A highly explosive mixture of gases is released when the bat-
tery is under charge.
Keep children away from acid and batteries!
WARNING
Always be aware of the danger of injury and chemical burns as well as
the risk of accident or fire when working on the battery and the electrical
system:
● Wear eye protection. Protect your eyes, skin and clothing from acid
and particles containing lead.
● Battery acid is extremely corrosive. Wear protective gloves and eye
protection. Do not tilt the batteries. This could spill acid through the
vents. Rinse battery acid from eyes immediately for several minutes with
clear water. Then seek medical care immediately. Neutralise any acid
splashes on the skin or clothing with a soapy solution, and rinse off with
plenty of water. If acid is swallowed by mistake, consult a doctor immedi-
ately.
● Fires, sparks, open flames and smoking are prohibited. When han-
dling cables and electrical equipment, avoid causing sparks and electro-
static charge. Never short the battery terminals. High-energy sparks can
cause injury.
● A highly explosive mixture of gases is released when the battery is
under charge. The batteries should be charged in a well-ventilated room
only.
● Keep children away from acid and batteries.
● Before working on the electrical system, you must switch off the en-
gine, the ignition and all consumers. The negative cable on the battery
must be disconnected. When a light bulb is changed, you need only
switch off the light.
WARNING (Continued)
● Deactivate the anti-theft alarm by unlocking the vehicle before you
disconnect the battery! The alarm will otherwise be triggered.
● When disconnecting the battery from the vehicle on-board network,
disconnect first the negative cable and then the positive cable.
● Switch off all electrical consumers before reconnecting the battery.
Reconnect first the positive cable and then the negative cable. Never re-
verse the polarity of the connections. This could cause an electrical fire.
● Never charge a frozen battery, or one which has thawed. This could
result in explosions and chemical burns. Always replace a battery which
has frozen. A flat battery can freeze at temperatures around 0 °C.
● Ensure that the vent hose is always connected to the battery.
● Never use a defective battery. This could cause an explosion. Replace
a damaged battery immediately.
CAUTION
● Never disconnect the battery if the ignition is switched on or if the en-
gine is running. This could damage the electrical system or electronic com-
ponents.
● Do not expose the battery to direct sunlight over a long period of time,
as the intense ultraviolet radiation can damage the battery housing.
● If the vehicle is left standing in cold conditions for a long period, protect
the battery from freezing. If it freezes it will be damaged. 
Charging the battery
A fully-charged battery is important for reliable starting. – Note the warnings ⇒

2. The tyre pressures should only be checked when the tyres are
cold. The slightly raised pressures of warm tyres must not be re-
duced.
3. Adjust the tyre pressure to the load you are carrying.
Tyre pressure
The correct tyre pressure is especially important at high speeds. The pres-
sure should therefore be checked at least once a month and before starting
a journey.
The sticker with the tyre pressure values can be found on the inside of the
fuel tank flap. The tyre pressure values given are for cold tyres. Do not re-
duce the slightly raised pressures of warm tyres ⇒ 
.
WARNING
● Check the tyre pressure at least once per month. Checking the tyre
pressure is very important. If the tyre pressure is too high or too low,
there is an increased danger of accidents - particularly at high speeds.
● A tyre can easily burst if the pressure is too low, causing an accident!
● At continuously high speeds, a tyre with insufficient pressure flexes
more. In this way it becomes too hot, and this can cause tread separation
and tyre blow-out. Always observe the recommended tyre pressures.
● If the tyre pressure is too low or too high, the tyres will wear prema-
turely and the vehicle will not handle well. Risk of accident!
For the sake of the environment
Under-inflated tyres will increase fuel consumption. Tyre pressure monitoring*
The tyre pressure monitoring system constantly checks the
pressure of the tyres.
The system warns the driver in the event of a loss of pressure by means of
symbols and messages in the instrument panel display.
Note that tyre pressure also depends on tyre temperature. Tyre pressure in-
creases about 0.1 bar for each 10 °C in tyre temperature increase. The tyre
heats up while the vehicle is being driven and the tyre pressure will rise ac-
cordingly. For this reason, you should only adjust the tyre pressures when
they are cold (i.e. approximately at ambient temperature).
To ensure that the tyre pressure monitoring system works reliably, you
should check and, if necessary, adjust the tyre pressures at regular intervals
and store the correct pressures (reference values) in the system.
A tyre pressure information label is attached to the inside of the fuel tank
flap.
WARNING
● Never adjust tyre pressure when the tyres are hot. This may damage
or even burst the tyres. Risk of accident!
● An insufficiently inflated tyre flexes a lot more at high speeds and
causes significant heating of the tyre. Under these conditions, the tyre
bead may be released or the tyre may burst. Risk of accident!
For the sake of the environment
Under-inflated tyres lead to increased fuel consumption and tyre wear. 

