Driving

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.

Electromechanical
parking brake
The ©) switch is located under the selector lever
in the center console.
Your vehicle is equipped with an electromechani-
cal parking brake. The parking brake is designed
to prevent the vehicle from rolling unintentional-
ly and replaces the hand brake.
Setting/manually releasing the parking
brake
> Pull the @) switch to set the parking brake. The
LED in the switch turns on. The Zw (USA mod-
els)/[@) (Canada models) indicator light also
turns on in the instrument cluster display.
> To release the parking brake manually, press
the brake or accelerator pedal while the igni-
tion is switched on and press the ©) switch at
the same time. The LED in the button and the
indicator light in the display turn off.
Releasing the parking brake automatically
Requirement: The driver's door must be closed.
> To start driving and release the parking brake
automatically, press the accelerator pedal as
usual.
In addition to releasing the parking brake auto-
matically, other convenience and safety functions
are available when you start driving > page 66,
Starting to drive.
Emergency braking function
You can use the emergency braking function in an
emergency situation, or if the standard brakes
are malfunctioning or the pedal is obstructed.
> Pull and hold the ©) switch.
>» As soon as you release the (©) switch or acceler-
ate, the braking stops.
Pulling and holding the ©) switch while driving
the vehicle activates the emergency braking func-
tion. The hydraulic brake system will brake all
four wheels. The braking effect is similar to heavy
braking > A\.
To reduce the risk of activating the emergency
braking by mistake, a warning tone (buzzer)
sounds when the ©) switch is pulled. Emergency
braking stops as soon as the ©) switch is released
or the accelerator pedal is pressed.
Parking
> Press the brake pedal to stop the vehicle.
> Pull the ©) switch to set the parking brake.
> Select the "P" selector lever position.
> Turn the engine off > /\.
> Turn the steering wheel when parking on in-
clines so that the wheels will roll into the curb
if the vehicle starts moving.

ZA WARNING
— If a gear is engaged while the vehicle is sta-
tionary and the engine is running, do not
press the accelerator pedal inadvertently.
Otherwise, the vehicle will start to move im-
mediately and this could result in an acci-
dent.
— Emergency braking should only be used in
an emergency, when the when the standard
brake pedal is malfunctioning or obstructed.
During emergency braking, your vehicle will
brake similar to heavy braking. ESC and the
associated components (ABS, ASR, EDL) can-
not overcome the laws of physics. In corners
and when road or weather conditions are
bad, a full brake application can cause the

Driving


— 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.
Switching the system on
