198 Trailer towing
Trailer towing Driving with a trailer
General information
Your Audi was designed primarily for passen­
ger transportation .
If you plan to tow a tra iler, p lease remember
that the addit ional load will affect durability,
economy and performance .
T railer towing not on ly places more stress on
the vehicle, it also calls for more concentra­
tion from the driver.
F or this reason, always fo llow the operating
and drivi ng in str uctions provided and use
common sense.
@ Note
If you are going to tow a trai le r, you must
activate the trailer operation mode
c:::> page 198 , Operating instructions.
Technical requirements
Traile r hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suita­
b le for your veh icle and trailer and must be
mo unted secure ly on the ve hicle's chassis at a
technically sound loca tion . Use only a trailer
hi tch with a removab le ball moun t. A lways
check with the tra ile r hitch manufac turer to
make sure that you are using t he cor rect
hitch.
Do not use a bumper hit ch .
The hitch must be installed in such a way that
i t does not interfe re 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 th at a ll hitch
mo unt ing bo lts remain securely fastened.
When you are not towing a trailer, remove the
tra iler hitch ball moun t. T his prevents the
h itch from causing damage sho uld your veh i­
cle be str uck from be hind
c:::> A .
Trailer brake s
If your trailer is equipped wi th a b ra ki ng sys­
tem, c heck to be sure t hat i t conforms to all
regulations .
T he trailer hyd rauli c brake system mus t not be
direc tly connec ted to the vehicle's hydraulic
brake system .
Safety chains
Always use safety chains between your veh icle
and the tra ile r.
Trailer lights
Trai ler lights must meet all regulations. Be
sure to check w ith your Audi dealer for correct
wiring, switches and relays .
Mirrors
If you are unable to see the traffic behind you
us ing the regular o utside mirrors, then you
must install extended mirrors. It is important
that you
always have clear v is ion to the rear.
A WARNING
--
Afte r removi ng the trailer hitch, do not
stor e it in your vehicle . In case of sudden
b raking, t he hitch co uld fly forwa rd and i n­
j ur e you or your passengers.
Operating instructions
Maximum trailer weight
A tra ile r fo r your vehicle is limited to a typical
class 1 or class 2 tr ailer.
Trailer load distribution
Be sure the load in the tra ile r is held secure ly
i n place to p revent it from shift ing forward,
backward or sideways.
Ne ver allow a pa ssenger to ride in a trailer
c:::> A in Driving instructions on page 199 .
Engine cooling system
Towing a trailer makes the engine work hard­
er . It is important that the cooling system's
performance is up to the additional load.

Make sure that the cooling system has enough
f luid .
Tire pressure
When tow ing a trai ler, inflate the t ires of your
veh icle 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 trai ler and tire manufac­
turers' specifications.
Lights
Check to make sure both veh icle and trailer
lights are working properly.
Safety chains Be sure tra iler safety cha ins are properly con­
nected from the trailer to the hitch on the ve­
hicle. Leave enough slack in the chains to per­
mit turning corners . When you install safety
chains, make sure they wi ll not drag on the
road when you are driving.
The chains should cross under the trailer
tongue to prevent it from dropping in case of
sepa ration from the hitch.
Driving instructions
Driving with a trailer always requires extra
care and consideration.
To obta in the best poss ible handling of vehicle
and trai le r, p lease note the following:
.. Do not tow a loaded tra iler when your car it ­
self is not loaded .
.. Be especially carefu l 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
Tow ing a loaded trailer with an empty ca r re­
sults in a high ly unstable distribution of
weight . If this cannot be avoided, drive at very
Trailer towing 199
low speeds on ly to avoid the risk of losing
steering contro l.
A "balanced " rig is easier to operate and con­
trol. This means that the tow vehicle should
be loaded to the extent possible and permissi­
ble, while keeping the trailer as light as possi­
ble under the c ircumstances. Whenever poss i­
ble, transfer some cargo to the luggage com­
partment of the tow vehicle while observing
tongue load requirements and vehicle loading
considerations.
Speed
The higher the speed, the more difficu lt it be­
comes for the driver to control the rig. Do not
drive at the maximum permissible speed. Re­
duce your speed even more if load, weather or
wind conditions are unfavorable -particularly
when going downhill .
Reduce vehicle speed
immediately if the trail­
er 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 veh icles .
Always apply brakes early. When driving
downhill, shift into a lower gear to use the en­ gine braking effect to slow the vehicle . Use of
the brakes alone ca n cause them to overheat
and fail.
Coolant tempe rature
The coo lant temperature gauge¢
page 12
must be observed carefully. The coolant tem­
perature can increase if you drive on long in­
cli nes in a low gear at high engine speeds . Re ­
duce your speed immediately if the LEDs in
the top part of the display turn on.

