Wear indicators
The original tyres on your vehicle have 1.6 mm high “tread wear indicators”
⇒ Fig. 176, 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 253.
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. 177. The useful life of all the
tyres will then be 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 a Technical Service.
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 256. 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 a Technical Service.
● 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/ASR on (Electronic Stability Control), or switch it
on ⇒  page 197.
– Continue driving carefully and slowly (80 km/h (50 mph) maxi-
mum).
– Avoid sudden manoeuvres and sharp turns.
– Avoid driving over obstacles (for example kerbs) or potholes.
– Pay attention if the ESC/ASR activates often, if smoke comes
from the tyres or there is a smell of rubber, the vehicle vibrates
or there are clattering noises. If any of these occur, stop the ve-
hicle.
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 (50 miles) and if the circumstances are fa-
vourable (for example, low load), even more. The damaged tyre should be changed as soon as possible. The rim should
be checked in a specialised workshop to detect possible damage and re-
place it if necessary. We recommend you contact Technical Service. If more
than one tyre is being used under emergency conditions, this reduces the
distance 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. 

260Wheels and tyres
Winter tyres
Winter tyres will improve the vehicles handling on snow and
ice.
In winter conditions winter tyres will considerably improve the vehicle's han-
dling. The design of summer tyres (width, rubber compound, tread pattern)
gives less grip on ice and snow.
The winter tyres must be inflated to a pressure 0.2 bar (2.9 psi / 20 kPa)
higher than the pressures specified for summer tyres (see sticker on fuel
tank flap).
Winter tyres must be fitted on all four wheels.
Information on permitted winter tyre sizes can be found in the vehicle's reg-
istration documentation. Use only radial winter tyres. All tyre sizes listed in
the vehicle documentation also apply to winter tyres.
Winter tyres lose their effectiveness when the tread is worn down to a depth
of 4 mm.
The speed rating code ⇒  page 258, New tyres and wheels determines the
following speed limits for winter tyres: ⇒ 
max. 160 km/h (130 mph)
max. 180 km/h (130 mph)
max. 190 km/h (130 mph)
max. 210 km/h (130 mph)
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 Technical Service. The legal requirements 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. Q
S
T
H If you have a flat tyre, please refer to the notes on the spare wheel
⇒ page 258, 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 296.
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 Technical Service, must then be
fitted over the wheel bolts.
All-wheel drive : Where snow chains are compulsory on certain roads, this
normally also applies to cars with all-wheel drive. Snow chains may only be
fitted to the front wheels (also on vehicles with all-wheel drive).
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. 

If 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 temporary spare wheel has been specially designed for your ve-
hicle, thus, it cannot be changed with the temporary spare wheel from an-
other 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 wheel 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 after fitting the temporary spare wheel. The temporary spare wheel
pressure for dimensions 125/70R16 125/70R18 135/90R16 is 4.2 bar
(61 psi / 420 kPa); for all other tyre dimensions please refer to the label
on the fuel cap. Failure to do so could result in an accident.
● Do not drive faster than 80 km/h (50 mph), since higher speeds can
cause an accident.
● Avoid heavy acceleration, hard braking and fast cornering. Risk of ac-
cident.
WARNING (Continued)
● Never use more than one temporary spare wheel 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.

Tyre repair kit*
The tyre repair kit (for vehicles not including a temporary
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 product 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 pene-
tration 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 product. 

If and when
10.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.
11.When the engine is running, disconnect the leads in reverse or- der 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 235, 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 lean on 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. 

290If 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 287.
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. General notes
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 towline anchorages 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. 

Description of specifications
The fuel consumption and CO 2 emissions do not depend only on the per-
formance of the vehicle, they can also differ from the established values de-
pending on other factors such as driving style, road conditions, traffic con-
ditions, environmental conditions, load and number of passengers.
Calculation of fuel consumption
The consumption values have been calculated based on measurements per-
formed or supervised by certified CE laboratories according to the latest ver-
sion of directives 715/2007/EC and 80/1268/CEE (for more information
consult the European Union Publications Office at EUR-Lex: © European Un-
ion, http://eur-lex.europa.eu/en/index.htm) and are valid for the kerb
weight indicated for the vehicle.
Note
In practice, and considering all the factors mentioned here, consumption
values can differ from those calculated in the current European regulations. 
Weights
Kerb weight refers to the basic model with a fuel tank filled to 90% capacity
and without optional extras. The figure quoted includes 75 kg to allow for
the weight of the driver.
For special versions and optional equipment fittings or for the addition of
accessories, the weight of the vehicle will increase ⇒ 
.
WARNING
● Please note that the centre of gravity may shift when transporting
heavy objects; this may affect vehicle handling and lead to an accident.
Always adjust your speed and driving style to suit road conditions and re-
quirements.
● Never exceed the gross axle weight rating or the gross vehicle weight
rating. If the allowed axle load or the allowed total weight is exceeded,
the driving characteristics of the vehicle may change, leading to acci-
dents, injuries and damage to the vehicle.

Towing a trailer Trailer weights
Trailer weight
The trailer weights and drawbar loads approved are selected in intensive tri-
als according to precisely defined criteria. The approved trailer weights are
valid for vehicles in the EU for maximum speeds of 80 km/h (50 mph) (in
certain circumstances up to 100 km/h (62 mph)). The figures may be differ-
ent in other countries. All data in the official vehicle documentation takes
precedence over these data at all times ⇒ 
.
Drawbar loads
The maximum permitted drawbar load on the ball joint of the towing bracket
must not exceed 75 kg.
In the interest of road safety, we recommend that you always tow approach-
ing the maximum drawbar load. The response of the trailer on the road will
be poor if the drawbar load is too small.
If the maximum permissible drawbar load cannot be met (e.g. with small,
empty and light-weight single axle trailers or tandem axle trailers with a 
Safety FirstOperating instructionsPractical TipsTechnical Specifications

296Description of specifications
wheelbase of less than 1 metre), a minimum of 4% of the actual trailer
weight is legally required for the drawbar load.
WARNING
● For safety reasons, you should not drive at speeds above 80 km/h (50
mph) when towing a trailer. This also applies to countries where higher
speeds are permitted.
● Never exceed the maximum trailer weights or the drawbar load. If the
permissible axle load or the permissible total weight is exceeded, the
driving characteristics of the vehicle may change, leading to accidents,
injuries and damage to the vehicle.

Wheels
Tyre pressure, snow chains, wheel bolts
Tyre pressures
The sticker with the tyre pressure values can be found on the inside of the
fuel tank flap. The tyre pressure values given there are for cold tyres. Do not
reduce the slightly raised pressures of warm tyres ⇒ 
.
Snow chains
Snow chains may be fitted only to the front wheels.
Consult the section “wheels” of this manual.
Wheel bolts
After the wheels have been changed, the tightening torque of the wheel
bolts should be checked as soon as possible with a torque wrench ⇒ 
.
The tightening torque for steel and alloy wheels is 120 Nm.
WARNING
● Check the tyre pressure at least once per month. Checking the tyre
pressure is very important. If the tyre pressure is too high or too low,
there is an increased danger of accidents, particularly at high speeds.
● If the tightening torque of the wheel bolts is too low, they could loos-
en while the vehicle is in motion. Risk of accident! If the tightening tor-
que is too high, the wheel bolts and threads can be damaged.
Note
We recommend that you ask your Technical Service for information about
appropriate wheel, tyre and snow chain size. 
