Driving
-If physica l limitations prevent you from sit­
t ing 10 in (25 cm) or more from the steer­
ing wheel, check with your authorized Audi
dealer to see if adaptive equ ipment is avail­
able .
-If the steering wheel is aligned with your
face, the supp lemental driver's airbag can­
not prov ide as m uch protection in an acci­
dent. A lways make s ure that the steering
wheel is aligned w ith your che st.
-Always hold the steer ing whee l with your
hands a t the 9 o' clock and 3 o'clock pos i­
t ions to reduce the ris k of person al injury if
the driver 's airbag deploys.
-Never hold the s teer ing whee l at the 1 2
o'clock pos it io n or w ith your ha nds inside
the steering wheel rim or on the steer ing
wheel hub . Holdi ng the steering whee l the
wrong way can cause serious injuries to the hands, arms and head i f the driver's airbag
deploys.

Trailer towing
Trailer load distribution
Be sure the load in the trailer is held securely in
p la ce to prevent it from shifting forward, back­
ward or sideways .
Never allow a passenger to ride in a trailer~&.
in Driving instructions on page 91.
Engine cooling system
Towing a trailer makes the engine work harder . It
is important that the coo ling system's perform­
ance is up to t he additional load. Make sure that
the cooling system has eno ugh fluid .
Tire pressure
When tow ing a tra iler, inflate the tires of your
veh icle to the tire pressure listed under "Full
load " on the label
~ page 293. Inflate trailer
tires to trailer and tir e ma nufactu rers' specifica­
tions.
Lights
Check to make sure both vehicle and trailer lights
are working properly .
Safety chains
Be sure trailer safety chains are proper ly connect­
ed from the trailer to the hitch on the vehicle.
Leave enough slack in the chains to permit turn­
ing corners . When you install safety cha ins, make
sure they w ill 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 .
Adjusting the Audi drive select
Make sure the vehicle is on a level surface before
hitching up the trailer and before adjust ing the
tongue we ight. The vehicle must be in
auto or
comfort driving mode and not ra ised
~ page 111, ~0 .
Make sure that the vehicle is lowered. In Info­
tainment, select:
ICARI function butto n> Lower
control button.
90
If you must drive under poor road conditions, you
can raise the ve hicle
after coupling the trailer or
after adjust ing the tongue we ight ~ page 113.
@ Note
-Changes in temperature or load can aff ect
the height of the vehicle .
-Always select auto or comfort mode. Other­
wise, the tong ue load specified for your ve­
hicle will no longer be applicab le .
Driving instructions
Driving with a trailer always requires extra care
and consideration.
Weight distribution
Towing a loaded trailer with an empty car results
in a hig hly unstable distribution of we ight. If th is
cannot be avoided, drive at very low speeds only
to avoid t he risk of losing steering contro l.
A "balanced" rig is eas ier to operate and control.
This means that the tow vehicle s hould be loaded
to
the extent possible and permissib le, w hil e
keeping the trailer as light as possible under the
circumstances. Whenever possible, transfer
some cargo to the luggage compartment of the
tow veh icle while observing tongue load require­
ments and vehicle loading considerations.
Speed
The higher the speed, the more difficu lt 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 cond it ions are unfavorable - particularly whe n
go ing down hill.
Reduce vehicle speed
immediately if the trailer
shows the slightest sign of sway ing.
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.
A lways 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.
ll-

Intellig ent T echn olo gy
- New brake pads do not achieve their full
braking effect during the first 250 mi
(400 km). They must be "broken in" first.
However, you can compensate for the
sl ightly reduced brak ing force by pressing
firmly on the brake pedal. Avoid heavy brak­
i ng dur ing t he break- in per iod.
- Certa in weather and operat ing cond it ions
such as dr iv ing through water, driving in
heavy ra in or driving after washing your ve ­
hicle can impair the effectiveness of the
brakes . In the winter, ice may build up on
the brake pads, rotors and drums . Check
these components by braking carefu lly. Ap­
plying the brakes carefully severa l times
dr ies the brakes and removes ice bu ild-up.
- The effic iency of the brakes can also be im­
paired by driving for long stretches on roads
covered w ith salt w ithout using the brakes.
You can remove salt deposits from the brake rotors and pads by carefully applying
the b rakes severa l t imes .
- If the front spo iler is damaged or you install
another spoiler, make sure the front wheel
bra kes are vent ilated properly. Otherwise,
the brake system could ove rheat, w hich re ­
duces the ir effectiveness.
- Failure of a b rake circuit impa irs b raking
perfo rmance, which inc reases brak ing dis ­
tance . Avoid driving the vehicle and have it
towed it to the nearest authorized Audi
dealer or authorized Audi Service Facility .
- If the brake booster is not working, you will
have to press m uch 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 distance and
causes wear.
- Before driving downhill a long distance on a
steep hill, decrease your speed and select a l ower gear. This makes use of the engine
braking effect and relieves the brakes. If
130
you need to brake add itiona lly, brake in in­
terva ls and not continuous ly .
(D Tips
- If the bra ke boos ter is not wor king, you
must press the brake peda l with much more
force than normal.
- If you retrof it your vehicle with a front spoi l­
er, wheel covers or simi lar items, make sure
that the air flow to the front wheels is not interrupted. Otherwise the brake system
can become too hot.

