Wear indicators
The original tyres on your vehicle have 1.6 mm high “tread wear indicators”
⇒ fig. 152, running across the tread. Depending on the make, there will be
6 to 8 of them evenly spaced around the tyre. Markings on the tyre sidewall
(for instance the letters “TWI” or other symbols) indicate the positions of
the tread wear indicators. The minimum tread depth required by law is
1.6 mm (measured in the tread grooves next to the tread wear indicators).
Worn tyres must be replaced. Different figures may apply in export countries
⇒ 
.
Tyre pressure
Incorrect tyre pressure causes premature wear and could cause tyre blow-
out. For this reason, the tyre pressure should be checked at least once per
month ⇒ page 233.
Driving style
Fast cornering, heavy acceleration and hard braking all increase tyre wear.
Changing wheels around
If the front tyres are worn considerably more than the rear ones it is advisa-
ble to change them around as shown ⇒ fig. 153. All the tyres will then last
for about the same time.
Wheel balance
The wheels on new vehicles are balanced. However, various factors encoun-
tered in normal driving can cause them to become unbalanced, which re-
sults in steering vibration.
Unbalanced wheels should be rebalanced, as they otherwise cause exces-
sive wear on steering, suspension and tyres. A wheel must also be reba-
lanced when a new tyre is fitted. Incorrect wheel alignment
Incorrect wheel alignment causes excessive tyre wear, impairing the safety
of the vehicle. If tyres show excessive wear, you should have the wheel
alignment checked by an Authorised Service Centre.
WARNING
There is a serious danger of accidents if a tyre bursts during driving!
● The tyres must be replaced at the latest when the tread wear indica-
tors are worn ⇒ page 236. Failure to do so could result in an accident.
Worn tyres do not grip well at high speeds on wet roads. There is also a
greater risk of aquaplaning.
● At continuously high speeds, a tyre with insufficient pressure flexes
more. This causes it to overheat. This can cause tread separation and tyre
blow-out. Risk of accident. Always observe the recommended tyre pres-
sures.
● If tyres show excessive wear, you should have the running gear
checked by an Authorised Service Centre.
● Keep chemicals such as oil, fuel and brake fluid away from tyres.
● Damaged wheels and tyres must be replaced immediately!
For the sake of the environment
Under-inflated tyres will increase fuel consumption. 

Wheels and tyres
Run-flat tyres
Run-flat tyres allow you to continue driving even with a
punctured tyre, in the majority of cases.
In vehicles that are factory-fitted with run-flat tyres 1)
the loss of tyre
pressure is indicated on the instrument panel.
Driving with run-flat tyres (emergency running)
– Leave the ESC (ESP)/ASR (TCS) (Electronic Stability Control) acti-
vated, or activate it ⇒ page 183.
– Continue driving carefully and slowly (80 km/h maximum).
– Avoid sudden manoeuvres and sharp turns.
– Avoid driving over obstacles (for example kerbs) or potholes.
– Look out for the ESC (ESP)/ASR (TCS) intervening often, smoke
coming from the tyres or the smell of rubber, the vehicle vibrat-
ing or a clattering noise. If any of these occur, stop the vehicle.
The run-flat tyres have a tag on the side of the tyre, with the description:
“DSST”, “Eufonia”, “RFT”, “ROF”, “RSC”, “SSR” or “ZP”.
The sides of this type of tyre are reinforced. When the tyres lose air they are
supported on the sides (emergency driving).
The loss of pressure in the tyre is shown on the instrument panel. You can
then drive a maximum of 80 km and if the circumstances are favourable (for
example, low load), even more.
The damaged tyre should be changed as soon as possible. The rim should
be checked in a specialist workshop to detect possible damage and replace it if necessary. We recommend you contact Technical Service. If more than
one tyre is being used under emergency conditions, this reduces the dis-
tance which can be travelled.
Starting driving in emergency conditions
When loss in tyre pressure is displayed on the instrument panel, this means
that at least one tyre is being driven in emergency conditions
⇒ 
.
End of emergency operation
Do not drive on if:
● smoke is coming from one of the tyres,
● there is a smell of rubber,
● the vehicle vibrates,
● there is a rattling noise.
When is it no longer possible to continue driving even using run-flat tyres?
● If one of the tyres has been severely damaged in an accident, etc. If a
tyre has been badly damaged there is a risk that parts of the tread can be
thrown off and cause damage to the fuel lines, brake pipes or fuel filler.
● It is also advisable to stop driving if severe vibrations occur, or if the
wheel starts overheating and gives off smoke.
WARNING
When driving in emergency conditions, the driving quality of the vehicle
is considerably impaired.
● The maximum permitted speed of 80 km/h is subject to road and
weather conditions. Please observe legal requirements when doing so.
● Avoid sharp turns and rapid manoeuvres, and brake earlier than usu-
al. 

