1.3 Raising Vehicle
WARNING
♦ Before driving the vehicle onto a workshop hoist, make
sure there is enough clearance between any low-lying
components and the hoist.
♦ On the Audi TT's and on the S line vehicles, we recom‐
mend using ramps T 40081 if the lift arms on a vehicle
hoist are too thick to prevent damage.
♦ Before driving a vehicle onto a lifting platform it must be
ensured that the vehicle weight does not exceed the per‐
missible lifting capacity of the platform.
♦ Vehicle may only be lifted at points indicated in illustration
in order to avoid damaging vehicle floor pan and to prevent
vehicle from tipping.
♦ Never start engine and engage a gear with vehicle lifted
so long as even one wheel has contact with the floor!
There is a risk of an accident if this is not observed!
♦ If work is to be performed under vehicle it must be sup‐
ported by suitable stands.
Floor Jack
Always use a suitable rubber or wooden block between the jack
and the vehicle.
A floor jack must be attached only at the mounting points depicted
in the illustration.
Do not lift the vehicle at the engine oil pan, transmission, or on
front or rear axles as serious damage may result.
Hoist and Floor Jack Lifting Points
Front:
On the floor longitudinal reinforcement in the area of the marking.
Rear:
On aluminum case part in front of rear axle mounting point

1.4 Tow Starting/Towing
– Attach tow rope or bar only at following eyes:
Front Towing Eyes
– Open cover.
Screw towing eye in by hand and tighten counter-clockwise using
wheel bolt wrench.

Rear Towing Eye
The rear towing eye is located under the bumper cover on the rear
right.
– Screw towing eye in by hand and tighten counter-clockwise
using wheel bolt wrench.
Tow starting or towing vehicle
Note
♦ Tow-ropes or bars should be attached at above mentioned
points only.
♦ The tow-rope should be able to stretch to reduce the risk of
damage to both vehicles. Therefore only ropes of synthetic
material or rope from similarly flexible material should be used.
However it is safer to use a tow bar!
♦ Avoid excessive towing effort and do not jerk. During towing
operations on unsurfaced roads there is always a danger that
the attachment points will be overstressed and damaged.
♦ Vehicle towing should only be done if it is not possible to start
the engine with the starting assist cable.
If the vehicle must ever tow or be towed, observe the following:
♦ Legal regulations concerning towing must be observed.
♦ Both drivers must be familiar with towing procedures. Inex‐
perienced drivers should not attempt to tow start or tow.
♦ When using a tow rope the driver of the towing vehicle must
engage the clutch very gently when moving off and changing
gear.
♦ The driver of the vehicle being towed must ensure that the tow
rope is always taut.
♦ Both vehicles must have the emergency flasher switched on -
if necessary observe any other regulations.
♦ The ignition must be switched on, so that the steering wheel
is not locked and the turn signals, horn, windshield wipers, and
windshield washer system can be operated.
♦ Since the brake booster only works with the engine running,
the brake pedal must be stepped on with substantially more
force when the engine is switched off.
♦ With the engine switched off, the power steering also does not
work, increasing the amount of steering effort.
♦ Without lubricants in the manual transmission and/or auto‐
matic transmissions the car may only be towed with raised
drive wheels.
Important notes concerning tow starting a vehicle:
It is generally recommended not to tow start vehicles. Instead,
jumper cables should be used.
There are several reasons to not tow start:
♦ During tow starting, the risk of an accident occurring is high,
e.g. driving into vehicle towing.
♦ Vehicles with gasoline engines can be damaged by unburned
fuel entering the catalytic converter.
♦ Tow starting of vehicles with automatic transmission is not
possible for technical reasons.

If a vehicle should be tow started at any time, observe the follow‐
ing:
– Before tow starting, push in clutch pedal and hold, and select
gear 2 or 3.
– Switch ignition on.
– When both vehicles are in motion, release the clutch pedal.
– As soon as the engine is started, push in the clutch and take
the car out of gear to avoid running into the towing vehicle.
Note
Vehicles with catalytic converter (gasoline engine only) must not
be started when the catalytic converter is at operating tempera‐
ture and pulling the vehicle over a longer distance of more than
50 m. Otherwise, the vehicle could be damaged by unburned fuel
entering the catalytic converter.
When towing a vehicle with automatic transmission the following
additional points must be observed:
♦ Selector lever must be in the “N“ position.
♦ Do not tow at speeds greater than 30 mph (50 km/h).
♦ The maximum towing distance is 30 miles (50 km).
For longer distances, the front end of the vehicle must be raised.
Reason: With engine switched off, the transmission oil pump does
not work. Therefore the transmission is not sufficiently lubricated
at higher speeds and longer distances.
When towing with a tow truck, the vehicle may only be towed with
raised front wheels.
Reason: With car raised in the back, the driveshafts turn back‐
wards. This would cause the planetary gears in the automatic
transmission to achieve such high RPM that the transmission
would be heavily damaged within a very short time.
Note
If normal towing of the vehicle is not possible, the vehicle must be
transported with a special transporter or trailer. This also applies
to towing distances of over 30 miles (50 km)
1.5 Vehicle Checks during Inspection and
Maintenance
For vehicle checks, we recommend interactive acceptance VAS
5000 and performance test stand V.A.G 1858.
Brakes, Testing
Information for checking brakes on FWD and AWD vehicles is in
the corresponding brake system repair manual.
Performance Check
Perform performance check on performance test stand recom‐
mended by Audi. The corresponding correction factors for auto‐
matic transmissions and AWD are provided in these test stands.
Vehicles with AWD may only be tested on a four-wheel perform‐
ance test stand.
