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 durab ility,
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, a lways fo llow the operating
and driving instructions provided and use
common sense.
Technical requirements
Traile r hitch
Use a weight-carrying hitch conforming to the
gross trailer we ight. The hitch must be suita
b le for your veh icle and trailer and must be
mounted secure ly on t he veh icle's chassis at a
technically sound location . Use only a t railer
h itch w ith a removab le ball moun t. A lways
check with the tr ailer hitch man ufac tur er to
make sure that you are using the correct
hitch.
Do not use a bumper hitch.
T he hitc h must be installed in such a way that
it does not inte rfe re with the impac t-absorb
i ng b umper syst em. No modifica tions should
be made to the vehicle exhaus t and b rake sys
tems . From t ime to time, check that a ll hitch
mo unt ing bolt s remain securely fas tened.
W hen you are not tow ing a trailer, remove the
trai le r hi tch ball moun t. T h is prevents the
hi tch from causing damage sho uld your ve hi
cle be str uck from be hind
¢ &. .
Trailer brakes
If yo ur tra iler is equ ipped w it h a braking sys
tem, check to be su re that it conforms to a ll
r eg ulat io ns.
Trailer towin g 201
The trailer hyd ra ulic bra ke system must not be
direct ly connected to the vehicle's hydraulic
brake system .
Safety chains
Alw ays use saf ety chains between your ve hicle
and t he tra ile r.
Trailer lights
Tra iler lights must meet all reg ulations . Be
su re to check with your Audi dea ler fo r cor re ct
wir ing, swi tches and relays.
Mirrors
If you a re unable to see the traffic behind you
u sing the regula r outside m irrors, then you
must i nsta ll ext ended mir rors . It is important
t h at you
always have clea r vis ion to the rear .
.8, WARNING
-
Afte r removing the trailer hit ch, do no t
s tore i t in yo ur vehicle . In case of sudden
b raking, the h itch cou ld fly forwar d an d in
ju re you or yo ur passengers .
Operating instructions
Maximum trailer weight
A tra ile r fo r you r vehicle is limited to a ty pical
cl ass 1 or class 2 tra ile r.
Trailer load distribution
B e sure the loa d in the tr aile r is held secure ly
i n place to p reven t it from shift ing forw ard,
ba ckward or sideways.
Never allow a passenger to ride in a trailer
¢ &. in Driving instru ctions on page 20 2.
Engine cooling system
Towing a trailer makes the engine work hard
er . It is impo rtant that the cooling system's
perfo rmance is up to the additional load .
Make sure that the coo ling syst em has enough
f lui d.
Tire pressure
When towing a trailer , inflate the tires of your
vehicle to t he cold tire pressure listed under .,..

202 Trailer towing
"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 t ire manufac
turers' specif ications.
Lights
Check to make sure both vehicle and trailer
lights are working properly.
Safety chains
Be sure trailer safety chains 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
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 trailer, please note the following:
.. Do not tow a loaded trailer when your car it
self is not loaded.
.,. Be especia lly careful when passing other
ve
hicles.
.. 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 re
sults in a high ly unstable distribution of
weight . If this cannot be avoided, drive at
very
low speeds only to avoid the risk of losing
steering control.
A "balanced" rig is easier to operate and con
trol. This means that the tow vehicle should
be loaded to the extent poss ible and permissi
ble, while keeping the trailer as light as possi
ble under the circumstances . Whenever possi- ble,
transfer some cargo to the luggage com
partment of the tow vehicle while observing
tong ue load requirements and vehicle loading
considerations.
Speed
T he higher the speed, the more difficult 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 trai lers are lower than for
regular vehicles .
Always apply brakes early. When driving
downhi ll, shift into a lower gear to use the en
gine braking effect to s low the vehicle. Use of
the brakes alone can cause them to overheat
and fail.
Coolant temperature
The coolant temperature gauge¢ page 11
must be observed carefu lly. The coolant tem
perature can increase if you drive on long in
clines in a low gear at high engine speeds. Re
duce your speed immediately if the LEDs in
the top part of the d isplay turn on .
For more information about indicator lights,
refer to. ¢
page 16 .
A WARNING
Anyone not properly restrained in a mov
ing vehicle is at a much greater risk in an
accident. Never let anyone ride in your car
who is not properly wearing the restraints
provided by Audi.
Trailer towing tips
Important to know
Your vehicle handles differently when towing
a trai ler because of the additional weight and ..,.

