ESP
®
assists the driver when pulling away on
wet or slippery roads. ESP ®
can also stabilise
the vehicle during braking.
ETS (Electronic Traction System) i
Observe the "Important safety notes" sec-
tion (Y page 54).
ETS 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. In addition, more drive torque is transfer-
red to the wheel or wheels with traction.
Traction control remains active if you deactivate
ESP ®
.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 54). G
WARNING
If ESP ®
is malfunctioning, ESP ®
is unable to
stabilise the vehicle. In addition, other driving
safety systems are switched off. This increa-
ses the risk of skidding and an accident.
Drive on carefully. Have ESP ®
checked at a
qualified specialist workshop.
When ESP ®
is deactivated, the åESP®
OFF
warning lamp lights up continuously.
When SPORT handling mode is activated, the
M warning lamp lights up in the instrument
cluster.
When the åandh warning lamps light up
continuously, ESP ®
is not available due to a mal-
function.
Observe the information on warning lamps
(Y page 197) and display messages which may
be shown in the instrument cluster
(Y page 172).
Only use wheels with the recommended tyre
sizes. Only then will ESP ®
function properly. Characteristics of ESP
® General notes
If the ÷ ESP warning lamp goes out before
beginning the journey, ESP ®
is automatically
active.
If ESP ®
intervenes, the ÷ESP®
warning lamp
flashes in the instrument cluster.
If ESP ®
intervenes:
X Do not deactivate ESP ®
under any circum-
stances.
X when pulling away, only depress the acceler-
ator pedal as far as is necessary.
X Adapt your driving style to suit the prevailing
road and weather conditions.
ECO start/stop function
The ECO start/stop function switches the
engine off automatically if the vehicle stops
moving. When pulling away again, the engine
starts automatically. ESP ®
remains in its previ-
ously selected status. Example:if ESP®
was
deactivated before the engine was switched off,
ESP ®
remains deactivated when the engine is
switched on again.

WARNING
If wheels and tyres of the wrong size are used, the wheel brakes or suspension components
may be damaged. There is a risk of an acci-
dent.
Always replace wheels and tyres with those
that fulfil the specifications of the original
part.
When replacing wheels, make sure to fit the
correct:

R type G
WARNING
A flat tyre severely impairs the driving, steer-
ing and braking characteristics of the vehicle.
There is a risk of accident.
Tyres without run-flat characteristics:
R do not drive with a flat tyre.
R immediately replace the flat tyre with your
emergency spare wheel or spare wheel, or
consult a qualified specialist workshop.
Tyres with run-flat characteristics:
R pay attention to the information and warn-
ing notices on MOExtended tyres (tyres
with run-flat characteristics).
Accessories that are not approved for your vehi-
cle by Mercedes-Benz or are not being used cor- rectly can impair the operating safety.
Before purchasing and using non-approved
accessories, visit a qualified specialist work-
shop and enquire about:
R suitability
R legal stipulations
R factory recommendations Information on the sizes and types of wheels and
tyres for your vehicle can be found under
"Wheel/tyre combinations" (Y page 272).
Information on tyre pressure can be found:
R in the tyre pressure table in the fuel filler flap
(Y page 118)
R in the "Tyre pressure" section
Modification work on the brake system and
wheels is not permitted. The use of spacers or
brake dust shields is not permitted. This inva-
lidates the general operating permit for the vehi- cle.
i Further information on wheels and tyres can
be obtained at any qualified specialist work-
shop. Operation
Information on driving
Check the tyre pressures when the vehicle is
heavily laden and adjust prior to a trip.
While driving, pay attention to vibrations, noises
and unusual handling characteristics, e.g. pull-
ing to one side. This may indicate that the
wheels or tyres are damaged. If you suspect that a tyre is defective, reduce your speed immedi-
ately. Stop the vehicle as soon as possible to
check the 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 a qualified specialist workshop.
When parking your vehicle, make sure not to
squash the tyre sidewalls. If this cannot be avoi- ded, drive slowly over obstacles, e.g. kerbs, and
only at an obtuse angle. You could otherwise
damage the wheel rims and tyres. Notes on high performance tyres
G
WARNING
Due to the special tyre tread in combination
with the optimised rubber compound, there is an increased risk of aquaplaning and skidding
on a damp or wet road surface. Tyre grip is
also noticeably reduced at low outside tem-
peratures and low tyre operating tempera-
tures. There is a risk of an accident. Operation
261Wheels and ty res
Z

Turn on ESP
®
and adapt your driving style
accordingly. When the outside temperature
falls below 10 †, use M+S tyres.
i Different driving styles may lead to higher
levels of tyre wear, meaning the tyres may
wear down to the minimum tyre tread depth
after less mileage. Regular checking of wheels and tyres
G
WARNING
Damaged tyres can cause tyre inflation pres-
sure loss. As a result, you could lose control of your vehicle. There is a risk of accident.
Check the tyres regularly for signs of damageand replace any damaged tyres immediately.
Check wheels and tyres for damage at least
once a month. Check wheels and tyres after
driving off-road or on rough roads. Damaged
wheels can cause a loss 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 the 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 262). If necessary, turn the
front wheels to full lock in order to inspect the
inner side of the tyre surface.
All wheels must have a valve cap to protect the
valve against dirt and moisture. Do not fit any-
thing onto the valve other than the standard
valve cap or other valve caps approved for your vehicle by Mercedes-Benz. Do not fit any other
valve caps or systems, e.g. tyre pressure moni-
toring systems.
Regularly check the pressure of all the tyres,
particularly prior to long trips. Adjust the tyre
pressure as necessary (Y page 264).
Observe the notes on the emergency spare
wheel (Y page 273). The service life of tyres depends on various fac-
tors, including the following:
R driving style
R tyre pressure
R mileage Notes on the tyre tread
G
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 particularwhere speed is not adapted to suit the driving
conditions. There is a risk 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: 3 mm
R M+S tyres: 4 mm
For safety reasons, replace the tyres before
the legally prescribed limit for the minimum
tyre tread depth is reached. Selecting, fitting and replacing tyres
G
WARNING
Exceeding the stated tyre load-bearing capa-
city and the approved maximum speed could
lead to tyre damage or the tyre bursting. There is a risk of accident.
Therefore, only use tyre types and sizes
approved for your vehicle model. Observe the
tyre load rating and speed rating required for your vehicle.
Pay special attention to country-specific
requirements for tyre approval. These require-
ments can stipulate a specific tyre type for your
vehicle. Furthermore, the use of certain tyre
types in certain regions and areas of operation
can be highly beneficial. You can find further 262
OperationWheels and tyres

