CD Note
- Auxiliary headlights and other accessories in
front of the cooling-air intake impair the
cooling effect of the coolant. This increases
the risk of the engine overheating during
high outside temperatures and heavy en-
gine load.
- The front spoiler also helps to distribute
cooling air correctly wh ile driving. If the
spo iler is damaged, the cooling effect will
be impai red and the risk of the engine over­
heating will increase. See an authorized
A udi dealer or authori zed Aud i Service Fa­
cility for assistance .
Tachometer
The tachometer displays the engine speed in rev ­
olutions per minute
(RPM).
You shou ld shift to the next lowest gear when
the eng ine speed is be low 1,500 RPM. The beg in­
ning of the red zone in the tachometer indicates
the maximum permissible engine speed for all
gears once the engine has been broken in and
when it is warmed up to operating temperature.
Before reaching this zone, you should sh ift into
the next highest gear, select the D selector lever position, or remove your foot from the accelera­
tor pedal.
CD Note
The needle in the tachometer @
Q page 8,
fig. 3 may only be in the red zone of the
gauge for a short t ime or the engine could be
damaged. The location where the red zone
begins va ries depend ing on the eng ine.
@) For the sake of the environment
Upshifting early helps you to save fuel and re­
duce operating noise.
Fuel level
The fuel leve l ind icator only ope rates when the
i gnit io n is switched on. The
tD Qpage 15
turns on if the reserve quant ity of fuel is reac hed.
In strum ents an d ind ic a to r ligh ts
The fue l tank capacity of your vehicle is listed in
the Techni cal Data section
Q page 216.
(D Note
Neve r dr ive until the tank is comp lete ly emp­
ty. The irregu la r supply of fuel that res ults
from that can cause engine misfires . Uncom­
busted fuel w ill then enter the exhaust sys­
tem. This can cause overheat ing and damage
to the catalyt ic converter.
Time/date display
You can switch between the quartz clock or the GPS controlled clock* depend ing on the vehicle
equipment. For mo re information, refe r to you r
MM I Operating Manual.
Outside temperature display
T he instrument cluster display shows the outside
temperature. At temperatures be low 42 °F ( +S
°C), a snowflake symbo l appears in front of the
temperature display.
If your vehicle is stationary or if you a re driving at
very low speeds, the temperature displayed may be slight ly higher than the actual temperature
o utside due to the heat radiating from the en ­
gine.
A WARNING
.-
Do not assume the roads are free of ice based
on the outside temperature d isplay. Be aware
that there may be ice on roads even when the
outside tempe rature is a round 42 °F (+5 °C)
a nd that i ce can increase t he risk of a cc idents.

You can set the units used for temperature,
speed and othe r measurements in the Info­
tai nment system.

consumption to zero (fuel shut-off during decel­
eration).
Shift efficiently
An effective way to save fuel is to upshift earlier .
Staying in a gear too long uses fuel unnecessari­
ly. Press down on the accelerator pedal slowly
and avoid "kick-down".
Avoid full acceleration
You should rarely travel at the maximum vehicle
speed. High speeds cause a disproportionately
high increase in fuel consumption, emissions and
traffic noise. Slower driving saves fuel.
Reduce idling time
There are benefits to stopping the engine, for ex­
ample when at railroad crossings or traffic lights
with longer red lights. Stopping the engine for
30-40 seconds already saves more fuel than the
amount of extra fuel needed to restart the en­
gine.
It takes a very long time in idle to warm the en­
gine up to operating temperature . Wear and
emissions are especially high in the warm-up
phase. Therefore, you should begin driving im­
mediately after starting the engine. Avoid high
RPMs while doing this.
Have maintenance performed regularly
By having maintenance performed regularly on
your vehicle, you can help to reduce fuel con­
sumption before you even start to drive. The maintenance condition of your vehicle not only
affects traffic safety and long-term value but al­
so impacts
fuel consumption. A poorly main­
tained engine can lead to fuel consumption that
is 10% higher than normal.
Also check the
oil level when refueling. The oil
consumption
depends largely on the engine load
and speed . It is normal for the oil consumption
of a new engine to reach its lowest point only af­
ter a certain amount of use. Therefore, the oil
consumption can only be properly judged after
approximately 3,000 miles (5,000 km) have been
driven.
Driving
Fewer short trips
The engine and catalytic converter have to reach
their optimal
operating temperature to reduce
fuel consumption and noxious emissions effec­
tively.
Just after starting, a cold engine in a mid-size car
only achieves a fuel economy of 6-8 mpg
(30-40 l/100 km). After about a half a mile, fuel
economy climbs to 12 mpg (20 l/100 km). After
about 2.5 mi
(4 km), the engine is at its proper
operating temperature and fuel economy has
reached a normal level. So you can see that you
should avoid short trips whenever possible .
The
outside temperature is also critical in this re­
gard. Your car consumes more fuel in the winter
than in the summer.
@ Note
Do not leave engine idling unattended after
starting. If warning lights should come on to indicate improper operation, they would go
unheeded. Extended idling also produces
heat, which could result in overheating or
other damage to the vehicle or other proper­
ty.
(D Note
- Have your vehicle maintained properly and
in accordance with the service recommenda­
tions in your Warranty & Maintenance book­
let. Lack of proper maintenance as well as
improper use of the vehicle will impair the
function of the emission control system and could lead to damage.
- Do not alter or remove any component of
the Emission Control System unless ap­
proved by the manufacturer.
- Do not alter or remove any device, such as
heat shields, switches, ignition wires,
valves, which are designed to protect your
vehicle's Emission Control System and other
important vehicle components .

