• the engine compartment heats up because the vehicle is parked
in intense sunlight.
& WARNING
• To reduce the risk of personal injury never touch the radiator
fan.
• The auxiliary electric fan is temperature controlled and can
switch on suddenly even when the engine is not running .
• The auxiliary radiator fan switches on automatically when the
engine coolant reaches a certain temperature and will continue to
run until the coolant temperature drops. •
Brake fluid
Checking brake fluid level
The brake fluid level can be checked with a quick glance.
Fig. 143 Engine
compartment: brake
fluid reservoir
Before you check anything in the engine compartment,
always read and heed all WARNINGS=> & in "Working in
the engine compartment" on
page 217.
-Read the brake fluid level from the brake fluid reservoir
=> fig. 143. The brake fluid level must be between the
"MIN" and "MAX" markings.
The brake fluid reservoir is located behind the rear partition of the
engine compartment on the left side~ page 218.
The fluid level may drop slightly after some time due to the auto ­
matic 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/indicator light (U.S. models:
BRAKE, Canadian models:
(Cf))) will come on~ page 19 and~ page 33. Do not continue to
operate the vehicle. The complete brake system should be thor­
oughly checked by an authorized Audi dealer or other qualified
facility 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. •
Changing brake fluid
Have the brake fluid changed by an experienced techni­
cian.
Brake fluid absorbs moisture from the air. If the water content in the
brake fluid is too high, corrosion in the brake system may result
after a period 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 conforms to Federal Motor Vehicle Stan­
dard "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 autho­
rized
Audi dealer. Your dealer has the correct tools, the right brake
fluid and the know-how to do this for you.

& WARNING (continued)
• The engine compartment of any motor vehicle is a potentially
hazardous area. Never reach into the area around or touch the
radiator fan. It is temperature controlled and can switch on
suddenly -even when the engine is off and the ignition key has
been removed. The radiator fan switches on automatically when
the coolant reaches a certain temperature and will continue to run
until the coolant temperature drops .
• Always remove the ignition key before anyone gets under the
vehicle.
• Always support your vehicle with safety stands if it is neces­
sary to work underneath the vehicle. The jack supplied with the
vehicle is not adequate for this purpose and could collapse
causing serious personal injury.
• If you must work underneath the vehicle with the wheels on
the ground, always make sure the vehicle is on level ground, that
the wheels are always securely blocked and that the engine
cannot be started .
• Always make sure the transmission selector lever (automatic
transmission) is in "P" (Park position) (automatic transmission) or
Neutral (manual transmission) and the hand brake is firmly
applied.
<£> For the sake of the environment
• Changing the engine settings will adversely affect emission
levels. This is detrimental to the environment and increases fuel
consumption .
• Always observe environmental regulations when disposing of
old engine oil, used brake fluid, dirty engine coolant, spent batteries
or worn out tires.
• Undeployed airbag modules and pretensioners might be classi ­
fied as Perchlorate Material -special handling may apply, see
www.dtsc.ca.gov/hazardouswaste/perchlorate . When the vehicle or
parts of the restraint system including airbag modules safety belts
Controls and equip­ ment Safety first Vehicle operation with pretensioners are scrapped, all applicable laws and regula­
tions must be observed. Your authorized Audi dealer is familiar with
these requirements and we recommend that you have your dealer
perform this service for you. •
