CAUTIONEnsure that battery acid does not come into contact with the bodywork –
There is a risk of damage to the vehicle.
Note
■ We recommend having all work on the vehicle battery carried out by a spe-
cialist garage.■
You should replace batteries older than 5 years.
Check condition
Fig. 296
Vehicle battery: Open the cover / acid level indicator
Read and observe
and on page 258 first.
The battery condition is checked regularly by a specialist garage as part of the
inspection service.
Check the acid level
For car batteries with acid level indicator, acidity can be checked on the basis
of a colour display. In vehicle batteries with the label “AGM” there is no acid
level examination.
Depending on the equipment, the vehicle battery may be provided with a cov-
er, this can be opened in the direction of arrow » Fig. 296 -
.
Air bubbles can influence the colour of the indicator. For this reason carefully
tap on the indicator before carrying out the check » Fig. 296 -
.
Black colour – electrolyte level is correct.
Colourless or light yellow colour – electrolyte level too low, the battery must be replaced.
Battery discharge
If frequent short journeys are made, the vehicle battery does not recharge suf- ficiently.
The battery capacity decreases at low temperatures.
If the vehicle is not used for longer than 3 to 4 weeks, then disconnect the
negative terminal
of the battery or charge the battery constantly with a very
low charging current.
Charging
Read and observe
and on page 258 first.
Only charge the battery when the ignition and all consumers are switched off.
Refer to the instructions of the charger manufacturer.
Charging
›
For vehicles with the START-STOP system or auxiliary heater
, connect the
-terminal of the charger on the battery’s -pole,
the -terminal of the
charger to the ground point of the engine » page 272.
›
For vehicles without the START-STOPsystem or auxiliary heating, connect
the charger terminals to the corresponding battery poles ( to
,
to
).
›
Plug the mains cable of the charger into the power socket and switch on the
device.
›
After charging has been successful: Switch off the charger and remove the
mains cable from the power socket.
›
Disconnect the terminals of the charger from the vehicle battery.
A charging current of 0.1 multiple of the total vehicle battery capacity (or low-
er) must be used until full charging is achieved.
WARNING■ When charging the vehicle battery, hydrogen is released - risk of explo-
sion. An explosion can be caused through sparking while unclamping or
loosening the cable plug.■
So-called “quick-charging” of the vehicle battery is dangerous and re-
quires a special charger and specialist knowledge. Therefore, have“Quick
loading” carried out by a specialist garage.
259Inspecting and replenishing
Preparing to use the breakdown kitRead and observe
on page 270 first.
For safety's sake, the following instructions must be observed before
undertaking a wheel repair on a road.
›
Park the vehicle as far as possible away from the traffic flow - choose a place
with a flat and firm surface.
›
Switch off the engine.
›
For vehicles with manual transmission select 1. gear.
›
For vehicles with automatic transmission , place the selector lever in the P
position.
›
Firmly apply the handbrake.
›
Switch on the hazard warning lights and set up the warning triangle at the
prescribed distance.
›
Have all the occupants get out . While the repair is being carried out, the pas-
sengers should not stand on the road (instead they should remain behind a
crash barrier, for instance).
›
Uncouple any trailers.
Sealing and inflating tyres
Read and observe
on page 270 first.
Sealing
›
Unscrew the valve cap from the damaged tyre.
›
Insert the valve remover
2
» Fig. 309 on page 270 on the valve insert, so that
the valve insert fits into the slot of the valve remover.
›
Unscrew the valve insert and place it on a clean base (rag, paper etc.).
›
Forcefully shake bottle
10
several times.
›
Firmly screw the inflation hose
3
onto the tyre inflater bottle
10
. The film on
the bottle cap is pierced.
›
Remove the plug from the inflation hose
3
and insert the bottle onto the
tyre valve.
›
Hold the bottle
10
with the bottom facing upwards and fill all of the sealing
agent from the tyre inflator bottle into the tyre.
›
Remove the filler plug from the tyre valve.
›
Screw in the valve insert with the valve remover
2
.
