Driving


— 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 109. This especially ap-
plies when towing a trailer.
@ 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 269.

Special driving situations
Sy Seas ASLAN LLS)
Applies to: RS models
When driving in a sporty style, the wear on all ve-
hicle components is greatly increased, especially
on the engine, transmission, tires, brakes, and
suspension. This can result in increased wear. Al-
so note the following 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 must be
brought to a minimum temperature of 158 °F
(70°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:
— Dynamic Audi drive select mode* > page 111
— Launch Control > page 98
— Limit ESC > page 116
@ Tips
Wear caused by load does not constitute a ve-
hicle fault as defined by the terms of the war-
ranty.
Driving uphill and downhill
When driving uphill, downhill, or at high alti-
tudes, note the following information:
— Drive slowly and carefully.
— Do not try to turn around if you cannot safely
drive on an incline or hill. Instead, drive in re-
verse.
— When driving down hills, you can activate the
hill descent control if you press the brake pedal
while driving in “D” gear. The automatic trans-
mission will select a gear suitable for driving
down the hill and will attempt to maintain the
speed at which the vehicle was traveling at the
time the brake pedal was pressed. Press the
brake pedal if necessary. The hill descent con-
trol will switch off once the hill levels out or
you press the accelerator pedal.
— Utilize the engine braking effect when driving
downhill by selecting the “S” driving program
=> page 96. This especially applies when towing
a trailer. This reduces the load on the brakes.
— Apply the brakes in intervals and do not press
the brake pedal continuously.

ZA\ WARNING
— Only drive on inclines that your vehicle is de-
signed to handle. Do not exceed the hill
climbing ability of your vehicle. Your vehicle
could tip or slide.
— Do not drive at an angle on steep inclines
and hills. If your vehicle is about to tip, you
must immediately start steering in the di-
rection of the downward slope to reduce the
risk of an accident.
— Always be ready to brake when using the hill
descent control function.

The ESC sport mode can be activated. Also refer
to the important information regarding driving
with ESC limited > page 116.
Suspension
PCED aN eer ute)
Applies to: vehicles with suspension control
The adaptive dampers are an electronically-con-
trolled damping system. The firmness of the sus-
pension will adapt to the driving conditions and
the driving situation. The settings depend on the
selected Audi drive select* mode.
Air suspension
Applies to: vehicles with air suspension
The air suspension is an electronically-controlled
suspension and leveling system. The firmness of
the suspension will adapt to the driving condi-
tions and the driving situation. The system balan-
ces out changes in load. The vehicle level will also
112
adapt gradually to the vehicle speed in order to
reduce the wind resistance at high speeds and in-
crease the ground clearance at low speeds. The
settings depend on the selected Audi drive se-
lect* mode.
Displaying the vehicle level
» Applies to MMI: Select on the home screen: VE-
HICLE > Audi drive select.
The filled-in boxes represent the current vehicle
level. The more boxes that are filled in, the high-
er the ground clearance. The box that corre-
sponds with the current vehicle level will flash
while the vehicle is lifting or lowering. The target
level is highlighted in color.
Raising the vehicle
> Applies to MMI: Select on the home screen: VE-
HICLE > Audi drive select.
> Press Raise to reach the highest vehicle level
and thus the maximum ground clearance.
» Press Lower to lower the vehicle down again.
The vehicle will lower at speeds of approximately
22 mph (35 km/h) and below. This function may
only be used temporarily when increased ground
clearance is necessary. It is not intended for long
drives.
@) Note
— Also refer to the information about ground
clearance > page 112.
— When transporting the vehicle on a road
carrier,
rail carrier, ship carrier, or other car-
rier, it may only be secured at the running
surfaces of the tires (circumference). Secur-
ing the vehicle at the axle components, sus-
pension struts, or towing eyes is not permit-
ted because the pressure in the air suspen-
sion struts can change during transport. The
vehicle might not be secured sufficiently if
this happens.
Ground clearance
The vehicle height and clearance can be influ-
enced by the following factors:
— Change in temperature

Trailer towing

Trailer towing
Driving with a trailer
eT e e eeu)
Your vehicle is primarily intended for transport-
ing people and luggage. However, if you drive
with a trailer, follow the technical requirements,
the operation and driving tips, and the legal reg-
ulations.
Driving with a trailer affects the vehicle's energy
usage, performance, and wear. It also requires
higher concentration from the driver.

Z\ WARNING
Do not transport any people in a trailer due to
the risk of fatal injury.
Technical requirements
Trailer hitch

Only use a trailer hitch with a removable ball
hitch mount and ball hitch. The trailer hitch must
be permitted for the vehicle, the trailer and the
permitted total weight of the trailer being
pulled. Above all, it must be securely and safely
attached to the vehicle trailer.
Never mount a trailer hitch on the bumper. The
trailer hitch must be mounted in a way that does
not impair the function of the bumper. Do not
make any changes to the exhaust system and the
brake system.
Check regularly if the trailer hitch is securely
mounted. Always follow the instructions given by
the trailer hitch manufacturer.
Trailer brakes
If the trailer has its own brake system, then fol-
low the manufacturer specifications. However,
the brake system on the trailer must never be
connected to the vehicle brake system.
Engine cooling system
Driving with a trailer means a higher load on the
engine and the cooling system. The cooling sys-
tem must be designed for additional load and
contain enough coolant > @®.
CG) Note
Longer inclines cannot be driven without a
suitable cooling system, especially if the out-
side temperatures are high. Otherwise, this
increases the risk of engine damage.
Operating instructions
Towing capacity
Your vehicle can only be operated with class 1 or
class 2 trailers.
Load distribution
Poor cargo load and distribution can negatively
impact vehicle handling. Load the trailer based
on the following criteria as much as possible:
— Store objects in the vehicle luggage compart-
ment, if possible. The vehicle should always
carry the heaviest possible load and the trailer
should have the lightest possible load.
— Distribute the load in the trailer so that the
heavy objects are as close to the axle as possi-
ble.
— Secure objects so that they do not slide.
— Utilize the maximum permitted tongue weight
if possible.
Tires
Set the tire pressure on your vehicle for a “full
load”; see the tire pressure sticker > page 284. If
necessary, also adjust the tire pressure on the
trailer according to the manufacturer's specifica-
tions.
The trailer and the vehicle should be equipped
with winter tires when driving in winter tempera-
tures.
Outside mirrors
If you cannot see the traffic behind the trailer
with the standard exterior mirrors, then you
must attach additional exterior mirrors. Adjust
them so you have a sufficient visibility behind
you.
Exterior lighting
Follow the legal regulations for lighting on your
trailer that are applicable in the country where
135
>

Trailer towing

you are operating the vehicle. Contact an author-
ized Audi dealer or authorized Audi Service Facili-
ty for more information.
Before you start driving, check all lighting equip-
ment on the trailer while it is hitched to the vehi-
cle.
The headlight range control automatically ad-
justs the light range of the headlights.
Safety chains
Make sure the safety chains are correctly applied
when pulling a trailer. The chains should hang
enough so that the trailer can drive around
curves. However, they must not touch the
ground.
Air suspension
Applies to: vehicles with air suspension
The Audi drive select* Comfort mode > page 111
must be selected before you adjust the tongue
weight on the trailer and hitch the trailer >@,
=> page 112.
Likewise, the vehicle cannot be raised manually
using the Raise function > page 112.
The air suspension trailer mode must be switched
on.
Applies to MMI: select on the home screen: VE-
HICLE > Settings & Service > Air suspension:
trailer.
Switch trailer mode off again when you are no
longer towing a trailer.
When using rear carrier systems that are mount-
ed directly on the trailer hitch ball head, you can
also switch trailer mode off manually.
If you must drive on roads that are in poor condi-
tion, you can raise the vehicle again after hitching
the trailer or after adjusting the tongue weight
=> page 112.
Vehicle levels below the values set in the Com-
fort level will no longer be available, even if you
are lowering the vehicle manually.
136

ZA WARNING
Applies to: vehicles with air suspension
— Never turn off trailer mode while driving
when a trailer is hitched, because then the
restrictions for controlling the vehicle level
will be turned off.
— Driving with a trailer on unpaved roads when
the vehicle is raised may change the vehicle
handling. Adapt your speed.
— Note that the vehicle will lower automatical-
ly at certain speeds if you have lifted the ve-
hicle manually.
C) Note
— Applies to: vehicles with air suspension: Se-
lect the Audi drive select* Comfort mode.
Otherwise, the tongue load specified for
your vehicle will no longer be applicable.
— Attachments retrofitted on the vehicle may
cause damage, especially on the trailer
hitch ball head. In cases of damage, have
the function checked by an authorized Audi
dealer or authorized Audi Service Facility.
@) Tips
— Block the wheels with chocks when parking
on inclines if the trailer is loaded.
— Audi recommends having the vehicle in-
spected between the inspection intervals if
you tow a trailer frequently.
— Avoid driving with a trailer during the vehi-
cle break-in period.
Pie Rie Relig
Driving with a trailer requires extra caution.

Speed
Adhere to the legal speed limits. Follow the legal
regulations that are applicable in the country
where you are operating the vehicle.
As the speed increases, the driving stability of
the trailer decreases. Therefore you should not
exceed the maximum legal speed limit when
there are unfavorable road, weather, and/or wind
conditions. This especially applies when driving
downhill.

4K8012721BF
Trailer towing

Hill
When you start driving uphill or downhill, trailers
may tilt or sway sooner than when driving ona
level surface. If small swaying movements have
already occurred, you can stabilize the trailer by
firmly braking immediately. Never attempt to
“straighten out” the trailer by accelerating.
Conventional drive system: Downshift before
driving on hills to utilize the engine braking ef-
fect SA.
Plug-in hybrid drive system: Reduce the speed
and use the recuperation braking effect
=> page 101 to relieve the brakes > A\.
Brakes
When using a trailer with overrun brakes, first
brake gently then quickly. This reduces the risk of
jerking while braking if the trailer wheels lock up.
Engine coolant temperature
Pay attention specifically to the coolant tempera-
