Instruments and warning lights
303 peeps sound as an additional warning signal. Do not continue your journey
if for some reason it is
not possible under the condi-
tions prevailing to top up with oil.
Keep the engine switched off
and obtain profes-
sional assistance from a specialist garage, otherwise it could lead to severe engine damage. Do not drive any further
if the warning light flashes even if the oil is at the correct
level. Do not run the engine
not at idling speed either. Contact the nearest specialist
garage to obtain professional assistance. The following text will be displayed in the information display*:
Oil Pressure: Engine off! Owner's manual!
The warning light
lights up yellow* (oil quantity too low)
If the warning light lights up yellow, the quantity of oil in the engine is probably too low. Check as soon as possible the oil level or top up
page 167 with engine oil.
A peep sounds as an additional warning signal.The following text will be displayed in the information display*:
Check oil level!
The warning light will go out if the bonnet is le
ft open for more than 30 seconds. If no
engine oil has been replenished, the warning light will come on again after driving about 100 km. The warning light
flashes yellow* (engine oil level sensor faulty)
A fault on the engine oil level sensor is indicated additionally by an audible signal and the warning light coming on several times after the ignition has been switched on. In this case have the engine inspected without delay by a specialist garage.The following text will be displayed in the information display*:
Oil sensor. Workshop!
WARNING
If you must stop for technical reasons, then park the vehicle at a safe
distance from the traffic and switch off the engine and switch on the hazard warning light system
page 51.
The red oil pressure light
is not an oil level indicator! One should there-
fore check the oil level at regular interval
s, preferably after every refueling stop.
Pay attention to the following instructions
page 166, “Working in the
engine compartment” before checking
the coolant fluid level and opening the
bonnet.Open door
The warning light
comes on if one or several doors are opened or if the boot lid is
opened. If one of the doors opens whil
e driving, the warning light lights
up and an
audible signal sounds. The warning light comes on even when the ignition is switched off. The warning light lights up for a maximum of 5 minutes. On vehicles with information display* this wa
rning light is replaced by a vehicle symbol
page 23.Windshield washer fluid level*
The warning light
comes on when the ignition is swit
ched on if there is insufficient
fluid in the windshield washer system. Top up with liquid
page 176.
The following text will be displayed in the information display*:

Control system for exhaust
The warning light
comes on after the ignition has been switched on.
If the warning light does not go out after starti
ng the engine or it li
ghts up when driving,
a fault exists in an exhaust relevant co
mponent. The engine management system
selects an emergency programme which enables you to drive to the nearest specialist garage by adopting a ge
ntle style of driving.

Engine oilCheck engine oil level The dipstick indicates the le
vel of oil in the engine.
Checking the oil level– Ensure that the vehicle is po
sitioned on a level surface.
– Switch the engine off.– Open the bonnet
in “Working in the engine compartment” on page 166.
– Wait a few minutes and pull out the oil dipstick
.
– Wipe off the dipstick with a clea
n cloth and insert it again fully.
– Then withdraw the dipstick again and read off the oil level.Oil level within range –You must
not
top up the oil.
Oil level within range –You
may
top up the oil. It is possible that the oil level may then be within range
after doing this.
Oil level within range –You
must
top up the oil. It is ideal, once this
is done, to keep the oil level within
range .

Wheels and TyresWheelsGeneral information
New tyres do not offer optimal grip at first and should therefore be run in for about
500 km at a moderate speed and an appropri
ately cautious style of driving. You will
also profit from longer tyre life.
The tread depth of new tyres may differ be
cause of design features and the config-
uration of the tread (depending on the type of tyre and the manufacturer).
Drive over curbs on the side of the road
and other such obstacles slowly and,
where possible, at a right angle in order
to avoid damage to tyres and wheel trims.
Inspect your tyres from time to time
for damage (punctures, cuts, splits and
bulges). Remove foreign bodies from the tyre profile.
Damage to tyres and wheels is frequently
not visible. Unusual vi
brations or pulling
of the vehicle to one side coul
d be a sign of tyre damage.
Please reduce your speed
immediately and stop if you su
spect that a wheel is damaged.
Inspect the tyres for
signs of damage (bulges, splits, etc.). If no
visible damage is present, please drive at an
appropriately slow speed and carefully to the nearest specialist garage in order to have your vehicle inspected.
Also protect your tyres from contact with oil, grease and fuel.
Immediately replace any dust caps of
the valves which have got lost.
Mark wheels before removing them so that
their previous dire
ction of running can
be maintained when mounted them again.
Always store wheels or tyres which been removed in a cool, dry and, where
possible, dark place. Tyres which are not fixed to a wheel trim should be stored upright. Unidirectional tyres* The direction of rotation of the tyres is mark
ed by arrows on the
wall of the tyre. This
indicates the direction of rotation of the tyre, and it is essential that the tyres are fitted on to run in this direction. Only then are
the tyres able to provide the optimal proper-
ties in terms of grip, low nois
e, wear-and-tear and aquaplaning.
Further information concerning th
e use of unidirectional tyres
page 182.
WARNING
New tyres during the first 500 km do not offer optimal grip and should
therefore be run appropriately - risk of accident!
Never drive with damaged tyres - risk of accident!Note
Please observe the various differing legal requirements regarding tyres.Ty re l i feThe life of your tyres very much depends on the following points: Tyre pressure The working life of tyres will be shortened considerably if the tyres are insufficiently or over-inflated and this will have an adverse
effect on the handli
ng of your vehicle.
Correctly inflated tyres are of particular importance when travelling at
high speeds
. It
is therefore good to check the pressure at
least once a month and also before setting
off on a long trip. Please do not forget the spare wheel* when checking the tyres. The tyre inflation pressures for
summer tyres
are indicated on the inside of the fuel
filler flap
fig. 147
. The inflation pressures for
winter tyres
are 20 kPa (0.2 bar) higher
than those for summer tyres
