Observe the safety precautions ~ A in Working
in the engine comportment on page 330.
Checking the engine coolant level
.,. Park the vehicle on a level surface .
.,. Switch the ignit io n off.
.,. Read the coolant level on the coolant expansion
tank
¢ fig. 278 .
.,. The coolant leve l must be between the MIN and
MAX markings when the engine in cold. When
the engine is warm it can be slightly above the MAX marking .
Adding coolant
.,. Let the engine cool down.

.. Place a cloth over the coolant expansion tank
cap .
.. Push the release button ¢ fig. 2 78 and careful­
ly unscrew the cap to the left until you feel re­
sistance¢ &_ .
.. Push the release button again and remove the
cap completely .
.. Make sure that the fluid level remains stable .
Add more coolant if necessary .
.,. Turn the cap to the right to secure it until yo u
feel resistance a second time.
Coolant loss usually indicates there is a leak . Im­
mediately drive your vehicle to an authorized
Audi dealer or authorized Aud i Serv ice Facility
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 additive 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.
CD Note
Do not add coolant if the expansion tank is
empty. There may be air i n 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 dea ler or author­
ized Aud i Service Facility for assistance.

rectly, only use brake fluids that comp ly
with VW standard 501 14 or FMVSS-116 DOT 4.

Consumer Info rmation
today's a utomo biles, have steadily reduced the
scope of maintenance and repairs which can be
carried out by veh icle owners.
Also , sa fet y and
en vironmental
concerns place very strict limits
on the nature of repairs and adjustmen ts to en­

perform .
Maintenance, adjustments and repairs usually re­
qu ire special tools, testing devices and other
equ ipment available to specially trained work ­
shop personnel in order to assure proper per­
forma nce, re liability and safety of the veh icle and
its many systems .
Improper maintenance, adjustments and repairs
can impair the operation and reliab ility of your
ve hicle and eve n void your vehicle warranty .
Therefo re, proof of se rvicing in a ccordance w ith
the m aintenance sched ule may be a condition for
up ho ld ing a possible wa rranty claim made within
the wa rranty pe riod.
Above all , ope rational safety can be adversely af­
fected, cre ating unne cessa ry risks fo r you and
your passengers.
