When the TCS is off, the warning lamp is lit. The TCS should normally
be left on. Only in exceptional circumstances, when the slipping of the wheels
is required, should it be disconnected, for example
•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 as soon as possible.WARNING
•It must be remembered that TCS cannot defy the laws of physics. This
should be kept in mind, particularly 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 wheels 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
that is turning faster (outer wheel) receives less drive torque than the inner
wheel. This may mean that in certain situations the torque delivered to the
inner wheel is too high, causing the wheels to spin. On the other hand, the
outer wheel is receiving a lower drive torque than it could transmit. This
causes an overall loss of lateral grip on the front axle, resulting in understeer
or “lengthening” of the trajectory.
By using the ESP sensors and signals, the XDS system is able to detect and
correct this effect.
Through the ESP, the XDS brakes the inner wheel, thereby counteracting the
excess drive torque in this wheel. This means that the driver’s desired trajec-
tory is much more precise,
The XDS system operates in combination with the ESP and is always active,
even when the traction control, TCS, is disconnected.Electronic Stability Programme (ESP)*General notes
The Electronic Stability Programme increases the vehicle’s
stability on the road.The Electronic Stability Programme helps reduce the danger of skidding.
The Electronic Stability Programme (ESP) consists of ABS, EDL, TCS and
Steering manoeuvre recommendations.

Wheel 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 should not use wheel bolts from a different
vehicle, even if it is the same model ⇒page 212.
After the wheels have been changed, the tightening torque of the wheel bolts
s ho uld b e ch ecke d as so on as possi ble wi th a to rq ue wre nch. ⇒ 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 too 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 tightening 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 vehicle’s
handling. The design of summer tyre s (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 242, “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 242, “New tyres and wheels”.

Description of specifications
276If 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
wheelbase of less than 1 metre), at least 4% of the actual trailer weight is a
legal stipulation for a drawbar load.
WARNING
•For safet y reas ons , d o not excee d the 8 0 k m/h limit . Th is is als o valid in
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.

ening 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 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
