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
Audi dealer or authorized Audi Service Fa­
cility for assistance.
Tachometer
The tachometer displays the engine speed in rev­
olutions per minute (RPM) .
You should shift to the next lowest gear when
the engine speed is below 1,SOO RPM . The begin­
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 temperat ure.
Before reaching the red zone, you shou ld shift in­
to the next higher gear, choose the Dor S selec­
tor lever position, or remove your foot from the
accelerator pedal.
CD Note
The needle in the tachometer @Q page 8,
fig. 3 may only be in the red area of the gauge
for a short time or there is a risk of engine
damage.

On-Board Diagnostics
Fig. 5 Location o f Data Li nk Con necto r (OLC)
On-Board Diagnostics monitors the components
of your emission control system. Each monitored
component in your engine system has been as­
s igned a code. In case of a malfunction , the com­
ponent will be identified and the fault sto red as a
code in the control module memory.
The MIL light may also illuminate if there is a
leak in the on-board fuel vapor recovery system.
If the light illuminates after a refueling, stop the
vehicle and make sure the fuel f iller cap is prop­
erly closed (only vehicles with gasoline engine)
r::'.>page 153 .
In order to make an acc urat e diagnosis, the stor­
ed data can only be displayed using special diag­
nostic equipment (generic scan tool for 080).
In order to connect the special d iagnost ic equip­
ment, push the p lug into the Data Lin k Connector
(DLC). The DLC is located to the right of the hood

Trailer towing
Driving with a trailer
General information
Your vehicle is primarily intended for transport­ ing people and luggage . However, if you drive
with a trailer , follow the technical requirements,
the operation and driving tips, and the legal reg­
ulations.
Driving with a trailer affects the vehicle's fuel
consumption, performance and wear.
It also re­
quires higher concentration from the driver.
A WARNING
Do not transport any people in a trailer due to
the risk of fatal injury.
Technical requirements
Certain requirements must be met when towing
a trailer.
Trailer hitch
Only use a trailer hitch with a removable ball hitch mount and ball hitch. The trailer hitch must
be permitted for the vehicle , the trailer and the
permitted total weight of the trailer being
pulled. Above all, it must be securely and safely
attached to the vehicle trailer.
Never mount a trailer hitch on the bumper. The
trailer hitch must be mounted in a way that does
not impair the function of the bumper. Do not
make any changes to the exhaust system and the
brake system.
Check regularly if the trailer hitch is securely mounted. Always follow the instructions given by
the trailer hitch manufacturer.
Trailer brakes
If the trailer has its own brake system, then fol­
low the manufacturer specifications. However,
the brake system on the trailer must never be
connected to the vehicle brake system.
Trailer towing
Engine cooling system
Driving with a trailer means a higher load on the
engine and the cooling system. The cooling sys­
tem must be designed for additional load and
contain enough coolant
c::> (D .
A WARNING
-
-Never mount a "weight-distributing" or
"load-balancing" trailer coupler as the trail­
er hitch . The vehicle was not designed for
these types of trailer hitches . The trailer
hitch can malfunction and the trailer can
break off from the vehicle.
- If the trailer is equipped with electronic
brakes, these brakes cannot be activated by
a factory-installed control system, which in­
creases the risk of an accident.
- To reduce the risk of injury, always remove
the ball hitch mount if no trailer is mount­
ed.
(D Note
Longer inclines cannot be driven without a
suitable cooling system, especially if the out­
side temperatures are high. otherwise, this
increases the risk of engine damage.
' Operating instructions
Several things must be noted when towing a
trailer.
Towing capacity
The permitted towing capacity for trailers with­
out brakes is 1,650 lbs (750 kg).
The permitted towing capacity for trailers with brakes is 2,200 lbs (1,000 kg) .
These values apply to roads with up to 12% in­
cline.
Tongue weight
The maximum permitted tongue weight of the
trailer drawbar on the trailer hitch ball head may
not be exceeded. ..,.

-Fuel system damage and performance prob­
l ems resulting from the use of fuels differ­
ent from those specified are not the respon­
sibility of Audi and are not covered under
the New Vehicle or the Emission Control
System Warranties.
- If you experience a loss of fuel economy or
driveability and performance problems due
to the use of one of these fuel blends, we
recommend that you switch to unblended
fuel.
Gasoline additives
A majo r concern among many auto manufactur­
ers is carbon deposit build-up caused by the type
of gasoline you use.
Although gasoline grades d iffer from one manu­
facturer to another, they have certain things in
common. All gasoline grades contain substances
that can cause deposits to collect on vital engine parts, such as fuel injectors and intake valves . Al­
though most gasoline brands include additives to keep engine and fuel systems clean, they are not
equally effective.
Audi recommends using TOP TIER Detergent Gas­
oline . For more information on TOP TIER Deter­
gent Gasoline, please go to the official website
(www.toptiergas.com).
After an extended period of using inadequate
fuels, built-up carbon deposits can rob your en­ gine of peak performance.
(}) Note
-Damage or malfunction due to poor fuel
quality is not covered by the Audi New Vehi ­
cle Limited Warranty.

turn on.
If the central loc king system malf unc tions, the
f u e l filler door may emergency release
¢ page 155.
A WARNING
An improper fue ling procedure and improper
hand ling of fue l can lead to explosions, f ires,
severe bu rns and other injur ies.
- Do not smoke and keep away from open
flames.
- The ignition must be switched off when re­
fueling .
- Cell phones, radio devices and other radio
equipment should always be switched
off
when refueling. Electromagnet ic rays cou ld
cause sparks and start a fire.
- If you do not insert t he fue l pump nozzle a ll
the way into the filler tube, then f ue l can
leak out. Spilled fuel can ignite and start a
fire .
- Never get into the vehicle when refueling. If
there is an exceptional situation where t he
vehicle must be entered, close the door and
touch a metal surface before touching the
fuel pump nozzle agai n. This will reduce the
r isk of e lectros tat ic discharge t hat can ca use
flying spar ks. Sparks can start a fire when
ref ue ling.
A WARNING
We recommend that you do not t ransport any
fuel containers in the vehicle . Fuel could leak
out of t he container and ignite, especially dur-
l) Market -s pecific
154 ing an accident. Th
is can ca use explos ions,
f ires and injuries.
- If you must transport fuel in a fue l contain­
er, p lease note the following:
- Always place a fue l co nta iner on the
ground befo re fil ling . Neve r fill the fuel
contai ne r with fuel whi le i t is in o r o n the
vehicle. Elect rostatic charge can oc cu r
while refueling and the fuel vapo rs could
ignite.
- Fo r fuel con tai ners made o f me tal, the
fuel p ump nozzle must a lways maintai n
contact with the container to reduce the
risk of stat ic charge.
- Insert the fuel pump nozz le as far as pos­
sible into the f iller opening wh ile refuel­
ing .
- Fo llow lega l req uirements when using,
stor ing and transporting fuel conta iners .
- Make su re t hat the fuel container meets
the i nd ustry standards, for example ANSI
or ASTM F852-86.
(D Note
- Remove fue l tha t has overflowed onto any
vehicle components immediately to reduce
the risk of damage to the vehicle.
- Never drive unt il the fuel tan k is com plete ly
empty . The i rreg ular s upply of fue l that re­
sults from that can cause eng ine misfires .
Uncombusted fuel will ente r the exhaust
system and increase the risk of damage to
the catalytic converter .
(® For the sake of the environment
Do not overfill the fuel tank, otherwise fuel
can leak out when the veh icle is warming up.
(D Tips
The fuel filler door o n your veh icle does not
