intervenes:
X Do not deactivate ESP ®
under any circum-
stances.
X When pulling away, only depres sthe accel-
erator pedalasf ar as is necessary.
X Adapt yourd riving style to suitt he prevail-
ing road and weather conditions.
i Only use wheels with the recommended
tyre sizes. Only then will ESP ®
function
properly.
ETS/4ETS (Electronic Traction System) Traction control is part of ESP
®
.
Traction control brakes the drive wheels indi-
vidually if they spin. This enables you to pull
away and accelerate on slippery surfaces, for
example if the road surface is slippery on one
side. On vehicles with 4MATIC, more drive
torque is also transferred to the wheel or
wheels with traction.
Traction control remains active if you deacti-
vate ESP ®
.

MOExtended tyres (tyres with run-flat
characteristics) G
WARNING
When driving in emergency mode, the driving
characteristics deteriorate, e.g. when corner-
ing, accelerating quickly and when braking.
There is arisk of accident.
Do not exceed the stated maximu mspeed.
Avoid abrupt steering and driving manoeu-
vres, and driving over obstacles (kerbs ,pot-
holes, off-road). This applies in particular to a
laden vehicle.
Stop driving in emergency mode if:
R you hear banging noises.
R the vehicle start stoshake.
R you see smok eand smell rubber.
R ESP ®
is intervening constantly.
R ther eare tears in the sidewalls of the tyre.
After driving in emergency mode, have the
wheel rims checked at aqualified specialist
workshop with regard to their further use. The
faulty tyre must be replaced.
With MOExtended tyres (tyres with run-flat
characteristics), you can continue to drive
your vehicle even if ther eisatotal loss of
pressure in one or more tyres.
MOExtended tyres may only be used in con-
junction with an activ etyre pressure loss
warning system or with an activ etyre pres-
sure monitor.
The maximum driving distance is approx-
imately 80 km when the vehicle is partially
laden, and approximately 30 km when the
vehicle is fully laden.
In addition to the vehicle load, the driving dis-
tanc epossible depends upon:
R speed
R road condition
R outside temperature
The driving distanc epossible in run-flat mode
may be reduced by extreme driving condi-
tions/manoeuvres, or it can be increased
through amoderat estyle of driving. The maximum permissible distanc
ewhich
can be driven in run-flat mode is counted from
the momen tthe tyre pressure loss warning
appears in the multifunction display.
You must not exceed amaximum speed of
80 km/h.
i When replacing one or all tyres, make
sure that you only use tyres marked
"MOExtended". Make sure that you only
use the size of tyre specified for the vehicle. TIREFIT kit
Using the TIREFIT kit TIREFIT is
atyre sealant.
You can use TIREFIT to seal punctures of up
to 4m m, particularly those in the tyre tread.
You can use TIREFIT at outside temperatures
down to Ò20 †. G
WARNING
In the following situations, the tyre sealant is
unable to provide sufficient breakdown assis-
tance, as it is unable to seal the tyre properly:
R there are cuts or punctures in the tyre
larger than those mentioned above.
R the wheel rim is damaged.
R you have driven at very low tyre pressures
or on aflat tyre.
There is arisk of accident.
Do not drive any further. Contact aqualified
specialist workshop. G
WARNING
The tyre sealant is harmful and causes irrita-
tion. It must not come into contact with your
skin, eyes or clothing or be swallowed. Do not
inhale TIREFIT fumes. Keep tyre sealant away
from children. There is arisk of injury. Flat tyre

WARNING
If wheels and tyres of the wrong size are used,
the wheel brakes or suspension components
may be damaged. There is arisk of accident.
Always replac ewheels and tyre swith those
that fulfil the specifications of the original part
(designation ,manufacturer, model). G
WARNING
Af lat tyre severely impairs the driving, steer-
ing and braking characteristics of the vehicle.
There is arisk of accident.
Tyres without run-flat characteristics:
R do not drive with aflat tyre.
R immediately replac ethe flat tyre with your
emergenc yspare wheel or spare wheel, or
consult aqualified specialist workshop.
Tyres with run-flat characteristics:
R pay attention to the information and warn-
ing notices on MOExtended tyre s(tyres
with run-flat characteristics).
Accessories that are not approved for your
vehicle by Mercedes-Ben zorare not being
usedc orrectly can impair the operating
safety. Before purchasing and using non-approved
accessories, visit aqualified specialist work-
shop and enquire about:
R suitability
R lega lstipulations
R factory recommendations
Information on the dimensions and types of
wheels and tyres for yourv ehicle can be
found under "Wheel/tyre combinations"
(Y page 341).
Information on air pressure for the tyres on
your vehicle can be found:
R on the tyre pressure label on the fuel filler
flap (Y page 157)
R under "Tyre pressure" (Y page 331)
R in the "Tyre pressure" section
Modification work on the brake system and
wheels is not permitted. The use of wheel
spacers or brake dust shields is not permit-
ted. This invalidates the general operating
permit for the vehicle.
i Further information on wheels and tyres
can be obtained at any qualified specialist
workshop. Operation
Information on driving
Check the tyre pressures when the vehicle is
heavily laden and, if necessary, adjust.
While driving, pay attention to vibrations,
noises and unusual handling characteristics,
e.g. pulling to one side. This may indicat ethat
the wheels or tyres are damaged. If you sus-
pect that atyre is defective, reduce your
speed immediately. Stop the vehicle as soon
as possible to chec kthe wheels and tyres for
damage. Hidden tyre damage could also be
causing the unusual handling characteristics.
If you find no signs of damage, have the tyres
and wheels checked at aqualified specialist
workshop.
When parking your vehicle, make sure that
the tyres do not get deformed by the kerb or 328
OperationWheels and tyres

