Driving
lead to greater tire wear and will affect driving
behavior.
Do not drive on
winter tires year-round, as this
will consume up to 10% more fuel.
Eliminate unnecessary weight
Since every kilogram of extra
weight increases
fuel consumption, a quick inspection of the lug­
gage compartment may be worth it to avoid un­
necessary weight.
When not being used, a roof rack should be re­ moved to decrease the wind resistance of the ve­
hicle. You will save approximately 12% of your
fuel when at speeds from 62- 7 5 mph (100-120 km/h) .
Save energy
The engine drives the generator, which generates
electricity; the fuel consumption also increases
with the demand for electricity. Therefore, switch electrical equipment off when you no longer
need it. Examples of equipment that uses a lot of
energy are air blowers at a high setting, the rear
window defogger and seat heating*.
CD Note
Do not leave engine idling unattended after
starting.
If warning lights should come on to
indicate improper operation, they would go
unheeded. Extended idling also produces
heat, which could result in overheating or
other damage to the vehicle or other proper­
ty .
CD Note
- Have your vehicle maintained properly and
in accordance with the service recommenda­
tions in your Warranty
& Maintenance book ­
let . Lack of proper maintenance as well as
improper use of the vehicle will impair the
function of the emission control system and
could lead to damage.
- Do not alter or
remove any component of
the Emission Control System unless ap­
proved by the manufacturer.
- Do not alter or remove any device, such as
heat shields, switches, ignition wires,
68
valves, which are designed to protect your
vehicle's Emission Control System and other
important vehicle components.
(D Tips
The consumption estimates as published by
ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the
road, which will vary depending upon vehicle
load and speed, road and weather conditions,
trip length, etc.

open the driver's door. The locked steering helps
prevent vehicle theft.
Emergency off function*
If it is absolutely necessary, the engine can also
be turned off while driving in the R or D/S selec­
tor lever position at speeds below 6 mph (10 km/
h). To stop the engine, press and hold the
I START ENGINE STOPI button and also press the
brake pedal.
~ WARNING
- Never turn off the engine before the vehicle
has come to a complete stop. The full func­
tion of the brake booster and the power
steering is not guaranteed. You may need to
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.
- Always take the key with you whenever you
leave your vehicle. Otherwise, the engine
could be started or electrical equipment
such as the power windows could be operat­
ed. This can lead to serious injury.
- For safety reasons, always park the vehicle
with the selector lever in the P position.
Otherwise, there is the risk that the vehicle
could roll unintentionally.
(D Note
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 damaging
the engine. For this reason, let the engine run

at idle for approximately two minutes before
shutting it off.
(D Tips
After the engine has been switched off, the
radiator fan can continue to run for up to 10
minutes -even with the ignition switched off.
It can also switch on again after some time if
the coolant temperature rises as the result of
heat buildup or if the engine is already warm
and the engine compartment is also heated
by the sun's rays.

Driving
During emergency braking, your vehicle will
brake similar to heavy braking. ESC and the
associated components (ABS, ASR, EDL)
cannot overcome the laws of physics. In cor­
ners and when road or weather conditions
are bad, a full brake application can cause
the vehicle to skid or the rear end to swerve,
which increases the risk of an accident.
- If the power supply fails, you cannot set the
parking brake if it is released. In this case,
park the vehicle on level ground and secure
it by placing the selector lever in the P posi­
tion. See an authorized Audi dealer or au­
thorized Audi Service Facility for assistance.
- Always take the vehicle key with you when leaving your vehicle, even for a short period
of time. This applies particularly when chil­
dren remain in the vehicle . Otherwise chil­
dren could start the engine, release the
parking brake or operate electrical equip­
ment such as power windows, which in­
creases the risk of an accident.
- No one should remain in the vehicle when it is locked -especially children. Locked doors
make it more difficult for emergency work­
ers to get into the vehicle, which puts lives
at risk.
(D Tips
When stopping at a traffic signal or stopping in city traffic, you can set the parking brake
manually. The vehicle does not have to be
held with the brake pedal. The parking brake
eliminates the tendency to creep when a se­
lector lever position is engaged. As soon as
you press the accelerator pedal, the parking brake releases automatically and your vehicle
starts to move ¢
page 76.
(D} Tips
-Occasional noises when the parking brake is
set and released are normal and are not a
cause for concern.
- The parking brake goes through a self-test
cycle at regular intervals when the vehicle is
stopped. Any noises associated with this are normal.
76
- If there is a power failure, the parking brake
will not set if it is released, and it will not release if it is set ¢&. . See an authorized
Audi dealer or authorized Audi Service Fa­ cility for assistance .
Starting from a stop
Various convenience and safety functions may be
available when the vehicle begins driving, de­
pending on vehicle equipment .
Starting on hills with the parking brake set
Requirement: the driver's door must be closed
and the driver's safety belt must be fastened.
.,. To start driving comfortably when on a hill, set
the parking brake and begin driving as usual.
The braking force of the parking brake does not
release automatically until the wheels build up
enough driving force.
Starting on hills with hill hold assist
Hill hold assist makes it easier to start on hills.
Requirement: the driver's door must be closed
and the engine must be running.
.,. To activate hill hold assist, press and hold the
brake pedal for several seconds. The vehicle
must be in an uphill direction of travel.
After releasing the brake pedal, the braking pow­ er is maintained for a brief moment¢&. to pre ­
vent the vehicle from rolling back when starting.
During this time, you can easily begin to move
your vehicle.
&_ WARNING
- If you do not begin driving immediately or
the engine stalls after releasing the brake
pedal, your vehicle may begin to roll back-
ward. Press the brake pedal or set the park- ing brake immediately.
- The intelligent technology of hill hold assist
cannot overcome the limitations imposed by
natural physical laws. The increased comfort
offered by hill hold assist should not cause
.
you to take safety risks . ~