206 Cleaning and protec tio n
directly 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 finish.
- 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.
- You should remove debris (such as in
sects) from the headl ight lenses on a
regular basis, for example when refuel
i ng your vehicle. Never clean the head
li ghts w ith a dry cloth or sponge. Use a
wet cloth or sponge.
It is best to use
soapy wa ter.
@ For the sake of the environment
In the interest of the envi ronment, the ve
hicle sho uld only be washed i n special
was h 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.
.. Befo re using the power washer , make sure
yo u have read and understood the WARN
INGS¢
A in General information on
page 204.
.. Always fo llow the operating instructions for
the power washer .
.. Make sure that the jet o n the spray hose
produces a "fan shaped spray" .
.. Do
not hold the spray nozzle too close to
soft materia ls .
When cleaning the veh icle with a power wash
er
always follow the operating instructions .
This applies particularly to the
op erating
pr essure
a nd the s pray ing di stance . Keep a
d ista nce from soft materials such as rubber
hoses o r insulat ing ma ter ial as well as sensors
and camera lenses . Do not use a jet which sprays water in a
d
ir ect
stream
or one t hat has a rotating jet .
Water temper ature sho uld not ex ceed 140 °F
(60 °().
A WARNING ~ -
Neve r wash tires with a jet that sprays wa
ter i n a direct stream. This could cause in
vis ib le damage to the t ires and weaken
them, even if the spray is from a re lative ly
l ong distance and for a short time. Dam
aged and weakened tires can fail and cause
accidents and personal inj ury.
'
([) Note
To avoid damaging your vehicle, a lways
make sure that there is suffic ient d istance
between the spray head and soft materia ls
like rubber hoses, plast ic pa rts and sound
deaden ing mater ials as w ell as sensors
and camera lenses. Neve r aim t he sp ray
head at the same point for a long time.
This also applies to cleaning headligh ts
and painted bumpers. Remembe r: the
closer the nozzle is to the surface of the
materia l, the greater the stress on the ma
terial.
Sensors and camera lenses
- Remove snow with a hand br ush and remove
ice with a de- ic ing spray that does not con
tain so lvents .
- Clea n the sensors (adaptive cruise control*,
pa rk ing system*) w ith a cleaning so lution
that does not contain so lvents and a soft
cloth .
- The camera lens or the area in front of the
came ra le ns is no rmally cleaned by the
w indshie ld w ipers o r he adlig ht wipers (night
vision system *).
If the lens or the area is ex
ceptionally di rty, clean the area wit h glass
cleaner and a soft, dry cloth .
(D Note

temperatures stay below freezing point for
long periods.
Detergent add it ives in the o il w il l make fresh
oil look dark after the eng ine has been run
ning for a short time . This is norma l and is not
a reason to change the oi l more often than
recommended.
D am age or m alfunc tions du e to lack of
m ainten ance
It is essential that you change your oil at the recommended in tervals using only engine o il
that complies with Audi oi l standard
VW 502 00. You r Limited New Vehicle War
ranty does not cover damage or malfunctions
due to fail ure to fo llow recommended mainte
nance and use requ irements as set forth in
the Audi Owner's Manual and Warranty &
Maintenance book let . Your dealer will have to
deny warranty coverage unless you present to
the dea ler proof in the form of Service or Re
pa ir Orders that all scheduled ma intenance
was performed in a t imely manner.
Eng ine 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 ing of internal engine components, a ll in
ternal comb ustion eng ines consume a certa in
amount of oil. O il consumption varies from
engine to engine and may change significantly
over the life of the engine. Typica lly, engines
with a specif ied break-in period (see
¢
page 196) consume more oil during the
break-in period than they consume after oil
consumption has stabilized.
Under norma l conditions, the rate of oil con
sumpt ion depends on the quality and viscosity
of the oil, the RPM (revolutions per m inute) 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
condensat ion or fuel residue and the ox ida
tion level of the oi l. As any engine is subject to wear as mi
leage 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 rate of oil consumption can be es
tablished or specified. There is no alternative
to regu lar and frequent check ing of the o il lev
el, see Note.
If the yellow engine oil leve l warning symbo l
in the instrument cluster
II! lights up, you
shou ld check the oil leve l as soon as possib le
¢
page 225. Top off the oil at your earliest
convenience
¢ page 225.
A WARNING '"---
Before you check anythi ng in the engine
compartment, always read and heed all
WARNINGS¢
A in Working in the engine
compartment on page 220.
(D Note
Driving w ith an insufficient o il level is like
ly to cause severe damage to the engine .
(D Tips
-The oil pressu re warn ing display. is
not an indic ator of the oil le vel. Do not

