EPC fault light
(petrol engine)
The
(Electronic Power Control) warning light comes on for a few seconds when
the ignition is switched on.
There is a fault in the engine control system if the warning light
does not go out
or comes on or flashes while driving. The engine management system selects an
emergency programme which enables you to drive to the nearest specialist garage
by adopting a gentle style of driving.
The following text will be displayed in the information display*:
ENGINE FAULT WORKSHOP!
Glow plug system
(diesel engine)
The warning light
lights up for a cold engine when switching on the ignition
(pre-heat position) 2 ⇒page 100. Start the engine after the indicator light goes out.
The glow plug indicator light will come on for about 1 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.
There is a fault in the glow plug system if the warning light
does not come on or
lights up continuously, contact a specialist garage as soon as possible to obtain
assistance.
There is a system fault in the engine control system if the warning light
has
started to flash while driving. The engine management system selects an emer-
gency programme which enables you to drive to the nearest specialist garage by
adopting a gentle style of driving.
The following text will be displayed in the information display*:
ENGINE FAULT WORKSHOP!
Turn signal system for vehicles towing a trailer*
Only if a trailer is attached to the vehicle, the indicator light
flashes together with
the turn signals.The indicator light
does not flash if a turn signal light on the trailer or on the
vehicle is not operating.
Coolant temperature/coolant level
After the ignition is switched on the warning light lights up blue until the engine
reaches operating temperature
1). Avoid running at high engine speeds, at full
throttle and at severe engine loads. The blue warning light goes out once the oper-
ating temperature has been reached .
The coolant temperature is too high or the coolant level too low if the warning light
lights up red or flashes red while driving.
3 peeps sound as an additional warning signal.
In this case stop and switch the engine off and check the coolant level; top up the
coolant as necessary ⇒page 190, “Replenishing the coolant”.
Do not continue your journey if for some reason it is not possible under the
conditions prevailing to top up with coolant. Keep the engine switched off and
obtain professional assistance from a specialist garage, otherwise it could lead to
severe engine damage.
If the coolant is within the specified range, the increased temperature may be
caused by an operating problem at the coolant fan. Check the fuse for the coolant
fan, replace it if necessary ⇒page 221, “Fuse assignment at the battery (automatic
gearbox)”.
Do not continue driving if the warning light does not go off although the fluid is at
the correct level and also the fuse of the fan is in proper order. Contact a specialist
garage to obtain assistance.
Please also refer to the additional instructions ⇒page 189, “Cooling system”.

Technical Data
Shifting up gears
– One-touch forward of the selector lever (in the Tiptronic position)
⇒page 110, fig. 131 .
Shifting down gears
– One-touch back of the selector lever (in the Tiptronic position) .It is possible to switch over to manual both when the car is stationary and also when
driving.
When you accelerate, the gearbox shifts up automatically in gears 1, 2, 3, 4 and 5
into the next higher gear just before the maximum permissible engine speed is
reached.
If you select a lower gear, the automatic gearbox does not shift down until there is
no risk of the engine overrevving.
If you operate the kickdown function, the gearbox shifts into a lower gear in line
with the vehicle speed and engine speed.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.
It is possible to continue to move the selector lever into all the positions. In the
positions D and S the gearbox remains engaged in the 3rd gear. It is also possible to
continue to engage reverse gear in the position R.
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.
Tow-starting and towing vehicle Tow-starting a vehicle
It is not possible to tow-start or push-start vehicles fitted with automatic gearbox.
you can use jump-start cables connected to the battery of another vehicle for
starting your car if the vehicle battery is flat ⇒page 211.
Towing a vehicle
Please pay attention to the following information if it comes necessary to tow-in
your car ⇒page 213.

Technical Data
•
the structure of the tyre is damaged,
•
the vehicle is loaded to one side or with a load on the roof,
•
the wheels of an axle are loaded heavily (e.g. when towing a trailer or when
driving uphill or downhill),
•
the vehicle is operated in unfavourable winter conditions or on an unfirm
ground,
•
Snow chains or emergency wheel* are mounted,
•
the driver has a sporty style of driving (with sharp acceleration and high speed
when cornering).
Basic setting of tyre inflation pressure-control system
After changing the tyre inflation pressures or after changing one or several wheels,
a basic setting of the system must be carried out as follows.
•
Inflate all tyres to the specified inflation pressure ⇒page 198.
•
Switch on the ignition.
•
Press button
⇒page 160, fig. 172 for more than 2 seconds. While
pressing the button, the warning light
lights up. At the same time the basic
values are stored, which is confirmed with an acoustic sound and then the warning
light
goes out.
•
If the warning light
does not go out after the basic setting, there is a fault in
the system. Have the vehicle inspected by your nearest specialist garage.
Function description
After the basic setting of the system the “adaptation” of the tyre inflation pressures
and then the tyre pressure control in the individual tyres are performed.
Warning light
lights up
If the tyre inflation pressure of at least one wheel is insufficiently inflated in compar-
ison to the stored basic value, the warning light
⇒ lights up. Inflate all tyres
to the specified inflation pressure ⇒page 198, “Tyre life” and then perform a basic
setting of the system.
Warning light
flashes
If the warning light flashes, there is a system fault. Have the vehicle inspected by
your nearest specialist garage.
WARNING
•
When the warning light
lights up, immediately reduce the speed and
avoid sudden steering and brake manoeuvres. Please stop the vehicle
without delay at the nearest possible stop and inspect the tyres and their
inflation pressures.
•
The driver is responsible for the correct tyre inflation pressures. For this
reason, the tyre inflation pressures must be checked regularly.
•
Under certain circumstances (e.g. sporty style of driving, wintry or
unpaved roads) the warning light
can be delayed or does not light up at
all.
•
The tyre inflation pressure-control system does not take away the
responsability from the driver for the correct tyre inflation pressure.Note
The tyre inflation pressure-control system:•
does not replace the regular tyre inflation pressure control, because the system
cannot detect an even pressure loss;
•
cannot warn in case of very rapid tyre inflation pressure loss, e.g. in case of
sudden tyre damage. In this case carefully bring the vehicle to a standstill without
sudden steering movements and without sharp braking.
