brake AUDI A3 2012 Owner´s Manual

108 Driving Safely
- never lean out the window
- never put your feet out the window
- never put your feet on the instrument panel
- never rest your feet on the seat cushion or
back of the seat
- never ride in the footwell
- never ride in the cargo area
A WARNING
Improper seating positions increase the
risk of serious personal injury and death
whenever a vehicle is being used .
-
- Always make sure that all vehicle occu­
pants stay in a proper seating position
and are properly restrained whenever the
vehicle is being used.
Pedal area
Pedals
The pedals must always be free to move and
must never be interfered with by a floor mot
or any other object.
Make sure that all pedals move freely without
interference and that nothing prevents them
from returning to their original positions.
Only use floor mats that leave the pedal area
free and can be secured with floor mat fasten­
ers.
If a brake circuit fails, increased brake pedal
travel is required to bring the vehicle to a full
stop.
A WARNING
Pedals that cannot move freely can cause
loss of vehicle control and increase the risk
of serious injury.
- Never place any objects in the driver's
footwell. An object could get into the
pedal area and interfere with pedal func­
tion. In case of sudden braking or an ac­
cident, you would not be able to brake or
accelerate!
- Always make sure that nothing can fall
or move into the driver's footwell.
Floor mats on the driver side
Always use floor mots that con be securely
attached to the floor mot fasteners and do
not interfere with the free movement of the
pedals.
.,. Make sure that the floor mats are properly
secured and cannot move and interfere with
the pedals ~.&_ .
Use only floor mats that leave the pedal area
unobstructed and that are firmly secured so
that they cannot slip out of position . You can
obtain suitable floor mats from your author­
ized Audi Dealer.
Floor mat fasteners are installed in your Audi .
Floor mats used in your vehicle must be at­
tached to these fasteners. Properly securing
the floor mats will prevent them from sliding into positions that could interfere with the
pedals or impair safe operation of your vehicle
in other ways.
_&. WARNING
Pedals that cannot move freely can result
in a loss of vehicle control and increase the
risk of serious personal injury.
- Always make sure that floor mats are
properly secured.
- Never place or install floor mats or other
floor coverings in the vehicle that cannot
be properly secured in place to prevent
them from slipping and interfering with
the pedals or the ability to control the
vehicle.
- Never place or install floor mats or other
floor coverings on top of already instal­
led floor mats. Additional floor mats and
other coverings will reduce the size of
the pedal area and interfere with the pedals .
- Always properly reinstall and secure floor
mats that have been taken out for clean­
ing.
- Always make sure that objects cannot fall into the driver footwell while the ve-
hicle is moving. Objects can become
~

trapped under the brake pedal and accel­
erator pedal causing a loss of vehicle
control.
Stowing luggage
Loading the luggage compartment
All luggage and other objects must be prop­
erly stowed and secured in the luggage com­
partment.
F ig . 119 Safe load position ing: heavy cargo positioned
as far forward as poss ib le.
Loose items in the luggage compartment can
shift suddenly, changing vehicle handling
characterist ics. Loose items can also increase
the r isk of serio us personal injury in a sudden
vehicle maneuver or in a collision .
.,. Distribute the load evenly in the luggage
compartment .
.,. Always place and properly secure heavy
items in the luggage compartment as far
forward as poss ible
¢ fig . 119.
.,. Secure luggage using the tie-downs provid­
ed

.,. Make sure that the rear seatback is secure ly
latched in place.
A WARNING
Improperly stored luggage or other items
can fly through the vehicle caus ing se rious
personal injury in the event of hard b rak­
ing or an ac cident. To help redu ce the r isk
o f serious persona l injury:
- Always put objects, for examp le, luggage
or other heavy items in the l uggage com­
partment.
Dr ivin g Sa fely 109
-Always secure objects in the luggage
compartment using the t ie-down eyelets
and suitable straps.
A WARNING
Heavy loads w ill influence the way your ve­
hicle handles. To help reduce the risk of a
loss of control leading to serious personal
injury:
-Always keep in mind when transporting
heavy objects, that a change in the cen­
ter of gravity can also cause changes in
veh icle hand ling:
- Always distribute the load as evenly as
possible.
- Place heavy objects as far forward in
the luggage compartment as possible.
- Never exceed the Gross Axle We ight Rat­
ing or the G ross Vehicle Weight Rating
specif ied on the safety compliance stick­
er on the left door jamb. Exceeding per­
miss ible weight standards can cause the
veh icle to slide and handle different ly.
- Please
observe informat ion on safe driv­
ing¢
page 103.
A WARNING
To help prevent poisonous exhaust gas
from being drawn into the vehicle, always
ke ep the rear lid clos ed w hile driving.
- Never transport objects larger than
those fitting completely into the luggage area because the rear lid cannot be fu lly
closed .
- I f you absolutely must dr ive with the rea r
lid open, o bserve the following no tes to
red uce the risk of poison ing:
- Close all windows,
- Close the power roof*,
- Open all air outlets in the instrument
panel,
- Swi tc h off the air rec irculat ion,
- Set the fresh air fan to the highest
speed.

