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, econo­
my and performance.
Trailer towing not only places more stress on the
vehicle, it also calls for more concentration from
the driver.
F or this reason, always follow the operating and
driving instructions provided and use common
sense.
Technical requirements
Tr aile r hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suitable
for your veh icle and trailer and must be mounted
securely on the vehicle's chassis at a technically
sound
location . Use only a trailer hitch with a re­
movable ball mount . Always check w ith the t rail­
er hitch man ufact urer to make su re that you are
using the co rrect hitch .
Do not use a bump er hit ch .
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 brake systems .
From t ime to t ime, check that a ll hitch mount ing
bolts rema in securely fastened.
When you are not tow ing a tra iler, remove the
tra iler hitch ba ll mount . This prevents the hitch
from caus ing damage shou ld your veh icle be
s truck from be hind ¢
,&..
Trailer brakes
If your trailer is equipped with a brak ing system,
check to be sure that it conforms to all regula­
tions .
190
The trailer hydraulic brake system must not be
directly connected to the vehicle's hydraulic
brake system ¢&. .
Safety chains
Always use safety chains between you r vehicle
and the trailer.
Trailer lights
Traile r lights must meet all regulations . Be sure
to check w ith your author ized Audi dealer for cor­
r ec t wiring , switches, and relays.
M irrors
If you are unable to see the traffic behind you us­
ing the regular outs ide mirrors, then you
must in­
stall extended mirrors . It is important that you
always have clear vision to the rear.
.&_ WARNING
- If a tra ile r has e lectr ica l brakes p lease no te
t hat these brakes are not activated by the
factory-fit ted contro l unit -risk of accident!
'
- After removing the trai ler hitch, do not
store it in your vehicle. In case of sudden
braking, the hitch co uld fly forward and in ­
jure you or yo ur passengers.
Operating instructions
Ma ximum traile r we ight
A trailer for your vehicle is limited to a typical
class 1 or class 2 trailer.
Trailer load distribution
Be sure the load in the trai ler is held securely in
place to p revent i t from shifting forward, back ­
ward or sideways.
Nev er allow a pa ssen ger to rid e in a trailer ¢ &.
in Driving instructions on page 191.
Engine cooling system
Towing a tra iler makes the engine work harder . It
i s important that the cooling system's perform ­
ance is up to the additional load. Make sure that
the cool ing system has enoug h fluid.

Tire pressure
When tow ing a tra ile r, infl ate the tires of yo ur
ve hicl e to the co ld tire press ure listed under "Fu ll
l oad" on the label located on the driver's side B­
pi llar (visib le when th e door is open). Inflate
tra ile r tir es to t railer and tire manufacture rs'
specifications.
Light s
The headlight settings should be checked wi th
the trai ler attached before driv ing
off . Check to
make sure both veh icle and trai ler lights are
wo rking prope rly .
Safety chains
Be s ure trai ler s afety chains are p ro p erly conne ct­
ed from the trailer to the hitc h on the vehicle .
L eave enough slack in the chains to permit turn­
ing corners . When you install safety cha ins, make
sure they w ill not drag on the road when yo u are
driving.
The chains s hou ld cross under the t railer tongue
to p revent it from dropp ing in case of separat ion
from t he hitc h.
Driving instructions
Driving with a trailer always requires extra core
and consideration.
To ob tain the best possible handling of vehicle
and trailer, please note the fo llowing :
.,. Do no t tow a lo ad ed t railer w hen yo ur car i tse lf
i s not lo ad ed.
.,. Be especia lly caref ul when passing ot he r
vehicles .
.,. Observe speed limits.
.,. Do not d rive at the maximum permissible
speed .
.,. Always apply brakes early .
.,. Moni to r th e temperature gauge .
Weight distribution
T owing a loaded trailer w ith an empty car res ults
in a high ly unstable distribution of weight . If this
cannot be avo ided, drive at very low speeds o nly
to avoid the risk of losing steering control.
Trailer mode
A "ba lanced" rig is easier to opera te and co ntrol.
This means that the tow vehicle sho uld be loaded
to the extent possib le and permissib le, w hile
keeping the trailer as light as possible under the
cir cumstances . Wheneve r poss ib le, transfer
some cargo to the luggage compartment of the
tow ve hicle while observing tongue load require­
ments and vehicle loa ding consi de rations .
Speed
The higher the speed, the mo re diff icult it be­
comes for the driver to control the r ig. Do not
drive at t he max imum permissib le speed. Reduce
you r sp eed even more if load, weathe r or wind
cond it ions are u nfavo rab le -pa rticularly when
go ing down hill.
Reduce vehicle speed
immediately if the trailer
shows the slightes t sign of sway ing .
Do not try
to stop the swaying by accelerating .
Observe speed limits . In some a reas, speeds fo r
vehicles towing trailers are lower tha n for regular
vehicles .
Always apply bra kes early . When d riving down­
hill, shift into a lower gear to use the e ngine
braki ng effect to slow the vehicle . Use of the
brakes alone can cause them to overhea t and fa il.
Coolant temperature
The coo lant tempe rature gauge c:> page 10 m ust
be obse rved caref ully. If the needle moves close
to the upper end of the scale, reduce speed im­
me diate ly and/or t urn
off th e a ir cond it io ne r .
If the coolant temperat ure warning light . in
t h e instr ument cluster starts flashing, pull
off
the road, stop and let the engine idle for about
two m inu tes to pre vent heat build -u p .

