during this initial warm-up phase. It is therefore best to drive off immediately 
after starting the engine. Avoid running the engine at high speed.
Periodic maintenance
Periodic maintenance work guarantees 
that, before beginning a journey, you 
will not waste fuel. A well-serviced engine gives you the benefit of  improved 
fuel efficiency  as well as maximum reliability and an enhanced resale value.
A badly serviced engine can consume up to 10% more fuel than necessary.
Avoid short journeys
To reduce the consumption and emission of polluting gases, the engine and 
the exhaust filtration systems should reach the optimum  service tempera-
ture .
With the engine cold, fuel consumption is proportionally higher. The engine 
does not warm up and fuel consumption does not regularise until having 
driven some  four kilometres. This is the reason why we recommend avoiding 
short trips wherever possible.
Maintain the correct tyre pressures
Bear in mind that keeping  the tyres at an adequate pressure saves fuel. If the 
tyre pressures are just 1 bar too low, this can put the fuel consumption up by 
as much as 5%. Due to the greater roll ing resistance, under-inflation also 
increases  tyre wear and impairs handling.
The tyre pressures should always be checked when the tyres are  cold.
Do not use  winter tyres  all through the year: they will increase fuel consump-
tion by up to 10%.
Avoid unnecessary weight
Every kilo of  extra weight  will put up the fuel consumption, so it is worth 
checking the luggage compartment occasionally to make sure that no unnec-
essary loads are being transported.
A roof carrier is often left in place for the sake of convenience, even when it is 
no longer needed. At a speed of 100-120 km/h your car will use about 12%  more fuel as a result of the extra wind resistance caused by the roof carrier 
even when it is empty.
Save electrical energy
The engine activates the alternator, whic
h produces electricity. With the need 
for electricity, fuel consumption is also increased. Because of this, always 
turn off electrical equipme nt when you do not need them. Examples of equip-
ment that use a lot of electricity are: the fan at high speeds, the rear window 
heating or the seat heaters*.

Checking and refilling levels
228charge. 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 
engine, 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.
•
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 
reverse 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°
•
Ensure that the vent hose is always connected to the battery.
•
Never use a defective battery. This may be fatally explosive. Replace a 
damaged battery immediately.Caution
•
Never disconnect the  battery if the ignition is switched on or if the engine 
is running. This could damage the electrical system or electronic compo-
nents.
•
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 frost. If it “freezes” it will be damaged.
Checking the electrolyte level
The electrolyte level should be checked regularly in high-
mileage vehicles, in hot countries and in older batteries.– Open the bonnet and open the battery cover at the front  ⇒ in 
“Safety instructions on working in the engine compartment” on 
page 213  ⇒ in “Warnings on handling the battery” on 
page 227.
– Check the colour display in the "magic eye" on the top of the  battery.
– If there are air bubbles in the window, tap the window gently until  they disperse.The position of the battery is show n in the corresponding engine compart-
ment diagram  ⇒page 273.
The round window (“magic eye”) on the top of the battery changes colour, 
depending on the charge level and electrolyte level of the battery.
If the colour in the window is  colourless or bright yellow, the electrolyte level 
of the battery is too low. Have the battery checked by a qualified workshop.
The colours green and black are used by the workshops for diagnostic 
purposes.

Wheels and tyres
230Wheels and tyresWheelsGeneral notesAvoiding damage
– If you have to drive over a kerb or similar obstacle, drive very 
slowly and as near as possible at a right angle to the kerb.
– 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
– Mark tyres when you remove them  to indicate the direction of 
rotation. This ensures you will be able to install them correctly 
when you replace them.
– 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  ⇒page 190.
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 re
adily visible. If you notice unusual 
vibrations or the car pulling to one side, this may indicate that one of the tyres 
is damaged. The tyres should be checked immediately by an Authorised 
Service Centre.
Tyres with directional tread pattern
An arrow on the tyre sidewall indicates  the direction of rotation on tyres with 
directional tread. Always observe the di rection 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 in the first 500 km. Drive particu-
larly carefully to avoid risk of accident.
•
Never drive with damaged tyres. This may cause an accident.
•
If you notice unusual vibration or if the vehicle pulls to one side when 
driving, stop the vehicle immediately and check the tyres for damage.
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 inflatio n 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.

Practical tips
Te c h n i c a l  D a t a
Wear indicators
The original tyres on your vehicle have 1.6 mm high “tread wear indicators” 
⇒
page 232, fig. 168 , running across the tread. Depending on the make, 
there will be six to eight 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 indica-
tors). Worn tyres must be replaced. Different figures may apply in export 
countries  ⇒.
Tyre pressure
Incorrect tyre pressure causes premature wear and could cause tyre blow-out. 
For this reason, the tyre pressure should be checked at least once per month 
⇒ page 230.
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 advisable 
to change them around as shown  ⇒page 232, fig. 169 . All the tyres will then 
last for about the same time.
Wheel balance
The wheels on new vehicles are balanced. However, various factors encoun-
tered in normal driving can cause them to become unbalanced, which results 
in steering vibration.
Unbalanced wheels should be rebalanced, as they otherwise cause excessive 
wear on steering, suspension and tyres. A wheel must also be rebalanced 
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 align-
ment checked by an Authorised Service Centre.
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 is worn down to 
the tread wear indicators. 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 an Authorised Service Centre.
•
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.Anti-puncture tyres

How to jump start: description⇒fig. 199    shows the flat battery and   the charged battery.
Jump lead terminal connections
– Switch off the ignition on both vehicles  ⇒.
1.  Connect one end of the red jump lead to the positive  ⇒fig. 199 
 terminal of the vehicle with the flat battery  ⇒.
2.  Connect the other end of the red jump lead to the positive  terminal   in the vehicle providing assistance.
3.  Connect one end of the black jump lead to the negative terminal   on the battery of the vehicle providing assistance. 4.  Connect the other end of the black jump lead   to a solid metal 
component which is bolted on to the engine block, or onto the 
engine block itself of the vehicle with the flat battery. Do not 
connect it to a point near the battery  ⇒.
5.  Position the leads in such a way that they cannot come into  contact with any moving parts in the engine compartment.
Starting
6.  Start the engine of the vehicle  with the boosting battery and let 
it run at idling speed.
7.  Start the engine of the car with the flat battery and wait one or  two minutes until the engine is “running”.
Removing the jump leads
8.  Before you remove the jump leads, switch off the headlights (if  they are switched on).
9.  Turn on the heater blower and rear window heater in the vehicle  with the flat battery. This helps minimise voltage peaks which are 
generated when the leads are disconnected.
10. When the engine is running, disconnect the leads in reverse  order to the details given above.
Connect the battery clamps so they ha ve good metal-to-metal contact with 
the battery terminals.
If the engine fails to start, switch off the starter after about 10 seconds and 
try again after about half a minute.
