Coolant
The engine coo ling system is filled with a mixture
of pur ified water and coolan t addit ive at the fa c
tory. This coo lant must not be not changed.

manually.
I f you must add coolant, use a m ixture of water
and coolant additive. M ixing the coolant additive
with d istilled wate r is recommended.
Coolant additive
The coolant additive is made of anti-freezing a nd
corros ion protection agents. Only use the fo llow
ing coo lant add it ives. These additives may be
m ixed w ith each other.

The amount of coo lant add itive that needs to be
mixed w it h water depends on the climate where
the vehicle will be operated. If the coolant addi
tive percentage is too low, the coolant can freeze
and damage the engine.

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 .
Fig. 250 Engine compa rtment: Cover o n the brake fluid
rese rvoir
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