other obstacles. If it is necessary to drive over
kerbs, speed humps or similar elevations, try
to do so slowly and at an obtuse angle. Oth-
erwise, the tyres, particularly the sidewalls,
may be damaged. Regular checking of wheels and tyres
G
WARNING
Damaged tyres can cause tyre inflation pres-
sure loss. As aresult, you could lose control
of your vehicle. There is arisk of accident.
Check the tyres regularly for signs of damage
and replace any damaged tyres immediately.
Regularly check the wheels and tyres of your
vehicle for damage at least once amonth, as
well as after driving off-road or on rough
roads. Damaged wheels can cause aloss of
tyre pressure. Pay particular attention to
damage such as:
R cuts in the tyres
R punctures
R tears in the tyres
R bulges on tyres
R deformation or severe corrosion on wheels
Regularly check the tyre tread depth and the
condition of the tread across the whole width
of the tyre (Y page 329). If necessary, turn
the front wheels to full lock in order to inspect
the inner side of the tyre surface.
All wheels must have avalve cap to protect
the valve against dirt and moisture. Do not fit
anything ontot he valve other than the stand-
ard valve cap or other valve caps approved by
Mercedes-Benz for your vehicle. Do not fit any
other valve caps or systems, e.g. tyre pres-
sure monitoring systems.
Regularly check the pressure of all the tyres,
particularly prior to long trips. Adjust the tyre
pressure as necessary (Y page 331).
Observe the notes on the emergenc yspare
wheel (Y page 351). The service life of tyres depends on various
factors, including the following:
R
driving style
R tyre pressure
R tyre mileage Tyret

WARNING
Insufficient tyre tread will reduce tyre trac-
tion. The tyre is no longer able to dissipate
water. This means that on wet road surfaces,
the risk of aquaplaning increases, in particular
where speed is not adapted to suit the driving
conditions. There is arisk of accident.
If the tyre pressure is too high or too low, tyres
may exhibit different levels of wear at differ-
ent locations on the tyre tread. Thus, you
should regularly check the tread depth and
the condition of the tread across the entire
width of all tyres.
Minimum tyre tread depth for:
R summer tyres: 3mm
R M+S tyres: 4mm
For safety reasons, replace the tyres before
the legally prescribed limit for the minimum
tyre tread depth is reached.. Selecting, fitting and replacing tyres
R Only fit tyres and wheels of the same type
and make.
R Only fit tyres of the correc tsize ontot he
wheels.
R Run in new tyres at moderate speeds for
the first 100 km. They only reach their full
performanc eafter this distance.
R Do not drive with tyres which have too little
tread depth. This otherwise significantly
reduces the traction on wet roads (aqua-
planing).
R Replace the tyres after six years at the lat-
est, regardless of wear. Operation

R
Chec kthe tyrefor foreign objects.
R Chec kwhether the wheel is losing air or the
valve is leaking.
If you are unable to rectify the damage, con-
tact aqualified specialist workshop. H
Environmental note
Check the tyre pressure regularly,atl east
every 14 days.
You will find atable of tyre pressures for var-
ious operating conditionsont he inside of
your vehicle's fuel filler flap.
Operation with the emergency spare
wheel(Y page 351).
The table inside the fuel filler flap may state
tyre pressures for different load conditions.
These are defined in the table as different
numbers of passengers and amounts of lug-
gage. The actual number of seats may vary;
for more information,p lease refer to the vehi-
cle's registration documents.
If tyre sizes are not specified, the tyre pres-
sures stated on the tyre pressure information
label apply for all tyres approved for this vehi-
cle. If
at yre size precedes atyre pressure, the
following tyre pressure information is only
valid for that tyre size.
Use asuitable pressure gauge to check the
tyre pressure. The outer appearance of atyre
does not permit any reliablec onclusion about
the tyre pressure. On vehicles fitted with the
electronic tyre pressure monitor, the tyre pressure can be checked using the on-board
computer.
If possible, only correct tyre pressures when
the tyres are cold.
The tyres are cold:
R
if the vehicle has been parked with the tyres
out of direct sunlight for at least three
hours and
R if the vehicle has not been driven further
than 1.6 km
Depending on the ambient temperature, the
speed at which you are driving and the load
on the tyres, the tyre temperature and thus
the tyre pressure change by approximately
10 kPa per 10 †(0.1 bar/1.5 psi). Take this
into account whe nchecking the pressure of
warm tyres. Only correct the tyre pressure if
it is too low for the current operating condi-
tions.
Driving with tyre pressure that is too high or
too low can:
R shorten the service life of the tyres
R cause increased tyre damage
R have anegative effect on handling charac-
teristics and thus the driving safety (e.g.
aquaplaning)
i The tyre pressure values given for low
loads are minimum values which offer you
good ride comfort characteristics.
However, you can also use the values given
for higher loads. These are permissible and
will not adversely affect the running of the
vehicle. Tyrep
ressur eloss warning system
Important safety notes While the vehicle is in motion, the tyre pres-
sure loss warning system monitors the set
tyre pressure using the rotational speed of
the wheels. This enables the system to detect
significant pressure loss in
atyre. If the speed
of rotation of awheel changes as aresult of
al oss of pressure, acorresponding warning 332
