Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of skid­
ding and loss of vehicle control. It works only
when the engine is running. ESC detects certain
d ifficu lt driving situations, including when the ve­
hicle is beginn ing to spin (yaw) out of control and
helps you to get the vehicle back under control by
selectively braking the whee ls, and/or reducing
engine power and prov iding steer ing ass istance
to help hold the vehicle on the driver's intended
course. The indicator light
Bl in the instrument
cluster blinks when ESC is taking action to help
you control the veh icle.
ESC has limitations.
It is important to remember
that ESC cannot overcome the laws of physics. It
will not always be able to help out under all con­
ditions you may come up against. For example, ESC may not always be able to help you master
situations where there is a sudden change in the
coefficient of frict ion of the road surface . Whe n
there is a section of dry road that is suddenly cov­
ered with water, slush or snow, ESC cannot per­
form the same way it wou ld on the dry surface. If
the vehicle hydroplanes (rides on a cushion of wa­
ter instead of the road surface), ESC will not be
ab le to he lp you steer the vehicle because contact
with the pavement has been interrupted and the
vehicle cannot be braked or steered . During fast
cornering, particularly on winding roads, ESC
cannot always deal as effectively with difficult
driving situations than at lower speeds. Whe n
tow ing a trailer, ESC is not able to help you regain
con trol as it wou ld if you were no t towing a trail­
er .
A lways adjust your speed and dr iving sty le to
road, traffic and weather conditions. ESC cannot
override the vehicle's physical limits, increase the
Smart Technology
available traction, or keep a vehicle on the road i f
road departure is a result of driver inattention.
Instead, ESC improves the possibility of keeping
the vehicle under control and on the road dur ing
extreme maneuvers by using the driver's steering
inputs to help keep the vehicle go ing in the in ­
tended direction. If you are traveling at a speed
that causes you to run off the road before ESC
can prov ide any assistance, you may not expe ri­
ence the benefits of ESC.
ESC is switched on all the time . In certain situa­
t ions when you need less traction, you can switch
off ASR by pressing the button
[ru ~ page 170,
fig. 152 or ~page 170, fig . 153. Be sure to
switch ASR on again when you no longer need
less traction.
T he following systems are integrated in the ESC:
Anti-lock braking system (ABS)
ABS prevents the wheels from locking up when braking. The vehicle can still be steered even dur­
i ng hard braki ng. Apply steady pressure to the
brake pedal. Do not pump the pedal. A pulsing in
the brake pedal indicates that the system is he lp­
ing you to brake the vehicle.
Brake assist system
The brake ass ist system can decrease braking dis­
tance . It increases braking power when the driver
presses the brake peda l quickly in emergency sit­
u at ions. You must press and hold the brake pedal
until t he situat ion is over. In vehicles with adap­
tive cruise control*, the brake assist system is
more sensitive if the distance detected to the ve­
hicle ahead is too sma ll.
Anti-slip regulation (ASR)
ASR red uces eng ine power when the drive wheels
begin to spin and adapts the force to the road
conditions. This makes it easier to start, acce le r­
ate and drive up hills.
Electronic differential lock (EDL)
T he EDL brakes whee ls that are spinning and
transfers the drive power to the other wheels.
T his function is available up to about 60 mph
(100 km/h).

Fuel and Refu elin g
CJ) Note
-Methanol fuels which do not meet these re ­
quirements may cause corros ion and dam­
age to plastic and rubber components in the
fuel system.
- Do not use fuels that fail to meet the speci­ fied criteria in this chapter .
- If you are 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 are not the respon­
s ibility of Audi and are not covered under
the New Vehicle or the Emission Contro l
System Warranties.
- If you experience a loss of fuel economy or
driveability and performance problems due
to the use of one of these fuel b lends, we
recommend that you sw itch to unb lended
fuel.
Gasoline additives
A major concern among many auto manufactur­
ers is carbon deposit build-up caused by the type
of gasoline you use .
A lthough 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 vita l engine
parts, such as fuel injectors and intake valves. Al­
though most gasoline brands include additives to
keep eng ine and fuel systems clean, they are not
equally effect ive .
Audi recommends using TOP TIER Detergent Gas­
oline . For more information on TOP TIER Deter ­
gent Gasoline, please go to the official webs ite
(www .toptiergas .com).
After an extended period of using inadequate
fuels, built-up carbon deposits can rob your en­
g ine of peak performance .

