Trailer mode Driving with a trailer
General information
Your Audi was designed primarily for passenger
transportation .
If you plan to tow a tra iler, p lease remember that
the additiona l load will affect d urability, econo­
my and performance .
T railer towing not on ly places more stress on the
vehicle, it a lso calls for more concentrat ion from
the dr iver .
F or this reason, a lways fo llow the operating and
d riving 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 suitable
for your vehicle and trai ler and must be mounted
securely on the veh icle 's chassis at a technically
sound
location . Use on ly a tra iler hitc h with a re­
movable ba ll mou nt. Always chec k w ith the t ra il­
e r hitch m anu fac tur er to make sure that you a re
using the co rrec t hitch.
Do not use a bumper hitch .
The hitch must be installed in such a way that it
does not i nterfere wit h the impact -absorbi ng
bumper system. No mod ificat ions should b e
mad e to the vehicle exhaust and brake systems .
Fr om time to t ime, c hec k t hat a ll h itch mou nti ng
bo lts remain sec urely fastened .
When you are no t tow ing a trailer,
remove the
trai ler hitch ball mount . Th is prevents the hitc h
fr om caus ing damage should you r vehicle be
s truck from behind~,&. .
Trailer brakes
If yo ur tra iler is equipped w it h a braking system,
check to be s ure that it conforms to all regu la­
tions.
Trailer mode
T he trailer hyd raulic brake system must not be di ­
rect ly connected to the ve hicle's hydraulic b rake
system .
Safety chains
Always use s afe ty chains be tween your ve hicle
and the tra ile r.
Trailer lights
Tra ile r li ghts must meet all regulations. Be sure
to check w it h your Aud i dea le r fo r corr ect w irin g,
swi tches and relays.
Mirrors
If you a re unable to see the traffic behind you us­
i ng the regular o uts ide mirrors, then you
must in ­
sta ll extended mirrors .
It is importa nt that you
always have clea r vision to the rea r.
_&. WARNING
Afte r removing the trailer hit ch, d o no t store
i t in yo ur vehicle. In ca se of sudden br akin g,
the hitch could fly fo rward and inju re you or
your passengers.
Operating instructions
Maximum traile r weight
A trai le r fo r you r vehicle is limited to a typi cal
class 1 or class 2 trai le r.
Trailer load distribution
B e sure the load in the t raile r is held secure ly in
pla ce to p revent it from shift ing forward, back­
ward or sideways .
Never allow a pas senger to ride in a trailer~.&.
in Driving instructions on page 92.
Engine cooling system
Towing a trailer makes the engine work harder . It
is important tha t the cooling system 's pe rform­
ance is up to the additional load. Make s ure that
the coo ling system has enoug h flu id.
Tire pressure
When towing a trailer, inflate the tires of your ve-
hicle to the cold tire pressure listed under "Full
lilJJ..
91

