Starting-off and Driving
112
Starting the engine
General
You can only start the engine only using an original ignition key.
•Place the gearshift lever into neutral (or place the selector lever to the position
P or N in the case of an automatic gearbox) and put on the handbrake firmly before
starting the engine.
•The clutch pedal should be fully depressed when starting the engine which
means that the starter only has to crank the engine.
•Let go of the key as soon as the engine starts otherwise there may be damage
to the starter.
The engine running noises ma y louder at first be louder for a short time after
starting the cold engine until oil pressure can be built up in the hydraulic valve
clearance compensation. This is quite no rmal and is not an operating problem.
If the engine does not start ...
You can use the battery of anothe r vehicle as a jump-start aid ⇒page 236.
It is only possible to tow-start vehicles fitted with a manual gearbox. The tow-
starting distance must not be more than 50 metres.
WARNING
•Never run the engine in non ventilat ed or enclosed areas. The exhaust
gases of the engine contain besides the odorless and colourless carbon
monoxide a poisonous gas - hazard! Carbon monoxide can cause uncon-
sciousness and death.
•Never leave your vehicle unattended with the engine running.
Caution
•The starter may only be operated (ignition key position ), if the engine is not
running. If the starter is immediately operated after switching off the engine, the
starter or the engine can be damaged.
•Avoid high engine revolutions, full throttle and high engine loads as long as the
engine has not yet reached its normal oper ating temperature - risk of damaging the
engine!
•Vehicles which are fitted with an exhaust gas catalytic conver ter should not be
tow-started over a distance of more than 50 metres.
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 befo re 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 241.
•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 temper-
ature.
The preglow indicator light
comes on after the igniti on has been switched on.

Starting-off and Driving113
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
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 th e 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 241.
•Contact the nearest specialist garage to obtain professional assistance.
Starting the engine after the 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 off the engine
– The engine can be switched off by turning the ignition key from posi- tion into ⇒page 111, fig. 121 .
WARNING
•Never switch off the engine before the vehicle is stationary - risk of acci-
dent!
•The brake booster only operates when the engine is running. Greater
physical effort for braking is required when engine is switched off. Because
if you do not stop as normal, this can cause an accident and severe injuries.
Caution
you should not switch the engine off right away at the end of your journey after the
engine has been operated for a lengthy peri od at high loads but should be allowed
it to run at idling speed for about 2 minutes. This prevents any accumulation of heat
when the engine is switched off.
Note
•The radiator fan may continue running fo r a further 10 minutes or so after the
engine and the ignition have been switched off. The coolant fan may, however, also
switch on again after some time if the coolant temperature rises because of an
accumulation of heat in the engine or if the engine is warm and the engine
compartment is additionally heated by strong sunlight.
•This is why particular care is required when carrying out any work in the engine
compartment ⇒page 209, “Working in the engine compartment”.
Shifting (manual gearbox)
Shift into reverse only when the car is stationary. Depress the clutch pedal and hold
it fully depressed. Wait a moment before engaging reverse gear in order to avoid
any shift noises.
The reversing lights will come on once re verse gear is engaged, provided the igni-
tion is on.

•If you are stopping at a hill (downhill section), never try to hold the car
stationary with the gear engaged by me ans of the “accelerator”, this means
by letting the clutch slip. This can lead to overheating of the clutch. If there is
a risk of overheating of the clutch due to overload, the clutch is opened auto-
matically and the vehicle rolls backward - risk of accident!
•If you must stop at a slope, depress and hold the brake pedal, so that you
can prevent the vehicle from rolling back.
Caution
•The double clutch on the automatic gear box DSG is equipped with an overload
protection. If you make use of the uphill func tion on a vehicle which is stationary or
driving slowly uphill, it will result in an increase of thermal stress of the clutches.
•An overheating of the clutches can be de tected by the flashing of the selector
level indicator and the “jerk” of the clut ches, finally the clutches are opened. The
power transmission from the engine to the front wheels is interrupted and as a
result of this the vehicle can no longer be driven. If the clutch opens automatically,
depress the brake pedal, wait a few se conds and only then continue driving.
Selector lever positions
The current selector lever position is indicated in the information display of the
instrument cluster ⇒fig. 133 .

Emergency programme
An emergency programme exists in the event of a fault in the system.
The gearbox operates in a corresponding emergency programme if there are func-
tional faults in the gearbox electronics. This is indicated by all of the segments in the
display lighting up or going out.
A functional fault can ha ve the following effect:
•The gearbox only shifts into certain gears.
•The reverse gear R cannot be used.
•The manual shift programme (Tiptronic) is switched off in the emergency mode.
If the gearbox has switched over to emergency mode, drive to the nearest
specialist garage in order to have the fault rectified.

Airbag system161
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
•When disposing of vehicle or parts of the airbag system, it is important
to comply with the national legal requirements.
When are the airbags deployed?
The airbag system is designed in such a way that the driver and front passenger
airbag are deployed in the event of a frontal collision of major severity.
In the case of a violent side crash , the front side airbag* on the side of the car at
which the collision occurs, is deployed toge ther with the rear side airbag and the
head airbag*.
In certain accident situations, the front airbags as well as the side and head airbag
may be deployed together.
The airbags are not deployed in the case of minor frontal and side collisions, in the
case of rear-end collisi ons and vehicle rollover.
Deployment factors
It is not possible to state globally which deployment conditions apply to the airbag
system in every situation as the circumstances which exist in the case of accidents
vary greatly. An important role in this case , for example, is played by factors such as
the type of object (hard, soft) against whic h the vehicle impacts or the type of object
against which the vehicle impa cts, the angle of impact, the relative vehicle speed
during the accident etc.
A decisive factor for the deployment of the airbags is the deceleration which occurs
during a collision. The control unit analyses the nature of the collision and activates
the relevant restraint system. If the vehi cle deceleration which occurs and is meas-
ured during the collision remains below the prescribed reference values specified
in the control unit, the airbags are not deployed although the vehicle may well
suffer severe damage to the bodywork as a consequence of the accident.
The airbags are not deployed if:
•ignition off,
•a minor frontal collision,
•a minor side collision,
•a rear-end collision,
•rollover of the vehicle
Note
•a grey white, non harmful gas is released when airbag is inflated. This is perfectly
normal and is not an indication of a fire in the vehicle.
•the dash panel must be replaced afte r the front passenger airbag has been
deployed.
•in the event of an accident in which the airbags are deployed:
− the interior lighting comes on (if the swit ch for the interior light is in the door
contact position),
− the hazard warning light is switched on,
− all the doors are unlocked,
− the battery in the luggage compartment* is switched off;
− the fuel supply to the engine is interrupted.
