Driving


— Do not leave your vehicle unattended while
the engine is running, because this increases
the risk of an accident.
— If the parking brake is set, it can release au-
tomatically when the accelerator pedal is
pressed. To reduce the risk of an accident,
do not inadvertently press the accelerator
pedal and always shift into “P” when the ve-
hicle is stopped.
— If you leave the vehicle, switch the ignition
off and take the key with you. This is espe-
cially important when leaving persons or an-
imals in the vehicle. Otherwise, the vehicle
could start unintentionally, the parking
brake could release, or electronic equipment
could activate, which increases the risk of an
accident.
— No persons or animals should be left in a
locked vehicle. Locked doors make it more
difficult for emergency workers to enter the
vehicle, which puts lives at risk.
— If you do not begin driving immediately af-
ter releasing the brake pedal, your vehicle
may begin to roll backward. Press the brake
pedal
or set the parking brake immediately.
@) 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 back-
ward. Do not try to hold the vehicle in place
by pressing and holding the accelerator pedal.
The transmission can overheat, which increas-
es the risk of damage.
Hill hold assist
If you take your foot off of the brake pedal when
driving on hills, the braking force will be held for
several seconds. At that time, you can start driv-
ing without the vehicle rolling backward.

Requirement: the driver's door must be closed,
the engine must be on, and the vehicle must be
traveling uphill.
> To activate hill hold assist, press and hold the
brake pedal for several seconds while the vehi-
cle is stationary.
ZA WARNING
— If you do not begin driving immediately af-
ter releasing the brake pedal, your vehicle
may begin to roll backward. Press the brake
pedal
or set the parking brake immediately.
— The hill hold assist cannot hold the vehicle
on inclines in every scenario (for example,
on slippery or icy ground).

The transmission has switched out of tiptronic
mode. Switch back to automatic mode with the
selector lever > page 97.
Drive system
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 and other drive com-
ponents.
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).
Conventional and mild hybrid drive system
Applies to: vehicles with a conventional drive system or a mild
hybrid drive system
Vehicles with a conventional or mild hybrid drive
system are powered by a combustion engine. It
uses fuel to recover energy.

driving
Your driving style greatly influences the amount
of fuel and energy consumed, the environmental
impact, and the wear on the engine, brakes, and
tires. Note the following information for efficient
and environmentally-conscious driving:
— 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.
— Avoid driving at high speeds.
— 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.
— Make sure the tire pressure is correct.
— Have maintenance performed regularly on the
vehicle.
— Do not drive with winter tires during the summ-
er.
— 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.
Energy management
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.
(Gi) Tips
— If you drive short distances frequently, the
vehicle battery may not charge enough

Checking and Filling


the high temperature of the emissions sys-
tem could start a fire.
— Do not apply underbody protectant in the
exhaust system area, because this increases
the risk of fire.
Catalytic converter
Follow the safety precautions > page 230, Gener-
al information.


The vehicle may only be driven with unleaded
gasoline, or the catalytic converter will be de-
stroyed.
Never drive until the tank is completely empty.
The irregular supply of fuel that results from that
can cause engine misfires. Uncombusted fuel
could enter the exhaust system, which could
cause overheating and damage to the catalytic
converter.
Malfunction Indicator Lamp (MIL)
If the S indicator light blinks or turns on, there
is a malfunction that is causing poor emissions
quality and that could damage the catalytic con-
verter. Drive slowly to an authorized Audi dealer
or authorized Audi Service Facility to have the
malfunction corrected.
The indicator light can also turn on if the fuel fill-
er cap is not closed correctly > page 228).
Engine compartment
(er eel lacela)
Special care is required if you are working in the
engine compartment
When performing work in the engine compart-
ment, such as checking and filling fluids, there
is a risk of injury, scalding, accidents, and
burns. For this reason, follow all the warnings
and general safety precautions provided in the
following information. The engine compart-
ment is a dangerous area in the vehicle. > A\.

) Depending on the engine and country

ZA WARNING
— Turn the engine off.
— Switch the ignition off.
— Set the parking brake.
— Select the “P” (Park) selector lever position.
— Allow the engine to cool.
— Keep children away from the engine com-
partment.
— Never spill fluids on a hot engine. These flu-
ids (such as the freeze protection contain
in the coolant) can catch fire.
ed
— Avoid short circuits in the electrical system.
— Never reach into the radiator fan. The fan is
temperature-controlled and can turn on
suddenly, even when the ignition is switched
off.
— Never open the hood when there is steam or
coolant escaping from the engine compart-
ment, because there is a risk that you could
be burned. Wait until no steam or coolan
escaping.
tis
— The cap on the coolant expansion tank must
never be opened when the coolant is hot.
The cooling system is under pressure. There
is a risk of burns
—To protect your face, hands, and arms fro m
hot steam or coolant, cover the cap with a
thick cloth when opening.
— Do not remove the engine cover under an
circumstances. This increases the risk of
burns.
y
— Due to the risk of electric shock, never touch
the ignition cable or other components in
the electronic high-voltage ignition syste
when the engine is running or is starting.
m
— Ifa gear is engaged while the vehicle is sta-
tionary and the engine is running, do not
press the accelerator pedal inadvertently.
Pressing the accelerator pedal will cause the
vehicle to move, and this could result in an
accident.
— If inspections or repairs must be performed
while the engine is running, moving compo-
nents (such as the ribbed belt, generator,
and radiator fan) pose an additional risk.