(D Note
Damage or malfunction due to poor fuel qual­
ity is not covered by the Audi New Vehicle
Limited Warranty.
Refueling
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel filler flap .
If the power lock ing system should fail, you can
still open the flap manually - for detailed instruc­
tions see
9 page 186.
You can find the fuel tank capacity of your vehicle
in 9 page234.
The label on the inside of the fuel filler flap tells
you the correct fuel for your vehicle . For more in­
format ion about fuel specifications, see
9 page 183.
Your vehicle fuel tank has an on-board refuelling
vapor recovery system. This feature helps to pre­
vent fuel vapors from escap ing from the tank and
po lluting the environment while you refuel your
vehicle. In order to fi ll the tank properly while
protecting the environment , p lease follow this
r efueling procedure carefully .
_& WARNING
Under normal operating conditions, never car­
ry additional fuel containers in your car . Gas
can isters and other containers used to trans­
port fuel can be dangerous . Such containers,
full or empty, may leak and could cause a fire in a co llision .
If you must transport fuel to
use for your lawn mower, snow blower, etc .,
be ve ry careful and always observe local and
state laws regarding the use, transportation
and storage of such fue l conta iners . Make cer­
tain the container meets industry standa rds
(ANSI/ASTM F8S2 - 86).
@ Note
Neve r drive your veh icle until the fuel tank is
complete ly empty. The ir regular supply of

Refuelling procedure
~ Insert the fuel nozzle from the gasol ine pump
into the fuel filler neck as far as it will go.
~ Select a medium refuelling rate so that the
nozzle switches off automat ica lly when the
tank is full.
Putting the fuel cap back on
~ After filling your tank, tw ist the f uel cap clock­
wise as far as it wi ll go.
~ Close the fuel filler flap.
Fuel and Refueling
To avoid fuel spilling or evaporating from the fuel
tank always close fue l cap proper ly and com­
pletely .
A WARNING
--
Improper refueling or handling of fuel can
cause fire, explosion and severe burns.
- Fuel is highly flammable and can cause se­
vere burns and other injuries.
- Failure to shut the engine off while refuel­
ing and/or to insert the pump noz zle fully
into the fue l filler neck could cause fuel to
spray out of filler neck or to overflow . Fuel
spray and overflowing fuel can cause a fire.
- Never use a cellular telephone while refuel­
ing. The electromagnetic radiation can
cause sparks that can ignite fuel vapors and
cause a fire .
- Never get back into your vehicle while refu­
eling. If in exceptional circumstances you
must get back in your vehicle whi le refuel­
ing, make certain that you close the door
and touch metal to discharge static electric­
ity before touching the filler nozzle again.
Static electricity can cause sparks that can ignite fue l vapors re leased during refueling.
- Never smoke or have an open f lame any­
where in or near your vehicle when refueling
or filling a portable fue l conta iner .
- For your safety, we strongly recommend
that you do not travel with a portable f uel
container in your vehicle. The container, full
or empty may leak and cou ld cause a fire,
especially in a crash.
- If, under exceptional circumstances, you
must transport a portable fuel container,
ple ase observe the following:
- Never fill a portable fuel container while it
is anywhere in or on the veh icle (for exam­
ple, in the luggage compartment, or on
the trunk). Static e lectricity can build up
while filling and can ignite fuel vapors
causing a f ire.
- Always place a portab le fue l container on
the ground before filling .
185

Fuel and Refueling
-Always keep the fi ller nozzle completely
inside the portable container before and
during filling.
- If filling a portable container made of
metal, the filler nozzle must always be in
contact with the container. This will help
prevent static electricity from discharging
and cause a fire .
-Never sp ill fuel inside the vehicle or lug­
gage compartment. Fuel vapors are highly
flammab le.
-Always observe local and state/provincia l
laws regarding the use, storage and trans­
portat ion of fuel containers.
- Make certain the fuel container meets in­
dustry standards (ANSI/ ASTM F852 -86) .
(D Note
If any fuel has spilled onto the car, it should
be removed immediately to prevent damage
to the paint .
@ For the sake of the environment
As soon as the correctly operated nozzle
switches off automatically for the first time,
the tank is full. Do not try to add more fuel
because fuel may spill out . In addition, the
expansion space in the fuel tank will be filled·
causing the fuel to overflow when it becomes
warm and pollute the environment.
(j) Tips
- Running your engine while refuelling may
cause vapors to escape or even cause fuel to
sp il l out of the tank . This wo uld then shut
off the fuel nozzle before the tank is full.
- Do not refuel your veh icle with the ignition
turned on. The fuel gauge may otherwise
not indicate the correct fuel level after refu­
elling.
- The fuel filler flap of your vehicle is not
l ocked when you lock the vehicle from the
inside .