A WARNING
Anyone not properly restrained in a mov­
ing vehicle is at a much greate r risk in an
accident. Never let anyone ride in yo ur car

care products with household trash.
Car washes
T he longer that deposits such as insects, bird
droppings, tree sap or road sa lt rema in on the
veh icle, the more the surface can be dam­
aged . High tempe ratures such as those
caused by sunlight increase the cor rosive ef­
fect .
Before washing, rinse off heavy depos its with
p lenty of water .
Also, was h the underside of your ve hicle once
road salt stops be ing used for the season.
P ressure wash ers
When washing your veh icles w ith a pressure
washer, always fo llow the operating instruc­
tions provided with the pressure washe r. T his

214 Checking and Filling
you have your oil changed, ask your author­
ized Audi Service Advisor.
Under some circumstances the engine oil
should even be changed more frequently .
Change oil more often if you drive mostly
short distances, operate the vehicle in dusty
areas or mostly under stop-and-go traffic con­
ditions, or when you use your vehicle where
temperatures stay below freezing point for
long periods .
Detergent additives in the o il wi ll make fresh
oil look dark after the engine has been run­
ning for a short time. This is normal and is not
a reason to change the oil more often than recommended .
Damage or malfunctions due to lack of
maintenance
It is essential that you change your oil at the
recommended interva ls using only engine oil
that complies with Audi oil standard
VW 502 00. Your Lim ited New Vehicle War­
ranty does not cover damage or malfunctions
due to fa ilure to follow recommended mainte­
nance and use requ irements as set forth in
the Audi Owner's Manual and Warranty
&
Maintenance booklet . Your dea ler will have to
deny warranty coverage un less yo u present to
the dea ler proof in the form of Service or Re­
pair Orders that all schedu led maintenance
was performed in a timely manner.
Engine oil consumption
The engine in your vehicle depends on on ade­
quate amount of oil to lubricate and cool all
of its moving ports.
In order to provide effective lubrication and
cooling of internal engine components , a ll in­
ternal combustion eng ines consume a certain
amount of o il. Oil consumption var ies from
engine to engine and may change significantly
over the life of the eng ine . Typically, engines
with a specif ied break-in period (see
¢
page 193) consume more oil during the
b reak-in period than they consume after oil
consumption has stabilized. Under
normal conditions, the rate o f oil con ­
s u mption depends on the quality and viscosity
of the oil, the RPM (revolut ions per minute) at
which the engine is operated, the ambient
temperature and road conditions. Further fac­
tors are the amount of oil dilut ion from water
co nd ensat ion or fuel residue and the oxida­
t ion level of the oil. As any engine is subject to
wea r as mileage builds up, the oil consump­
tion may increase over time until replacement
of worn components may become necessary.
With a ll these variab les coming into play, no
standard ra te of oil consumpt io n can be es­
tablished or specified. There is no alternative
to regu lar and frequent check ing of the oil lev­
el , see
Note.
If the yellow engine oil leve l warning symbo l
Ill in the instr ument cl uster light s up, you
shou ld check the oil leve l as soon as possible
¢
page 215. Top off the oil at your earliest
convenience
~ page 215.
A WARNING

Before you check anything in the engine
compartment, always read and heed all
WARNINGS¢
page 210.
(D Note
Driving wit h an insufficient oil level is like­
l y to cause severe damage to the engine.
(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 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
consumes excessive amounts of oil, we
recommend that you consult an author­
ized Aud i dea ler to have the cause of
your concern properly diagnosed. Keep in
mind that the accurate measurement of
oil consumption requ ires great care and
may take some time. An authorized Audi ..,.

