2009 AUDI S3 relay

Trailer lights
Trailer lights must meet all regulations. Be sure to check with your
authorized Audi dealer for correct wiring, switches and relays.
Mirrors
If you are unable to see the traffic behind you using the regular
outside mirrors, then you
must install extended mirrors. It is impor­
tant that you
always have clear vision to the rear .
& WARNING
After removing the trailer hitch, do not store it in your vehicle. In
case of sudden braking, the hitch could fly forward and injure you
or your passengers .

Operating instructions
Maximum trailer weight
A trailer for your vehicle is limited to a typical class 1 or class 2
trailer.
Trailer load distribution
Be sure the load in the trailer is held securely in place to guard
against shifting, be it forward, backward or sideways.
Never allow a passenger to ride in a trailer:::::, & in "Driving instruc­
tions".
Tire pressure
When towing a trailer, inflate the tires of your vehicle to the cold tire
pressure listed under "Full load" on the sticker on the right door­
jamb. Inflate trailer tires to trailer and tire manufacturers' specifica­
tions.
Controls and equip­ ment Safety first Vehicle operation
Trailer towing
Lights
The
headlight settings should be checked with the trailer attached
before driving off. Adjust as necessary so that you can see the road
ahead but not blind oncoming traffic.
Check proper working of vehicle and trailer lights.
Safety chains
Be sure trailer safety chains are properly connected from the trailer
to the hitch on the vehicle. Leave enough slack in the chains to
permit turning corners. When you install safety chains, make sure
they will not drag on the road when you are driving.
The chains should cross under the trailer tongue to prevent it from
dropping in case of separation from the hitch. •
Driving instructions
Driving with a trailer always requires extra care and
consideration.
To obtain the best possible handling of vehicle and trailer,
please note the following:
Do not tow a loaded trailer when your car itself is not
loaded.
- Be especially careful when passing other vehicles.
Observe speed limits.
Do not drive at the maximum permissible speed.
- Always apply brakes early.
Monitor the temperature gauge.

& WARN ING (continued )
• Before you check anything in the engine compartment , always
read and heed all WARNINGS=>
page 217, "Engine compa rt m ent" .
0 Note
• Applying a higher voltage booster battery wil l cause expensive
damage to sensitive electronic components, such as contro l units,
relays, rad io, etc.
• There must be no electrical contact between the vehicles as
otherwise current cou ld already star t to flow as soon as th e positive
(+ ) termina ls are connected .
• Improperly connected jumper cab les can cause substantia l
damage to the electrica l system of the vehic le.
[ i ] Tips
• The disc harged battery must be p ro per ly connected to the

Start assistance differs for vehicles with a 4-cylinder engine and a 6-
cy lind er eng ine:
=> page 289, "Use of jumper cables (4 cyl inder eng ine)"
=> page 290, "Use of jumper cables (6 cylinder engine)"
& WARNING
Improper handling of the jumper cables can lead to an explosion
of the battery and severe injuries. To reduce the risk of injury , note
the following :
• The sections of the terminal clamps that are not insulated
must not tou ch ea ch other . In addition , the cable clamped to the
battery 's positive terminal must not come in contact with electri ­
cally conne cted parts of the vehicle -danger of short cir cuit!
• Route the jumper cable so that it cannot cat ch in any rotating
parts in the engine compartment .
• Do not bend over the batteries -danger of chemical burns!
• The battery cell locking screws must be tightened securely .
• Keep ignition sources (open flame, burning cigarettes, etc .)
away from the batteries -danger of explosion!
• Do not clamp the minus cable to parts of the fuel system or the
brake lines.
