Putting on the spare wheel
"'Lift the spare wheel and ca refully slide it
over the alignment pin to guide it in place
¢ (D .
"' Use the hexagonal socket in the screwdriver
handle to screw in and tighten all wheel
bolts
slightly.
"' Remove the alignment pin and insert and
t ighten the remaining wheel bolt s lightly
like the rest .
"'T urn the jack handle counte r-clockw ise to
lower the vehicle unt il the jac k is f ully re­
l eased .
"' Use the whee l bolt wrench to tighten a ll
whee l bolts firmly
¢ page 274. Tighten
them
crosswis e, from one bolt to the (ap­
proximate ly) opposite one, to keep the
wheel cen tered.
When removing or install ing the wheel,
the rim could hit the brake rotor and dam­
age the rotor. Work carefully and have a
second person help you .
{D) Tips
Never use the hexagonal socket in the han­
dle of the screwdriver to loosen or t ighten
the wheel bolts .
- Pull the reversib le blade from the screw­
driver before you use the hexagonal
socket in the handle to turn the whee l
bo lts.
- When mounting tires with
un id ire ctional
tread design
make s ure the tread pat­
tern is poi nted the right way
¢ page 277.
- The wheel bolts should be clean and easy
to tu rn . Check for d irt and corrosion on
the mat ing su rfaces of both the whee l
and the h ub. Remove a ll dir t from these
su rfaces before remo unting the wheel.
What do I do now? 277
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the right direction .
Usi ng a spa re ti re with a tre ad patte rn
intended for use in a specific direction
When using a spare t ire with a tread patter n
intended for use in a spec ific d irection, please
note the following :
- The d irect ion of rotation is marked by an ar­
row on t he side of the ti re .
- If the spare tire has to be installed in the in­
correct direct ion, use the spare tire only
temporarily s ince the t ire will not be able to
achieve its optimum performance cha racte r­
istics w it h regard to aquap la ni ng, no ise and
wear .
- We recommend that you pay part icu lar at­
ten tion to th is fact during we t wea ther and
t ha t you adjust your speed to match road
conditions .
- Replace the fl at t ire wi th a new one and
have i t installed on your vehicle as soon as
possible to restore the hand ling advantages
of a un idirectional tire .
Notes on wheel changing
Please read the information¢ page 257, New
tires and replacing tires and wheels
if you a re
go ing to use a spare tire wh ich is different
from the tires on you r vehicle .
After you change a tire:
- Check the tire pre ssure on the spare imme­
diately after installation.
- Have the wheel bolt tightening torqu e
checked with a torque wrench as soon a s
possible by your authorized Audi dealer or
a qualified service station.
- With steel and alloy wheel rims , the wheel
bolts are cor re ctly tightened at a torque of
90 ft lb (120 Nm ).
- If you notice that the wheel bolts are cor­
roded and diff icult to turn while changing
a tire , they should be replaced before you
check the t ightening torque. .,,.

Starting by pushing or
towing
(D Note
Ve hicles w ith an au tomatic tra nsmission
cannot be started by pus hing o r tow ing.
Starting with jumper
cables
If necessary, the engine can be started by
connecting it to the battery of another vehi­
cle.
If the engine shou ld fail to start because of a
discha rged o r wea k battery, the battery can be
connected to the battery o f
another vehicle,
using a
pair of jumper cables to start the en­
g ine.
Jumper cables
Use only jumper cables of sufficiently la rge
c ross section to carry the starter c urrent safe­
l y. Refer to the man ufacturer's specifications.
Use only jumper cables with
insulated te rm i­
na l clamps wh ic h are d istinctly marked:

284 Emergency situations
@ Tips
The discharged battery must be properly
connected to the vehicle's electrical sys­
tem. When jump starting or charging the
battery, never connect the negative
ground cable to the battery negative post
because the batte ry manager system must
be able to detect the battery 's state of
charge. Always connect the negative
ground cab le to the negative ground post
of the battery manager control unit.
Use of jumper cables
Make sure to connect the jumper cable
clamps in exactly the order described below!
Fig. 218 Engine compartment: connecto rs for jump
start cables and charger
Fig. 219 Jump start ing with the battery of another ve·
hide: @-booster battery, @-discharged ve hicle bat­
tery
The procedure described below fo r connecting
jumper cables is intended to provide a jump
start for your vehicle.
Vehicle with discharged battery:
.,. Turn off lights and accessories, move lever
of automatic transmission to N (Neutral) or
P (Park) and set parking brake.
Connect POSITIVE(+) to POSITIVE(+)
(red)
.,. Open the red cover on the positive terminal
¢fig. 218 .
1. Connect one end of the red positive cable
on the
jump start bolt c::;, fig. 219 @ (bolt
under the red cover = "positive") of the ve­
hicle to be started @.
2. Connect the other end to the positive ter-
mina l@ of the booster battery@.
Connect NEGATIVE (-) to NEGATIVE (-)
(black)
3. Connect one end of the black negative ca­
ble to the negat ive terminal @ of the
booster battery @.
4. Connect the other end to the
jump start
pin © (bolts with hex head bolt= "nega­
tive") of the vehicle to be started @.
Starting the engine
.,. Start the engine of the veh icle w ith the
booster battery@. Run the engine at a
moderate speed .
.,. Start engine with discharged vehicle battery
@ in the usual manner.
.,. If the engine fails to start, do not keep the
starter cranking for longer than 10 seconds.
Wait for about 30 seconds and then try aga in .
.,. With engine running, remove jumper cables
from both vehicles in the exact
reverse o r­
de r .
.,. Close the red cover on the positive term inal.
T he battery is vented to the outside to prevent
gases from entering the veh icle inter ior. Make
sure that the jumper clamps are well connect­
ed with their metal parts in full contact with
the battery terminals.
_& WARNING
To avoid serious personal injury and dam­
age to the vehicle, heed all warnings and
instructions of the jumper cable manufac­
turer. If in doubt, call for road service .
- Jumper cables must be long enough so
that the veh icles do not touch.

(D Note
- The vehicle capacity weight figures apply
when the load is distributed evenly in the
vehicle (passengers and luggage). When
transport ing a heavy load in the luggage
compartment, carry the load as near to
the rear axle as poss ible so that the vehi­
cle's handling is not impaired.
- Do not exceed the maximum permissible axle loads or the maximum gross veh icle
