rotor. Work carefully and have a second per­
son help you.
(D Tips
- When mounting tires with unidirectional
tread design
make sure the tread pattern is
pointed the right way
¢ page 278.
-The wheel bolts should be clean and easy to
turn. Check for dirt and corrosion on the mating surfaces of both the wheel and the
hub. Remove all dirt from these surfaces be­
fore remounting the wheel.
Unidirectional tires
A unidirectional tire profile is identified by arrows
that point in the running direction on the tire
sidewall. You must always adhere to the speci­
fied running direction. This is necessary ensure
the tire 's optimum performance in regard to ad­
hesion, running noise, friction and 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.
Finishing
.,. Reinstall the caps on the wheel bolts if neces­
sary .
.,. 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 183.
.,. Check the tire pressure on the installed wheel
as soon as possible.
.,. Check the tire pressure and store it in the Info­
tainment system.
.,. The wheel bol t tightening specification must be
90 ft lbs (120 Nm) . Check it as soon as possible
with a torque wrench. Drive carefully until then.
.,. Have the faulty wheel replaced as quickly as
possible.
278
(D Tips
- If you notice that the wheel bolts are cor­
roded and difficult to turn while changing a
tire, they should be replaced before you check the tightening torque.
- Drive at reduced speed until you have the
tightening torques checked.
Notes on wheel changing
Please read the information ¢ page 251 if you
are going to use a spare tire which is different
from the tires on your vehicle .

Emergency situations
General
This chapter is intended for trained emergency
crews and working personnel who have the nec­
essary tools and equipment to perform these
operations.
Starting by pushing or
towing
~ Note
Vehicles with an automatic transmission can­
not be started by pushing or towing.
Starting with jumper
cables
If necessary, the engine can be started by con­
necting it to the battery of another vehicle .
If the engine should fail to start because of a dis­
charged or weak battery, the battery can be con­
nected to the battery of
another vehicle, using a
pair of jumper cables to start the engine.
Jumper cables
Use only jumper cables of sufficiently large cross
section
to carry the starter current safely. Refer
to the manufacturer's specifications.
Use only jumper cables with
insulated terminal
clamps which are distinctly marked :
plus(+) cable in most cases colored red
minus(-) cable
in most cases colored black.
A WARNING -
Batteries contain electricity, acid, and gas.
Any of these can cause very serious or fatal in­
jury. Follow the instructions below for safe
handling of your vehicle's battery .
-Always shield your eyes and avoid leaning
over the battery whenever possible.
-A dead battery can freeze at temperatures
around 32 °F (0 °C) . If the vehicle battery is
frozen, you must thaw it before connecting
the jump start cables. If you do not, this in-
Emergency situations
creases the risk of an explosion and chemi­
cal burns. After jump starting the vehicle,
drive to an authorized Audi dealer or author­ ized Audi Service Facility immediately to
have the vehicle battery checked.
- Do not allow battery acid to contact eyes or
skin . Flush any contacted area with water
immediately.
- Improper use of a booster battery to start a
vehicle may cause an explosion .
- Vehicle batteries generate explosive gases .
Keep sparks, flame and lighted cigarettes
away from batteries.
- Do not try to jump start any vehicle with a
low acid level in the battery .
- The voltage of the booster battery must also
have a 12-Volt rating . The capacity (Ah) of
the booster battery should not be lower
than that of the discharged battery. Use of
batteries of different voltage or substantial­
ly different "Ah " rating may cause an explo­
sion and personal injury.
- Never charge a frozen battery. Gas trapped
in the ice may cause an explosion.
- Never charge or use a battery that has been
frozen. The battery case may have be weak­
ened.
- Use of batteries of different voltage or sub­
stantially different capacity (Ah) rating may
cause an explosion and injury. The capacity
(Ah) of the booster battery should not be
lower than that of the discharged battery.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS
c>page 233.
@ Note
- Applying a higher voltage booster battery
will cause expensive damage to sensitive
electronic components, such as control
units, relays, radio, etc.
- There must be no electrical contact between
the vehicles as otherwise current could al­
ready start to flow as soon as the positive
( + ) terminals are connected.
283

Emergency situations
@ Tips
The discharged battery must be properly con·
nected to the vehicle's electrical system .
When jump starting or charging the battery,
never connect the negative ground cable to
the battery negative post because the battery
manager system must be able to detect the
battery's state of charge. Always connect the
negat ive g round cable to the negative ground
post of the battery manager control unit.
Using the jump start
cable
Both jump start cables must be connected in the
correct order!
