Description
App lies 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 warning tone will sound as soon as your speed
exceeds the stored value slightly. The
(Ol (USA
models)/
(01 (Canada models) indicato r light
and a message appear i n the ins trumen t cluster
d isplay at the same time. The
(Sl (USA models)/
(O] (Canada models) indicator light and the mes ­
sage turn off when the ve hicle speed drops below
the stored maximum speed.
Sett ing a threshold is recommended if you would
like to be reminded when you reach a certain
maximum speed . Situations where you may want
to do so include driving in a country with a gener­
al speed limit or if there is a specified maximum
speed for winter tires.

fe rent types of vehicle settings in one vehicle.
The driver can select from three modes, Comfort,
Auto and Dynamic , using the
i:l:ta button in the
center console or by using the Infotainment sys­
tem . T his allows you to switch between a sporty
and a comfortab le driving mode, for examp le. In
the Indi vidual mode, the settings can be adjust­
ed to your personal preferences. This makes it
possible to combine sett ings such as a sporty en­
g ine setting w ith light steering.

The veh icle setup in each mode depends on the
vehicle's features.
Engine and automatic transmission
Depending on the mode, the engine and auto­
matic transmission respond more quickly or in a
more balanced manner to accelerator pedal
movements.
Suspension control (Audi magnetic ride)*
The suspension control uses sensors to record in­
format ion regarding steering movements, brak­
i ng and acceleration operations by the driver, as
well as information about the road surface, driv­
i ng speed, and load. W ith dr ive se lect, you can
adjust the suspension control to sporty (dynam­
ic ), comfortable (comfort) or balanced (auto).
Steering
The power steering adapts . Indirect steering that
moves eas ily as in comfort mode is espec ially
su ited to long drives on a highway . The dynamic
mode provides sporty, direct steering.

Brakes
New brake pads
New brake pads do not achieve their full braking
effect d uring the first 250 mi (400 km) . They
must be "broken in" first . Howeve r, you can com­
pensate fo r th e slig htly reduced b raking force by
pressing fi rm ly on t he b rake ped al. Avo id heavy

-The efficiency of the brakes can also be im­
paired by driving for long stretches on roads
covered with salt without using the brakes .
You can remove salt deposits from the
brake rotors and pads by carefully applying
the brakes severa l t imes .
- If the front spoiler is damaged or you install
another spoiler, make sure the front wheel
brakes are vent ilated proper ly . Otherwise,
the b rake system could overheat, w hich re­
duces the ir effectiveness.
- Failure of a brake c ircuit impa irs b raking
perfo rman ce , which increases brak ing dis ­
tan ce. Avoid d riving the vehicle and have it
towed it to the nearest authorized Audi
dealer or authorized Audi Service Facility .
- Never let the vehicle roll while t he engine is
stopped because this increases the risk of an
accident.
- If the brake booster is not working, you will
have to press much harder on the brake
peda l to compensate for the lack of the
booster.
@ Note
- Never let the brakes "rub" by pressing the
pedal light ly when braking is not actually
necessary. This causes the brakes to over­
heat and increases braking d istance and
causes wear.
- Before driving downhi ll a long distance on a
steep h ill, decrease your speed and select a
lower gear. This makes use of the engine
braking effect and relieves the brakes . If
you need to brake additionally, brake in in­
tervals and not conti nuous ly .
0) Tips
- If the brake booster is not working, you
must press the brake pedal with much more
fo rce t han normal.
- If you retrofit your vehicle with a front spoil­
er, whee l covers o r similar items, make sure
t h at the a ir flow to the front whee ls is not

If the indicator l ight turns on, the steering wheel
may be more d ifficult to move or more sensit ive
t h an usual. The steer ing whee l may also be at an
angle when d riving stra ight.
Drive slowly to an authorized Aud i dealer or au­
thorized Aud i Serv ice Facility to have the mal­
funct ion corrected.

