Checking and refilling levels
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 very corrosive and caustic. 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 electrical system,
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 also freeze at temperatures close to 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 ⇒ 
in Important safety warnings for han-
dling a vehicle battery on page 247 and ⇒ . 
Safety FirstOperating InstructionsPractical TipsTechnical Specifications

248Checking and refilling levels
–Switch off the ignition and all electrical equipment.
– Only if fast-charging: both battery cables must be disconnected
(first the negative cable, then the positive cable).
– Connect the charger cables to the battery terminals, noting the
colour code (red = positive; black or brown = negative).
– Now connect the battery charger to the power socket and switch
on.
– After charging the battery: switch off the battery charger and
disconnect the power point cable.
– Finally disconnect the charger cables from the battery.
– If necessary, reconnect both battery cables to the battery (first
the positive cable, then the negative cable).
When charging with a low current (for instance with a small battery charger)
the battery does not normally have to be disconnected. However, both bat-
tery cables must be disconnected before fast-charging the battery with a
high current. However, always follow the instructions given by the manufac-
turer of the battery charger.
The fast-charging procedure for a battery is dangerous ⇒ 
in Important
safety warnings for handling a vehicle battery on page 247, as it requires a
special charger and the corresponding level of knowledge. We therefore rec-
ommend that this work should only be performed by a specialised work-
shop.
A flat battery can freeze at temperatures of around 0°C. The battery must be
defrosted before charging ⇒ 
. It is advisable to replace the battery if it has
frozen, because the ice can crack the battery casing and allow the battery
acid to escape.
The battery caps should not be opened while the battery is being charged.
WARNING
Never charge a frozen battery. Failure to comply could result in an explo-
sion.

General notes
Avoiding damage
– If you have to drive over a kerb or similar obstacle, drive very
slowly and at a right angle.
– Keep grease, oil and fuel off the tyres.
– Inspect the tyres regularly for damage (cuts, cracks or blisters,
etc.). Remove any foreign objects embedded in the treads.
Storing tyres
– When you remove the tyres, mark them in order to maintain the
same direction of rotation when they are installed again.
– When removed, the wheels and/or tyres should be stored in a
cool, dry and preferably dark location.
– Store tyres in a vertical position if they are not fitted on wheel
rims.
New tyres
New tyres have to be run in.
The tread depth of new tyres may vary, according to the type and make of
tyre and the tread pattern. Concealed damage
Damage to tyres and rims is often not readily visible. If you notice unusual
vibrations or the vehicle pulling to one side, this may indicate that one of
the tyres is damaged. The tyres should be checked immediately by a Techni-
cal Service.
Tyres with directional tread pattern
An arrow on the tyre sidewall indicates the direction of rotation on tyres with
directional tread. Always observe the direction of rotation indicated when
fitting the wheel. This guarantees optimum grip and helps to avoid aqua-
planing, excessive noise and wear.
WARNING
● New tyres do not have maximum grip during the first 500 km. Drive
particularly carefully to avoid possible accidents.
● Never drive with damaged tyres. This may cause an accident.
● If you notice unusual vibrations or if the vehicle pulls to one side
when driving, stop the vehicle immediately and check the tyres for dam-
age.

Checking tyre pressure
The correct tyre pressure can be seen on the sticker on the
inside of the tank flap.
1. Read the required tyre inflation pressure from the sticker. The values refer to Summer tyres. For Winter tyres, you must add
0.2 bar to the values given on the sticker. 
Safety FirstOperating InstructionsPractical TipsTechnical Specifications

250Wheels and tyres
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
tank flap. The tyre pressure values given are for cold tyres. Do not reduce
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. 

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 engine 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. 189 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 253 or after changing or swapping wheels
⇒ page 253 you should - with the vehicle at a standstill and the engine run- ning - press ⇒ Fig. 189. 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. 

