_& WARNING
-Always observe the wa rni ngs in
¢ page 164, Working in the engine
compartment,
before opening the en­
gine hood and check ing the brake fluid.
- Driving with low brake fluid is a safety
hazard! Stop the car an d get professiona l
assistance.
- USA models: If both, the. warning
light and the
Ill warning light come on
at the same time, the rear wheels could
lock up first under hard brak ing . Lock-up
of the rear whee l brakes can cause loss of
vehicle control and an accident. Have
yo ur vehicle repaired immed iately by
you r autho rized Aud i dealer o r a quali­
fied workshop . D rive slowly and avo id
s u dden, hard brake application .
-Canada models: If both, the brake warn ­
ing light . and the ABS warning light
[iJ come on at the same t ime, the rear
wheels co uld lock up first unde r hard
braking . Lock -up of the rear wheel brakes
can cause loss o f vehicle control and an
acc ident. Have your vehicle repaired im­
med iate ly by your authorized Aud i 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
parking brake is released, or lights up
while you are dr iving, the f lu id leve l in
the brake flu id reservo ir is too low . If you
be lieve that it is safe to do so, proceed
immed iate ly at low speed to the nearest
author ized Audi dealer or qualified work­
shop and have the brake sys tem inspect­
ed .
- Always keep in mind that after severa l
brake applications, you will need greater
pressu re on the brake pedal to stop you r
vehicle . Do not rely on strained brakes to
respond with maximum stopping power
in critical s ituations. You must allow for
increased braking distances. The extra
distance used up by fading brakes could lead to an accident.

7 4 On the road
@ For the sake of the environment
To avoid unnecessary engine wear and to reduce exhaust emissions, do not let your
veh icle stand and warm up. Be ready to
drive off immediately after start ing your
veh icle. Maintain moderate speed until the
engine is comp letely warm. Remember,
the engine performs best at operating
temperature.
Stopping the engine
• Turn the ign ition key to position@
~ page 72, fig. 81.
&_ WARNING
-Never turn off the engine before the ve­
hicle has come to a complete stop. The
full function of the brake booster and the
power steering is not guaranteed. You
must use more force to turn or brake if
necessary. Because you cannot steer and
brake as you usually would, this could
lead to crashes and serious injuries.
- The radiator fan can continue to run for
up to 10 minutes even after you have
turned off the engine 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.
(D Note
Do not stop the engine immediate ly after
hard or extended driving. Keep the engine
running for approximately two minutes to
prevent excessive heat build-up.
Parking brake

The parking brake warning comes on only af­
ter you have driven for longer than 3 seconds
and faster than 3 mph (5 km/h).
The parking brake warning light . (USA)/ .
(CON) illuminates when the parking brake is
set and you switch on the ignition.
&_ WARNING
Always release the park ing brake com-
pletely. A partially engaged brake will
overheat the rear brakes, reduce their ef­
fectiveness and cause excessive wear. This
could lead to brake failure and an accident. .,..

the distance between your vehicle and
other vehicles.
- For safety reasons, the cruise control
should not be used in the city, in stop­
and-go traff ic, on twist ing roads and
when road conditions are poor (such as
ice, fog, gravel, heavy rain and hydro­
planing) -risk of accident .
- Turn off the cruise control temporarily
when entering turn lanes, highway exit
lanes or in construction zones.
- Please note that inadvertently "resting" your foot on the accelerator pedal causes
the cruise control not to brake. This is
because the cruise control is overridden
by the driver's acceleration.
({) Tips
The cruise control cannot maintain a con­
stant speed when driving downhill. The ve­
hicle will accelerate under its own weight. Downshift to a lower gear or use the
brakes to slow down .
Changing speed
.. Press leve r in the 0 or O direction
¢ page 77, fig. 85 to increase or decrease
your speed.
.. Release the lever to save that speed.
You can also press the 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 your saved speed by
5 mph (10 km/h) for longer than 5 minutes,
the cruise control will turn off temporarily .
The symbol will go out but the saved speed
will be retained .
Presetting your speed
You con preset your desired speed while the
vehicle is not moving .
.. Turn on the ignition . ..
Pull lever into position

Switching the ignition off erases the saved
speed.
_& WARNING
You should only return to the saved speed
if it is not too fast for the current traffic
conditions -risk of an accident!

