The Malfunction Indicator Lamp (MIL) • in the instrument cluster
::::>
page 14, fig. 7 is part of the On-Board Diagnostic (OBD II) system.
Th e warn ing/indicator light illuminates when the ignition is switched
on and goes out after the engine starts and the idle has stabilized.
Thi s ind icates that the MIL is working properly.
If
the light does not go out after the engine is started, or illuminates
while you are driving , a ma lfunction may exist in the engine system.
If the light illuminates, the catalytic converter could be damaged.
Continue driving
with reduced power (avoiding sustained high
speeds and/or rapid accelerat ions) and have the condition corrected .
Contact your authorized Audi dealer .
If the light i lluminates, the electronic speed limiter may also be
malfunctioning. For more information::::>
page 30, "Electronic speed
limiter".
An improperly closed fuel filler cap may also cause the MIL light to
illuminate (only vehicles with gasoline engine)::::>

Electronic speed limiter
Your vehicle may be factory equ ipped w ith tires that are rated for a
maximum speed of 130 mph (210 km/h). This is less than the
maximum speed of your veh icle. To reduce the risk of sudden tire
failure and loss of control if the vehicle is operated at excessive
speeds, your vehicle also has an electronic speed limiter . The elec­
tronic speed limiter prevents your vehicle from going faster than the
tire speed rating . For more information ::::>

Speed warning system
Overview
The speed warning system helps you t o keep your driving
speed bel ow a set speed limit.
Th e speed wa rning system warns the d river if he exceeds a p reviously
sto red maximum sp eed. A wa rning tone will sound as soon as the
vehicle speed exceeds the set speed by about 3 mph (3 km/h). At the
sa me time, a warning symbol appears in t he d isp lay.
T he speed warning system has
two warning thresholds that function
independen tly of each o ther and tha t have somewha t di ffe rent
purposes:
Speed warning 1
You can use speed war ning 1 to set the max imum speed w hile you are
driving. This setting w ill remain in effect unt il you turn off the igni ­
tion, assum ing that you have not changed or reset the setting .
Th e spee d warning symbo l
e (USA models)/ 8 (Canada mode ls) in
the warning 1 display appears when you exceed the maxim um speed.
It goes out when the speed falls be low the stored maximum speed.
T he spee d warning symbo l w ill also go out i f the spee d
exceeds the
stored maximum speed by more than about 25 mph (40 km/h) for at
least 10 seconds. The stored maximum s peed is de leted .

Adaptive Air Suspension
Air suspension and damping
Applies to veh icles : w ith Adap tive Air Suspens ion
Description
Air suspension and damping can be adjus ted separately.
Adaptive Air Suspens ion is an e lectron ically controlled springing and
damping sys tem. This chass is sys tem makes it eas ie r on the d river by
adapting to the particular si tuation through imperceptible control
processes.
T he
Adaptive Air Su spen sion component regu lates ground clea rance
depending on vehicle speed and driver input . It funct ions indepen ­
dently from the load cond it io n. Ac ce le rating to a speed above a
predetermined limit will make the vehicle lower itse lf. On the other
hand, dr iv ing more slowly res ults in the vehicle r aising again at
specific speeds.
T he
damping component provides individua l control of the damping
forces . For example , w ith damping characte rist ics set to p rovide
greater comfort, damping is set somewhat harder for a brief period
only as req uir ed, for example, whe n going a ro und a curve or when
brak ing.
Sett ings
Adaptive Air Suspension provides the driver with the opportun ity to
set the chass is characte rist ics also to their individual p refe rence.
With the driving modes
Comfort, Automatic and Dynamic the dr iver
has three chass is sett ings available, ranging from comfort to spo rty.
The
Offroad mode ca n be selected for dr iv ing on poor quality
s tr etc hes of road. In addition,
Li~ provides a fif th mode, w hich can be
selected when exceptiona lly high g round clearance is needed
==> page 179, "C hass is controls ".
T he modes are set in MMI
==> page 180 .
& WARNING
The height of th e parked vehicle can change du e to temperature
fluctuations or changes in load.
0 Note
• Whenever you park yo ur vehicle, always make sure there is
ade qua te clearance above and below t he ve hicle. The height of the
parked vehicle can change as the result of temperature fluctuations,
c hanges in loa d condition and changes in the dr iv ing mode (ground
cleara nce).
• If the veh icle is be ing transported (e .g . by tow truck, tra in , sh ip,
etc.), mount the tie-down cha ins/cables over the running su rface
(circumference) of the tires. Never se cure the vehi cle by the ax le, the
suspension struts or the front or rear tow line eye. For technical
reaso ns, the p ressure in the suspension st ru ts may change dur ing the
t ransport, whic h could result in the vehicle no longer being secured
pro perly.
• If you are goi ng to tow a trailer w ith a tra iler h itch that was
not
ins talled accor ding to f actory s pecifi cations, you mus t activa te t he
t rai ler operation mode manually:::::,
page 182.
[{] Tips
• Before you ca n raise your vehicle using the vehicle jack (for
example, when c hangi ng a flat tire) or a vehicle lift, you must activate
t he jac kin g mode :::::,
page 182.
• On some mode ls, the vehicle can reach its maximum speed on ly in
t he
Automatic and Dynamic modes .•

