For the sake of the environment
Never warm up the engine when the vehicle is standing. Drive off right
away. Through this the engine reaches its operating temperature more
rapidly and the pollutant emissions are lower.
Petrol engines
These engines are fitted with a starter system which selects the correct
fuel/air mixture for every external air temperature.
•Do not operate accelerator before and when starting engine.
•Interrupt the attempt at starting after 10 seconds if the engine does not
start right awayand wait for about 30 seconds before repeating the
attempt.
•It is possible that the fuse on the electrical fuel pump is defect if the
engine still does not start. Check the fuse and replace it if necessary
⇒ page 260.
•If the engine does not start, contact the nearest specialist garage to
obtain professional assistance.
It may be necessary, if the engine is very hot, to slightly depress the
accelerator after the engine has started.
Diesel engines
Glow plug system
Diesel engines are equipped with a glow plug system, the preglow period
being controlled automatically in line with the coolant temperature and
outside temperature. The preglow indicator light
comes on after the ignition has been
switched on.
You should not switch on any major electrical components during
the heating period otherwise the vehicle battery will be drained
unnecessarily.
•You should start the engine immediately after the glow plug warning
light has gone out.
•The glow plug warning light will come on for about one second if the
engine is at a normal operating temperature or if the outside temperature
is above +5°C. This means that you can start the engine right away.
•Interrupt the attempt at starting after 10 seconds if the engine does not
start right awayand wait for about 30 seconds before repeating the
attempt.
•It is possible that the fuse on the diesel preglow system is defect if the
engine still does not start. Check the fuse and replace it if necessary
⇒ page 260.
•If the engine does not start, contact the nearest specialist garage to
obtain professional assistance.
Starting the engine after fuel tank has run dry
It may take longer than normal to start the engine after refuelling if the fuel
tank has run completely dry - up to one minute. This is because the fuel
system must first of all be filled while the attempting to start the engine.
Switching the engine off
– Turn the ignition key into position ⇒page 121, fig. 115 .A1

Fuel217
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
– Press the fuel tank flap closed.
The correct grade of fuel for your vehicle as well as the tyre size and infla-
tion pressures are stated on a sticker affixed to the inside of the fuel filler
flap. Further information on fuel ⇒page 214, “Fuel”.
The fuel tank has a capacity of about 62 litres.
WARNING
Pay attention to any legal requirements if you do carry a spare
canister in the vehicle. We do not recommend carrying any fuel
canisters in your vehicle for safety reasons. The canister can be
damaged in the event of an accident and fuel may leak out.
Caution
•Remove any fuel which has spilled onto the paintwork of your vehicle
immediately. This particularly applies to biodiesel - risk of paint damage!
•Vehicles fitted with catalytic converter should never be allowed to let
the fuel tank to run completely empty. An irregular supply of fuel to the
engine can result in misfiring and unburnt fuel may get into the exhaust
system, which may result in overheating and damage to the catalytic
converter.
For the sake of the environment
The fuel tank is full just as soon as the pump nozzle switches off for the
first time, provided the nozzle has been operated properly. You should not
continue refuelling - otherwise the expansion chamber in the fuel tank will
also be filled with fuel. Fuel might flow out of the tank when it heats up.
Emergency release of fuel filler flap
If the electric lock is faulty, you can also unlock the fuel filler flap
manually.
– Open the boot lid/luggage compartment door.
– Unscrew the clip attaching the right-hand side trim panel and
pull the trim panel off the body.
– Pull on the loop in direction of arrow in order to unlock the fuel filler flap ⇒fig. 171 .
WARNING
When unlocking the fuel filler flap manually, pay attention to sharp
edges of the body - risk of injury!

Breakdown assistance259
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
For technical reasons it is not possible to tow-start a car fitted with an
automatic gearbox
.
WARNING
There is high risk of having an accident when tow-starting a
vehicle, when for example the towed vehicle runs into the towing
vehicle.
Caution
Vehicles which are fitted with a catalytic converter should not be tow-
started over a distance of more than 50 metres. Unburnt fuel may get into
the catalytic converter and damage it.
Towing in a vehicle fitted with a manual gearbox
Please refer to the notes ⇒page 257.
The car can be towed in with a tow bar or a tow rope or with the front or
rear wheels raised. The maximum towing speed is 50 km/h.
Towing of a vehicle with an automatic gearbox
Please refer to the notes ⇒page 257.
The car can be towed in with a tow bar or a tow rope. Refer at the same
time to the following guidelines:
•Move selector lever into N .
•The maximum towing speed is 50 km/h.
•The maximum permissible towing distance is 50 km. The gear oil
pump does not operate when the engine is not running and the gear would
not be adequately lubricated at higher speeds and over longer towing
distance.
Caution
If the vehicle is towed in by a recovery vehicle, it should only be towed in
with the front wheels raised. If the vehicle is raised at rear, the automatic
gearbox is damaged!
Note
The vehicle must be transported on a special vehicle or trailer if it is not
possible to tow in the vehicle in the way described or if the towing distance
is greater than 50 km.

Fuses and light bulbs
262
The power windows and the power seats are protected by automatic
circuit breakers which switch on again automatically after a few seconds
after the overload has been eliminated - e.g. frozen windows.
Bulbs
Changing bulbs
The relevant lamp must always be switched off before a light bulb is
replaced.
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,
serviette or something similar.
Defect light bulbs should only be replaced with light bulbs of the same
type. The designation is located on the light socket or the glass bulb.
Changing certain bulbs is not something which you can do yourself, but
requires to be done by a specialist. Other parts of the vehicle must be