fo r a short t ime, yo u may continue d riving.
All wheel drive (quattro)
In all wheel drive, all four wheels are powered.
Gener al informat ion
In all wheel dr ive, the dr iving power is divided be­
tween all four wheels . This happens automatical ­
ly depending on your dr iv ing behavior as well as
t h e cur rent road condit ions. A lso

snow and ice. Always read and follow safety pre­
cautions
¢ .&. .
Winter tires
By using all wheel drive, your vehicle has good
forward motion with standard tires in winter con­
ditions. However, in winter we recommend using
winter or all season tires on
all four wheels, be­
cause this will improve the
broking effect.
Snow chains
If there are snow chain laws, snow chains must
also be used on vehicles with all wheel drive
c::> page 259, Snow chains.
Replacing tires
For vehicles with all wheel drive, only wheels with
the same rolling circumference should be used .
Avoid using tires with different tread depths
c::> page 251, New tires or wheels.
Offroad vehicle?
Your Aud i is not an offroad vehicle - there is not
enough ground clearance. For this reason, avoid
difficult terrain.
,& WARNING
- Also, in vehicles with all wheel drive, adapt
your driv ing style to the current road and
t ra ffic conditions. Do not let the increased
safety provided tempt you into taking risks,
because this increases the r isk of an acci­
dent.
- The braking ability of your vehicle is limited
to the traction of the wheels. In this way, it
is not different from a two wheel drive vehi­
cle. Do not be tempted to accelerate to a
high speed when the road is slippery, be­
cause this increases the risk of an accident.
- Note that on wet streets, the front wheels
can "hydroplane" if driving at speeds that
are too high. Unlike front whee l drive
vehicles, the engine does not rev higher sud­
denly when the vehicle begins hydroplaning.
For this reason, adapt your speed to the
road conditions to reduce the risk of an acci­
dent.

on the vehicle speed.
A WARNING
-
Driving at higher speeds without the rear
spoiler deployed can impair handling charac­
teristics, making the vehicle harder to con­
trol.
- Always make sure that the spoiler is de­
ployed when driving at speeds over 85 mph
(140 km/h) . If the rear spoiler warning/ind i­
cator lig ht in the instrument cluste r comes
on, the rear spoiler may not have deployed.
- Never drive at speeds higher than 85 mph
(140 km/h) if the spoile r is not deployed.
Have the spo iler inspected as soon as possi ­
ble by an author ized Audi dealer or qua lified
works hop .
- Always obey speed l imits and othe r traffic
laws .
A WARNING
Improper operation of t he rear spoiler can
cause crushing injuries.
- Always make sure that nobody, especia lly
children, is in the way when the rear spoi ler
is deployed or retracted .
(Llj) Note
-Never push on the vehicle on the rear spo il­
er. This cou ld cause damage.
- To p reve nt damage to the rear spoiler do
not lean o r place anyt hing on it.

- Only ope rate the rear spoiler manually when
the luggage compartment lid is close and
the rear spoiler mov ing parts are not
blocked. Otherwise, damage could occur .
(j) Tips
Clean the rear spoiler compartment eve ry 2 to
3 months . To function co rrectly, the rear
spoiler must be free of ice, snow and leaves .
Intellig ent T echn olo gy
Energy management
Your vehicle is equipped with an intelligent ener­
gy management system for distributing electrici ­
ty. This significantly improves the starting ability
and increases the vehicle battery life.
(D Tips
- If you drive short distances frequent ly, the
vehicle battery may not charge enough
wh ile driving. As a result, convenience func­
tions for electr ical equipment may be tem­
pera rily unavailable .
- The vehicle battery w ill gradually drain if
the vehicle is not driven for long per iods of
t ime, or if electr ical equ ipment is used
when the engine is not runn ing. To ensure
that the veh icle can still be started, the
elect rical eq uipment w ill be red uced or
sw itched
off.
Information about data
recorded by vehicle
control modules
Your vehicle is not equipped with a crash data re­
corder . This dev ice is installed by some veh icle
manufacturers to record data about crashes so
t h at it can be ana lyzed later. Crash data reco rd ­
ers are also called " Event Data Recorders (EDR)".
In some legal jurisdictions, it is not permitted to
access or down load data recorded by pre-instal­
led crash data recorders in orde r to evaluate a
crash without clear consent of the vehicle owner.
Your vehicle is not equ ipped w ith a crash data re­
corder . However it does contain a variety of e lec­
tronic control modules for various vehicle sys­
tems such as engine function, exha ust treatment
or airbags and safety belts.