The cooling system has been filled at the fac­
tory with a permanent coolant which does not need to be changed. The coolant consists of a
mixture of spec ia lly conditioned water and the
manufacturer's glycol-based coolant addi-
tive Gl3 antifreeze with anticorros ion addi ­
tives (50% fo r USA models; 60% for Canadian
models) . This mixture both assures th e neces­
sary frost protect ion a nd p rotects me tal com ­
ponents in the engine 's coo ling system from
corrosion and scaling.
It al so raises the boil­
ing po int o f the coo lant .
D o no t reduce the concentration of t he coo l­
an t in the summer by ad ding plain w ate r.
The
proportion of coolant additive must be at
lea st 50 % but not more than 60%
to main­
tain ant ifreeze protection and cooling efficien­
cy. If the coolant frost protect ion is too low ,
the coolant cou ld free ze and damage the veh i­
cle heating and eng ine cooling system.
F or yea r-round driv ing, antifreeze is added at
the facto ry for temperatures down to:
- -3 1 °F ( -3 5°C) USA
- -4 0°F ( -4 0°C) Canada.
If you must add coolant, use a m ixture of wa ­
ter and coolant addit ive. M ixing the coolant
addi tive wi th dist illed wate r is recom mend ed.

• Add coolant mixed in the correct ratio
¢page 216 up to the upper marking.
• Make sure that the fluid level rema ins sta-
ble. Add more coolant if necessary.
• Clove the cap securely.
A coo lant loss suggests a leak. Immediately
drive your vehicle to an authorized repair fa­
cility and have the coolant system inspected.
If the coolant system is not leaking, a loss can
come from the coolant cooking through over­
heat ing and being pushed out of the coolant
system.
.8, WARNING
The cool ing system is under pressure and
can get very hot. Reduce the risk of scald­
ing from hot coolant by following these
steps .
- Do not open the coo lant expansion tank
cap with the engine hot . There is a risk of
burns.
- T urn off the engine and allow it to cool
down .
- Protect your face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag.
- T urn the cap slowly and ve ry carefu lly in
a counter-clockwise direction wh ile ap­
plying light, downward pressure on the
top of the cap.
- To avoid being b urned, do not spill anti­
freeze or coo lant on the exhaust system
or hot eng ine parts. Under certain condi­
t ions, the ethylene g lycol in engine cool­
ant can catch fire.
- The coo lant add itive and the coolant can
be dange rous to your hea lth. For th is
reason, keep the coolant in the or ig inal
conta iner away from children. There is a
risk of poisoning.
- Whe n work ing in the engine compart­
ment, remembe r that the radiator fan
can swit ch on even if the ignition is
switched off, wh ic h increases the risk of
persona l inju ry .
(D Note
Do not add coo lant if the expansion tank is
empty. Air cou ld enter the cooling system
and damage the engine. If this is the case,
do not continue dr iving. See your author­
i zed Audi dealer or qualified repair fac ility .
Radiator fan
The radiator fan switches on automatically by
itself
An a uxiliary electric radiator fan switches on
and off depending on coolant temperature
and other vehicle operat ing condit ions.
After you switch the engine off, the auxi liary
fan can continue running for up to 10 m inutes
- even w ith the ignition off.
It can even switch
on again later by itself¢.&. , if
- the temperature of the engine coo lant rises
due to the heat build- up from the engine in
the engine compartment, or
- the engine compartment heats up because
the vehicle is parked in intense sunlight.
.8, WARNING ,-
- To reduce the risk of personal injury nev-
er touch the radiator fan.
- The a uxiliary electric fan is temperat ure
controlled and can sw itch on suddenly
even when the engine is not ru nning.
- The auxiliary radiator fan sw itches on a u­
tomatically when the engine coo lant
reaches a certain temperature and will
continue to run until the coolant temper­
ature drops.
