If no tyre damage can be identified, contact a
Service Partner of the manufacturer or an‐
other qualified Service Partner or a specialist
workshop.
2. Repair the flat tyre, for example using a flat
tyre kit or by changing the wheel.
The use of sealant, for example a flat tyre kit, can
damage the TPM wheel electronics. Have the
electronics replaced at the next opportunity.
Run-flat tyres
Safety notes
WARNING
A run-flat tyre which has low tyre inflation pres‐
sure or no tyre inflation pressure at all will
change the vehicle's handling characteristics,
for example there may be reduced directional
stability when braking, longer braking distances
and different self-steering characteristics.
There is a danger of accidents. Drive with care
and do not exceed a speed of 80 km/h,
50 mph.
Maximum speed
If a tyre is damaged you can continue your jour‐
ney, but do not exceed a maximum speed of
80 km/h, 50 mph.
Continuing a journey with a flat tyre
Note the following if you continue a journey with
a flat tyre:
1. Avoid violent or sudden braking and steering
manoeuvres.
2. Do not exceed a speed of 80 km/h, 50 mph.
3. As soon as there is an opportunity, check the
tyre inflation pressure in all four tyres.
In the case of tyres with special approval: if all
four tyres are inflated to the correct tyre infla‐
tion pressures, the Tyre Pressure Monitor
might not have been reset. Perform a reset.
Possible driving distance with a deflated
tyre
The possible driving distance varies depending
on the load and stresses the vehicle is subjected
to, for example speed, road properties, outside
temperature. The driving distance can be shorter
or, if the driving style is more careful, longer.
If the vehicle is moderately loaded and used un‐
der favourable conditions, it is possible to travel
up to 80 km, 50 miles.
Driving properties with damaged tyres
On a journey with damaged tyres, handling char‐
acteristics change and may result in the following
situations, for example:
▷ The vehicle losing traction more quickly.
▷ Longer braking distances.
▷ Changed self-steering characteristics.
Adapt your driving style. Avoid abrupt steering or
driving over obstacles, for example kerbs or pot‐
holes.
Final tyre failure
Vibration or loud noises during the journey may
be an indication that the tyre has finally failed.
Reduce your speed and stop the vehicle. Parts of
the tyre could detach, which could lead to an ac‐
cident.
Do not continue driving, but contact a Service
Partner of the manufacturer or another qualified
Service Partner or a specialist workshop.
System limits
Temperature
The tyre inflation pressure depends on the tem‐
perature of the tyre.
The tyre inflation pressure increases as the tyre
temperature increases, for example during driv‐
ing or due to exposure to sunlight.
Tyre inflation pressure decreases if the tyre tem‐
perature drops.
