Trailer towing
Driving with a trailer
General information
Your Audi was designed primarily for passenger transpor
tation .
If you p lan to tow a t railer, p lease remember that the additional load
w ill affect durability, economy and performance.
Tr ailer towing not on ly p laces mo re s tress on the vehicle, it also calls
for more concentration from the driver.
For this reason, a lways follow the operating and dr iv ing inst ructions
prov ided and use common sense .

If you are going to tow a trailer, you must activate the tra iler ope ra
tion mode =>
page 168, "Towing a tra iler". •
Technical requirements
Trailer hitch
Use a we igh t-car rying h itch co nform ing to the gross tra iler we ig ht.
The h itch must be suitab le for your vehicle and trailer and must be
mou nted securely o n th e vehi cle's ch assi s at a
techni cally sound loc a
tion . Use only a trailer hitch with a removab le ball mount. Always
check wit h the t railer h itch manufactu rer to make sure that yo u are
using the correct h itch .
Do not use a bumper hitch.
The h itch mus t be installed in such a way t hat it does not in terfe re
w ith t he impact-absorb ing bumper system. No modifications shou ld be made to t
he veh icle exha ust and bra ke systems. From t ime to
time, check that a ll hitch mounting bo lts rema in securely fastened.
W hen you are no t tow in g a tra ile r, remove the t railer hit ch ball
mount. This prevents the hitc h from caus ing damage should your
vehicle be str uck from behind=>& .
Trailer brakes
If your trail er is e quipped w ith a b raking system, che ck to be s ure t hat
it conforms to all regulations.
T he tra ile r hydrau lic brake system m ust not be directly connected to
t he vehicle's hyd raulic b rake sys tem .
Safety chains
Always use safety chains between your veh icle and t he tra ile r.
Trailer lights
Trailer lights must meet all regulations. Be sure to check w ith your
Audi de aler fo r corr ec t wir ing , sw itches and re lays.
Mirrors
If you are unab le to see t he t raff ic be hind you using t he regular
outs ide mirrors, then you
must install extended mi rrors. It is impor
t an t th at yo u
always ha ve clear vi sion to the re ar.
& WARNING
After removing the trailer hitch, do not store it in your vehicle. In
case of sudden braking , the hitch could fly forward and inju re you
or your passengers. •
Operating instructions
Max imum tr aile r weight
A trai ler for your vehicle is lim ited to a typical class 1 or class 2 trailer.
Trail er lo ad di stribut ion
Be sure the load in the t ra iler is held secu rely in place to prevent it
from shift ing forward, backward or sideways.
N ev er a llow a pa ssenge r to ride in a traile r=>
& in "Driving instr uc
tions".
Eng ine c ooling s ystem
Towing a trailer makes the eng ine work harder. It is important that
the cooling system 's performance is up to the addi tional load. Make
sure that the cooling system has enough fluid.
Tire pre ssur e
When towing a tra iler, inflate the tires of your veh icle to the co ld tire
pressu re listed under "Full load" on the label located on the d river's
side 8 -pillar (visible when the door is open) . Inflate traile r tires to
t rai ler and tire manufacture rs' specificat io n s.
Light s
The headl ight sett ings shou ld be checked with the tr ailer attached
before driving off. Check to make sure both vehicle and trailer lights
are working properly .
Safety chain s
Be sure traile r safety cha ins are p roperly connected from the trai ler
to the hitch on the vehicle. Leave enough slack in the chains to perm it
tu rning corners. When you install sa fe ty cha ins, make s ure they will
not drag on the road when you are driving.
T he chains should cross under the trai ler tongue to prevent it from
dropping in case of separation from the h itch .

Driving instructions
Driving with a trailer always requires e xtra care and
consideration .
To obtain the best possible handling of vehic le and trailer,
please note the following:
- Do not tow a loaded trailer when your car itself is not
loaded.
- Be especially careful when passing other veh icles .
- Observe speed limits .
- Do not dr ive at the maximum permissible speed.
- Always apply brakes early .
- Monitor the temperature gauge .
Weight distribut ion
T owing a loaded tra iler w ith an empty car results in a highly unstable
distribution of we ight . If this cannot be avoided, d rive at very low
speeds only to avoid the risk of losing steering control.
A "balanced" r ig is easier to operate and control. This means that the
t ow ve hicle sho uld be loaded to the exte nt poss ible and permissib le,
wh ile keeping the tra iler as light as poss ible under the circumstances.
Whenever poss ible, tra nsfer some cargo to the l uggage compart
ment of the tow vehicle while observing tongue load requirements
and vehicle load ing considerations .

0 Note
• Never try to remove dirt, mud or dust if the surface of the vehicle
is dry. Never use a dry cloth or sponge, since this could scratch your
vehicle's paint or windows.
• Never wash your car in bright sunlight . Drops of water act as
magnifying lenses and may damage your pa int.
• When you wash your car in the winter: if you rinse your vehicle with
a hose, be careful not to a im the stream of water d irectly at locks, or
at door or hatch openings -they can freeze shut.
• Never use sponges designed to remove insects, or any kitchen
scouring sponges or similar products. They can damage your paint
fin ish .
• Never use a dry cloth or sponge to clean the headlights . Only use
wet cloths or sponges to prevent scratches . It is best to use soapy
water.
For the sake of the environment
In the interest of the environment, the vehicle should on ly be washed
in special wash bays. •
Washing your vehicle with a power washer
Cleaning the exterior of your car with a high-pressure
power washer is safe as long as you observe a few simple
rules .
-Before using the power washer, make sure you have read
and unders tood the WARNINGS ~
& in "General infor
mation" on
page 258.
- Always follow the operating instructions for the power
washer. -
Make sure that the jet on the spray hose produces a "fan
shaped spray".
- Do
not hold the spray nozzle too close to soft materials.
When cleaning the vehicle with a power washer always follow the
operating instructions. This applies particularly to the
operating
pressure
and the spraying distance. Maintain a sufficient distance to
soft materials such as rubber hoses and sound/vibration deadening
materials (particularly on the underside of the engine hood). Do not
use a jet which sprays water in a
direct stream or one that has a
rotating jet.
Water temperature should not exceed 140
°F (60 °() .
& WARNING
Never wash tires with a jet that sprays water in a direct stream.
This could cause invisible damage to the tires and weaken them,
even if the spray is from a relatively long distance and for a short
time. Damaged and weakened tires can fail and cause accidents
and personal injury .
0 Note
To avoid damaging your vehicle, always make sure that there is suffi
cient distance between the spray head and soft materials like rubber
hoses , plastic parts and sound-deadening mater ials. Never aim the
spray head at the same point for a long time. This a lso applies to
cleaning headlights and painted bumpers. Remember: the closer the
nozzle is to the surface of the material, the greater the stress on the
material. •

