ESP AUDI A5 2008 8T / 1.G Repair Manual

Accessories and modifications to the vehicle 250Accessories and modifications to the vehicleAccessories and replacement partsAlways ask your dealer or specialist retailer for advice
before purchasing accessories and replacement parts.Your car is designed to offer a high standard of active and passive
safety. For this reason, we recommend that you ask an Audi dealer
for advice before fitting accessories or replacement parts. Audi
dealers have the latest information from the manufacturer and can
recommend accessories and replacement parts which are suitable
for your requirements. They can also answer any questions you
might have regarding official regulations.
We recommend you to use only Audi accessories and Audi Genuine
parts
®. Audi has tested these parts and accessories for suitability,
reliability and safety. Audi dealers have the necessary experience
and facilities to ensure that the parts are installed properly.
Although the market is constantly scrutinised, Audi cannot judge or
assume responsibility for the reliability, safety and suitability of
non-genuine products - even though in some instances, these parts
may have been approved by an officially recognised technical
testing authority or accompanied by an official approval certificate.
Any retro-fitted equipment which has a direct effect on the vehicle
and/or the way it is driven (e.g. cruise control system or electroni-
cally-controlled suspension) must be approved for use in your
vehicle and bear the e mark (the European Union's approval
symbol).
If any additional electrical components are fitted which do not serve
to control the vehicle itself (for instance a refrigerator box, laptop or
ventilator fan, etc.), these must bear the CE mark (manufacturer
conformity declaration in the European Union).
WARNING
Never attach accessories (such as cup holders or telephone
brackets) to the surfaces covering the airbag units or the areas
around the airbags: this could cause injury if the airbag is
triggered.ModificationsModifications must always be carried out according to
our specifications.Unauthorised modifications to the electronic components or soft-
ware in the vehicle may cause malfunctioning. Due to the way the
electronic components are linked together in networks, other
systems may be affected by the faults. This can seriously impair
safety, lead to excessive wear of components, and also invalidate
the type approval for your vehicle.
You will appreciate that your Audi dealer cannot be held liable for
any damage caused by modifications and/or work performed incor-
rectly.
We recommend that all work should be performed by an Audi work-
shop using Audi Genuine parts
®.
WARNING
Incorrectly performed modifications or other work on your vehicle
can lead to malfunctions and cause accidents.

Self-help 266Starting the engine
The two jump leads must be connected in the correct
sequence.The jump-start terminals are located in the engine compart-
ment ⇒fig. 248.
Connecting the positive terminals with the
positive lead (red)
– Open the red cap on the positive terminal ⇒fig. 248.
1. Connect one end of the lead to the jump-start terminal
⇒fig. 249 (terminal under red cap = “positive”) of the
vehicle with the flat battery .2. Connect the other end of the positive lead to the positive
terminal of the boosting battery .
Connecting negative terminals with the
negative lead (black)
3. Connect one end of the negative lead to the negative
terminal of the boosting battery .
4. Connect the other end of the lead to the jump-start
terminal (terminal with hexagon = “negative”) of the
vehicle with the flat battery .
Starting the engine
– Start the engine of the vehicle with the boosting battery
and let it run at idling speed.
– Now start the engine of the vehicle with the discharged
battery .
– If the engine fails to start: do not operate the starter for
longer than 10 seconds. Wait for about 30 seconds and
try again.
– When the engine is running, disconnect the leads in
exactly the opposite sequence to that described above.
– Refit the red cap onto the positive terminal.
The battery is vented to the outside to prevent gases entering the
vehicle's interior.
Connect the battery clamps so they have good metal-to-metal
contact with the respective terminals.
WARNING
•
The non-insulated parts of the battery clamps must not be
allowed to touch. The jump lead attached to the positive battery

