Breaking in
New engine
The engine needs to be run-in during the first
1,000 miles (1, 500 km).
For the first 600 miles (1 ,000 kilometer s):
"' Do not use full throttle .
"' Do not drive at engine speeds that are more
than
2/3 of the max imum permitted RPM .
From 600 to 1,000 miles (1 ,000 to 1 ,500
kilometers):
"' Speeds can gradually be increased to the maxi­
mum pe rm issib le road or engine speed .
During and after break-in pe riod
"' Do not rev the engine up to high speeds when it
is cold. This applies whether the transmission is
in N (Neutral) or in gear .
After the break-in period
"'Do not exceed maximum engine speed under
any c ircumstances .
"'U pshift into the nex t higher gear
before reach­
ing the red area a t the end of the tachometer
sca le
c=> page 10.
During the first few hours of driving, the eng ine's
internal fric tion is higher than later when all the
mov ing parts have been broken in . How well this
b reak-in process is done depends to a considera­
b le exte nt on the way the veh icle is d rive n during
t he first 1,000 miles (1,500 kilometers).
(D Note
Extremely high eng ine speeds a re au toma ti­
cally reduced . However, these rpm limits are
programme d for a n engine well run-in, not a
new engine.

noise and pro tec ts the envi ronme nt.
Driving and the envir onment
New tires
If your vehicle is runn ing on new tires, d rive very
car efu lly fo r the firs t 35 0 miles (500 kilometers)
a ft er fit ting.
WARNING
New tires tend to be slippe ry and must a lso
be "bro ken-in". Be sure to remembe r th is dur­
i ng the fi rst 350 m iles (500 kilometers).
Brake gent ly. Avoid following closely behind
other vehicles or other s ituations that m ight
r equire sudden, hard b raking .
Avoid damaging the
vehicle
When yo u are dr iv ing o n poor roa ds, or over
cur bs, stee p ramps, e tc., ma ke cert ain that low­
ly ing parts s uch a s spo ile rs a nd exh aust sy stem
parts do no t bottom o ut and get dama ged.
T his is espec ially true for ve hicles with low-s lung
c h ass is (sports c hass is) * and fully loaded
vehicles.
Catalytic converter
It is very important that your emission control
system (catalytic converter) is functioning prop­
erly to ensure that your vehicle is running in an
environmentally sound manner.
"' Always use lead -free gasoline c> page 173,
Fuel supply.
"' Never run the tank down all the way to empty.
"' Never put too much moto r o il in you r engine
c=> page 181, "t':::r. Adding engine oil .
"'Never try to push -or tow -start your veh icle .
The catalytic converter is an efficient "clean-up" device built into the exhaust system of the veh i­
cle. The catalyt ic converter b urns ma ny of the
pollutants in the exhaust gas before they are re­
leased into the atmosphere .
The exclusive use of un leaded fuel is critically im­
portant for the life of the catalytic converter and
prope r fu nct ion ing of the eng ine. ..,.
159

Driving and th e en vironm ent
A WARNING
-The temperature of the exhaust system is
high, both when driving and after stopping
the engine.
- Never touch the exha ust tail pipes once they
have become hot . This could result in burns.
- Do no t park or operate the vehi cle in areas
where the hot exha ust system may come in
contact with dry grass, br ush, fue l spill or
other mater ial which can cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exhaust mani­
fold, exhaust p ipes, catalytic converter or
heat sh ields. During dr iv ing, the substance
used for undercoating could ove rheat and
ca use a fire .
(D Note
-Be aware that just one tank filling with
leaded fuel will a lready ser iously degrade
the performance of the catalytic converter .
- Do not exceed the correct eng ine oi l level
¢ page 181.
-Do not drive until the fuel tank becomes
complete ly empty. The engine cou ld mis­
fire. Unburned fuel could also get into the
exhaust system and this could cause t he
catalytic converte r to overheat.
- Do not turn off the ignition whi le the vehicle
i s mov ing.
- Do not continue to operate your veh icle un­
der these cond itions, as otherwise fue l can
r each the catalytic converte r. This cou ld re­
su lt in ove rheating of t he converte r, req uir ­
i ng its re placement.
- T o assure efficient operation of the Emis­
s ion Control System:
- Have your ve hicle maintained properly and
in accordance with the se rvice recommen ­
dations in your Wa rranty
& Maintenance
book let .
- Lack of proper maintenance as well as im­
proper use of the vehicle will impair the
function of the em ission cont rol system
and co uld lead to damage.

