Driving

— The vehicle battery will gradually drain if
the vehicle is not driven for long periods of
time, or if electrical equipment is used
when the engine is not running. To ensure
that the vehicle can still be started, the
electrical equipment will be limited or
switched off.
IC Te lt
B Drive system: malfunction! Safely stop vehi-
cle
There is a malfunction in the drive system. The
brake booster and the power steering may stop
working. Stop the vehicle immediately or as soon
as possible and do not continue driving. Secure
the vehicle against rolling before exiting the vehi-
cle > page 104. Have the problem corrected by
an
authorized Audi dealer or authorized Audi
Service Facility.
B Drive system: malfunction! Please contact
Service
There is a malfunction in the drive system. Drive
slowly to an authorized Audi dealer or authorized
Audi Service Facility to have the malfunction cor-
rected.
Start/Stop system
Applies to: vehicles with Start/Stop system
The Start/Stop system can help increase fuel
economy and reduce CO2 emissions.
In Start/Stop mode, the engine shuts off auto-
matically when stopped, for example at a traffic
light. If certain conditions are met, the engine
may stop before the vehicle has come to a com-
plete stop. If you press the accelerator pedal
when this happens, the engine will start and driv-
ing power will be transmitted.
The ignition and important assist systems such
as the brake booster will remain available during
the Stop phase. The engine will restart automati-
cally when needed.
The Start/Stop system is automatically activated
once
the ignition is switched on.
Switching the Start/Stop system off and on
The @)* button is located above the selector lev-
er in the center console. The LED in the button
turns on when the function is switched off.
> Press (A)>F to switch the system on or off.
If you switch the system off during a Stop phase,
the engine will start again automatically.
Basic requirements
— The driver’s door and the hood must be closed
and the driver’s safety belt must be fastened.
—"P","N", or"D" must be engaged.
—The steering wheel must not be turned far in ei-
ther direction.
— The vehicle must have driven faster than 2 mph
(3 km/h) since the last time it stopped.
— The vehicle is not in trailer mode.
@) Note
Always switch the Start/Stop system off when
driving through water > page 111.
G) Tips
— Depending on the driving situation, the en-
gine may already stop when coasting before
the vehicle has come to a complete stop.
—If you select the "D" position after shifting
into reverse, the vehicle must be driven fast-
er than 6 mph (10 km/h) in order for the
Start/Stop system to become active again.
This makes it possible to maneuver without
stopping the engine.
Stopping and starting the engine
Applies to: vehicles with Start/Stop system
> Press and hold the brake pedal until the vehicle
has stopped. The @J indicator light appears in
the instrument cluster once the engine stops
automatically.
> The engine starts again when you remove your
foot from the brake pedal. The indicator light
turns off.
If the parking brake is set, the engine will only
start again when the accelerator pedal is pressed. >

Driving

@ Tips
— Press the brake pedal during a Stop phase
to keep the vehicle from rolling.
— The ignition will turn off if you press the
START ENGINE STOP} button during a Stop


phase.
— If you leave the vehicle briefly during a Stop
phase and then enter again, the driver's
door must be closed and the safety belt
must be fastened in order for the engine to
be able to restart.
— You can control if the engine will stop or not
by reducing or increasing the amount of
force you use to press the brake pedal. For
example, if you only lightly press on the
brake pedal in stop-and-go traffic or when
turning, the engine will not switch off when
the vehicle is stationary. If you press the
brake pedal harder, the engine will switch
off.
Starting and stopping the engine automat-
ically
Applies to: vehicles with Start/Stop system
The system checks if certain conditions are met
before and during the Stop phase, and deter-
mines if the engine stops and how long it re-
mains stopped. For example, if power usage is
high, the engine will not be stopped. Along with
other conditions, the following factors influence
the automatic engine start or stop:
— Environmental conditions (slopes, inclines, ele-
vation, temperature)
— Battery (charge status, temperature, power us-
age)
— Engine temperature
— Assist systems
— Driving behavior
Depending on the engine, the indicator light
may appear if the engine is not stopped.
Applies to: vehicles with Start/Stop system
Drive system: please start the vehicle manually
112
This message appears when specific conditions
are not met during a Stop phase. The Start/Stop
system will not be able to restart the engine. The
engine must be started with the
START ENGINE STOP] button.


Vehicle starting system: malfunction! Please
contact Service
There is a malfunction in the Start/Stop system.
Drive the vehicle to an authorized Audi dealer or
authorized Service Facility as soon as possible to
have the malfunction corrected.
Brakes
General information
You can apply the vehicle's brakes using the brake
pedal.
Operating noise
Noises may occur when braking depending on the
speed, braking force, and outside conditions such
as temperature and humidity.
Braking effect
The response time from the brakes depends on
the weather and environmental conditions. To
ensure the optimal braking effect, the brake sys-
tem is cleaned at regular intervals. This is done
by applying the brake pads to the brake rotors for
a short period of time when driving at high
speeds when the windshield wipers are switched
on.
If the brake system becomes damp, for example
after driving in heavy rain, the braking effect may
be delayed. Other factors that could temporarily
increase the response time of the brakes include:
— Wet conditions
— Low temperatures, ice, and snow
— Roads covered in salt
— Dirty brake pads
Corrosion
Corrosion may form on the brake rotors if there is
no heavy braking, if the vehicle is not driven for
long periods of time, or if the vehicle is not driv-
en frequently or for long distances. In this case, >
