2009 MERCEDES-BENZ CL COUPE Owners Manual

message appears in the multi-function dis-
play.
You must not exceed a maximum speed of
80 km/h. G
Risk of accident
The handling characteristics of your vehicle
deteriorate in run-flat mode, for example:
R when cornering
R when braking
R when accelerating rapidly
Adapt your driving style accordingly and avoid
sudden changes in direction and sudden
acceleration, as well as driving over obstacles
(i.e. kerbs, potholes), and driving off-road.
This is particularly the case when the vehicle
is heavily laden.
The maximum permissible distance that can
be driven in run-flat mode depends to a large
extent on the loads placed on the vehicle. It
can be shorter due to high speeds, a heavy
load, sudden acceleration and/or manoeu-
vring, the road surface condition, outside tem-
perature, etc., or further, if you drive carefully
and conservatively.
Do not continue to drive in run-flat mode if:
R you hear banging noises.
R the vehicle starts to shake.
R you see smoke and smell rubber.
R ESP ®
is intervening constantly.
R there are tears in the sidewalls of the tyre.
After driving in run-flat mode, you must have
the wheel(s) checked for damage at a quali-
fied specialist workshop which has the nec-
essary specialist knowledge and tools to carry
out the work required. The faulty tyre must be
replaced in every case.
Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety or
on safety-related systems must be carried out
at a qualified specialist workshop. i
On a vehicle with MOExtended tyres, only
use MOExtended spare tyres. These must
be of the size specified for the vehicle. Battery
Notes on the vehicle battery
In order for the battery to achieve the maxi-
mum possible service life, it must always be
sufficiently charged.
Have the battery charge checked more fre-
quently if you use the vehicle mainly for short
trips or if you leave it standing idle for a
lengthy period.
To prevent damage from corrosion, only
replace the battery with one that has a central
ventilation cover.
Consult a Mercedes-Benz Service Centre if
you wish to leave your vehicle parked up for
a long period of time. G
Risk of injury
Comply with safety precautions and take pro-
tective measures when handling batteries. Risk of explosion
Fire, naked flames and
smoking are prohibited
when handling the battery.
Avoid creating sparks.
Battery acid is caustic.
Avoid contact with the skin,
eyes or clothing.
Wear suitable protective
clothing, in particular
gloves, an apron and a face
mask.
Immediately rinse acid
splashes off with clean
water. Consult a doctor if
necessary. 382

Wear eye protection.
Keep children away.
Observe this Owner's Man-
ual.
H
Environmental note
Do not dispose of batteries in the household
rubbish. Dispose of defective batteries in an
environmentally responsible manner. Take
them to a Mercedes-Benz Service Centre or
to a special collection point for old batteries. G
Risk of injury
For safety reasons, Mercedes-Benz recom-
mends that you only use batteries which have
been tested and approved for your vehicle by
Mercedes-Benz. These batteries provide
increased impact protection to prevent vehi-
cle occupants from suffering acid burns
should the battery be damaged in the event
of an accident.
To prevent acid burns, observe the following
safety notes when handling batteries:
R do not lean over the battery.
R do not place any metal objects on a battery.
You could otherwise cause a short circuit
and the battery's gas mixture could ignite.
R make sure that you do not create an elec-
trostatic charge, e.g. by wearing synthetic
clothing or as a result of friction on fabrics.
Therefore, you should not pull or slide the
battery over carpets or other synthetic
materials. R
never touch the battery first. To discharge
a possible electrostatic charge, step out of
the vehicle first and touch the bodywork.
R do not wipe the battery using a cloth. The
battery may explode as a result of electro-
static charge or due to flying sparks.
! Before loosening the terminal clamps of
the battery, switch off the engine and
remove the key or, on vehicles with KEY-
LESS GO*, make sure that the ignition is
not switched on. In the instrument cluster,
all of the indicator lamps must be out. Oth-
erwise, you may destroy electronic compo-
nents, such as the alternator.
i Mercedes-Benz recommends that you
have work involving the battery, e.g.
removal, charging and replacement, car-
ried out at a qualified specialist workshop,
e.g. a Mercedes-Benz Service Centre.
Installation location of the battery Your vehicle is equipped with a battery in the
engine compartment. It is located on the front
bulkhead under the filter box on the right-
hand side of the vehicle when viewed in the
direction of travel.

ers. The vehicle will then use very little
energy, thus conserving the battery.
i If the battery is discharged, you must use
the emergency key element to unlock the
vehicle. Charging the battery
G
Risk of injury
Only charge the installed battery using a
Mercedes-Benz approved battery charger.
Otherwise, the vehicle's electronic system
may be damaged. Only charge the battery in
a well-ventilated area. As the battery is being
charged, gases can escape and generate
minor explosions. This could injure you and
other persons or cause damage to the paint-
work or acid corrosion on the vehicle.
You can obtain information about battery
chargers which allow the battery to be
charged while still installed from a qualified
specialist workshop, e.g. a Mercedes-Benz
Service Centre. G
Risk of injury
There is a risk of acid burns during the charg-
ing process due to the gases which escape
from the battery. Do not lean over the battery
during the charging process.

