Trailer mode Driving with a trailer
General information
Your Audi was designed primarily for passenger
transportation.
If you plan to tow a tra iler, p lease remember that
the additiona l load will affect durability, econo­
my and performance .
T railer towing not on ly places more stress on the
vehicle, it also calls for more concentrat ion from
the driver .
F or this reason, a lways fo llow the operating and
d riving instructions provided and use common
sense.
Technical requirements
Traile r hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suitable
for your vehicle and trailer and must be mounted
securely on the veh icle 's chassis at a technically
sound
location . Use on ly a tra iler hitc h with a re­
movable ba ll mou nt. Always chec k w ith the t ra il­
e r hitch m anu fac tur er to make sure that you a re
using the co rrec t hitch.
Do not use a bumper hitch .
The hitch must be installed in such a way that it
does not in terfere with the impact-absorbi ng
bumper system. No mod ificat ions should b e
mad e to the vehicle exhaust and brake systems .
Fr om time to t ime, c hec k t hat a ll h itch mou nti ng
bo lts remain sec urely fastened .
When you are no t tow ing a trailer,
remove the
trai ler hitch ball mount . Th is prevents the hitc h
fr om caus ing damage should you r vehicle be
s truck from behind¢,&. .
Trailer brakes
If yo ur tra iler is equipped w it h a braking system,
check to be s ure that it conforms to all regu la­
tions.
Trailer mode
T he trailer hyd raulic brake system must not be di ­
rect ly connected to the ve hicle's hydraulic b rake
system ¢.&. .
Safety chains
Alw ays use s afety ch ains be tween your ve hicle
and t he tra ile r.
Trailer lights
Tra ile r li ghts must meet all regulations. Be sure
to check w it h your author ized Audi deal er for cor­
r e ct w iring, sw itches, and relays.
Mirrors
If you are unable to see the traffic behind you us­
i ng the regular o uts ide mirrors, then you
must in ­
sta ll extended mirrors .
It is importa nt that you
always have clea r vision to the rea r.
_&. WARNING
- I f a trai ler has elec trical brake s please note
th at these b ra kes are not acti va ted by the
factory -fitted contro l unit -ris k of acci dent!
- After removing the t railer hi tch, do n ot store
it in your vehicle . In case o f su dden braking,
the hi tch could fly forward and injure you or
your passe ngers.
Operating instructions
Maximum traile r weight
A trai ler for you r vehicle is limited to a typical
class 1 or class 2 trailer.
Trailer load distribution
B e sure the load in the t ra iler i s held secure ly in
pla ce to prevent it from sh ifting forw ard , back ­
war d or sideways .
Never allow a passenger to ride in a trailer¢.&.
in Driving in struc tion s on page 182.
Engine cooling system
Towing a trailer makes the engine work harder . It
is important that the cooling system's pe rform­
ance is up to the additional load . Ma ke s ure that
t h e coo ling system has enoug h fluid.

