2021 AUDI E-TRON snow chains

Driving dynamic

Selective wheel torque control
Selective wheel torque control is used when driv-
ing on curves. Braking is targeted toward the
wheels on the inside of the curve as needed. This
allows more precise driving in curves.
Power steering
The ESC can also support vehicle stability
through steering.

ZA\ WARNING
— The ESC and its integrated systems cannot
overcome the limits imposed by natural
physical laws. This is especially important on
slippery or wet roads. If the systems begin
acting to stabilize your vehicle, you should
immediately alter your speed to match the
road and traffic conditions. Do not let the in-
creased safety provided tempt you into tak-
ing risks. This could increase your risk of a
collision.
— Please note the risk of a collision increases
when driving fast, especially through curves
and on slippery or wet roads, and when driv-
ing too close to objects ahead. There is still
a risk of accidents because the ESC and its
integrated systems cannot always prevent
collisions.
— Accelerate carefully when driving on
smooth, slippery surfaces such as ice and
snow. The drive wheels can spin even when
these control systems are installed and this
can affect driving stability and increase the
risk of a collision.
— As the vehicle load increases, especially the
roof load, the vehicle's center of gravity also
increases along with the risk of the vehicle
tipping. To reduce the risk of an accident, al-
ways adapt your driving style to the current
conditions and avoid sudden driving maneu-
vers.

@) Tips
— The ABS and ASR only function correctly
when all four wheels have a similar wear
condition. Different tire sizes can lead toa
reduction in motor power.
106
— You may hear noises when the systems de-
scribed are working.
The So button (or #, depending on the model)
for controlling the ESC is located in the center
console, in front of the selector lever. The ESC is
automatically switched on when the ignition is
switched on.
Limiting ESC
In some situations, it may make sense to limit
the stabilizing function of the ESC so that the
wheels can spin, for example to rock a vehicle to
free it when it is stuck or to drive with snow
chains. The ESC can also be limited to provide
more sporty driving characteristics with fewer
stabilizing corrective actions.
—To limit the ESC, press the 0 button briefly.
The B indicator light will turn on.
— To completely reactivate the ESC stabilization
function, press the button again. The indicator
light turns off.
Depending on the Audi drive select mode that is
selected, one of the following ESC modes will be
selected automatically:
— sport - this mode is designed for driving ona
level surface. It is used in all Audi drive select
modes except offroad.
— offroad - this mode is suited for driving offroad
and is designed for uneven terrain or loose
ground. If you select the offroad Audi drive se-
lect mode, the offroad ESC mode will be auto-
matically used.
Switching off ESC
For a more active control of the vehicle where the
stabilizing functions of the ESC cannot intervene,
the ESC can be switched off.
— To switch off the ESC, press and hold the Sor
button for more than three seconds. The B
and Ea indicator lights turn on.
— To completely reactivate the ESC stabilization
function, press the button again. The indicator
lights turn off.

Assist systems



with limitations may not be detected at all.
Always monitor the traffic and the vehicle's
surroundings directly and do not become dis-
tracted.

@) Note
— Obstacles may disappear from the measure-
ment range when approaching them, even if
they were already detected.
—Insome situations, the ability of the sen-
sors and cameras to detect and display cer-
tain objects may be limited.
— Objects located above the coverage area,
such as bumpers on parked cars, garage
doors that are partially open, or objects
that are hanging
— Low obstacles
— Narrow objects, such as barrier chains, fo-
liage, poles, or fences
— Projecting objects, such as trailer draw
bars
— Objects with certain surfaces and struc-
tures, such as fabric
@ Tips
— The sensors and cameras and the areas
around them must not be obstructed be-
cause this can impair the function of the
systems that depend on them. Make sure
that the sensors and cameras are free of
snow, ice, and other deposits. Do not use
any accessories, stickers, or other objects
that extend into the range of the sensors
and cameras.
— On vehicles that have factory-installed li-
cense plate brackets on the front of the ve-
hicle, the brackets may only be replaced
with ones that are the same size and made
of the same material. Do not install any li-
cense plate brackets on the front of vehicles
that do not have factory-installed brackets.
Otherwise, the function of the system could
be impaired.
— The function of the sensors and cameras
may be limited when light and visibility con-
ditions are poor, for example when driving
into a tunnel, when there is glare, or when
there are reflective objects.
— External ultrasonic sensors, such as those in
other vehicles, can interfere with the sen-
sors.
— The coverage areas of the sensors > fig. 90
and cameras > fig. 91 are diagrams and do
not represent a true-to-scale image of the
sensor ranges.
— The system complies with United States FCC
regulations and ISED regulations
> page 288.

