Adaptive brake lamps
If you brake sharply from a speed of more
than 50 km/h or if braking is assisted by BAS
or BA SPLUS, the brake lamps flash rapidly.
In this way, traffic travelling behind you is
warned in an even more noticeable manner.
If you brake sharply from a speed of more
than 70 km/h to a standstill, the hazard warn-
ing lamps are activated automatically. If the
brakes are applied again, the brake lamps
lightu p continuously. The hazard warning
lamps switch off automatically if you travel
faster than 10 km/ h.You can also switch off
the hazard warning lamps using the hazard
warning switch button (Y page 99).
i Adaptive brake lamps are only available in
certain countries. ESP
®
(Electronic Stability Program)
Important safety notes G
WARNING
If the ÷ warning lamp in the instrument
cluster flashes, proceed as follows:
R do not deactivate ESP ®
under any circum-
stances.
R only depress the accelerator pedal as far as
necessary when pulling away.
R adapt your driving style to suit the prevail-
ing road and weathe rconditions.
Otherwise, the vehicle could go into a skid.
ESP ®
cannot reduce the risk of an accident if
you drive too fast. ESP ®
cannot override the
laws of physics.
! Switch the ignition off when:
R the electric parking brake is being tested
using a brake dynamometer.
R the vehicle is being towed with the front/
rear axle raised.
Application of the brakes by ESP ®
may oth-
erwise destroy the brake system. If ESP
®
detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilise the
vehicle. If necessary, the engine output is also
modified to keep the vehicle on the desired
course within physical limits. ESP ®
assists
the driver when pulling away on wet or slip-
pery roads. ESP ®
can also stabilise the vehi-
cle during braking.
If ESP ®
intervenes, the ÷ESP®
warning
lamp flashes in the instrument cluster.
i Observe the "Important safety notes" sec-
tion (Y page 62).
i Only use wheels with the recommended
tyre sizes. Only then will ESP ®
function
properly.
Traction control 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.
Traction control remains active if you deacti-
vate ESP ®
.
i Observe the "Important safety notes" sec-
tion (Y page 62).
Deactivating/activating ESP ® G
WARNING
ESP ®
is deactivated if the åwarning lamp
in the instrument cluster lights up continu-
ously when the engine is running.
If the ÷ warning lamp and åwarning
lamp are lit continuously, ESP ®
is not availa-
ble due to a malfunction.
There is an increased risk of your vehicle skid-
ding in certain situations.
You should always adapt your driving style to
suit the prevailing road and weather condi-
tions. 66

Steering wheel
Important safety notes
G
WARNING
Only adjust the steering wheel when the vehi-
cle is stationary and make sure that it is
locked securely in position before driving off.
Driving without the steering wheel adjust-
ment mechanism being locked in position
may cause the steering wheel to move unex-
pectedly. As a result, the driver could lose
control of the vehicle. Before driving off make
sure that the steering wheel is properly locked
in position by trying to move it up and down. Adjusting the steering wheel

Adjusting the exterior mirrors G
WARNING
The exterior mirrors reduce the size of the
image. Objects are actually closer than they
appear. You could misjudge the distance from
vehicles driving behind and cause an acci-
dent, e.g. when changing lane. For this rea-
son, make sure of the actual distance from the
vehicle driving behind by glancing over your
shoulder. Mirrors
91Seats, steering wheel and mirrors Z

In addition to the vehicle load, the driving dis-
tance possible depends upon:
R speed
R road condition
R outside temperature
The driving distance possible in run-flat mode
may be reduced by extreme driving condi-
tions/manoeuvres, or it can be increased
through a moderate style of driving.
The maximum permissible distance which
can be driven in run-flat mode is counted from
the moment the tyre pressure loss warning
appears in the multifunction display.
You must not exceed a maximum speed of
80 km/h.
i When replacing one or all tyres, make
sure that you only use tyres marked
MOExtended. Also ensure that they are of
the specified size for the vehicle.
i Vehicles with MOExtended tyres are not
equipped with a TIREFIT kit at the factory.
It is therefore recommended that you addi-
tionally equip yourv ehicle with a TIREFIT kit
if you fit tyres that do not feature run-flat
characteristics, e.g. winter tyres. A TIREFIT
kit is available, for example, from a qualified
specialist workshop. TIREFIT kit
Using the TIREFIT kit TIREFIT is a tyre sealant.
You can use TIREFIT to seal punctures of up
to 4 mm, 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 sufficien tbreakdown 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 a flat tyre.
There is a risk of accident.
Do not drive any further. Contact a qualified
specialist workshop. G
WARNING
The tyre sealant is harmfu land 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 a risk of injury.
If you come into contact with the tyre sealant,
observe the following:
R Rinse off the tyre sealant from your skin
immediately with water.
R If the tyre sealant comes into contact with
your eyes, immediately rinse them thor-
oughly with clean water.
R If tyre sealant is swallowed, immediately
rinse your mouth ou tthoroughly and drink
plenty of water. Do not induce vomiting,
and seek medical attention immediately.
R Immediately change out of clothing which
has come into contact with tyre sealant.
R If an allergic reaction occurs, seek medical
attention immediately. Flat tyre