A WARNING
-Always pay attention to traffic and to the
area around your vehicle. Side assist cannot
replace a driver's attention. The driver alone
is always responsible for lane changes and
similar driving maneuvers.
- In some situations, the system may not
function or its function may be limited. For
example:
- If vehicles are approaching or being left
behind very quickly. The display may not
turn on in time.
- In poor weather conditions such as heavy
rain, snow or heavy mist.
- On very wide lanes, in tight curves, or if
there is a rise in the road surface. Vehicles
in the adjacent lane may not be detected
because they are outside of the sensor
range.
- Audi side assist cannot detect all vehicles under all conditions, which can increase the
risk of accidents.
- Please note that side assist only displays ap­ proaching vehicles or vehicles in your blind
spot if your vehicle is traveling at least
19 mph (30 km/h).
- In certain situations, the system may not
work or its function may be limited. For ex­
ample:
- The display may not turn on at the right

" N .... 0 0 <..:l ' The energy management system Is made up of
battery diagno sis , idling current management ,
and dynamic energy management.
Battery diagnosis
The batte ry diagnosis determines the vehicle bat ­
tery charge level. The sensors detect the battery,
the battery current, and the battery temperature.
The current charge leve l and the performance of
the vehicle battery are determined based on this.
Idling current management
The idl ing current management decreases the
energy used whi le pa rked . With the engine
switched off, it manages the energy distribution
to the different electrical components . Data from
the battery diagnosis is taken into account for
this.
Depending on the vehicle battery charge level,
e lectrical equipment is switched off one item af­
ter the other to prevent the vehicle battery from
draining and to maintain the starting ability.
Dynamic energy management
While driving, dynamic energy management dis ­
tributes the appropriate amount of energy to the
e lectrical equipment. It controls the battery
charge level so that the amount of energy is not
greater than the amount being generated in or­
der to mainta in an optimal veh icle battery charge
level.
(D Tips
- Energy management cannot overcome the
laws of physics . Note that the charge level
and length of the vehicle battery life are
limited.
- When the start ing ability is endangered, the
(•) indicator light turns on
~ page 14.
What you should know
Maintaining the starting ability is the highest
priority.
A lot of stress is placed on the vehicle battery
when dr iving short distances, during c ity dr iving,
and at cold times of the year . A lot of energy is
Intelligent Technology
u sed but little is generated. It is also critical
when the engine is not running but electrical
equipment is switched on. In this case, energy is
used but none is generated.
In situations like this, energy management wi ll
active ly regulate the distribution of energy .
Long periods without use
If you do not drive your vehicle for severa l days or
weeks, electrical equ ipment is gradually scaled
back or switched off. This reduces energy use and
ensures the vehicle will be able to start after long
periods of time . Some convenience functions,
s u ch as interior lighting or power seat ad just­
ment, may not be ava ilable under certain circum­
stances. These conven ience functions will be
available again once you switch the ignition on
and start the engine.
With the engine switched off
The vehicle battery will dra in if you use Infotain ­
ment functions such as listening to the radio
whi le the engine is switched off .
T he vehicle's ability to start may be impaired by
the energy use, a message will appear in the In­
fotainment system display.
The message indicates that the system wi ll
switch off automatically soon. If you would like
to continue using the functions, you must start
the engine.
With the engine running
Although e lectr ica l ene rgy is generated while
driving , the vehicle battery can drain. This can
happen if litt le energy is generated but much is
used, and the charge level of the vehicle battery
is not optimal.
To restore the balance of energy, components
that require large amounts of energy are tempo­ rarily scaled back or sw itched off. Heat ing sys­
tems in particular requ ire a great deal of energy.
If you notice, for example, that the seat heating*
or rear window defogger is not work ing, then it
has been tempora rily reduced or sw itched off.
Th ese systems are available again as soon as the
energy supply has been restored. .,.
