Wheels
... Check that the snow chains are correctly seated
after driving for a few yards; follow the instruc
tions given by the manufacturer.
... Keep your speed below 50 km/h. Please ob-
serve the applicable local regulations.
For technical reasons snow chains may only be
used on tyres with certain wheel rim/tyre combi
nations.
Rim size
Rim offset

7Jx17

You must remove the snow chains on roads which
are free of snow; otherwise the vehicle handling
may be impaired and the tyres may be damaged.
A
WARNING
Unsuitable or incorrectly mounted snow
chains can cause you to lose control of the ve
hicle - risk of accident!
CD
CAUTION
- Snow chains can damage the rim/hubcap* if
they make direct contact with it. Remove
the hubcaps* beforehand. Use snow chains
which have a protective coating.
- If you use snow chains with links that pro
trude more than 13.5 mm, this could cause
severe damage to the wheel housings and
other parts of the vehicle.

Low-profile tyres
Applies to: vehicles with low-profile tyres
Your vehicle is fitted with low-profile tyres* as
standard equipment. Low-profile tyres have a
lower sidewall and provide a wider tread surface
and rim diameter than other wheel/tyre combi
nations. This makes the car's handling more
agile. However, the ride may be less comfortable
on poor-quality roads and tracks, and rolling
noise may be louder.

Low-profile tyres can be damaged more quickly
than standard tyres, for example by heavy jolts,
potholes, manhole covers, speed humps and
kerbs. It is therefore particularly important to
ensure that they are inflated to the correct pres
sure
c:>page 256.
Drive with particular care on poor-quality roads
to ensure that you do not damage the rims and
tyres.
Make sure to check your wheels regularly (every
3,000 km) for damage such as blisters/tears on
the tyre sidewalls or deformations/cracks on the
rims.
After a heavy jolt, or if any damage occurs, you
should have the rims and tyres checked and if
necessary replaced by a qualified workshop.
Tyre wear occurs more quickly on low-profile
tyres than on standard tyres.
Summer tyres are not suitable for cold condi
tions, snow or ice. Use winter or all-season tyres
when driving in these conditions

Tyre pressure Loss
indicator
Tyre pressure loss indicator in instrument
cluster
Applies to: vehicles with tyre pressure loss indicator
The tyre pressure Loss indicator in the instrument
cluster informs the driver if the tyre pressure is
too Low or a system malfunction has occurred.
The tyre pressure loss indicator makes use of the
ABS sensors to compare the rolling circumfer
ence and the vibration of the tyres. If changes in
the inflation pressure are detected on one or
more tyres, the driver is alerted by an indicator
lamp
[tE
and a message on the infotainment dis
play. If only one tyre is affected, the display will
indicate its position.
Each time you change a tyre, change the wheels
round or change the tyre pressures on your vehi
cle (e.g. when switching from partial load to full
load and vice-versa), you must store the new tyre
pressures on the infotainment system