Useful information
i This Owner's Manual describes all models
and all standard and optional equipment
available to your vehicle at the time of pub-
lication of the Owner's Manual. Country-
specific deviations are possible. Please
note that your vehicle may not be equipped
with all features described. This also
applies to safety-relevan tsystems and
functions.
i Please read the information on qualified
specialist workshops (Y page 22).Important safety notes
G
WARNING
If wheels and tyres of the wrong size are used,
the wheel brakes or suspensio ncomponents
may be damaged. There is arisk of accident.
Always replace wheels and tyres with 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 a risk of accident.
Tyres without run-flat characteristics:
R do not drive with aflat 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
vehicle by Mercedes-Ben zorare not being
used correctly 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 dimensions and types of
wheels and tyres for yourv ehicle can be
found in the "Wheel/tyre combinations" sec-
tion (Y page 302).
Information on air pressure for the tyres on
your vehicle can be found:
R on the tyre pressure label on the fuel filler
flap
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
Notes on driving
R Check the tyre pressures when the vehicle
is heavily laden and, if necessary, adjust.
R While driving, pay attention to vibrations,
noises and unusual handling characteris-
tics, e.g. pulling to one side. This may indi-
cate that the wheels or tyres are damaged.
If you suspect that a tyre 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 wheels and tyres
checked at a qualified specialist workshop.
R When parking your vehicle, make sure that
the tyres do not get deformed by the kerb
or other obstacles. If it is necessary to drive 292
OperationWheels and tyres

over kerbs, speed humps or similar eleva-
tions, try to do so at an obtuse angle. Oth-
erwise, the tyres, particularly the sidewalls,
can get damaged. Notes on regularly inspecting 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 damage
and replace any damaged tyres immediately.
R Regularly check the wheels and tyres of
your vehicle for damage (e.g. cuts, punctu-
res, tears, bulges on tyres and deformation,
cracks or severe corrosion on wheels), at
least every 14 days, as well as after driving
off-road or on rough roads. Damaged
wheels can cause a loss of tyre pressure.
R Regularly check the tyre tread depth and
the condition of the tread across the whole
width of the tyre (Y page 293). If neces-
sary, turn the front wheels to full lock in
order to inspect the inner side of the tyre
surface.
R All wheels must have a valve cap to protect
the valve against dirt and moisture. Do not
fit anything onto the valve (such as tyre
pressure monitoring systems) other than
the standard valve cap or other valve caps
approved by Mercedes-Benz for your vehi-
cle.
R You should therefore regularly check the
pressure of all your tyres, particularly prior
to long trips, and correc tthe pressure as
necessary (Y page 295).
Observe the notes on the emergency spare
wheel (Y page 304). The service life of tyres depends on various
factors, including the following:
R
driving style
R tyre pressure
R mileage 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 particular
where 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.. Notes on selecting, fitting and replac-
ing tyres
R Only fit tyres and wheels of the same type
and make.
R Only fit tyres of the correct size onto the
wheels.
R After fittingn ew tyres, run them in at mod-
erate speeds for the first 100 km, as they
only reach their full performance after this
distance.
R Do not drive with tyres which have too little
tread depth, as this significantly reduces
the traction on wet roads (aquaplaning).
R Replace the tyres after six years at the lat-
est, regardless of wear. Operation
293Wheels and tyres Z

R
Check the tyre for 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 a qualified specialist workshop. H
Environmental note
Check the tyre pressure regularly, at least
every 14 days.
You will find a table of tyre pressures for var-
ious operating conditions on the inside of
your vehicle's fuel filler flap.
Operation with a trailer: the applicable
value for the rear tyres is the maximum tyre
pressure value stated in the table inside the
fuel filler flap.
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, please 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 a tyre size precedes a tyre pressure, the tyre
pressure information following 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. 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 you are driving at and the load on the
tyres, the tyre temperature may change and
thereby the tyre pressure: 10 kPa (0.1 bar/
1.5 psi) 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 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. Tyre pressure loss 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 a tyre. If the speed
of rotation of a wheel changes as a result of
a loss of pressure, a corresponding warning
message will appearint he multifunction dis-
play. 296
