Haptic feedback in the accelerator pedal indi-
cates when you should take your foot off the ac-
celerator pedal to drive more efficiently.
Combustion engine startup
Applies to: vehicles with plug-in hybrid drive
A haptic pressure point indicates when the com-
bustion engine will be started. The pressure point
is variable and depends on the high-voltage bat-
tery charge level.

Maximum acceleration
If you press the accelerator pedal all the way
down, the motor’s full power will be used and
you will reach maximum acceleration, also called
“kick-down”.
Applies to: vehicles with boost function: The elec-
tric motor can switch on for a brief period if the
accelerator pedal is pressed all the way down in
the “D” and “S” driving program. The availability
of this function depends on the charge level of
the high-voltage battery and the temperature of
the drive system components, among other
things.

ZA WARNING
The driving wheels could spin and the vehicle
could swerve on slick or slippery road surfaces
when using kick-down, which increases the
risk of an accident.

ZA WARNING
— The parking lock must be released using the
emergency release before towing the vehi-
cle.
— The parking lock may only be released using
the emergency release if the parking brake
is set. If it is not working, secure the vehicle
from rolling using the brake pedal or other
suitable means, such as blocking a front and
a rear wheel. An unsecured vehicle may roll
away, which increases the risk of an acci-


dent. >

Driving

The parking lock was released using the emer-
gency release > page 116 or can no longer be en-
gaged. Drive to an authorized Audi dealer or au-
thorized Audi Service Facility immediately to have
the malfunction corrected.
Move selector lever to automatic position
The transmission has switched out of tiptronic
mode. Switch back to automatic mode with the
selector lever > page 115.
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-
tion. The engine can be increased RPM gradually
during the next 300 miles (500 km).
Conventional and mild hybrid drive system
Applies to: vehicles with a conventional drive system or a mild
hybrid drive system
Vehicles with a conventional or mild hybrid drive
system are powered by a combustion engine. It
uses fuel to recover energy.
Vehicles with a mild hybrid drive system have ad-
ditional battery technology.
Plug-in hybrid drive
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 119, > page 115.
Coasting
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 like “coasting”. However, the elec-
118
tric portion of the drive system remains engaged
and recuperates if necessary. The coasting func-
tion can be automatically activated in the “D” or
“E” driving program. This occurs automatically
when you take your foot off the accelerator ped-
al.
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.
When you press the brake pedal, recuperation is
used to brake the vehicle. The brakes will only be
activated if necessary. When driving normally,
this makes it possible to brake using only recu-
peration just before coming to stop and to lose
little energy and range from braking.
Settings options
You can set if recuperation should be adjusted to
be proactive*, for example, to the road.
> Applies to: MMI: Select on the home screen:
VEHICLE > Charging & Efficiency > Efficiency
assist > Intelligent coasting.

Z\ WARNING
In certain situations, the recuperation may
brake proactively. However, the recuperation
braking effect is limited. Always be ready to
brake to reduce the risk of an accident.
G) Tips
If the ESC is limited or switched off, automat-
ic recuperation is not available and will not
brake.

Driving dynamic

With Road ahead: level correction, you can ad-
just how much the vehicle will compensate for
bumps in the road. For this purpose, there is a
camera behind the windshield that detects the
road conditions and activates the active suspen-
sion when bumps are predicted. A colored cone in
the display indicates when this function is acti-
vated. This function may only have limited availa-
bility under certain conditions, for example,
when it is dark > page 155.
Applies to: vehicles with elevated entry
With the Elevated entry function, you can select
if the vehicle should be raised when a door is
opened in order to enter and exit the vehicle
more comfortably. The vehicle will lower again
slowly in the following situations:
— When starting from a stop
— When locking the vehicle
— When changing the Audi drive select* mode
— Approximately 10 seconds after all doors have
been closed
— After a certain period of time when the engine
is stopped and a door is open, in order to main-
tain the battery charge level.
This function may not be available under certain
conditions, for example if the ground is not level
or when the battery charge level is low. The func-
tion may also be deactivated temporarily after
the
vehicle is serviced using diagnostic equip-
ment, and it will only be available again once the
vehicle is driven a certain distance.
©) Note
When the elevated entry function is activated,
make sure there is sufficient space above and
below the vehicle. This particularly applies to
space under open doors and above roof struc-
tures. If you are unsure about the amount of
space, deactivate the elevated entry function
before exiting the vehicle to reduce the risk of
damage.
@ Tips
— If an open door touches the ground or be-
comes stuck, use the Raise > page 129
130
function in the MMI to raise the vehicle us-
ing the air suspension.
— When the curve tilting function is switched
on, the vehicle passengers will experience
less turning force when driving around
curves. This may influence the perception of
speed. Always adjust the speed to the driv-
ing situation.
Ground clearance
The vehicle height and clearance can be influ-
enced by the following factors:
— Change in temperature
— Change in load
— Change to the Audi drive select* mode
— Lifting and lowering via the air suspension*
— Automatic lifting and lowering using the Ele-
vated entry* function

ZA\ WARNING
To reduce the risk of injury, make sure no one
gets pinched when the vehicle level is chang-
ing, for example when cleaning the under-
body or the wheel housings.
C) Note
Always make sure there is enough clearance
above and below the vehicle. This is especially
important for entrances with height restric-
tions, for example, before driving into under-
ground garages. You could also scrape the
ground when driving over the edges of curbs
or on steep ramps, which could damage your
vehicle.