Checking and Filling
-To reduce the risk of being burned, never
open the hood if you see or hear steam or
coolant escaping from the engine compart­
ment . Wait until no steam or coolant can be
seen or heard before carefully opening the hood.
- Keep children away from the engine com­ partment.
- Never spill fluids on hot engine compo­
nents. They can cause a fire.
- Never touch the radiator fan. The auxiliary
electric fan is temperature controlled and
can switch on suddenly .
- Never open the coolant reservoir cap when
the engine is still warm. The coolant system is pressurized and hot coolant could spray
out.
- Protect your face, hands and arm from
steam or hot engine coolant by placing a
thick rag over the cap when you open the coolant reservoir.
- Do not remove the engine cover under any
circumstances. This increases the risk of
burns.
- If work on the fuel system or the electrical
system is necessary:
- Always disconnect the battery.
- Never smoke or work near heaters or open
flames. Fluids in the engine compartment could start a fire.
- Keep an approved fire extinguisher imme­
diately available.
- To avoid electrical shock and personal injury
while the engine is running or being started,
never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system .
- If you must perform a check or repair with
the engine running:
- First, fully apply the parking brake, move
selector lever of automatic transmission
204
to "P" (Park); put manual transmission in
Neutral.
- Always use extreme caution to prevent
clothing, jewelry, or long hair from get­
ting caught in the radiator fan, V-belts or
other moving parts, or from contacting hot parts . Tie back hair before starting,
and do not wear clothing that will hang or
droop into the engine.

Check ing and F illing
Using the proper engine oil is impo rtant for the
functionality and service life of the engine. Your engine was facto ry-filled with a h igh-quality oi l
which can usually be used throughout the entire
year.
@) Note
Your Limited New Vehicle War ranty does not
cover damage or malfunctions due to failure
to follow recommended maintenance and use
requirements as set forth in the Audi Owner's
Manual and Warran ty
& Maintenance booklet.
- Use only a high quality eng ine oil t hat ex-
p ressly complies with the Audi oil qua lity
standard specified for your vehicle's engine .
Using a ny o ther oil can cause serious engine
d am age.
- D o not mix any lubricants o r other addit ives
i nto the engine oil. Doing so ca n cause en­
g ine damage.

Engine oil consumption
The engine in your vehicle depends on an ade­
quate amoun t of oil to lubricate and cool all of
its moving parts .
In order to provide effective lubr ication and coo l­
ing of in ternal engine components, all internal
combustion eng ines consume a certain amou nt
of oil. Oil co nsumption varies from engine to en­
g ine and may change significant ly over the life of
206
th e engine. Typically, engines w ith a specified
break-in period (see
r=:> poge 185) consume more
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 oil con ­
sumption depends on the q ua lity and viscosity of
the oil, the RPM (revo lutions per m inute) at
which the engine is operated, the ambient tem­ perature and road condit ions. Further factors are
the amo unt of o il di lution from water condensa ­
t ion or fuel residue a nd the oxidation level of the
o il. As any engine is subject to wea r as mileage
builds up, the o il cons umption may increase ove r
t i me unt il repla ce m ent of wo rn components m ay
be come necessary .
With a ll these va riab les coming into p lay, no
sta ndard rate of o il cons umption can be estab­
li sh ed or spec ified . T he re is no alte rn ative to reg­
ul ar and frequen t checking of the oi l level, see
Note .
If the yellow engine oi l leve l wa rning symbo l Ill
in the instrument clus ter lights up , you sho uld
c h eck t he o il level as soon as possible

(D Tips
- The oil pressure 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 .