Trailer mode
load" on the label located on the driver's side B ­
pillar (visible when the door is open). Inflate
trailer tires to trailer and tire manufacturers'
specifications.
Lights
Check to make sure both vehicle and trailer lights
are working properly.
Safety chains
Be sure tra iler safety cha ins are properly connect­
ed from the trailer to the hitch on the vehicle.
L eave enough slack in the chains to permit turn­
ing corners. When you install safety chains, make
sure they will not drag on the road when you are
driving .
The chains should cross under the trai ler 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 obta in the best poss ible handling of vehicle
and trailer, please note the following:
.,. Do not tow a loaded tra iler when your car itself
is not loaded.
.. Be especia lly careful 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
Towing a loaded trai ler with an empty car results
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 easie r to operate and control.
This means that the tow vehicle should be loaded
to the extent possible and permissible, while
keeping the trailer as light as poss ible under the
circumstances. Whenever possible, transfer
some cargo to the luggage compartment of the
92
tow vehicle while observing tongue load require­
ments and vehicle loading considerations.
Speed
The higher the speed, the more diff icult it be­
comes for the driver to control the rig. Do not
drive at the maximum permissible speed. Reduce
your speed even more if load, weather or wind
conditions are unfavorab le -particularly when
going downh ill.
Reduce veh icle speed
immediately if the trailer
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 ile rs are lower than fo r regular
vehicles .
Always apply brakes early. When driving down­
hill, shift int o a lo wer gear to use the eng ine
braking effect to slow the vehicle . Use of the
brakes alone can cause them to overheat and fail.
Coolant temperature
The coolant temperature gauge¢ page 12 must
be obse rved carefully. The coolant temperature
can increase if you dr ive on long inclines in a low
gear at high engine speeds . Reduce your speed
immediately if the LEDs in the top part of the dis­
play turn on .
For more information abo ut ind icator lights, re­
fer to. ¢
page 19 .
A WARNING
-
Anyone not properly restrained in a moving
vehicle is at a much greater risk in an acci­
dent. Never let anyone ride in your car who is
not proper ly wearing the restraints provided
by Aud i.
Trailer mode notes
Important to know
Your vehicle handles differently when towing a
trai ler because of the additiona l weight and dif­
ferent weight distribution . Safety, performance
and economy will greatly depend on how careful-
ly you load your trailer and operate your r ig. ..,.

,....,
Before you actually tow your trailer, practice
turning, stopping and backing up in an area away
from traffic. Keep practicing until you have be ­
come completely fami liar with the way your ve hi­
cle-trailer combination behaves and responds.
Backing up is d iff icu lt and requires practice . Back ­
i ng up w ith a trailer generally req uires steering
action oppos ite to that when backing up yo ur ve­
hi cle without a trailer.
M aintain a g reater distance betwee n your vehicle
and the one in front of yo u. You w ill need more
room to stop. To compensate for the tra iler, you
will need a larger than norma l turning radius.
When passing, remember that yo u cannot acce l­
erate as fast as yo u normally would because of
the added load. Make sure you have enough room
to pass. After passing, allow plenty of room for
your trailer before changing lanes again.
Avoid jerky sta rts, sharp turns or rapid lane
changes.
@ Tips
- Do not tow a tra ile r during the break-in peri­
od of yo ur vehicle.
- If yo u tow a t railer, you r A udi may require
more frequent ma intenance due to the ex­
tra load
~ page 262.
Parking on a slope
Do not park on a slope with a trailer . If it cannot
be avoided, do so only after doing the following:
When parking:
.. Apply the foo t brake .
.. Have someone pla ce chocks under bo th t he ve ­
hicle and the trailer wheels .
.. With c hocks i n place, s lowly re lease the brakes
u nti l the whee l chocks absorb the load .
.. Turn the wheels towards the c urb .
.. Apply the parking brake .
.. Se lect the P selector lever pos ition.
When restarting after parking :
.. Apply the foot brake .
.. Start the eng ine.
.. Se lect the D/S selector lever posit ion.
Trailer mode
.. Release the pa rking brake and s lowly pull out
an d away from the wheel chocks .
.. Stop and have someone retr ieve the wheel
chocks.
(D Tips
If you move the selector leve r of the automat­
i c transm iss ion to P before app ly ing the park­
i ng brake and before blocking the wheels, you
may have to use mo re force later to move the
l ever out of the P posit ion.

