.&_ WARNING
Improper use of the vehicle jack can cause se­
r ious personal injuries.
- Never use the screw driver hex head to
tighten wheel bolts, since the bolts cannot
attain the necessary tightening torque if you
use the hex head, potentially causing an ac­
cident.
- T he factory-supplied jack is intended only
for your vehicle model. Under no circum­
stances should it be used to lift heavy
vehicles or other loads; you risk injuring
yourself.
- Never start the engine when the vehicle is
raised, which could cause an accident.
- Support the vehicle securely with appropri­
ate stands if work is to be performed under­
neath the vehicle; otherwise, there is a po­
tent ial risk for injury.
- Never use the jack supplied with your Audi
on another vehicle, particularly on a heavier
one. The jack is only suitable for use on the
vehicle it came w ith.
@ Tips
The vehicle jack* in your vehicle is mainte­
nance-free.

_& WARNING
You or your passengers could be injured while
changing a wheel if you do not follow these
safety precautions:
- If you have a flat tire, move a safe distance
off the road. Turn off the engine, turn the emergency flashers on and use other warn­
ing devices to alert other motorists.
- Make sure that passengers wait in a safe
place away from the vehicle and well away
from the road and traffic.
- To help prevent the vehicle from moving
suddenly and possibly slipping off the jack,
always fully set the parking brake and block
the wheel diagonally opposite the wheel be­
ing changed. When one front wheel is lifted
off the ground, placing the Automatic