Wheels


ZA\ WARNING
Wheel bolts that are tightened or repaired in-
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct tightening specifi-
cation, see S page 272, Finishing.
— Always keep the wheel bolts and the threads
in the wheel hub clean and free of grease.
— Only use wheel bolts that fit the rim.
— Always have damaged rims repaired by an
authorized Audi dealer or authorized Audi
Service Facility. Never repair or disassemble
rims yourself, because this increases the risk
of an accident.
Loose wheel warning
Applies to: vehicles with loose wheel warning

Within the limits of the system, the loose wheel
warning in the instrument cluster warns you if
one or more wheels are loose.
Using the ABS sensors, the loose wheel warning
system compares the vibration characteristics of
the individual tires. If one or more wheels are
loose, it will be indicated in the instrument clus-
ter display with the & indicator light and a mes-
sage. If only one wheel is affected, the location
of that wheel will be indicated.
Messages
fi Wheel bolts loose. Please safely stop the ve-
hicle and check all wheel bolts!
Loose wheel warning for at least one wheel > A\.
Check the wheel bolts on all wheels with the
wheel wrench (vehicle tool kit). Have the tighten-
ing specification checked as soon as possible with
a torque wrench. Drive carefully until then. For
the correct tightening specification, see
=> page 272, Finishing.
fl Wheel assessment active. Please continue
driving carefully
After this message appears and you have checked
the wheel bolts, the assessment phase begins
when the vehicle is in motion. This may take sev-
eral minutes.
256
fi 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.

Z\ 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.
(i) 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 241. An author-
ized Audi dealer or authorized Audi Service Fa-
cility can inform you about the maximum per-
mitted speed for your tires.

Wheels

> Check the tire pressure after installing wheels
=> page 251.
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 en-
ergy use.
@) 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.
Tea
Snow chains improve both driving and braking in
winter road conditions.
> Only install snow chains on the rear 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.

ZA\ WARNING
Using incorrect snow chains or installing snow
chains incorrectly can result in loss of vehicle
control, which increases the risk of an acci-
dent.
(@) Note
— Snow chains can damage the rims and
wheel covers* if the chains come into direct
contact with them. Remove the wheel cov-
ers* first. Use coated snow chains.
— Do not install and use snow chains if there is
a malfunction in the air suspension*, be-
cause the vehicle height will be very low. If
you drive with snow chains anyway, the
wheel housings and other vehicle compo-
nents can be severely damaged.
G@) Tips
When using snow chains, it may be advisable
to limit the ESC > page 106.
Low-profile tires
Applies to: vehicles with low-profile tires

Compared to other tire/rim combinations, low-
profile tires offer a wider tread surface and a
larger rim diameter with shorter tire sidewalls.
This results in an agile driving style. However, it
may reduce the level of comfort and increase
road noise when driving on roads in poor condi-
tion.
Low-profile tires can become damaged more
quickly than standard tires when driving over
large bumps, potholes, manhole covers, and
curbs. Therefore, it is particularly important to
maintain the correct tire pressure > page 251.
To reduce the risk of damage to the tires and
rims, drive very carefully on poor roads.
Check your wheels regularly every 2,000 mi
(3,000 km) for damage. For example, check for
bulges/cracks on the tires or deformations/cracks
on the rims.
After
a heavy impact or damage, have the tires
and rims inspected or replaced immediately by

Wheels

minute and then stays on, there is system mal-
function. Try to store the correct tire pressures
= page 260. In some cases, you must drive for
several minutes after storing the pressures until
the indicator light turns off. If the indicator light
does turn off or turns on again after a short peri-
od of time, drive to an authorized Audi dealer or
authorized Audi Service Facility immediately to
have the malfunction corrected.