-
® For the sake of the environment
Even when the Emiss ion Control System is op­
e rating properly, the exhaust gas can have a
su lfu r-li ke exhaust gas sme ll under some op­
erating states. T his depends on the sulfur
content of the fuel being used. Us ing a d iffer­
ent brand of fuel may help, or fi lling the tank
with lead-free super g rade gasoline.
Shutting down vehicle
If you would like your vehicle to remain inopera­
tive for a longer pe riod of time, contact an Audi
o r othe r spec ia liz ed dealer. They ca n adv ise you
o n necessa ry p recautions e.g. corros io n preven­
tion, m aintenance and storage . Pay attention to
additional in formation concer ning the battery .

Economical and environ­
mentally-friendly driving
General
Your personal style of driving will determine the
economy of your vehicle, a s well as exhau st and
noise levels .
Fu el economy, env ironmenta l impact, and wear
o n your e ngine, brakes and tires large ly depend
o n t hree fa ctors:
- your personal d riving style
- operat ing cond itions
- technical limitat ions
If you anticipate what you need to do next and
drive economically, you can easily cut your f uel
consumption by 10-lS percent. Th is sect ion wi ll
give you some tips on how you can help the envi­
ronment and your pocketbook .
{l) Tips
The consumption estimates as published by
ENVIRONMENTAL PROTECTIO N AGENCY
(EPA) and T ransport Canada may not corre­
spond to your actual consump tion on the
r oad, which wi ll vary depending upon vehicle
l oad and speed, road a nd wea ther conditions,
tri p l engt h, etc.

Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are acceler­
ating .
11-Avoid unnecessary accelerating and braking.
Vehicles use the most fuel when they are acceler­ ating . If you anticipate what is going to happen
next, you will need to brake less and, thus, accel­
erate less . Let the vehicle coast whenever possi­
ble - for example when you see that the next traf ­
f ic light is red .
Avoid full throttle
Driving a t modera te speeds saves fuel and im­
proves your mileage .
11-Try and keep well be low your car's max imum
speed.
Accelerating gent ly reduces fuel consumption,
engine wear, and does not disturb the environ ­
ment.
F ue l cons umption, exha ust emissions and engine
noise increase disproportionately at high speeds.
If you drive at approximately three quarters of
top speed, fuel consumpt ion will be reduced by
one half. Never drive faster than the posted
speed limit and weather conditions permit.
Reducing unnecessary idling
Even when your car is just idling i t burns up fuel.
11-S hut the engine off w hen you are not driving
the vehicle.
11-Do not warm up the vehicle by letting the en-
gine ru n at idle .
It makes sense to shut off the eng ine in traffic
jams, when wa iting for trains to pass at rai lroad
crossings, or at traffic lights that have long waits
on red . Turn ing the eng ine off for just 30 -40 sec ­
onds saves more fue l than is bu rned starting the
engine agai n.
It takes a long t ime for the engine to warm up
fu lly when it is runni ng at idle . However, wear
and noxious emiss ions are especially high when
the eng ine is wa rm ing up . So you should d rive
Driving and the envir onment
away as soon as you start the eng ine and avoid
running at high rpms w hil e the engine is sti ll
warming up .
(D Note
Do not leave eng ine idling una ttended after
starting. If wa rning lights shou ld come on to
i ndicate improper operation, they would go
unheeded. Extended idling also prod uces
heat, which could result in overheating or
other damage to the vehicle or other proper ­
ty .
Regular maintenance
A badly tuned engine unnecessarily wastes a lot
of fuel .
11-Have your vehicle serviced at regular interva ls.
By having your vehicle regular ly serv iced by an
authorized Audi dea ler helps to ensure that it
runs properly and economically. The cond ition of
your vehicle not only affects its safety and ability
to hold its value, it also affects
fuel con sump­
tion .
Chec k your oil each t ime you fill your tank.
T he amount o f oi l used is related to engine load
and speed.
It is normal fo r the oil consump tion of a new en­
gine to reach its lowest value after a ce rtain m ile­
age has been dr iven.
You m ust dr ive your ve hicle about 3,000 m iles
(5,000 kilometers) befo re yo u can prope rly as­
sess oil consumpt io n.
T h is also app lies to fuel consumption and eng ine
output.
(D Note
- Have your vehicle maintained properly and in accordance with the se rvice recommenda­
tions i n your Warranty
& M aintenance book-
le t. La ck of prope r maintenan ce as we ll as
imp roper use of the ve hicle will im pair the
function of the em ission cont rol sys tem and
co uld lead to damage . .,.
161