84 Transmi ssion
because if the veh icle starts to roll
backward, you could cause an accident. If
the clutch should start to slip, you will
feel the vehicle "jerk" and the selector lever disp lay will start b linki ng .
- Before driv ing down a steep slope, re­
duce you r speed and shift into a lower
gear with "tiptronic" .
- Do not ride the brakes or app ly the brake
peda l too often or too lo ng . Constant
braking causes the b rakes to over heat
and substan tially red uces bra king pe r­
fo rm ance, in cr ease s bra king dis tance or
c a uses comp lete failure o f th e b rake sys­
tem.
Hill Descent Assist
Hill Descent Assist helps the driver when driv­
ing down inclines .
Hill Descent Ass ist is activated by pressing the
b rake w hile desce nding w hen the selecto r lev ­

maintain th e current vehicle spe ed whe n the
brak ing occu rs, as far as phys ica l and techni­
cal lim its a llow. It may be necessary to adjust
the speed using the brakes.
Hill Descent Assist switches off when the in­
cline levels out or when the gas pedal is press­
ed.

switched on all the time. In certain situations
when you need less traction, you can switch
off ESC by pressing the button
l!l . Be sure to
switch ESC on again when you no longer need
less traction.
Anti -toc k brak ing system (ABS)
ABS prevents the wheels from lock ing up
when braking . The vehicle can still be steered
even during hard brak ing . Apply steady pres­
sure to the brake pedal. Do not pump the ped­
al. A puls ing in the brake pedal ind icates that
the system is he lp ing you to brake the vehicle .
Brake assist sy stem
The brake assist system can decrease braking
d istance. It increases braking power when the
driver presse s the brake pedal quickly in emer­
gency si tuations. You must press and hold the
brake peda l until the situation is over .
Anti-slip regulation (ASR)
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to the road conditions . This makes it easier to
start, accelerate and drive up hills.
E lectronic differential lock (EDL )
The ED L brakes wheels that are spinning and
transfers the drive power to the other drive
wheel or whee ls if the vehicle is equipped with
all-wheel drive*. This function is available up
to about 60 mph (100 km/h) .
In extreme cases, EDL a utomatica lly switches
off to help keep the brake on the braked whee l
from overheating. EDL will switch on aga in au­
tomatically when conditions have returned to normal.
A WARNING
- ESC, ABS, ASR and ED L can not ove rcome
t h e laws of phy sics. This is espe cial ly im ­
por tant on slip pery or wet ro ads .
If th e
sys tems begin a ct in g to stab ilize your ve­
hicle, you shou ld imme diately change
yo ur speed to match the road and traffic
condit ions. Do not let the inc reased safe­
ty provided by these systems tempt you to take risks. Do
ing so w ill increase the
risk of a loss of veh icle control, co llision
and serious pe rsonal injuries .
- Always adapt your speed to road, traffic
and weather conditions. The risk of los­
ing control of t he vehicle increases when
driving too fast, espec ially through
curves and on slippe ry or wet roads, and
wh en dr iv ing too clos e to vehicl es u p
ahead. ESC, A BS, the brake ass ist sys­
tem, ED L and ASR cannot p reven t coll i­
si ons .
- Always acceler ate wi th sp ecial c are on
even, smoo th s urfaces such as those th at
are wet or covered with ice and snow .
The drive wheels can spin even with
these assistance systems that cannot al­ ways he lp to reduce the risk of loss of ve­
h icle co ntrol.
(D Tips
- ABS an d ASR only wo rk correct ly when
all four whee ls are equipped with identi­
cal tires . D ifferent tire si zes can lead to a
reduction in engine powe r.
- Yo u may hear noises when the systems
descr ibed are working.
- If the ind icator light Ii) or II (USA
mode ls)/ Ei] (Canada models) appears,
there may be a malfunction
