tire failure and lo ss of vehicle control.
• If you noti ce unusual vibration or if the vehicle pulls to one side
when driving , always stop as soon as it is safe to do so and check
the wheels and tires for damage . •

& WARNING (continued)
-if you have been driving with very low tire pressures or tires
with no air
• Seek professional assistance if it is not possible to repair the
tire with the tire sealant.
& WARNING
The tire sealant must not come into contact with skin, eyes or
clothing.
• If you get any tire sealant
in your eyes or come into contact

- Do not induce vomiting! Find a physician immediately!
• If you have allergic reactions, find a physician immediately .
• Keep the tire sealant away from children .
0 Note
Do not use commercially available tire sealants. The electrical
components of the tire pressure monitoring system will no longer
work properly.
'i> For the sake of the environment
Used sealant bottles can be dropped off at a recycling facility.
[ i] Tips
• If sealant has run out, allow it to dry. Then you can peel it off.
• Have the tire sealant replaced every 4 years at a dealership. •

• Before you check anything in the engine compartment, always
read and heed all WARNINGS~ page 212, "Engine compartment".
0 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 already start to flow as soon as the positive
(+) terminals are connected.
[ i) Tips
The discharged battery must be properly connected to the vehicle's
electrical system. •
Use of jumper cables
Make sure to connect the jumper cable clamps in exactly
the order described below!
Fig. 182 For jump
starting or charging
the battery, there is a
jump start connection
on the left side of the
engine compartment . Fig. 183 Jump

On vehicles with the 6-cylinder engine, instead of the
battery, on the left side of the engine compartment there is
a
Jump start connection=:> fig. 182. For jump starting, open
the cover on the positive terminal.
Preparatory measures
1. Do not jump start a frozen battery! Replace such a
battery!
2. Otherwise apply the hand brake and shift into idle gear if
your vehicle has manual transmission, and put the
selector lever into P position if your vehicle has auto ­
matic transmission.
3. For both vehicles switch off all consumers and the igni­
tion.

Emergency towing with commercial
tow truck
General hints
Your Audi requires special handling for towing.
The following information is to be used by commercial tow truck
operators who know how to operate their equipment safely.
• Never tow your Audi, towing will cause damage to the engine
and transmission.
• Never wrap the safety chains or winch cables around the brake
lines.
• To prevent unnecessary damage, your Audi must be transported
with a car carrier (flatbed truck).
• To load the vehicle on to the flat bed, use the towing loop found
in the vehicle tools and attach to the front or rear anchorage
=> page 281 and=> page 282.
& WARNING
A vehicle being towed is not safe for passengers. Never allow
anyone to ride in a vehicle being towed, for any reason. •
Front towing loop
Do not install the front towing loop until it is needed.

- Remove the screwdriver and towing loop from the
vehicle toolkit=>
page 262.
-Insert the screwdriver into the slot as shown and press
toward the center of the vehicle => fig. 184. At the same
time, pull the grill forward and out.

& WARNING
• To reduce the risk of serious injury and vehicle damage .
- Always lift the vehicle only at the special workshop hoist and
floor jack lift points illustrated
~ page 283, fig. 188 and
~ page 283, fig. 189.
- Failure to lift the vehicle at these points could cause the
vehicle to tilt or fall from a lift if there is a change in vehicle
weight distribution and balance. This might happen, for
example, when heavy components such as the engine block or
transmission are removed.
• When removing heavy components like these, anchor vehicle
to hoist or add corresponding weights to maintain the center of
gravity. Otherwise, the vehicle might tilt or slip off the hoist,
causing serious personal injury.
0 Note
• Be aware of the following points before lifting the vehicle:
- The vehicle should never be lifted or jacked up from under­
neath 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 inserted 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, ensure that there is sufficient clearance between the hoist and low parts of the
vehicle. •

& W
ARNING (continued )
• Do not attempt any of the maintenance , checks or repairs
described on the following pages if you are not fully familiar with
these or other pro cedures with respect to the vehicle , or are uncer­
tain how to proceed.
• Do not do any work without the proper tools and equipment.
Have the necessary work done by your autho rized Audi dealer or
another properly equipped and qualified workshop .
• The engine compartment of any motor vehicle is a potentially
hazardous area . Never reach into the area around or touch the
radiator fan . It i s temperature controlled and can switch on
suddenly -even when the engine is off and the ignition key has
been removed . The radiator fan switche s on automatically when
the coolant reaches a certain tempe rature and will continue to run
until the coolant temperature drops .
• Always remove the ignition key before anyone gets under the
vehicle.
• Always support your vehicle with safety stands if it is neces­
sary to work underneath the vehicle. The jack supplied with the
vehicle is not adequate for this purpose and could collapse
causing serious personal injury .
• If you must work underneath the vehicle with the wheels on
the ground, always make sure the vehicle is on level ground , that
the wheels are always securely blocked and that the engine
cannot be started .
• Always make sure the transmission selector lever (automatic
transmission) is in "P" (Park position ) (automatic transmission ) or
Neutral (manual tr ansm ission) and the hand brake is firmly
applied.
• Chang ing t he e ngine sett ings wi ll a dverse ly affect em ission
levels. This is detrimenta l to the environment and increases fuel
co nsu mp tion.
