle’s brake system
should always be warmed-up before it
is parked after cleaning. To do so,
please drive your vehicle for several
minutes to allow the brakes to dry.
When applying Mercedes-Benz ap-
proved Tire Care and Mercedes-Benz
approved Wheel Care products, take
care not to spray them on the brake
disks. !Do not use oil or wax on these parts.!To prevent scratches, do not use scour-
ing agents.

Replacing bulbs
Notes on bulb replacement
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 light
up, visit an authorized Mercedes-Benz
Center.Have the LEDs and bulbs for the following
lamps replaced by an authorized
Mercedes-Benz Center:
Additional turn signals in the exterior
rear view mirrors
High mounted brake lamp
Bi-Xenon* lamps
Front fog lamps
Rear lamps (except license plate
lamps)
Front side marker lamps
Warning!
G
Bulbs and bulb sockets can be very hot. Al-
low the lamp to cool down before changing
a bulb.
Keep bulbs out of reach of children.
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.
iHave the headlamp adjustment
checked regularly.