Intelligent technology Notice about data
recorded by vehicle
control modules
Your vehicle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers for the express purpose of capturing
data for retrieval after an accident or crash
event. EDR's are sometimes called "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDR's that were in­
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
Although your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for examp le, engine function, emis­
sion control, as well as for the airbags and
safety belts.
These electronic control modules also record
vehicle-related data during norma l vehicle op­
eration for diagnostic and repair purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a very limited period of
time and stored when a system fault or other
condition is sensed by a control unit. Some of
the data then stored may relate to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only be read and downloaded with special equip­
ment.
Electronic Stabilization
Program (ESP)
Description
ESP helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidding and loss of veh icle control. It works
only when the engine is running. ESP detects
Intelligent technology 161
certain difficult driving situations, including
when the vehicle is beginning to spin (yaw)
out of control and helps you to get the veh icle
back under control by se lectively braking the
wheels, and/or reducing engine power and
providing steering ass istance to help hold the
vehicle on the driver's intended course. The in­
dicator light
G] in the instrument cluster
blinks when ESP is taking action to help you
control the vehicle.
ESP has limitations. It is important to remem­
ber that ESP cannot overcome the laws of
physics.
It will not always be able to help out
under all conditions you may come up against.
For example, ESP may not always be able to
help you master situations where there is a
sudden change in the coefficient of friction of
the road surface. When there is a section of dry road that is suddenly covered with water,
slush or snow, ESP cannot perform the same
way it would on the dry surface . If the vehicle
hydroplanes (rides on a cushion of water in­
stead of the road surface), ESP will not be
able to help you steer the vehicle because con­
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered .
During fast cornering, particularly on winding
roads, ESP cannot always deal as effectively
with difficult driving situations as at lower
speeds. When towing a trailer, ESP is not able
to help you regain control as it would if you
were not tow ing a trailer.
A lways adjust your speed and driving style to
road, traffic; and weather conditions. ESP can­
not override the vehicle's physical limits, in­
crease the available traction, or keep a vehicle
on the road if road departure is a result of
driver inattention. Instead, ESP improves the
poss ibility of keeping the vehicle under con­
trol and on the road dur ing extreme maneu­
vers by using the driver's steering inputs to
help keep the vehicle going in the intended di­
rection. If you are traveling at a speed that
causes you to run off the road before ESP can
provide any assistance, you may not experi­
ence the benefits of ESP .
•
•