information regarding tyres at specialist tyre
retailers, at qualified specialist workshops or at any Mercedes-Benz Service Centre.
R Only fit tyres and wheels of the same type and
make.
Exception: it is permissible to fit a different
type or make in the event of a flat tyre.
R Only fit tyres of the correct size onto the
wheels.
R Run in new tyres at moderate speeds for the
first 100 km. They only reach their full per-
formance after this distance.
R Do not drive with tyres which have too little
tread depth. This otherwise significantly
reduces the traction on wet roads (aquaplan-
ing).
R Replace the tyres after six years at the latest,
regardless of wear.
Observe the notes on the emergency spare
wheel (Y page 273). Winter operation
General notes
Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
Observe the notes in the "Changing a wheel"
section (Y page 267). Driving with summer tyres
At temperatures below +7 †, summer tyres lose
elasticity and therefore traction and braking
power. Change the tyres on your vehicle to
M+S tyres. Using summer tyres at very cold
temperatures could cause tears to form,
thereby damaging the tyres permanently.
Mercedes-Benz cannot accept responsibility for
this type of damage. G
WARNING
Damaged tyres can cause tyre inflation pres-
sure loss. As a result, you could lose control of your vehicle. There is a risk of accident.
Check the tyres regularly for signs of damageand replace any damaged tyres immediately. M+S tyres
G
WARNING
M+S tyres with a tyre tread depth of less than 4 mm are not suitable for use in winter as they
do not provide sufficient traction. There is a
risk of accident.
M+S tyres with a tread depth of less than
4 mm must be replaced.
At temperatures below +7 †, use winter tyres or all-season tyres. Both types of tyre are identified
by the M+S marking.
Only winter tyres bearing the isnowflake
symbol in addition to the M+S marking provide
the best possible grip in wintry road conditions. Only these tyres will allow driving safety sys-
tems such as ABS and ESP ®
to function opti-
mally in winter. These tyres have been devel-
oped specifically for driving in snow.
Use M+S tyres of the same make and tread on all
wheels to maintain safe handling characteris-
tics.
Always observe the maximum permissible
speed specified for the M+S tyres you have fit-
ted.
If you fit M+S tyre sthat have a lower maximum
permissible speed than that of the vehicle, affix
an appropriate warning label in the driver's field
of vision. This can be obtained at a qualified
specialist workshop.
Under these circumstances, you should also
restrict the maximum design speed of the vehi- cle using permanent SPEEDTRONIC so that it
does not exceed the maximum permissible
speed for the M+S tyres (Y page 130).
When you have fitted the M+S tyres:
X Check the tyre pressures (Y page 264).
X Restart the tyre pressure monitor
(Y page 267).
Information on driving with an emergency spare
wheel (Y page 273). Snow chains

WARNING
If you have fitted snow chains to the front
wheels, they may scrape against the vehicle
body or chassis components. This could Winter operation

the "Emergency spare wheel" section
(Y page 273).
Additionally, the tyre pressure table may also
state tyre pressures for different load condi-
tions. 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, please refer to the vehicle's
registration documents.
If tyre sizes are not specified, the tyre pressures stated on the tyre pressure table apply for all
tyres approved for this vehicle. If a tyre size precedes a tyre pressure, the fol-
lowing tyre pressure information is only valid for that tyre size.
Use a suitable pressure gauge to check the tyre
pressure. The outer appearance of a tyre does
not permit any reliable conclusion about the tyre
pressure. You can also check the tyre pressure
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
vehicle speed and the load on the tyres, the tyre temperature and thus the tyre pressure changes by approximately 10 kPa (0.1 bar/1.5 ps i) per
10 †. Take this into account when checking the
pressure of warm tyres. Only correct the tyre pressure if it is too low for the current operating
conditions.
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 a negative effect on handling character-
istics and thus driving safety (e.g. aquaplan-
ing)
The tyre pressure values given for low loads are
minimum values which offer you good ride com- fort 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.
This improves the ride comfort of your vehicle;
however, fuel consumption may increase
slightly. Tyre pressure monitor
General notes If a tyre pressure monitor system is fitted, the
vehicle's wheels have sensors fitted that moni-
tor the tyre pressures in all four tyres. The tyre
pressure monitor warns you if the pressure
drops in one or more of the tyres. The tyre pres- sure monitor only functions if the corresponding sensors are fitted to all wheels.
Information on tyre pressures is shown in the
multifunction display. After a few minutes of
driving, the current tyre pressure of each tyre is
shown in the Service Servicemenu of the multifunction
display; see illustration (example). For further information on displaying this mes-
sage, refer to the "Checking the tyre pressure
electronically" section (Y
page 266). Tyre pressure
