BRAKE/ This warning/indicator light illuminates when
the brake fluid level is too low or when there
is a malfunction in the ABS, or when the park ­
ing brake is set.
If the - (USA models)/ . (Canada
models) symbol flashes in the disp lay with the
parking brake released, there is a ma lfuncti on
in the brake system . In addition to the sym­
bol, one of two messages appears in the dis­
play:

immediately by your authorized Audi
dealer or a qualified workshop. Drive
slowly and avoid sudden, hard brake ap­ plication.
- Canada models: If both, the brake warn­
ing light . and the ABS warning light
Ii] come on at the same time, the rear
wheels could lock up first under hard braking. Lock-up of the rear wheel brakes
can cause loss of vehicle control and an
acc ident. Have your vehicle repaired im­
med iately by your authorized Audi dealer
or a qualified workshop. Drive slowly and avoid sudden, hard brake application
- If the brake warning/indicator light does not go out after a few seconds and the
park ing brake re leased, or lights up while
you are driving, the fluid level in the brake flu id reservo ir is too low. If you be­
lieve that it is safe to do so, proceed im­
med iately at low speed to the nearest
authorized Audi dealer or qualified work­
shop and have the bra ke system inspect­
ed.
- Always keep in m ind that afte r several
brake applicat ions, you will need g reater
pressure on the b rake peda l to stop your
vehicle. Do not re ly on strained brakes to
respond with maxim um stopping power
in critical situations . You must allow for
increased brak ing distances. The extra
distance used up by fad ing brakes could
lead to an acc ident.
~ / ! .!r Safety systems
The I (USA models)/ . (Canada mode ls) in­
d icator light monitors the safety systems e.g.
a irbags, pretensioners a nd illum inates for a
few seconds each time you switc h the ign ition
on.
If the
I (USA models)/ . (Canada models)
indicator light does not go out, or if it illumi­
nates w hile you are driv ing, or if it sta rts to
b lin k, then there is a ma lf u nction somewhere
in the system. If the light does not illuminate
when you switch on the ignition, this also
means there is a ma lfunction.

@ For the sake of the environment
To avoid unnecessary engine wear and to reduce exhaust emissions, do not let your
vehicle stand and warm up. Be ready to
drive off immediately after start ing your
veh icle. Mainta in moderate speed until the
engine is completely warm . Remember,
the engine performs best at operating
temperature .
Stopping the engine
.. Turn the ignition key to position@
¢page 89, fig. 102.
_& WARNING
-Never turn off the engine unti l the vehi­
cle has come to a complete stop.
- The brake booster and servotronic on ly
work when the engine is running . With
the ignition turned off, you have to apply
more force when steering or braking.
Since you cannot steer and stop normal­ ly, this can lead to accidents and serious
injuries.
- The rad iator fan can continue to run for
up to 10 minutes even after you have
tu rned off the eng ine and removed the
ignition key. The radiator fan can also
turn on again if the engine coolant heats
up because of intense sunlight or heat
build-up in the engine compartment.

Cruise control
Switching the system on
The cruise control system makes it possible to
drive at a constant speed starting at 20 mph (30 km/h) .
Fig. 105 Control lever wi th set button
Fi g. 106 Disp lay: Se lected speed
• Pull t he lever to posi tion (D ¢ fig . 105 to
switch the sys tem on.
• Drive at the speed you wish to set .
• Press b utton @ to set that speed .
The display
¢fig. 106 will show the set s peed .
The display may v ary depending on t he type o f
display in yo ur vehicle. The indicator
light
[ifj11 )~1~ (US mode l) I. (Canadian mode l)
will also light up in the instrument cluster.
A WARNING
- Always pay attention to traffic even when
the cruise control is switched on . You are
always responsible for your speed and
the distance between yo ur vehicle and
othe r vehicles .
- For safety reasons, the c ruise control
sho uld not be used in the city, in stop­
and -go traff ic, on twist ing roads an d
when ro ad conditions are poo r (such as ice,
fog, gravel, heavy rain and hydro­
plan ing) -risk of accident.
- Turn off the cruise contro l temporarily
when enter ing turn lanes, highway exit
lanes or in construction zones.
- Please note that inadvertently "resting"
your foot on the accelerator pedal causes
the cruise co ntrol not to brake. This is
because the cruise control is over ridden
by the dr ive r's acceleration.
(D Tips
- Veh icles with man ual transmiss ion: You
can attai n the set speed only if the cur­
rently engaged gear allows it and the en­
gine is not stressed . Sh ifting to a highe r
o r low er gea r promptly will a llow the en­
gine to r un smooth ly.
- The cr uise control can not mainta in a
constant speed when driv ing downhi ll.
T he vehi cle w il l accele rate under i ts own
we ight. Dow nshift to a lower ge ar or use
the brakes to slow down .
Changing speed
• Press lever in the 0 or 0 direct io n
¢ page 94, fig. 105 to increase or decrease
your speed.
• Release the lever to save that speed .
Change speed in increments of 1 mph (1 km/
h) by lightly pressing the lever. I f you keep the
lever pressed down, you will alter your speed
in S mph (10 km/h) increments.
You can also press t he accelerator pedal down
to increase your speed, e.g. if you want to
pass someone. The speed you saved earlier
will resume as soon as you release the acceler­
ator pedal.
If, however , you exceed yo ur saved speed by
5 mph (10 km/h) for longer than 5 minutes,
the cru ise control will turn off temporari ly.
T he symbo l will go out but the saved speed
will be reta ined .

