A WARNING
When using the vehicle jack* on a road with a
steep hill or offroad, you must take extra pre­
cautions to prevent the vehicle from rolling .
Use suitab le objects to b lock the front and
back of the wheel that is diagonal from the
wheel with the flat tire.
A WARNING
You or your passengers could be in ju red wh ile
chang ing a wheel if you do not follow these
safety precautions :
Emergen cy a ssis tanc e
-If you have a flat tire, move a safe distance
off the road. Turn off the eng ine, turn the
emergency flashers on and use other warn­
ing dev ices to alert other motorists .
- Make sure that passengers wait in a safe
place away from the vehicle and well away
from the road and traff ic .
- To help prevent the veh icle from moving
suddenly a nd possib ly slipping off the jack*,
always fully set the park ing brake and block
the front and back of the wheel diagonally opposite the wheel being changed. When
one front wheel is lif ted off the gro und,
p la cing the Automa tic Transmission in P

Emergency assistance
Loosening the wheel bolts
Fig. 284 Wheel: loosening the wheel bolt
• Slide the wheel wrench (from the vehicle tool
kit) all the way onto the wheel bolt.
• Turn the wheel bolt approximately one turn to
the left -arrow-. To reach the required torque,
hold the end of the wheel wrench. If the wheel
bolt will not loosen, press carefully on the
whee l wrench with your foot. Hold onto the ve­
hicle securely while during this and make sure
your stance is stable .
A WARNING
To reduce the risk of an accident, only loosen
the wheel bolts gently (one turn) before rais­
ing the vehicle with the veh icle jack*.
Raising the vehicle
Fig . 28S Sill panels: markings
364
Fig. 286 Sill: positio ning the vehicle jack
• Place the veh icle jack* (vehicle tool kit) on a
firm s urface. Use a flat, stable support if neces­
sary. On a slippery surface such as tile, you
should use a non-slip pad (such as a rubber
mat)¢ &.
• Find the marking on the sill that is closest to
the tire that will be
changed¢ fig. 2 85 . Behind
the marking, there is a lifting point on the side
sill for the vehicle jack*.
• Turn the handwheel to raise the vehicle jack*
under the lifting point on the side sill until the
bracket on the jack @ completely covers the
notch on your vehicle.
• Align the vehicle jack* so the bracket @covers
the notch and the base ® is flat on the ground.
The base ® must be directly under the lifting
point @.
• Mount the crank on the vehicle jac k*: insert the
crank into the opening on the handwheel. Turn
the crank to the left or right to secure it.
• Continue ra is in g the veh icle jack* with the
crank until the wheel lifts off the ground slight­
ly.
A WARNING
- Ma ke sure the vehicle jack* is stable. Th ere
is a risk of injury when the ground is slick 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 can slide 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 an accident, never start
the engine when the vehicle is raised.
- To reduce the risk of injury, support the ve­
hicle securely with suitable stands if work is
to be performed underneath the vehicle.
- To help prevent injury to yourself and your
passengers:
- Do not raise the vehicle until you are sure the jack* is securely engaged.
- Passengers must not remain in the vehicle when it is jacked up.
- Make sure that passengers wait in a safe
place away from the vehicle and well away
from the road and traffic.
- Make sure jack position is correct, adjust as necessary and then continue to raise
the jack*.
- If work has to be done under the vehicle, ensure that it is safely supported on suita­
ble stands
-risk of injury!
- Never start the engine when the vehicle is on the jack*
-risk of accident!
(D Note
Do not lift the vehicle by the sill. Position the
vehicle jack* only at the designated mounting points on the side sill. Otherwise, your vehicle
will be damaged.

th e hex socket.
.,. Remove the alignment pin and also tighten the
remai ning wheel bolt.
.,. Carefully lower the vehicle using the vehicle
jack*.
.,. Tighten the wheel bolts in a diagonal pattern
using the wheel wrench .
The wheel bolts must be clean and loosen/tight­
en easily. Check the contact surfaces for the
wheel and hub . Contaminants on these surfaces
must be removed before installing the wheel.
A WARNING
Never use the hex socket in the screwdriver
handle or the hex socket wrench with the
ratchet to loosen or tighten the wheel bolts.
This increases the risk of an accident, because
you will not reach the tightening specification
required .

After you change a tire:
- Check the tire pressure on the replacement
tire immediately after installation.
- Have the wheel bolt tightening torque
checked with a torque wrench as soon as pos­
sible by your authorized Audi dealer or quali­
fied workshop.
- With steel and alloy wheel rims, the wheel
bolts are cor rectly tightened at a torque of
90
ft lbs (120 Nm) .
- If you notice that the wheel bolts are corroded
and difficult to turn while changing a tire,
they should be replaced before you check the

Space-saving spare tire
App lies to: ve hicles with space-saving spare t ire (co mpact
spare tire)
The spare tire is intended for short -term use on ­
ly. Have the damaged tire checked and replaced,
if necessary, by an authorized Audi dealer or au­
thorized 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 f loor cover
c::>page360.
The tire pressure must be 61 PSI (420 kPA).
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 t ire in place of a rear
tire. Install the snow chains on the rear tire that
you removed, and insta ll that in place of the
front tire that failed.
A WARNING
-After installing a spare tire, the tire pres­
sure 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.
