sumes excessive amounts of oil, we recom ­
mend that you consu lt an autho rized Aud i
dealer to have the cause of your concern
properly d iagnosed . Keep in mind that the
accurate measurement of oil consumption
r equ ires great care and may take some
time . An authorized Audi dea ler has instruc­
tions about how to measure oil consump­
tion a ccura tely .

Checking and Filling
T he oil consumpt ion of the engine may be up to
1/2 quart per 600 miles (0 .5 liters/1,000 km),
depending on driving style and ope rational cond i­
tions. Consumption may be higher during the

,.. Activate the parking brake to prevent the vehi­
cle from rolling unintentionally .
,.. Move the selector lever to the P position.
,.. Find the
m arki ng (imprint) on the sill that is
nearest the wheel that will be changed
c> fig . 168. Behind the marking, there is a li ft ­
i ng po int
on the sill for the vehicle jack.
,.. Turn the
veh icl e jack located under the lifting
point on the s ill to ra ise the jack until the jaw

,.. Align the vehicle jack so the jaw @covers the
notch and the base plate @ is flat on the floor .
The base plate @ must be
vertical under the
lifting point @.
,.. Install the rod on the vehicle jack : Insert the
rod into the opening on the handwheel. Turn
the rod left or right to secure it .
216
,.. Continue raising the jack with the rod until the
wheel lifts off the ground slight ly.
Position the vehicle jack
only under the designat ­
ed lifting points on the sill
c> fig. 168. T here is ex­
actly
one l ocation fo r each wheel. The jack must
not be positioned at any other location
c> ,1. ¢(D .
So ft gr ound under the jack can cause the ve hicle
to slip off the jack . Always p lace the jack on firm
ground. Use a flat, stab le support if necessary .
Use a non-slip surface such as a rubber mat on a
s lipp ery s urface such as tile.
A WARNING -
-You or your passengers could be injured
while changing a wheel if you do not follow
these safety precautions:
- Position the vehicle jack only at the des ig­
nated lifting points and align the jack .
Otherwise, the vehicle jack could slip and
cause an injury if it does not have suffi ­
cient hold on the vehicle.
- Use only the jack* supplied w ith your veh i­
cle to raise the vehicle . If you use a jack
from a different vehicle, your vehicle may
slip off the jack - risk of injury!
- Do not use the jack* supplied with your ve­
hicle to raise other vehicles, as these may
slip off the jack - risk of injury!
- A soft or unstab le surface under the jack
may cause the vehicle to slip off the jack.
Always provide a firm base for the jack on
the gro und .
If necessary, use a sturdy
board unde r the jack.
- On hard, slippery surface (such as t iles)
use a rubber mat or similar to prevent the
jac k from slipp ing .

jack
The vehicle may only be lifted at the lifting
points illustrated.
Fig. 181 Front lifting point
F ig . 182 Rear lifting point
• Read and heed WARNING¢,&..
I
• Locate lifting points ¢fig.181 and ¢ fig. 182.
Emergency situations
• Adjust lifting arms of workshop hoist or floor
jack to match vehicle lifting points .
• Insert a rubber pad between the floor jack/
workshop hoist and the lifting points .
If you must lift your vehicle with a floor jack to
work underneath, be sure the vehicle is safely
supported on stands intended for this purpose .
Front lifting point
T he lifting point is located on the floor pan rein­
forcement about at the same level as the jack
mounting point ¢
fig. 181. Do not lift the vehi­
cle at the vertical sill reinforcement .
Rear lifting point
The lifting point is located on the vertical rein­
forcement of the lower sill for the on board jack

Lifting with vehicle jack
Refer to¢ page 216.
&_ WARNING
- To reduce the risk of se rious injury and vehi­
cle damage.
- Always lift the vehicle on ly at the special
workshop hoist and floor jack lift points il­
lustrated ¢
fig. 181 and ¢ fig. 182.
- Failure to lift the vehicle at these points
could cause the vehicle to tilt or fall from
a lift if there is a change in vehicle weight
distribution and balance . This might hap­
pen, for example, when heavy compo­
nents such as the engine block or trans­
mission are removed.
- When remov ing heavy components like
these, anchor vehicle to hoist or add corre­
sponding weights to maintain the center of
gravity. Otherw ise, the vehicle might tilt or
slip off the hoist, causing serious personal
injury .