Changing the engine oil
The engine oil and oil fi lter must be changed according to the mileage
(kilometers) and t ime intervals specified in your vehicle 's Warranty
&
Maintenance booklet . Do not exceed these interva ls -harmful
deposits from o ld engine oil can reduce engine performance and can
lead to expensive engine repairs .
Changing the oil at the recommended intervals is so very impo rtant
because the lubricating properties of o il decrease gradually during
normal vehicle use. If you are not sure when you have your oil
changed, ask your author ized Audi Service Adv isor .
Under some circumstances the engine oil should even be changed
mo re frequently. Change oil more often if you drive mostly short
distances, operate the vehicle in dusty areas or mostly under stop
and-go traffic conditions, or when you use your vehicle where temper
atures stay be low freezing point for long periods.
Detergent addit ives in the oi l wi ll make fresh oil look dark after the
engine has been running for a short t ime. 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 intervals
using only engine oi l that complies with Audi oil standard
VW 502 00. Your Limited New Vehicle War ranty does not cover
damage or malfunctions due to fai lure to follow recommended main
tenance and use requirements as set forth in the Audi Owner 's
Manual and Warranty
& Maintenance booklet. Your dealer will have
to deny warranty coverage unless you present to the dealer proof in
the form of Serv ice or Repair Orders that all scheduled maintenance
was performed in a time ly manner. •
Engine oil consumption
The engine in your vehicle depends on an adequate
amount of oil to lubricate and cool all of its moving parts.
In order to provide effective lubrication and cooling of internal
eng ine components, all inte rnal combustion engines consume a
certain amount of oil. Oil consumption varies from engine to engine
and may change sign ifican tly over the lif e of the engine. Typically,
engines with a specified break- in period (see~
page 249) consume
more oil during the break-in period than they consume after oil
consumption has stab ilized .
Under normal conditions, the rate of oil consumption depends on the
quality and viscosity of the oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient temperature and road
conditions. Further factors are the amount of oil dilution from water
condensation or fuel residue and the ox idation level of the oil. As any
eng ine is subject to wear as mileage builds up, the oil consumption
may increase over time until replacement of worn components may
become necessary.
With all these variab les coming into play, no standard rate of oil
consumption can be established or specified . There is no alternative
to regular and frequent checking of the oil level , see
Note .
If the yellow engine oil leve l warning symbol in the instrument
cl uster lights up, you should chec k the oil level as soon as possible
with the oil dipstick~ page 281. Top off the oil at your earliest
convenience ~
page 282.
& WARNING
Before you check anything in the engine compartment, always
read and heed all WARNINGS~
& in "Working in the engine
compartment" on
page 277.

Brake fluid will damage the paint of your vehicle.
Because of the problem of proper disposal of brake fluid as well as
the special tools required and the necessary expertise, we recom
mend that you have the brake fluid changed by your authorized Audi
dealer. •
Battery
General information
Under normal operating condit ions, the battery in your Aud i does not
need any maintenance. With
high outside temperatures or long daily
drives we recommend that you have the electrolyte level checked by
a service facility. The electrolyte level should also be checked each
time the battery is charged~
page 290.
Have the battery checked when you take your vehicle in for service.
You are well advised to replace a battery that is older than 5 years.
With certain types of a irbag deployment, the battery is disconnected
from the vehicle electrical system for safety reasons=>
& in "Repair,
care and disposal of the airbags" on
page 209.
Disconnecting the battery terminals
Some vehicle functions (power window regulators, for example) are
lost if the battery terminals are disconnected. These functions have
to be relearned after the battery terminals are connected aga in. To
prevent this, the battery should only be disconnected from the
vehicle electrical system when absolutely necessary for repairs.
Vehicles not driven for long periods
If you do not drive your veh icle over a period of severa l days or weeks,
electrical components are gradually cut back or switched off. This
reduces energy consumption and maintains starting capability over a
longer period~
page 247.
Take into consideration that when you unlock your vehicle, some
convenience functions, such as the master key remote function or
power seat adjustment, may not be available. The convenience func
tions will be available again when you turn on the ign ition 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 starting, and the headlights, rear window defogger, etc., are used more often .
Avoid unnecessary power consumpt ion, particu larly in city traffic or
when traveling only short distances. Let your authorized Audi dealer
check the capacity of the vehicle battery before w inter sets in
=> page 290. A well charged battery will not only prevent starting
problems when the weather is cold, but will also last longe r.
(I] Tips
If your veh icle is left standing for several weeks at extreme ly low
temperatures, the vehicle battery should be removed and stored
where it will not freeze. This will prevent it from being damaged and
having to be replaced.•
