Coolant temperature
indicator
The coolant temperature display @ > page 10,
fig. 3 only functions when the ignition is switch-
ed on. To reduce the risk of engine damage,
please observe the following notes about the
temperature ranges.
Cold range
If only the LEDs at the bottom of the gauge turn
on, the engine has not reached operating tem-
perature yet. Avoid high engine speeds, full accel-
erating and heavy engine loads.
Normal range
The engine has reached its operating tempera-
ture once the LEDs up to the center of the gauge
turn on. If the | indicator light in the instru-
ment cluster display turns on, the coolant tem-
perature is too high > page 17.
@) Note
— Auxiliary headlights and other accessories in
front of the air intake impair the cooling ef-
fect of the coolant. This increases the risk of
the engine overheating during high outside
temperatures and heavy engine load.

Instrument cluster

— The front spoiler also helps to distribute
cooling air correctly while driving. If the
spoiler is damaged, the cooling effect will
be impaired and the risk of the engine over-
heating will increase. See an authorized Au-
di dealer or authorized Audi Service Facility
for assistance.
Tachometer
The tachometer (2) > page 10, fig. 3 displays the
engine speed in revolutions per minute (RPM).
The beginning of the red zone in the tachometer
indicates the maximum permissible engine speed
for all gears once the engine has been broken in.
Before reaching the red zone, you should shift in-
to the next higher gear, choose the "D" or "S" se-
lector lever position, or remove your foot from
the accelerator pedal.
Engine speed limitation
Applies to: vehicles with engine speed limitation
If the BB indicator light turns on, the engine will
be automatically limited to the RPM displayed in
the instrument cluster. This protects the engine
from overheating.
The engine speed limitation deactivates once the
engine is no Longer in the critical temperature
range and you have released the accelerator ped-
al once.
If the engine speed limitation was activated by
an engine control malfunction, the B indicator
light also turns on. Make sure the engine speed
does not go above the speed displayed, for exam-
ple when downshifting. Drive to an authorized
Audi dealer or authorized Audi Service Facility im-
mediately to have the malfunction corrected.
@) Note
The needle in the tachometer may only be in
the red area of the gauge for a short period of
time before there is a risk of damaging the
engine. The location where the red zone be-
gins varies depending on the engine.
Odometer

- = .
Fig. 4 Instrument cluster: odometer and reset button
The trip odometer and odometer are displayed in
the status line ©) > page 10, fig. 3.
The trip odometer shows the distance driven
since it was last reset. It can be used to measure
short distances. The odometer shows the total
distance that the vehicle has been driven.
Resetting the trip odometer

> Press the reset button [9-9] on the instrument
cluster. The trip odometer will be reset to zero.
@) Tips
Distances are displayed in mi (miles) or km
(kilometers).

Outside temperature
display
The outside temperature is displayed in the sta-
tus line ® page 10, fig. 3.
If your vehicle is stationary or if you are driving at
very low speeds, the temperature displayed in
the instrument cluster may be slightly higher
than the actual temperature outside due to heat
radiating from the engine.
At temperatures below 41 °F (+5 °C), a snowflake
symbol appears in front of the temperature dis-
play > A.

ZA\ WARNING
Do not assume the roads are free of ice based
on the outside temperature display. Be aware
that there may be ice on roads even when the

11

Instrument cluster

outside temperature is around 41 °F (+5 °C)
and that ice can increase the risk of accidents.


Fuel level
The display @ > page 10, fig. 3 only works when
the ignition is switched on. When the display has
reached the reserve mark, a red LED turns on and
the i indicator light turns on > page 19.
For
the tank capacity in your vehicle, refer to the
Technical Data > page 290.
@ Note
Never drive until the tank is completely emp-
ty. The irregular supply of fuel that results
from that can cause engine misfires. Uncom-
busted fuel will then enter the exhaust sys-
tem. This can cause overheating and damage
to the catalytic converter.

for the climate. This is especially important
when driving in colder climates.
— If the appropriate coolant additive is not
available in an emergency, do not add any
other additive. You could damage the en-
gine. If this happens, only use water and re-
store the correct mixture ratio with the
specified coolant additive as soon as possi-
ble.
— Only refill with new coolant.

>» Switch the ignition off.
> Allow the engine to cool.
> Place a large, thick cloth over the coolant ex-
pansion tank cap and unscrew the cap counter-
clockwise > A\.
> Read the coolant level using the coolant level
float. The coolant level float may only stick out
over the edge of the coolant expansion tank a
maximum of 0.39 in (1 cm) when the engine is
cool.
Adding coolant
If you must add coolant, use a mixture of water
and coolant additive. Mixing the coolant additive
with distilled water is recommended.
> Add coolant in the correct mixture ratio
=> page 236 until the dipstick is no more than
0.39 in (1 cm) above the edge of the coolant
expansion tank.
> Make sure that the fluid level remains stable.
Add more coolant if necessary.
> Close the cap securely.
Coolant loss usually indicates that there is a leak.
Immediately drive your vehicle to an authorized
Audi dealer or authorized Audi Service Facility
and have the cooling system inspected. If the
cooling system is not leaking, coolant loss can re-
sult from the coolant boiling due overheating
and then being forced out of the cooling system.

ZA\ WARNING
— The engine compartment in any vehicle can
be a dangerous area. Stop the engine and al-
low it to cool before working in the engine
compartment. Always follow the informa-
tion found in > page 229, General informa-
tion.
— Never open the engine compartment lid if
you can see or hear steam or coolant escap-
ing from the engine compartment. This in-
creases the risk of burns. The cooling system