If your vehicle's battery is discharged, the
engine can be jump-started from another
vehicle or from an external battery using jump
leads.
Observe the following points:
R jump-starting may only be performed when
the engine and catalytic converter are cold.
R do not start the engine if the battery is fro-
zen. Let the battery thaw first.
R jump-starting may only be performed from
batteries with a nominal voltage of 12 V.
R only use jump leads which have a sufficient
cross-section and insulated terminal
clamps.
i Jump leads and further information about
jump-starting can be obtained from any
Mercedes-Benz Service Centre.
! Avoid repeated and lengthy starting
attempts.
Never start the vehicle using a rapid battery
charger. G
Risk of injury
There is a risk of acid burns when jump-start-
ing a vehicle due to the gases which escape
from the battery. Do not lean over the battery
while the engine is being jump-started. 384

If you tow or tow-start another vehicle, its
weight must not exceed the maximum per-
missible gross vehicle weight of your vehicle. G
Risk of accident
The vehicle is braked when Hold or Distronic
Plus* is activated. Therefore, deactivate
HOLD and Distronic Plus if the vehicle is to be
towed.
It is better to have the vehicle transported
than to have it towed.
When towing, observe the legal requirements
in all countries concerned.
! Make sure that the electric parking brake
is released. If the electric parking brake is
faulty, consult a qualified specialist work-
shop. Mercedes-Benz recommends that
you use a Mercedes-Benz Service Centre.
! 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,
as this could damage the vehicle. If in
doubt, recover the vehicle with a crane.
! You may tow the vehicle for a maximum
of 50 km. A towing speed of 50 km/h must
not be exceeded.
For towing distances over 50 km, the entire
vehicle must be lifted up and transported.

key instead of the Start/Stop button. Turn
the key to position 2in the ignition lock and
set the automatic transmission to N. Then
turn the key back to 0and leave it in the
ignition lock.
! Only secure the tow cable or towing bar
to the towing eyes. You could otherwise
damage the vehicle. R
Tow-starting the vehicle is not permitted.
R Vehicles with 4MATIC* must not be towed
with the front or rear axle raised.
R If the engine does not start, try jump-start-
ing it (Y page 384).
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 automatic transmission DIRECT
SELECT lever must be in the Nposition
when towing the vehicle.
R The ignition must be switched off if you are
towing the vehicle with the front/rear axle
raised. Otherwise, intervention by ESP ®
could damage the brake system.

Fuses
Notes on changing fuses
The fuses in your vehicle serve to close down
faulty circuits. If a fuse blows, all the compo-
nents on the circuit and their functions will
fail.
Blown fuses must be replaced with fuses of
the same rating, which you can recognise by
the colour and value. The fuse ratings are lis-
ted in the fuse allocation chart. A Mercedes-
Benz Service Centre will be happy to advise
you. G
Risk of fire
Only use fuses that have been approved for
Mercedes-Benz vehicles and which have the
required fuse rating for the systems con-
cerned. Do not attempt to repair or bridge
faulty fuses. A circuit overload could other-
wise cause a fire. Have the cause traced and
rectified at a qualified specialist workshop,
e.g. a Mercedes-Benz Service Centre.
If the newly inserted fuse also blows, have the
cause traced and rectified at a qualified spe-
cialist workshop, e.g. a Mercedes-Benz
Service Centre.
! Only use fuses that have been approved
for Mercedes-Benz vehicles and which
have the correct fuse rating for the system
concerned. Otherwise, components or sys-
tems could be damaged.
! Turn off the internal on-board electrical
system of the vehicle if you are carrying out
work on the fuses. Further information can
be found in the index under "Disconnecting
the battery".
The fuses are located in various fuse boxes:
R fuse boxes on the right-hand and left-hand
sides of the dashboard
R fuse box in the engine compartment on the
left-hand side of the vehicle R
fuse box in the engine compartment on the
right-hand side of the vehicle
R fuse box in the rear
