ServiceYour SUZUKI dealer knows your vehicle
best and wants you to be happy with it. We
hope you’ll go to your SUZUKI dealer for
all your service needs. You’ll get genuine
SUZUKI parts and SUZUKI trained and
supported service people.
We hope you’ll want to keep your SUZUKI
vehicle all SUZUKI. Doing Your Own Service WorkYour vehicle has an air bag system. Before
attempting to do your own service work,
see “Servicing Your Air Bag-Equipped
Vehicle” in section 1.
You should keep a record with all parts
receipts and list the mileage and the date
of any service work you perform. See
“Maintenance Record” in section 6.
Adding Equipment to the Outside of
Yo u r Ve h i c l eThings you might add to the outside of your
vehicle can affect the airflow around it. This
may cause wind noise and affect wind-
shield washer performance. Check with
your SUZUKI dealer before adding equip-
ment to the outside of your vehicle.
FuelUse of the recommended fuel is an impor-
tant part of the proper maintenance of your
vehicle.Gasoline OctaneUse only unleaded gasoline with a posted
octane rating of 87 or higher. In an emer-
gency, you may be able to use a lower
octane rating – as low as 85 – if heavy
knocking does not occur. Refill your tank
with proper fuel as soon as possible. Oth-
erwise, you might damage your engine. If
you are using 87 or higher-octane rating
fuel and you hear heavy knocking, your
engine needs service.California FuelIf your vehicle is certified to meet California
Emission Standards (see the underhood
emission control label), it is designed to
operate on fuels that meet California spec-
ifications. If this fuel is not available in
states adopting California emissions stan-
dards, your vehicle will operate satisfacto-
rily on fuels meeting federal specifications,
but emission control system performance
may be affected. The malfunction indicator
lamp may turn on (see Malfunction Indica-
tor Lamp in section 3) and your vehicle
may fail a smog-check test. If this occurs,
return to your SUZUKI dealer for diagno-
sis.
WARNING
You can be injured and your vehicle
could be damaged if you try to do
service work on a vehicle without
knowing enough about it.
 Be sure you have sufficient knowl-
edge, experience, the proper
replacement parts and tools before
you attempt any vehicle mainte-
nance task.
 Be sure to use the proper nuts,
bolts and other fasteners.
“English” and “metric” fasteners
can be easily confused. If you use
the wrong fasteners, parts can later
break or fall off. You could be hurt.

AdditivesTo provide cleaner air, all gasolines in the
United States are now required to contain
additives that will help prevent engine and
fuel system deposits from forming, allow-
ing your emission control system to work
properly. You should not have to add any-
thing to your fuel. However, some gaso-
lines contain only the minimum amount of
additive required to meet U.S. Environ-
mental Protection Agency regulations.
SUZUKI recommends that you buy gaso-
lines that are advertised to help keep fuel
injectors and intake valves clean. If your
vehicle experiences problems due to dirty
injectors or valves, try a different brand of
gasoline.
Gasoline containing oxygenates, such as
ethers and ethanol, and reformulated gas-
olines may be available in your area to
contribute to clean air. SUZUKI recom-
mends that you use these gasolines.
Some gasolines that are not reformulated
for low emissions may contain an octane-
enhancing additive called methylcyclopen-tadienyl manganese tricarbonyl (MMT);
ask the attendant where you buy gasoline
whether the fuel contains MMT. SUZUKI
does not recommend the use of such gas-
olines. Fuels containing MMT can reduce
the life of spark plugs and the performance
of the emission control system may be
affected. The malfunction indicator lamp
may turn on. If this occurs, return to your
SUZUKI dealer for service.
Fuels in Foreign CountriesIf you plan on driving in another country
outside the United States or Canada, the
proper fuel may be hard to find. Never use
leaded gasoline or any other fuel not rec-
ommended in the previous text on fuel.
Costly repairs caused by use of improper
fuel wouldn’t be covered by your warranty.
To check the fuel availability, ask an auto
club, or contact a major oil company that
does business in the country where you’ll
be driving.
Filling Your Tank
CAUTION
Your vehicle was not designed for
fuel that contains methanol. Don’t
use fuel containing methanol. It can
corrode metal parts in your fuel sys-
tem and also damage the plastic and
rubber parts. That damage wouldn’t
be covered under your warranty.
WARNING
Fuel vapor burns violently and a fuel
fire can cause severe injuries. To help
avoid injuries to you and others, read
and follow all the instructions on the
pump island. Turn off your engine
when you are refueling. Don’t smoke
if you’re near fuel or are refueling
your vehicle. Keep sparks, flames
and smoking materials away from
fuel. Don’t leave the fuel pump unat-
tended when refueling your vehicle –
this is against the law in some
places. Keep children away from the
fuel pump; never let children pump
fuel.