before going on a long trip .
- If you have t he impression yo ur engine
cons umes ex cessive amoun ts of o il, we
recommend that you consu lt your Aud i
dea ler to have the cause of your concern
properly diagnosed. Keep in mind that
the accurate meas urement of oi l con
sumption requ ires great care and may
take some t ime. Your Audi dea ler has in
structions about how to measure oil con
sumption accurately.

Have the battery checked when you take your
vehicle in for service. Yo u are well advised to
replace a battery that is older than 5 years .
W ith certa in types o f airbag deployment, the
battery is disconnec ted from the vehicle elec
trica l system for safety reasons
c::> &. in Re
pair, care and disposal of the airbags on
page 158.
Disconn ecting the battery terminal s
Some vehicle functions (power w indow regu
l ators, for example) are lost if the battery ter
minals are disconnected . These functions have
to be re learned after the battery terminals are
connec ted again. To prevent this, the battery
should only be disconnected from the vehicle
e lectrical system when absolutely necessary
for repairs .
Vehicles not driven for long period s
If you do not drive your vehicle over a period
of several days or weeks, electrical compo
nents are gradually cu t back or switched off .
This reduces energy consumption and main
tains starting capability over a longer per iod
c::> page 194. Some of the convenience func
tions may not operate, s uch as the inte rior
lights o r power seat adjus tme nt. The conven
i ence functions will be ava ilable again when
you switch on the ignition and start the en gine.
Winter operation
D uring the winter months, ba ttery capaci ty
t ends to decrease as tempe rat ures d rop . This
is because more powe r is also consumed while
starting , and the headlights, rear window de
fogger, etc., are used more often.
Avoid unnecessary power cons umption, par
ticularly in c ity t ra ff ic or when t raveling on ly
short distances. Let your a uthorized Audi
dealer check the capac ity of the vehicle bat
tery before winter sets inc::>
page 233. A well
charged battery w ill not only prevent starting
problems whe n the weather is cold, but will
also last longer .

Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace burned
out bulbs for you .
It is becoming increasingly more and more
difficult to replace vehicle light bulbs since in
many cases, other parts of the car must first
be removed before you are able to get to the
bu lb. Th is applies especia lly to the light bu lbs
i n the front of your car which you can only
reach through the engine compartment ,
Sheet metal and bulb holders can have sharp
edges that can cause ser ious cuts, and parts
must be correctly taken apart and then prop
e rly p ut back together to help prevent break
age of parts and long term damage from wa
ter that can enter housings that have not been properly resealed.
F or your safety, we recommend that you have
your authorized Audi dealer replace any bu lbs
for you, since your dealer has the proper tools, the correct b ulbs and the expertise.
Gas disc harge la mp s (X enon li ght s):
Due to the high electrical voltage, have the
bu lbs rep laced by a qualified technician.
H eadlights with Xenon l ight can be identified
by the high voltage stic ke r.
LED headlights* requ ire no ma intenance .
Please contact your autho rized Aud i deale r if a
bu lb needs to be replaced.
