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, meanin gthe tyres may
wear down to the minimum tyre tread depth

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.
Check wheels and tyres for damage at least
onc eam onth. Check wheels and tyres 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 the tyres
R deformation or severe corrosion on wheels
Regularly chec kthe tyre tread depth and the
condition of the tread across the whole width of
the tyre (Y page 354).Ifnecessary, turn the
fron twheels to full lock in order to inspec tthe
inne rside of the tyre surface.
All wheels must have avalve cap to protect the
valve against dirt and moisture. Do not fit any-
thin gontot he valve other than the standard
valve cap or other valve caps approved for your vehicle by Mercedes-Benz.Don ot fit any other
valve caps or systems ,e.g. tyre pressure moni-
torin gsystems.
Regularly chec kthe pressure of all the tyres,
particularly prior to long trips. Adjust the tyre
pressure as necessary (Y page 356).
Observe the notes on the emergency spare
wheel (Y page 367). The servic
elife of tyres depends on various fac-
tors ,includin gthe following:
R driving style
R tyre pressure
R mileage Notes on the tyr
etread G
WARNING
Insufficien ttyre 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 arisk of accident.
If the tyre pressure is too high or too low, tyres may exhibit differen tlevels of wear at differ-
ent location sonthe tyre tread. Thus, you
should regularly chec kthe 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
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 ar isk of accident.
Therefore, only use tyre types and sizes
approved for your vehicle model. Observe the
tyre load ratin gand speed ratin grequired for
your vehicle.
Pay special attention to country-specific
requirements for tyre approval. These require-
ment scan stipulate aspecific 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 354

ressure loss warning system
General notes While the vehicle is in motion
,the tyre pressure
loss warning system monitors the set tyre pres-
sure using the rotational speed of the wheels.
This enables the system to detect significant
pressure loss in atyre. If the speed of rotation of
aw heel changes as aresult of aloss of pressure,
ac orresponding warning message will appear in
the multifunction display.
You can recognise the tyre pressure loss warn-
ing by the Run Flat Indicator active

Restart with OK Restart with OK message which appears in
the Service
Service menu of the multifunction display.
Information on the message display can be
found in the "Restarting the tyre pressure loss
warning system" section (Y page 358).
Important safety notes The tyre pressure warning system does not warn
you of an incorrectly set tyre pressure. Observe the notes on the recommended tyre pressure
(Y page 356).
The tyre pressure loss warning does not replace the need to regularly check the tyre pressures.
An even loss of pressure on several tyres at the
same time cannot be detected by the tyre pres-
sure loss warning system.
The tyre pressure monitor is not able to warn
you of asudden loss of pressure, e.g. if the tyre
is penetrated by aforeign object .Inthe event of
as udden loss of pressure, bring the vehicle to a
halt by braking carefully. Avoid abrupt steering
manoeuvres.
The function of the tyre pressure loss warning
system is limited or delayed if:
R snow chains are fitted to your vehicle's tyres.
R road conditions are wintry.
R you are driving on sand or gravel.
R you adopt avery sporty driving style (corner-
ing at high speeds or driving with high rates of
acceleration).
R you are towing avery heavy or large trailer. R
you are driving with aheavy load (in the vehi-
cle or on the roof).

the respective operating conditions. The rec-
ommended tyre pressures can be found in the

The tyre pressure loss warning system can
only give reliable warnings if you have set the correc ttyre pressure. If an incorrect tyre
pressure is set, these incorrect values will be
monitored.

If the whee lpositions on the vehicl eare inter-
changed ,the tyre pressures may be displayed
for the wrong positions for ashort time. After a
few minutes of driving, this is rectified and the
tyre pressures are displayed for the correct

Restarting the tyre pressure monitor When you restart the tyre pressure monitor, all
existing warning messages are deleted and the
warning lamp sgoout. The monitor uses the cur-
rently set tyre pressures as the reference values
for monitoring. In most cases, the tyre pressure monitor willa utomatically detect the new refer-
ence values after you have changed the tyre
pressure. However, you can alsos et reference
values manually as described here. The tyre
pressure monitor then monitors the new tyre
pressure values.

WARNING
Oiled or greased wheel bolts or damaged
wheel bolts/hub threads can cause the wheel bolts to come loose. As aresult, you could
lose awheel while driving. There is arisk of
accident.
Never oil or grease wheel bolts. In the event of damage to the threads, contact aqualified
specialist workshop immediately. Have the
damaged wheel bolts or hub threads
replaced/renewed. Do not continue driving. G
WARNING
If you tighten the wheel bolts or wheel nuts
when the vehicle is raised, the jack could tip
over. There is arisk of injury.
Only tighten the wheel bolts or wheel nuts
when the vehicle is on the ground.
It is imperative to observe the instructions and
safety notes on "Changing awheel"
(Y page 361).
Only use wheel bolts that have been designed
for the wheel and the vehicle. For safety rea-
sons, Mercedes-Benz recommends that you
only use wheel bolts which have been approved for Mercedes-Benz vehicles and the respective
wheel.
! Mercedes AMG vehicles with ceramic-
brak edisc: during removal and repositioning
of the wheel, the wheel rim can strik ethe
ceramic-brak edisc and damage it. Therefore,
take precaution sand have asecon dperson

Important safety notes G
WARNING
If windscreen washer concentrate comes into contact with hot components of the engine or
the exhaust system, it can ignite. There is a
risk of fire and injury.
Make sure the windscreen washer concen-
trated oes not come into contact with the filler
neck.
! Only use washer fluid that is suitable for
plastic lamp lenses, e.g. MB SummerFit or MB
WinterFit. Unsuitable washer fluid could dam-
age the plastic lenses of the headlamps.
! Only the washer fluids SummerFit and Win-
terFit can be mixed. Otherwise, the spraying
nozzles could become blocked.
Do not use distilled or de-ionised water as the
level sensor may be triggered erroneously.
When handling washer fluid, observe the impor- tant safety notes on service products
(Y page 371).
At temperatures above freezing:
X Fill the washer fluid reservoir with amixture of
water and washer fluid, e.g. MB SummerFit.
Mix 1part MB SummerFit to 100 parts water.
At temperatures below freezing:
X Fill the washer fluid reservoir with amixture of
water and washer fluid, e.g. MB WinterFit.
For the correc tmixing ratio refer to the infor-
mation on the antifreeze reservoir.