ZA\ WARNING
— If the tire pressure indicator appears in the
display, reduce your speed immediately and
avoid any hard steering or braking maneu-
vers. Stop as soon as possible and check the
tires and their pressure.
— The driver is responsible for maintaining the
correct tire pressure. You must check the
tire pressure regularly.
— Under certain conditions (such as a sporty
driving style, winter conditions, or unpaved
roads), the tire pressure monitoring system
indicator may be delayed.

(i) Tips
— The tire pressure monitoring system can al-
so stop working when there is an ESC mal-
function.
— Using snow chains may result in a system
malfunction.
— The tire pressure monitoring system in your
Audi was calibrated with “Audi Original
Tires” > page 248. Audi recommends using
these tires.
Storing tire pressures
Applies to: vehicles with Tire Pressure Monitoring System in-
dicator
If the tire pressure changes or a tire is replaced,
it must be confirmed in the MMI.
> Before storing the tire pressures, make sure the
tire pressures in all four tires meet the speci-
fied values and are adapted to the load
=>page 251.
> Switch the ignition on.
> Applies to MMI: Select on the home screen: VE-
HICLE > Settings & Service > Tire pressure
260
monitoring > Store tire pressure > Yes, store
now.
@) Tips
Do not store the tire pressures if snow chains
are installed.

4KE012721BF
Emergency assistance

> The wheel bolt tightening specification must be
120 ft lbs (160 Nm). Have it checked as soon as
possible with a torque wrench. Drive carefully
until then.
> Have the faulty wheel replaced as quickly as
possible.
Collapsible spare tire
Applies to: vehicles with collapsible spare tire
The collapsible spare tire is intended for short-
term use only. Have the damaged tire checked
and replaced if necessary by an authorized Audi
dealer or authorized Audi Service Facility as soon
as possible.
There are some restrictions on the use of the col-
lapsible spare tire. The collapsible spare tire has
been designed specifically for your type of vehi-
cle. Do not replace it with the collapsible spare
tire from another type of vehicle.
The collapsible spare tire is located in the lug-
gage compartment under the cargo floor cover.
Requirement: the vehicle tool kit > page 267 and
the compressor must be laid out.
Removing
> Lift the cargo floor using the handle.
> Turn the handwheel counter-clockwise and re-
move it.
> Remove the cover.
> Remove the collapsible spare tire.
You must inflate the collapsible spare tire before-
hand in order to use it.
Inflating
> Remove the valve cap from the collapsible
spare tire.
> Tighten the compressor hose on the collapsible
spare tire valve.
> Connect the compressor hose to a vehicle sock-
et and switch it on.
> Let the compressor run until the specified value
on the tire pressure sticker is reached
page 251, fig. 158>©.
> Screw the valve cap back onto the valve.
Returning to storage
> To release air, turn the valve insert. See an au-
thorized Audi dealer or authorized Audi Service
Facility.
> Turn the valve insert back once the air has been
released.
>» Wait several hours before placing the collapsi-
ble spare tire in the spare wheel well. Only then
will it fold down completely so that you can
store it securely.
> Then screw the valve cap back onto the valve.
> Secure the collapsible spare tire with the cover
and the handwheel.
>» Fold the cargo floor cover back into place.
Snow chains
Using snow chains on the collapsible spare tire is
not permitted for technical reasons.
If you have to drive with snow chains and a rear
tire fails, mount the collapsible spare tire in place
of a front tire. Install the snow chains on the
front tire that you removed, and install that in
place of the rear tire that failed.

Z\ WARNING
— Only use the collapsible spare tire in emer-
gencies and drive very carefully, especially if
it is more than six years old.
— The compressor and the hose can become
very hot during operation which increases
the risk of burn injuries.
— After installing a collapsible spare tire, the
tire pressure must be checked as quickly as
possible to reduce the risk of an accident.
— Do not drive faster than 50 mph (80 km/h)
with the collapsible spare tire. Driving faster
than that increases the risk of an accident.
— To reduce the risk of an accident, avoid hard
acceleration or braking and driving fast
around curves with the collapsible spare
tire.
— Never drive using more than one collapsible
spare tire, because this increases the risk of
an accident.
— Normal tires or winter tires must not be
mounted on the collapsible spare tire rim.
