Trailer towing
Trailer towing
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, economy and performance.
Trailer towing not on ly places more stress on the
ve hicle, it also ca lls for more concentration from
the dr iver.
F or this reason, always follow the operating and
driving instructions provided and use common
sense.
@ Note
If you are going to tow a trailer, you must ac
tivate the tra ile r operation mode
¢page 100.
Technical requirements
Traile r hitch
Use a weight-carrying hitch conforming to the
gross trai ler weight. The hitch must be suitab le
for your ve hicle and tra iler and must be mounted
securely on the vehicle 's chassis at a
technically
sound
locat ion . Use on ly a trailer hitch with a re
movable ba ll mount . Always chec k w it h t he t rail
er hitch man ufactur er to make s ure t hat you a re
using the co rrect hi tc h.
Do not use a bumper hitch.
The hitch m ust be installed i n such a way that it
does not interfere with the impact -absorbing
bumper sys tem . N o mod ificat ions should be
made to the vehicle exhaust and b rake systems .
Fr om t ime to t ime, che ck t hat all hitch mo unti ng
bol ts rem ain securely faste ned.
W hen you are not tow ing a tra iler, remove the
tra ile r hitc h ba ll mount . This prevents the hitch
from ca using damage shou ld your veh icle be
s truck from behind¢ &..

Trailer brakes
If your trailer is equipped wi th a bra king sys tem,
c h ec k t o be sure that it con forms to all regu la
tions.
The trailer hydrau lic br ake system mus t not be
directly connecte d to the vehicle's hydr auli c
brake system ¢&. .
Safety chains
Always use safety chains between your vehicle
and t he tra ile r.
Trailer lights
Trailer lights must meet all regulations. Be sure
to check w ith your author ized Audi dealer for cor
r ect wir ing , sw itches and relays .
Mirrors
If you are unab le to see the traffic behind you us
i ng the regular outs ide mirrors, then you
must in
stall extended mirro rs. It is important that you
always have clear vision to the rear.
A WARNING
-
- After remov ing the tra iler hitch, do not
sto re it in your vehicle . In case of sud den
braking , th e hitch co uld fl y forwar d and i n

room to stop. To compensate fo r the tra iler, yo u
will need a larger than normal turn ing rad ius.
When pass ing, remember t hat you cannot accel
erate as fast as you norma lly wou ld because of
the added load. Make s ure you have eno ugh room
to pass. After passing , allow plenty of room fo r
your tra iler before changing lanes again.
Avoid jerky starts, s harp turns or rapid lane
changes .
(D Tips
-Do not tow a trailer during t he br ea k-in per i
o d of yo ur vehicle .
- If you tow a trailer, your Audi may require
more frequent maintenance due to the ex
tra load

Parking on a slope
Do not pork on o slope with o trailer . If it cannot
be avoided, do so only ofter doing the following:
When parking:
" Apply the f oot brake.
" Have someone p lace chocks under both the ve
hicle and the tra il e r whee ls .
" Wi th chocks in p lace, slowly release t he b rakes
u nti l the w hee l chocks absor b the load.
" Turn the wheels towa rds the curb.
" Apply the pa rking brake.
" Move the se lector lever to P .
When restarting after parking:
"Apply the foot b rake.
" Start the engine .
" Move t he se lecto r lever to D/S.
" Release the parking brake and slowly pull out
and away from t he whee l chocks.
" Stop and have someone retrieve t he wheel
chocks .

