Emergency assistance

Replacing wheels
Before changing a wheel
Observe the following precautions for your own
and your passenger's safety when changing a
wheel.
>» After you experience a tire failure, pull the car
well away from moving traffic and try to reach
level ground before you stop > A\.
> All passengers should leave the car and move
toa safe location (for instance, behind the
guardrail) > A\.
> Engage the parking brake to prevent your vehi-
cle from rolling unintentionally > A\.
> Move selector lever to position P > /\.
> If you are towing a trailer, unhitch the trailer
from your vehicle.
> Take the jack* > page 348 and the spare tire*
=> page 357 out of the luggage compartment.

ZA\ WARNING
You or your passengers could be injured while
changing a wheel if you do not follow these
safety precautions:
— If you have a flat tire, move a safe distance
off the road. Turn off the engine, turn the
emergency flashers on and use other warn-
ing devices to alert other motorists.
— Make sure that passengers wait in a safe
place away from the vehicle and well away
from the road and traffic.
—To help prevent the vehicle from moving
suddenly and possibly slipping off the jack*,
always fully set the parking brake and block
the front and back of the wheel diagonally
opposite the wheel being changed. When
one front wheel is lifted off the ground,
placing the Automatic Transmission in P
(Park) will not prevent the vehicle from mov-
ing.
— Before you change a wheel, be sure the
ground is level and firm. If necessary, use a
sturdy board under the jack”.
— Always store the vehicle tool kit, the jack*
and the replaced tire in the luggage com-
partment > page 60.

Always read and follow all WARNINGS and in-
formation > A\ in Raising the vehicle on
page 355 and > page 356.
After changing a wheel
A wheel change is not complete without the do-
ing the following.


> Always store the vehicle tool kit, the jack* and
the replaced tire in the luggage compartment
=> page 60.
> Check the tire pressure on the spare wheel im-
mediately after mounting it.
> As soon as possible, have the tightening tor-
ques on all wheel bolts checked with a torque
wrench. The correct tightening torque is
90 ft lb (120 Nm).
> Have the flat tire replaced as soon as possible.

Emergency assistance

Loosening
> Slide the wheel wrench onto the wheel bolt as
far as it will go.
> Take tight hold of the end of the wrench handle
and turn the wheel bolts counter-clockwise
about one single turn in the direction of arrow
> fig. 270.
Tightening
> Slide the wheel wrench onto the wheel bolt as
far as it will go.
> Take tight hold of the end of the wrench handle
and turn each wheel bolt clockwise until it is
seated.

Z\ WARNING
— Do not use force or hurry when changing a
wheel - you can cause the vehicle to slip off
the jack* and cause serious personal injuries.
— Do not loosen the wheel bolts more than
one turn before you raise the vehicle with
the jack*. - You risk an injury.

@® Tips
— Never use the hexagonal socket in the han-
dle of the screwdriver to loosen or tighten
the wheel bolts.
— If a wheel bolt is very tight, you may find it
easier to loosen by carefully pushing down
on the end of the wheel bolt wrench with
one foot only. As you do so, hold on to the
car to keep your balance and take care not
to slip.

handle to completely remove the topmost
wheel bolt and set it aside on a clean surface
> fig. 273.
> Screw the threaded end of the alignment pin
from the tool kit hand-tight into the empty bolt
hole > fig. 274.
> Then remove the other wheel bolts as described
above.
> Take off the wheel leaving the alignment pin in
the bolt hole >@).
Putting on the compact spare wheel
> Lift the spare wheel and carefully slide it over
the alignment pin to guide it in place >@.
> Use the hexagonal socket in the screwdriver
handle to screw in and tighten all wheel bolts
slightly.
> Remove the alignment pin and insert and tight-
en the remaining wheel bolt slightly like the
rest.
> Turn the jack handle counter-clockwise to lower
the vehicle until the jack* is fully released.
> Use the wheel bolt wrench to tighten all wheel
bolts firmly > page 353. Tighten them cross-
wise, from one bolt to the (approximately) op-
posite one, to keep the wheel centered.
@) 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.
G) Tips
Never use the hexagonal socket in the handle
of the screwdriver to loosen or tighten the
wheel bolts.
— Pull the reversible blade from the screwdriv:
er before you use the hexagonal socket in
the handle to turn the wheel bolts.
— When mounting tires with unidirectional
tread design make sure the tread pattern is
pointed the right way > page 356.
— The wheel bolts should be clean and easy to
turn. Check for dirt and corrosion on the
356
mating surfaces of both the wheel and the
hub. Remove all dirt from these surfaces be-
fore remounting the wheel.
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the
right direction.
Using a spare tire with a tread pattern
intended for use in a specific direction
When using a spare tire with a tread pattern in-
tended for use in a specific direction, please note
the following:
— The direction of rotation is marked by an arrow
on the side of the tire.
— If the spare tire has to be installed in the incor-
rect direction, use the spare tire only tempora-
rily since the tire will not be able to achieve its
optimum performance characteristics with re-
gard to aquaplaning, noise and wear.
— We recommend that you pay particular atten-
tion to this fact during wet weather and that
you
adjust your speed to match road condi-
tions.
— Replace the flat tire with a new one and have it
installed on your vehicle as soon as possible to
restore the handling advantages of a unidirec-
tional tire.
Notes on wheel changing
Please read the information > page 326 if you
are going to use a spare tire which is different
from the tires on your vehicle.
After you change a tire:
— Check the tire pressure on the spare immedi-
ately after installation.
— Have the wheel bolt tightening torque
checked with a torque wrench as soon as pos-
sible by your authorized Audi dealer ora
qualified service station.
— With steel and alloy wheel rims, the wheel
bolts are correctly tightened at a torque of
90 ft lbs (120 Nm).

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.

ZX WARNING
— After installing a spare tire, the tire pressure
must be checked as soon as possible. The
tire pressure is available on > page 330,
fig. 260
— Do not drive faster than 50 mph (80 km/h)
with a compact spare tire. Driving faster

Emergency situations


such as the engine block or transmission
are removed.
— When removing heavy components like
these, anchor vehicle to hoist or add corre-
sponding weights to maintain the center of
gravity. Otherwise, the vehicle might tilt or
slip
off the hoist, causing serious personal
injury.

@ Note
— Be aware of the following points before Lift-
ing the vehicle:
— The vehicle should never be lifted or
jacked up from underneath the engine oil
pan, the transmission housing, the front
or rear axle or the body side members.
This could lead to serious damage.
—To avoid damage to the underbody or
chassis frame, a rubber pad must be in-
serted between the floor jack and the lift
points.
— Before driving over a workshop hoist,
check that the vehicle weight does not
exceed the permissible lifting capacity of
the hoist.
— Before driving over a workshop hoist, en-
sure that there is sufficient clearance be-
tween the hoist and low parts of the ve-
hicle.
