2009 MERCEDES-BENZ CL COUPE run flat

X
Remove the cap from valve Eon the faulty
tyre. X
Make sure pressure release screw Fon
pressure gauge Gis fully closed.
X Screw filler hose Donto valve E.
X Insert plug Ainto the socket of the ciga-
rette lighter* (Y page 282) or into a 12 V
power socket in your vehicle (Y page 282).
X Turn the key to position 2(Y page 182) in
the ignition lock.
X Press on/off switch ?on the electric air
pump to I.
The electric air pump is switched on. The
tyre is inflated.
i First, TIREFIT is pumped into the tyre. The
pressure can briefly rise to around 5 bar.
Do not switch off the electric pump dur-
ing this phase.
X Let the electric pump run for five minutes.
The tyre should then have a pressure of at
least 1.8 bar. !
Do not operate the electric air pump for
longer than eight minutes at a time without
a break. It may otherwise overheat.
The air pump can be operated again once
it has cooled down.
If a pressure of 1.8 bar is not reached
after five minutes:
X Switch off and disconnect the electric air
pump and drive the vehicle forwards or
backwards approximately 10 m.
This distributes the TIREFIT more evenly.
X Pump up the tyre again. G
Risk of accident
If a pressure of 1.8 bar is not achieved after
five minutes, the tyre is too badly damaged.
Do not drive any further. Consult a qualified
specialist workshop which has the necessary
specialist knowledge and tools to carry out
the work required. Mercedes-Benz recom-
mends that you use a Mercedes-Benz Service
Centre for this purpose. In particular, work
relevant to safety or on safety-related sys-
tems must be carried out at a qualified spe-
cialist workshop.
When a tyre pressure of at least 1.8 bar
is reached:
X Press on/off switch ?on the electric air
pump to 0.
The electric air pump is switched off.
X Remove the TIREFIT kit from the wheel.
! After use, excess TIREFIT may run out of
the filler hose. This may cause stains.
Therefore, place the filler hose in the plastic
bag in which the TIREFIT kit was contained.
X Stow away the TIREFIT kit, the electric air
pump and the warning triangle.
X Pull away immediately.
X Stop after driving for approximately ten
minutes and check the tyre pressure with
the electric air pump. Flat tyre

Place the "Minispare" emergency spare
wheel* or the spare wheel onto the cen-
tring pin and push it on. X
Tighten the wheel bolts until they are fin-
ger-tight.
X Unscrew the centring pin.
X Tighten the last wheel bolt until it is finger-
tight.
Lowering the vehicle X
Lower the vehicle. To do this, turn the crank
of the jack anti-clockwise until the vehicle
is standing firmly on the ground again.
X Place the jack to one side. X
Tighten the wheel bolts evenly in a cross-
wise pattern in the sequence indica-
ted (: toA). The tightening torque is
150 Nm. G
Risk of accident
Have the tightening torque checked immedi-
ately after a wheel is changed. The wheels
could work loose if they are not tightened to
a torque of 150 Nm.
X Turn the jack back to its initial position and
store it and the rest of the vehicle tool kit
in the stowage well under the boot floor.
i When you are driving with the "Minispare"
emergency spare wheel* fitted, the tyre
pressure loss warning system cannot func-
tion reliably. MOExtended run-flat system*
The MOExtended run-flat system may only be
used in conjunction with the tyre pressure
loss warning system or with the tyre pressure
monitor.
! The maximum permissible distance which
can be driven in run-flat mode depends on
the load in the vehicle. It is 50 km if the
vehicle is partially laden and 30 km if fully
laden.
The maximum range that can be driven in
emergency operation is measured from the
point at which the pressure loss warning Flat tyre

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

R MOE = Mercedes-Benz Original Exten-

If you use other tyres, Mercedes-Benz can-
not accept any responsibility for damage
which may occur. Information about tyres
can be obtained from any Mercedes-Benz
Service Centre.
! If you fit tyres other than those tested and
recommended by Mercedes-Benz, charac-
teristics such as handling, noise levels and
fuel consumption, etc. may be adversely
affected. In addition, when driving with a
load, tyre dimensional variations could
cause the tyres to come into contact with
the bodywork and axle components. This
could result in damage to the tyres or the
vehicle.
i Further information about tyres and
wheels can be obtained from any
Mercedes-Benz Service Centre.
i You will find a table of tyre pressures on
the inside of your vehicle's fuel filler flap. You will find further information about tyre
pressures in the “Operation” section
(Y
page 298).
i Notes on vehicle tyres:
Always
R fit tyres of the same size on a given axle
(left/right)
R fit the same type of tyres on your vehicle
at a given time (summer tyres, winter
tyres, MOExtended tyres)
i Vehicles with the MOExtended run-flat
system are not equipped with the TIREFIT
kit. 43
Therefore, it is recommended that you
additionally equip your vehicle with the
TIREFIT kit* when fitting tyres that do not
feature run-flat properties, e.g. winter
tyres.
i A TIREFIT kit is available from any quali-
fied specialist workshop, e.g. a Mercedes-
Benz Service Centre. Tyres of the same dimensions