Glossary of tire and loading
terminology
Accessory weight
means the combined weight (in
excess of those standard items
which may be replaced) of auto-
matic transmission, power steer-
ing, power brakes, power win-
dows, power seats, radio, and
heater, to the extent that these
items are available as factory-in-
stalled equipment (whether in-
stalled or not).
Aspect ratio
means the ratio of the height to
the width of the tire in percent.
Numbers of 55 or lower indicate a
low sidewall for improved steer-
ing response and better overall
handling on dry pavement.
Bead
means the part of the tire that is
made of steel wires, wrapped or
reinforced by ply cords and that is
shaped to fit the rim.
Bead separation
means a breakdown of the bond
between components in the bead.
248
Cord
means the strands forming the
plies in the tire.
Cold tire inflation pressure
means the tire pressure recom-
mended by the vehicle manufac-
turer for a tire of a designated
size that has not been driven for
more than a couple of miles (kilo-
meters) at low speeds in the three
hour period before the tire pres-
sure is measured or adjusted.
Curb weight
means the weight of a motor ve-
hicle with standard equipment in-
cluding the maximum capacity of
fuel, oil, and coolant, air condi-
tioning and additional weight of
optional equipment.
Extra load tire
means a tire designed to operate
at higher loads and at higher in-
flation pressures than the corre-
sponding standard tire. Extra load
tires may be identified as “XL”,
“xl”, “EXTRA LOAD”, or “RF” on
the sidewall.

Wheels

a label. The label is located on the
B-pillar > fig. 164, > fig. 165.
Use the tire pressure specified for
a normal vehicle load when the
vehicle is partially loaded > table
on page 257. If driving the vehi-
cle when fully loaded, you must
increase the tire pressure to the
maximum specified pressure > A.
Checking and correcting tire
pressure
>Check the tire pressure at least
once per month and also check it
before every long drive.
> Always check the tire pressure
when the tires are cold. Do not
reduce the pressure if it increas-
es when the tires are warm.
>Refer to the sticker > fig. 165
for the correct tire pressure.
>Correct the tire pressure if nec-
essary.
> Store the new tire pressure in
the MMI & page 264.
> Check the pressure in the spare
tire*. Always maintain the maxi-
mum temperature that is speci-
fied for the tire.
256


Z\ WARNING
Always adapt the tire pressure
to your driving style and the ve-
hicle load.
—Overloading can lead to loss of
vehicle control and increase
the risk of an accident. Read
and follow the important safe-
ty precautions in > page 258.
—The tire must flex more if the
tire pressure is too low or if
the vehicle speed or load are
too high. This heats the tire up
too much. This increases the
risk of an accident because it
can cause the tire to burst and
result in loss of vehicle con-
trol.
—Incorrect tire pressure increas-
es tire wear and has a negative
effect on driving and braking
behavior, which increases the
risk of an accident.

@) Note
Replace lost valve caps to re-
duce the risk of damage to the
tire valves.
(*) For the sake of the envi-
ronment
Tire pressure that is too low in-
creases fuel consumption.

Wheels

& Loose wheel warning: malfunction! See
owner's manual
There is a system malfunction. Drive immediately
to an authorized Audi dealer or authorized Audi
Service Facility to have the malfunction repaired.

ZA WARNING
Wheel bolts that are tightened incorrectly can
become loose and result in loss of vehicle con-
trol, which increases the risk of an accident.
— If a message appears, reduce your speed im-
mediately and avoid any hard steering or
braking maneuvers. Stop as soon as possible
and check the wheel bolts.
— Check your wheels for damage. Have the
damaged wheels checked and/or replaced
immediately by an authorized Audi dealer or
authorized Audi Service Facility.
— Under certain conditions (such as a sporty
driving style, winter conditions, or unpaved
roads), the message may be delayed.
— The driver is responsible for ensuring that

the wheels are attached correctly.
G) Tips
— The loose wheel warning system can also
stop working when there is an ESC malfunc-
tion.

— Using snow chains may result in a system
malfunction.
Winter tires significantly improve the vehicle's
handling when driving in winter conditions. Be-
cause of their construction (width, compound,
tread pattern), summer tires provide less traction
on ice and snow.
> Use winter tires on all four wheels.
> Only use winter tires that are approved for your
vehicle.
> Please note that the maximum permitted
speed may be lower with winter tires > A\ in
General information on page 245. An author-
ized Audi dealer or authorized Audi Service Fa-
cility can inform you about the maximum per-
mitted speed for your tires.
> Check the tire pressure after installing wheels
=> page 255.
The effectiveness of winter tires is reduced great-
ly when the tread is worn down to a depth of
0.16 in (4 mm). The characteristics of winter tires
also decrease greatly as the tire ages, regardless
of the remaining tread.
@) For the sake of the environment
Reinstall summer tires at the appropriate
time, because they provide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear, and fuel
consumption.
(i) Tips
You can also use all season tires instead of
winter tires. Please note that in some coun-
tries where winter tires are required, only win-
ter tires with the 4 symbol may be permit-
ted.
Snow chains improve both driving and braking in
winter road conditions.
> Only install snow chains on the front wheels.
> Check and correct the seating of the snow
chains after driving a few feet, if necessary. Fol-
low the instructions from the manufacturer.
> Note the maximum speed of 30 mph
(50 km/h). Observe the local regulations.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authorized Audi dealer or author-
ized Audi Service Facility to see if you may use
snow chains.
Use fine-mesh snow chains. They must not add
more than 0.40 inch (10.5 mm) in height, includ-
ing the chain lock.
You must remove the snow chains on roads with-
out snow. Otherwise, you could impair driving
ability and damage the tires.
