212 Trailertowing
Trailer towing Driving with a trailer
General information
Your Audi was designed primarily for passen
ger transportation .
If you plan to tow a trai ler, please remember
that the additional load will affect durability,
economy and performance .
Trailer towing not only places more stress on the vehicle, it also calls for more concentra
tion from the driver.
For this reason, always follow the operating
and driving instructions provided and use
common sense.
(D Note
If you are going to tow a trai ler, you must
activate the trailer operation mode
i::> page 212, Operating instructions .
Technical requirements
Trailer hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suita ble for your vehicle and trailer and must be
mounted securely on the veh icle 's chassis at a
technically sound location . Use only a trailer
hitch with a removable ball mount. A lways
check with the trai le r hitch manufacturer to
make sure that you are using the cor rect
hitch.
Do not use a bumper hitch.
The hitch must be installed in such a way that
it does not interfere with the impact-absorb
ing bumper system. No modifications should
be made to the vehicle exhaust and brake sys
tems. From time to time, check that all hitch
mounting bo lts remain securely fastened.
When you are not towing a trailer, remove the
trailer hitch ball mount. This prevents the
h itch from causing damage should your veh i
cle be struck from behind~ &.
Trailer brakes
If your trailer is equipped with a brak ing sys
tem, check to be sure that it conforms to all
regulations.
T he trailer hydraulic brake system must not be
direc tly connected to the vehicle's hydraulic
brake system .
Safety chains
Always use safety chains between your veh icle
and the tra iler.
Trailer lights
Trailer lights must meet all regulations. Be
sure to check with your Audi dealer for correct
wiring, switches and relays.
Mirrors
If you are unable to see the traffic behind you
using the regular outside mirrors, then you
must install extended mirrors. It is important
that you
always have clear v is ion to the rear .
A WARNING ,~ -
After removing the trailer hitch, do not
store it in your vehicl e. In case of sudden
braking, the hitch could fly forward and in
jure you or your passengers.

drive at the maximum permissible speed. Re
duce your speed even more if load, weather or
wind condit ions are unfavorable -part icu larly
when going downhill.
Reduce vehicle speed
immedi atel y if the trail
er shows the slightest sign of swaying .
Do not
tr y to stop th e sway ing by acceler ating .
Observe speed limi ts. In some areas, speeds
for vehicles towing trailers are lower than for
regular vehicles .
A lways apply brakes early. When driv ing
downhill, shift into a lower gear to use the en
gine braking effect to slow the vehicle . Use of
the brakes a lone can cause them to overheat
and fail.
Coolant t emperature
The coolant temperature gauge ¢ page 10
must be observed carefully. The coolant tem
perat ure can increase if you drive on long in
clines in a low gear at high engine speeds. Re
duce your speed immediate ly if the L EDs in
the top part of the display turn on.

