2 Positive terminal (+)
3 Negative terminal (-)
X Lift up the cover of positive terminal 2on
your own vehicle.
X Connect positive terminal 2on your vehi-
cle to positive terminal of the donor battery
using the jump lead, beginning with your
own battery.
X Start the engine of the donor vehicle and
run it at idling speed.
X Connect negative terminal 3of the donor
battery to negative terminal of your vehi- cle's battery using the jump lead, connect-
ing the jump lead to the donor battery first.
X Start the engine.
X Electrical consumers can be switched on
again. Do not switch the lights on, however,
as this will overload the battery.
X Remove the jump lead from the negative
terminals 3first, and then from the posi-
tive terminals 2, each time disconnecting
from the battery on your own vehicle first.
X Have the battery checked at a qualified
specialist workshop, e.g. a Mercedes-Benz
Service Centre. Towing and tow-starting
Points to remember
G
Risk of accident
If you have the vehicle towed, you must use
a rigid towing bar if:
R the engine is not running.
R there is a brake system malfunction.
R there is a malfunction in the voltage sup-
ply or the vehicle's electrical system.
The electric power steering and the brake
force booster do not work when the engine
is not running. Greater braking force will
then be required and brake pedal travel will
be longer. If necessary, depress the brake
pedal with full force.
Do not tow the vehicle if the key cannot be
turned in the ignition lock. If this is the case,
the steering is locked and the vehicle can-
not be steered.
If you tow or tow-start another vehicle, its
weight must not exceed the maximum per-
missible gross vehicle weight of your vehi-
cle.
It is better to have the vehicle transported
than to have it towed. Practical advice

Notes on service products and capaci-
ties
Service products are:
R fuels (e.g. petrol, diesel)
R lubricants (e.g. engine oil, transmission oil,
grease)
R coolant
R brake fluid
Mercedes-Benz recommends that you only
use those products which have been tested
and specially approved by Mercedes-Benz for
your vehicle and are listed in the Mercedes-
Benz Specifications for Service Products
since:
R parts and service products are matched.
R damage caused by the use of non-approved
service products is not covered by the war-
ranty
You can obtain further information from any
Mercedes-Benz Service Centre. G
Risk of accident
When handling, storing and disposing of
any service products, please observe the
relevant regulations. Failure to do so could endanger other persons and the environ-
ment.
Keep service products away from children.
To protect your health, do not allow service
products to come into contact with your
eyes or open wounds. See a doctor imme-
diately if any service product is swallowed. H
Environmental note
Dispose of service products in an environ-
mentally-responsible manner. Fuels
G
Risk of explosion
Fuel is highly flammable. Fire, naked flames
and smoking are therefore prohibited when
handling fuels.
Before refuelling, turn off the engine and
the auxiliary heating*. G
Risk of injury
Do not allow fuel to come into contact with
skin or clothing.
Allowing fuels to come into direct contact
with your skin or inhaling fuel vapours is
damaging to your health. Tank capacity Total capacity Approximately 96 l

!
Do not use petrol to refuel vehicles with a
diesel engine. Do not use diesel to refuel
vehicles with a petrol engine. Never mix
diesel with petrol. Even small amounts of
the wrong fuel result in damage to the
injection system. Damage resulting from
adding the wrong fuel is not covered by the
warranty.
More information about refuelling and fuels
can be found in the "Operation" section. Technical data

Brake fluid
Over a period of time, the brake fluid absorbs
moisture from the air; this lowers its boiling
point. G
Risk of accident
If the boiling point of the brake fluid is too
low, vapour pockets may form in the brake
system when the brakes are applied hard
(e.g. when driving downhill). This would
impair braking efficiency.
Have the brake fluid renewed annually with
brake fluid that has been approved by Mercedes-Benz and have this confirmed in
the Service Booklet.
i There is usually a notice in the engine
compartment to remind you when the next
brake fluid change is due. Windscreen washer system
The washer fluid reservoir holds approxi-
mately 7.5 litres.
The headlamp cleaning system and the wind-
screen washer system are both supplied from
the washer fluid reservoir.
X At temperatures above freezing point:
top up the washer fluid reservoir with a
mixture of water and windscreen washer
concentrate (Y page 162).
X At temperatures below freezing point:
top up the washer fluid reservoir with a
mixture of water, antifreeze and wind-
screen washer concentrate (Y page 162). Technical data
