Advice
Tyre pressure
The c orr
ect ty
re pressure is especially impor-
tant at high speeds. The pressure should
therefore be checked at least once a month
and before starting a journey.
Depending on the vehicle, tyre pressure can
be adjusted to medium load to improve driv-
ing comfort (“comfort” tyre pressure). When
driving with comfort tyre pressure fuel con-
sumption may increase slightly. WARNING
A tyre can easily burst if the pressure is too
low, c au

sing an accident!
● At continuously high speeds, a tyre with in-
sufficient pr
essure flexes more. In this way it
becomes too hot, and this can cause tread
separation and tyre blow-out. Always observe
the recommended tyre pressures.
● If the tyre pressure is too low or too high,
the tyres
will wear prematurely and the vehi-
cle will not handle well. Risk of accident! For the sake of the environment
Under-inflated tyres will increase fuel con-
sumption. Tyre useful life
Fig. 189
Tyre tread wear indicators. Fig. 190
Diagram for changing wheels The useful life of tyres is dependent on tyre
pr
e
ss

ure, driving style and fitting.
Wear indicators
The original tyres on your vehicle have
1.6 mm high “tread wear indicators”
››› Fig. 189, running across the tread. De- pending on the make, there will be 6 to 8 of
them evenly s

paced around the tyre. Mark-
ings on the tyre sidewall (for instance the let-
ters “TWI” or other symbols) indicate the po-
sitions of the tread wear indicators. The mini-
mum tread depth required by law is 1.6 mm
(measured in the tread grooves next to the
tread wear indicators). Worn tyres must be re-
placed. Different figures may apply in export
countries ››› .
T y
re pr

essure
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 213.
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 advisable to change
them around as shown ››› Fig. 190. The use-
ful life of all the tyres will then be about the
same time.
Wheel balance
The wheels on new vehicles are balanced.
However, various factors encountered in nor-
mal driving can cause them to become unbal-
anced, which results in steering vibration.

Wheels
● The wheel s
of one ax
le are under more
pressure (for example, driving with a trailer or
on steep slopes).
● The vehicle is fitted with snow chains.
● The temporary spare wheel is fitted.
● The wheel on one axle is changed.
Tyre pr
essure adjustment
On adjusting tyre pressure or changing one
or more wheels, the ››› Fig. 191 button must
be kept pressed down, with the ignition on,
until an acoustic signal is heard.
Store the new tyre pressure in the Easy Con-
nect system with the button  and the func-

age 24.
If

the wheels are under excessive load (for ex-
ample, driving with a trailer or heavy load),
the tyre pressure must be increased to the
recommended value for a full load (see the
sticker on the inside of the fuel flap). If the
tyre monitor system button is pressed down,
the new tyre pressures are confirmed.
The tyre pressure control lamp  lights up
If the tyre pressure of a wheel is much lower
than the value set by the driver, then the tyre
pressure control lamp ››› will light up.
WARNING
● When the tyre pr e

ssure control lamp lights
up, reduce speed immediately and avoid any sudden turning or braking manoeuvre. Stop
when poss
ib

le, and check the tyre pressure
and status.
● The driver is responsible for maintaining
correct ty
re pressures. For this reason, tyre
pressure must be regularly checked.
● Under certain circumstances (e.g. when
driving in a spor
ty manner, in winter condi-
tions or on a dirt track) the tyre control lamp
may light up belatedly or may function incor-
rectly. Note
If the battery is disconnected, the yellow
warning l amp

 lights up after turning the
ignition on. This should turn off after a brief
journey. Winter service
W int
er ty r

es In winter conditions winter tyres will consid-
er
ab
ly impr

ove the vehicle's handling. The
design of summer tyres (width, rubber com-
pound, tread pattern) gives less grip on ice
and snow.
Winter tyres must be inflated to a pressure of
0.2 bar (2.9 psi/20 kPa) higher than the pres-
sures 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 registration
documentation. Use only radial winter tyres.
All tyre sizes listed in the vehicle documenta-
tion 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 215, New
tyres and wheels determines the following
speed limits for winter tyres: ››› max. 160 km/h (99 mph)
m
ax. 180 km/h (112 mph)
m ax. 190 km/h (118 mph)
m ax. 210 km/h (130 mph)
In some c

ountries, 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 unnecessa-
rily 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 215, New
tyres and wheels . »

Drawbar loads
The maximum permitt ed dr
awb
ar load on the
ball joint of the towing bracket must not ex-
ceed 75 kg.
In the interest of road safety, we recommend
that you always tow approaching the maxi-
mum drawbar load. The response of the trail-
er 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 wheelbase of less than 1
metre), a minimum of 4% of the actual trailer
weight is legally required for the drawbar
load. WARNING
● For saf ety

reasons, you should not drive at
speeds above 80 km/h (50 mph) when towing
a trailer. This also applies in countries where
higher speeds are permitted.
● Never exceed the maximum trailer weights
or the drawbar lo
ad. If the permissible axle
load or the permissible total weight is excee-
ded, the driving characteristics of the vehicle
may change, leading to accidents, injuries
and damage to the vehicle. Wheels

The stick
er w

ith 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 ››› .
The pres s

ure for winter tyres is 0.2 bar higher
than that of summer tyres (2.9 psi / 20 kPa).
Snow chains
Snow chains may be fitted only to the front
wheels, and only for the following tyres:
175/70R14
185/60R15Chains with links not exceeding 15 mm
(including the chain closure)
215/45R16Chains with links not exceeding 9 mm
(including the chain closure)
215/40R17Chains with links not exceeding 7 mm
(including the chain closure) Wheel bolts
Af
t
er the wheel s

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 al lo
y wheel

s is 120 Nm. WARNING
● Check the ty r

e pressure at least once per
month. Checking the tyre pressure is very im-
portant. 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 lo
w, they could loosen while the vehi-
cle is in motion. Risk of accident! If the tight-
ening torque is too high, the wheel bolts and
threads can be damaged. Note
We recommend that you ask your Technical
Servic e f

or information about appropriate
wheel, tyre and snow chain size. 221
