2008 AUDI A4 AVANT instrument cluster

& WARNING
Changing the vehicle's suspension including use of unapproved
tire-rim combinations can change Advanced Airbag performance and increase the risk of serious personal injury in a crash.
• Never install suspension components that do not have the
same performance characteristics as the components originally
installed on your vehicle.
• Never use tire-rim combinations that have not been approved
by Audi.
& WARNING
Items stored between the safety belt buckle and the center
console can cause the sensors in the buckle to send the wrong
information to the electronic control module and prevent the
Advanced Airbag System from working properly .
• Always make sure that nothing can interfere with the safety
belt buckles and that they are not obstructed . •
Safety first
Airbag system
Side airbags
Description of side airbags
The airbag system can provide supplemental protection
to properly restrained occupants.
Fig. 181 Side airbag
location in the driver's
seat
The side airbags are located in the sides of the front seat backrests
=> fig. 181 and the rear backrest* facing the doors. They are identi­
fied by the word "AIRBAG".
The side airbag system basically consists of: • the electronic control module and external side impact sensors
• the two side airbags located in the sides of the front backrests
• two rear side airbags (as an ordered
option)
• the airbag warning light in the instrument cluster .
Th e airbag system is monitored electronically to make certain that
it is functioning properly at all times. Each time you turn on the igni­
tion, the airbag system indicator light will come on for a few
seconds (self diagnostics).
The side airbag system supplements the safety belts and can help
to reduce the risk of injury to the driver's, front and rear*

W eig ht d is tri buti on
Towing a loaded tra iler wit h an empty car resu lts in a high ly
unstable distribution of weight . If this cannot be avoided drive at
ve ry low speeds only to avo id the risk of losing steering control.
A "ba lanced" rig is easier to operate and control. This means that
the tow vehicle should be loaded to the extent possible and permis ­
sib le whi le keeping the trailer as light as possib le under the circum ­
stances. Whenever possible, transfer some cargo to the luggage
compar tment of the tow veh icle whi le observi ng tongue load
requirements and vehicle loading considerations.
Speed
T he higher the speed, the more difficu lt it becomes for the driver to
contro l the rig . Do not drive at the maximum permissible speed.
Reduce your speed even more under unfavorable load, weather or
wind conditions -part icularly when going dow nh ill.
Reduce vehicle speed
immedi ately if the trailer shows the slightest
sign of swaying.
Do not tr y to stop the s waying by a cceler ating .
Observe speed limits . In some areas speeds for veh ic les towi ng
trai lers are lower than for regular vehicles.
Always app ly brakes early. When driving downhi ll, shift into lower
gear to use the engine braking effect to slow down the vehicle. Use
of the brakes alone can cause them to overheat and fail.
C oo la nt tempe ra tu re
The coola nt temperature gauge => page 13 must be observed care ­
ful ly. If the needle moves close to the upper end of the scale, reduce
speed immediately and/or switch off the air conditioner.
If the coolant te mperature warning light in the instrument cluster
starts
flashing -~-, pul l off the road, stop and let the engine idle for
about two minutes to prevent heat build -up .
& WARNING
An yone not p rop erl y res trained in a mo ving vehicl e is at a much
gre ate r risk in an accident. Never let an yone rid e in your car who
is not p rop erl y wear ing the re stra int s pro vided b y Aud i. •
Trailer towing tips
Important to know
Your vehicle handles differently when towing a tra iler because of
the additional weight and weight distribution. Safety, performance
and economy wi ll great ly depend on how carefu lly you load your
trai ler and operate your rig.
Before you actual ly tow your tra iler, practice turning, stoppi ng and
backing up in an area away from traffic. Keep practicing unti l you
have comp letely become familiar with the way yo ur vehicle -trailer
combination behaves and responds .
Backing up is difficu lt and requires practice. Backing up with a
trai ler genera lly requ ires steering action oppos ite of that when
backing up your vehic le without a trailer.
Mainta in a greater distance between you r vehic le and the one in
front of you. You will need more room to stop.
To compensate for the trai ler, you wi ll need a larger than normal
t urning radius .
When passing, remember that you cannot accelerate as fast as you nor mally wou ld because of t he added load . Make sure yo u have
enough room to pass. After passing, al low plenty of room for your
trai ler before changing lanes again .
Avo id jerky starts, sharp turns or rapid lane changes.

