Driving on unpaved roads for long periods, or a sporty driving style, can temporarily
deactivate the Tyre Pressure Loss Indicator. The indicator lamp shows the malfunction, but
disappears if the road conditions or driving style change.
Troubleshooting for the Tyre Pressure Monitoring System
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Lit up
•Do not drive on!
•Check all wheels for exterior damage or foreign bodies that have entered the tyres.
•Check the tyre pressure for all tyres ⇒ Tyre pressure.
•Change the wheel or drive at a low speed to the nearest qualified workshop.
•Check and adjust the tyre pressure for all tyres ⇒ Tyre pressure.
•Change the wheel or drive at a low speed to the nearest qualified workshop.
•Avoid long journeys and high speeds as long as the warning is displayed.
•Check ⇒ Tyre pressure and adjust the tyre pressure for all tyres.
Flashes
•Switch off or avoid any disruptive sources, e.g. two-way radios, remote controls or children's
toys.
•Switch the ignition off and then back on again. If the problem persists, seek expert assistance.
Differing tyre pressures or tyre pressures that are too low can cause tyre damage, tyre
failure, loss of vehicle control, accidents, serious injury and death.
•If the indicator lamp lights up, stop the vehicle as soon as possible and check all
the tyres ⇒ Useful information about wheels and tyres.
•Different tyre pressures or tyre pressures that are too low can increase wear on the
tyres, reduce vehicle stability and increase the braking distance.
•Differing tyre pressures or tyre pressures that are too low can cause sudden tyre
failure and lead to a tyre bursting and the loss of control over the vehicle.
•The driver is responsible for the correct tyre pressure of all tyres on the vehicle. The
recommended tyre pressure can be found on a sticker ⇒ Tyre pressure.
•The tyre monitoring system cannot function correctly until all cold tyres have the
correct tyre pressure.
•The pressure in all tyres must always be appropriate to the vehicle load ⇒ Tyre
pressure.
•Always inflate all tyres to the correct tyre pressure before every journey ⇒ Tyre
pressure.
•If the vehicle is driven with insufficient tyre pressure, this results in greater tyre flexing.
This could warm up the tyre to such an extent that the tread may separate and the tyre
could burst. This could cause the driver to lose control of the vehicle.
•High speeds and overloading of the vehicle may cause the tyres to heat up to such an
extent that the tyre bursts, leading you to lose control of the vehicle.
•If the tyre pressure is too low or too high, the tyres will wear prematurely and the
vehicle will not handle well.
•If the tyre is not flat and it is not necessary to change the wheel immediately, drive at
low speed to the nearest qualified workshop and check and correct the tyre pressure
⇒ Useful information about wheels and tyres.
WARNING
Removing the spare wheel
•Open the boot lid.
•Raise or fold forward the luggage compartment floor ⇒ Boot lid.
•Pull the wedge of the locating element ⇒ Fig. 239① upwards and out.
•Unscrew the handwheel in the middle of the spare wheel ② anticlockwise fully and remove the
spare wheel.
Storing the removed wheel
•Open the boot lid and raise the luggage compartment floor or fold it forwards.
•Place the removed wheel into the spare wheel well with the rim facing downwards so that the
central hole in the rim positioned exactly above the threaded pin.
•Screw the handwheel ⇒ Fig. 239② clockwise onto the threaded pin until the replaced wheel is
firmly secured.
•Insert the locating element wedge ① into the slot of the threaded pin so that the handwheel can
no longer be turned.
If the spare wheel tyre is not the same as the tyres that are mounted on
the vehicle
If the spare wheel tyre differs from the other tyres on the vehicle, the spare wheel must be used
only in the event of a tyre failure and for a short time ⇒.
Follow these guidelines:
•Do not drive faster than 80 km/h (50 mphyf .
•Avoid full acceleration, sudden braking and fast driving through bends in the road.
•Do not use snow chains on the temporary spare wheel ⇒ Snow chains.
•The tyre pressure must be checked as soon as possible after fitting the spare wheel or
temporary spare wheel ⇒ Tyre pressure.
Tyre lettering and tyre type
Incorrect use of the spare wheel or temporary spare wheel can lead to a loss of control of
the vehicle, to collisions or other accidents and cause serious injuries.
•Never use a spare wheel or temporary spare wheel if it is damaged or worn down to the
tread wear indicators.
•Some vehicles may be equipped with a temporary spare wheel instead of a spare
wheel. The temporary spare wheel can be recognised by a sticker and the text 80 km/h
or 50 mph. This is the maximum speed at which you are permitted to drive with this
tyre. The sticker must remain in place throughout the wheel's service life.
•Never drive faster than 80 km/h (50 mphyf ' R Q R W D F F H O H U D W H T X L F N O \ E U D N H V X G G H Q O \ R U
drive at high speed through bends.
•Never drive further than 200 km with a temporary spare wheel if it is fitted to the drive
axle.
•The temporary spare wheel should be exchanged for a normal wheel as soon as
possible. The temporary spare wheel is designed for a short period of use only.
•The temporary spare wheel must always be secured firmly with the wheel bolts
supplied by the factory.
•Never drive using more than one spare wheel that is a different size than the original
tyres.
•After fitting the temporary spare wheel, the tyre pressure must be checked as soon as
possible ⇒ Tyre pressure.
•Snow chains must not be used on the temporary spare wheel.
•Do not fit a temporary spare wheel to the rear axle when towing a trailer ⇒.
WARNING
The spare wheel is not fitted with a tyre pressure sensor. If the spare wheel is used with
tyre pressure sensor, the tyre monitoring system indicator lamp will flash in the instrument
cluster display after approximately ten minutes ⇒ Tyre monitoring systems.