A WARNING
Anyone not properly restrained in a mov
ing veh icle is at a much greater risk in an
accident . Never let anyone ride in your car
who is not properly wear ing t he restra ints
provided by Aud i.
Trailer towing tips
Important to know
Your vehicle hand les different ly when towing
-
a trailer because of the addit ional weight and
d ifferent weight distribution . Safety, perform
ance and economy w ill greatly depend on how
carefully you load your trailer and operate
your rig.
Before you actually tow your trailer, practice
turning, stopp ing and back ing up in an area
away from traffic . Keep practicing until you have become completely familiar with the way
your vehicle-trailer combination behaves and responds .
Backing up is diffi cult and requ ires practice .
Backing up with a trailer gene rally req uires
steering action opposite to that when backing
up your vehicle without a tra iler.
Maintain a greater d ista nce between you r ve
hicle and the one in front of you . You wi ll need
more room to stop. To compensate for the
trailer, you w ill need a larger than normal
turning rad ius.
When passing, remember that you cannot ac
ce lerate as fast as you norma lly would be
ca use of the added load. Make sure yo u have
enough room to pass. After passing, allow
plenty of room for your trailer be fore chang
ing lanes again .
Avoid jerky starts, sharp turns or rapid lane changes.
(D Tips
- Do not tow a trailer during the break-in
period of your vehicle .
- If you tow a trailer, your Audi may re
quire more frequent maintenance due to
the extra load ¢
page 292.
Parking on a slope
Do not park on a slope with a trailer. If it can
not b e avoided, do so only after doing th e fol
lowing:
When par king:
.,. App ly the foot brake.
.,. Have someone p lace chocks under both the
vehicle and the tra iler wheels .
.,. With chocks in place, slowly release the
brakes unt il the wheel chocks absorb the
load .
.,. Turn the whee ls towards the curb .
.,. Apply the parking brake .
.,. Select the P se lector lever posit ion.
When re starting after parking:
.,. App ly the foot brake.
Vehicl e ca re a nd cl eanin g 217
Rinse the vehicle thoroughly again and let it
air dry. Remove any water residue using a
shammy .
Stubborn depos its s uch as bird dropp ings or
tree sap are best removed with plenty of wa
ter and a microfiber cloth.
A WARNING
-Only wash the vehicle when the ignition
is off and follow the instructions from
the car wash operator to reduce the risk
of accidents .
- To reduce the risk of cuts, protect your
self from sharp metal components when
wash ing the underbody or the inside of
the wheel housings .
- After washing the vehicle, the braking ef
fect may be delayed due to mo isture on
the brake rotors or ice in the winter. The
brakes must be dried first with a few
careful brake applicat ions .
- If you wash the vehicle in an automatic
car wash, you must fold the exterior m ir
rors in to reduce the r is k of damage to
the mirrors. Power folding exterior m ir- rors* must only be fo
lded in and out us
ing the power folding fu nction .
- T o prevent paint damage, do not wash
the vehicle in direct sunlight.
- T o reduce the r is k of damage to the sur
face, do not use insect removing spong
es, kitchen sponges or similar items.
- Matte finish painted vehicle compo
nents:
- To reduce the risk of damage to the
surface, do not use polishing agents or hard wax.
- Never use car wash cycles that apply
protective wax. It can destroy the
matte fin ish effect .
- Do not place any stickers or magnet ic
signs on vehicle parts painted w ith
matte fin ish paint. The paint cou ld be
damaged when the stickers o r magnets
a re removed.
@ For the sake of the environment
Only wash the vehicle in facilities spec ially
designed for that p urpose . This will reduce
the r is k of dirty wate r contam inated with
oil from entering the sewer system.

Engine oil
Engine oil specifications
The engine oil used in your Audi needs the
right kind of oil.
-
The engine in your Audi is a sophisticated
powerp lant that was built to exacting specifi
cations . This engine needs the r ight kind of
engine o il that meets spec ificat ions regarding
qua lity and viscos ity so that it can run
smoothly and reliably . Choos ing the righ t oi l
and changing oil within the time and mileage interva ls printed in your vehicle 's Warranty
&
Maintenance book let matters a lot more to
day than it did years ago. Audi has developed
a special quality standard for engine oil that
will help assure that your veh icle's eng ine will
get the lubrication it needs for proper opera
tion.
Modern engine lubrication has taken a quan
tum leap in the last few years. Many synthetic
oils ava ilable today provide better engine lu
brication that can outlast trad itional petrole -u
m -based oils, making them a smart choice
for use throughout the life of your Audi.
Whether you use synthet ic o r petro le um
based eng ine oil, the oi l that you use m ust
conform to Audi's oi l quality standard
VW 502 00 (vehicles with gasoline engine) or
VW 507 00 (vehicles with d iese l eng ine) to
help keep your veh icle's engine running
smoothly and help prevent the format ion of
harmful deposits, sometimes called "s ludge,"
that over time can lead to expens ive repairs.
At the time of printing, engine oils ava ilab le in
the U.S. and Canada that meet the exacting
specifications of Audi oil standard VW 502 00 (ve hicles w ith gasoline eng ine) o r VW 507 00
(veh icles w ith diese l eng ine) are synthet ic en
gine o ils . This does no t mean, howeve r, that
every synt hetic eng ine oil will meet A udi oi l
standard VW 502 00 (veh icles with gasoline
engine) or VW 507 00 (vehicles with diesel
engine). So a lways be sure that you use an ap
proved o il.
T o he lp preven t the formation of harmfu l de
posits use on ly oil with the following specifi
cations printed on the o il container:
- Audi oil standard VW 502 00 (g aso line en
gine )
- Audi oil standard VW 507 00 (die sel en-
gine )
Oil container labels may car ry the spec ifica
t ion sing ly or in combination with othe r desig
na tions and oil quality standa rds.
Viscosit y
Engine oi ls are graded according to their vis
cosity . The proper viscos ity grade oil for your
engine depends on climactic or seasona l con
ditions where you drive . You can use o il with a
viscosity grade of SA E 5W40 across all tem
perature ranges for normal dr iv ing cond itions .
However, if engine oil viscosity grade SAE
5W40 is not ava ilable, you can also use v iscos
i ty grade SAE 5W-30 or SAE OW-40 as long as
it meets Audi oil quality standard VW 502 00
(ve hicl es w ith gasoline eng ine) o r VW 50 7 00
(ve hicles w ith diese l engine) specifica tions. .,.
236 Check ing and filling
Engine oil consumption
Th e e ngine in your vehicle depends on an ad e
quate amount of oil to lubricate and cool all
of its moving parts.
In o rder to prov ide effec tive l ubrication and
c o oling of i nternal engi ne components, all in
t e rnal com bustion eng ines consume a certa in
a m ount of o il. O il consumption var ies from
engine to eng ine and may change significant ly
ove r the life o f the eng ine . T ypica lly, eng ines
with a specified break -in per iod (see
<=>
page 207) cons ume more oil during the
break -in period than they consume after oil
consumption has stabilized.
Under normal conditions, the rate of oil con
sumption depends on the quality and viscosity
of the oi l, the RPM (revo lutions per minute) at
which the engine is operated, the ambient
temperature and road condit ions. Further fac
tors are the amount of oil d ilution from water
condensation or fuel residue and the ox ida
tion level of the oil. As any engine is subject to
wear as mileage bu ilds up, the oil consump
tion may in crease over t ime un til replacement
of worn componen ts may become necessa ry.
W ith all these var iables coming into play, no
standa rd rate of o il consumption can be es
tablished or specified. The re is no alterna tive
to regular and frequen t checking of the oi l lev
e l, see
Note .
If the ye llow eng ine o il level warn ing symbol
in the in strumen t cluste r