Trailer mode
Tire pressure
When tow ing a trailer, inflate the tires of your ve­
hicle to the cold tire pressure listed under " Full
load" on the label located on the driver's side B ­
pillar (visible when the door is open). Inflate
trailer tires to trailer and tire manufacturers'
specifications.
Lights
The headlight settings should be checked with
the trailer attached before driving off . Check to
make sure both vehicle and trailer lights are
working properly.
Safety chains
Be su re trailer safety chains are properly connect­
ed from the trailer to the hitch on the vehicle.
Leave enough slack in the chains to permit turn­
ing corners. When you install safety chains, make
sure they will not drag on the road when you are
driving.
The chains shou ld cross under the trai ler tongue
to prevent it from dropping in case of separation
from the hitch.
Driving instructions
Driving with a trailer always requires extra care
and consideration.
To obtain the best possible handling of vehicle
and trai ler, please note the following:
.. Do not tow a loaded trailer when your car itself
is not loaded .
.. Be especia lly careful when passing other
vehicles.
.. Observe speed limits.
.. Do not drive at the maximum permissible
speed .
.. Always apply brakes early.
.. Monitor the temperature gauge.
Weight distribution
Towing a loaded trai ler with an empty car results
in a highly unstable distribution of weight. If this
cannot be avoided, drive at very low speeds only
to avoid the risk of losing steering control.
182
A "balanced" rig is easier to operate and contro l.
This means that the tow vehicle shou ld be loaded
to the extent possible and permissib le, wh ile
keep ing the trailer as light as possible under the
c ir cumstances. Whenever poss ible, transfer
some cargo to the luggage compartment of the
tow veh icle while observing tongue load require­
ments and vehicle load ing considerat ions .
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. Reduce
your speed even more if load, weather or w ind
cond it ions are unfavorab le - particularly when
go ing downh ill.
Reduce veh icle speed
immediately if the trailer
shows the slightest sign of swaying.
Do not try
to stop the swaying by accelerating.
Observe speed limits. In some areas, speeds for
vehicles towing tra ilers are lower than for regular
vehicles.
Always apply brakes early. When dr iving down­
hill, shift into a lower gear to use the engine
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 needle moves close
to the upper end of the scale, reduce speed im­
med iately 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 m inutes to prevent heat build-up .
&_ WARNING
Anyone not properly restrained in a moving
vehicle is at a much greater risk in an acci­
dent. Never let anyone ride in your car who is
not properly wearing the restraints provided
by Audi.

Checking and F ill in g
Using the proper engine o il is important for the
functionality and service life of the engine. Your
engine was factory-fi lled w ith a high-quality o il
which can usually be used throughout the ent ire
year.
@) Note
Your L imited New Vehicle Warranty does not
cover damage or malfunctions due to failure
to follow recommended ma intenance and use
requ irements as set forth in the Audi Ow ne r's
Manual and Wa rranty
& Ma intenance booklet .
- Use only a high quality eng ine oil t hat ex-
pressly comp lies w ith the Audi o il quality
standard specified for your vehicle's e ngine .
Using a ny other oil can cause se rious engine
damage.
- Do not mix any lubricants o r othe r addit ives
i nto the engine oil. Doing so can cause en ­
g ine damage.
(D Tips
If you need to add oil and there is none availa­
ble that meets the Audi o il quality standard
y o ur eng ine requires, you m ay add a total of
no more than 0.5 quart/li ter o f a h igh-quali ty
"synthet ic"oil that meets the fo llowing speci ­
fications .
- V ehicles wi th gasoline engine: AC EA A3 o r
API SM with a viscosity grade of SAE 0W- 30,
SAE SW -30 or SAE SW-40 .
- Fo r more informa tion abo ut engine oi l that
has been approved for your vehicle, please

or Audi Customer Relations at
1 (800) 822-2834 or visit o ur web site at
www .aud iusa.com or www .aud icanada .ca .
Engine oil consumption
The engine in your vehicle depends on an ade­
quate amount of oil to lubricate and cool all of
its moving parts .
In order to provide effective lubrication and cool­
i n g of in ternal engine components, all interna l
combustion engines consume a certai n amount
of oil. O il consumption var ies from engine to en­
g ine and may change significant ly ove r the life of
198
the engine. Typically, eng ines with a specif ied
break-in period (see
¢ page 177) consume mo re
o il dur ing the b reak -in per iod than they consume
after oil consumption has stabili zed.
U nder normal cond itions , the rate of oi l con ­
s u mption depends on t he qu ality and viscosity of
the oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient tem ­
perature and road condit ions. Further factors are
the amount of o il di lution from water condensa ­
tion or fuel residue and the ox idat ion level of the
o il. As any engine is s ubject to wear as mileage
builds up, t he oil consump tion may inc rease ove r
t ime unt il rep lacement of wo rn component s may
become necessary.
With a ll these va riab les coming into p lay, no
sta ndard ra te of oil consumpt ion can be estab­
li shed or spe cified . There i s no altern ative to reg­
u la r and freq uent checking o f the oil leve l, see
Note .
If the yellow e ngine oi l leve l wa rning symbo l El
in the instr ument cluster lights up, yo u should
chec k the o il level as soon as possible
¢ page 199 . Top off the oil at your ear liest con ­
venience ¢page 199.
A WARNING
Before you chec k anything in the eng ine com­
partment, always read and heed a ll WARN­
INGS¢ .&. in Working in the engine compart­
ment on page 195 .
@ Note
Driving with an insufficient oi l level is likely to
cause severe damage to the engine.
(D Tips
- The oil pressu re warning display. is not
an indicator of the oil level. Do not rely on
it . Instead, check the oil level in your en­
gine at regular intervals, preferably each
time you refuel, and always before going on a long trip.
- If you have the impression yo ur engine con­
sumes excessive amounts of oil, we r ecom-
mend that yo u consult an au tho rized Audi .,.

