Emerg enc y s it uati ons
9. In the ve hicle that is being jump started,
switch the heater fan and rear window de ­
froster on to reduce any voltage peaks that
may occur when disconnecting the jumper
cables. The headlights must be switched off.
10. With the engines running, remove the cables
i n
reverse order of the way they were instal­
l ed. Make sure the cables do not get caught
in mov ing engine components.
11. Sw itch the heater fan and rear w indow de-
froster off.
12. C lose the battery cover .
The battery is vented to the outside so that gases
do not enter the passenger compartment. Make
sure that the connected positive termina l clamps
on the jump start cab le have sufficient contact
with metal.
A WARNING
Follow the warnings and instructions from
the jump start cab le manufacturer to reduce
the risk of ser ious injuries and vehicle dam­
age. If you are unsure about anything, call
roads ide ass istance.
- The jump start cables must be long enough
so that the veh icles do not touch.

- Route the jump start cables so they cannot
get caught in the moving parts in the engine
compartment.
- Always read and follow the warnings before check ing anything in the engine compart­
ment
~page 316.
(D Note
Connecting jump start cables incorrectly can
damage the alternator .
- Always connect the positive terminal(+) to
the positive term inal(+) and the negative
term inal(-) to the negat ive terminal(-) on
the body ground po int, but not the negative
terminal on the battery.
- Make su re the screw plugs on the battery
cells are installed securely. If not, tighten
the plugs before connecting the clamps to
the negat ive termina l on the b attery.
- Please note t hat the connecting p rocess de­
scribed below for the jump sta rt cab les is
in-
370 tended for when your vehicle is being jump
started. If you are jump starting another ve­
hicle, do not connect the negat ive cab le to
the negative term inal (-) on the dra ined
battery, but rather connect it to a large
metal component that is bolted secure ly to
the engine block, or to the engine block it­
self.
If the battery in the vehicle being jump
sta rted is not vented to the outside, there is
a risk of explosion due to hyd rogen gas.
- Make sure that the connected pos itive ter­
minal clamps have suff icient contact with
metal.
- Do not use the battery negative terminal fo r
jump starting or a ma lfunction co uld occ ur

distr ibut ion an d ba lance . This might hap­
pen, for exam ple, when heavy compo­
nents such as the engine b lock or trans­
miss io n are removed.
- When removing heavy components like
t h ese, anc hor vehicle t o hoist o r add corr e­
sponding weights to maintain the center of
grav ity. Oth erwise, the ve hicle might ti lt or
s li p off the hois t, causing s eriou s perso na l

(D Note
- Be awar e of the fo llowing poi nts before lift­
i ng t he vehicle:
- The vehicle should never be lifted or
jacked up from underneath the engine oil pan , the transmission housing, the front
or rear axle or the body side members .
This could lead to serious damage.
- To avoid damage to the unde rbody or
chassis frame, a rubber pad must be in­
serted between the floor jack and the lift
points.
- Before driv ing over a workshop hoist,
check that the vehicle weight does not
exceed the permissible lifting capacity of
the hoist .
- Before driving over a workshop hoist, en­

Emergency situations
373

CXl CXl .... N ,.__
N .... 0 N > 00
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 other 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 applicable 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::> page 316 .
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 an­
other properly equipped and qualified work­
shop.
- 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 . The radiator fan switches on au ­
tomatically when the coolant reaches a cer­
tain temperature and will continue to run
until the coolant temperature drops.
- Always switch off the ignition before anyone
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) and the park brake is applied .
