tires to trailer and tire manufacturers' specifica­
tions.
Lights
The headlight settings should be checked with
the trailer attached before driving off. Check to
make sure both vehicle and trailer lights are
working properly.
Safety chains
Be sure trailer safety chains 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 cha ins shou ld cross under the trailer tongue
to prevent it from dropping in case of separat ion
from the hitch.
Driver messages
Driving with a trailer requires extra caution.
Weight distribution
Towing a loaded trailer with an empty car results
in a high ly unstable distribution of weight .
If this
cannot be avo ided, drive at very low speeds only
to avoid the risk of losing steering control.
A "balanced" rig is easier to operate and control.
This means that the tow vehicle should be loaded to the extent possible and permissible, whi le
keep ing the trailer as light as possible under the
circumstances . Whenever possible, transfer
some cargo to the luggage compartment of the
tow vehicle whi le observ ing tongue load require­
ments and vehicle loading considerations.
Speed
The highe r the speed, the more difficult 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 unfavorable
-particularly when
going downhill.
Tra iler towing
Reduce vehicle 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 trailers are lower than for regular
vehicles .
Always apply brakes early. When driving down­
hill, shift into a lower gear to use the engine
braking effect to slow the vehicle . Use of the
brakes alone can cause them to overheat and fail.
Coolant temperature
T he coo lant temperature gauge ~ page 11 must
be observed carefully. The coolant temperature
can increase if you drive 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 about indicator lights, re­
fer
to . ~page 30 .
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 properly wearing the restraints provided
by Aud i.
Trailer towing
information
Important to know
-
Your vehicle handles differently when towing a
trailer because of the addit ional weight and dif­
ferent weight distribution . Safety, performance
and economy will greatly depend on how careful­
ly you load your trailer and operate you r rig.
Before you actually tow your trailer, pract ice
turning, stopping and backing up in an area away
from traffic . Keep pract ic ing until you have be­
come complete ly familiar w ith the way your vehi­
cle-trailer combination behaves and responds.
105

Trailer towing
Backing up is difficult and requires practice .
Backing up with a trailer generally requires steer­
ing action oppos ite to that when backing up your
veh icle w ithout a trailer.
Maintain a greater distance between your vehicle
and the one in front of you. You w ill need more
room to stop. To compensate for the tra iler, you
will need a larger than normal turn ing radius.
When passing, remember that you cannot accel ­
erate as fast as you norma lly would because of
the added load. Make sure you have enough room
to pass. After passing, allow plenty of room for
your tra iler before chang ing lanes again.
Avoid jerky starts, sharp turns or rapid lane
changes .
@ Tips
- Do not tow a trailer during the break -in per i­
od of your vehicle.
- If you tow a trailer, your Audi may require
more frequent maintenance d ue to the ex­
tra load
~ page 389.
Parking on a slope
Do not pork on a slope with a trailer. If it cannot
be avoided, do so only
o~er doing the following:
When parking:
.,. Apply t he foo t brake .
.,. Have someone place chocks under both t he ve­
hicle and the tra ile r whee ls .
.. With chocks in p lace, slowly release t he brakes
u ntil the whee l chocks absorb the load .
.. Turn the wheels towards the curb .
.. Apply the parking brake .
.. Move the selector lever to P (automat ic trans­
mission) respectively select first gear (manual
transm iss ion).
When restarting after parking:
.. Apply the foot brake .
.. Start the engine .
.. Applies to: vehicles with automatic transmis­
sion: Move the selector lever to D/S .
.,. Release the parking brake a nd slowly pull out
and away from the wheel chocks.
106
.. Stop and have someone retrieve the whee l
chocks.

Assistance systems Electronic speed limiter
Your vehicle may be factory equipped with t ires
that are rated for a maximum speed of 130 mph (210 km/h). This is less than the maximum speed
of your vehicle. To reduce the risk of sudden tire
failure and loss of control if the vehicle is operat­
ed at excessive speeds, your vehicle also has an
electronic speed limiter . The electronic speed
limiter prevents your vehicle from going faster
than the t ire speed rating. For mo re information
~page 341.
If the engine control unit receives faulty vehicle
road speed s ignals, the Malfunction Indicator
L amp
(MIL) ¢..ij will illuminate. If this occurs,
contact the nearest autho rized Audi dealer for
assistance.
_& WARNING
Always observe the posted speed limits and
adjust your speed to suit prevailing road, traf­
fic and weather conditions. Never drive your
vehicle faster than the max imum speed rating
of the tires installed.

Introduction
Applies to: vehicles with speed warning system
The speed warning system helps you to stay be­
low a specified maximum speed that can be set,
changed or deleted in the Infotainment system.
-
The speed warning system warns you if you are
exceeding the maximum speed that you have set .
A wa rning tone will sound as soo n as yo ur speed
exceeds the s tored value sligh tly. The
[01 (USA
models)/
[01 (Canada models) indicator light
and a message appear in the instrument cluster
display at the same time. The
HI] / [0] indicator
light and the message turn off if the speed falls
back below the stored maximum speed.
Setting a threshold is recommended if you would l ike to be reminded when yo u reach a certain
maximum speed. Situations where you may want
to do so include driving in a country with a gen er-
Ass is ta nce syst ems

