General notes
Some systems carry out a self-diagnosis when the ignition is switched on. Several warning and indicator lamps can thereby temporarily light up or flash. This behaviour is non-critical. These
warning and indicator lamps only indicate a malfunction if they light up or flash after the engine is started or during a journey. Safety

Leather is a natural product.
It has natural surface properties, e.g.:
R unevenness in structure
R marks caused by growth and injury
R subtle colour differences
These are characteristics of leather and not
material faults.
Seat covers from other materials
! Observe the following when cleaning:
R clean artificial leather covers with a cloth
moistened with a solution containing 1%
detergent (e.g. washing-up liquid).
R clean cloth covers with a microfibre cloth
moistened with a solution containing 1%
detergent (e.g. washing-up liquid). Rub
carefully, and always wipe entire seat
sections to avoid leaving visible lines.
Leave the seat to dry afterwards. Clean-
ing results depend on the type of dirt and how long it has been there.
R Clean DINAMICA covers with a damp
cloth. Make sure that you wipe entire
seat sections to avoid leaving visible
lines.
Cleaning the seat belts G
WARNING
Seat belts may be severely weakened if
bleached or coloured. This may lead to the
seat belts, for example, tearing or failing in an accident. There is an increased risk of injury,
possibly even fatal.
Never bleach or colour seat belts.
! Do not clean the seat belts using chemical
cleaning agents. Do not dry the seat belts at
temperatures above 80 † or in direct sun-
light.
X Use clean, lukewarm water and soap solu-
tion. Cleaning the roof lining and carpets X
Roof lining: if it is very dirty, use a soft
brush or dry shampoo.
X Carpets: use the carpet and textile clean-
ing agents recommended and approved by
Mercedes-Benz. Care

Do not use a rapid charging device to start the vehicle. If your vehicle's battery is discharged,
the engine can be jump-started from another vehicle or from a second battery using jump
leads. 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 Keep away from fire and open flames.
R Do not start the engine if the battery is frozen. Let the battery thaw first.
R All vehicles except Mercedes-AMG vehicles: do not start the engine if the battery is
frozen. Let the battery thaw first.
R Jump-starting may only be performed using batteries with a nominal voltage of 12 V.
R Only use jump leads that have a sufficient cross-section and insulated terminal clamps.
R Do not lean over the battery.
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 empty battery a little.
R Make sure that the two vehicles do not touch.
Make sure that:
R The jump leads are not damaged.
R Non-insulated parts of the terminal clamps do not come into contact with other metal parts
while the jump leads are connected to the battery.
R The jump leads cannot come into contact with parts which can move when the engine is
running, such as the V-belt pulley or the fan.
X Secure the vehicle by applying the electric parking brake.
X Shift the transmission to position P.
X Make sure the ignition is switched off (Y page 161). All indicator lamps in the instrument
cluster must be off. When using the key, turn the key to position 0in the ignition lock and
remove it (Y page 161).
X Switch off all electrical consumers, e.g. rear window heating, lighting etc.