Steering
Electromechanical steering supports the driver's
steering movements by electronically adapting
the power steering depending on the vehicle
speed. The settings depend on the selected Audi
drive select* mode.
Dynamic all-wheel steering
Applies to: vehicles with dynamic all-wheel steering
Active corrective steering at the front and rear
axles increases the driving dynamic and driving
stability. At low speeds, the rear wheels are
steered in the opposite direction from the front
wheels to reduce the steering effort needed by
the driver and to reduce the turning radius. Vehi-
cle handling improves. At high speeds, steering
the rear wheels in the same direction as the front
wheels improves the vehicle response and driving
stability. The vehicle reacts quickly and precisely
to the driver's steering movements.
a Steering: malfunction! Please stop vehicle
The power steering may have failed. Adapt your
driving style immediately to compensate for the
fact that it may be more difficult to turn the
steering wheel, and stop your vehicle in a safe lo-

tion in the electronic steering lock because
this increases the risk of an accident.
@ Tips
— If there is a malfunction, the steering wheel
may be crooked when driving straight.
—Ifthe a or a indicator light only stays on
for a short time, you may continue driving.


ALL wheel drive (quattro)
Applies to: vehicles with all wheel drive
The all-wheel drive system distributes the driving
power variably to the front and rear axle to im-
prove the driving characteristics. It works togeth-
er with selective wheel torque control, which can
activate when driving through curves
> page 134.
The all-wheel drive system is designed for high
engine power. Your vehicle is exceptionally pow-
erful and has excellent driving characteristics
both under normal driving conditions and on
snow and ice. Always read and follow safety pre-
cautions > A\.

Z\ WARNING
— Even in vehicles with all wheel drive, you
should adapt your driving style to the cur-
rent road and traffic conditions to reduce
the risk of an accident.
— The braking ability of your vehicle is limited
to the traction of the wheels. In this way, it
is not different from a two wheel drive vehi-
cle. Do not drive too fast because this in-
creases the risk of an accident.
— Note that on wet streets, the front wheels
can “hydroplane” if driving at speeds that >

are too high. Unlike front wheel drive
vehicles, the engine RPM does not increase
suddenly when the vehicle begins hydro-
planing. Adapt your speed to the road condi-
tions to reduce the risk of an accident.
Sy Telamelaielcls
Applies to: vehicles with sport differential

The sport differential distributes the drive power
to the rear axle based on the situation. The goal
is a high level of agility and ability to accelerate
on curves. The vehicle is very responsive to steer-
ing. The settings depend on the selected Audi
drive select* mode.
Messages
Hi Sport differential: malfunction! Please con-
tact Service
Drive immediately to an authorized Audi dealer
or authorized Audi Service Facility to have the
malfunction repaired.
it} Sport differential: temperature too high.
Please adapt driving style
The transmission temperature has increased sig-
nificantly due to the sporty driving manner. Drive
in a less sporty manner until the temperature re-
turns to the normal range and the indicator light
switches of.

Z\ WARNING
Contact an authorized Audi dealer or author-
ized Audi Service Facility if the sport differen-
tial is faulty or malfunctioning. The repair
must be performed by trained personnel us-
ing the correct oil in order to ensure safety.

Electronic Stabilization
Control
Electronic Stabilization Control (ESC) supports
driver safety. It reduces the risk of slipping and
improves driving stability. ESC detects critical sit-
uations, such as if the vehicle is oversteering or
understeering, or if the wheels are spinning. The
brakes are applied or the engine torque is re-
duced in order to stabilize the vehicle.
If the [i indicator light blinks while driving, the
ESC is actively regulating.
If the B&B indicator light turns on, the system has
switched the ESC off. In this case, you can switch
the ignition off and then on to switch the ESC on
again. The indicator light turns off when the sys-
tem is fully functional.
If the B indicator light turns on, ESC was limit-
ed or switched off manually > page 134.
The following systems are integrated in the ESC:
Anti-lock braking system (ABS)
ABS prevents the wheels from locking when brak-
ing. The vehicle can still be steered even during
hard braking. Apply steady pressure to the brake
pedal. Do not pump the pedal.
A pulsing in the brake pedal indicates that the
system is acting to stabilize the vehicle.
Brake assist
The brake assist system can decrease braking dis-
tance. It increases braking power when the driver
presses the brake pedal quickly in emergency sit-
uations. You must press and hold the brake pedal
until the dangerous situation is over. Depending
on the activated driver assistance systems, the
brake assist system may react with increased sen-
sitivity.
Anti-Slip Regulation (ASR)
ASR reduces drive power when the wheels begin
spinning and adapts the power to the road condi-
tions. This will increase the driving stability.
Electronic Differential Lock (EDL)
The EDL applies the brakes to wheels that are
slipping and transfers the drive power to the oth-
er wheels. This function is not available at higher
speeds.
In extreme cases, EDL automatically switches off
to keep the brake on the braked wheel from over-
heating. The vehicle is still functioning correctly. >