Stopp ing on an incline
"' Always hold the vehicle with the footbrake
or parking b rake in order to p revent "roll ­
back"
¢ A . Do not try to prevent the vehi­
cle from rolling back by revving the engine
while it is in gear.
St artin g on a h ill
"' Apply the hand brake fi rm ly.
"' With the engine in gear, gradua lly acce ler-
ate and release the hand brake.
The engine can only be
s tar te d with the selec ­
tor lever in P o r N
c::> page 90 . At low ambient
temperatures
(14 °F /-10 °C), it is only possi­
b le to start the engine with the selector lever
in
P.
When parking on level ground , it is sufficient
to p lace the se lector lever in
P. On a steeply
sloping road, you should first apply the park­
ing brake firmly and then place the selector
lever in
P. This way, you do not overload the
pawl mechanism and it is eas ier to move the
selector lever out of P .
A WARNING
-Never leave your vehicle with the eng ine
running wh ile in gear. If you must leave
yo ur vehicle wi th the engine running, set
the parking bra ke and engage the pa rk
lock.
- When the engine is running and the
transmission is in gear (D, Sor
R) or in
"tiptronic" mode, it is essentia l that you
stop the vehicle with the footbrake .
When idling, the transmission of power
does not stop completely -the vehicle
"creeps".
- Do not accelerate when you change the selector lever position with the vehicle
stationary and the engine running - risk
of an accident!
- Never place the selector lever in the R or
N position while the vehicle is moving -
risk of an accident!
- If you have to bring your vehicle to a stop
wh ile on an incl ine, keep the foot brake
Tran sm iss ion 99
depressed all the way down so that the
veh icle does not sta rt to roll backward.
You should never ho ld the vehicle us ing
the clutch if you are going to be stopped
on an incl ine.
If you do, the clutch w ill
start to slip when it ove rheats caused by
the constan t overload. This is dangerous
bec ause if the vehicle starts to roll bac k­
ward, yo u co uld cause an acc iden t.
If the
clutch should start to slip, you wi ll feel
the vehicle "jerk" and the se lector lever
disp lay w ill start blink ing.
- Before driving down a steep slope , re­
duce your speed and shift into a lower
gear with "tiptronic".
- Do not ri de the brakes or apply the brake
pedal too often or too long. Constant
brak ing causes the brakes to overheat
and substantially reduces braking per­
formance, increases braking d istance or
causes complete fa ilu re of the brake sys­
t e m .
, Hill Descent Assist
App lies to vehicles : wi th S tronic t ra nsmi ssio n and H ill
D escent Ass ist
Hill Descent Assist helps the driver when driv ­
ing down inclines.
Hill Descent Assist is activated by pressing the
brake while descending when the se lector lev­
er is in
0 /5 . The S tronic transmission auto­
matically shifts down to a gear suitable for
the incline. H ill Descent Assist attempts to
maintai n the current veh icle speed w hen the
braking occu rs, as far as physical and techn i­
ca l lim its allow .
It may be necessa ry to adjust
the speed using the bra kes.
Hill Descent Assist sw itches off when the in­
cli ne leve ls out o r when the gas peda l is p ress ­
ed.
On vehicles with cruise control*