Wheels and tyres
Significant tyre pressure loss
The tyre symbol  is displayed and indicates that the tyre pressure
of at least one tyre is insufficient.
– Stop the vehicle.
– Switch the ignition off.
– Check the tyre(s).
– Change the wheel if necessary. 
Tyre pressure monitoring (RKA+)*
The tyre pressure monitor display on the instrument panel
indicates if the pressure is too low.
Fig. 190 Detailed view of
the centre console: But-
ton for the tyre pressure
monitoring system The tyre pressure monitoring system makes use of the ABS sensors to com-
pare the rolling circumference and the frequency characteristics of the
wheels. If the rolling circumference or frequency characteristic changes on
one or more wheels, the tyre pressure warning lamp  will light up. The
fault will also be indicated by a warning buzzer. The position of the affected
tyre will also be shown (if only one tyre is affected) on the centre display of
the instrument panel.
The rolling circumference and frequency characteristics can change if:
●
the tyre pressure is too low.
● the tyre has suffered structural damage.
● the wheels or the inflation pressures have been changed without initial-
ising the system (see Adjusting the tyre pressure settings).
● there is a greater load on the wheels of one axle (e.g. if you are carrying
more passengers or luggage).
● the road surface under the left wheels is different to the road surface un-
der the right wheels for a long period.
● when driving with snow chains.
Adjusting the tyre pressure settings (initialising the tyre pressure
monitoring system)
After any incident regarding the wheels of your vehicle, e.g. after modifying
the tyre pressure ⇒ page 255 or after changing or swapping wheels
⇒ page 255 you should - with the vehicle at a standstill and the engine run- ning - press ⇒ Fig. 190. The yellow warning lamp  will light up. Hold the
button down for 2 seconds until the warning lamp goes out and an acoustic
warning is given. You can now release the button.
If the wheels are subjected to extreme stress (e.g. heavy load), the tyre
pressure must be increased to the recommended value for the maximum
load (see the adhesive label on the inside of the fuel tank flap) and then
initialise the system. 

Tyre pressure warning lamp on
When you switch on the ignition, the tyre pressure warning lamp  will
light up for about 2 seconds. There is a fault in the system if the indicator
stays on permanently after switching on the ignition. The instrument panel
also display TMPS (Tyre Pressure Monitoring System). Please contact the
nearest specialised workshop as soon as possible.
The tyre pressure warning lamp  lights up if the tyre pressure on one or
more wheels is significantly lower than the tyre pressure setting which was
confirmed by the driver ⇒ 
.
WARNING
● If the tyre pressure warning lamp lights up  you must slow down
immediately and avoid any severe braking or steering manoeuvres. Stop
the vehicle as soon as possible and check the tyres and their pressure.
● The driver is responsible for maintaining correct tyre pressures.
Therefore, the tyre pressure must be regularly checked.
● Under certain conditions (e.g. driving at high speeds, on ice and snow
or on poor road surfaces) the tyre pressure warning lamp  may not light
up immediately or not at all.
● Please ask your Technical Service or specialised workshop whether
run-flat tyres can be used on your vehicle. Fitting this type of tyre in an
undue manner could lead to your driving licence being taken away from
you. Furthermore, it may led to damage to the vehicle or, under certain
circumstances, may cause accidents.
● If you change normal tyres for run-flat tyres or vice versa, the control
unit must be reprogrammed by the Technical Service or a specialised
workshop.
Note
If you did not press the button for the tyre pressure monitoring system to
confirm a new tyre pressure setting after making changes to the tyre pres-
sures or changing one or more wheels, the warning lamp  may light up
although the tyre pressures are correct. In this case, stop the vehicle as
soon as possible and, after examining the tyres, press the button for the
tyre pressure monitoring system. 

264If and when
Changing a wheel
Preparation work
What you must do before changing a wheel.
– If you have a flat tyre or puncture, park the vehicle as far away
from the flow of traffic as possible. Choose a location that is as
level as possible.
– All occupants should leave the vehicle. They should wait in a
safe place (e.g. behind the roadside crash barrier).
– Apply the handbrake firmly.
– Engage first gear .
– When towing a trailer: Unhitch the trailer from your vehicle.
– Take the tools and the spare wheel ⇒  page 261 out of the lug-
gage compartment.
WARNING
If you have a puncture in heavy traffic, switch on the hazard warning
lights and place the warning triangle in a visible location. This is for your
own safety and also warns other road users.
CAUTION
If you have to change the tyre on a gradient, block the wheel opposite the
wheel being changed by placing a stone or similar object under it to prevent
the vehicle from rolling away.
Note
Please observe legal requirements when doing so. 
Changing a wheel
Change the wheel as described below.
– Remove the wheel cover .
– Loosen the wheel bolts ⇒ page 265.
– Raise the vehicle with the jack ⇒ page 266.
– Take off the wheel with the flat tyre and then put on the spare
wheel ⇒ page 267.
– Lower the vehicle.
– Tighten the wheel bolts firmly in diagonal sequence with the
box spanner ⇒ page 265.
– Replace the cover. 
After changing a wheel
After changing the wheel, there are still tasks to complete. – Place the wheel with the defective tyre in the spare wheel well
and secure it.
– Put the tools and jack back in the luggage compartment. 