Wheels and tyres
Tyre service life
The service life of tyres is dependent on tyre pressure, driv-
ing style and fitting.
Fig. 190 Tyre tread wear
indicators
Fig. 191 Diagram for
changing wheels Wear indicators
The original tyres on your vehicle have 1.6 mm high “tread wear indicators”
⇒ Fig. 190, running across the tread. Depending on the make, there will be
6 to 8 of them evenly spaced around the tyre. Markings on the tyre sidewall
(for instance the letters “TWI” or other symbols) indicate the positions of
the tread wear indicators. The minimum tread depth required by law is
1.6 mm (measured in the tread grooves next to the tread wear indicators).
Worn tyres must be replaced. Different figures may apply in export countries
⇒ 
.
Tyre pressure
Under-inflation or over-inflation will reduce the life of the tyres considerably
and also impair the vehicle's handling. The inflation pressures are listed on
a sticker on the inside of the fuel tank flap.
Correct inflation pressures are very important, especially at high speeds.
The pressure should therefore be checked at least once a month and before
starting any long journey.
Tyre pressure monitoring (RKA+)*
Monitoring of the tyre pressures is based on the tyre pressures you have
stored. The tyre pressure monitoring system cannot function as intended if
you store tyre pressure settings for a normal load, but then drive with the
vehicle fully laden. The tyre pressure must be adapted to the actual load
and stored accordingly in the tyre pressure monitoring system ⇒ page 251.
Driving style
Fast cornering, heavy acceleration and hard braking all increase tyre wear.
Changing wheels around
If the front tyres are worn considerably more than the rear ones it is advisa-
ble to change them around as shown ⇒ Fig. 191. All the tyres will then last
for about the same time. 
Safety FirstOperating InstructionsPractical TipsTechnical Specifications

254Wheels and tyres
Wheel balance
The wheels on new vehicles are balanced. However, various factors encoun-
tered in normal driving can cause them to become unbalanced, which re-
sults in steering vibration.
Unbalanced wheels should be rebalanced, as they otherwise cause exces-
sive wear on steering, suspension and tyres. A wheel must also be reba-
lanced when a new tyre is fitted.
Incorrect wheel alignment
Incorrect wheel alignment causes excessive tyre wear, impairing the safety
of the vehicle. If tyres show excessive wear, you should have the wheel
alignment checked by a Technical Service.
WARNING
There is a serious danger of accidents if a tyre bursts during driving!
● The tyres must be replaced at the latest when the tread wear indica-
tors are worn ⇒ page 253. Failure to do so could result in an accident.
Worn tyres do not grip well at high speeds on wet roads. There is also a
greater risk of aquaplaning.
● At continuously high speeds, a tyre with insufficient pressure flexes
more. This causes it to overheat. This can cause tread separation and tyre
blow-out. Risk of accident. Always observe the recommended tyre pres-
sures.
● If tyres show excessive wear, you should have the running gear
checked by a Technical Service.
● Keep chemicals such as oil, fuel and brake fluid away from tyres.
● Damaged wheels and tyres must be replaced immediately!
For the sake of the environment
Under-inflated tyres will increase fuel consumption. Run-flat tyres*
Run-flat tyres allow you to continue driving even with a
punctured tyre, in the majority of cases.
In vehicles that are factory-fitted with run-flat tyres 1)
the loss of tyre
pressure is indicated on the instrument panel.
Driving with run-flat tyres (emergency running)
– Leave the ESC/ASR on (Electronic Stability Control), or switch it
on ⇒  page 71.
– Continue driving carefully and slowly (80 km/h maximum).
– Avoid sudden manoeuvres and sharp turns.
– Avoid driving over obstacles (for example kerbs) or potholes.
– Pay attention if the ESC/ASR activates often, if smoke comes
from the tyres or there is a smell of rubber, if the vehicle vi-
brates or there are clattering noises. If any of these occur, stop
the vehicle.
The run-flat tyres have a tag on the side of the tyre, with the description:
“DSST”, “Eufonia”, “RFT”, “ROF”, “RSC”, “SSR” or “ZP”.
The sides of this type of tyre are reinforced. When the tyres lose air they are
supported on the sides (emergency driving).
The loss of pressure in the tyre is shown on the instrument panel. You can
then drive a maximum of 80 km and if the circumstances are favourable (for
example, low load), even more. 