Checking and Filling
"' Place a thick rag over th e coolant expansion
tank and
carefully turn the cap counter-clock­
wise
¢ ,& .
"'Read the engine coolant level inside the coolan t
expansion tank
¢ fig . 164, ¢page 189,
fig. 16 1.
With a cold engine , the coolant level
should be between the ' 'MIN" and "MAX " mark­
ings
¢ fig . 165 -arrows- . When the engine is
warm, the level may be slightly above the
"MAX" marking.
"'Add coolant mixed in the correct ratio, if neces­
sary ¢
page 192 . Coolant may be a maximum
of 1 mm above the MAX marking.
"' Twist the cap on again
tightly .
The location of the coolant expansion tank can be
seen in the engine compartment illustration
¢ page 189.
To obtain an accurate reading , the engine must
be switched off.
The expansion tank in your vehicle is equipped
with an electric coolant level sensor.
When the coolant level is too low, the warning
light in the Auto-Check System¢
page 17 will
blink until you add coolant and the level has been
restored to normal. Even though there is an elec­
tric coolant level sensor, we still recommend you
check the coolant level from time to time.
Coolant loss
Coolant loss may indicate a leak in the cooling
system. In the event of coolant loss, the cooling
system should be inspected immediately by your
authorized Audi dealer. It is not enough merely
to add coolant.
In a
sealed system, losses can occur only if the
boiling point of the coolant is exceeded as a re­
sult of overheating.
Adding coolant
Replacement engine coolant must conform to ex­
act specifications ¢
page 192, Coolant.
We recommend using only coolant additive Gl2+
+ , G l3
or in an emergency Gl2+ . Do not use a
different additive . In an emergency use plain wa­
ter until you can get the correct additive and can
194
restore the correct ratio. This should be done as
soon as possible.
If you have lost a considerable amount of cool­
ant, then you should add cold antifreeze and cold
water only when the engine is cold.
Always use
new engine coolant when refilling.
Do not fill coolant above the "MAX" mark. Excess
coolant will be forced out through the pressure
relief valve in the cap when the engine becomes
hot.
,&_ WARNING
- The cooling system is under pressure and
can get very hot. Reduce the risk of scalding
from hot coolant by following these steps.
- Turn off the engine and allow it to cool
down .
- Protect your face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag .
- Turn the cap slowly and very carefully in a
counter-clockwise direction while applying
light, downward pressure on the top of
the cap .
- To avoid being burned, do not spill anti ­
freeze or coolant on the exhaust system or
hot engine parts. Under certain condi­
tions, the ethylene glycol in engine cool­
ant can catch fire.
- Antifreeze is poisonous. Always store anti­
freeze in its original container and well out
of the reach of children.
- If you drain the coolant, it must be caught
and safely stored in a proper container
clearly marked "poison".
(D Note
- Do not add any type of radiator leak sealant
to your vehicle's engine coolant. Adding ra­
diator repair fluid may adversely affect the
function and performance of your cooling
system and could result in damage not cov­
ered by your New Vehicle Limited Warranty.
- Coolant pollutes the environment and could

Winter tires
W inter tires sign ificantly improve t he vehicle's
h andling when drivi ng in winter condit ions. Be­
cause of the ir construction (width, compound,
tread pattern), summer t ires p rov ide less t ract ion
on ice and snow.
.. Use w in ter t ires on all four wheels.
.. Only use winter tires that are approved for your
vehicle .
" Please note that the maximum permitted
speed may be lower w it h w inter tir es ~,&. .
You r authorized Audi dea le r or a uthorized re­
pair facility can in form you about the maximum
permitted speed fo r yo ur tires.
.. Check the tire pressure after insta lling wheels
~ page 206.
The effectiveness of winte r tires is reduced great ­
l y when the tread is worn dow n to a depth of
0 .157 inch (4 mm). The characteristics of w inter
tires also decrease greatly as the tire ages, re­
gardless of the remai ning tread .
A WARNING
-Never drive faster than the maximum per ­
mitted speed for your t ires. This could cause
the tires to heat up too much . This increases
the risk of an ac cident be cause it can cause
the tire to b urst.
- Always adapt you r driv ing to the road and
t raff ic conditions. Dr ive ca refully and re duce
yo ur speed on icy or slippery roads. Even
w inter tires can lose tract ion on black ice.
@ For the sake of the environment
Reinstall summer tires at the approp riate
t ime, because they prov ide be tter h and ling
when roads a re free of snow and ice. S ummer
tires ca use less road no ise, tire wea r and fuel
consumption.

{!) Tips
You can also use a ll season tires instead of
winter tires. P lease note that in some coun­
tries where w inter tires are required, only win­
ter tires w ith the
& symbol may be permit­
ted.
Snow chains
Snow chains improve traction in the snow .
.. On ly install snow chains on the front wheels .
T his applies a lso to vehicles with a ll whee l
drive .
.. Check and correct the seating of the snow
chains if necessary after driving a few feet . Fol ­
low the instructions from the manufactu rer .
.. Note the maximum permitted speed when dr iv­
ing wit h snow chains . Do not exceed 30 mph
(SO km/h).
Snow c ha ins not only improve the
driving in w in­
te r road cond itions , but also the
braking .
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons .
Check with an authorized Audi dea ler or author­
ized repa ir fac ility to see if you may use snow
chains.
Use
fine-mesh snow chains. They must not add
more than 0 .41 inch (10 .5 mm) in he ight, includ­
i ng the cha in lock.
You must remove the chains when driving on roads that are
free of snow . When roads are free
of snow, snow cha ins can impair handl ing and
damage the tires, and the chains wi ll quickly be
dest royed.
A WARNING
Using incor re ct snow chains o r insta lli ng snow
cha ins incorrect ly can result in loss of ve hicle
control, which increases the risk of an acci­
dent .
(D Note
Snow ch ains can damage the rims/wheel cov­
ers * if the chains come into direct contact