Engine oil consumption
The engine in your vehicle depends on an adequate
amount of oil to lubricate and cool all of its moving parts.
In order to prov ide effect ive lubrication and cool ing of in ternal
engine components, all internal combustion engines consume a
certain amount of o il. Oil consumption varies from engine to engine
and may change significantly over the life of the engine . Typically,
eng ines wi th a specified break -in period
(see ~ page 243) consume
more oil during the break -in period than they consume after oi l
consumption has stabi lized .
Under norma l condit ions, the rate of o il consumption depends on
the quality and viscosity of the oil, the RPM (revo lutions per minute)
at whic h the engine is operated, t he amb ient te mperature and road
conditions. Further factors are the amount of oil dilution from water
condensatio n or fuel residue and t he oxidation level of the o il. As
any engine is subject to wear as mileage builds up, the oil consump ­
t ion may increase over time until rep laceme nt of worn components
may become necessary .
With all these variables coming into play, no standard rate of oil consu mption can be estab lished or specified. T here is no a lternative
to regu lar and frequent checking of the oil level, see
Note .
If the yellow eng ine o il level warni ng symbol in the instrument
cluster ~ lights up, you should check the oil level as soon as
possible
with the oil dipstick ~ page 277 . Top off the o il at your
earl iest
convenience~ page 278.
& WARNING
Bef ore you che ck anything in the eng ine comp artment , alway s
read and heed all WARNINGS
~ & in "Working in the engine
c ompartment " on
page 27 3.
0 Note
Driving with an insuff ic ient oil level is l ikely to cause severe damage
to the engine.
[ i ] Tip s
• The oil pres sure warning displ ay "e:7: is n ot an indi cator of the oil
level . Do not rel y on it. Instead, check the oil level in your engine at
regular inter vals, preferably ea ch time you refuel , and al way s before
going on a long trip.
• If you have the impression your engine consumes excessive
amounts of oi l, we reco mmend that you consult your Audi dealer to
have the cause of your concern properly diagnosed . Keep in mind
that t he accurate measurement of oil consumptio n requ ires great
care and may take some time. Your Audi dealer has instructions
about how t o measure oil cons umpt ion accurately. •

Repl ac ing a fu se
A problem in the electrical system may be caused by a
blown fuse.

instrument panel :
removing cover plate
to access fuses
Fig . 233 Fuse carrier
behind the instrument
panel end face, cover
removed
- Switch off the ignition and the electrical component
affected.
- Carefully pry the face cover off the instrument panel
using the ignition key or a
screwdriver ~ fig. 232.
- Check the fuse listing on the next pages to find out which
fuse belongs to the component which has failed
~ page 327, "Fuse list".
- Remove the blown fuse with the plastic clip provided.
The clip is located on the holder in the fuse box.
- Replace a blown fuse (recognizable by the melted metal
strip inside) with a fuse of the same amperage .
- Firmly snap the cover back onto the instrument panel
face.
The various electrical circuits are protected by fuses. The fuses are
clustered in a centralized unit. The unit is located behind the face
panel at the end of the instrument panel. The crank for operating
the sunroof in case of a power failure is also stored behind the face
panel ~ page 70.
Two spare fuses and a sticker identifying the fuses are located on
the inside of the fuse box cover.
You are well advised to keep a supply of spare fuses in your vehicle.
Fuses with the proper ampere ratings are available at your Audi
d ea le r.
& WARNING
Never replace a fuse with one that has a higher amperage rating.
• A fuse with a too high amperage could damage the electrical
part and cause a fire.