Description
Applies to: vehicles with Audi drive select
The following systems, among other things, are
influenced by drive select:
Engine and automatic transmission*
Depending on the mode, the engine and auto­
mat ic transmission* respond more quickly or in a
more balanced manner to accelerator pedal
movements. In the sporty
Dynamic mode, the
transmission shifts at highe r speed ranges.
Suspension control*
The suspension control* uses sensors to record
information regarding steering movements,
braking and acceleration operations by the driv­
e r, road sur face, dr iv ing speed, and load. This
makes it possible to adapt damping to the driv­
ing situation nearly in rea l time. With drive se ­
lect, you can adjust the suspension control to be
sporty
( Dynamic ), comfortab le ( Comfort ) or bal­
anced
( Auto ).
Steering
The power steering adapts. Indirect steer ing that
moves easi ly as in
Comfort mode is especia lly
suited to long drives on highways. The
Dynamic
mode provides sporty, direct steering.
The following applies to vehicles with dynamic
steering*: the steering ratio changes based on
vehicle speed in order to maintain optimum
steering effort for the driver at all times. This
sets the steer ing to be less sensitive at higher
speeds in order to provide improved vehicle con­
trol. At reduced speeds, steering is more direct in
order to keep the steering effort as min imal as
possible w hen the driver is maneuvering the vehi­
cle . At low and average speeds, dynam ic steer­
in g* add itionally provides more responsive steer­
ing performance.
Sport differential*
As a component of the all wheel drive system
(quattro)
~ page 154, the sport differential dis­
tr ibu tes the dr iv in g power to the rear ax le de­
pending on the situation. The distribution of
power varies depending on the selected mode
Assistance systems
from moderate (Comfort ) to sporty (Dynamic ).
The goal is a high level of agility and ability to ac­
ce lerate on curves . T he vehicle is very responsive
to steering.
Adaptive cruise control (ACC)*
The behavior when accelerating can be adjusted
from comfortable to sporty, depending on the
drive select mode. Adaptive cruise control also
responds to the driving behavior of the vehicle
ahead in a more conservative or sporty manner.
Engine sound*
The engine sound adapts to the current mode
and can be subtle to sporty.
(D Tips
The S selecto r lever position automatically en­
gages when the
Dynamic mode is selected .
Selecting the driving mode

You should only switch sport mode on or switch ESC/ASR off if your driving abilities
and road conditions permit .
- The stabilization function is limited when

Brakes
New brake pads
New brake pads do not ac hieve the ir full b raking
effect during the first 250 mi (400 km) . They
must be "broken
in " fi rst . However, you can com­
pensate for the slightly reduced bra king fo rce by
pr ess ing firmly o n the bra ke pe dal. Avoid heavy
b ra king dur ing t he b reak -in per io d .
Wear
Brake pad wear depends largely o n the way the
ve hicl e is driven and on operat ing cond it ions .
This is especially t rue if you are d riving freque ntly
in t he c ity and on curves o r wi th a sporty driving
s tyle.
Operating noise
Noises may occur when braking depend ing o n the
speed , braking force and ou ts ide cond it ions such
as te m pe ra ture and humi dity .
Wet conditions or road salt
In certain situations, for example after driving
through water, in heavy ra in or after washing
your car, the braking ef fect may be reduced due
to mo isture or ice on the b rake roto rs and b rake
pads. The b rakes mus t be
"dried" firs t wi th a few
care ful bra ke app lic at ions.
At higher speeds and with t he windsh ie ld wipers
turned o n, the brake pads press against the bra ke
rotors for a s ho rt amoun t of time. This ac tion,
whi ch is not felt by the driver , happens at regul ar
i nte rvals an d ens ures a better reac tion time fo r
the brakes in wet weat her.
Intellig ent Technology
The brak ing effec t can a lso be reduced if yo u are
driving on salted roads and yo u do not app ly the
bra kes for long per iods o f time. The layer of sa lt
on the brake rotors and pads m ust be worn off
first whe n the brakes are applied .
Corrosion
Leaving t he vehi cle pa rked for long periods o f
time, low mileage and avoiding heavy b raking
can contrib ute to corros ion on the b rake roto rs
and to dirty brake pads.
If you usu a lly avoid heavy bra king or if there is
cor rosion prese nt, occasiona l heavy braking at
high speeds is recommended to clean the brake
roto rs and pads
c> ,& .
Brake system malfunction
If you notice that the bra ke pedal trave l has sud ­
denly in crease d, then a brake circuit in the dua l­
circuit b rake system may have malfunctioned.
Drive to an authorized A udi dealer or authorized
Audi Se rvice Facility immed iate ly to have the
problem corrected. On the way there, d rive w ith
reduced speed and keep in mind that you will
need a longer distance to stop and you will need
to press the bra ke ped al ha rder.
Low brake fluid level
When the bra ke fluid level is low, malfu nctions in
the b rake system may occur . T h e brake fluid level
is e lec tron ically moni tored.
Brake booster
The brake booster ampli fies t he p ressure you ap­
ply to the brake pedal.
A WARNING
- On ly app ly the brakes for the purpose of
cleaning the brake system when road and
traffic cond itions permi t. You must not en ­
da nger other road users. This inc reases the
ris k of an a ccid en t.
- Never let the vehicle roll while the engine is
sto pped bec ause t his increases the risk of an
a ccident.