Electronic stabilization
control (ESC)
Description
Elect ronic stabilization control (ESC) supports
driver safety.
It red uces the risk of slipping and
improves driving stability. ESC detects crit ica l sit
uations such as when the vehicle is oversteering
and understeering or the wheels are spinning.
The vehicle is stabilized by applying the brakes or reducing eng ine torq ue. When the ESC engages,
the
DJ ind icator light blinks in the instrument
cluste r.
The fo llow ing systems are integrated in the ESC:
Ant i-loc k bra king system (ABS)
ABS prevents the whee ls from locking when brak
ing. The vehicle can sti ll be steered even during
hard brak ing. Apply steady pressure to the brake
pedal. Do not pump the pedal. A puls ing in the
brake pedal indicates that the system is acting to
stabilize the vehicle .
Brake assist system
The brake assist system can decrease brak ing dis
tance . It increases braking power when the driver
presses the brake pedal quick ly in emergency sit
uations . You must press and hold the b rake pedal
until the dangerous situat io n is over . In veh icles
with adapt ive cr uise control*, the bra ke assist
sys tem is more sensitive if the d ista nce detec ted
t o the vehicle dr iv ing ahead is too small.
O n ve hicles w ith act ivated and funct io ni ng night
vision assist*, the brake ass ist system ca n re
spond more sens it ively if there is a warning.
Anti-Slip Regulation (ASR )
ASR reduces eng ine power when the drive wheels
begin spinning a nd adap ts the force to the road
conditions . This makes it easie r to start, acceler
ate and dr ive up h ills.
Electron ic differential lock (EDL )
EDL applies the brakes to a wheel that starts
spinning and transfers the drive power to the
148
other driving whee ls. This function is not avai la
ble at higher speeds.
In extreme cases , ED L automat ica lly swi tches off
to keep t he b rake on the braked wheel from over
heating. The veh icle is still working correct ly. ED L
will switch on again automatically when condi
tions have returned to normal.
Steering recommendat ion
The ESC he lps to stabilize the vehicle by chang ing
t h e s teer ing torque.
Select ive wheel torque control
Se lective wheel to rque cont rol is used when d riv
i ng on curves. Braking is targeted toward the
whee ls on the inside of the curve as needed . T his
a ll ows mo re precise dr iving in cu rves .
Automatic post -collision braking system
The "automat ic post -collis io n braking system"
can help to reduce the risk of sliding and of addi
tiona l co llisions after an acc ident. If the a irbag
contro l modu le detects a collision, the veh icle is
braked by the ESC.
The veh icle does not brake automatically if:
- the driver presses the accelerator pedal, or
- the ESC, the brake system or the veh icle elect ri-
cal system are not functioning.
A WARNING
- The ESC and its integrated systems cannot
overcome the lim its imposed by natura l
phys ical laws . This is espec ially important
on s lippery or wet roads . If the systems be
gi n ac ting to stabilize yo ur vehicle, you
should immediately a lter your speed to
match the road and traffic conditions. Do
not let the inc reased safety provided tempt
you into taking risks. This could increase
your r isk of a coll is ion.
- Please note the risk of a collision increases
when driving fast, especially through curves
and on slippery or wet roads, and when dr iv
ing too close to objects ahead. The ESC and
its integrated systems cannot always pre
vent co llisions -there is st ill a risk of acci
dents!

Driving sa fe ty
Loose items in the luggage compartment can
shift s udden ly, changing vehicle handling charac
ter istics . Loose items can also increase the risk of
serious personal in jury in a sudden vehicle ma
neuver or in a coll is ion.
.,. Distribute the load evenly in the luggage com
partment .
.,. Always place and properly secure heavy items in
the luggage compartment as low and as far for
ward as possible
c> fig . 226 .
.,. Secure luggage us ing the tie-downs provided

.,. Make su re that the rea r seatbac k is securely
latched in place .
A WARNING
Improperly stored luggage or othe r items can
fly through the vehicle causing serious per
sonal injury in the event of hard braking or an
accident . To help reduce the risk of serious
personal injury :
- Always put objects, for example, luggage or
other heavy items in the luggage compart
ment.
- Always sec ure objects in the luggage com
partment using the tie-down eyelets and
s u itable straps.
A WARNING
Heavy loads will influence the way your vehi
cle handles . To he lp reduce the r isk of a loss
of contro l leading to serious pe rsonal i njury:
- Always keep in mind when transporting heavy objects, that a change i n the center of
grav ity can also cause changes in vehicle
hand ling:
- Always distr ibute the load as even ly as
possible.
- Place heavy objects as far forward in the
luggage compartment as poss ible.
- Never exceed the Gross Axle Weight Rating
o r the Gross Vehicle Weight Rating specified
on the safety compliance sticker on the driv
er's side B-pillar. Exceeding permiss ible
weight standards can cause the vehicle to
s lide and handle differently .