your engine at regular intervals, pref
erably each time you refuel , and always
before going on a long trip .
-If you have the impression your engine
cons umes excessive amounts of oil, we
recommend that you consult your Aud i
dea ler to have the cause of your con cern
prope rly d iagnosed. Keep in m ind that
t he accurate meas urement o f oil c on

Checking the engine coolant level
The engine coolant level can be checked with
a quick glance .
Fig . 204 Eng ine compartment: cover on the coolant
expa nsion tank
Before you check anything in the engine com
partment,
a lwa ys re ad and h eed a ll WA RN
INGS o .A in Working in the engine compart
ment on page 231 .
Park your vehicle on a level surface.
• Switch
off the ignition .
• Read the engine coolant leve l from the cool
ant expansion tank
o fig. 204, o page 233.
With a cold engine, the coolant level should
be betwee n the "min" and "max" markings.
When the engine is warm, the level may be slightly above the "max" marking .
The location of the coolant expans ion tank
can be seen in the engine compartment illus
tration
o page 233.
To obtain an accurate reading, the engine
must be switched
off.
The expansion tank in your vehicle is equipped
with an e lectric coolant level sensor.
When the coolant level is too low, the warning
light in the Auto-Check System
o page 16 wi ll
illuminate unti l you add coolant and the level
has been restored to normal. Even though
there is an electric coolant level sensor, we
still recommend you check the coolant level
from time to time.
Coolant l oss
Coolant loss may indicate a le ak in the cooling
system. In the event of coolant loss, the cool- ing system shou
ld be inspected immediately
by your authorized Audi dea ler . It is not
enough mere ly to add coo lant .
In a
sea le d system, losses can occur on ly if
the boiling point of the coo lant is exceeded as
a res ult of overheating.
A WARNING
-The cooling system is under pressure and
can get very hot. Red uce the risk of scald
i ng from hot coolant by fo llow ing these
steps.
- Turn
off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escaping flu id and steam by covering the
cap with a large, th ick rag.
- Turn the cap slowly and very carefully in
a counter-clockwise d irect ion while ap
plying light, downward pressure on the
top of the cap.
- To avo id being burned, do not sp ill anti
freeze or coolant on the exhaust system
or hot engine parts. Under certa in cond i
tions, the ethylene glycol in engine cool
ant can catch fire.
0 Note
Do not add any type of radiator leak seal
ant to your veh icle's engine coolant . Add
i ng radiator repa ir fluid may adverse ly af
