With the engine running
Although electrical energy is generated when
the vehicle is being driven, the battery can be
come discharged. This happens most ly when
litt le energy is being generated and a great
deal consumed and the battery's state of
charge is not optimal.
To bring the energy balance back into equili
brium, consumers which require especia lly
large amounts of energy are temporarily cut
back or switched off. Heating systems in par
ticular requ ire a great deal of energy. If you
notice, for example, that the heated seats* or
the heated rear window are not heating, they h ave been temporar ily cut back or switched
off. These systems will be available again as
soon as the energy ba lance has been restored.
You will also notice that engine idle speed has
been increased slightly. This is normal and not
a cause for concern . By increasing engine idle
speed the additional energy required is gener
ated and the battery is charged .
Driver notification in the instrument
cluster display
If battery power drops into the range where it
can limit the ab ility of the engine to start, th is
is shown in the instrument cluster display
with the following driver message:
(•) Low battery charge: battery will be
charged while driving
This notification reminds you that the starting
capability of the engine may be limited. As
soon as you start driving again, the battery
will be recharged and the notification will go
out.
Driver notification appears and goes out
again
If th is driver notification appears after the ig
nition is turned on or while driving and it goes
out again after a wh ile, the battery has been
adequately recharged.
Intelligent technology 233
Driver notification appears and does not
go out again
If this driver notification appears after the ig
nition is turned on or whi le driving and does
not go out again, the battery's state of charge
is not in the optimal range. Starting ab ility is
restricted . Have the battery checked as soon
as possible by an authorized Aud i dealer or
qualified workshop.

Catalytic converter
Applies to vehicles: with gasoline engine
It is very important that your emission control system (catalytic converter) is function
ing properly to ensure that your vehicle is run
ning in an environmentally sound manner .
... Always use lead-free gasoline¢ page 256,
Gasoline .
... Never run the tank down all the way to
empty .
... Never put too much motor oil in your en-
gine
¢ page 270, Adding engine oil~-
.,. Never try to push- or tow-start your veh icle.
The catalytic converter is an eff icient "clean
up" device built into the exhaust system of
the vehicle. The catalytic converter burns
many of the poll utants in the exhaust gas be
fore they are released into the atmosphe re.
The exclusive use of unleaded fuel is cr it ically
i mportant for the life of the cata lytic convert
e r and proper fu nctioning of the engine.
A WARNING ,~
- Do not park or operate the veh icle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fuel spill or other material which can
cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exhaust
man ifold, exhaust p ipes, catalytic con
verter or heat shie lds . During driving, the
substance used for undercoating could
overheat and cause a fire.
{[) Note
-Be aware that just one tank fi lling with
le aded fuel will already seriously de
grade the performance of the catalytic
conve rter .
- Do not exceed the correct engine oil level
¢ page 270.
-Do not drive until the fuel tank becomes
completely empty. The eng ine could mis
fire . U nburned fuel could a lso get into
Dri vin g and en vironm ent 235
the exhaust system and this cou ld cause
the catalytic converter to overheat .
- Do not turn off the igni tion while the ve
hicle is moving.
- Do not con tinue to ope rate your veh icle
unde r these conditions, as othe rwise fuel
can reach the catalytic converter. This
co uld result in overheating o f the con
verter, requir ing its replacement.
- To assure efficient operation of the Emis
sion Control System:
- H ave your vehicle maintained prope rly
and in accordance w ith the se rv ice rec
ommendat ions in you r Warranty &
M aintenance boo klet.
- L ack of prope r maintenance as we ll as
improper use of the vehi cle w il l impair
the function of the em ission contro l
system and could lead to damage .
@ For the sake of the environment
Even when the Emiss ion Control System is
operat ing properly, the exha ust gas can
have a sul fur -li ke exhaust gas smell under
some operating states . This depends on
the sulfur content of the fuel being used .
Using a different brand of fue l may help,
or f illing the tank with lead-free super
grade gasoline .
Diesel particulate filter
Applies to vehicles : with diese l eng ine
The diesel part iculate filter filters nearly all of
the soot particles out of the exhaust . The fil
ter cleans itself automat ica lly under normal
driv ing cond itions . If the filter ca nnot clean it
self (for example, because you a re o nly dr iving
short distances), the fi lter becomes clogged
with soot and the