271
If and when
pressure is still lower than the specification the tyre is too badly
damaged and cannot be repaired using the tyre sealant.
Final check
– After about 10 minutes, stop to check the tyre pressure.
– If tyre pressure is less than 1.3 bar, the tyre is too badly dam-
aged. Do not drive on! You should obtain professional assis-
tance.
WARNING
● If you have a puncture in heavy traffic, switch on the hazard warning
lights and place the warning triangle in a visible location. This is for your
own safety and also warns other road users.
● Make sure your passengers wait in a safe place (for instance behind
the roadside crash barrier).
● Please observe the manufacturer's safety notes on the compressor
and the instructions supplied with the tyre sealant can.
● If it is not possible to build up a tyre pressure of 2.0 bar within 6 mi-
nutes this means that the tyre is too badly damaged. Do not drive on!
● Seek professional assistance if the repair of a tyre puncture is not
possible with the sealing product.
● If tyre pressure is less than 1.3 bar after driving about 10 minutes,
the tyre is too badly damaged. Do not drive on! Obtain technical assis-
tance.
CAUTION
Take special care if you have to repair a tyre on a slope.
Note
● Do not use the compressor for longer than 6 minutes. Otherwise, it
might overheat. When the compressor has cooled down, you can use it
again.
● If tyre sealant should leak out, leave it to dry and then pull it off like foil.
● After carrying out a tyre repair remember to buy a new tyre sealant can at
a specialised workshop. This will ensure that the Tyre Mobility System is op-
erative again.
● Please observe legal requirements when doing so. 

272If and when
Fuses
Introduction
Due to the constant update of vehicles, fuse assignments depending on
equipment and the use of the same fuse for various electrical components,
at the time of printing this manual it is not possible to provide an up-to-date
summary of the electrical components fuse positions. For detailed informa-
tion about the fuse positions, please consult a Technical Service.
In general, a fuse can be assigned to various electrical components. Like-
wise, an electrical component can be protected by several fuses.
Only replace fuses when the cause of the problem has been solved. If a
newly inserted fuse blows after a short time, you must have the electrical
system checked by a specialised workshop as soon as possible.
Additional information and warnings:
● Working in the engine compartment ⇒ page 235
WARNING
The high voltages in the electrical system can give serious electrical
shocks, causing burns and even death!
● Never touch the electrical wiring of the ignition system.
● Take care not to cause short circuits in the electrical system.
WARNING
Using unsuitable fuses, repairing fuses or bridging a current circuit with-
out fuses can cause a fire and serious injury.
● Never use a fuse with a higher value. Only replace fuses with a fuse of
the same amperage (same colour and markings) and size.
● Never repair a fuse.
● Never replace a fuse by a metal strip, staple or similar.
CAUTION
● To avoid damage to the vehicles electric system, before replacing a fuse
turn off the ignition, the lights and all electrical elements and remove the
keys from the ignition.
● If you replace a fuse with higher-rating fuse, you could cause damage to
another part of the electrical system.
● Protect the fuse boxes when open to avoid the entry of dust or humidity.
Dirt and humidity inside fuse boxes can cause damage to the electrical sys-
tem.
Note
● One single consumer could have more than one fuse.
● Several consumers could run over one single fuse. 

If and when
Changing bulbs. Halogen headlights Types of bulbs
You must only replace a bulb with a bulb of the same type. The name can be
found on the base of the bulb holder.
BulbTypeDipped beam headlights (halogen)12 V/55 W (H7 LL)Main beam headlights12 V/55 W (H1)Turn signal12 V/21 W (PY21W)Side lights12 V/5 W (W5W LL)
WARNING
● Take particular care when working on components in the engine com-
partment if the engine is warm. Risk of burns.
● Bulbs are highly sensitive to pressure. The glass can break when you
touch the bulb, causing injury.
● The high voltage element of gas discharge bulbs* (xenon light) must
be handled correctly. Otherwise, there is a risk of death.
● When changing bulbs, please take care not to injure yourself on sharp
parts in the headlight housing.
CAUTION
● Remove the ignition key before working on the electric system. Other-
wise, a short circuit could occur.
● Switch off the lights or parking lights before you change a bulb.
For the sake of the environment
Please ask your specialist retailer how to dispose of used bulbs in the prop-
er manner.
Note
● Depending on weather conditions (cold or wet), the front lights, the fog
lights, the tail lights and the turn signals may be temporarily misted. This
has no influence on the useful life of the lighting system. By switching on
the lights, the area through which the beam of light is projected will quickly
be demisted. However, the edges may continue to be misted.
● Please check at regular intervals that all lighting (especially the exterior
lighting) on your vehicle is functioning properly. This is not only in the inter-
est of your own safety, but also in that of all other road users.
● Before changing a bulb, make sure you have the correct new bulb.
● Do not touch the glass part of the bulb with your bare hands, use a cloth
or paper towel instead. Otherwise, the fingerprints left on the glass will va-
porise as a result of the heat generated by the bulb, they will be deposited
on the reflector and will impair its surface. 
