There is a malfunction in the ABS when :
• the warning/indicator light does not ill uminate when you switch
o n t he ign ition .
• the warning/indicator light does not go out after a few seconds .
• the warning/i ndicator light illu minates while driving .
Without the electronic assistance of the ABS , the brake system will
still respond and brake the car . Have the brake system checked and
restored to its full performance by an authorized Audi dealer as
soon as possible.

& WARNING
• If the ABS/ 8 (Canada models) warning light does not go out ,
or if it comes on while driving, the ABS system is not working
properly . The vehicle can then be stopped only with the brakes
operating without ABS support . You will not have the protection
ABS provides. Contact your Audi dealer as soon as possible.
• USA models : If both the BRAKE warning light and the ABS
warning light come on at the same time, the rear wheels could lock up first under hard braking. Rear wheel brake lock-up can
cause loss of vehicle control and an accident . Have your vehicle
repaired immediately by your authorized Audi dealer or a qualified
workshop. Drive slowly and avoid sudden , hard brake application .
• Canada models : If both the brake warning light ((DJ and the ABS
warning light
0 come on at the same time , the rear wheels could
lock up first under hard braking. Rear wheel brake lock-up can
cause loss of vehicle control and an accident . Have your vehicle
repaired immediately by your authorized Audi dealer or a qualified
workshop. Drive slowly and avoid sudden, hard brake
application. •

Appl ies to vehicles: wi th 6-speed automatic transm is sion
Fail-safe mode
If the tiptronic® suffers a malfunction, the fail-safe mode
maintains minimum driveability.
If there is a malfunct ion in t he system, the automatic transmiss ion
wi ll shift to the fai l- safe mode. Al l the segments in the display will
l ight up to indicate th is condi tion .
Display col ors inv ersed
If there's a ma lfunction in the system, the automatic transmission
wi ll shift to the fail -safe mode. The entire row of gear selector posi ­
t ions wi ll light up in the d isplay in inverse colors ( light background,
dark characters) to indicate this condition . If there is an electrical
f ailure, t he gear posi tion ind ica tor row wi ll turn blank .
You wi ll sti ll be able to put the se lected lever in any of the positions .
However, the transmission will remain in 4th gear when it is placed
in positions D and S.
[ i ] Tip s
• The electronic lock that protects t he reverse gear while driv ing is
inoperative when the transmission is in the fail- safe mode .
• The manua l shift program is inoperative in fail -safe mode .
• The transm ission aut omatically shif ts to and rema ins in 4t h gear
regard less of which of the forward gears is selected. This means
that it may not be possible to tow a t rai ler or to drive uphill on a
steep gradient. Reverse gear can sti ll be engaged.
• In case the engine goes out i t must b e restarted wi th the veh ic le
stationary and the selector lever in position ( Pl or (Nl.
• The 4 th gear remains engaged even whe n the veh icle comes to
a ha lt . T he transmission will respond with noticeable jolts as you

General information
Your vehicle is equipped with a electronically controlled continu ­
ously variable transmission
(multitronic,..l. Inside the multitronic™
system, the gear ratios are not shifted in finite steps as in a conven­
t ional automatic transmiss ion, but rat her
continuously . As a result,
engine power is applied smoothly and comfortably, and better fuel
econo my is ac hieved.
The transmission se lects the appropriate gear rat io (upshifts and
downshif tsl a utomat ical ly based on set dr iv ing progra ms
=> page 153, "Dynamic shift program (DSP)" .
You can a lso ma nua lly select a shift p rogram (tiptronic®)
=> page 154.
You shou ld note, that the multitronic transmission differs from a
conventiona l Aut omatic Transmiss io n . In the mu lt it ronic transm is ­
sion the engine power is transferred via a link -p late chain, rather
than by a conventi onal torque c onver ter . The multitronic transm is ­
s ion greatly reduces vehic le "creep"" when at a standst ill and the
transmission is in D Sor R.