Driving Emergency mode
Applies to: ve hicles w ith a utomat ic t ransm iss io ns
In the event of a system malfunction, there is an
emergency program.
If all of the selector lever positions are highligh t­
ed with a light background in the instrument
cluster display, there is a system malfunction and
the S tronic transmission is running in the emer­
gency program. The vehicle can still be driven in
emergency mode, but only with reduced speed
and not in all gears. In some cases, the vehicle
cannot drive in reverse.
@) Note
If the transmission runs in emergency mode,
drive to an authorized Audi dealer or author­
ized Audi Service Facility immediately to have
the malfunction corrected.

~ Add coolant mixed in the correct ratio
¢ page 166 up to the upper marking.
~ Make sure that the fluid level rema ins stable.
Add more coolant if necessary.
~ Close the cap securely.
Coolant loss usually indicates there is a leak. Im­
mediately drive your vehicle to an authorized
Audi dealer or authori zed Audi Service Facility
and have the cooling system inspected. If the
cooling system is not leaking, a loss can come
from the coolant boiling through overheating
and be ing pushed out of the cooling system.
.&, WARNING
The cool ing system is pressu rized and can be­
come very hot. To reduce the r is k of burns
from hot coolant :
- Do not open the coo lant expansion tank cap
when the engine is hot. This increases the risk of burns.
- Stop the engine and allow it to cool.
- Protect your face, hands and arms from es -
caping coolant and steam by covering the
coolant tank cap with a large, thick cloth .
- T urn the coo lant tank cap co unterclo ckwise
slowly and keep light pressu re on the cap .
- T o reduce the risk of burns , do not allow any
antifreeze o r coolant to drip onto the ex­
haust system or hot engine components.
T he ethylene glycol in engine coolant can
catch fire under certain circumstances .
- T he coo lant add itive and the coolant can be
dangerous to your health . For this reason,
keep the coolant in the original container
and away from children. There is a risk of
poisoning.
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of injury .
Do not add coolant if the expansion tank is
empty. Air could enter the cooling system and
damage the engine. If this is the case, do not
cont inue driv ing . See an authorized Audi deal -
Check ing and Filling
er or authorized Aud i Service Facility for assis ­
tance .
- Before the start of winter, have your author­
ized Aud i dea ler or a uthorized Audi Serv ice
Facility check if the coolant additive in your
vehicle matches the percentage appropriate
for the climate. This is especially important
when driving in colder climates.
- If the appropr iate coo lant add itive is not
availab le 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 m ixtu re ratio with the
specified coolant add it ive as soo n as poss i­
ble .
- Only refill w ith new coolant.
- Radiator sealant must not be mixed with
the coolant .
Radiator fan
T he radiator fan switches on automatically by it ­
self.
An auxiliary e lectr ic radiator fan switches on and
off depend ing on coolant temperature and other
vehicle operating conditions.
After you switch the engine off, the auxiliary fan c a n continue running for up to 10 m inutes - even
with the ignition off . It can even switch on aga in
later by itself ¢.& , if
- the temperature of the engine coolant rises due
to the heat build-up from the engine in the en­
gine compartment, or
- the engine compartment heats up bec ause the
veh icle is parked in in tense sunlight.
.&, WARNING
--
- To reduce the r isk of personal injury never
touch the radiator fan .
- The auxiliary e lectr ic fan is temperature
controlled and can switch on s uddenly even
when the engine is not runn ing .
- The auxiliary radiator fan sw itches on auto ­
mat ica lly when the eng ine coolant reaches a
certa in temperature and will continue to run
until the coolant temperature d rops .
