32 Opening and closing
Selective unlocking
The doors and rear lid lock when they close.
You can set in the MMI whether
only the driv­
er's door or the entire vehicle should lock
when closing
c::> page 36.
Automatic locking (Auto Lock)
The Auto Lock funct ion locks all doors and the
l uggage compartment lid once the speed has
exceeded approximately 9 mph (15 km/h) .
The car is un locked again once the ignition key
is removed. In addition, the vehicle can be un­
l ocked if the opening function in the power
locking system switch is used or one of the
door handles is pulled. The Auto Lock function
can be turned off or on in the MMI
c::>page36.
In the event of a crash with airbag dep loy ­
ment, the doors automatically unlock to allow
access to the vehicle.
Anti -theft alarm system*
If the anti-theft alarm system detects a vehi­
cle break-in, audio and visual warning signa ls
are triggered .
The anti-theft alarm system turns on auto­ mat ica lly when you lock the vehicle.
It deacti­
vates when un locking using the remote con­
trol key or by touching the sensor on the door
handle (convenience key).
To switch the alarm off, press them button on
the remote control key or convenience key or
switch the ignition on . The alarm also stops
automatically after a certain amount of time.
Turn signals
The turn signals flash twice when you unlock
the vehicle and once when yo u lock the vehi­
cle.
If they do not flash, one of the doors, the lug­
gage compartment lid or the hood is not
lock ed or the ignition is still sw itched on (the
latter applies to vehicles with a convenience
key) .
Unintentionally locking yourself out
The following situat ions prevent you from
locking your remote control key in the vehicle:
- The vehicle does not lock w ith the cent ral
lock ing switc h if the driver's door is open
c::>page3 5.
-On veh icles with a convenience key*, the lug­
gage compartment lid unlocks again after
clos ing if the most recent ly used key is in
the luggage compartment.
Do not lock your veh icle w ith the remote con­
trol key or convenience key* until all doors and
the luggage compartment lid are closed. This
helps to prevent from locking yourself out ac­
cidentally .
(D Tips
-Do not leave va luab les unattended in the
vehicle. A locked vehicle is not a safe!
- If the LED in the upper edge of the driv­
er's door turns on for about 30 seconds
after the vehicle is locked, there is a mal­
function in the power locking or the anti­
theft alarm system*. Have the problem
corrected by an authorized dealer or
qualif ied repair facility.
- The interior monitor ing of the anti-theft
alarm system* only operates correctly if
the windows and the sunroof* are closed.

Brake fluid
Checking brake fluid level
Fig . 153 Engine co mpa rtment: cove r on the b rake f lu id
reservo ir
B efore you check anything in the engi ne com­
partment,
alwa ys read and heed all WARN ·
INGS r:=:,page 210 .
~ Read the brak e fluid level from the brake
fluid reservo ir
r:=;, fig . 153, r:=:, page 212,
fig. 149 .
The brake f luid leve l mus t be be­
tween the "MIN" and "MAX " ma rkings.
The location of the brake flu id reservo ir can be
seen in the engi ne compa rtment illust ra ti on
¢ page 212 .
The fluid level may drop slightly after some
time due to the automatic adjustment of the b rake pads . Thi s is not cause for alarm.
If the brake fluid level falls
considerably be ­
low the "MIN" mark, the b rake wa rning/ind i­
cato r light . (U .S . models)/ . (Canadian
models) will come on
r:=;, page 18 . Do not con­
tinue to operate the vehicle. The comp lete
brake system should be thoroughly checked
by an authorized A udi dealer or other quali­
f ied fac ility and the ca use corrected . If the
br ake fluid level is too low, the brake warning/
indica tor light w ill illuminate. Contact an au·
thor ized Audi dealer
immediately .
Changing brake fluid
Have the brake fluid changed by an experi­
enced technician .
Brake fluid abso rbs moist ure from the air. If
the water content in the brake fluid is too
Che cking and Fillin g 219
high, co rrosion in the brake system may resu lt
after a period of time . The boiling point of the
brake f lu id will also decrease conside rably and
decrease braking performance.
T herefore, the brake fluid must be changed
eve ry two year s. Always use new brake f luid
which conforms to Federal Motor Veh icle
Standard "FMVSS 116 DOT 4".
The brake fluid reservoi r can be difficu lt to
reach, therefore, we recomm end that you
have the brake fluid changed by your author­
i z ed
Audi dealer . Your dealer has the correct
tools, the right brake flu id and the know-how
to do this for you .
A WARNING
-
-Brake flu id is poisonous. It must be stor-
ed only in the closed or iginal containe r
out of the rea ch of children!
- Brake failure can resu lt from o ld or inap­
p rop riate brake f lu id. Observe these pre­
cautions:
- Use only brake f luid that meets SAE
spec ificat ion
J 1703 and conforms to
Federa l Motor Ve hicle Standard 116.
Always check with your authorized Audi
dealer to make sure yo u are using the
cor rect bra ke fluid. The cor rect type of
brake f luid is also i nd icated on t he
brake f lui d rese rvoir.
- The bra ke flu id must be new. Heavy us e
of the brake s can cause a vapo r lock if
the b ra ke fluid is left i n the system too
l ong . This can se riously affect the effi ­
ciency of the brakes as we ll as your
safety . This co uld resu lt i n an accident .
(D Note
Brak e fluid will dam age the pa int of your
vehicle .
@ For the sake of the environment
Because of the p rob lem of proper disposal
o f bra ke fluid as well as the spec ial too ls
r equired and the necessary exper tise, we
recommend that yo u have the brake flu id
changed by yo ur authorized Audi dea ler.