& WARNING (conti nu ed )
• Pleas e obse rve information on s afe driving => page 190.
& WARNING
To help prevent poi sonous exhau st ga s from being drawn into the
vehicle, always keep the rear lid closed while driving.
• Never transport object s larger than tho se fitting completely
into the luggage area because the rear lid cannot be fully closed.
• If you ab solutely must drive with the rear lid open, observe the
following notes to reduce the ris k of po isoning:
- Close all windows,
- Close the Pano ramic sliding sunroof*,
- Open all air outlets in the instrument panel,
- Swit ch off the air recirculation,
- Set the fresh air fan to the h ighest speed.
& WARNING
Alway s make sure that the doors, all windows, the Panorami c
sliding sunroof* and the rear lid are secur ely closed and locked to
reduce the risk of injury when the vehicle is not being used.
• After closing the rear lid, always make sure that it is properly
clo sed and locked .
• Never leave your vehicle unattended especially with the rear lid
left open . A child could crawl into th e vehicle through the luggage
compartment and close the rear lid becoming trapped and unable
to get out . Being trapped in a vehicle can lead to serious personal
injury.
• Never let children play in or around the vehicle.
• Never let passengers ride in the luggage compartment. Vehicle
occupants must alway s be properly restrained in one of the
vehicle 's seating positions.
W Tips
• Air circulation helps to reduce window fogging. Sta le air escapes
to the outside th rough vents in the trim panel. Be sure to keep these
slo ts free and open.
• Th e tire pressure m ust correspond to the load . The tire pressure is
shown o n th e t ire pressu re label. The tire pressure label is located o n
the driver's side 8-pillar . The tire p ress ure label lists the recom­
me nded co ld tire inflation pressures fo r th e ve hicle at its max imum
capacity weight and the tires that were on your vehicle at t he time it
was manufactured. For recommended t ire pressu re s for normal loa d
conditions, p lease see chapter=>
page 322. •
Tie-downs
The lug gage c omp artm ent is equ ipped with fo ur tie­
do wns to secur e luggag e and oth er items .
Use the t ie-downs to sec ure yo ur cargo properly => page 197,
"Load ing the l uggage comp artmen t".
In a co llision , the laws of physics mean that even smaller items that
are loose in the vehicle will become heavy m issi les t hat can ca use
ser ious injury. Items in the vehicle possess energy which va ry with
veh icle speed and the weight of the item . Vehicle speed is the most
sign ifi cant factor .
For example, in a frontal coll is ion at a speed of 30 mp h (48 km/h),
the forces a cting on a 1 0-lb (4.5 kg) o bje ct are about 20 times the
normal weight of the item. This means that the weight of the item
wou ld sudden ly be abo ut 200 l bs. (9 0 kg). You can imagine the inju ­
r ies that a 200 lbs. (90 kg) item flying freely through the passenger
compar tment cou ld cause in a collision like this .