Checking and Filling
Checking and Filling
Gasoline
Fuel supply
Applies to: vehicles with gasoline engine
Using the right fuel helps keep the environment
clean and prevents engine damage .
Fuel recommendation
The fuel recommended for your vehicle is unlead­
ed premium
grade gasoline . Audi recommends
using TOP TIER Detergent Gasoline with a mini­
mum octane rating of91 AKI (95 RON). For more
information on TOP TIER Detergent Gasoline,
please go to the offic ial website
(www.toptiergas .com).
The recommended gasoline octane rat ing for
your engine can also be found on a label located
on the ins ide of the fuel filler flap. This rating
may be specified as AK I or RON .
Your veh icle may also be operated using unlead­
ed regular gasoline with a minimum octane rat ­
ing of 87 AKl/91 RON . However, using 87 AKI/91
RON octane fuel w ill slightly reduce engine per­
formance.
Use unleaded gasoline only. Unleaded gasoline
is available throughout the USA, Canada, and in
most European countries. We recommend that
you do not take your vehicle to areas or count ries
where un leaded gasoline may not be available.
For more information on refueling your vehicle,
see
~ page 269 .
Octane rating
Octane rating indicates a gasoline's ability to re­
sist engine damaging "knock" caused by prema­
ture ignit ion and detonation . T herefore, buy ing
the correct grade of gasoline is very important to
he lp prevent possible engine damage and a loss
of eng ine pe rformance.
Gasoline most commonly used in the United
States and Canada has the following octane rat­
ings that can usually be found on the filler pump:
- Premium Grade: 91 - 96 AKI
268
-Regular Grade: 87 -90 AK I
Explanation of the abbreviations :
AKI =
Anti Knock Index = (R +M)/2 = (RON +MON)/
2
RON = Research Octane Number
MON= Motor Octane Number.
@ Note
- Do not us e any fuel with octane ratings low­
er than 87 AKI or 91 RON otherwise expen­
sive engine damage will occur .
- Do
not us e leaded gasoline. The use of lead­
ed gasoline will severely damage your vehi ­
cle's catalytic converter and its ability to
contro l exhaust emissions .
Blended gasoline
Applies to: vehicles with gasoline engine
Use of gasoline containing alcohol or MTBE
(methyl tertiary butyl ether)
You may use unleaded gasoline blended with al­
cohol or MTBE (commonly referred to as oxygen ­
ates) if the blended mixture meets the follow ing
criteria :
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
-Anti -knock index must be 87 AKI or higher.
- Blend must contain no more than 3% metha-
nol.
- Blend must contain more than 2% co-solvents.
Blend of gasoline and ethanol (grain alcohol or
ethyl alcohol)
- Anti-knock index must be 87 AKI or h igher .
- Blend must not conta in more than 15% etha-
nol.
Blend of gasoline and MTBE
-Anti -knock index must be 87 AK I or h igher.
- Blend must not contain more th an 15% MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform es­
pecially well for winter or summer dr iv ing . Dur-
i ng seasonal change-over, we suggest that you
IJIJ,

u. co .... N
" N .... 0 0 :c ' fill up at busy gas stations where the seasona l
adjustment is more like ly to be made in time .
@ Note
-Methanol f uels whi ch do not meet these re ­
quirements may ca use corrosion and dam­
age to plastic and rubber components in the
fuel system .
- Do not use fuels that fai l to meet the speci ­
fied criteria in this c hapter.
- If you are unable to determine whether or not a particular fue l blend meets the speci ­
fications, ask your service station or its fuel
supplier.
- Do not use fuel for which the contents can­
not be identif ied.
- Fuel system damage and performance prob ­
l ems resulting from the use of fue ls differ­
ent from those specif ied are not the respon­
s ibility of Audi and are not covered under
the New Veh icle or the Emiss ion Control
System Warrant ies .
- If you experience a loss of fue l economy or
driveability and performance problems due
to the use of one of these fuel blends, we
r ecommend that you switch to unblended
fuel.
Gasoline additives
Applies to: vehicles with gasoline engine
A majo r concern among many auto manufactur ­
ers is carbon deposit build-up caused by the type
of gasoline you use.
A lthough gasoline grades d iffer from one manu­
facturer to another, they have cer tain things in
common . A ll gasoline grades contain substances
that can cause deposits to collect on vita l engine
parts, such as fue l injectors and intake valves . A l­
though most gasoline brands include additives to keep engine and fuel systems clean, they are not
equally effective.
Audi recommends using TOP TIER Detergent Gas­
oline. For more informat ion on TOP TIER Deter­
gent Gasoline, please go to the official website (www .toptiergas .com) .
Check ing and F illing
A fter an extended period of using inadequate
fuels, carbon deposit bui ld-ups can rob your en ­
gine of peak performance.
@ Note
Damage or ma lf u nction due to poor fue l qual ­
ity is not covered by the A udi New Vehicle
L imited Warranty .