Driving and th e en vironm ent
- Do not alter or remove any component of
the Emission Control System unless ap­ proved by the manufacturer.
- Do not alter or remove any device, such as
heat shie lds, switches, ignition wires,
valves, which are designed to protect your
vehicle's Em ission Control System and other
i mportant vehicle components.
Fewer short trips
Fuel consumption will always be relatively high
on shor t trips.
... Try to avoid driving short distances with a cold
engine.
The engine and catalyt ic converter have to reach
their optimal
ope rating temperature to reduce
fue l cons umption and nox ious emissions effec­
tively .
J ust after starting, a co ld eng ine in a m id -s ize ca r
only achieves a f uel economy of 6-8 miles p er
ga llon (30 -40 l/100 km). After about a half a
mile ; fu e l economy cl imbs to 12 mpg (20 l/100
km). After about
2.5 miles (4 km), the engine is
at its prope r operating temperature and fuel
economy has reached a normal level. So you can
see that you sho uld avoid short t rips whenever
possible.
The
outsid e temperature is also critical in this re ­
gard . Your car consumes more fuel in the w in ter
than in the summe r.
Driving offroad
General information
When driving offroad, the f unctions for the elec­
tron ic stabili zation control (ESC) are expanded.
ESC offroad mode can be activated in dr iving sit­
uations in which a whee l lock o r a d ifferent ial
lock fu nction is needed
r=.> page 152.
However, your Audi is not an offroad vehicle.
Never drive the vehicl e in terra in which is not
suitabl e for the vehicle, or which exceeds your
driving skills. Never take any unnecessary ri sks!
162
After driving offroad
- After driving off road, remove branche s and
other deb ris from the rad iator g rille, under ­
body, and w heels . Look especially fo r objects
(stones) that have been caught in the tire
tread.
- Clean the body and the ve hicle unde rbody and
i nspect the ve hicle for possible damages.
- Clean off the dirty windows, headlights, tail
lights and t he license plate.
- Per form a brake test (especia lly after d riving
throug h water) .
A WARNING
-Be especially aware and attentive when d riv ­
ing under diff icu lt cond itions. Damages to
the vehicle and injur ies may occur when
driving at an excess ively high speed o r with
incor rect d riving maneuvers .
- Always ad just yo ur speed and handling to
the roads, terra in, traffic and weathe r con ­
d itions . D rive especially s low if offroad wi th
low visibility.
- Please note that t he wheels can sp in mo re
and the vehicle can swerve when in ESC off­
road mode , espe cially when the road is slip­
pe ry o r has loose surfa ce m aterial.
- Driv ing stability is reduce d in the ESC
Off­
road mode.
@ For the sake of the environment
Avo id harm ing t he env ironmen t and take na­
ture into co nsideration .
(D Tips
Only drive where it is allowed and always stay
on the provided roads and paths .
Driving information
There is only one right way to drive in difficult
conditions: slowly and with caution!
Observe the following when driving on unpaved
r oads :
Ill-

~ Never drive the vehicle in terrain which is not
suitable for the vehicle, or which exceeds your
driv ing skills. Never take any unnecessary risks!
~ Drive slowly and ca utiously!
~ Pay atten tion to the gro und clearance of your
vehicle! The clearance may vary depending on
the load, ground composition and the environ­ ment. The driver is therefore responsib le for
deciding whether a vehicle can handle a specific
s ituation.
~ Activate the E SC off ro ad mode as needed
¢ page 152 .
~ Use the hill de scent a ssis t when driving down
steep slopes
¢ page 153.
Difficult t errain
Never drive in areas that are not familiar to you
and drive slowly when
off road and be prepared
and expect the unexpected (e .g . potholes, bou ld­
ers, tree stumps, etc .)
To prevent the ve hicle from bottoming and avo id
damage to the unde rbody, you should drive
straight across severe bumps in the gro und with
on ly one side of the vehicle so that only two of
you r wheels cross the bumps.
Drive quick ly throug h sandy or marshy off-road
sections and do not stop, if at all possible.
Driving through water on roads
Note the following to avoid vehicle damage whe n
d riving through wa ter, for example on flooded
r oads:
- The wate r must not be any higher tha n the bot­
tom of the vehicle body.
- Do not drive faster than walking speed .
A WARNING
After driving through water o r mud, the brak­
ing effect can be reduced due to mo isture on
t he bra ke discs and b rake pads. A few caref ul
brake applications should dry off t he brakes.
Veh icle components such as the engine,
tra nsmission , suspens ion or electr ical system
can be severe ly damaged by dr iv ing t hrough
water.
Driving and the envir onment
{!) Tips
- Determine the depth before driving through
water.
- Do not stop the vehicle, drive in reverse or
switch the engine off when driving through
water.
- Keep in mind that oncoming vehicles may
create waves that raise the water level and
make it too deep for your vehicle to drive
through safe ly.
- Avoid dr iv ing through salt water (corrosion).