162 Intelligent technology
ESP includes and/or works together with the
anti-lock brake system (ABS), brake assist sys­
tem and anti-slip regulation (ASR). ESP is
switched on all the time. In certain situations
when you need less tract ion, you ca n sw itch
off ESP by pressing the button [g] _ Be sure to
switch ESP on again when you no longer need l ess traction .
Anti-lock b raking system (ABS)
ABS prevents the wheels from locking up
when braking. The vehicle can still be steered
even during hard braking. Apply steady pres­
sure to the brake pedal. Do not pump the ped­
al. A puls ing in the b rake pedal ind icates that
the system is he lp ing you to b ra ke the vehicle.
Br ake a ssist system
The brake assist system can decrease braking
d istance. It increases braking power when the
d river presses the brake pedal quick ly in eme r­
gency situations. You must press and hold the
brake peda l until the si tuation is over .
Anti-slip regulation (ASR)
ASR reduces engine power when the drive
wheels begin to spin and adapts the fo rce to
the road co ndit io ns. This makes it easier to
start, ac celerate and drive up hills.
Electronic differential loc k (EDL )
The EDL brakes wheels that are spinn ing and
transfers the drive power to the other drive
wheel or whee ls if the vehicle is equipped with
a ll-wheel d rive*. This funct ion is available up
to abo ut 60 mph (100 km/h).
In extreme cases, EDL automat ically switches
off to help keep the brake on the braked whee l
from ove rheating . EDL w il l switch on aga in au­
tomatically when conditions have returned to
n o rmal.
& WARNING
- ESP, A BS, ASR an d EDL cannot ove rcome
the laws of physics . This is espec ially im ­
portant on slippery or wet roads. If the
systems begin act ing to stab ilize your ve­
hicle, you should immediately cha nge your speed to matc
h the road and t raffic
conditions. Do not let the increased safe­
ty provided by these systems tempt you
to take risks. Do ing so w ill increase the
ris k of a loss of veh icle control , co llision
and serious pe rsonal inj uries .
- Always adapt your speed to road, traffic and weather conditions. The risk of los­
ing control of the vehicle inc reases when
d riving too fast, espec ially through
curves and on slippe ry or wet roads, and
when dr iv ing too close to vehicles up
ahead. ESP, ABS, the brake assist system, EDL an d ASR cannot prevent collisions.
- Always accelera te with special care on
even, smooth s urfaces such as those that
are wet or covered with ice and snow.
The drive wheels can spin even w ith
these assistance systems that cannot al­
ways he lp to red uce the risk of loss of ve­
h icle control.
(D Tips
- ABS and ASR only work correct ly when
all four wheels are equipped with identi­
cal tires. Diffe rent tire sizes can lead to a
reduction in engine powe r.
- You may hear noises when the systems
descr ibed are working .
- If the indicator light
D] or m (USA
mode ls)/ KC] (Canada models) appears,
t here may be a malfunction~

ESP switching on/off
Fig. 151 Ce nter conso le: ESP O FF butto n
The ESP is automat ically activated whe n the
engine is started, and it performs a se lf-test .
II>

As soon as the test is completed, the system
is in normal operating mode.
Switching off
E SP should normally be activated at all times
because this ensures optimum vehicle stabil i­
ty. In certa in situations, it might make sense
to a llow some slip . For example:
- Rocking the vehicle to free it when it is stuck
- Driving in deep snow or on loose ground
- Driving with snow cha ins
Press the
[!I button . The ESP indicator light I)
turns on and S tabil isat ion prog ram off ap­
pears in the d isp lay. ASR deact ivates com­
pletely and the stab ilizat ion effects from the
ESP system are lim ited.
S wi tc hing on
Press the [!I button again. The message S tab i·
li sa tion p rogram on
appears briefly in the dis­
play.
A WARNING
You should only sw itch the ESP off if your
driving ability and the traffic s ituation per­
m it. Please note that when ESP/ASR is de­
act ivated, the drive whee ls can sp in on icy
and slippe ry roads and the vehi cle can
break away - danger of skidding!
(j) Tips
If A udi magnetic ride* is malfunctioning,
the ESP may not switch off or it may
sw itch off automatically.
Braking
General information
What affects braking efficiency?
Operating condit ions and d riving habit s
The brakes on today's automobi les are st ill
subject to wear, depending largely on operat­
ing cond itions and dr iving habits
q .&. . On ve ­
hicles that are either driven mostly in stop­
and -go city traffic or are driven hard, the
brake pads should be checked by your author-
Int ellig ent technolog y 163
ized Audi dea ler more often than specified in
the
W arra nty & M aintenance booklet. Failure
to have your brake pads inspected can result
in reduced brake performance.
On steep slopes, you sho uld use the b raking
effect of the engine. This way, you prevent un­
necessary wear on the brake system. If you
must use your brakes, do not hold the brakes
down cont inuously. Pump the brakes at inter­
vals.
Noises may occur when braking depending on
speed, braking force and outs ide cond it ions
such as temperature and humidity.
Mo isture o r road sal t
If you are driving faster than SO mph (80 km/
h) and the windshield wipers are on, the brake
pads will briefly touch the brake discs in regu­
lar intervals so as to improve react ion time
when brak ing on wet surfaces. You, the driver,
will not not ice anything.
Under certain conditions, for example, when
driv ing through water or very heavy ra in, or
even after washing your veh icle, the braking
effect can be reduced due to moisture (or in
freez ing cond itions ice) on the brake pads. A
few cautious brake applications should dry off
the b ra ke pads or remove any ice coatings.
The effectiveness of the brakes ca n be reduced
when the vehicle is driven on a salt-cove red
road and the brakes are not used. l ikewise,
you clean off accumulated salt coating from brake d iscs and pads w ith a few cautio us ap­
plications o f the b ra ke
¢ .&, .
Corrosion
T here may be a tendency for di rt to b uild up
o n the brake pads and corros ion to fo rm on
the d iscs if the car is not d riven regu larly or
o nly for short tr ips w ith litt le use of the
brakes.
If the brakes a re not used frequently, o r if cor­
ros ion has formed on the discs, it is adv isable
to clean off t he pads and d iscs by braking
firmly a few times from a moderately high
speed ~.&. . .,.

