Cockpit overview
If the light does not turn off after starting the
engine
or turns on while driving, this may indi·
cate that there is a malfunction in the eng ine. If
the indicator turns on , the catalytic converter
may be damaged.
Drive
with reduced engine performance (avoid
h ig h speeds for extended periods of time and/ or
fast acce leration) and have the malfunction cor­
rected. See an authorized Aud i dealer or author­
ized Audi Service Fac ility .
The electronic speed limiter may be faulty if the
indicator light turns on. For additional informa­
tion, refer to

The MIL indicator light may also turn on if the
fuel filler cap is not closed correctly
¢page 298.
On-Board Diagnostics
Fig . 24 Locat ion of Data Link Connector (D LC)
On-Board Diagnostics monitors the components
of your emission control system. Each monitored
component in your engine system has been as­
signed a code . In case of a malfunction, the com­
ponent w ill be identified and the fault stored 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 refuel ing, stop the
veh icle and make sure the fue l filler cap is prop­
erly closed (on ly vehicles with gasol ine engine)
¢page 298.
In order to make an accurate d iagnosis, the stor­
ed data can only be disp layed using specia l diag­
nostic equipm ent (ge ne ric scan tool for OBD) .

In order to connect the special diagnostic equip­
ment, push the plug into the Data Link Connector
(DLC). The DLC is located to the r ight of the hood
release
¢ fig. 24.
Your authorized Audi dea le r or qualified work­
shop can interpret the code and perform the nec­
essary repair.
_& WARNING
Do not use the diagnostic connector for per­
sonal use. Incorrect usage can cause malfunc­
tions, which can increase the risk of a colli­
sion!

result of heat buildup or if t he engine is a l­
ready warm and the engine compartment is
also heated by the sun's rays.
(D Note
I f the en gine has been under heavy load for
an e xtended per io d of t ime, heat builds up in
the engine compartment after the engine is
sw itched off and there is a risk of damagi ng
the engine . For this reason, let the eng ine run
at idle fo r approximately two minu tes before
shut ting it off .

A WARNING
-Always switch th e ignit ion off and take the
vehicle key with you when leav ing the veh i­
cle, eve n for a short per iod of t ime . This ap­
plies particularly when chi ld ren remain in
the ve hicle. Othe rwi se, children coul d sta rt
the engine, re le ase the p arki ng bra ke o r op­
er ate ele ctrica l equipmen t such as power
windows, which increases the risk of an acci ­
dent.
- When the vehicle is loc ke d , no one -particu ­
larly not children -sho uld rema in in the ve­
hicle . Locked doors make it more difficult
f or eme rgency workers to get into the vehi­
cle, which p uts lives at risk.
Starting from a stop
The hold assist function ensures that the parking
brake releases automatically when the vehicle
starts moving .
Stopping and setting the parking brake
" Pull th@(®) switch to s@t th @ parking bra k@ .
Starting and automat ically releasing the
parking brake
" When you pr ess t he accelerator pedal, the
par king b rake is autom atically released and
yo ur vehicle begins to move.
T he parki ng b rake c an be set if you must s top the
ve hicl e at a stop lig ht or in t raff ic. Th e ve hicle
does not have to be he ld with the brake pedal.
The parking brake e liminates the tendency to
creep when a selector lever position is engaged .
The par king b rake releases automatica lly and the
ve hicle beg ins to move as soon as you press the
accelerator pedal as usual.
Starting on hills
When starting on hills, hill start assist prevents
the vehicle from un intent iona lly rolling back. The
braking force of the parking brake does not re­
lease until the wheels bu ild up enoug h driving
force.
82
(D Tips
Fo r safety reasons, the par king brake only re­
l eases automatically when the drive r's door is
closed.
Starting to drive with a trailer
To prevent rolling back unintentionally on a hill,
do the following:
.. Keep the(®} switch pulled and press the acce l­
erator pedal. The parking brake remains set
and prevents the ve hicle from roll ing backwar d.
.. You can release the<®> switch once you a re sure
that you are giv ing enough driv ing force to the
wheels by pressing the accelerator pedal.
Depend ing on the weight of t he rig (vehicle and
trailer) and the steepness of the incline, you may
r oll backward as you start.
Emergency braking function
In the event that the standard brake system fails
or locks up.
.. To brake your veh icle in an eme rgency, pull the
<® > switch and ho ld it pulled.
.. As soon as you re lease the <®> switch or acceler-
ate, the braking stops.
P ulli ng and ho ld ing the C®l switch wh ile driving
the ve hicle activates the eme rgency brak ing func­
tion. The ve hicle brakes at all four wheels by acti­
vat ing the braking hydraulics . T he braking effect
i s sim ila r to mak ing a n emergency stop .
Q &
To reduce the risk of act ivat ing the emergency
braking by m istake, an audib le warning tone
(buzzer) sounds w hen the C®l switch is pulled.
Emergency b raking s tops as soon as th e<®>
switch is re leas ed or the ac celerator p eda l is

Driving with a trailer
General information
Your Audi was designed primarily for passenger
transportation.
If you plan to tow a trailer, please remember that
the additional load will affect durability, econo­my and performance.
Trailer towing not on ly places more stress on the
ve hicle, it also ca lls for more concentration from
the dr iver.
F or this reason, always follow the operating and
driving instructions provided and use common
sense.
Technical requirements
Trailer hitch
Use a weight-carrying hitch conforming to the
gross tra iler weight. The hitch must be suitab le
for your veh icle and tra iler and must be mounted
securely on the vehicle's chassis at a technically
sound
locat ion . Use on ly a trailer hitch with a re­
movable ba ll mount . Always che ck with the t rail ­
er hitch man ufac tur er to make s ure t hat you are
using the co rrect hi tc h.
Do not use a bumper hitch.
The hitch must be installed in such a way that it
does not interfere with the impact -absorbing
bumper system. No mod ificat ions should be
made to the vehicle exhaust and b rake systems .
Fr om t ime to t ime, che ck that all hitch mo unti ng
bol ts rem ain securely f aste ned.
W hen you are not tow ing a tra iler, remove the
tra ile r hitc h ba ll mount . This prevents the hit ch
from caus ing damage s hou ld your veh icle be
s truck from be hind ¢

Trailer brakes
If you r trailer is equipped with a brak ing system,
check to be su re that it conforms to all regula­
tions .

The t rai ler hydraulic bra ke system must not be
directly connected to the vehicle's hydraulic
bra ke system ¢&. .
Safety chains
Always use s afety chains be tween you r vehi cle
and t he tra ile r.
Trailer lights
Traile r lights must meet all regula tions . B e s ure
to check w ith your author ized Audi dealer for cor­
r ec t wir ing, swi tches and relays.
Mirrors
If you are unable to see t he traffic behind you us­
i ng t he regular outs ide mirrors, then yo u
