Vehicle occupants could be struck in the
event of sudden braking or an accident, for
instance, if you:
R transport other heavy or sharp-edged
objects in the skibag
R do not secure the skibag with the lashing
straps
There is a risk of accident and injury.
Store only skis in the skibag. Always secure
the skibag with the lashing straps so that it

Important safety notes G
WARNING
If the rear bench seat/rear seat and seat
backrest are not engaged they could fold for- wards, e.g. when braking suddenly or in the
event of an accident.
R The vehicle occupant would thereby be
pushed into the seat belt by the rear bench
seat/rear seat or by the seat backrest. The
seat belt cannot protect as intended and
could result in additional injury.
R Objects or loads in the boot/luggage com-
partment cannot be restrained by the seat
backrest.
This poses an increased risk of injury.
Before every trip, make sure that the seat
backrests and the rear bench seat/rear seat
are engaged before every trip.
! When folding the rear seat backrest for-
wards, ensure that there are no items lying on the seat cushions. These items could other-
wise be damaged or could themselves dam-
age the rear seats.
Observe the loading guidelines (Y page 305).
The outer and the centre rear seat backrests can be folded down separately to increase the lug-
gage compartment capacity. The division ratio is
40/20/40. 308

Lashing eyelets Observe the following notes on securing loads:
R Observe the loading guidelines (Y page 305).
R Secure the load using the lashing eyelets.
R Distribute the load on the lashing eyelets
evenly.
R Do not use elastic straps or nets to secure a
load. These are intended only as anti-slip pro-
tection for light loads.
R Do not route lashing materials across sharp
edges or corners.
R Pad sharp edges for protection. 310

Wipe the wood trim and trim elements with a
damp, lint-free cloth, e.g. a microfibre cloth.
X Trim elements with piano black finish:
wipe with a soft, damp cotton cloth. Use clean
water.
X Heavy soiling: use care and cleaning prod-
ucts recommended and approved by
Mercedes-Benz.
Cleaning the seat covers General notes
! Do not use a microfibre cloth to clean covers
made out of real leather, artificial leather or
DINAMICA. If used frequently, this can dam-
age the cover.
Note that regular care is essential to make sure
that the appearance and comfort of the covers
are 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 covers
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 qualified
specialist workshop.
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 sec-
tions 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 DINAMICA covers with a damp cloth.
Make sure that you wipe entire seat sec-
tions 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 solution.
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 cleaning
agents recommended and approved by
Mercedes-Benz. Care

R
It is particularly important to observe the described order when connecting and disconnecting
the jump leads.
R Never connect or disconnect the battery terminals while the engine is running. G
WARNING
A discharged battery can freeze at temperatures below freezing point. When jump-starting the
vehicle or charging the battery, gases can escape from the battery. There is a risk of an explosion.
Allow the frozen battery to thaw out before charging it or jump-starting.
If the warning and indicator lamps do not light up on the instrument cluster when temperatures are low, it is probably because the discharged battery has frozen. In this case, you may neither jump-
start the vehicle nor charge the battery. The service life of a battery that has been thawed may be
reduced. The starting characteristics may be impaired, especially at low temperatures. Have the
thawed battery checked at a qualified specialist workshop.
All vehicles:
! Vehicles with a petrol engine:
avoid repeated and lengthy starting attempts. Otherwise, the
non-combusted fuel may damage the catalytic converter.
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 Vehicles with a petrol engine: jump-start the vehicle only when the engine and exhaust system
are cold.
R All vehicles except vehicles with a lithium-ion battery: do not start the engine if the battery
is frozen. Let the battery thaw first.
R Jump-starting may be performed only using batteries with a nominal voltage of 12 V.
R Use only jump leads that 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 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 that 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 that the ignition is switched off . All indicator lamps on the instrument cluster must be
off. When using the key, turn the key to position 0in the ignition lock and remove it (Y page 144).
X Switch off all electrical consumers, e.g. rear window heating, lighting etc.
