to rem ind you (e.g . whe n ch ang ing dr ivers) .,.

Canada models : The function cannot be
turned off.
It is activated a utomatica lly each
time the ignition is switched on.
Travel mod e (Canada models)*
The headlight beam is asymmetrical. This pro­
vides stronge r illum ination on the s ide of the
road on which you are driving . If you are driv ­
ing in a co untry that drives on the opposite
side of the road from your own country, this
will cause glare for oncoming drivers. To pre­
vent glare:
- Trave l mode must be selected in vehicles
with Xenon headlights*.
- In vehicles with halogen headlights, certain
areas of the head light lenses must be cov­
ered with waterproof adhesive covers that
prevent light from passing through. For
more information, please see your author­
ized Audi dealer or author ized repair facility .
@ Tips
When travel mode* is activated, a d isp lay
in the drive r information system ind icates
this each time you switch the ignit io n on .

(D Tips
T he ill umination for the instrument cluster
lights up w henever you switch on the igni­
tion with the vehicle headlights off. As the
day light fades, the instrument cluster i llu­
mination likewise dims automatica lly and
will go out completely when the outside li ght is very low. This feature is meant to
r emind you to switch on the head lights
whe n outside lig ht conditions become
p oor .
Adaptive light
Applies to vehicles: wi th adaptive light
Wh en driving around bends, the relevant area
of the road is be tter illuminated.
Fi g. 4 6 Adapt ive light w hen driv ing
Switching on adapt ive light
.. Turn t he light switch to AUTO ¢ page 49,
fig. 43 .
The adaptive lig ht system is a combin ation o f
the dynam ic and the static corneri ng lights.
Wi th the lights switched on, the dynamic cor ­
ner ing light adapts to driving on curves. This
is dependent upon t he vehicle speed and
steering ang le. This provides better lighting
through the curve. The system operates in a
speed range from approximate ly 6 mph
(10 km/h) to 68 mph (110 km/h) .
The static cornering light switches on at
speeds of up to approximately 25 mph

Notes o n these featur es
-The turn signals only work with the ignition
turned on. The indicator lights
II or Ill in
the instrument cluster
¢page 14 also b link.
- After you have turned a corner, the turn sig-
nal switches off automatica lly.
- The
high beam works only when the head­
lights are on. The indicator light

high beams are on.
- The
headlight flasher wo rks only as long as
you hold the lever -even if there are no
lights turned on. The indicator light