& WA RNING (conti nu ed )
• Plea se be aware th at in ESP offroad mode , particularly on a
s mooth and slippery road, the wheels may have an incr eased
tendency to spin and the vehicle may break awa y -danger of skid ­
ding!
• Stabilit y is limited in the ESP offroad mode. •
Electronic differential lock (EDL)
The electronic differential lock monitors the rotational
speed of the drive wheels.
General notes
The electronic differe ntia l lock (EDL) helps the ca r to sta rt moving,
acce lerate and climb a gradient on surfaces provi ding poor or almost
no grip. W ithout ED L, th is would be d iff ic ul t, if not impossible .
How the system works
The EDL operates automatically . It mo nitors the rotational speed of
w heels wi th the help of the ABS sensors ==>
page 260. If a not iceab le
slip is detected at the wheels (e .g . o n slippery g round on one side),
the spin ning whee ls are braked and power is transferred to the other
wheels. This is done up to a speed of about 60 mph ( 100 km/h) .
Noises from the brake system signa l that wheel spin is being
cont rolled.
Driv ing off
W hen d rivi ng off, always be sure to keep road conditions in mind as
you acce lerate. If one drive wheel spins because it is on a surface with
less grip, apply
plenty of th rottle until t he car starts to move .
Overheating of brakes
To prevent the disc b rake of the bra ked wheel from overhea ting if
subjected to excessive loads on this whee l, t he EDL cuts out tempo ­
ra rily. The vehicle rema ins operat iona l and behaves in the same way
as a veh icle without EDL. As soon as the brake has coo
led down, EDL sw itches on again auto­
m atically.
& WARNING
• When accelerating on slippery surfaces, such as on ice or snow,
always be careful when depressing the accele rator pedal. Even
with the EDL working , the drive wheels c an spin and reduce your
ability to control your car . Risk of crash!
• The increased safety afforded by EDL does not mean that you
can take safety risks . Always adapt your d riv ing style to the road
c ondition s and traffic situation.
[ i ] Tips
If a fa ult occurs in the A BS, the ED L is also no t fu nct io ni ng. This is
ind icated by the ABS warn ing light==>
page 19. •
Anti-Slip Regulation System (ASR)
The Anti- S lip Re gula tion System preven ts the drive n
w heels from spin ning wh en the car is acc ele rating .
General notes
The Anti-S lip Reg ulation Sys tem (ASR) is in tegr ated in the ele ctroni c
stabilization program (ESP) . When the ve hicle starts up and acceler­
a tes, the whee ls are p reven ted from sp inning by adjust ing t he engine
power to match the amoun t of grip ava ilable from the road surface.
How the system works
ASR performs automatica lly, i.e. witho ut the driver 's intervent ion.
With the aid o f th e ABS sensors ==>
page 260, ASR moni to rs the speed
of the driven wheels. If the whee ls start to spin, engine torque is
reduced automatically unt il the tires find enough gri p to lock onto
the road s urface. The system is active ac ross the en tire speed range .
'1>

_________________________________________ I_ n_ t_ e_ ll_,igent technology ,__E~-
The ASR works in conjunction with the ABS. If a malfunction should
occur in the ABS, the ASR w ill also be out of action.
& WARNING
The increased safety afforded by ASR does not mean that you can
take safety risks. Always adapt your driving style to the road
conditions and traffic situation.
[ i] Tips
To ensure that the ASR works properly, all four whee ls must be fitted
with ident ical tires. Any differences in rolling radius of the tires can
cause the system to reduce engine power when th is is not desired.