Trailer towing weights
With a factory-installed trailer hitch, the
maximum permissible trailer weight is 6,615
l bs (3,000 kg) . Th e maximum permissible un
braked trailer weight is 1,650 lbs (750 kg).
With an
aftermarket trailer hitch, the maxi
m um permissible trailer weight is 5,512 lbs
(2,500 kg) . These specifications apply when
driving on roads having an incline of less than
12%.
Permissible tongue load
F or best vehicle handling under these
changed condit ions, adjust the trailer load so
that the tongue load is at the maximum al
lowable or slightly lower . You can get an ap
prox imation of the tongue load w ith a bath
room scale or you can measure the load at a
trucking company or weighing station .
With a
factory-installed trailer hitch, the
maximum permissible load on the ball h itch may not exceed 662 lbs
(300 kg). With an
af
termarket
trailer hitch, the maximum permis
s ib le load on the ba ll hitch may not exceed
551 lbs (250 kg). It is recommended to use
the maximum permissible load.
Trailer load distribution
Be sure the load in the trailer is held secure ly
in place to prevent it from shifting forward,
backward or sideways.
Never allow a passenger to ride in a trailer
¢&. in Driving instructions on page 243.
Ball mount
The trailer hitch may only be used w ith suita
ble ball mount and ball¢
fig. 233. In stalla
tion of the hitch ball must be carried out in ac
cordance with the manufac turer's instruc
tions. At the height dimension of 1.5 in
(38.5 mm) a tolerance of +/- 0.5 in (12. 7 mm)
is permissib le.
Engine cooling system
Towing a trailer makes the engine work ha rd
er . It is important that the cooling system's
performance is up to the additional load .
Make sure that the cooling system has enough
fluid .
Tire pressure
When towing a trailer, infla te the tires of your
vehicle to the cold tire pressu re listed under
" Full l oad" on the tire pressure label. The tire
pressure label is located on the driver's side B
pillar . Inflate trailer tires to trailer and tire
manufacturers' spec ificat ions .
Lights
The headlight settings shou ld be checked with
the trai ler attached before driving
off. Check
to make sure both vehicle and trailer lights
are working properly.
Safety chains
Be sure trailer safety chains are properly con
nected from the trai ler to the h itch on the ve
hicle. Leave enough slack in the chains to per
mit turning corners. When you install safety
IJ,,

chains, make sure they will not drag on the
road when you are driving.
The cha ins shou ld cross under the trai le r
tongue to prevent it from dropping in case of
separation from the hitch.
(D Note
If you are going to tow a trailer, you must
activate the trailer operation mode
¢page 159, Towing a trailer.
Driving instructions
Driving with a trailer always requires extra
core and consideration.
To obtain the best poss ible handling of vehicle
and traile r, p lease note the following:
.,. Do not tow a loaded tra iler whe n your car it
self is not loaded.
.,. Be especially careful when passing other
vehicles .
.. Observe speed limits.
.. Do not d rive at the maximum permissible
speed.
.. Always apply brakes early.
.. Monitor the temperature gauge.
Weight distribution
Tow ing a loaded trai ler with an empty ca r re
sults in a high ly unstable distribution of
weight. If this cannot be avoided, drive at very
l ow speeds only to avoid the risk of losing
steering control.
A "balanced" rig is easier to operate and con
trol. This means that the tow vehicle should
be loaded to the extent possible and permiss i
ble, while keeping the trailer as light as possi
ble under the circumstances. Whenever possi
ble, transfer some cargo to the luggage com
partment of the tow vehicle wh ile observing
tongue load requirements and vehicle loading
considerations .
Speed
The higher the speed, the more difficult it be
comes for the driver to control the rig . Do not
drive at the maximum permissible speed. Re-
Trailer towing 243
duce your speed even more if load, weather or
wind conditions are unfavorable - particularly
when going downhill.
Red uce veh icle speed
immediately if the trail
er shows the slightest sign of sway ing.
Do not
try to stop the swaying by accelerating.
Observe speed limits. In some areas, speeds
f or vehicles towing trailers are lower than for
regular vehicles.
Always apply brakes early. When driving
downh ill, shift into a lowe r gear to use the en
gine braking effect to slow the vehicle. Use of
the brakes alone can cause them to overheat
and fail.
Coolant temperature
The coolant temperature gauge¢ page 10
must be observed carefully. If the need le
moves close to the upper end of the scale, re
duce speed immediately and/or turn off the
air conditioner.
If the coolant temperature warning light in
the instrument cluster starts flashing ., pull
off the road, stop and let the engine
idle for
about two minutes to prevent heat build -up .
A WARNING
Anyone not properly restrained in a mov
ing vehicle is at a much greater risk in an
accident. Never let anyone ride in your car
who is not properly wearing the restraints
prov ided by Audi .
Trailer towing tips
Important to know
-
Your vehicle handles differently when towing
a trai ler because of the additional weight and
different weight distr ibution. Safety, perform
ance and economy will great ly depend on how
carefully you load your trailer and operate
your rig.
Before you actua lly tow your tra iler, practice
turning, stopping and backing up in an area
away from traffic. Keep practicing until you
•
•