Check ing and F illing
@ For the sake of the environment
- Under no circumstances can the oil come in
contact with the sewage network or the soil.
- Observe and fo llow legal regulations when
disposing of empty oil containers .
Changing the engine oil
We recommend that hove your oil changed by on
authorized Audi dealer or a qualified service sta­
tion .
Before you che ck anything in the eng ine compart ­
ment,
always read and heed all WARNINGS ¢ A
in Working in the engine comportment on
page 203.
The engine oil must be changed according to the i n tervals specified in your Warranty
& Mainte­
nance booklet . This is very important because the
lubricat ing propert ies of oil diminish gradually
during normal vehicle use.
Under some circ umstances the eng ine oi l sho uld
be changed more frequently. Change oil more of­
ten if yo u drive most ly short distances, operate
the vehicle in dusty areas or under predominantly
stop-and-go traffic cond it ions , or have your vehi­
cle where temperatures remain below freezing
for extended periods .
Detergent additives in the oil will make fresh oil
look dark after t he engine has been run ning for a
short t ime . T his is normal and is not a reason to
cha nge the oil mo re often than recommended .
Because of the prob lem of proper disposal, along
with the special tools and necessary expertise re­
qu ired, we strongly recommend that you have
your oil c hanged by an aut ho rized
Audi dealer o r
a qualif ied se rvice station .
If you choose to change your o il yourself , please
note the following important informat ion:
A WARNING
To re duce the risk of pe rsonal injury if you
must c hange t he engine oil in your ve hicle
yo urs elf:
- W ear eye protection .
208
-
-To reduce the r is k of burns from hot engine
oil, let the engine cool down to the touch .
- W hen removing the oil drain plug with your
fingers, stay as far away as possible. Always
keep your forearm pa rallel to the ground to
he lp prevent hot oil from run ning down your
arm .
- Drain t he oil into a container designed for
this purpose, one large enough to hold at
leas t the tota l amou nt of oil in you r engine.
- Engi ne oil is poisonous . Keep it well out of
the reach of childre n.
- Continuous contact wit h used engine o il is
ha rmf ul to your skin. Always protect your

Cooling system
Coolant '
The engine coolant performs two functions: it
keeps the engine from overheating and it pro ­
tects the engine from free zing in the winter.
The coolin g system is sealed and generally re­
quires little attention .
The coo lin g sys tem h as been filled a t the fac to ry
wi th a pe rmanent coolan t which does not need to
be changed. The coo lant consists of a mixture of .,.

..... N
0 ::..:: co ..... ..... specially conditioned water and the man ufactur­
er's g lycol-bas edcoo lant additive Gl3 antifreeze
with anticorrosion additives (50% for USA mod­
e ls; 60% for Canadian models). This m ixture
both assures the necessary frost protection and
protects metal components in the engine's cool­
ing system from corrosion and scaling.
It also
raises the boiling point of the coolant .
Do not reduce the concentration of the coolant in
the summer by adding p lain water .
The propor­
tion of coolant addit ive must be at l eas t 50° /4
but not more th an 60 %
to maintain antifreeze
p rotection and cooling effic iency. If the coolant
frost protec tion is too low, the coolant co uld
freeze and damage the vehicle heating and en­
gine cooling system.
F or yea r-round driving, antifreeze is added at the
factory for temperatures down to :
- -31 °F (- 35 °C) USA
- -40 °F ( - 40 °C) Canada.
If you must add coolant, use a mixture of water
and coolant addit ive. Mixing the coolant additive
with d istilled water is recommended.
A WARNING
Before you check anything in the engine com­
partment, always read and heed all WARN ­
INGS
Q &. in Working in the engine compart­
ment on page 203.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in your
vehicle is sufficient to meet the climate con­
dit ions. This is especially important if you
li ve in a reg ion where the w inte r is ext reme­
l y co ld. If ne cessary, in cre ase the proport io n
of coo lant add itive to 60%.
- When addi ng coolant addit ive to you r cool­
i ng system, remember:
- We recommend using only coolant addi­
tive Gl2 ++ or Gl3 for your ve hicle. T his
coolant additive is available at authorized
Audi dea lers. Othe r types of antifreeze can
significant ly reduce cor ros ion p rotection .
Ch eck ing and Filling
The resulting co rrosion can cause a loss of
coolant and serious engine damage.
- Do not add any type of radiator lea k sealant
to your vehicle's engine coolant. Adding ra­
diator repair fluid may adversely affect the
function and performance of your cooling
system and cou ld resu lt in damage not cov­
ered by your New Veh icle Limited Warranty.
Checking the engine coolant level
The engine coolant level can be checked with a
quick glance.

With a cold engine, the coolant level
should be between the " MIN" and "MAX" mark­
ings. When the engine is warm, the level may
be slightly above the "MAX" marking.
The location of the coo lant expansion tank can be
seen in the engine compartment illustration
q page 205.
To obtain an accurate reading, the engine must
be switched off.
T he expansion ta nk in your veh icle is eq uipped
with an electric coo lant level senso r.

Check ing and F illing
blink until you add coolant and the level has been
restored to normal. Even though there is an e lec ­
tr ic coolant level sensor, we still recommend you
check the coo lant level from time to time.
Coolant los s
Coolant loss may indicate a l e ak in the cooling
system. In the event of coolant loss, the cooling
syst em should be insp ected immediately by your
authorized Audi dealer. It is not enough merely
to add coolant.
I n a
s e aled system, losses can occur only if the
boiling point of the coo lant is exceeded as a re­
sult of overheating.
A WARNING
The cooling system is under pressure and can get very hot. Reduce the risk of scalding from
hot coolant by following these steps.
- Turn off the eng ine and allow it to cool