Fig. 143 Permitted ball pos ition of the trailer hitch
Trailer towing weights
With a
factory-installed or an aftermarket trailer
hitch, the maximum permissib le trailer weight is
2,200 lbs (1,000 kg). The maximum permiss ible
unbraked trailer weight is 1,650 lbs (750 kg).
These specifications apply when dr iv ing on roads
h av ing an incl ine of less than 12%.
Permissible tongue load
For best vehicle handling under these changed
conditions, adjust the trailer load so that the
tongue load is at the maximum allowable or
slightly lower. You can get an approximation of
the tongue load w ith a bathroom scale o r you can
measure the load at a trucking company or
weighing station.
With a
factory-installed or an aftermarket trailer
hit ch, the maximum permissib le load on the ball
hitch may not exceed 220 lbs (100 kg).
It is rec­
ommended to use the maximum permissible
l oad.
Trailer load distribution Be sure the load in the trailer is held securely in
place to prevent it from s hiftin g forward, back­
ward or sideways.
Never allow a passenger to ride in a trailer ¢.&.
in Driving instructions on page 166.
Ball mount
The trailer hitch may only be used w ith suitable
ball mount and ball¢
fig. 143. Installation of
the hitch ball must be carr ied out in accordance
with the manufacturer's instructions.
Trailer mode
Engine cooling system
To wing a trailer makes the engine work harder. It
is important that the cooling system's perform ­
ance is up to the additional load . Make sure that
the cooling system has enough fluid .
Tire pressure
When towing a trailer, inflate the tires of your
vehicle to th e cold tire pressure lis ted under "Full
load" on the tire pressure label. The tire pressu re
label is located on the driver's side B-pi llar . In­
flate trailer t ires to trailer and tire manufactur­
ers' specifications.
Lights
T he headlight settings shou ld be checked with
the trai ler attached before driving off. Check to
make s ure both vehicle and trailer lights are
working properly.
Safety chains
Be sure trailer safety chains are properly connect­
ed from the trailer to the hitch on the vehicle.
Leave enough s lack in the chains to permit turn ­
ing corners . When you install safety chains, make
sure they will not drag on the road when you are
driv ing.
The chains should cross under the trai ler tongue
to prevent it from dropping in case of separation
from the hitch.
Driving instructions
Driving with o trailer always requires extra core
and consideration .
To obtain the best possib le handling of vehicle
and trailer, p lease note the following:
.. Do not tow a loaded trailer when your car itself
is not loaded.
.. Be especially care ful when passing other
vehicles .
.. Observe speed limits.
.. Do not drive at the maximum permissib le
speed.
.. Always apply brakes early.
.. Mon itor the temperature gauge .
165

