Driving
General information
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.
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).
Reducing the risk of vehicle damage
@ Note
When driving on poor roads, over curbs, and
on steep ramps, make sure that components
that hang below the vehicle, such as the spoil-
er and exhaust system, are not struck because
they could be damaged. This especially ap-
plies to vehicles with low ground clearance
and vehicles that are heavily loaded.
Driving through water on roads
Note the following to reduce the risk of vehicle
damage when driving through water, for example
on flooded roads:
— The water must not be any higher than the bot-
tom of the vehicle body.
— Do not drive faster than walking speed.

ZA WARNING
After driving through water or mud, the effec-
tiveness of the brakes may be reduced due to
moisture on the brake rotors and brake pads.
A few careful brake applications should dry off
the brakes and restore the full braking effect.


@) Note
— Vehicle components such as the engine,
transmission, suspension, or electrical sys-
tem, can be severely damaged by driving
through water.
— Always switch the Start/Stop system* off
when driving through water > page 62.
@) Tips
— Determine the depth before driving through
water.
— Do not stop the vehicle, drive in reverse, or
switch the engine off when driving through
water.
— Keep in mind that oncoming vehicles may
create waves that raise the water level and
make it too deep for your vehicle to drive
through safely.
— Avoid driving through salt water, because
this can cause corrosion.

driving
The amount of fuel consumption, the environ-
mental impact, and the wear to the engine,
brakes, and tires depends mostly on your driving
style. Note the following information for efficient
and environmentally-conscious driving:
— Do not let the engine run while the vehicle
parked.
— Use the Start/Stop system > page 62.
— 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.
— Utilize the engine braking effect.
— Avoid driving short distances or at high speeds
when possible.
— 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.
— Have maintenance performed regularly on the
vehicle.
— Do not drive with winter tires during the summ-
er.
— Make sure the tire pressure is correct
=> page 254.

— Hill hold assist cannot hold the vehicle in
place on all hills (for example, if the ground
is slippery or icy).
—To reduce the risk of an accident, always
make sure the vehicle is situated safely
while stationary.

Sporty driving
When driving in a sporty style, for example ona
driving track, the wear on all vehicle components
is greatly increased, especially on the engine,
transmission, tires, brakes, and suspension. This
can result in increased wear. Also note the fol-
lowing points:
— Make sure the vehicle is in good condition.
Make sure to check the brake pads, tire tread,
and tire pressure (when tires are warm).
— Beforehand, warm up the engine by driving no
higher than two-thirds of the maximum permit-
ted engine RPM. The engine oil temperature
must be brought to a minimum of 140 °F
(60 °C).
— Before stopping the vehicle, allow the engine
and brakes to cool back down to a regular oper-
ating temperature by driving normally.
If necessary, use the following functions:
— Audi drive select* Dynamic mode > page 78
— Launch Control > page 70
— Limit ESC > page 87
@) Tips
Wear caused by load does not constitute a ve-
hicle fault as defined by the terms of the war-
ranty.
Automatic transmission
Introduction
Your vehicle is equipped with an electronically-
controlled DSG transmission called S tronic. Two
independent clutches transfer the power be-
tween the engine and transmission. It allows the
vehicle to accelerate without a noticeable inter-
ruption in traction.
The transmission shifts up or down automatically
depending on which drive program is selected.
When a moderate driving style is used, the
transmission selects the most economical driving
mode. The transmission upshifts at a lower RPM
and downshifts at a higher RPM to improve fuel
efficiency.
If desired, the driver can also select the gears
manually (tiptronic mode) > page 71.
Selecting a selector lever position

Fig. 73 Selector lever
The current selector lever position is shown next
to the selector lever > fig. 73. The current selec-
tor lever position is also shown in the instrument
cluster display.
> You may need to release the selector lever lock
depending on which selector lever position is
selected and which one you would like to select.
> To do this, press the release button @ on the
selector lever > fig. 73.
> To engage the nearest selector lever position,
move the selector lever forward or back until
you feel the first pressure point. The selector
lever will return to its original position.
> To shift beyond the nearest selector lever posi-
tion, move the selector lever past the pressure
point into the desired position. The selector lev-
er will return to its original position.
For example, you can skip over the "N" position if
you would like to go directly from "D" into "R".
Selector lever lock
The selector lever lock reduces the risk of select-
ing a position unintentionally, which can cause
the vehicle to roll. When engaging some selector >

Assist systems

Assist systems
Speed warning system
Applies to: vehicles with speed warning system
The speed warning system helps you to stay be-
low a specified maximum speed that can be set,
changed or deleted in the Infotainment system.
The speed warning system warns you if you are
exceeding the maximum speed that you have set.
A warning tone will sound as soon as your speed
exceeds the stored value slightly. The ow in-
dicator light and a message will appear in the in-
strument cluster display at the same time. The
bbe) indicator light and the message turn off if
the speed falls back below the stored maximum
speed.
Setting a threshold is recommended if you would
like to be reminded when you reach a certain
maximum speed. Situations where you may want
to do so include driving in a country with a gener-
al speed limit or if there is a specified maximum
speed for winter tires.
Setting the warning threshold

> Select in the Infotainment system: [MENU] but-
ton > Vehicle > left control button > Driver as-
sistance > Speed warning > Manual.
G) Tips
Regardless of the speed warning system, you
should always monitor your speed using the
speedometer and make sure you are following
the legal speed limit.

