Te c h n i c a l D a t a
•
With compact temporary spare wheel.
•
When using the snow chains.
•
When driving in deep snow or on soft terrain.
•
When the vehicle is bogged-down, to free it by “rocking.”
The TCS should be switched on again afterwards as soon as possible.
WARNING
•
It must be remembered that TCS cann ot defy the laws of physics. This
should be kept in mind, particular ly on slippery and wet roads and when
towing a trailer.
•
Always adapt your driving style to suit the condition of the roads and
the traffic situation. Do not let the extra safety afforded by TCS tempt you
into taking any risks when driving, this can cause accidents.Caution
•
In order to ensure that TCS function correctly, all four wheels must be
fitted with the same tyres. Any differences in the rolling radius of the tyres can
cause the system to reduce engine power when this is not desired.
•
Modifications to the vehicle (e.g. to the engine, the brake system, running
gear or any components affecting the wh eels and tyres) could affect the effi-
ciency of the ABS and TCS.
XDS*
Driveshaft differentialWhen taking a bend, the driveshaft differential mechanism allows the outer
wheel to turn at a higher speed than the inner wheel. In this way, the wheel
which is turning faster (outer wheel) receives less drive torque than the inner
wheel. This may mean that in certain situations the torque provided to the inner wheel is too high, causing the wheels to spin. On the other hand, the
outer wheel receives a lower drive torque than it could transmit. This causes
an overall loss of lateral grip on the front shaft, resulting in understeering or
“lengthening” of the path.
The XDS system is able, using the ESP sensors and signals, to detect and
correct this effect.
The XDS, via the ESP, brakes the inner wheel thus counteracting the excess
drive torque in this wheel. This means that the path requested by the driver
is more precise,
The XDS system operates in combination with the ESP and is always active,
even when the traction control, TCS, is disconnected.
Electronic stabilisation programme (ESP)*General notes
The electronic stabilisation programme increases the
vehicle's stability on the road.The electronic stabilisation programme helps to reduce the danger of skid-
ding.
The electronic stabilisation programme (ESP) consists of
ABS, EDL, TCS and
Steering manoeuvre recommendations.
Electronic Stabilising Program (ESP)*
ESP reduces the danger of skidding by braking the wheels individually.
The system uses the steering wheel angle and road speed to calculate the
changes of direction desired by the driver, and constantly compares them
with the actual behaviour of the vehi cle. If the desired course is not being

Wheels and tyres
228Wheel bolts
Wheel bolts must be tightened to the correct torque.The design of wheel bolts is matched to the rims. If different wheel rims are
fitted, the correct wheel bolts with the right length and correctly shaped bolt
heads must be used. This ensures that wheels are fitted securely and that the
brake system functions correctly.
In certain circumstances, you may not use wheel bolts from a different car -
even if it is the same model ⇒page 200.
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 tight-
ening torque for steel and alloy wheels is 120 Nm.
WARNING
If the wheel bolts are not tightened correctly, the wheel could become
loose while driving. Risk of accident.•
The wheel bolts must be clean and turn easily. Never apply grease or oil
to them.
•
Use only wheel bolts which belong to the wheel.
•
If the torque of the wheel bolts is to o low, they could loosen whilst the
vehicle is in motion. Risk of accident! If the tightening torque is too high,
the wheel bolts and threads can be damaged.Caution
The prescribed torque for wheel bolts for steel and alloy wheels is 120 Nm.
Winter tyres
Winter tyres will improve the vehicles handling on snow and
ice.In winter conditions winter tyres will considerably improve the vehicles
handling. The design of summer tyres (width, rubber compound, tread
pattern) gives less grip on ice and snow.
Winter tyres must be inflated to a pressure 0.2 bar higher than the pressures
specified for summer tyres (see sticker on tank flap).
Winter tyres must be fitted on all four wheels.
Information on permitted winter tyre sizes can be found in the vehicle's regis-
tration documents. 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 227, “New tyres and wheels” determines the
following speed limits for winter tyres: ⇒
Q max. 160 km/h
S max. 180 km/h
T max. 190 km/h
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 227, “New tyres and wheels”.

General notes on the technical data
262To w i n g a t r a i l e rTrailer weightsTrailer weights
The trailer weights and drawbar loads approved are selected in intensive
trials according to precisely defined criteria. The approved trailer weights are
valid for vehicles in the EU for maximum speeds of 80 km/h (in certain
circumstances up to 100 km/h). The figu res may be different in other coun-
tries. All data in the official vehicl e documents take precedence over these
data ⇒ .
Drawbar load
The maximum permitted weight exerted by the trailer drawbar 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
approaching 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 loa d cannot be met (e.g. with small,
empty and light-weight single axle trailers or tandem axle trailers with an axle
base of less than 1 metre), at least 4% of the actual trailer weight is a legal
stipulation for a drawbar load.
WARNING
•
For safety reasons, do not exceed the 80 km/h limit. This is also valid in
countries where higher speeds are permitted.
•
Never exceed the maximum trailer weights or the draw bar loading. 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.
WheelsTyre pressure, snow chains, wheel boltsTyre pressures
The sticker with the tyre pressure values can be found on the inside of the
tank flap. The tyre pressure values given there are for cold tyres. The slightly
raised pressures of warm tyres must not be reduced ⇒.
Snow chains
Snow chains may be fitted only to the front wheels.
Consult the chapter “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 tight-
ening torque for steel and alloy wheels is 120 Nm.
WARNING
•
Check the tyre pressure at least once per month. Checking tyre pressure
value 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 torque of the wheel bolts is too low, they could loosen while the
vehicle is in motion. Risk of accident! If the tightening torque is too high,
the wheel bolts and threads can be damaged.Note
We recommend that you ask your Authorised Service Centre for information
about appropriate wheel, tyre and snow chain size.
