Driving


— If the engine must run while you are working
in the engine compartment with the hood
open, make sure a gear is not engaged. The
selector lever must be firmly in the P posi-
tion and locked in place and the parking
brake must be set > page 200. Otherwise,
the vehicle could begin moving when in-
creasing the engine speed, even with the

parking brake set.

() Note
— If you have to stop on an incline, always
press the brake pedal to hold the vehicle in
place to reduce the risk of the vehicle rolling
backward. Do not try to hold the vehicle in
place by pressing and holding the accelera-
tor pedal. The transmission can overheat,
which increases the risk of damage.
— Allowing the vehicle to roll when the engine
is stopped and the selector lever is in the N
position will damage the automatic trans-
mission because it is not lubricated under
those circumstances.
— The transmission can overheat and be dam-
aged under certain driving and traffic condi-
tions such as frequent starts, creeping fora
long time, or stop-and-go traffic. When the
i or os] indicator light turns on, stop the
vehicle at the next opportunity and let the
transmission cool > page 87.
— Allowing the vehicle to roll when the engine
is stopped will damage the S tronic trans-
mission because it is not lubricated
= page 250, Towing.
@® Tips
For safety reasons, the parking brake is re-
leased automatically only when the driver's
safety belt is fastened.
Hill descent control
The hill descent control system assists the driver
when driving down hills.
Hill descent control is activated when the selec-
tor lever is in the "D" or "S" position and you
press the brake pedal. The transmission auto-

matically selects a gear that is suitable for the
hill. Hill descent control tries to maintain the
speed that was selected at the time of braking,
within physical and technical limitations. If may
still be necessary to adjust the speed with the
brakes. Because hill descent control cannot shift
down farther than 3rd gear, it may be necessary
to shift into tiptronic mode in very steep areas. In
this case, shift manually into 1st or 2nd gear in
tiptronic mode to use the engine's braking force
to relieve the brakes.
Hill descent control switches off once the hill lev-
els
out or if you press the accelerator pedal.
On vehicles with a cruise control system*
= page 89, hill descent control is also activated
when the speed is set.

ZA\ WARNING
Hill descent control may not be able to main-
tain a constant speed under all conditions. Al-
ways be ready to apply the brakes.
Shifting manually (tiptronic mode)
The tiptronic mode allows the driver to shift the
gears manually.

Driving

You can shift the gears manually when in “D”
mode. The transmission must be in tiptronic
mode.
Shifting with the selector lever
You can shift into manual shifting mode while the
vehicle is stationary or while driving.
> To switch to manual shifting mode, tilt the se-
lector lever toward the front passenger's side
> fig. 90. “M” will be displayed in the instru-
ment cluster.
> Upshifting: push the selector lever forward G).

lector lever toward the driver's side.
Shifting with the shift paddles
Applies to: vehicles with shift paddles
> Upshifting: press the @) shift paddle © fig. 97.
> Downshifting: press the ©) shift paddle.
» Applies to: RS models: To select the lowest/
highest possible gear, press and hold the shift
paddle @)/@).
If the shift paddles are tapped while in the D/S
selector lever position, automatic mode switches
off briefly. To switch from manually shifting back
to automatic shifting immediately, tap the shift
paddle @) © fig. 97 for 1 second.
To keep shifting manually, tilt the selector lever
toward the front passenger's side.
@ Tips
— The transmission only allows manual shift-
ing when the engine speed is within the per-
mitted range.
— The transmission automatically shifts up or
down before critical engine speed is
reached.
— Applies to: RS models: When accelerating,
the transmission will not automatically shift
to the next gear shortly before the maxi-
mum permitted engine RPM is reached.
Shift to the next highest gear at the right
time.
86
Kick-down enables maximum acceleration.
When you press the accelerator pedal down be-
yond the resistance point, the automatic trans-
mission downshifts into a lower gear and the en-
gine utilizes its full power, if the vehicle speed
and engine RPM permit. It shifts up into the next
higher gear once the maximum permitted engine
RPM is reached.

ZA\ WARNING
Please note that the wheels could spin on
slick or slippery roads when kick-down is ac-
tive.
Launch Control
Applies to: vehicles with Launch Control

Launch Control provides the best possible accel-
eration when starting from a stop.
Requirements
— The engine must be at operating temperature.
— The steering wheel must not be turned.
— Start/Stop system* must be deactivated

Audi drive select (drive
settings)
Introduction
Applies to: vehicles with Audi drive select
Drive select makes it possible to experience dif-
ferent types of vehicle characteristics in one vehi-
cle. With different driving modes, the driver can
switch the setting, for example from sporty to
comfortable. In the Individual mode, the set-
tings can be adjusted to your personal preferen-
ces. This makes it possible to combine settings
such as a sporty drivetrain setting with comforta-
ble steering.


Using Audi drive select incorrectly can lead to
collisions, other accidents and serious inju-
ries.

Applies to: vehicles with Audi drive select

The vehicle setup in each mode depends on the
vehicle's features.
Engine and automatic transmission
Depending on the mode, the engine and auto-
matic transmission respond more quickly or ina
more balanced manner to accelerator pedal
movements.
Suspension control (Audi magnetic ride)*
The suspension control uses sensors to record in-
formation regarding steering movements, brak-
ing and acceleration operations by the driver, as
well as information about the road surface, driv-
ing speed, and load. With drive select, you can
adjust the suspension control to sporty (dynam-
ic), comfortable (comfort) or balanced (auto).
96

Steering
The power steering adapts. Indirect steering that
moves easily as in comfort mode is especially
suited to long drives on a highway. The dynamic
mode provides sporty, direct steering.
Engine sound*
The engine sound adapts to the current mode
and can be subtle to sporty.


