A WARNING
-Always observe the warning in¢ page 195,
before open ing the hood and check ing the
engine coolant level.
- Never open the engine hood if you see or
hear steam, or if you see engine coolant
dr ipping from the engine compartment. You
cou ld burn yourself. Let the eng ine cool off
first so that you cannot hear o r see any
steam o r engine coo lant.
0 Note
- Mount ing additional lights or accesso ries in
fron t of the a ir inlets reduces the cooling ef­
fect of the radia to r. A t high outside temper­
atu res or high e ngine load, the eng ine could
overheat.
- The front spo iler has been designed to prop­
erly distribute the cooling air when the veh i­
cle is moving. If the spo iler is damaged, this
could reduce the cooling effect and the en­
gine could then overheat. Ask your author­ ized Audi dealer for assistance.
Tachometer (engine rev counter)
The tachometer indicates the engine RPM (revo­
lutions per minutes).
If engine RPM drops be low 1,5 00, you should
downshift to the next lower gea r. T he red area at
the end of the scale indicates max imum permis­
sible eng ine RPM after the break-in period . Be­
fore reachi ng this area, move the selector lever to
position D/S or ease your foot off the accelerator
pedal.
(D Note
The tachometer needle@¢ page 10, fig. 3
should o nly briefly be in the red zone: you
co uld damage your eng ine! The beginn ing of
the r ed zone varies depending on the engine.
@ For the sake of the environment
Upshift ing early saves fuel and reduces eng ine
noise .

Automatic transmission
This prevents too much stress from being placed
on the locking mechanism.
Vehicles with multitronic transmission: Your vehi­
cle is equipped with
hill hold assist allowing you
to start while on an incline. The system is activat­
ed when the brake pedal is pressed down and
held
for a few seconds. The brake pressure will
hold for
a momen t after the brake pedal loosens
t o preven t the vehicle from rolling backwards
while starting up .
A WARNING
- The vehicle can also roll when the engine is
stopped .
- Unintended vehicle movement can cause se­ rious injury .
- Never leave your vehicle with the engine
running while in gear.
If you must leave your
vehicle when the engine is running, activate
the parking brake and move the selector lev­
er to
P.
-Power is still transmitted to the wheels
when the engine is running at idle. To pre­
vent the vehicle from "creeping", you must
keep your foot on the brake when the engine
is running and the selector lever is in 0/5 or
R or "tiptronic" mode is selected.
- Do not press the accelerator pedal when changing the selector lever position while
the vehicle is stationary and the engine is
running .
- Never shift into R or P while driving.
- Before driving down a steep slope, reduce
your speed and shift into a lower gear with
"tiptronic".
- Do not ride the brakes or press the brake
pedal too often or too long when driving
down a hill. Constant braking causes the
brakes to overheat and substantially re­
duces braking performance, increases brak­
ing distance or causes complete failure of
the brake system .
- To prevent the vehicle from rolling back
when stopping on inclines, always hold it in
place with the brake pedal or parking brake.
- Never hold the vehicle on an incline with a
slipping clutch. The clutch opens automati-
86
cally when it becomes too hot from the
overload. An indicator lamo
[ O ] illuminates
and a driver message appears
¢ page 88
when the clutch is overloaded.
- If the engine must remain running, never
have any driving position engaged when
checking under the hood . Make sure these­
lector lever has securely engaged and is
locked in P with the parking brake set
¢ page 195. Otherwise, any increase in en­
gine speed may set the vehicle in motion,
even with the parking brake applied.
(D Note
- 5 tronic- and tiptronic transmission: When
stopping on an incline, do not try to hold
the vehicle in place by pressing the accelera­
tor pedal while a driving gear is selected.
This can cause the transmission to overheat
and can damage it. Activate the parking
brake or press the brake pedal to prevent
the vehicle from rolling.
- 5 tronic- and tiptronic transmission: Allow­
ing the vehicle to roll when the engine is
stopped and the selector lever is in N will
damage the transmission because it is not
lubricated under those circumstances .
(D Tips
For safety reasons, the parking brake is re­
leased automatically only when the driver's
safety belt is engaged in the buckle .
· Hill descent control
App lies to vehicles: wit h mult itronic/S tronic/tiptronic
The hill descent control system assists the driver
when driving down declines.
Hill descent control is activated when the selec­
tor lever is in 0/5 and you press the brake pedal.
The transmission automatically selects a gear
that is suitable for the incline. Hill descent con­
trol tries to maintain the speed achieved at the
time of braking, within physical and technical
limitations.
It may still be necessary to adjust the
speed with the brakes. .,.