240Wheels and tyres
The speed rating code ⇒ page 238, New tyres and wheels determines the
following speed limits for winter tyres: ⇒ 
max. 160 km/h
max. 180 km/h
max. 190 km/h
max. 210 km/h
In some countries, vehicles which can exceed the speed rating of the fitted
tyre must have an appropriate sticker in the driver's field of view. These
stickers are available from your Authorised Service Centre. The legal require-
ments of each country must be followed.
Do not have winter tyres fitted for unnecessarily long periods. Vehicles with
summer tyres handle better when the roads are free of snow and ice.
If you have a flat tyre, please refer to the notes on the spare wheel
⇒ page 238, New tyres and wheels.
WARNING
The maximum speed for the winter tyres must not be exceeded. Other-
wise, this could lead to tyre damage and risk of accident.
For the sake of the environment
Fit your summer tyres again as soon as possible. They are quieter, do not
wear so quickly and reduce fuel consumption. 
Snow chains
Snow chains are only permitted on front wheels and only for tyres
195/65R15 and 205/55R16. These tyres may only be fitted with fine-pitch
link chains which do not protrude more than 15 mm ⇒ page 272. For
235/35R19 tyres, the use of snow chains is not permitted. Q
S
T
H Other tyres may use fine-pitch links which do not protrude more than 9 mm,
including tension device.
Remove wheel hub covers and trim rings before fitting snow chains. For
safety reasons cover caps, available in any Authorised Service Centre, must
then be fitted over the wheel bolts.
WARNING
Snow chains should be correctly tightened in accordance with the manu-
facturer's instructions. This will prevent the chains coming into contact
with the wheel housing.
CAUTION
Remove the snow chains to drive on roads without snow. Otherwise they
will impair handling, damage the tyres and wear out very quickly.
Note
● In some countries, the speed limit for using snow chains is 50 km/h.
The legal requirements of the country should be followed.
● We recommend that you ask your Authorised Service Centre for informa-
tion about appropriate wheel, tyre and snow chain size. 

242If and when
How to use the temporary spare wheel
Should you ever have a punctured tyre, the temporary spare wheel is only
intended for temporary use until you can reach a workshop. The standard-
size road wheel should be replaced as soon as possible.
Please note the following restrictions when using the temporary spare
wheel. This spare wheel has been specially designed for your vehicle, thus,
it cannot be changed with the spare wheel from another vehicle.
No other type of tyre (normal summer or winter tyre) may be fitted on the
compact temporary spare wheel rim.
Snow chains
For technical reasons, snow chains must not be used on the compact tem-
porary spare wheel.
If you have a puncture on one of the front wheels when using snow chains,
fit the compact temporary spare in place of one of the rear wheels. You can
then attach the snow chains to the wheel taken from the rear and use this
wheel to replace the punctured front wheel.
WARNING
● The tyre pressures must be checked and corrected as soon as possi-
ble. The emergency tyre pressure for dimensions 125/70R16 125/70R18
135/90R16 is 4.2 bar; for all other tyre dimensions please refer to the la-
bel on the fuel cap. Failure to do so could result in an accident.
● Do not drive faster than 80 km/h. Higher speeds can cause an acci-
dent.
● Avoid heavy acceleration, hard braking and fast cornering. Risk of ac-
cident.
● Never use two or more compact spare tyres at the same time, risk of
accident.
● No other type of tyre (normal summer or winter tyre) may be fitted on
the compact temporary spare wheel rim.
Note
● Vehicles with Brembo brakes must never use emergency wheels. These
vehicles are supplied with a tyre repair kit. 
Tyre repair kit*
The tyre repair kit (for vehicles not including a spare wheel)
is stored under the floor panel in the luggage compartment. Your vehicle is equipped with the Tyre Mobility System “Tyre repair kit”.
The tyre repair kit consists of a container with sealing compound to repair
the puncture and a compressor to generate the required tyre pressure. The
kit will reliably seal punctures up to a size of about 4 mm caused by the
penetration of a foreign body into the tyre.
Note
● Seek professional assistance if the repair of a tyre puncture is not possi-
ble with the sealing compound. 
Wheel change Preparation work
What you must do before changing a wheel.
– If you have a flat tyre or puncture, park the vehicle as far away
from the flow of traffic as possible. Choose a location that is as
level as possible. 

