Selecting a gear
Requirement: the ignition must be switched on.
— Bring the vehicle to a full stop and press the
brake pedal.
— Press the release button @ on the selector lev-
er.
—To select the nearest gear, move the selector
lever forward or back until you feel the first
pressure point.
—To skip a gear (for example, move from “D” to
“R”), move the selector lever past the pressure
point in the desired direction.
— The label next to the selector lever for the se-
lected gear will light up.
“N” (Neutral) gear
In the “N” gear, power is not transmitted to the
driving wheels. Use the “N” gear in a car wash
(with conveyor belts), for example.
If you unintentionally select “N” while driving
(faster than 1 mph (2 km/h)), you can also shift
back to “D” without pressing the brake pedal.
For safety reasons, the vehicle cannot be locked
when the transmission is in the "N” gear.
“Pp” (Park) gear
Requirement: the ignition must be switched on.
The vehicle is secured from rolling away by the
parking lock when in the “P” gear.
— Bring the vehicle to a full stop and press the
brake pedal.
— Press the “P” button (2) on the selector lever.
— The “P” next to the selector lever will light up.
“P” engages automatically if you switch the en-
gine off while the “D” or “R” gear is selected. If
you switch the engine off in “N”, “P” will engage
automatically after approximately 30 minutes.
If you want to switch to another gear from “P”,
the engine must be running.
If you cannot shift out of “P”, for example be-
cause the vehicle has no power, you may need to
use the emergency release for the parking lock
=> page 112.

Selecting the driving program
Various driving programs can be selected when in
the “D” gear. The programs influence when the
transmission shifts and how the accelerator ped-
al responds.
The selected driving program is displayed in the
instrument cluster.
—D (Drive): normal driving mode
—S (Sport): sporty driving mode
If you select the Dynamic mode in Audi drive se-
lect*, the “S” driving program will be activated.
When the ignition is switched off, the driving pro-
gram may be reset to “D”.
To switch between the current driving program
and “S”, push the selector lever toward the rear.
Plug-in hybrid drive system: Not all plug-in hy-
brid modes are available in the “S” driving pro-
gram. The driving program or plug-in hybrid
mode will be automatically adjusted if it is not
compatible with an operation.
ZA\ WARNING
— Before you start driving, check if the label
for the desired selector lever position next
to the selector lever is lit up.
— Secure the vehicle against rolling before ex:
iting the vehicle > page 108.
— Power is still transmitted to the wheels
when the engine is running at idle. To pre-
vent the vehicle from “creeping”, you must
keep your foot on the brake in all selector
lever positions (except "P" and "N") when
the engine is running.
— To reduce the risk of an accident, do not
press the accelerator pedal when changing
gears if the vehicle is stationary and the en-
gine is running.
— Never select the “R" or "P” gears while driv-
ing. Doing so could cause an accident.
— The vehicle can roll even if the ignition is
switched off.
G) Tips
If you shift between “D” and “R” within one
second, you do not need to press the brake >

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)

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,
braking heavily several times while driving at
high speeds can clean the brake rotors > A\.
Applies to: vehicles with plug-in hybrid drive: Se-
lect the “N” gear so that recuperation is not used
for braking.
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.
Applies to: vehicles with plug-in hybrid drive: Be-
cause recuperation is also used for braking, the
break-in period for new brake pads is 500 miles
(800 km).
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.
Ceramic brakes
Applies to: vehicles with ceramic brakes
Ceramic brakes provide excellent deceleration
rates.
The break-in period for new ceramic brakes may
be significantly longer than for standard brake
rotors. Due to the properties of the material,
they may cause noises at lower speeds. Ceramic
brakes also absorb more moisture in wet condi-
tions. Therefore, there will temporarily be less
braking force than when the brakes are dry. You
can compensate for this by pressing the brake
pedal harder.
Automatic post-collision braking system
The automatic post-collision braking system can
help to reduce the risk of sliding and of addition-
al collisions after an accident. If the airbag con-
trol module detects a collision, the vehicle is
braked by the ESC.
The vehicle does not brake automatically if one of
the following occurs:
— The driver presses the accelerator pedal, or >
119
Page 122 of 362
Driving
— The braking force generated by the pressed
brake pedal is greater than the braking force
that
would be initiated by the system
— The ESC, the brake system, or the vehicle elec-
trical system is not functioning
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 122. This especially ap-
plies when towing a trailer.
G@) 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 283.