— Certain vehicle settings will be reset when
the ignition is switched off.
— In some models, the maximum vehicle
speed can only be reached in the auto and
dynamic modes.
Selecting the driving mode
Applies to: vehicles with Audi drive select
You can choose between comfort, auto, dynamic
and individual.

Emergency assistance

4. Attach the other end of the negative cable
(black) to the jump start connection @ on
the vehicle.
Starting the engine
> Start the engine in the vehicle giving the charge
and let it run at idle.
> Now start the engine in your vehicle, which has
the
drained battery.
> If the engine does not start, stop the starting
procedure after 10 seconds and then repeat it
after approximately 30 seconds.
> Turn on the rear window defogger in your vehi-
cle in order to reduce any voltage peaks that
may occur when disconnecting the jump start
cables. The headlights must be switched off.
> With the engines running, remove the cables in
reverse order of the way they were installed.
> Close the red cover on the positive terminal.

ZA\ WARNING
— Never connect the jump start cable directly
to your vehicle battery. Only use the connec-
tions in the engine compartment.
— Do not touch the non-insulated parts of the
terminal clamps. The cable must also not
come into contact with vehicle components
that conduct electricity when it is connected
to the positive vehicle battery terminal. This
can cause a short circuit.
— The locking bolts on the battery cells must
be tightened securely.
— Keep ignition sources (open flames, burning
cigarettes, etc.) away from the vehicle bat-
teries to reduce the risk of an explosion.
— Route the jump start cables so they cannot
get caught in the moving parts in the other

vehicle's engine compartment.

C) Note
Please note that the connecting process previ-
ously described for the jump start cables is in-
tended for when your vehicle is being jump
started.
250
G) Tips
Make sure that the connected jump start ca-
bles have sufficient contact with metal.
Towing
General information
You should only perform the steps that follow if
you have the necessary tools and technical ex-
pertise.
Towing requires a certain amount of practice.
Audi recommends contacting a towing company
to have the vehicle transported.
You should only have your vehicle towed by an-
other vehicle when disabled in exceptional cir-
cumstances. Inexperienced drivers should not
tow.
Notes on towing
When the engine is stopped, the transmission
will not be sufficiently lubricated if traveling at
high speeds and long distances:
— The maximum permitted towing speed is 30
mph (50 km/h).
— The maximum permitted towing distance is 30
miles (SO km).
Additional information on towing with a tow
truck
The vehicle may only be towed with the front axle
raised. Do not wrap any chains or cables around
the brake lines.
If the vehicle should be towed with the axle
raised, then the ignition must be switched off to
reduce the risk of damage to the drivetrain.
Tow bar and towing cable
The vehicle can be towed with a tow bar or tow-
ing cable. Both drivers should be familiar with
the special considerations when towing, especial-
ly when using a towing cable.
Always make sure the traction force does not ex-
ceed the permitted level and there are no shock
loading conditions. There is always the risk of the >

8S1012721BE
Emergency assistance

coupling becoming overloaded when driving off-
road.
For the most safety and security, drive with a tow
bar. You should use a towing cable only if a tow
bar is not available. Use a towing cable made of
synthetic elastic cable similar elastic material.

ZA\ WARNING
— Towing highly increases the risk of an acci-
dent, for example from colliding with the
towing vehicle.
— To reduce the risk of an accident, do not al-
low anyone to remain inside the vehicle
when it is being transported by a tow truck
or a special transporter.

® Note
— If normal towing is not possible, for exam-
ple if the transmission is faulty or if the
towing distance is greater than 30 miles
(50 km), then transport the vehicle ona
special carrier.
— If the vehicle is towed by a tow truck at the
axle that is not permitted, this can cause se-
vere damage to the transmission.
— The vehicle must not be tow started for
technical reasons.
G) Tips
— If there is a power failure, the selector lever
will not move out of the "P" position. The
parking lock must be released using the
emergency release before towing the vehi-
cle > page 88.
— Follow the local legal regulations for tow-
ing.
Read and follow the important information un-
der > page 250.
Preparations
> Only secure the towing cable or tow bar at the
designated towing loops > page 2517,
=> page 252.
> Make sure the towing cable is not twisted. Oth-
erwise it could disconnect from the towing loop
while towing.
> Switch the emergency flashers on in both
vehicles > page 38. However, do not do this if it
prohibited by law.
Towing vehicle (front)
> Only start to drive when the towing cable is
taut.
> Be especially careful when accelerating.
» Avoid sudden braking or driving maneuvers.
Vehicle being towed (rear)
> Make sure the ignition is switched on so that
the steering wheel is not locked and so that you
can use the turn signals, the horn, and the
windshield wipers if needed > /A\.
> Switching it off before the vehicle has stopped
may impair the function of the brake booster
and power steering. You would then need to
use more force to steer and brake the vehicle.
> Release the parking brake > page 79.
> Select the “N” selector lever position.
> Make sure the towing cable is always taut.

ZA\ WARNING
— Never tow a vehicle using a tow bar or tow-
ing cable if the vehicle does not have electri-
cal power.
— If the vehicle runs out of power while it is
being towed, stop towing the vehicle imme-
diately and consult an authorized Audi deal-
er or qualified repair facility.