Inflating
›
Screw the tyre inflation hose
7
» Fig. 309 on page 270 firmly onto the tyre
valve.
› For vehicles with
manual transmission , set the lever in the neutral position.›On vehicles with automatic transmission , place the selector lever in the P
position.›
Start the engine.
›
Plug the connector
6
into 12 volt socket » page 90.
›
Switch on the air compressor with the ON and OFF switch
9
.
›
Once tyre inflation pressure of 2.0-2.5 bar has been reached, turn off the air
compressor. Maximum run time of 6 minutes » .
›
If you cannot reach an air pressure of 2.0 - 2.5 bar, unscrew the tyre inflation
hose
7
from the tyre valve.
›
Drive the vehicle 10 metres forwards or backwards to allow the sealing agent
to “distribute” in the tyre.
›
Firmly screw the tyre inflation hose
7
back onto the tyre valve and repeat
the inflation process.
›
Stick the corresponding sticker
1
on the dashboard in the driver's field of
view.
At a tyre inflation pressure of 2.0–2.5 bar, the journey can be continued at a
maximum speed of 80 km/h or 50 mph.
WARNING■ If the tire does not inflate at least. 2.0 bar, the damage is too great. The
sealing agent cannot be used to seal the tyre. Do not drive the vehicle.
Seek help from a specialist garage.■
The tyre inflation hose and air compressor may get hot as the tyre is be-
ing inflated – risk of burning.
CAUTION
Switch off the air compressor if it has been running for as much as 6 minutes –
risk of damage to the compressor! Allow the air compressor to cool a few mi-
nutes before switching it on again.
Information on driving with repaired tyres
Read and observe
on page 270 first.
The inflation pressure of the repaired tyre must be checked after driving for 10minutes.
If the tyre inflation pressure is 1.3 bar or less
›
You cannot properly seal the tyre using the breakdown kit.
Stop driving!
Seek help from a specialist garage.

Individual electrical circuits are protected by fuses. A blown fuse is recognisa-
ble from the melted-through metal strip » Fig. 324.
WARNINGAlways read and observe the warnings before completing any work in the
engine compartment » page 252.
CAUTION
■
Replace the faulty fuse with a new one of the same amperage.■If a newly inserted fuse again blows after a short time, then seek assistance
from a specialist garage.■
“Do not repair” the fuses and do not replace them with stronger fuses -
There is a risk of fire and damage to another electrical system.
Note
■ We recommend always carrying replacement fuses in the vehicle.■There can be several power consuming devices for one fuse. Multiple fuses
may exist for a single power consuming device.278Do-it-yourself

We recommend having bulbs replaced by a specialist garage or seeking other
expert help in the event of any uncertainties.
▶ Switch off the ignition and all of the lights before replacing a bulb.
▶ Faulty bulbs must only be replaced with the same type of bulbs. The designa-
tion is located on the light socket or the glass bulb.
We recommend having the headlight settings checked by a specialist garage after replacing a bulb in the low, high or fog beam.
In the case of failure of a Xenon gas discharge bulb or an LED diode, visit a
specialist garage.WARNING■ Always read and observe the warnings before completing any work in the
engine compartment » page 252.■
Accidents can be caused if the road in front of the vehicle is not suffi-
ciently illuminated and the vehicle cannot or can only be seen with difficul-
ty by other road users.
■
Bulbs H7 H8 and H15 are pressurised and may burst when changing the
bulb - risk of injury! We therefore recommended wearing gloves and safety
glasses when changing a bulb.
■
Do not carry out any work on the Xenon gas discharge lamps - risk of
death!
CAUTION
Do not take hold of the glass bulb with naked fingers (even the smallest
amount of dirt reduces the working life of the light bulb). Use a clean cloth,
napkin, or similar.
Note
■ This Owner's Manual only describes the replacement of bulbs where it is pos-
sible to replace the bulbs on your own without any complications arising. Other
bulbs must be replaced by a specialist garage.■
We recommend that a box of replacement bulbs always be carried in the ve-
hicle.
