Warning light in the instrument cluster display-1-
If the _L warning light in the i nstrument clus ter display flashes, this
can mean one of two things: either the coo lant
temperature is too
high, or the coolant
level is too low ~ page 29.
If the needle is well in the uppe r area of the gauge, the coo lant
temperature is too high.
Stop the vehicle, switch the engine off, and
allow it to cool.
If th e war ning light comes o n ag ain af ter driv ing a
short distance, contact an author ized Aud i dea ler or othe r qualified
wor ksh o p.

ment ", before opening the hood and checking the engine coolant
level.
• Never open the engine hood if you see or hear steam, or if you

could burn yourself . Let the engine cool off first so that you cannot
hear or see any steam or engine coolant .
0 Note
• Mounting add ition al lights o r accesso ries in fron t of the a ir inlets
reduces the cooling effect of the radiator . At high outside tempera­
tur es o r high engine load, the eng ine could ove rhe at.
• The front spo iler has been designed to properly d istribute the
c oo lin g air when the vehicle is moving. If the sp oi ler is d amaged, this
co uld reduce the cooling eff ect and the eng ine could then overheat .

& WARNING
• USA models: If the BRAKE warning light and the warning
light come on together, the rear wheels could lock up first under
hard braking. Rear wheel lock-up can cause lo ss of vehicle control
and an accident . Have your vehicle repaired immediately by your
authorized Audi dealer or a qualified work shop . Drive slowly and
avoid sudden, hard brake applications.
• Canada model s: If the brake warning light (CD) and the ABS
warning light :: come on together, the rear wheels could lock up
fir st under hard braking . R ear wheel lock -up can cause lo ss of
vehicle control and an accident. Have your veh icle repaired imme­
diately by your authorized Audi dealer or a qualified workshop.
Drive slowly and avoid sudden, hard brake applications .
• If the brake warning /indicator light doe s not go out after a few
seconds and the parking brake released, or lights up while you are
driving , the fluid level in the brake fluid reservoir is too low. If you
believe that it is safe to do so, proceed immediately at low speed
to the nearest authorized Audi dealer or qualified repair facility
and have the brake sy stem inspected .
• Always keep in mind that after several brake applications, you
will need greater pressure on the brake pedal to stop your vehicle .
Do not rely on strained brakes to re spond with maximum stopping
power in critical situations. You must allow for increased braking
distances. The extra distance used up by fading brakes could lead
to an accident . •