Parking systems
General information
Applies to vehicles: with rea r parking sys te m s/park in g system
p lus/rearview camera
Depending on your vehicle's equipment, various
parking aids will help you when parking and ma­
neuvering.
The
rear parking system is an audible parking aid
that warns you of obstacles
behind the vehicle
¢ page 116.
The parking system plus assists you when park ­
ing by audibly and visually indicating objects de­
tected
in front of and behind the vehicle
¢ page 116.
The rearview camera shows the area behind the
vehicle in the MMI display. This display assists
you when you are cross or parallel parking. The
parking system plus functions are also available
¢page 117.
A WARNING ,--
- Always look for traffic and check the area
around your vehicle by looking at it directly
as well. The parking system cannot replace
the driver's attention. The driver is a lways
responsible when entering or leaving a park­
ing space and during similar maneuvers .
- Please note that some surfaces, such as
clothing, are not detected by the system.
- Sensors and cameras have blind spots in
which people and objects cannot be detect­
ed . Be especially cautious of small children
and animals .
- Always pay attention to the area around the
vehicle - using the rearview mirror, too.
- The sensors can be displaced by impacts or
damage to the radiator grille, bumper,
wheel housing and the underbody . The park­
ing system may become impaired as a re­
sult . Have an authorized Audi dealer or au­
thorized Audi Service Facility check their
function.
- Make sure the sensors are not obstructed by
st ickers, deposits or other materials.
If they
are the sensor function could be impaired .

@ Note
- Some objects are not detected or displayed
by the system under certain circumstances:
- Objects such as barrier chains, trailer draw
bars, vertical poles or fences
- Objects above the sensors such as wall ex­
tensions
- Objects with specific surfaces or struc­
tures such as chain link fences or powder
snow
- If you continue driving closer to a low-lying
object, it may disappear from the sensor
range. Note that you will no longer be
warned about this obstacle.
- The sensors can be displaced by impacts or
damage to the radiator grille, bumper,
wheel housing and the underbody. The park­
ing system may become impaired as a re­
sult. Have an authorized Audi dealer or au­
thorized Audi Service Facility check their
function.
(D Tips
- The system may provide a warning even
though there are no obstacles in the cover­
age area in some situations, such as:
- certain road surfaces or for long grass .
- external ultrasonic sources e.g. from
cleaning vehicles.
- heavy rain, snow, or thick vehicle exhaust.
- We recommend that you practice parking in
a traffic-free location or parking lot to be­
come familiar with the system. When doing
this, there should be good light and weather
conditions.
- You can change the volume and pitch of the
signals as well as the display¢
page 121 .
-What appears in the MMI display is some­
what time-delayed.
- The sensors must be kept clean and free of
snow and ice for the park assist to operate .

.&_ WARNING
Please note the important safe­
ty precautions regarding tire pressure ¢
page 224 and load
limits¢
page 227.
Tires and vehicle load limits
There are limits to the amount of load or weight that any vehicle
and any tire can carry . A vehicle
that is overloaded will not handle
well and is more difficult to stop .
Overloading can not only lead to
loss of vehicle control, but can al­
so damage important parts of the
vehicle and can lead to sudden
tire failure, including a blowout
and sudden deflation that can
cause the vehicle to crash.
Your safety and that of your pas ­
sengers also depends on making
sure that load limits are not ex­ ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­ cle's
Gro ss Vehicle We ight Rating
("GVWR").
The "GVWR" includes the weight of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids
Tires and wheels
plus maximum load . The maxi­
mum load includes the number of
passengers that the vehicle is in ­
tended to carry ("seating capac i­
ty") with an assumed weight of
150 lbs . (68 kg) for each passen­
ger at a designated seating posi­
tion and the total weight of any luggage in the vehicle . If you tow
a trailer, the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ­ ed as part of the vehicle load.
The
Gross Ax le Weight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two ax les.
T he fact that there is an upper
limit to your vehicle's Gross Vehi ­
cle Weight Rating means that the
total weight of whatever is being
carried in the vehic le (inc luding
the weight of a trai ler hitch and
the tongue weight of the loaded
trailer) is limited. The more pas­
sengers in the vehicle or passen­
gers who are heavier than the
standard we ights assumed mean
that less weight can be carried as luggage.

