Anti-theft alarm system
If the anti-theft alarm system detects a vehicle
break-in, audio and visual warning signals are
triggered. The anti -theft alarm system is activat­
ed when the vehicle is locked as usual. It
switches off when the vehicle is unlocked.
If the alarm is triggered, it will shut off automat­
ically after a certain amount of time. Switch the
ignition on or press the @] button on the remote
control key to turn off the alarm .

and have the cooling system inspected. If the
cooling system is not leaking, a loss can come
from the coolant boiling through overheating and being pushed out of the cooling system.
A WARNING
- The cooling system is under pressure. Do
not open the coolant expansion tank cap
when the engine is hot. This increases the
risk of burns .
- The coolant add itive and the coolant can be
dangerous to your health. For this reason,
keep the coolant in the original container
and away from children. There is a risk of
poisoning.
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of injury.
(D Note
Do not add coolant if the expansion tank is
empty. There may be a ir in the cooling sys­
tem, which increases the risk of engine dam­
age . If this is the case, do not continue driv­
ing . See an authorized Audi dealer or author­
ized Audi Service Facility for assistance.
Brake fluid
Checking brake fluid level
The brake fluid level can be checked with a quick
glance .

Before you check anything in the eng ine compart ­
ment,
always read and heed all WARNINGS
Checking and Filling
c::> .&. in Working in the engine compartment on
page 304.
" Read the brake fluid level from the brake fluid
reservoir
c::> fig. 250, c::> page 306, fig. 247. The
brake fluid level must be between the "MIN"
and "MAX" markings.
The brake flu id reservoir is located at the rear
partition of the engine compartment on the left
side
~ page 306 .
The fluid level may drop slightly after some time
due to the automatic adjustment of the brake
pads . This is not cause for alarm.
If the brake fluid level falls considerably below
the "MIN" mark, the brake warning/indicato r
light (USA models:
11111 , Canada models : II>
will come on c::> page 29. Do not continue to oper­
ate the vehicle. The complete brake system
should be thoroughly checked by an authorized
Audi dealer or qualified workshop and the cause
corrected . If the brake fluid level is too low, the
brake warning/indicator light will illuminate .
Contact an authorized Audi dealer
immediately .
@ Tips
The brake fluid reservoir is located under­
neath the cover.
Changing brake fluid
Hove the broke fluid changed by on experienced
technician.
Brake fluid absorbs moisture from the air. If the
water content in the brake fluid is too high, cor­
rosion in the brake system may result after ape­
riod of time. The boiling point of the brake fluid
will also decrease considerably and decrease braking performance .
Therefore, the brake fluid must be changed
every
two years .
Always use new brake fluid which con­
forms to Federal Motor Vehicle Standard "FMVSS
116 DOT 4" .
The brake fluid reservoir can be difficult to reach,
therefore, we recommend that you have the brake fluid changed by your authorized
Audi
dealer.
Your dealer has the correct tools, the