164 Intelligent technolog y
Faults in the bra ke sys tem
If you should notice a sudden increase in
b rake peda l travel, then one of the two brake
circuits may have failed¢.& .
Low brake flu id le vel
Malfunct ions can occur in the brake system if
the brake fluid level is too low . T he brake fluid
l eve l is moni to red electronica lly .
Bra ke lining w ear st atu s
Brake l ining wear may be checked by visual in­
spection of the condition of the brake pads
through the openings in the whee l. If neces­
sa ry, the wheel may be removed for this in ­
spection
¢page 236, Wheel change.
A WARNING
-You should perform braking maneuvers
for the purpose of cleaning the brake
system on ly if road conditions permit.
Other road users must not be put at risk -
you may cause an acc ident!
- Before descending a steep grade, reduce
speed and shift transmiss ion into a lower
gear or lower driving range . Do not ride
the brakes or hold the pedal down too long or too often. This cou ld cause the
brakes to get hot and dimin ish braking
efficiency.
- Do not "r ide the brakes" by resting your
foot on the pedal when yo u do not intend
to bra ke . This may cause the brakes to
overheat, premature wear and increased
stopping distance .
- Under certain climat ic and operating
condit ions such as passing through wa­
ter, driving in heavy rain or after washing
the vehicle, the effectiveness of the brakes can be reduced. In winter, ice can
accumulate on the brake pads, linings,
discs and drums . Carefully apply brakes
for a test . Brakes will dry and ice coat­
ings will be cleaned off after a few care­
ful brake applications.
- Driv ing for an extended period of time on
salt-covered roads w ithout us ing your
brakes can also affect braking efficiency . Clean off accumulated salt coating from
brake discs and pads with a few careful
brake applications.
- If you damage the front spoiler, or if you
install a different spoiler, be sure the a ir
flow to the front brakes is not obstruct­ ed. Otherwise the brake system could
overheat reducing the effectiveness of
the entire brake system.
- Failure of one brake circuit will impa ir
the braking capab ility result ing in an in­
creased stopping distance. Avoid driving
the vehicle and have it towed to the near­
est a utho rized Audi dea le r or q ualified
wo rkshop.
Brake booster '
The brake booster adds extra broking power.
The brake booster works with vacuum pres­
sure which is created only when the eng ine is
run ning ¢.&_ .
_&. WARNING
-Never let the vehicle roll to a stop with
the engine shut off.
- I f the b rake booster is not working, for
examp le when towing yo ur vehicle, or
because the brake booster has somehow
been damaged, the brake pedal must be
pressed conside rably harder to make up
for the lack of booster assistance.
Functioning of Anti-Lock Brake System
(ABS)
ABS prevents the wheels from locking up un­ der broking.
.
The ABS contributes effectively to vehicle con­
trol since it prevents the whee ls from
locking
when the brakes are applied. This means that
the vehicle remains steerable and is less likely
to sk id .
With ABS you do not need to pump th e
brake. Ju st hold the b ra ke pedal down.

