mission; put manual transmission in
first gear=> &.

vehicle.

& 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 flasher on and use other
warning devices to alert other motorists.
• Make sure that passengers wait in a safe place away from the
vehicle and well away from the roadway 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 being changed. When one front wheel is lifted off the ground, placing the automatic
transmission in "P" (Park), or engaging a gear in a manual trans­
mission will
not prevent the vehicle from moving.
• Before you change a wheel, be sure the ground is level and
firm. If necessary, use a sturdy board under the jack .
• After installing the spare wheel, make sure that you remount
the flat tire/wheel in its storage area properly and tighten the
knurled retaining screw securely. •

ri zed Audi dealer replace burned out bulbs for you.
It is becoming increasingly more and more difficu lt to rep lace vehicle

removed before you are able to get to the bu lb. This app lies espec ially
to the l igh t bu lbs in the front of your car whi ch you can o nly rea ch
through the engine compartment .
Sheet metal and bu lb holders can have sharp edges that can ca use
serious cuts, and parts must be correctly taken apart and the n prop­
erly put back together to he lp prevent b reakage of parts and long
term damage from wate r that can enter housings that have not been
p roperly resealed.
For your safety, we recommend that you have you r authorized Audi
deale r replace any bu lbs fo r you, since your dealer has the proper
too ls, the cor rec t bu lbs and the expertise .
