Auxiliary climate control
Applies to: vehicles with auxiliary climate control
The auxiliary climate control system warms or
cools the vehicle interior. The vehicle will turn on
the auxiliary climate control system if needed,
depending on the last temperature that was set
with the climate control system controls. This
function can be used when the drive system is
switched off.
You can turn the auxiliary climate control system
on and off immediately in the Infotainment sys-
tem or set a timer.
Requirement: the high-voltage battery must have
a sufficient charge level and there must be
enough fuel in the tank.
@) Tips
— The temperature that the climate control
system adjusts to depends on the last tem-
perature you set in the climate control unit.
— Using the auxiliary climate control while
charging can also reduce the charge level of
the high-voltage battery.
— The auxiliary climate control system will not
turn on automatically or will turn off earlier
if the high-voltage battery charge or fuel
supply are too low, even if the vehicle is be-
ing charged at the time.

Driving

Switching the ignition on or off
If you would like to switch the ignition on or off
without starting the engine, follow these steps:
> Switching on: turn the key to position @.
> Switching off: turn the key to position ©).

ZA WARNING
—To reduce the risk of asphyxiation, never al-
low the engine to run in confined spaces.
— Never turn off the engine before the vehicle
has come to a complete stop. Switching it
off before the vehicle has stopped may im-
pair the function of the brake booster and
power steering. You would then need to use
more force to steer and brake the vehicle.
The fact that you cannot steer and brake as
usual may increase the risk of accidents and
serious
injuries.
— Never remove the ignition key from the igni-
tion lock while the vehicle is moving. Other-
wise, the steering lock could engage and you
would not be able to steer the vehicle, which
increases the risk of an accident.

@) Note
— Avoid high engine speed, full throttle, and
heavy engine load if the engine has not
reached operating temperature yet. You
could damage the engine.
— If the engine has been under heavy load for
an extended period of time, heat builds up
in the engine compartment after the engine
is switched off and there is a risk of damag-
ing the engine. For this reason, let the en-
gine run at idle for approximately two mi-
nutes before shutting it off.
@ Tips
— Brief noises are normal when starting and
stopping the vehicle and are no cause for
concern.
— For up to 10 minutes after stopping the en-
gine, the radiator fan may turn on again au-
tomatically or it may continue to run, even if
the ignition is switched off.
— It may not be possible to start the vehicle in
extremely low temperatures.

Z\ WARNING
Only use Launch Control when road and traffic
conditions allow it and other road users will
not be endangered or impacted by your driv-
ing and the vehicle's acceleration. The driving
wheels could spin and the vehicle could
swerve, especially on slick or slippery road
surfaces, which increases the risk of an acci-
dent.


CG) Note
When accelerating using Launch Control, all
vehicle components are subject to heavy
loads. This can result in increased wear.
G@) Tips
After accelerating using the Launch Control,
the temperature of some vehicle components

Drive system
A new vehicle must be broken in within the first
1,000 miles (1,500 km) so that all moving parts
work smoothly together, which helps to increase
the service life of the engine and other drive com-
ponents.
Do not drive higher than two-thirds of the maxi-
mum permitted engine RPM during the first 600
miles (1,000 km) and do not use full accelera-
78
tion. The engine can be increased RPM gradually
during the next 300 miles (S500 km).
Conventional drive system
Applies to: vehicles with conventional drive system
Vehicles with a conventional drive system are
powered by a combustion engine. It uses fuel to
recover energy.
ate RMN elec: me Lah)
Applies to: vehicles with plug-in hybrid drive
With plug-in hybrid drive, you can select between
the electric and combustion engine drive systems
or combine them > page 79, > page 76.
Coasting
Applies to: vehicles with coasting function
Similar to vehicles with a conventional drive sys-
tem, plug-in hybrid drive vehicles can also disen-
gage the combustion engine to save fuel. The ve-
hicle rolls without an engine braking effect in this
mode, which is “similar to coasting”. However,
the electric portion of the drive system remains
engaged and recuperates if necessary. You can
activate the coasting function in the “D” driving
program up to approximately 112 mph
(180 km/h). This occurs automatically when you
take your foot off the accelerator pedal.
Applies to: vehicles with plug-in hybrid drive
The vehicle is able to recover energy by using “re-
cuperation”. The electric drive system operates
like a generator and converts a large portion of
kinetic energy into electrical energy that is stored
in the high-voltage battery. The vehicle is braked
during recuperation, which is similar to the en-
gine braking effect on a vehicle with a combus-
tion engine. This will happen automatically when
you press the brake pedal while driving in “D”
gear, or when you remove your foot from the ac-
celerator pedal.
The energy recovery is displayed in the energy
flow display > page 80. The recuperation

