be five 150 lbs. passengers in
your vehicle, the amount of
available cargo and luggage
load capacity is 650 lbs.
(1400-750 (5 x 150) = 650
lbs.)
5. Determine the combined
weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely ex-
ceed the available cargo and
luggage load capacity calculat-
ed in Step 4.
6. If your vehicle will be towing a
trailer, load from your trailer
will be transferred to your vehi-
cle. Consult this manual to de-
termine how this reduces the
available cargo and luggage
load capacity of your vehicle.
> Check the tire sidewall
(> page 275, fig. 170) to deter-
mine the designated load rating
for a specific tire.
Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/tighten
easily.
Rims
Rims with a bolted rim ring* or with bolted wheel
covers* consist of multiple pieces. These compo-
nents were bolted together using special bolts
and a special procedure. You must not repair or
disassemble them > A\.

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 > page 311, 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 fi 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 311, Finishing.
fi 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. >

the left. To achieve the required torque, hold
the end of the wheel wrench*. If the wheel bolt
will not loosen, press carefully on the wheel
wrench* with your foot. Hold onto the vehicle
securely while doing this and make sure your
footing is stable.

ZA WARNING
To reduce the risk of an accident, only loosen
the wheel bolts gently one turn before raising
the vehicle with the vehicle jack*.
Raising the vehicle
Applies to: vehicles with vehicle jack







Fig. 183 Sill: positioning the vehicle jack
> Place the vehicle jack from the vehicle tool kit
ona firm surface. Use a flat, stable support if
necessary. On a slippery surface such as tile,
you should use a non-slip pad such as a rubber
mat > /\.

D_ You need the matching adapter in order to loosen and
tighten anti-theft wheel bolts* > page 308.
> Find the marking on the sill that is closest to
the tire that will be changed © fig. 182. Behind
the marking, there is a lifting point on the side
sill for the vehicle jack.
> Raise the vehicle jack under the lifting point on
the side sill until the bracket on the jack @)
completely covers the notch on the vehicle.
> Align the vehicle jack so the bracket (@) covers
the notch and the base (2) is flat on the ground.
The base @) must be directly under the mount-
ing point @.
> Mount the crank on the vehicle jack: insert the
crank into the opening on the handwheel. Turn
the crank to the left or right to secure it.
> Continue raising the vehicle jack with the crank
until the wheel lifts off the ground slightly.


ZX WARNING
—To reduce the risk of injury, make sure no
one is in the vehicle before raising it.
— Make sure the vehicle jack is stable. The risk
of injury is increased when the ground is
slippery or soft, because the vehicle jack
could slide or sink.
— Only raise your vehicle with the vehicle jack
provided by the factory. If you use a vehicle
jack designed for another vehicle, your vehi-
cle could slip and cause injury.
— Position the vehicle jack only at the desig-
nated mounting points on the side sill and
align the jack. Otherwise, the vehicle jack
could slip and cause an injury if it does not
have sufficient hold on the vehicle.
—To reduce the risk of injury, do not raise any
other vehicles or other loads using the vehi-
cle jack provided by the factory.
— Applies to: vehicles with air suspension:
Changes in temperature or load can affect
the height of the stopped vehicle.
— To reduce the risk of an accident, never start
the engine when the vehicle is raised.
—To reduce the risk of injury, no work should
be performed under the vehicle while it is

raised.

rotor. Work carefully and have a second per-
son help you.
Ue lieraeCelar | mae}
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.

4K8012721BF
Emergency assistance

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 83.
> Check the tire pressure on the installed wheel
as soon as possible.
> Correct the tire pressure and store it in the MMI
=> page 293 or > page 296.
> The wheel bolt tightening specification must be
90 ft lbs (120 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.
Space-saving spare tire
Applies to: vehicles with space-saving spare tire (compact
spare tire)
The spare tire is intended for short-term use only.
Have the damaged tire checked and replaced if
necessary by an authorized Audi dealer or author-
ized Audi Service Facility as soon as possible.
There are some restrictions on the use of the
compact spare tire. The compact spare tire has
been designed specifically for your type of vehi-
cle. Do not replace it with the spare tire from an-
other type of vehicle.
The compact spare tire is located in the luggage
compartment under the cargo floor cover
=> page 305.
The tire pressure must be adjusted to a specified
value listed on the tire pressure sticker
= page 284, fig. 173.
Snow chains
For technical reasons, the use of snow chains on
the compact spare tire is not permitted.
If you have to drive with snow chains and a front
tire fails, mount the spare tire in place of a rear
tire. Install the snow chains on the rear tire that
you removed, and install that in place of the
front tire that failed.

ZA WARNING
— After installing a spare tire, the tire pressure
must be checked as soon as possible.
— Do not drive faster than 50 mph (80 km/h)
with a compact 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 compact spare tire.
— To reduce the risk of an accident, never drive
with more than one compact spare tire.
— Normal summer or winter tires must not be
mounted on the compact spare wheel rim.

Jump starting
You should only perform the steps that follow if
you have the necessary tools and technical ex-
pertise.
If the engine does not start because the vehicle
battery is drained, you can jump start your vehi-
cle using another vehicle. Jump start cables are
needed to do this.
Both vehicle batteries must have 12 V nominal
voltage. The voltage capacity (Ah) of the vehicle
battery that is giving power must not be less
than the capacity of the drained vehicle battery.
Jump start cable
Only use a jump start cable with a large enough
diameter. Note the manufacturer's specifica-
tions.
Only use a jump start cable with insulated termi-
nal clamps.
Positive cable - usually red.
Negative cable - usually black.
