After changing of defective fuses,
close the fuse box cover and press
until it engages.
If the fuse box cover is not closed
correctly, malfunctions may occur.
Instrument panel fuse box
In left-hand drive vehicles, the fuse
box is behind the storage
compartment in the instrument panel.
Open compartment, compress the
locking tabs, fold compartment down and remove.
In right-hand drive vehicles, the fuse
box is located behind a cover in the
glovebox. Open the glovebox and
remove the cover.

Vehicle care257The use of commercially available
liquid tyre repair kits can impair the
function of the system. Factory-
approved repair kits can be used.
Operating electronic devices or being
close to facilities using similar wave
frequencies could disrupt the tyre
pressure monitoring system.
Each time the tyres are replaced tyre
pressure monitoring system sensors
must be dismounted and serviced.
For the screwed sensor replace valve core and sealing ring, for clipped
sensor replace complete valve stem.
Vehicle loading status Adjust tyre pressure to load condition
according tyre information label or
tyre pressure chart 3 295, and select
the appropriate setting in the Tyre
loading page under the Settings
menu in the Driver Information Centre 3 111 . This setting is the reference for
the tyre pressure warnings.
The menu Tyre loading only appears
if the vehicle is in a standstill and the parking brake is applied. On vehicles
with automatic transmission the
selector lever has to be in P.
Select:
● Light for comfort pressure up to
3 people.
● Eco for Eco pressure up to
3 people.
● Max for full loading.
Auto learn function
After changing wheels the vehicle
must be stationary for approx.
20 minutes, before the system
recalculates. The following relearn
process takes up to 10 minutes of
driving with a minimum speed of
20 km/h. In this case $ can be
displayed or pressure values can
swap in the Driver Information Centre.
If problems occur during the relearn
process, a warning message is
displayed in the Driver Information
Centre.
Tread depthCheck tread depth at regular
intervals.
Tyres should be replaced for safety
reasons at a tread depth of 2-3 mm
(4 mm for winter tyres).
For safety reasons, it is
recommended that the tread depth of
the tyres on one axle should not vary
by more than 2 mm.

3. Remove the electrical connectioncable and air hose from the
stowage compartments on the
underside of the compressor.
4. Screw the compressor air hose to
the connection on the sealant
bottle.
5. Fit the sealant bottle into the retainer on the compressor.
Set the compressor near the tyre
in such a way that the sealant
bottle is upright.
6. Unscrew valve cap from defective
tyre.
7. Screw the filler hose to the tyre valve.
8. The switch on the compressor must be set to J.
9. Connect the compressor plug to
the power outlet or cigarette
lighter socket.
To avoid discharging the battery,
we recommend running the
engine.
10. Set the rocker switch on the compressor to I. The tyre is filled
with sealant.
11. The compressor pressure gauge briefly indicates up to 6 bar whilstthe sealant bottle is emptying
(approx. 30 seconds). Then the
pressure starts to drop.
12. All of the sealant is pumped into the tyre. Then the tyre is inflated.

Lead connection order:1. Connect the red lead to the positive terminal of the booster
battery.
2. Connect the other end of the red lead to the positive terminal of the
discharged battery.
3. Connect the black lead to the negative terminal of the booster
battery.
4. Connect the other end of the black
lead to a vehicle grounding point,
such as the engine block or an
engine mounting bolt. Connect as
far away from the discharged
battery as possible, however at
least 60 cm.
Route the leads so that they cannot
catch on rotating parts in the engine
compartment.
To start the engine: 1. Start the engine of the vehicle providing the jump.
2. After 5 minutes, start the other engine. Start attempts should be
made for no longer than
15 seconds at an interval of
1 minute.
3. Allow both engines to idle for approx. 3 minutes with the leads
connected.
4. Switch on electrical consumers (e.g. headlights, heated rear
window) of the vehicle receiving
the jump start.
5. Reverse above sequence exactly when removing leads.Towing
Towing the vehicle
5-door Hatchback, 4-door Saloon,
Sports Tourer: disengage cap at
bottom and remove downwards.

in the slot at the lower edge of the cap. Release the cap by carefully moving
the screwdriver downwards. To
prevent damage, it is recommended
to place a cloth between the
screwdriver and the frame.OPC: insert screwdriver in the slot at

The towing eye is stowed with the vehicle tools 3 253.Screw in the towing eye as far as it will
go until it stops in a horizontal
position.
Attach a tow rope – or better still a tow
rod – to the towing eye.
The towing eye must only be used for
towing and not for recovering the

270Vehicle careCaution
Drive slowly. Do not drive jerkily.
Excessive tractive force can
damage the vehicle.
When the engine is not running,
considerably more force is needed to
brake and steer.
To prevent the entry of exhaust gases from the towing vehicle, switch on the
air recirculation and close the
windows.
Vehicles with manual transmission
and All-wheel drive: If the vehicle is
towed with all four wheels on the
ground then there are no technical
limitations for speed and distance. If
only one axle has been raised, the
maximum speed is 50 km/h. There is
no distance limitation.
Vehicles with automatic transmission and Front-wheel drive: The vehicle
must be towed facing forwards, not
faster than 80 km/h nor further than
100 km. In all other cases and when
the transmission is defective, the front axle must be raised off the ground.
Vehicles with automatic transmission
and All-wheel drive: The vehicle must
be towed facing forwards. If the
vehicle is towed with all four wheels
on the ground, the maximum speed is
50 km/h and for a maximum of
50 km. If the front axle has been
raised, the maximum speed is
50 km/h. There is no distance
limitation.
Seek the assistance of a workshop.
After towing, unscrew the towing eye.