However, do not expect that the ABS shortens
braking distance under
all circumstances.
When driving on grave l or on newly fallen
snow on top of icy surfaces, braking distance may be even longer, therefore, under these
circumstances, it is especially important that
you dr ive slowly and with great care .
How th e ABS syste m work s
An automatic check is made when a speed of
about 4 mph (6 km/h) is reached. When this
happens, a pumping noise can be heard .
If an individua l wheel begins to rotate too
slowly in relation to vehicle speed and tends
to lock, the ABS automatically reduces brake
pressure to prevent that wheel from locking.
This automatic adjustment process will cause
a
s light vib ration of the brake pedal and some
noises to alert you that vehicle speed must be
adapted to existing road and traff ic condi­
tions .
A WARNING
Although the ABS is very effective, always
remember that bra king capability is limit­
ed by t ire traction. Always adjust your dr iv­
ing speed according to the road and traffic
conditions . Do not let the extra sa fe ty af ­
forded bytheABStemptyou into taking
extra r isks. The ABS cannot overcome the
laws of physics.
(D Tips
- If ABS is not functioning properly, a
warning light will come on. See
¢ page 18.
- If a fault occurs in the ABS, the EDL is al ­
so not functioning . This is indicated by
the ABS warning light.
Brake assistant
The broke assistant is designed to achieve the
optimum broking effect .
The brake assistan t helps to increase the ef­
fective
b raking power and thus to achieve a
shorter stopping distance . If the driver
Int ellig ent technolog y 165
presses the brake peda l very quick ly, the brake
assistant automatically boosts the braking
force to the max imum level, up to the po int
where the anti-lock brake function (ABS) inter­
venes to stop the whee ls from locking. You
shou ld then keep the brake peda l pressed un ­
t il the vehicle has braked to the required
speed. The brake assistant switches itself off
as soon as you release the b ra ke peda l.
The brake ass istant wi ll not be operative if
there is a ma lfunction in the ABS.
A WARNING
P lease remember that the acc ident risk a l­
ways increases if you drive too fast, espe­
cially in corners or on a slippe ry road, o r if
you follow the vehicle ahead of yo u too
closely . An increased accident risk cannot
be compensated even by the brake assis ­
tant, so always mainta in a safe speed.
Electro-mechanical
power assist
The electro-mechanical power assist helps
the driver when steering .
The degree of power assist is electronically
matched to vehicle speed .
The power steering system assists the driver
so that he can steer the vehicle with reduced physical effort.
Power steering will not work if t he engine is
off . As a result, the steering wheel will be hard
to turn .
A WARNING
If the system deve lops a problem, you
must seek qualified professiona l assis­
tance.
(D Note
If there is an e lectronic malfunction, ser­
votronic
will still function like a conven-
tiona l power steering system, providing a
constant steering support force that is no
-
l onge r proportionate to the vehicle speed. ..,.

1000
miles
(11500 km) and
afterwards
New engine
The engine needs to be run-in during the first
1,000 miles (1 ,500 km) .
For the first 600 mile s (1,000
kilometers ):
.,. Do not use full throttle.
.,. Do not d rive at engine speeds that are more
than 2/3 of the max imimum permitted
RPM .
From 600 to 1,000 miles (1 ,000 to
1,500 kilometers):
.. Speeds can gradually be increased to the
maximum pe rm iss ible road or eng ine speed .
During and after break-in per iod
.,. Do not rev the engine up to h igh speeds
when it is cold. This applies whether the
transmission is i n N (Neutra l) or in gear.
After the break- in peri od
.. Do not exceed maximum engine speed un­
der any circumstances .
.,. Upshift into the next higher gear
before
reaching the red area at the end of the tach­
ometer scale
¢ page 10.
During the first few hours of driving, the en­
g ine's interna l friction is higher than later
when all the moving parts have been broken
i n. How well this break-in p rocess is done de­
pends to a conside rable extent on the way the
ve hicl e is driven d uring the first 1,0 00 miles
(1, 500 k ilome ters).
(D Note
Extremely high engine speeds are auto­
mat ically reduced. However, t hese RPM ­
lim its we re p rogrammed fo r an engi ne
we ll ru n- in, not a new engine .
Driving and environment 169
@) For the sake of the environment
Do not drive with unnecessarily high en­
g ine speeds -upshifting ear ly saves f uel,
reduces noise and protects the environ­
ment.
New tires
If your vehicle is running on new tires, drive
particularly caref ul for the first 300 miles
(500 kilomete rs) afte r fitt ing.
.&, WARNING
N ew tires tend to be sl ippery and mus t al­
so be "b roken -in" . Be sure to remember
this dur ing t he f irst 3 00 m iles (500 kilo­
meters) . Brake gently . Avoid fo llow ing
closely behind other vehicles or other sit­
uations that m ight require sudden, hard
b raking .
New brake pads
Remember that new brake pads do not have a
full brak ing effect dur ing the first 250 m iles
(400 kilomete rs) afte r they a re install ed.
New brake pads have to be "burnished in" be­
fore they have optima l grab¢ .&. .
D uring the brea k-in period, yo u should avo id
putting severe loads on the brakes. Severe
l oads include , for example, sudden hard brak­
i ng, in particular at very h igh speeds or, for
example, on mounta in passes .
.&, WARNING
Until they develop the maximum "bite" for
bes t stopping power, the s urfaces on new
brake p ads re quir e some "breaking -in" dur­
ing the initia l 100 to 150 miles (15 0 to
200 kilometers) of no rma l city driving . You
can compensate for this by pressing the b rake peda l more f irm ly. This applies
whenever new pads are installed.