244 Trailer towing
have become comp lete ly familiar with the way
your vehicle-trailer combination behaves and responds.
Backing up is difficult and requires practice.
Backing up with a trai ler genera lly requires
steering action opposite to that when backing
up your veh icle without a trailer .
Maintain a greater distance be tween your ve
hicle and the one in front of you. You will need
more room to stop. To compensate for the
trailer, you will need a larger than normal
turning radius.
When passing, remember that you cannot ac
celerate as fast as you normally would be
cause of the added load. Make sure you have
enough room to pass . After passing, allow
plenty of room for your trailer before chang
ing lanes again .
Avoid jerky starts, sharp turns or rapid lane
changes.
- Do not tow a trailer during the break-in
period of your vehicle.
- If you tow a trailer, your Audi may re
quire more freq uent maintenance due to
the extra load
c> page 325.
Parking on a slope
Do not pork on a slope with a trailer. If it can
not be avoided, do so only after doing the fol
lowing:
When parking:
.. Apply the foot brake .
.. Have someone place chocks under both the
vehicle and the trai ler wheels .
.. With chocks in p lace, slowly re lease the
brakes until the wheel chocks absorb the
load .
.. Turn the wheels towards the curb .
.. Apply the parking brake .
.. Move the selector lever to
P.
When restarting after parking:
.. Apply the foot brake. ..
Start the engine.
.. Move the se lector lever to
D.
.. Release the parking brake and s low ly pull
out and away from the wheel chocks.
.. Stop and have someone retr ieve the wheel
chocks .
(D Tips
If you move the selector lever of the auto
matic transmission to
P before applying
the parking brake and before blocking the
wheels, you may have to use more fo rce

A WARNING
Improper refueling or handling of fuel can
cause fire, explosion and severe burns.
- Fuel is highly flammable and can cause
severe burns and other injur ies.
- Failure to shut the engine off wh ile refu
eling and/or to insert the pump nozzle
fully into the fuel filler neck could cause
fue l to spray out of filler neck or to over
f low. Fue l spray and overflowing fue l can
cause a fi re.
- Never use a cel lu lar telephone while re
fueling. The electromagnetic rad iation
can cause sparks that can ignite f uel va
pors and cause a fire.
- Never get back into your vehicle whi le re
fueling. If in exceptional circumstances
you must get back in your vehicle while
refueling, make certain that you close
the door and touch metal to discharge
stat ic electricity before touching the fill
er nozzle again. Static e lectricity can
cause sparks that can ignite fuel vapors re leased du ring refuel ing .
- Never smoke or have an open flame any

- For your safety, we strongly recommend
that you do not travel with a portable
fuel container in your vehicle. The con
tainer, full or empty may leak and could cause a fire, especially in a crash.
- If, under exceptional circumstances, you
must transport a portable fuel container,
please observe the following:
- Never fill a portab le fuel container
while it is anywhere in or on the vehicle
(for example, in the luggage compart
ment, or on the trunk). Static electrici
ty can build up while filling and can ig n ite fuel vapors causing a fire .
- Always place a portable fuel container
on the ground before filling.
-Always keep the fi ller nozzle complete
ly inside the portable container before
and during filling.
- If filling a portable container made of
metal, the filler nozzle must always be
in contact with the container. This will
help prevent static electricity from dis
charging and cause a fire .
- Never sp ill fuel inside the vehicle or
luggage compartment. Fuel vapors are
h ighly flammable.
- Always observe local and state/provin
cial laws regarding the use, storage
and transpo rtation of fuel conta iners.
- Make certa in the fuel container meets
industry standards (ANSI/ ASTM
F8S2-86).
@ Note
If any fuel has spilled onto the car, it
should be removed immed iately to prevent
damage to the paint .
@) For the sake of the environment
As soon as the correctly operated nozzle
sw itches off automatically for the first
time, the tank is full. Do not try to add
mo re fuel because fuel may spill out. In
add it ion, the expans ion space in the fuel
tank will be f illed -causing the fue l to overflow when it becomes warm and pol
lute the environment .
(D Tips
-Running your engine whi le refue lling
may cause vapors to escape or even
cause fuel to spi ll out of the tank. This
would then shut off the fue l nozzle be
fore the tank is full.
- Do not refuel your vehicle with the igni
tion turned on. The fuel gauge may oth
erwise not indicate the correct fuel level
after refuelling.
- Diesel vehicles* are equipped with a die sel misfueling protector. It allows the
vehicle to be fueled only with a diesel
fuel pump nozzle. A worn or damaged nozzle or a nozzle that is too small may
not be ab le to open the diesel misfueling
protector. If this is the case, try turning
the nozzle before insert ing it in the f uel
filler neck, use a different fuel pump or
see your authorized Audi dea ler or au
thorized repair facility for assistance.