To open the fuel filler door, pull up on the
fuel filler door release lever located on the
floor to the left of the driver’s seat.
The fuel cap is located on the passenger’s
side of your vehicle.While refueling, hang the tethered cap
inside the fuel door.
To remove the fuel cap, turn it slowly to the
left (counterclockwise).
Be careful not to spill fuel. Don’t top off or
overfill your tank, and wait a few seconds
after you’ve finished pumping before you
remove the nozzle. Clean fuel from painted
surfaces as soon as possible. See “Clean-
ing the Outside of Your Vehicle” in this sec-
tion.
When you put the fuel cap back on, turn it
to the right (clockwise) until you hear a
clicking sound. Make sure you fully install
the cap. The diagnostic system can deter-
mine if the fuel cap has been left off or is
improperly installed. This would allow fuel
to evaporate into the atmosphere. See
“Malfunction Indicator Lamp” in section 3.
N4U5041A
WARNING
If you spill fuel and then something
ignites it, you could be badly burned.
Fuel can spray out on you if you open
the fuel cap too quickly. This spray
can happen if your tank is nearly full,
and is more likely in hot weather.
Open the fuel cap slowly and wait for
any “hiss” noise to stop. Then
unscrew the cap all the way.
WARNING
If a fire starts while you’re refueling,
don’t remove the nozzle. Shut off the
flow of fuel by shutting off the pump
or by notifying the station attendant.
Leave the area immediately.
CAUTION
If you need a new fuel cap, be sure to
get a genuine SUZUKI cap or its
equivalent. Your SUZUKI dealer can
get one for you. If you get the
improper type, it may not fit properly.
This may cause your malfunction
indicator lamp to light and may dam-
age your fuel tank and emissions
system. See “Malfunction Indicator
Lamp” in the Index.

Hood
Hood ReleaseTo open the hood, do the following.
1) Pull the hood release handle located at
the lower left side of the instrument
panel.
WARNING
Never fill a portable fuel container
while it is in your vehicle. Static elec-
tricity discharge from the container
can ignite the gasoline vapor. You
can be badly burned and your vehicle
can be damaged if this occurs. To
help avoid injury to you and others:
 Dispense gasoline only into
approved containers.
 Do not fill a container while it is
inside a vehicle, in a vehicle’s
trunk, pickup bed or on any surface
other than the ground.
 Bring the fill nozzle in contact with
the inside of the fill opening before
operating the nozzle. Contact
should be maintained until the fill-
ing is complete.
 Don’t smoke while pumping gaso-
line.
WARNING
An electric fan under the hood can
start up and injure you even when the
engine is not running. Keep hands,
clothing and tools away from any
under hood electric fan.
WARNING
Things that burn can get on hot
engine parts and start a fire. These
include liquids like fuel, oil, coolant,
brake fluid, windshield washer and
other fluids, and plastic or rubber.
You or others could be burned. Be
careful not to drop or spill things that
will burn onto a hot engine.

Engine OilIf the oil pressure light appears on the
instrument cluster, it means you need to
check your engine oil level right away.
For more information, see “Oil Pressure
Light” in section 3.
You should check your engine oil level reg-
ularly; this is an added reminder.
Checking Engine Oil
It’s a good idea to check your engine oil
every time you get fuel. In order to get an
accurate reading, the oil must be warm
and the vehicle must be on level ground.Use the engine oil dipstick to check the oil
level. The dipstick’s handle will be a yellow
ring. See “Engine Compartment Overview”
in this section for the location of the engine
oil dipstick.
Turn off the engine and give the oil several
minutes to drain back into the oil pan. If
you don’t, the oil dipstick might not show
the actual level.
Pull out the dipstick and clean it with a
paper towel or cloth, then push it back in all
the way. Remove it again, keeping the tip
down and check the level.
When to Add Engine OilIf the oil is at or below the MIN mark, then
you’ll need to add at least one quart of oil.
But you must use the right kind. This sec-
tion explains what kind of oil to use. For
engine oil crankcase capacity, see “Capac-
ities and Specifications” in this section.
CAUTION
Don’t add too much oil. If your engine
has so much oil that the oil level gets
above the upper mark that shows the
proper operating range, your engine
could be damaged.

This (A) is where you add oil. See “Engine
Compartment Overview” on a previous
page in this section for more information
on location.
Be sure to add enough oil to put the level
somewhere in the proper operating range.
Push the dipstick all the way back in when
you’re through.What Kind of Engine Oil to Use
Oils recommended for your vehicle can be
identified by looking for the starburst sym-
bol.
This symbol indicates that the oil has been
certified by the American Petroleum Insti-
tute (API). Do not use any oil which does
not carry this starburst symbol.
If you choose to perform the engine oil
change service yourself, be sure the oil
you use has the starburst symbol on the
front of the oil container. If you have your
oil changed for you, be sure the oil put into
your engine is American Petroleum Insti-
tute certified for gasoline engines.
You should also use the proper viscosity oil
for your vehicle, as shown in the viscosity
chart. SAE 5W-30
As shown in the viscosity chart, SAE
5W-30 is the only viscosity grade recom-
mended for your vehicle. However, if it’s
going to be –4°F (–20°C) or above and
SAE 5W-30 is not available, you may use
SAE 10W-30.
These numbers on an oil container show
its viscosity, or thickness. Do not use
other viscosity oil such as SAE 10W-40
or SAE 20W-50 under any conditions.
