Winter tyres

Winter tyres improve driving safety at

temperatures below 7 °C and should

therefore be fitted on all wheels.

In accordance with country-specific

regulations, affix the speed sticker in

the driver's field of view, if the tyre

speed code is below the maximum

speed of the vehicle.

All tyre sizes are permitted as winter

tyres 3 251.

Choose a tyre appropriate for the

maximum speed of the vehicle.

The maximum speed is achievable at

kerb weight with driver (75 kg) plus

125 kg payload. Optional equipment

could reduce the maximum speed of

the vehicle.

Vehicle care

221

The tyre pressure information label

indicates the original equipment tyres

and the correspondent tyre

pressures.

The tyre pressure data refers to cold

tyres. It applies to summer and winter

tyres.

The driver is responsible for correct

adjustment of tyre pressure.

Directional tyres

Directional tyres should be mounted

so that they rotate in the correct

direction. The proper rotation

direction is indicated by a symbol

(e.g. an arrow) on the sidewall.

9 Warning

If the pressure is too low, this can

result in considerable tyre warm-

up and internal damage, leading to

tread separation and even to tyre

blow-out at high speeds.

Always inflate the spare tyre to the

pressure specified for full load.

Tyre pressure

Check the pressure of cold tyres at

least every 14 days and before any

long journey. Do not forget the spare

wheel. This also applies to vehicles

with tyre deflation detection system.

Incorrect tyre pressures will impair

safety, vehicle handling, comfort and

fuel economy and will increase tyre

wear.

Tyre pressures differ depending on

various options. For the correct tyre

pressure value, follow the procedure

below:

1. Identify the respective tyre.

2. Identify the engine identifier code.

Engine data 3 247.

The tyre pressure tables show all

possible tyre combinations 3 251.

For the tyres approved for your

vehicle, refer to the EEC Certificate of

Conformity provided with your vehicle

or other national registration

documents.

9 Warning

For specific tyres the

recommended tyre pressure as

shown in the tyre pressure table

may exceed the maximum tyre

pressure as indicated on the tyre.

Never exceed the maximum tyre

pressure as indicated on the tyre.

Temperature dependency

The tyre pressure depends on the

temperature of the tyre. During

driving, tyre temperature and

pressure increase. Tyre pressure

values provided on the tyre

system is inoperable when the ABS or

Electronic Stability Control has a

malfunction or a temporary spare

wheel is used. Once the tyre has been

refitted, check the tyre pressure with

cold tyres and initialise the system.

3. Initialise the system via the Info

Display 3 86.

4. Reset is confirmed by pop-up

indication.

Tyre deflation detection

system

After initialisation system

automatically calibrates to new tyre

pressures during driving. After longer

drive the system will adopt and

monitor new pressures.

The tyre deflation detection system

continually checks the rotation speed

of all four wheels and warns on low

tyre pressure condition once vehicle

is driving. This is achieved by

comparing tyre rolling circumference

with reference values and further

signals.

Caution

Deflation detection system warns

just about low tyre pressure

condition and does not replace

regular tyre maintenance by the

driver.

Always check tyre pressure with cold

tyres.

System has to be reinitialised when:

●

Tyre pressure has been changed

Load condition has been

changed

If a tyre loses pressure the control

indicator w illuminates and a warning

message is displayed in the Driver

Information Centre.

a rapid deflation. This is due to

required calculation time.

In this case reduce speed, avoid

sharp cornering and strong braking.

Stop at next safe opportunity and

check tyre pressure.

Vehicle care

223

If there is more wear at the front than

the rear, swap round front wheels and

rear wheels periodically. Ensure that

the direction of rotation of the wheels

remains the same.

Tyres age, even if they are not used.

We recommend tyre replacement

every six years.

Tread depth

Wheel covers

Check tread depth at regular

intervals.

Wheel covers and tyres that are

factory approved for the respective

vehicle and comply with all of the

relevant wheel and tyre combination

requirements must be used.

If the wheel covers and tyres used are

not factory approved, the tyres must

not have a wheel rim protection ridge.

For safety reasons, it is

recommended that the tread depth of

the tyres on one axle should not vary

by more than 2 mm.

Changing tyre and wheel

size

Wheel covers must not impair brake

cooling.

If tyres of a different size than those

fitted at the factory are used, it may be

necessary to reprogramme systems

and make other vehicle modifications.

9 Warning

Use of unsuitable tyres or wheel

covers could lead to sudden

pressure loss and thereby

accidents.

Have the label with tyre pressures

replaced.

9 Warning

Vehicles with steel wheel rims: When

using locking wheel nuts, do not

attach wheel covers.

Temporary spare wheel: Do not use

wheel covers.

The legally permissible minimum

tread depth (1.6 mm) has been

reached when the tread has worn

down as far as one of the tread wear

indicators (TWI). Their position is

indicated by markings on the

sidewall.

The use of unsuitable tyres or

wheels may lead to accidents and

will invalidate the vehicle

operating permit.

224

Vehicle care

Notice

Tyre damage exceeding 4 mm or that

is at tyre's sidewall cannot be repaired

with the tyre repair kit.

Depending on version, there are two

different tyre repair kits (Type A and

Type B).

Tyre chains

The use of tyre chains and the

maximum allowed speed is

regulated by country-specific

legislation.

9 Warning

Damage may lead to tyre blowout.

Do not drive faster than 50 mph.

Do not use for a lengthy period.

Steering and handling may be

affected.

When fitting the tyre chains follow the

instructions provided by the

manufacturer of the tyre chains.

After having fitted the tyre chains,

stop the vehicle after having driven a

short distance and make sure that the

tyre chains are correctly tightened.

Tyre chains are only permitted on the

front wheels.

Only use tryre chains designed to be

used with tyre type of the vehicle:

In the case of a flat tyre:

Apply the parking brake and engage

first gear, reverse gear or P.
