Switching the ignition on/off
If you would like to switch the ignition on with­
out starting the engine, follow these steps:
.,. Press the
I STAR T ENGINE STOPI button with·
out pressing the brake pedal.
.,. To switch the ignition off, press the button
again. The needle in the tachometer moves into
the
OFF position.
The prewarming runs automatically in diesel
vehicles when the ignition is switched on.
Equipment that uses a lot of electricity is switch­
ed off temporarily when you start the engine.
If the engine should not start immediately, the
starting process is automatically stopped after a
short time. Repeat starting procedure .
Start-Stop-System*
Note the information in c> page 79, Start-Stop­
System.
A WARNING
- Never allow the engine to run in confined
spaces, because this increases the risk of as­
phyxiation.
- Never turn off the engine before the vehicle
has come to a complete stop.
- The brake booster and power steering no
longer function when you stop the engine.
You must use more force when braking or
steering. Because you cannot brake and
steer as you usually would, this could lead
to accidents and serious injuries. These
functions are still active if the Start-Stop­
System* has stopped the engine.
(D Note
Avoid high engine speed, full throttle, and
heavy engine load as long as the engine has
not reached operating temperature yet. You
could damage the engine.
@ For the sake of the environment
Do not let the engine run while parked to
warm up. Begin driving immediately. This re­
duces unnecessary emissions.
-
Driving
{!) Tips
- After starting a cold engine, there may be a
brief period of increased noise because the
oil pressure must first build up in the hy­
draulic valve adjusters. This is normal and
not a cause for concern .
- If you leave the vehicle with the ignition
switched on, the ignition will switch off af­
ter a certain amount of time. Make sure that electrical equipment such as the exterior
lights are switched off.
Stopping the engine
.,. Bring your vehicle to a complete stop.
.,. Move the selector lever to the P or N position.
.. Press the
!START ENGINE STOP ! button
r:!>poge 74, fig. 80.
Steering lock
The steering locks when you turn the engine off
using the
I START ENGINE STOPI button and
open the driver's door. The locked steering helps
prevent vehicle theft.
Emergency off
If necessary, the engine can be switched off with
the selector lever in the R or D/S position. The
engine stops if you press and hold the
!START ENGINE STOP ! button at speeds below
6 mph (10 km/h) and press the brake pedal.
A WARNING
-Never turn off the engine until the vehicle
has come to a complete stop.
- The brake booster and power steering only
work when the engine is running.
If the en­
gine is off, you have to use more force when
steering or braking. Because you cannot
steer and brake as you usually would, this
could lead to crashes and serious injuries.
- For safety reasons, you should always park
your vehicle with the selector lever in P.
Otherwise, the vehicle could inadvertently
roll away.
-
75

Driving
-After the engine has been sw itched off, the
rad iator fan can continue to run for up to 10
minutes - even with the ign ition switched
off . It ca n also switch on again after some
t ime if the coolant temperature rises as the
r esult of a heat buildup o r if the eng ine is
hot and the eng ine compartme nt is addi­
ti onal ly he ated by the su n's rays.
@ Note
Do not stop the engine immed iate ly after
hard o r ex tended d riving. Keep the engine
running for app rox im ately two m inutes to
prevent exces sive hea t build-up.

Speed warning system
Introduction
The speed warning system helps you to stay un­
der a specified maximum speed.
The speed warn ing system warns you if you are
exceed ing the maximum speed that you have set.
You will hear a warn ing tone when your speed ex­
ceeds the s tored value by approx imately 3 mph
(3 km/h) . An indicator light . (USA models)/ .
(Canada models) in the instrume nt cl uste r d is­
play a lso tu rns on at t he same time. The indicator
lig ht •• tur ns off when the speed decreases
below the stored maximum speed.
Setting a th reshold is recommended if yo u wo uld
lik e to be rem inded whe n you reach a cer tain
ma ximum speed. Situations where you may want
to do so incl ude driving in a co untry with a gener ­
al speed limit or if there is a spec ified maximum
speed for winter tires.
@ Tips
Eve n though your vehicle is eq uipped w ith a
speed warning system, yo u should still watch
the speedometer to make sure you are not
driving faster than the speed lim it.
Setting the threshold
You can set, change and delete the warning
threshold in the Infotainment system.

