Please note that the wheels could spin on
slick or slippery roads when kick-down is ac­
tive.

A WARNING
-Always adapt your driving to the traffic flow.
- Only use the Launch control program when
road and traffic conditions allow it and oth­
er drivers will not be endangered or both­
ered by your driving and the vehicle's accel­
eration.
- Please note that the drive wheels can spin
and the vehicle can break away when sport
mode is switched on, especially when the

not be available for a few minutes. It will be
available again after a cool-down period.
- When accelerating using the launch control
program, all vehicle parts are subject to
heavy loads. This can lead to increased
wear.

Assist Electronic speed limiter
Your vehicle may be factory equipped with t ires
that are rated for a maximum speed of 130 mph (210 km/h). This is less than the maximum speed
of your vehicle. To reduce the risk of sudden tire
failure and loss of control if the vehicle is operat­
ed at excessive speeds, your vehicle also has an
electronic speed limiter . The electronic speed
limiter prevents your vehicle from going faster
than the t ire speed rating. For mo re information
¢page 317.
If the engine control unit receives faulty vehicle
road speed s ignals, the Malfunction Indicator
L amp (M IL)
¢..ij will illuminate. If this occurs,
contact the nearest autho rized Audi dealer for
assistance.
_& WARNING
Always observe the posted speed limits and
adjust you r speed to suit prevailing road, traf­
fic and weather condit ions. Never drive your
vehicle faster than the max imum speed rating
of the tires installed.
Speed warning system
Introduction
Applies to: vehicles with speed warning system
The speed warning system helps you to stay un­
der a specified maximum speed. -
The
speed warning system warns you if you are
exceeding the maximum speed that you have
stored . You will hear a warning tone when yo ur
speed exceeds the sto red va lue by approximate ly
3 mp h (3 km/h). The indi cator light also tur ns on
in the instrument cluster display
Eel (USA mod­
e ls)/
Hll (Canada mode ls) as well as the message
Manually set speed limit XXX mph (km /h ) ex­
c eeded .
The ind icator light [01 / (OJ turns off
when the speed decreases below the stored max­
imum speed.
Sett ing a threshold is recommended if you would
like to be reminded when you reach a certain
maximum speed. Situations where you may want
A ss ist
to do so include driving in a co untry with a gener­
al speed limit or if there is a specified maximum
speed for winte r tires.
(D Tips
Regardless of t he speed warning system, you
s h ou ld always monitor your speed using the
speedometer and make s ure yo u are fo llow ing
the lega l speed limit.
Setting the warning threshold
Appl ies to : vehicles with speed warni ng system
You can set, change and delete the warning
threshold in the Infotainment system.
.,. Sele ct in the Infotai nment system: I MENU ! but­
ton
> Vehicle > left control b utton > Driver as­
sistance
> Speed warning > Manu al.
You can set a ny thresho ld between 20 mp h
(30 km/h) and lS0 mph (240 km/h) . Settings
can eac h be adjusted in increments of 5 mph (10
km/h).

The stored speed and the [ij;ji j~i4 (USA models)/
Ill (Canada mode ls) indicator light appear in the
instrument cluster disp lay . An add itiona l indica­
tor appears in the Head -up display*.
The speed is maintained by modifying engine power or through an active brake intervention.
A WARNING
- Always pay attention to the traffic around
you when the cruise control system is in op­
eration. You are always responsible for your
speed and the distance between your vehi­
cle and other veh icles .
- For safety reasons, cruise control should not
be used in the city, in stop-and-go traffic, on
winding roads and when road condit ions are
poo r (such as ice, fog, gravel, heavy rain and
hydroplaning), because t his increases the
risk of an accident.
- Switch the cruise cont rol off temporar ily
when d riving i n turn ing lanes, h ighway exits
or in construction zones .
- Please note tha t unconsciously "resting"
yo ur foot on the accelerator pedal prevents
the cruise control from braking. This is be ­
cause pressing the acce lerato r pedal ove r­
rides the cruise contro l system.
- If a brake system ma lf u nction such as over ­
heating occurs when the cruise control sys­
tem is sw itched on, the braking function in
the system may be sw itched off. The rest of
the cruise control system functions remain
active as long as the
[ij;(l)~i4 (USA models) I
i:I (Canada models) indicator light is on.
(D Note
Before driving a long d istance on a steep
downward hill, decrease your speed and se­
lect a lower driving gea r. This makes use of
the engine b raking effect and relieves the
brakes.