If and when
11. Turn on the heater blower and heated rear window in the vehi- cle with the flat battery. This helps minimise voltage peaks
which are generated when the leads are disconnected.
12. When the engine is running, disconnect the leads in reverse order to the details given above.
Connect the battery clamps so they have good metal-to-metal contact with
the battery terminals.
If the engine fails to start, switch off the starter after about 10 seconds and
try again after about half a minute.
WARNING
● Please note the safety warnings referring to working in the engine
compartment ⇒ page 217, Working in the engine compartment.
● The battery providing assistance must have the same voltage as the
flat battery (12V) and approximately the same capacity (see imprint on
battery). Failure to comply could result in an explosion.
● Never use jump leads when one of the batteries is frozen. Danger of
explosion! Even after the battery has thawed, battery acid could leak and
cause chemical burns. If a battery freezes, it should be replaced.
● Keep sparks, flames and lighted cigarettes away from batteries, dan-
ger of explosion. Failure to comply could result in an explosion.
● Observe the instructions provided by the manufacturer of the jump
leads.
● Do not connect the negative cable from the other vehicle directly to
the negative terminal of the flat battery. The gas emitted from the battery
could be ignited by sparks. Danger of explosion.
● Do not attach the negative cable from the other vehicle to parts of the
fuel system or to the brake line.
WARNING (Continued)
● The non-insulated parts of the battery clamps must not be allowed to
touch. The jump lead attached to the positive battery terminal must not
touch metal parts of the vehicle, this can cause a short circuit.
● Position the leads in such a way that they cannot come into contact
with any moving parts in the engine compartment.
● Do not bend over the batteries. This could result in chemical burns.
Note
The vehicles must not touch each other, otherwise electricity could flow as
soon as the positive terminals are connected. 

266If and when
Towing and tow-starting
Tow-starting
The use of jump leads is preferable to tow-starting.
We recommend that you do not tow-start your vehicle. Jump-start-
ing is preferable ⇒ page 263.
However, if your vehicle has to be tow-started:
– Engage the 2nd or the 3rd gear.
– Keep the clutch pressed down.
– Switch the ignition on.
– Once both vehicles are moving, release the clutch.
– As soon as the engine starts, press the clutch and move the
gear lever into neutral. This helps to prevent driving into the
towing vehicle.
WARNING
The risk of accidents is high when tow-starting. The vehicle being towed
can easily collide with the towing vehicle.
CAUTION
When tow-starting, fuel could enter the catalytic converter and damage it. Comments
Please observe the following points if you use a tow-rope:
Notes for the driver of the towing vehicle
–
Drive slowly at first until the tow-rope is taut. Then accelerate
gradually.
– Begin and change gears cautiously. If you are driving an auto-
matic vehicle, accelerate gently.
– Remember that the brake servo and power steering are not
working in the vehicle you are towing. Brake sooner than nor-
mal and pressing the pedal gently.
Notes for the driver of the towed vehicle
– Ensure that the tow-rope remains taut at all times when towing.
Tow-rope or tow-bar
It is easier and safer to tow a vehicle with a tow-bar. You should only use a
tow-rope if you do not have a tow-bar.
A tow-rope should be slightly elastic to reduce the loading on both vehicles.
It is advisable to use a tow-rope made of synthetic fibre or similarly elastic
material.
Attach the tow-rope or the tow-bar only to the towing eyes provided or a
towing bracket.
Driving style
Towing requires some experience, especially when using a tow-rope. Both
drivers should be familiar with the technique required for towing. Inexper-
ienced drivers should not attempt to tow. 