Disconnecting the battery terminals
Some vehicle functions (power window regula­
tors , for example) are lost if the battery termi­
nals are disconnected. These functions have to be
re learned after th e battery terminals are con­
nected again. To prevent this, the batte ry should
only be disconnected from the ve hicle electrical
system when absolutely necessary for repairs.
Vehicles not driven for long periods
If you do not drive your vehicle over a period of
several days or weeks, e lectrica l components are
gradually cut back or switched off. This reduces
energy consumption and maintains starting ca­ pability over a longer period
c:> page 175 .
Some of the conven ience functions may not oper­
ate, such as the interior lights or the power seat
adjustment. The convenience functions will be
available aga in when you turn on the ignition and
start the engine.
Winter operation
During the winter months, battery capacity tends
to decrease as temperatures drop. This is because
more power is also consumed while s tart ing, and
the headlights, rear window defogger, etc ., are
used more often .
Avoid unnecessary power consumption, part icu­
larly in city traffic or when traveling only short
d istances . Let your authorized Aud i dealer check
the capacity of the vehicle battery before w inter
sets in ¢
page 206 . A well charged battery will
not only prevent starting problems when the
weather is cold, but will also last longer.
(D Tips
If your vehicle is left standing for severa l
weeks at extremely low temperatures, the ve­
hicle battery should be removed and stored
where it will not freeze. This will prevent it
from being damaged and having to be re­ placed.
Checking and Filling

Replacing bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for
you .
It is becoming increasingly more and more diffi­
cult to replace vehicle light bulbs since in many
cases , other parts of the car must first be re­
moved before you are ab le to get to the bulb .
This applies especially to the light bulbs in the
front of you r ca r which you can only reach
through the engine compartment .
Sheet metal and bulb holders can have sharp
edges that can cause ser ious cuts, parts must be
Fuses and bulbs
correct ly taken apart and then properly put back
together to help prevent breakage of parts and
long term damage from water that can enter
housings that have not been properly resealed.
For your safety, we recommend that you have
your authorized Audi dea ler replace any bulbs for
you, since your dealer has the proper tools, the
correct bulbs and the expertise.
Gas discharge lamp s (Xenon lights)*:
Due to the high electr ical voltage, have the bulbs
replaced by a qualified technician . Head lights
with Xenon light are identified by the high volt­
age sticker.
A WARNING
Changing Xenon lamps without the necessary
equipment can cause serious personal injury.
- Bulbs are pressurized and can explode when
being changed . Potential risk of injury!
- On vehicles equipped with gas discharge
bu lbs (Xenon light) * life -threatening injuries
can result from improper handling of the
high -vo ltage portions of such lamps!
-On ly your authorized Audi dealer or quali­
fied workshop shou ld change the bulbs in
gas discharge lamps. There are parts with
sharp edges on the openings and on the
bulb holders that can cause serious cuts . If
you are uncertain about what to do, have
the wor k performed by an autho rized Audi
dealer or qualified workshop. Serious per­
sonal injury may result from improperly per­
formed work .
(D Tips
-If you st ill prefer to replace the light bulbs
yourself, be aware that the eng ine compart­
ment is a hazardous area to work
inq page 195 q &..
-It is best to ask your authorized Audi dealer
whenever you want to change a bulb.
