272
The wheel bolts must be clean and loosen and
tighten easily. Check the contact surfaces for the
wheel and hub. Contaminants on these surfaces
must be removed before installing the wheel.

Z\ WARNING
— Read and follow the important information
and notes under > page 248.
— Never use the hex socket in the screwdriver
handle to tighten the wheel bolts. Using the
hex socket will not achieve the required
tightening torque, which increases the risk
of an accident.
C) Note
When removing or installing the wheel, the
rim could hit the brake rotor and damage the
rotor. Work carefully and have a second per-
son help you.
Unidirectional tires
A unidirectional tire profile is identified by arrows
on the tire sidewall that point in the running di-
rection. You must always maintain the specified
running direction. This is necessary to ensure the
tire's optimal performance in regard to adhesion,
running noise, and friction, and to reduce the risk
of
hydroplaning.

To benefit fully from the advantages of the uni-
directional tire design, you should replace faulty
tires as soon as possible and restore the correct
running direction on all of the tires.
> Reinstall the caps on the wheel bolts if necessa-
ry.
> Store the vehicle tool kit in its designated
place.
> If the removed wheel does not fit in the spare
wheel well, store it securely in the luggage
compartment © page 79.
> Check the tire pressure on the installed wheel
as soon as possible.
> Correct the tire pressure and store it in the MMI
=> page 260.

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.

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.

Emergency assistance

@) Note
The compressor must be switched off after six
minutes at the most to reduce the risk of
overheating. Let the compressor cool down
for several minutes before using it again.
G) Tips
The ESC must not be limited or switched off
when driving with the collapsible spare tire
=> page 106.
Jump starting
The vehicle cannot be operated when the 12 Volt
vehicle battery is drained. Your vehicle must not
be jump started in this case. Contact an author-
ized Audi dealer or authorized Audi Service Facili-
ty.
@) Note
The vehicle battery must not be bridged using
conventional jump start methods.

ment are designed specifically for qualified
technicians.
Towing
Teele ela)
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
— The maximum permitted towing speed is 30
mph (50 km/h).
274
— The maximum permitted towing distance is 30
miles (50 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.
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
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
—Ifthe |e} indicator light turns on, there is a
fault in the cooling circuit. The vehicle must
not be towed. The drive system can be se-
verely damaged.
— 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 on a
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.

4KE012721BF
Emergency assistance

— When the parking lock is engaged, neither
the front nor rear axle may be lowered or
raised more than 10. The driveshafts or
tires could be seriously damaged.
— Towing must not be used to charge the
high-voltage battery (recuperation), be-
cause this could result in major damages to
the tow vehicle or the vehicle being towed.
— The vehicle must not be tow started for
technical reasons.
G) Tips
— Switch Audi pre sense* off > page 160 when
loading the vehicle onto a vehicle carrier,
train, ship, or other type of transportation,
or when towing the vehicle. This can prevent
an undesired intervention from the pre
sense* system.
