1. Reduce your speed and stop the car care-
fully. Avoid violent or sudden braking and

3. Change the wheel with the damaged tyre,
see Wheel-changing on page 231.
Run-flat tyres*
1. Carefully reduce your speed to below
80 km/h, approx. 50 mph. Avoid violent or
sudden braking and steering manoeuvres
and do not exceed a speed of 80 km/h,
approx. 50 mph.
If the vehicle is not provided with run-
flat tyres, see page 221, then the
vehicle cannot drive further, otherwise if
you continue driving with a puncture it can
lead to severe accidents.<
2. As soon as you get an opportunity, check
tyre pressure in all four tyres.
If the tyre pressure in all four tyres is
correct, the Run Flat Indicator may
not have been initialised. Initialise the sys-
tem.<
3. If the tyre is completely deflated or if there is
clear evidence of damage to the tyre, you
can estimate how far you will be able to
drive using the following guidelines:
> With low loads:
1 to 2 persons, without luggage:
Approx. 250 km, approx. 150 miles.
> With moderate loads:
2 persons, luggage area full, or 4 per-
sons without luggage:
Approx. 150 km, approx. 90 miles.
> With full load:
4 or more persons, luggage area full:
Approx. 50 km, approx. 30 miles.
Drive with caution and do not exceed a
speed of 80 km/h, approx. 50 mph. If
there is a loss of tyre pressure, the vehicle's
handling properties will change. These include
reduced track stability during braking, longer
Service.<