Cruise control system
Applies to: vehicles with cruise control system
The cruise control system assists the driver in
maintaining a constant speed above approxi-
mately 15 mph (20 km/h). The system maintains
the desired speed by braking and accelerating.
74

Z\ WARNING
— Always pay attention to the traffic around
your vehicle when the cruise control system
is in operation. As the driver, you are always
responsible for controlling your vehicle
speed and the distance between your vehicle
and
other vehicles.
— For safety reasons, cruise control should not
be used in the city, in stop-and-go traffic, on
winding roads, and when road conditions are
poor (such as ice, fog, gravel, heavy rain,
and conditions that could lead to hydroplan-
ing), because this increases the risk of an ac-
cident.
— Switch the cruise control off temporarily
when driving in turning lanes, highway exits,
or in construction zones.
—To reduce the risk of an accident, you should
only resume the stored speed if it is suitable
for the current traffic conditions.
() Note
Before driving downhill a long distance on a
steep hill, decrease your speed and select a
lower gear. This makes use of the engine brak-
ing effect and reduces the load placed on the
brakes.
G) Tips
The brake lights turn on when the brakes are
applied automatically.

snow and ice. Always read and follow safety pre-
cautions > A\.
Winter tires
By using all wheel drive, your vehicle has good
forward motion with standard tires in winter con-
ditions. However, in winter we recommend using
winter or all season tires on all four wheels, be-
cause this will improve the braking effect.
Snow chains
If there are snow chain laws, snow chains must
also be used on vehicles with all wheel drive
= page 259, Snow chains.

ZA WARNING
— Also, in vehicles with all wheel drive, adapt
your driving style to the current road and
traffic conditions. Do not let the increased
safety provided tempt you into taking risks,
because this increases the risk of an acci-
dent.
— 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 be tempted to accelerate toa
high speed when the road is slippery, be-
cause this increases 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 vehi-
cles, the engine RPM does not increase sud-
denly when the vehicle begins hydroplaning.
For this reason, adapt your speed to the
road conditions to reduce the risk of an acci-
dent.

Rear spoiler
Applies to: vehicles with retractable rear spoiler
The extendable rear spoiler increases driving sta-
bility.

Fig. 92 Center console: button for the rear spoiler
The rear spoiler retracts and extends. It can be
activated in various operating modes (manual
mode or automatic mode).
Automatic mode (normal operation)
— Automatic extension: this occurs when driving
faster than approximately 75 mph (120 km/h)
or at a certain engine compartment tempera-
ture.
— Automatic retraction: this occurs when driving
slower than approximately 22 mph (35 km/h)
or at a certain engine compartment tempera-
ture.
Manual mode
— Extending manually: briefly tap the > fig. 92
button to fully extend the rear spoiler.
— Retracting manually: when driving at speeds
below approximately 10 mph (20 km/h), press
and hold the button to retract the rear spoiler.
At speeds between 10 mph (20 km/h) and 62
mph (100 km/h), the rear spoiler will com-
pletely retract when you tap the button. You
cannot retract the rear spoiler if it extended
due to the engine compartment temperature.

tact Service
The rear spoiler may not have extended due toa
malfunction. This could change the vehicle's driv-
ing characteristics at high speeds. Do not drive >

and Tires
General information
> Check your tires regularly for
damage, such as punctures,
cuts, cracks, and bulges. Remove
foreign objects from the tire
tread.
>If driving over curbs or similar
obstacles, drive slowly and ap-
proach the curb at an angle.
> Have faulty tires or rims re-
placed immediately.
>Protect your tires from oil,
grease, and fuel.
>Mark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled.
>Lay tires flat when storing and
store them ina cool, dry location
with as little exposure to light as
possible.

J WARNING
—Never drive faster than the
maximum permitted speed for
your tires. This could cause the
tires to heat up too much. This
increases the risk of an acci-
dent because it can cause the
tire to burst.

244


—Always adapt your driving to
the road and traffic condi-
tions. Drive carefully and re-
duce your speed on icy or slip-
pery roads. Even winter tires
can lose traction on black ice.

() Note
—Please note that summer and
winter tires are designed for
the conditions that are typical
in those seasons. Audi recom-
mends using winter tires dur-
ing the winter months. Low
temperatures significantly de-
crease the elasticity of summ-
er tires, which affects traction
and braking ability. If summer
tires are used in very cold tem-
peratures, cracks can form on
the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
—Burnished, polished or
chromed rims must not be
used in winter driving condi-
tions. The surface of the rims
does not have sufficient corro-
sion protection for this and
could be permanently dam-
aged by road salt or similar
substances.