170 Driving and en vironm ent
Driving through water on roads
Note the following to avoid vehicle damage
when dr iv ing t hrough water, for example on
flooded roads:
- The water must not be any higher than the
bottom of the vehicle body.
- Do not drive faster than walking speed.
A WARNING
After d riving through wate r, mud, slush,
etc., the brakes may be slow to take effect
because o f wet brake ro tors and pads. Dry
the brakes f irst by bra king carefully to re ­
store the full braking effect .
({D Note
Vehicle components such as the engine,
t ransmiss ion, suspens ion or elect rical sys­
tem can be severely damaged by driving
through wate r.
(D Tips
-Che ck the depth of the water before dr iv­
i ng through it.
- Do no t stop the veh icle, dr ive in reverse
or switch the engine off when d riving
th rough water.
- Keep in mind that oncoming vehicles
may c reate waves that raise the wate r
l evel and make it too deep for yo ur vehi­
cle to drive th rough safely .
- Avoid driving thro ugh salt water because
i t can ca use corrosion.
Catalytic converter
-
It is very important that your emission con­
trol system (catalytic converter) is function­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner .
"' Always use lead-free gasoline¢ page 189,
Fuel supply.
"' Never run the tank down a ll the way to
empty .
"' Never put too much motor oil in your en­
gine ¢
page 200, ~ Adding engine oil .
"' Never try to push -or tow-start you r vehicle .
T he ca talytic converter is an efficient "clean­
u p" dev ice bui lt into the exhaust system of
the vehicle . The cata lytic conve rter bu rns
many of the pollutants in the ex ha u st gas be ­
fore they are re leased into the atmosphere.
T he exclusive use of unleaded f uel is c rit ically
important for the life o f the catalyt ic convert ­
er and prope r function ing of the engine .
A WARNING
-Do not park or operate the vehicle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fue l spill or other material wh ich can
cause a fire .
- Do not app ly additional undercoating or
rustp roofing on or near the exhaust
manifold, exhaust pipes, catalytic con­
verter or heat shields. Dur ing driv ing, the
substance used fo r under coating could
overhe at and cause a fire.
((0 Note
-Be aware that just one tank filling with
leaded fuel w ill alr eady ser iously de­
grade the performance of the catalytic
converte r.
- Do not exceed t he cor rect engine oil level
¢page 200.
-Do not dr ive until t he fuel tank becomes
completely empty. The engine cou ld mis­
fire. Unburned fuel could also get in to
the exhaust system and th is co uld cause
t he catalytic converter to overheat .
- Do not tu rn off the igni tion while the ve­
hicle is mov ing.
- Do not continue to ope rate your veh icle
under these conditions, as ot herwise fuel
can reach the catalytic converter. This
cou ld resu lt in overheating of the con­
verter, requir ing its replacement.
- To assu re efficient operation of the Emis -
sion Control System : ..,.

-Have your vehicle maintained properly
and in accordance with the service rec­
ommendations in your Warranty
&
Maintenance booklet.
- Lack of proper maintenance as well as
improper use of the vehicle will impair
the function of the emission control
system and could lead to damage.
@ For the sake of the environment
Even when the Emission Control System is
operating properly, the exhaust gas can
have a sulfur-like exhaust gas smell under
some operating states. This depends on
the sulfur content of the fuel being used .
Using a different brand of fuel may help,
or filling the tank w ith lead-free super
