wheel wi th the flat t ire. Installing the t ire
chai n befo re mounting the whee l and tire is
re comme nded.

Emergency situations
-The battery cell locking screws must be
tightened securely.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS
c:> page 203.
(D Note
Improper hook-up of jumper cables can ruin
the generator.
- A lways connect POSITIVE(+) to POSITIVE
(+), and NEGATIVE(-) to NEGATIVE(-)
ground post of the battery manager control
unit.
- Check that a ll screw plugs on the battery
cells are screwed in firmly. If not, tighten
plugs prior to connecting clamp on negative
battery terminal.
- Please note that the procedure for connect­
ing a jumper cable as described above ap­
plies specif ically to the case of your vehicle
being jump started. When you are giv ing a
jump start to another vehicle, do
not con­

0 ::..:: co ..... ..... today's automobiles, have steadily reduced the
scope of maintenance and repairs which can be
carried out by vehicle owners.
Also, safety and
environmental
concerns place very strict limits
on the nature of repairs and adjustments to en­
gine and transmission parts which an owner can perform .
Maintenance, adjustments and repairs usually re­
quire special tools, testing devices and other
equipment available to specially trained work ­
shop personnel in order to assure proper per­
formance, reliability and safety of the vehicle and its many systems.
Improper maintenance, adjustments and repairs
can impair the operation and reliability of your
vehicle and even void your vehicle warranty .
Therefore, proof of servicing in accordance with
the maintenance schedule may be a condition for upholding a possible warranty claim made within
the warranty period.
Above all , operational safety can be adversely af­
fected, creating unnecessary risks for you and
your passengers.
If in doubt about any servicing, have it done by
your authorized Audi dealer or any properly equipped and qualified workshop. We strongly urge you to give your authorized Audi dealer the
opportunity to perform all scheduled mainte­ nance and necessary repairs. Your dealer has the
facilities, original parts and trained specialists to keep your vehicle running properly .
Performing limited maintenance yourself
The following pages describe a limited number of
procedures which can be performed on your vehi­
cle with ordinary tools, should the need arise and
trained personnel be unavailable. Before per­
forming any of these procedures, always thor­
oughly read all of the applicab le text and careful­
ly follow the instructions given . Always rigorously
observe the
WARNINGS provided .
Before you check anything in the engine com­
partment, always read and heed all WARNINGS
c::> .&. and c::> .&. in Working in the engine compart­
ment on page 203 .
Consumer information
A WARNING
-Serious personal injury may occur as a result
of improperly performed maintenance, ad­
justments or repairs .
- Always be extremely careful when working
on the vehicle. Always follow commonly ac­
cepted safety practices and general com­
mon sense. Never risk personal injury.
- Do not attempt any of the maintenance,
checks or repairs described on the following pages if you are not fully familiar with these
or other procedures with respect to the ve­ hicle, or are uncertain how to proceed.
- Do not do any work without the proper tools
and equipment. Have the necessary work
done by your authorized Audi dealer or any
properly equipped and qualified workshop.
- The engine compartment of any motor vehi­
cle is a potentially hazardous area. Never
reach into the area around or touch the radi­
ator fan. It is temperature controlled and
can switch on suddenly - even when the en­
gine is off and the ignition key has been re­
moved. The radiator fan switches on auto­
matically when the coolant reaches a certain
temperature and will continue to run until
the coolant temperature drops.
- Always remove the ignition key before any­
one gets under the vehicle.
-Always support your vehicle with safety
stands if it is necessary to work underneath
the vehicle. The jack supplied with the vehi­
cle is not adequate for this purpose and
could collapse causing serious personal in­
jury.
- 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) or Neutral (manual transmis-
sion) and the park brake is firmly applied . ..,.
