2008 MERCEDES-BENZ CLS COUPE brake

Jump-starting
292 G
Risk of injury
There is a risk of acid burns when jump-
starting a vehicle due to the gases which
escape from the battery. Do not lean over
the battery while the engine is being jump-
started. G
Risk of explosion
Gases escaping from the battery during
jump-starting may cause minor explosions.
Avoid creating sparks. Keep naked flames
away from the battery, and do not smoke.
Comply with safety precautions and take
protective measures when handling batter-
ies. You will find these under “Battery” in
the index.
X Make sure that the two vehicles do not
touch.
X Depress the parking brake.
X Move the selector lever to P.
X Switch off all electrical consumers.1 Positive terminal of your vehicle's battery
2 Positive terminal of donor battery
3 Negative terminal of donor battery
4 Connection for suitable earth point on the
vehicle
X Connect positive contact on your vehi-
cle 1 to positive terminal of the donor
battery 2 using the jump lead, connecting
the jump lead to your own battery first.
X Start the engine of the donor vehicle and
run it at idling speed.
X Connect the negative terminal of the donor
battery 3 and the earth contact on your
vehicle 4 using the jump lead, connecting
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 suitable
earthing point 4 and negative termi-
nal 3 first, then from the positive termi-
nals 1 and 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
293Towing and tow-starting
Points to remember
G
Risk of accident
If you tow the vehicle, you must use a rigid
towing bar if:
R the engine is not running
R there is a brake system malfunction
R the voltage supply or the vehicle's elec-
trical system is damaged
There
is no power assistance for the steer-
ing when the engine is not running. G
Risk of accident
The vehicle is braked when HOLD is activa-
ted.
Therefore, deactivate HOLD if the vehi-
cle is to be towed.
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.
When towing, observe the legal requirements
in all countries concerned. !
When towing, pull away slowly and with-
out

jerking. If the tractive power is too high,
the vehicles could be damaged. Do not use
the towing eye for recovery.
! You may tow the vehicle for a maximum
of 50 km. A towing speed of 50 km/h must
not be exceeded.
With towing distances over 50 km, the
entire vehicle needs to be lifted up and
transported.
! Only secure the tow cable or towing bar
to the towing eyes. You may otherwise
damage the vehicle.
R Vehicles with an automatic transmission
must not be tow-started.
R If the engine does not start, try jump-start-
ing it (Y page 291).
R If it is not possible to jump-start the vehicle,
have it towed to the nearest qualified spe-
cialist workshop, e.g. a Mercedes-Benz
Service Centre.
R If the vehicle has suffered transmission
damage, only tow it with the propeller shaft
disconnected.
R The selector lever must be in position N on
vehicles with automatic transmission. R
If you are towing the vehicle over a consid-
erable distance, this may only be done with
the rear axle raised.
R The ignition must be switched off if you are
towing the vehicle with the front/rear axle
raised. Intervention by ESP ®
could other-
wise damage the brake system.
R Before towing the vehicle, make sure that
the battery is connected and charged. Oth-
erwise:
-You cannot switch on the ignition
- You cannot move the selector lever to N
- You have no support when braking
i Switch off the automatic locking feature
before the vehicle is towed (Y page 127).
You could otherwise be locked out when
pushing or towing the vehicle. Practical advice

X Insert the wheel wrench handle into the
towing eye and tighten. Towing the vehicle
! You may tow the vehicle for a maximum
of 50 km. A towing speed of 50 km/h must
not be exceeded.
With towing distances over 50 km, the
entire vehicle needs to be lifted up and
transported.
! The engine must be switched off (key in
ignition lock in position 0 or position 1) if
the vehicle is being towed with the rear axle
raised or if the parking brake is being tested
on a dynamometer. Intervention by ESP ®
could otherwise damage the brake system.
X Turn the key to position 2 in the ignition

Service products and capacities
311Service products and capacities
Notes on service products and capaci-
ties
Service products are:
R fuels (e.g. petrol, diesel)
R lubricants
(e.g. engine oil, transmission oil)
R coolant
R brake fluid
R windscreen washer 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 Owner's Manual in the relevant chapter
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 recognise service products approved
by Mercedes-Benz by the following inscrip-
tion on the containers:
R MB-Freigabe (e.g. MB-Freigabe 229.51)
R MB Approval (e.g. MB Approval 229.51) Other designations or recommendations that
relate

to a level of quality or a specification in
accordance with an MB Approval have not
necessarily been approved by Mercedes-
Benz.
You can obtain further information from any
Mercedes-Benz Service Centre. G
Risk of injury
When handling, storing and disposing of
any service products, please observe the
relevant regulations, as you could other-
wise endanger yourself and others.
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.

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 every two
years with a 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 4.5 litres; on vehicles with the head-
lamp cleaning system* it holds 7 litres.
The headlamp cleaning system*
and the
windscreen washer system are both supplied
from the washer fluid reservoir.
