Difficult ter rain
When driving in unfamiliar areas and offroad,
drive slowly and keep on the watch for unexpect­
ed obstacles (such as potholes, rocks, tree
stumps, etc.).
To prevent the veh icle from bottoming out and to
reduce the risk of underbody damage, you sho uld
d rive across uneven ground on only one side of
the veh icle so that only two of your wheels cross
the uneve n are a, instead of driving across the
center of the uneven area with a ll four wheels .
Drive quick ly through sandy or marshy off-road
sections and do not stop, if at all possible.

Automatic transmission
Introduction
Applies to: vehicles with automatic transm issions
The automat ic transmission is controlled elec­
tronically. The transmission shifts up o r down au­
tomatically depend ing on which drive program is
se lected .
When a
moderate drivi ng style is used, the
transmission selects the most economical driving
mode. The transmiss ion upshifts at a lower RPM
and downshifts at a higher RPM to improve fuel
efficiency .
The transm ission switches to a sporty mode after
a kick-down or when the driver uses a
s po rty
d rivi ng style
character ized by quick accelerator
pedal movements, heavy acceleration, frequent
D rivi ng
changes in sp eed and traveling at the maximum
speed.
If des ired, t he d river can also se lect the gea rs
manually (tiptronic mo de) ¢ page 94 .
S tronic transmission
The S tron ic is a dual-clutch transmission . Power
is transferred using two clutches that work inde­
pendent ly from one another. They rep lace the
torque conve rter used in convent io nal automatic
transm issions and allow the vehicle to accelerate
without a noticeable interruption in traction.
tiptronic transmission
In th e tiptronic transmission, power is t ransfer­
red by a torque conve rter.

In the no rmal mode D, the transmission a uto­
matica lly selects the suitab le gear ratio. It de­
pends on eng ine load, vehicle speed and driving
style.
Select the

vehicle makes full use of the engine's power.
Shifting may become noticeable when accelerat­ ing.
The S selector lever position engages automati­
cally when you se lect
Dynamic mode in drive se­
l ect*.
A WARNING
Read and follow all WARNINGS.
-The vehicle can roll even if the ignition is
switched off.
-Power is sti ll transmitted to the wheels
when the eng ine is running at idle . To pre­
vent the veh icle from "creeping", you must
keep your foot on the brake in all selector
lever positions (except P and N) when the
engine is running .
-Before opening the hood, select the P selec­
tor lever position and set the parking brake.
This reduces the risk of an accident. Always
read and fo llow the applicable warnings
¢ page 323, Working in the engine com­
partment.
@ Tips
If you accidentally se lect N wh ile d riving, take
your foot off the accelerator pedal and wa it
for the engine to slow down to idle before se­
lect ing Dor S.

@ Tips
- If you shift to the next lowest gear, the
transmission will only shift if the engine will
not be over-revved.
- With kick-down, the transmission shifts to a
lower gear, depending on vehicle speed and

is running in emergency mode.
Kick-down
Applies to: vehicles with automatic transm issions
Kick-down enables maximum acceleration.
When you press the accelerator pedal down be­
yond the resistance point, the automatic trans ­
mission downshifts into a lower gear and the en­
gine utilizes its full power , depending on vehicle
speed and engine RPM. It shifts up into the next
higher gear once the maximum specified engine
RPM is reached.
A WARNING
Please note that the wheels could spin on
slick or slippery roads when kick-down is ac­
tive .

