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.

If you are in an area of extreme cold,
where the temperature falls below –22°F
(–30°C), it is recommended that you use
either an SAE 5W-30 synthetic oil or an
SAE 0W-30 oil. Both will provide easier
cold starting and better protection for your
engine at extremely low temperatures.
Engine Oil Additives
Don’t add anything to your oil. The recom-
mended oils with the starburst symbol are
all you will need for good performance and
engine protection.
When to Change Engine Oil
If any one of these is true for you, use the
short trip/city maintenance schedule:
 Most trips are less than 5 miles (8 km).
This is particularly important when out-
side temperatures are below freezing.
 Most trips include extensive idling (such
as frequent driving in stop-and-go traf-
fic).
 The vehicle is used for delivery service,
police, taxi or other commercial applica-
tion.Driving under these conditions causes
engine oil to break down sooner. If any one
of these is true for your vehicle, then you
need to change your oil and filter every
3,750 miles (6,000 km) or 3 months –
whichever occurs first.
If none of them is true, use the long trip/
highway maintenance schedule. Change
the oil and filter every 7,500 miles (12,000
km) or 6 months – whichever occurs first.
Driving a vehicle with a fully warmed
engine under highway conditions will
cause engine oil to break down slower.
What to Do with Used Oil
Used engine oil contains certain elements
that may be unhealthy for your skin and
could even cause cancer. Don’t let used oil
stay on your skin for very long. Clean your
skin and nails with soap and water, or a
good hand cleaner. Wash or properly dis-
pose of clothing or rags containing used
engine oil. See the manufacturer’s warn-
ings about the use and disposal of oil prod-
ucts.
Used oil can be a threat to the environ-
ment. If you change your own oil, be sure
to drain all the oil from the filter before dis-
posal. Never dispose of oil by putting it in
the trash, pouring it on the ground, into
sewers, or into streams or bodies of water.
Instead, recycle it by taking it to a place
that collects used oil. If you have a problem
properly disposing of your used oil, askyour SUZUKI dealer, a service station or a
local recycling center for help.
Engine Air Cleaner/FilterThe engine air cleaner/filter is located on
the passenger’s side of the engine com-
partment. See “Engine Compartment
Overview” in this section for more informa-
tion on location.
When to Inspect the Engine Air Cleaner/
Filter
Inspect the air cleaner/filter every 7,500
miles (12,000 km) or 6 months – whichever
occurs first.
Replace every 30,000 miles (48,000 km)
or 24 months – whichever comes first.
If you are driving in dusty/dirty conditions,
inspect the filter every 3,750 miles (6,000
CAUTION
Use only engine oil with the Ameri-
can Petroleum Institute Certified For
Gasoline Engines starburst symbol.
Failure to use the recommended oil
can result in engine damage not cov-
ered by your warranty.

km) or 3 months. If necessary, clean or
replace it.
How to Inspect the Engine Air Cleaner/
Filter
To inspect the air cleaner/filter, remove the
filter from the vehicle and lightly shake the
filter to release loose dust and dirt. If the fil-
ter remains “caked” with dirt, a new filter is
required.
To inspect or replace the filter, do the fol-
lowing:
1) Remove the four screws on the cover.
2) Lift off the cover.
3) Check or replace the engine air
cleaner/filter. See “Normal Mainte-
nance Replacement Parts” in this sec-
tion for replacement part numbers.
4) Reinstall the filter, put the cover back on
tightly, and tighten the screws.
Automatic Transmission FluidTo ensure proper functioning, efficiency,
and durability of the automatic transmis-
sion, be sure to keep the transmission fluid
at the proper level. Too much or too little
fluid can cause problems.
The fluid level must be checked with the
engine running and the selector lever in P
(Park). The vehicle must be up to normal
operating temperature and parked on level
ground.
The normal operating temperature for the
fluid will be reached after driving about 10
minutes.
Checking Automatic Transmission Fluid
Level
If the fluid is contaminated or discolored,
change the automatic transmission fluid.
A decrease in the fluid level indicates a
leak in the automatic transmission. If
noted, contact your SUZUKI dealer for
repair as soon as possible.1) Start the engine.
2) Warm up the engine until the tempera-
ture of the automatic transmission fluid
reaches approximately 40°C (104°F).
3) Move the selector lever from “P” to “1”
and return to “P”. Wait for a few sec-
onds at each select position until the
selected gears are fully engaged.
WARNING
Operating the engine with the air
cleaner/filter off can cause you or
others to be burned. The air cleaner
not only cleans the air, it helps to
stop flame if the engine backfires. If it
isn’t there and the engine backfires,
you could be burned. Don’t drive with
it off, and be careful working on the
engine with the air cleaner/filter off.
CAUTION
If the air cleaner/filter is off, a backfire
can cause a damaging engine fire.
And, dirt can easily get into your
engine, which will damage it. Always
have the air cleaner/filter in place
when you’re driving.