Braking
General information
What affects braking efficiency?
Operating conditions and driving habits
The brakes on today's automobiles are still subject to wear,
depending large ly on operating conditions and driving habits=>& .
On vehicles that are either driven mostly in stop -and -go city traffic or
are driven hard, the brake pads should be checked by your authorized
Audi dealer more often than specified in the
Warranty & Mainte­
nance booklet.
Failure to have your brake pads inspected can result
in reduced brake pe rformance .
On steep slopes, you should use the brak ing effect of the engine . This
way, you prevent unnecessary wear on the brake system. If you must
use your brakes, do not hold the brakes down continuously. Pump the
brakes at intervals.
Noises may occur when braking depending on the speed , braking
force and outside conditions such as temperature and humidity.
Safety first
Moisture or road salt
If you are driving faster than 31 mph (SO km/h) and the windshield
wipers are on, the brake pads wi ll briefly touch the brake discs in
regular interva ls so as to improve reaction time when braking on wet
surfaces . You, the driver, will not not ice anything.
Under certain cond itions, for example, when driving through wa ter or
very heavy rain, or even after washing yo ur vehicle , the braking effect
can be reduced due to moisture (or in free zing conditions ice) on the
brake pads. A few careful brake applications should dry off the brake
pads or remove any ice coatings .
The effect iveness of the brakes can be reduced when the vehicle is
dr iven on a sa lt-covered road and the brakes are not used. Here too,
you should clean off accumu lated salt coating from brake discs and
pads with a few careful applications of the brake=> & -
Corrosion
There may be a tendency for dirt to build up o n the brake pads and
corrosion to form on the dis cs if the car is no t driven regularly or only
for short trips with little use of the brakes.
If the brakes are not used frequently, or if corrosion has formed on
the discs, it is advisable to clean off the pads and discs by braking
firmly a few times from a moderately high speed=> &.
Faults in the brake system
If you should notice a sudden increase in brake pedal travel, then one
o f the two brake circuits may have failed==>& .
Low brake fluid level
Malfunctions can occur in the brake system if the brake fluid level is
too low. The brake fluid level is monitored e lectron ically .
Brake lining wear status
Brake lining wear may be checked by visual inspection of the condi­
tion of the brake pads through the openings in the wheel. If neces­
sary, the wheel may be removed for this inspection =>
page 343,
"Changing a wheel". ._.

Note
If t he re is an elect ro n ic malfunc tion, servotroni c will still funct io n
like a conventional power steering system, provid ing a constant
steer ing suppo rt force tha t is no longer proportiona te to the vehi cle
speed. This is most noticeable when t urning the steer ing wheel at low
speeds (for ex ample when p arki ng), -m ore effo rt will be req uire d
than usua l.
• Be aw are of the d iffe ren t than usual steeri ng respo nse and adjust
your steering force accord ingly.
• Have t he pr oblem chec ked and set r igh t by a n Audi dea ler as soo n
as possib le .
[I) Tips
• When the engine is runni ng, neve r hold t he steering wheel turned
a ll the way to the r ig ht o r to t he left fo r longe r th an 1 5 seco nd s. The
powe r steering pump will over heat the hydraulic fluid if yo u keep
holding t he s teering w heel turne d all the w ay. This is likely to damage
the power steer ing system.
• If the powe r stee ring sys tem s ho uld fail entire ly, or if the engine
is not running (for examp le, while be ing towed), you will still be able
t o steer the vehicle. Howeve r,
considerably more effo rt will be
required to do so.
• If the powe r stee ring sys tem s ho uld have a leak, or is not func ­
tioning properly, contact your author ized Audi dealer immediately.
• Th e power s teeri ng system re quir es a specially fo rm ulated
hydraulic fluid. The power stee ring reservoir is the one located
f ar the st to the rea r on t he left side of the eng ine compa rtment
=> page 302. The correct fluid level in the reservo ir is important for
pr op er f unctio ning o f the power steer ing.•
