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).
Cruise control system

Ill (Canada mode ls) indicator light appear in the

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.
(0 Tips
The b rake lights turn on when the brakes are
app lied automatically .

Overriding the speed
Applies to: vehicles with cruise control system
You can press the acce lerator pedal down to in
c rease yo ur speed, for example if you want to
pass someone. The speed yo u sto red earl ie r w ill

(D Note
The sensors can be displaced by impacts or
damage to the bumper , whee l housing and

cruise control. Have an authorized Audi dea ler
or authorized Audi Service Fac ility check their
function .
In curves
Applies to: vehicles with Audi adaptive cruise control
Fig . 9 1 Exa mple: drivin g in to a curve
When driving into a curve<=> fig. 91 and ou t of a

A WARNING
- Read the warnings on c::> & in General infor
mation on page 97
and on c::> & in Descrip
tion on page 24 .
- Pay attention to traffic and the area around
your vehicle when predictive control is switched on. The driver is always responsi
ble for correctly assessing the traffic situa
tion.
- There is an increase in the risk of an acci
dent, because the system does not consider
"right of way" rules and also does not re
spond to traffic lights .
- The system only considers traffic signs that
give a speed limit.
Assist
- The permitted speed can be exceeded if the
adaptation to a speed limit is incorrect. The
driver is responsible for adhering to the per
mitted speed.
- The speed at which a curve is driven through
does not necessarily match your own driving
style . Brake the vehicle yourself when need
ed to reduce the risk of an accident.
(D Tips
-If a speed limit is detected, the stored
speed is also adjusted in the speedometer
LED line when the adaptive cruise control is
not active.
- The adaptation by the system depends on
the driving mode set in drive select* .
- Switching off predictive control, for exam
ple when driving in low traffic zones, does
not cause the adaptive cruise control to
switch off .
-After switching on the ignition, the system
initially adjusts to a speed of 80 mph
(130 km/h) when driving onto highways
without a speed limit. Then the system ad
justs to the last speed stored by the driver.
- There is no adaptation to speed limits when
driving through highway interchanges and
when driving on or off the expressway.
- There is no predictive control at speed limits
under 20 mph (30 km/h).
- If a speed limit is only detected by the cam
era and the actual speed is significantly
higher, then the speed limit will blink in the
display until you have reached the required
speed
c::> page 25.
- Incorrect values from the camera-based traffic sign recognition* or outdated naviga
tion system map data can lead to incorrect
or implausible control.
- When route guidance is switched on, the
system adapts to the route provided by the
navigation system. Driving without route
guidance or leaving a route can result in im
plausible control.
- The system switches
off when outside of a
road system that is recorded in the naviga
tion system map data.

Description
A pp lies to: ve hicles with Aud i adapt ive cruise co ntrol
Congestion assist supports the driver when driv

In a speed range under 40 mph (65 km/h), con
gestion assist can he lp to keep the vehicle within
a lane calculated by the system. Within the limits
of the system, the system controls the steering
automat ica lly when adaptive cruise contro l is
switched on. Since congest ion assist is only a n
ass ist system, the driver must always keep his or
her hands on the steering wheel and be ready to
stee r. The driver can override the control at any
time by actively steering.
The system is designed for driving on express
ways and highways .

If congestion assist was deactivated through the
Infotainment system, you can continue operating

Always switch off congestion assist in the
following situations:
