Driving

— Do not let the engine run while the vehicle
parked.
— Use the Start/Stop system.
— Utilize the engine braking effect.
— Avoid driving short distances when possible.
@ Tips
The amount of noise produced by the vehicle
can increase significantly when driving with a
sporty style. Show respect to others around
you and the environment with the way you op-
erate your vehicle, especially at night.
tiger le (aay
Your vehicle is equipped with an intelligent ener-
gy management system for distributing electrici-
ty. This significantly improves the starting ability
and increases the vehicle battery life.
G) Tips
— If you drive short distances frequently, the
vehicle battery may not charge enough
while driving. As a result, convenience func-
tions for electrical equipment may be tem-
porarily unavailable.
— The vehicle battery will gradually drain if
the vehicle is not driven for long periods of
time, or if electrical equipment is used
when the engine is not running. To ensure
that the vehicle can still be started, the
electrical equipment will be limited or
switched off.
B Drive system: malfunction! Safely stop vehi-
cle
There is a malfunction in the drive system. The
brake booster and the power steering may stop
working. Stop the vehicle immediately or as soon
as possible and do not continue driving. Have the
problem corrected by an authorized Audi dealer
or authorized Audi Service Facility.
B Drive system: malfunction! Please contact
Service
There is a malfunction in the drive system. Drive
slowly to an authorized Audi dealer or authorized
Audi Service Facility to have the malfunction cor-
rected.
Start/Stop system
Applies to: vehicles with Start/Stop system
The Start/Stop system can help increase fuel
economy and reduce CO2 emissions.
In Start/Stop mode, the engine shuts off auto-
matically when stopped, for example at a traffic
light. The ignition and important assist systems
such as power steering and the brake booster will
remain available during the Stop phase. The en-
gine will restart automatically when needed.
The Start/Stop system is automatically activated
once the ignition is switched on.
Switching the Start/Stop system off and on
The & button is located above the selector lever
in the center console. The LED in the button turns
on when the function is switched off.
> Press & to switch on or off.
If you switch the system off during a Stop phase,
the engine will start again automatically.
Basic requirements
— The driver's door and hood must be closed.
—"P","N", or"D" must be engaged.
— The steering wheel must not be turned far in ei-
ther direction.
— The vehicle must have driven faster than 2 mph
(3 km/h) since the last time it stopped.
— The vehicle is not in trailer mode.
() Note
Always switch the Start/Stop system off when
driving through water > page 101.
@ Tips
— Depending on the driving situation, the en-
gine may already stop when coasting before
the vehicle has come to a complete stop )).

4M1012721BA
Driving

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\.
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.
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.

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 106. This especially ap-
plies when towing a trailer.
(i) 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 241.
EG / oO} Brakes: malfunction! Safely stop ve-
hicle
There is a malfunction in the brake system. If
BS / Gana B also turn on, there is a malfunc-
tion in the ABS, ESC, and braking distribution.
Do not continue driving. See an authorized Audi
dealer or authorized Audi Service Facility for
103

Driving


level ground and secure it by engaging the
"P” gear. Contact an authorized Audi dealer
or authorized Audi Service Facility for assis-
tance.

@ Tips
— On steep inclines, especially when in trailer
mode, the vehicle may roll backwards unin-
tentionally when starting to drive. To re-
duces the risk of this happening, pull and
hold the ©) switch while pressing the accel-
erator pedal. If enough drive power has
built up at the wheels and the vehicle does
not roll backwards, then release the switch
to start to drive.
— If you leave the vehicle when “D” or “R” are
engaged, the parking brake will be set auto-
matically.
— Noises when the parking brake is set and re-
leased are normal and are not a cause for
concern.
— The parking brake goes through a self-test
cycle at regular intervals when the vehicle is
stopped. Any noises associated with this are
normal.
Emergency braking function
Emergency braking should only be used in an
emergency, if the standard brake pedal is mal-
functioning or obstructed. When the emergency
braking function is activated, the braking effect is
similar to a heavy braking maneuver.
>» Pull and hold the (®) switch while driving.
> An audio warning signal will sound and emer-
gency braking will begin.
> If you press the accelerator pedal, emergency
braking will be canceled.

ZA\ WARNING
Heavy braking while driving through curves or
in poor road or weather conditions can cause
the vehicle to slide or the rear of the vehicle to
swerve, which increases the risk of an acci-
dent.

Driving

Special driving situations
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 97. This especially applies when towing
a trailer. This reduces the load on the brakes.
— Brake in intervals and do not press the brake
pedal continuously.
— Use the hill descent assist if necessary
=> page 107
Inclinometer
Applies to: vehicles with a tilt angle display
You can display the vehicle's sideways angle and
lengthwise angle in relation to the horizon.
— Applies to: MMI: Select on the home screen:
VEHICLE > Vehicle data.
— You may need to scroll down to the Inclinome-
ter display.
The sideways angle of your vehicle should not ex-
ceed the yellow range in the gauge. If it reaches
the red range, there is a risk that the vehicle
might tip.
The steering wheel angle, the elevation, the com-
pass direction, and the geo-coordinates of the
current vehicle position are displayed in addition
to the current vehicle angle. You will also receive
information about the maximum sideways and
lengthwise angle that was reached in the current
106
driving cycle. These values are reset when the ig-
nition is switched off.
Note that the accuracy of the display depends on
the driving situation.

A 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.
— Applies to: vehicles with an inclinometer: Do
not rely only on the inclinometer when as-
sessing the driving situation.
Ole MLAs)
Your vehicle is not an offroad vehicle. Note the
following points when driving offroad:

— Drive slowly and carefully.
—To reduce the risk of underbody damage, pay
attention to the vehicle's ground clearance and
drive across raised areas of the ground with the
wheels on one side of the vehicle, instead of al-
lowing the center of the vehicle to pass over the
raised areas.
—To reduce the risk of becoming stuck, drive
through sandy or swampy areas at a steady
speed and without stopping, if possible.
If necessary, use the following functions:
— Audi drive select* Offroad mode > page 108
— Hill descent assist* > page 107
—Inclinometer* > page 106
— Raising the vehicle > page 109
— Limit ESC > page 113

ZA WARNING
Only drive in terrain that is suitable for the ve-
hicle and your driving ability.

Trailer towing

Trailer towing
Driving with a trailer
General information
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 > @.

ZA WARNING
— Never mount a "weight-distributing" or
"load-balancing" trailer coupler as the trailer
hitch. The vehicle was not designed for
these types of trailer hitches. The trailer
hitch can malfunction and the trailer can
break off from the vehicle.
— If the trailer is equipped with electronic
brakes, these brakes cannot be activated by
a factory-installed control system, which in-
creases the risk of an accident.
—To reduce the risk of injury, always remove
the ball hitch mount if no trailer is mount-
ed
® 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

The permitted towing capacity must not be ex-
ceeded under any circumstances > page 298.
You can drive up larger inclines if you are not us-
ing the maximum towing capacity.
The specified towing weights only apply at eleva-
tions up to 3,200 ft (1,000 m) above sea level. As
the elevation increases, the engine power de-
creases due to the decreasing air pressure. This
reduces the hill climbing ability and towing ca-
pacity. For every additional 3,200 ft (1,000 m),
the maximum permitted towing weight must be
reduced by approximately 10%. The permitted
towing weight is the combined weight of the
(loaded) vehicle and the (loaded) trailer.
Tongue weight
The maximum permitted tongue weight of the
trailer drawbar on the trailer hitch ball head must
not be exceeded.
For driving safety, always using the maximum
permitted tongue weight is recommended, but
not
exceed it. Distributing the cargo in the trailer >
115

Trailer towing

correctly will help to achieve this weight. Having
the tongue weight too low affects the vehicle's
handling.
You can determine the tongue weight using a
tongue weight scale, a bathroom scale, or a pub-
lic weigh station, for example.
The permitted tongue weight of your vehicle can
be found in the vehicle documentation or in
=> page 298.
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 256. If
necessary, also adjust the tire pressure on the
trailer according to the manufacturer's specifica-
tions.
The tire pressure must be increased an additional
3 PSI (0.2 bar) for towing loads over 6,600 lbs
(3,000 kg).
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.
116
Exterior lighting
Follow the legal regulations for lighting on your
trailer that are applicable in the country where
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.
The turn signals are activated in trailer mode if
the & indicator light blinks. If a turn signal on
the trailer or on the vehicle fails while in trailer
mode, the indicator light will not blink twice as
fast to indicate this.
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 108
must be selected before you adjust the tongue
weight on the trailer and hitch the trailer >,
=> page 109.
For vehicles with a factory-installed trailer hitch,
the air suspension trailer mode will automatically
switch on if you connect the trailer cable to the
socket.
For vehicles with a retrofitted trailer hitch, you
must switch on the air suspension trailer mode
manually.
Applies to MMI: select on the home screen: VE-
HICLE > Settings & Service > Air suspension:
trailer.
Switch it off again when you are no longer towing
a trailer.
When using carrier systems that are mounted di-
rectly on the trailer hitch ball head, you can also
switch trailer mode off manually.

4M1012721BA
Trailer towing

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 109.
You can also increase ground clearance by select-
ing the Audi drive select* offroad or allroad
modes > page 108.
Vehicle levels below the values set in the comfort
level will no Longer be available, even if you are
lowering the vehicle manually.

IX WARNING
— 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.
® 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.
— Having the vehicle inspected between the
inspection intervals is recommended if you
tow a trailer frequently.
— Avoid driving with a trailer during the vehi-
cle break-in period.
Pe MO le
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.
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.
Downshift before driving on hills to utilize the en-
gine braking effect > 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-
ture display when there are high outside temper-
atures, and when driving on long inclines
=> page 13. Shift to a higher gear in a timely man-
ner.

Z\ WARNING
Constant braking causes the brakes to over-
heat and can substantially reduce braking per-
formance, increase braking distance, or cause
complete failure of the brake system.
