2008 AUDI A5 COUPE oil temperature

Instruments and warning/indicator lamps
12Warning symbol in instrument cluster

If the symbol
 lights up in the display, this means that either the
coolant temperature is too high or the coolant level is too low
⇒ page 32 .
If the needle is at the top end of the dial, this means the coolant
temperature is too high. Stop the vehicle, switch off the engine and
wait for it to cool down. If the warning lamp starts flashing again
after just a short distance, contact a qualified workshop.
WARNING
•
Before opening the bonnet and checking the coolant level,
please observe the warning information on ⇒page 231, “Working
on components in the engine compartment”.
•
Never open the bonnet if you can see or hear steam or coolant
escaping from the engine compar tment; there is a risk of being
scalded. Wait until you can no lo nger see or hear escaping steam
or coolant.Caution
•
Additional lights and other accesso ries in front of the air inlet
reduce the cooling effect of the radiator. At high outside tempera-
tures and high engine loads, there is a risk of the engine over-
heating.
•
The front spoiler also ensures proper distribution of the cooling
air when the vehicle is moving. If the spoiler is damaged this can
reduce the cooling effect, which could cause the engine to overheat.
You should obtain professional assistance.
Rev counter
The rev counter indicates the number of engine revolu-
tions per minute.You should select a lower gear if the engine speed drops below
1500 rpm. The start of the red zo ne on the dial indicates the
maximum engine speed which may be used briefly when the engine
is warm and after it has been run in properly. However, it is advisable
to change up a gear or move the se lector lever to “D” (or lift your
foot off the accelerator) before the needle reaches the red zone.
Caution
Never allow the rev counter needle ⇒page 11, fig. 2 to go into
the red zone on the dial for more than a very brief period: there is a
risk of damaging the engine. The start of the red zone on the dial is
different for some engine versions.
For the sake of the environment
Changing up a gear early will help you to save fuel and minimise
engine noise.

Technical data
If you press in the key
without pressing the clutch or brake pedal,
the ignition will be switched on or off. The steering lock is released
when the ignition is switched on. Diesel engines continue to be
automatically preheated.
The key can be removed only when the ignition is off. The key has to
be pressed in briefly to switch off the ignition. On vehicles with an
automatic gearbox, the selector lever has to be in position P.
Electrical components with a high power consumption are switched
off temporarily while you start the engine.
When starting from cold the engine may be a little noisy for the first
few seconds until oil pressure has built up in the hydraulic tappets.
This is quite normal and no cause for concern.
If the engine fails to start immediately, the starter will be switched
off automatically after a few seconds. Try to start the engine again.
Driving away from a standstill
On some vehicles, the engine revs are automatically increased
slightly as soon as you release the clutch. This helps you drive off
more smoothly.
Driver message in the instrument cluster display
Press brake pedal to start engine
This message appears on vehicles with an automatic gearbox if you
try to start the engine without first pressing the brake pedal.
Press clutch pedal to start engine
This message appears on vehicles with a manual gearbox if you try
to start the engine without first pressing the clutch pedal.
Engage N or P to start engine
This message will appear if you try to start the engine when the
selector lever of the automatic gearbox is not in P or N. Shift to P, otherwise vehicle can roll away. Doors do not lock if lever
is not in P.
or Please move selector lever to position P. Vehicle
cannot be locked.
For safety reasons, this message will appear and a warning buzzer
will sound if the selector lever of the automatic gearbox is not in
position P after you switch off the ignition. Put the se lector lever in
position P; otherwise the vehicle can roll away. If the lever is not in
position P you will not be able to lock the vehicle using the exterior
locking switch on the door hand le or the remote control key.
Steering lock
The steering is locked when the key is not in the ignition. The
steering lock acts as a theft deterrent.
WARNING
•
Always take the key with you when you leave the vehicle.
Otherwise the engine can be st arted or power-operated equip-
ment such as the electric windows can be used. This could result
in serious injury.
•
Never leave children or disabled people alone in the car. The
doors could be locked with the re mote control key and the occu-
pants could become trapped in the vehicle. The vehicle occupants
could be exposed to extremely high or low temperatures,
depending on the time of year.
•
Never remove the key from the ignition while the vehicle is
moving. The steering l ock could engage suddenly, and you would
not be able to steer the car.Caution
•
If a malfunction occurs in the electronic ignition lock, a flashing
symbol and the message Ignition lock defective will appear in the
instrument cluster display.