Technical data terminal must not touch metal parts of the vehicle: this can cause
short circuiting.
•
Do not bend over the batteries – risk of acid burns.
•
The screw plugs on the battery cells must be screwed in firmly.
•
Keep sparks, flame and lighted cigarettes away from batteries:
the gases given off can cause an explosion.
•
If jump-starting another vehicle, position the jump leads in
such a way that they cannot come into contact with any moving
parts in the engine compartment of the other vehicle.Caution
Please note that the above method of connecting the leads is meant
for jump-starting your vehicle. If jump-starting another vehicle, you
should not connect the negative lead (–) to the negative terminal of
the discharged battery, but directly to the engine block or a solid
metal part bolted to the engine block. If the battery of the other
vehicle does not have a gas vent, there is a risk that a mixture of
oxygen and hydrogen gas can accumulate and cause an
explosion.Tow-starting and towing awayGeneral notes
Points to observe when tow-starting or towing awayIf you use a towrope:
Notes for the driver of the towing vehicle
– The towrope must be taut before driving off.– Engage the clutch very gently when starting to move; on
vehicles with automatic gearbox press the accelerator
slowly.
Notes for the driver of the towed vehicle
– The ignition should be switched on so that the turn
signals, horn, windscreen wipers and washers can be
used. Please ensure that the steering wheel is unlocked
when you switch on the ignition, and that it moves freely.
–Put gear lever in neutral (manual gearbox) or move
selector lever to position N (automatic gearbox).
– The brake servo and power steering only work when the
engine is running. Considerably more effort is required
on the brake pedal and steering wheel when the engine
is switched off.
– Ensure that the towrope remains taut at all times when
towing.
Towrope or towbar
It is easier and safer to tow a vehicle with a towbar. You should only
use a towrope if you do not have a towbar.
A towrope should be slightly elastic to reduce the loading on both
vehicles. It is advisable to use a towrope made of synthetic fibre or
similar material.
Attach the tow-rope or tow-bar only to the towing anchorages
intended for this purpose ⇒page 268 or ⇒page 269.
Driving technique
Towing requires some experience – especially when using a
towrope. Both drivers should be familiar with the technique required
for towing. Inexperienced drivers should not attempt to tow-start or
tow away another vehicle.

WARNING
•
Take particular care when working on components in the
engine compartment if the engine is warm - risk of burns!
•
Bulbs are sensitive to pressure. The glass can break when you
touch the bulb, causing injury.
•
Incorrect handling of the high-voltage element of xenon gas-
discharge bulbs* can have potentially fatal consequences.
•
When changing bulbs, please take care not to injure yourself on
sharp edges, in particular on the headlight housing.Caution
•
Always remove the ignition key before carrying out any work on
the electrical system - danger of short circuiting!
•
Switch off the lights or parking lights before you change a bulb.
•
Take good care to avoid damaging any components.
•
Removing the lights in particular can lead to the paintwork
becoming damaged. This is another reason why we recommend
having the bulbs changed by a qualified workshop.For the sake of the environment
Please ask your specialist retailer how to dispose of used bulbs in
the proper manner.
Note
Place the parts you have removed on a soft cloth so that they do not
become scratched.
•
Please check at regular intervals that all lighting (especially the
exterior lighting) on your vehicle is functioning properly. This is not
only in the interest of your own safety, but also in that of all other
road users.
•
Before changing a bulb, make sure you have the correct new
bulb.
•
Do not touch the glass part of the bulb with your bare hands, use
a cloth or paper towel instead. Otherwise, the fingerprints left on
the glass will vaporise as a result of the heat generated by the bulb,
be deposited on the reflector and impair its surface.
Bulbs with a bayonet fastenerBulbs with a bayonet fastener must be changed as follows:
Removing the bulb
– Lightly press the defective bulb into the bulb holder, then
turn it anti-clockwise and remove it.
– Do not touch the glass part of the new bulb with your
bare hands, use a cloth or paper towel instead.
Fitting the bulb
– Fit the new bulb, pressing it into the bulb holder, and turn
it clockwise as far as it will go.
– If necessary, use a cloth to remove any fingerprints from
the glass part of the bulb.
