Electronic speed
limiter
Your veh icle may be factory equipped with
tires that are rated for a maximum speed of
130 mph (210 km/h) . Th is is less than the
maximum speed of you r vehicle. To reduce the
ri sk of s udden tire failure and loss of control if
t he veh icle is ope rated at excessive speeds,
your vehicle also has an electronic speed lim it
er . The electronic speed limiter prevents yo ur
ve hicle from going faster than the tire speed
rating. For more informat ion

If the engine contro l unit receives fa ulty vehi
cle road speed signals, the Malfunction Indi
cator Lamp (MIL)

occ urs, contact the nearest authorized Aud i
dealer for assistance.
A WARNING
Always observe the posted speed limits
and ad just you r speed to suit p revailing
road, t raff ic and weather conditions. Never
drive your vehicle faster than the maxi

Speed warning system
Overview
The speed warning system helps you to keep
your driving speed below a set speed limit.
The speed warning system wa rns if the driver
exceeds a prev iously stored maxim um speed.
A warning tone will sound as soon as the vehi-
Dri ver information di spla y 2 7
cle speed exceeds the set speed by about
3 mph (3 km/h). At the same time, a warning
symbol appears in the display. The symbo l's
appearance might be different in some mod
els.
The speed warning system has two warning
thresholds that funct ion independent ly of
each other and that have somewhat different purposes:
Speed warning 1
You can use speed warning 1 to set the maxi
mum speed while you are driving. This setting
will remain in effect until yo u turn off the ign i
tion, assuming that you have not changed or reset the setting.
The . (USA mode ls)/ . (Canada models)
speed warning symbo l in the warning 1 dis
play appears when you exceed the maximum
speed . It goes out when the speed falls be low
the stored maximum speed .
The speed warning symbol will also go o ut if
the speed exceeds the stored maximum speed
by more than about 2S mph (40 km/h) for at
least 10 seconds . The stored max imum speed
is deleted.
Speed w arning 2
Storing warning 2 is recommended if yo u al
ways want to be reminded of a certain speed,
for example whe n you are trave ling in a coun
try that has a genera l maximum speed limit,
o r i f you do not want to exceed a specified
speed for wi nte r tir es.
The . (USA models) . (Canada models)
speed warning 2 symbol appears in the dis
play when yo u exceed the sto red speed limit.
Unlik e warning 1, it will not go out unt il the
vehicle speed drops below the s to red speed
li mi t.