-Please observe info rmation on safe driving
¢page 256 .
A WARNING
To he lp prevent po isonous exhaust gas from
being drawn into the vehicle, always keep the
rear lid closed while driving.
- Never transport objects larger than those
fitting completely into the luggage area be
cause the rear lid cannot be fully closed .
- If you absolutely must dr ive with the rear lid
open, observe the following notes to reduce
the risk of poisoning :
- C lose all windows,
- Close the s unroof*,
- Open all a ir outlets in the instrument pan-
el,
- Switc h off the air reci rculat ion,
- Set the fresh air fan to the highest speed .
A WARNING
-
Always make sure that the doo rs, all win
dows, the sunroof * an d the rear lid are se
curely closed and locked to red uce the risk of
i n jury when the veh icle is not being used.
- After closing the rear lid, always make sure
that it is properly closed and locked .
- Never leave your ve hicle unattended espe
cially with the rear lid left open. A child
co uld crawl into the vehicle th rough the lug
g age com partment an d close the rea r lid be
comi ng tr apped and unab le to ge t out . Be
ing trapped in a vehicle can lead to ser ious
pe rsonal i nju ry.
- Never let c hild ren p lay in or around the vehi
cle.
- Never let passengers ride in the luggage
compa rtment. Vehicle occupants mus t al
ways be p roperly restrained in one of the ve
hicle's seat ing pos itions.
(D Tips
- Air circul ation helps to reduce w indow fog
ging . Stale ai r escapes to the o uts ide
t h roug h vents in the trim panel. Be sure to
keep these slots free and open.
Safe ty belts
passenge rs, a lways correct ly wear safety
belts when the vehicle is moving.
- Failure to pay attention to the warning light
that comes on could lead to personal injury.
Why use safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for peo
ple riding in vehicles .
Fig. 2 28 Unbe lt ed occupants in a vehi cle headi ng for a wall
Fig . 229 T he ve hi cle c rashes into the wa ll
The physical principles are simple . Both the vehi
cle and the passengers possess energy which var ies w ith vehicle speed and body weight . Engi
neers call this energy "k inetic energy."
The higher the speed of the vehicle and the
g reater the vehicle's weight, the more energy
that has to be "absorbed" in the crash.
Veh icle speed is the most signific ant fac tor .
If
the speed doubles from 15 to 30 mph (25 to 50
km/h) , the energy increases 4 t imes!
Because the passengers of th is veh icle are not us
i n g safety belts~
fig. 228, they will keep mov ing
at the same speed the ve hicle was mov ing j ust
266
before the crash, until something stops them -
here, the wall¢
fig. 229 .
The same principles apply to people s itting in a
vehicle that is invo lved i n a frontal collision . Even
at city speeds of 20 to 30 mph (30 to 50 km/h),
the forces acting on the body can reach one ton
(2,000 lbs . or 1,000 kg) o r more. At g reater
speeds, these forces are even higher.
People who do not use safety belts are a lso not
attached to their vehicle. In a frontal collision
they will also keep mov ing forward at the speed
their vehicle was travelling just before the crash. Of course, the laws of physics don 't just apply to
frontal collisions , they determine what happens
i n a ll kinds of accide nts and co llisions .
What happens to occupants not wearing
safety belts?
In crashes unbelted occupants cannot stop
themselves from flying forward and being in
jured or killed . Always wear your safety belts!
