Store brake fluid only in the original closed
container and keep it out of the reach of
children. Comply with safety regulations
when handling brake fluid.
! Brake fluid corrodes paint, plastic and
rubber .Ifpaint, plastic or rubbe rhas come
into contact with brake fluid, rinse with
wate rimmediately. G
WARNING
The brake fluid constantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake
fluid is too low, vapo rpockets may form in the
brake system when the brakes are applied
hard. This would impair braking efficiency.
There is a risk of an accident.
You should have the brake fluid renewed at
the specified intervals.
! If the brake fluid level in the brake fluid
reservoir has fallen to the MIN mark or
below, check the brake system
immediately for leaks. Also check the
thickness of the brake linings. Visit a
qualified specialist workshop immediately.
Do not add brake fluid. This does not
correct the malfunction.
Have the brake fluid renewed every two
years.
Observe the information on brake fluid in the
"Technical data" section ( Ypage 245). Check the brake fluid level regularly, e.g.
weekly or when refueling. Checking the brake fluid level
X
Stop your vehicle as far away from traffic
as possible on level ground.
X Switch off the engine.
X Secure the vehicle to prevent it from rolling
away.
X Open the hood (Y page 240).
X Check the brake fluid level.
The brake fluid level is correc tifthe level is
between the MIN mark and MAX mark on
brake fluid reservoir 0005.
X Close the hood. Washer fluid
G
WARNING
Windshield washer concentrate is highly
flammable. If it comes into contact with hot
engine components or the exhaust system it
could ignite. There is a risk of fire and injury.
Make sure that no windshield washer
concentrate is spilled next to the filler neck.
! Only use washer fluid that is suitable for
plastic lamp lenses, e.g. MB SummerFit or
MB WinterFit. Unsuitable washer fluid
could damage the plastic lenses of the
headlamps. Example: washer fluid reservoir
Add windshield washer concentrate to the
washer fluid all year round. Observe the
information on washer fluid in the "Technical
data" section (Y
page 326).246

Draining the fuel filter G
WARNING
Fuel is highly flammable. Improper handing of
fuel creates a risk of fire and explosion.
Avoid fire, open flames ,smoking and creating
sparks under all circumstances. Switch off the
ignitio nand auxiliary heating before carrying
ou tw ork to the fuel system. Always wear
protective gloves. H
Environmental note
Dispose of the water-fuel mixture in an
environmentally responsible manner.
! When the 000Eindicator lamp lights up,
drain the fuel filter with water separator
immediately. Otherwise, the engine may be
damaged. If the
000E indicator lamp in the instrument
cluster goes on, drain the fuel filter with water
separator 0026immediately.
i We recommend that you have this
maintenance work carried out at a qualified
specialist workshop.
X Park the vehicle safely and secure it from
rolling away.
X Switch off the auxiliary heating system .
X Switch off the engine.
X Open the hood (Y page 240).
X Place a suitable receptacle under drain
hose 0005.
X Turn the key to position 2in the ignition
lock.
X Open drain plug 0006immediately until the
water/fuel mixture flows out of drain
hose 0005.
X Screw in drain plug 0006as soon as
approximately 0.2 US qt (0.2 l) of the
water/fuel mixture have been collected.
i The electrical fuel pump halts the flow of
the water/fuel mixture after 30 seconds.
X After draining, turn the key back to
position 0in the ignition lock.
X Dispose of the collected water/fuel
mixture in an environmentally responsible
manner, e.g. at a qualified specialist
workshop.
X Check drain plug 0006.The drain plug must
be closed.
When the engine is running and drain
hose 0006is open, fuel is lost through drain
hose 0005.
X Close the hood.
If the 000E indicator lamp does not go out
after draining:
X Drain the fuel filter again.
X If the 000E indicator lamp does not go out
after draining for the second time, have the
cause checked immediately at a qualified
specialist workshop. Engine compartment

WARNING
During charging and jump-starting, explosive
gases can escape from the battery. There is a
risk of an explosion.
Particularly avoid fire, open flames, creating
sparks and smoking. Ensure there is sufficient
ventilation while charging and jump-starting.
Do not lean over a battery. G
WARNING
Battery acid is caustic. There is a risk of injury.
Avoid contact with the skin, eyes or clothing.
Do not inhale any battery gases. Do not lean
over the battery. Keep children away from
batteries. Wash battery acid immediately with
water and seek medical attention.
! Only charge the installed battery with a
battery charger that has been tested and
approved by the distributor named on the
inside of the front cover. This device allows
the battery to be charged when it is
installed in the vehicle. The vehicle's
electronics may otherwise be damaged. 254

water and seek medical attention. G
WARNING
Non-combusted fuel can collect in the
exhaust system and ignite. There is a risk of
fire. Avoid repeated and lengthy starting
attempts.
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 donor battery
using jumper cables. For this purpose, the
vehicle has a jump-starting connection point
in the engine compartment.
The additional battery in the engine
compartmenti s not suitable for jump-starting
operations. If your vehicle requires jump-
starting, or if you use it to jump-start another
vehicle, use the jump-starting connection
point in the engine compartment.
When jump-starting, 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
donor battery or a jump-starting device.
R Do not start the engine if the battery is
frozen. Let the battery thaw first.
R Jump-starting may only be performed from
batteries with a nominal voltage of 12 V.
R Only use jumper cables that have a
sufficient cross-section and insulated
terminal clamps.
R If the battery is fully discharged, attach the
battery of another vehicle 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 jumper cables are not damaged.
R bare parts of the terminal clamps do not
come into contact with other metal parts
while the jumper cables are connected to
the battery.
R the jumper cables cannot come into
contact with parts such as the V-belt pulley
or the fan. These parts move when the
engine is started and while it is running.
i Jumper cables and further information
regarding jump starting can be obtained at
any qualified specialist workshop. Before connecting the jumper cables
On vehicles with a battery main switch, check
whether the battery main switch is switched
on (Y page 132).
X Apply the parking brake.
X Move the selector lever of the automatic
transmission to position P.
X Switch off all electrical consumers, e.g.