Trailer mod e
Weight d istribution
Towing a loaded trailer with an empty car res ults
in a high ly unstable distribution of weight . If this
cannot be avoided, drive at very low speeds on ly
to avoid the risk of losing steering control.
A "balanced" rig is easie r to operate and con trol.
This means that the tow vehicle should be loaded
to the extent possible and permissible, while
keeping the trai le r as light as possib le under the
circumstances. Whenever possible, transfer
some cargo to the luggage compartment of the
tow vehicle while observ ing tongue load requ ire­
ments and vehicle loading considerat ions.
Spee d
The higher the speed, the more difficult it be­
comes for the driver to contro l the rig. Do not
drive at the maximum permiss ible speed. Reduce
your speed even more if load, weather or w ind
conditions are unfavorable - part icularly when
goi ng downhill.
Reduce veh icle speed
immediatel y if the tra iler
shows the slightest sign of swaying .
Do not try
to stop the sway ing by acc ele rating .
Observe speed lim its. In some areas, speeds for
veh icles towing trailers are lower than for regular
ve hicles.
A lways app ly brakes early. When driving down­
h ill, shift into a lower gear to use the engine
braking effect to slow the veh icle. Use of the
brakes alone can cause them to overheat and fail.
Coolant temp era ture
The coolant temperature gauge¢ page 10 must
be observed carefully. If the needle moves close
to the upper end of the scale, reduce speed im­ mediately and/or turn off the air conditioner.
If the coo lant temperature warning light in the
instr ument cluster starts flashing., pull off
the road, stop and let the engine
idle for about
two minutes to prevent heat bu ild-up.
A WARNING
Anyone not proper ly restrained in a moving
vehicle is at a much greater risk in an acci-
166
-
dent . Never let anyone ride in your car who is
not properly wear ing the restraints provided
by Audi.
Trailer mode notes
Important to know
You r vehicle handles differently when towing a
trailer because o f th e additiona l weight and dif­
ferent weight distribution. Safety, performance
and economy will g reatly depend on how carefu l­
l y you load your trai ler and operate your rig.
Before yo u actually tow your trailer, pract ice
turning, stopping and backing up in an area away
from traffic . Keep practicing unti l you have be­
come complete ly familiar w ith the way your vehi­
cle-tra iler combination behaves and responds.
Backing up is difficult and requires practice .
Backing up with a trailer genera lly requires steer­
ing action opposite to that when backing up your
vehicle without a trailer.
Maintain a greater distance between your vehicle
and the one in fro nt of you . You will need more
room to stop. To compensate for the trailer, you
will need a larger than normal turning radius.
When passing, remember that you cannot accel­ erate as fast as you normally wo uld beca use of
the added load. Make sure you have enough room
to pass. After passing, allow p lenty of room for
your trailer before changing lanes again.
Avoid jerky starts, sharp turns or rapid lane
changes.
@ Tips
- Do not tow a trailer du ring the break-in peri­
od of your vehicle.
- If you tow a trai le r, your Au di may requi re
more frequent maintenance due to the ex­
t ra load ¢
page 232.

Parking on a slope
Do not pork on a slope with a trailer. If it cannot
be avoided, do so only ofter doing the following:
When parking:
.. Apply the foot brake .
.. Have someone place chocks under both the ve­
hicle and the trailer wheels .
.. With chocks in place, slowly release the brakes
until the wheel chocks absorb the load .
.. Turn the wheels towards the curb .
.. Apply the parking brake .
.. Move the selector lever to P.
When restarting after parking:
.. Apply the foot brake .
.. Start the engine .
.. Move the selecto r lever to D/S .
.,. Release the parking brake and slowly pull out
and away from the wheel chocks .
.. Stop and have someone retrieve the wheel
chocks.
(D Tips
If you move the selector lever of the automat­
ic transmission to P before applying the park­
ing brake and before blocking the wheels, you
may have to use more force later to move the
lever out of the P position.

Fuel and Refueling
Gasoline
Fuel supply
Using the right fuel helps keep the environment
clean and prevents engine damage .
Fuel recommendation
The fuel recommended for your vehicle is unlead­
ed premium
grade gasoline. Audi recommends
using TOP TIER Detergent Gasoline with a mini­
mum octane rating of 91 AKI (95 RON). For more
in formation on TOP TIER Detergent Gasoline,
p lease go to the offic ial website
(www.toptiergas.com).
The recommended gasoline octane rating for
your engine can also be found on a label located
on the inside of the fuel filler flap. This rating
may be specified as AKI or RON.
Your vehicle may also be operated using unlead­
ed regular gasoline with a minimum octane rat­
ing of 87 AKI/91 RON. However, using 87 AKI/91
RON octane fuel w ill slightly reduce engine pe r­
formance.
Use unleaded gasoline only. Unleaded gasoline
is available throughout the USA, Canada, and in
most European countries . We recommend that
you do not take your vehicle to areas or countries
where un leaded gasoline may not be available.
For more information on refueling your vehicle,
see
r=;, page 17 4.
Octane rating
Octane rating indicates a gasoline's ability to re­
sist engine damaging "knock" caused by prema­
ture ignit ion and detonation . Therefore, buy ing
the correct grade of gasoline is very important to
help prevent poss ible engine damage and a loss
of eng ine performance.
Gasoline most commonly used in the United
States and Canada has the following octane rat­
ings that can usually be found on the filler pump:
- Premium Grade: 91 - 96 AKI
- Regular Grade: 87 - 90 AKI
Fuel and Refueling
Explanation of the abbreviations :
AKI=
Ant i Knock Index= (R+M)/2 = (RON +MON)/
2
RON = Re search Octane Number
MON= Motor Octane Number.
(D Note
- Do not use any fuel with octane ratings low­
er than 87 AKI or 91 RON otherwise expen­
sive engine damage w ill occur.
- Do
not use leaded gasoline. The use of lead­
ed gasoline will severely damage your vehi­
cle's catalytic converter and its ability to
control exhaust emissions.
Blended gasoline
Use of gasoline containing alcohol or MTBE
(methyl tertiary butyl ether)
You may use unleaded gasoline b lended with al­
cohol or MTBE (commonly referred to as oxygen­
ates) if the blended mixt ure meets the follo wing
criteria:
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
- Anti-knock index must be 87 AKI or higher.
- Blend must contain no more than 3% metha-
nol.
- Blend must contain more than 2% co-solvents.
Blend of gasoline and ethanol (grain alcohol or
ethyl alcohol)
- Anti-knock index must be 87 AKI or higher.
- Blend must not conta in more than 15% etha-
nol.
Blend of gasoline and MTBE
- Anti-knock index must be 87 AKI or higher.
- Blend must contain not more than 15% MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform es­
pecially well for winter or summer dr iving . Dur­
ing seasonal change-ove r, we suggest that you
fill up at busy gas stations where the seasonal
adjustment is more likely to be made in time. ..,.

