Cleaning the seat covers General notes
! Do not use microfiber cloths to clean gen-
uine leather, artificial leather or DINAMICA
covers. If used often, these can damage the cover.
i Note that regular care is essential to
ensure that the appearance and comfort of the covers is retained over time.
Genuine leather seat covers
! To retain the natural appearance of the
leather, observe the following cleaning
instructions:
R Clean genuine leather covers carefully
with a damp cloth and then wipe the cov- ers down with a dry cloth.
R Make sure that the leather does not
become soaked. It may otherwise
become rough and cracked.
R Only use leather care agents that have
been tested and approved by Mercedes-
Benz. You can obtain these from a quali- fied specialist workshop.
Leather is a natural product.
It exhibits natural surface characteristics, for
example:
R differences in the texture
R marks caused by growth and injury
R slight nuances of color
These are characteristics of leather and not
material defects. Seat covers of other materials
! Observe the following when cleaning:
R Clean artificial leather covers with a cloth
moistened with a solution containing 1% detergent (e.g. dish washing liquid).
R Clean cloth covers with a microfiber
cloth moistened with a solution contain-
ing 1% detergent (e.g. dish washing liq-
uid). Rub carefully and always wipe entire
seat sections to avoid leaving visible
lines. Leave the seat to dry afterwards.
Cleaning results depend on the type of
dirt and how long it has been there.
R Clean Alcantara® covers with a damp
cloth. Make sure that you wipe entire
seat sections to avoid leaving visible
lines.

Do not start the vehicle using a rapid charging device. If your vehicle's battery is discharged,
the engine can be jump-started from another vehicle or from a second battery using jumper
cables. Observe the following points:
R The battery is not accessible in all vehicles. If the other vehicle's battery is not accessible,
jump-start the vehicle using a second battery or a jump-starting device.
R You may only jump-start the vehicle when the engine and exhaust system are cold.
R Do not start the engine if the battery is frozen. Let the battery thaw first.
R Only jump-start from batteries with a 12 V voltage rating.
R Only use jumper cables which have a sufficient cross-section and insulated terminal clamps.
R If the battery is fully discharged, leave the battery that is being used to jump-start connected
for a few minutes before attempting to start. This charges the battery slightly.
R Make sure that the two vehicles do not touch.
Make sure that:
R the jumper cables are not damaged.
R when the jumper cables are connected to the battery, uninsulated sections of the terminal
clamp do not come into contact with other metal sections.
R the jumper cables cannot come into contact with parts which can move when the engine is
running, such as the V-belt pulley or the fan.