Electronic speed Limiter
Your vehicle may be factory equipped with tires
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
lim iter prevents your vehicle from going faster
than the t ire speed rating. For mo re information

The speed warning system helps you to stay be­
low a specified maximum speed that can be set,
changed or deleted in the Infotainment system.

operation. You are always responsible for
your speed and the distance between your
vehicle and other vehicles.
- For safety reasons, cruise control should not be used in the city, in stop-and-go traffic, on
winding roads and when road conditions are poor (such as ice, fog, gravel, heavy rain and
hydroplaning), because th is increases the
risk of an accident.
- Switch the cruise control off temporar ily
when driving in turn ing lanes, h ighway exits

- Please note that unconsciously "resting"
your foot on the accelerator pedal prevents the cruise control from b raking. This is be­
ca use p ressing the acce le ra to r peda l ove r­
rides the cruise contro l system.
- If a brake system ma lf u nction such as over­
heating occurs when the c ruise contro l sys­
tem is switched on, the braking function in
the system may be switched off . The rest of
the cruise control system functions remain
act ive as long as the
@;\l)M~ (USA models) /

Before driving downhill a long distance on a
steep hill, decrease your speed and select a
lower gear. Th is makes use of the eng ine
braking effect and relieves the brakes.
(D} Tips
-Applies to: vehicles with manual transmis­ sion: The set speed can on ly be reached if
the engaged gear permits it so that the en­
gine is not over-rewed and will run smooth­ ly. Therefore, s hift into the higher or lower
gear in a timely manner .
- The brake lights turn on when the brakes are applied automatically.
Changing the speed
Applies to: vehicles with cruise control system

.. To increase or decrease the speed quick ly, hold
the lever toward 0 10 to the first or second
level unt il the desired speed is reached .
Overriding the speed
Applies to : vehicles with cruise control system
You can press the acce lerator pedal to increase
you r speed, fo r example if you want to pass
someone. The speed you set earl ier will resume
as soon as you release the acce lera to r pedal.
However, if you are exceeding the stored speed
by a considerable amount fo r a long time, the

General information
The pred ictive eff ic iency assist helps the driver to

of curves) from the navigation system*. Informa­
tion from the camera-based traff ic sign recogni­

r;;:;ipage 104.
The messages displayed depend on the naviga­

tification by the traffic sign recognition*.
When adaptive cruise contro l* is switched off,
the predictive efficiency assist only provides noti­
fications without controlled interventions. When
adaptive cruise control* is switched on, the sys­
tem responds to upcoming situations automati­

Audi adaptive cruise
control
Description
A ppl ie s to: ve hicles w ith Audi adaptive cruise co ntro l
Fig. 107 Detect ion range
The adaptive cruise control system is a combina­
tion of speed and distance regulation.
It assists
the dr iver by both regulating the speed and
maintaining a distance to the vehicle driving
ahead, within the limits of the system . If the sys­
tem detects a vehicle driving ahead, the adaptive
cru ise control can brake and acce lerate your vehi­
cle. This increases driving comfort dur ing long
tr ips on highways and in stop-and -go traff ic (au ­
tomatic transmission*).
What can adaptive cruise control do?
The adaptive cruise contro l system uses video, ra­
dar, ultrasound and navigation data. Veh icles
108
driving ahead can be recognized up to 650 feet
(200 m) away.
P red ictive functions offer the driver additional
comfort and contribute to the reduction in fue l
consumption and CO2 emiss ions
r:!> page 115.
On open roads with no traffic , it functions like a
c ruise control system. The stored speed is main­
tained . When approaching a vehicle driving
ahead, the adaptive cruise contro l system auto­
matically brakes to match that vehicle's speed
and then maintains the set distance . As soon as
the system does not detect a vehicle dr iving
ahead, adaptive cruise control accelerates up to
the stored speed.
App lies to: vehicles wit h auto matic transmissions
In stop-and-go traffic, adaptive cruise control can
brake until the veh icle is stationary and then can
also start driving again automat ically under cer­
ta in cond itions
r:!> page 112 .
In traffic jams or s top-and-go traffic, traffic jam
ass ist can ass ist the driver
r:!> page 116.
Which functions can be controlled?
When you switch adapt ive cru ise control on, you
can set the current speed as the "contro l speed"
r:!> page 110, Switching on/off.
When dr iving, you can stop cruise control
c:>page 113 or change the speed c::;,page 112 at
any time .
You can also set the distance to the vehicle driv­ i ng ahead and set the driving mode of the adap­
tive cru ise cont rol