Driving

— Turn off electrical equipment that is not need-
ed, for example seat heating*.
— Anticipate upcoming traffic situations while
driving to avoid unnecessary acceleration and
braking.
— Avoid driving at high speeds.
— Avoid adding extra weight to the vehicle if pos-
sible, for example by not leaving roof racks or
bike racks installed when they are not needed.
— Make sure the tire pressure is correct.
— Have maintenance performed regularly on the
vehicle.
— Do not drive with winter tires during the summ-
er.
— Do not let the engine run while the vehicle
parked.
— Use the Start/Stop system.
— Utilize the engine braking effect.
— Avoid driving short distances when possible.
— Plug-in hybrid drive: brake early and evenly to
use the recuperation function.
@) Tips
The amount of noise produced by the vehicle
can increase significantly when driving with a
sporty style. Show respect to others around
you and the environment with the way you op-
erate your vehicle, especially at night.
Energy management
Your vehicle is equipped with an intelligent ener-
gy management system for distributing electrici-
ty. This significantly improves the starting ability
and increases the vehicle battery life.
G) Tips
— If you drive short distances frequently, the
vehicle battery may not charge enough
while driving. As a result, convenience func-
tions for electrical equipment may be tem-
porarily unavailable.
— 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
82
electrical equipment will be limited or
switched off.
S Engine stopped: power steering and brake
booster not possible
There is a malfunction in the engine or the fuel
supply. More force is needed to steer and brake
the moving vehicle when the engine is stopped.
If the vehicle is rolling, try to bring it to a stop off
to the side from moving traffic. See an author-
ized Audi dealer or authorized Audi Service Facili-
ty for assistance.
EB EB Drive system: malfunction! Safely stop
vehicle
There is a malfunction in the plug-in hybrid sys-
tem. The brake booster and the power steering
may stop working. Stop the vehicle immediately
at a suitable location or as soon as possible. Park
the vehicle in a safe place outdoors that is not
near buildings, roof overhangs, carports or simi-
lar structures. Switch the ignition off. Have the
problem corrected by an authorized Audi dealer
or authorized Audi Service Facility.
B i B Electric drive: overheated! Safely stop
vehicle and check coolant
The coolant level is too Low or the coolant tem-
perature is too high. Stop the vehicle in the out-
doors as soon as it is safely possible. Switch the

ZA WARNING
If the engine stops while driving, you will
need to use more force to brake the vehicle.
This increases the risk of an accident. There
will still be power steering if the ignition is
switched on while the vehicle is rolling and
there is sufficient vehicle battery charge. Oth-
erwise, you must use greater force when
steering.

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 the vehicle is stopped, such as at
a traffic light. The ignition remains switched on
during this Stop phase. The engine will restart
automatically when needed.
The Start/Stop system is automatically activated
once the ignition is switched on.
Basic requirements for Start/Stop mode
— The driver's door must be closed.
— The driver's seat belt much be fastened.
— The hood must be closed.
— The vehicle must have driven faster than 2 mph
(3 km/h) since the last time it stopped.

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. If the
brake system becomes damp, for example after
driving in heavy rain, the braking effect may be
delayed. Other factors that could temporarily in-
crease the response time of the brakes include:
— Wet conditions
— Low temperatures, ice, and snow
— Roads covered in salt
— Dirty brake pads
To ensure the optimal braking effect, the brake
system is cleaned at regular intervals. This is
done by applying the brake pads to the brake ro-
tors for a short period of time when driving at
high speeds when the windshield wipers are
switched on.
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. This can
cause noises when braking as well as an uneven
braking effect. In this case, braking heavily sever-
al times while driving at high speeds can clean
the brake rotors > A\.
Brake pads
New brake pads do not achieve their full braking
effect during the first 250 miles (400 km). They
must be “broken in” first. However, you can com-
pensate for the slightly reduced braking force by
pressing firmly on the brake pedal. Avoid heavy
braking during the break-in period.
Brake pad wear depends largely on the way the
vehicle is driven and on operating conditions.
Brake pad wear increases when driving frequently
in the city or short distances or when using a very
sporty driving style. >

Driving


ZA WARNING
— Only apply the brakes for the purpose of
cleaning the brake system when road and
traffic conditions permit. You must not en-
danger other road users and increase the
risk of an accident.
— Due to the risk of injury, only have an au-
thorized Audi dealer or authorized Audi
Service Facility work on the brake system.
Incorrect repairs could impair the function.
— Never let the vehicle roll while the engine is
stopped because this increases the risk of an
accident.
— During automatic braking maneuvers, the
brake pedal may move downward automati-
cally. To reduce the risk of injury, do not

place your foot under the brake pedal.
@) Note
— Never let the brakes “rub” by pressing the
pedal lightly when braking is not actually
necessary. This can cause the brakes to over-
heat and increases braking distance and
causes wear.
— Observe the important information for driv-
ing downhill > page 89. This especially ap-
plies when towing a trailer.
@) Tips
— If you retrofit your vehicle with a front spoil-
er, wheel covers or similar items, make sure
that the air flow to the brakes is not ob-
structed. Otherwise the brake system can
overheat.

— Also refer to the information about brake
fluid > page 313.