& WAR NING
-
Overloading a vehicle can cause
loss of vehicle control, a crash
or other acc ident, serious per­
sonal injury, and even death.
-Carrying more weight than your vehicle was designed to carry will prevent the vehicle
from handling properly and in­ crease the risk of the loss of
vehicle control.
-The brakes on a vehicle that
has been overloaded may not
be able to stop the vehicle
within a safe distance .
-Tires on a vehicle that has been overloaded can fail sud­
denly, including a blowout and
sudden deflation, causing loss of control and a crash.
-Always make sure that the to­ tal load being transported -
inc luding the weight of a trail­
er hitch and the tongue
weight of a loaded trailer -
does not make the vehicle
heavier than the vehicle's
Gross Vehicle Weight Rating.
228
Determining correct load
limit
Use the example below to calcu­
late the total weight of the pas­
sengers and luggage or other
things that you plan to transport so that you can make sure that
your vehicle will not be overload ­
ed.
Step s for Determining Correct
Load Limit
1. Locate the statement "THE
COMBINED WE IGHT OF OCCU ­
PANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR XXX
L BS"on your vehicle's placard
(tire inflation pressure label)
¢ page 224, fig . 170 .
2. Determine the combined
weight of the drive r and pas­
sengers that will be riding in
your vehic le.
3. Subtract the combined weight of the driver and passengers
from "XXX" kilograms or "XXX"
pounds shown on the sticker
¢ page 224, fig . 170 .
4. The resulting figure equals the
available amount of cargo and luggage load capacity . For ex­
ample, if the
"XXX" amount
equals 1400 lbs . and there will ...

M N
0 > co ,...., \!) 1.1'1

,....,
be five 150 lbs. passengers in
your vehicle, the amount of
available cargo and luggage load capacity is 650 lbs.
(1400-750 (5
X 150) = 650
lbs.)
5. Determine the combined weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely
ex­
ceed the available cargo and
luggage load capacity calculat­
ed in Step 4.
6. If your vehicle will be towing a trailer, load from your trailer
will be transferred to your vehi­
cle. Consult this manual to de­
termine how this reduces the available cargo and luggage
load capacity of your vehicle.
.,.Check the tire sidewall
(c> page 214, fig. 168) to deter­
mine the designated load rating
for a specific tire.
Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/tighten
easily.
Rims
Rims with a bolted rim ring* or with bolted wheel
covers* consis t of mul tiple pieces. These compo­
nents were bolted together using special bolts
and a special procedure . You must not repair or
disassemble them
Q ,& .
Tires and wheels
A WARNING
Wheel bolts that are tightened or repaired in­
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident . For the correct tightening specifi­
cation, refer to~
page 242, A~er changing a
wheel.
- Always keep the wheel bolts and the threads
in the wheel hub clean and free of grease.
- Only use wheel bolts that fit the rim.
-Always have damaged rims repaired by an
authorized Audi dealer or authorized Audi
Service Facility. Never repair or disassemble
rims yourself, because this increases the risk
of an accident.
Winter tires
Winter tires significantly improve the vehicle's
handling when driving in winter conditions. Be­
cause of their construction (width, compound,
tread pattern), summer tires provide less traction on ice and snow.
.. Use winter tires on all four wheels.
.. Only use winter tires that are approved for your
vehicle .
.. Please note that the maximum permitted
speed may be lower with winter tires
Q _& . An
authorized Audi dealer or authorized Audi Serv­
ice Facility can inform you about the maximum
permitted speed for your tires.
.. Check the tire pressure after installing wheels
Qpage 224.
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0.157 inch (4 mm). The characteristics of winter
tires also decrease greatly as the tire ages, re­
gardless of the remaining tread.
A WARNING
-Never drive faster than the maximum per­
mitted speed for your tires. This could cause
the tires to heat up too much. This increases
the risk of an accident because it can cause
the tire to burst.

nance booklet .
Under difficult operating conditions, for exam­
ple at extremely low outs ide temperatures, in
very dusty regions, when towing a trailer very fre­
quently , etc., some service work should be per­
formed between the intervals specified. This ap­
plies particularly to:
- oil changes, and
- cleaning or replacing the air filter .