Fuel and Refueling
CJ) Note
-Methanol fuels which do not meet these re­
quirements may cause corrosion and dam­
age to plastic and rubber components in the
fuel system.
- Do not use fuels that fail to meet the speci­
fied criteria in this chapter.
- If you are unable to determine whether or
not a particular fuel blend meets the speci­
fications, ask your service station or its fuel
supplier .
- Do not use fuel for which the contents can­
not be identified.
- Fuel system damage and performance prob­
lems resulting from the use of fuels differ­
ent from those specified a re not the respon­
s ibilit y of Audi and are not covered under
the New Vehicle or the Emission Control
System Warranties.
- If you experience a loss of fuel economy or
driveability and performance prob lems due
to the use of one of these fuel blends, we
recommend that you switch to unblended
fuel.
Gasoline additives
A major concern among many auto manufactur­
ers is carbon deposit build-up caused by the type
of gasoline you use .
Although gasoline grades differ from one manu­
facturer to another, they have certain things in
common. All gasoline grades contain substances
that can cause deposits to collect on vita l engine
parts, such as fuel injectors and intake valves. Al­
though most gasoline brands include additives to
keep eng ine and fuel systems clean, they are not
equally effective .
Audi recommends using TOP TIER Detergent Gas­
oline . For more information on TOP TIER Deter ­
gent Gasoline, please go to the official website
(www.toptiergas .com) .
After an extended period of using in adequate
fuels, built -up carbon deposits can rob your en­
g ine of peak performance .

(D Note
-Damage or malfunction due to poor fuel
quality is not covered by the Audi New Vehi­
cle Limited Warranty.
- Do not add aftermarket fuel additive prod­
ucts to your fuel tank .
Refueling
Fuel filler neck
The fuel filler neck is located on the right rear
s ide panel behind the fuel filler flap .
If the power locking system should fail , you can
still open the flap manually -for detailed instruc ­
tions see
Q page 176.
You can find the fuel tank capacity of your vehicle in
¢ page 230.
The label on the inside of the fuel fi ller flap tells
you the correct fuel for your vehicle. For more in­
formation about fuel specifications, see
¢ page 173.
Your vehicle fuel tank has an on-board refueling
vapor recovery system. This feature helps to pre­
vent fuel vapors from escaping from the tank and polluting the envi ronment while you refuel your
vehicle . In order to fill the tank properly while
protect ing the env ironment, please follow this
refueling procedure carefully.
A WARNING
Under normal operat ing conditions, never ca r­
ry additional fu el containers in your car. Gas
canisters and other containers used to trans­
port fue l can be dangerous . Such containers,
fu ll or empty, may leak and could cause a fire
in a collision. If you must transport fuel to
use for your lawn mower, snow blower, etc .,
be very careful and always observe local and
state laws regarding the use, transportation
and storage of such fuel containers . Make cer­
tai n the container meets industry standards
(ANSI/ASTM F8S2 -86) .