display may vary, depending on the type of dis­
play in your vehicle .
This information is also shown briefly in the
Head-up display*.
The speed is kept constant by modifying engine
power or through an active brake intervent ion.
A WARNING
- Always pay attention to the traffic around
you when the cruise control is in operation.
You are always responsible for your speed
82
-
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 this increases the
r isk of an accident.
- Switch the cruise control off temporarily
when dr iving in turning lanes, highway exits
or in construction zones .
- Please note that unconsciously "resting"
your foot on the accelerator pedal prevents the cruise contro l from braking. This is due
to the control system being overridden by
the driver's acceleration.
- If a brake system malfunction such as over­
heating occurs when the cruise control sys­
tem is switched on, the braking function in
the system may be switched off. The rest of
the cruise control system functions remain active as long as the indicator light
1ij;(i)~14 (USA models) 1B (Canada models) is
on .
(D Tips
The brake lights illuminate as soon as the
brakes apply automat ically.

sired speed is disp layed.
You can also press the accelerator pedal down to increase your speed, e .g . if you want to pass
someone . The speed you saved earlier will re­
sume as soon as you release the accelerator ped­
al.
If, however, you exceed your saved speed by
6 mph (10 km/h) for longer than 5 minutes, the
cruise contro l will turn off temporarily. The green

Audi adaptive cruise control and braking guard
Audi braking guard
Description
Applies to vehicles: w ith Audi adaptive cruise co ntro l
Fig. 98 Instrument cluster: approach warning
Braking guard uses radar sensors and a video
camera . It also functions within the limits of the
system when adaptive cruise control is switched
off .
What can braking guard do?
When detected in time, the system can assess
situations when a vehicle ahead brakes suddenly
or if your own vehicle is traveling at a high speed
and approaching a vehicle up ahead that is mov­
ing more slowly . Braking guard does not react if
it cannot detect the situat ion.
The system advises you of various situations:
- The
distance warning is given if you are too
close to the vehicle ahead for a long time.
If the
vehicle ahead brakes sharply, you will not be
able to avo id a coll is ion. The indicator light.
in the display comes on .
- The
approach warning is given when a detected
vehicle up ahead in your lane is moving much
more slowly than you are or if it brakes sharply .
When this warning is g iven, it may only be pos­
sible to avo id a collision by swerving or braking
sharp ly. Th e indicator light. and indicator in
the display will warn you about the danger
qfig. 98. You will also hear an acoustic signal.
If you do not react fast enough or do not react at
all to t he situation, braking guard will intervene
by braking.
l ) Thi s is not ava ilab le in some co un tri es .
90
-If a collision is imminent, the system will first
provide an
acute warning by briefly and sharply
app lying the brakes.
- If you do not react to the acute warning, brak­
ing guard can brake with increasing force with­
in the limits of the system. This reduces the ve­
hicle speed in the event of a collision.
- The system can initiate maximum braking

high speeds occurs only in vehicles with adap­
tive cruise control and side assist (pre sense
plus) .
- If the braking guard senses that you are not
braking hard enough when a collision is immi­
nent, it can increase the braking force .
- The pre sense functions also engage when a
collision is imminent

Which functions can be controlled?
You can switch braking guard and the distance/
approach warning on or off in the MMI

A WARNING
Lack of attent ion can cause collisions, other
accidents and serious personal injuries . The
b ra king guard is an assist system and cannot
prevent a collision by itself. The driver must
always intervene . The driver is always respon­
sib le for braking at the correct time .
- Always pay close atten tion to traffic, even
when the braking guard is switched on. Be
ready to intervene and be ready to take
comp lete contro l whenever necessary. Al­
ways keep the safe and legal distance be­
tween your vehicle and vehicles up ahead.
- Braking guard works with in limits and will
not respond outside the system limits, for
example when approaching a stopped vehi­
cle or stationary obstacle (end of a traffic
jam or vehicle that has broken down in traf­
fic) .
- Always remember that the radar sensor for