Checking and Filling Fuel
Gasoline grade
The correct gasoline grade is stated on the inside
of the fuel filler door .
The vehicle is equipped with a catalytic converter
and must only be driven with
unl ead ed g asoline.
Audi recommends using TOP TIER Detergent Gas­
oline. Additiona l information on TOP TIER Deter­
gent Gasoline can be found on the offic ial web­
site (www .topt iergas.com).
The individua l gasoline grades are differentiated
by
oc ta n e ra ting s. This value is given with (R +M)/
2 equating to AKI or in RON.
The fo llowing headings match the corresponding
sticker in the fuel fi ller door .
UNLEADED FUEL ONLY MIN. (R+M )/2 8 7
R egula r/ MIN. RON 91 Regula r
Use regu la r gasoline with minimum 87 AKI/
91 RON ~ (Di .
The max imum engine power is only reached if
prem ium gaso line 91 AKI/ 95 RON is used.
UNLEADED FUEL ONLY PREMIUM MIN . (R
+M )/2 91 / SUPER MIN. RON 95
Using prem ium gaso line with minimum 91 AKI/
95 RON is recommended.
If premium gasoline is not available, you can also
use regula r gasoline 87 AKI/ 91 RON . However
this does reduce the engine powe r sli ght ly.
{LlJ) Note
- Fill ing the tank just one t ime with leaded
fuel or other meta llic additives wi ll cause
permanent deter io rat ion to the catalyt ic
conve rter function.
- When gasoline with an octane rat ing that is
too low is used, h igh speeds o r heavy eng ine
l oad can lead to eng ine damage.
Ch eck ing and F illing
(D Tips
The vehicle may be filled with fuel that has a
higher octane rating than what is requ ired by
the engine .
Blended gasoline
U se of g asoline cont aining alcohol or MTBE
( m eth yl tertiary butyl ether )
You may use unleaded gasoline blended with al­
cohol or MTBE (commonly referred to as oxygen­
ates) if the blended m ixture meets the fo llow ing
c riter ia:
Blend of ga soline me thanol ( wood alc ohol or
meth yl alcoh ol)
-Anti-knock index must be 87 AKI or h igher.
- Blend must contain no more than
3% metha-
nol.
- Blend must contain more than
2% co-solvents.
Blend of g asoline a nd eth ano l (g ra in a lcoh ol o r
eth yl alc ohol )
-Anti-knock index must be 87 AK I or h igher.
- Blend must not conta in more than
15% etha-
nol.
Blend of g asoline and MTBE
- Anti -knock index must be 87 AKI or higher.
- Blend must not contain more than
15% MTBE .
Seasonally a djust ed g aso lin e
Many gasoline grades are blended to perform es­
pecially well for winter or summer dr iving . Dur­
i ng seasonal change-over, we suggest that you
fill up at busy gas stat ions where the seasonal
adjustment is mo re likely to be made in t ime .
@ Note
-Methano l fuels which do not meet these re­
quirements may cause cor rosion and dam­
age to p lastic and rubbe r components in the
fue l system.
- Do not use fuels that fa il to meet the speci­
fied cr ite ria in t his chapter.
229

Checking and Filling
-If you a re unable to determine whether or
not a particular fuel blend meets the speci­
fications, ask your service station or its fuel
supplier.
- Do not use fuel for which the contents can­
not be identified.
- Fuel system damage and performance prob­
lems resulting from the use of fuels differ­
ent from those specified a re not the respon­
sibility of Audi and are not covered under
the New Vehicle or the Emission Control System Warranties.
- If you experience a loss of fuel economy or
driveability and performance problems due
to the use of one of these fuel blends , we
recommend that you switch to unblended
fuel.
Gasoline additives
A major concern among many auto manufactur­
ers is carbon deposit build-up caused by the type
of gasoline you use.
Although gasoline grades differ from one manu­
facturer to another, they have certain things in
common. All gasoline grades contain substances
that can cause deposits to collect on vital engin e
parts, such as fuel injectors and intake valves. Al­
though most gasoline brands include additives to keep engine and fuel systems clean, they are not
equally effective .
Audi recommends using TOP TI ER Dete rgent Gas­
oline. For more information on TOP TIER Deter­
gent Gasoline , please go to the official website
(www .toptiergas .com) .
After an extended per iod of us ing inadequate
fuels, carbon deposit build-ups can rob your
en­
gine of peak performance.
(D Note
Damage or malfunction due to poor fuel qual­
ity is not covered by the Audi New Vehicle Limited Warranty.