Hydraulic ClutchThere is one reservoir for both the brake
and the hydraulic clutch fluid. See “Brakes”
in this section for more information.
The hydraulic clutch linkage in your vehicle
is self-adjusting. The master cylinder res-
ervoir is filled with hydraulic fluid.
A fluid loss in this system could indicate a
problem. Have the system inspected and
repaired.
When to Check and What to Use
Refer to the Maintenance Schedule to
determine how often you should check the
fluid level and for the proper fluid. See sec-
tion 6.
How to Check and Add Fluid
To check the fluid level, look on the side of
the reservoir. If the fluid level is betweenthe MIN and the MAX marks on the reser-
voir, the fluid level is correct. The reservoir
is located near the back of the engine com-
partment on the driver’s side of the vehicle.
See “Engine Compartment Overview” in
this section for more information on loca-
tion.
Engine CoolantThe following explains your cooling system
and how to add coolant when it is low. If
you have a problem with engine overheat-
ing, see “Engine Overheating” in this sec-
tion.
What to Use
The cooling system in your vehicle is
designed to use either Dex-cool coolant,
which is red in color, or silicate based cool-
ant, which is blue. These two types of cool-
ant are not compatible with each other and
should never be mixed. Therefore, if the
original coolant in your vehicle’s cooling
system was red, then you should use only
Dex-cool coolant for the life of your vehicle.
If the original coolant in your vehicle's cool-
ing system was blue, then you should use
only silicate based coolant for the life of
your vehicle. Even if the cooling system
has been completely drained before a refill,
do not switch types of coolant.Use a 60/40 mixture of clean, drinkable
water and engine coolant which won’t
damage aluminum parts. If another type of
coolant is used, aluminum parts might be
subject to corrosion.
You can also use a recycled coolant with a
complete coolant flush and refill. If you use
this coolant mixture, you don’t need to add
anything else.
A 60/40 mixture of clean, drinkable water
and proper coolant will:
 Give freezing protection down to –33°F
(–36°C).
 Give boiling protection up to 268°F
(131°C).
 Protect against rust and corrosion.
 Help keep the proper engine tempera-
ture.
 Let the warning lights and gauges work
as they should.
For protection in extremely cold weather
conditions, use a 50/50 mixture of clean,
drinkable water and proper coolant.
WARNING
Do not mix Dex-cool and silicate
based coolant in your coolant sys-
tem.
The mixture can damage the cooling
system.

If you have to add coolant more than four
times a year, have your SUZUKI dealer
check your cooling system.Checking Coolant
The engine coolant surge tank is located
on the driver’s side of the engine compart-
ment. See “Engine Compartment Over-
view” in this section for more information
on location.The vehicle must be on a level surface.
When your engine is cold, the coolant level
should be between MAX and MIN mark on
the coolant surge tank. The level rises at
engine operation temperature and drops
again when the engine cools down.
Adding Coolant
If the level falls below the MIN mark, add
the proper coolant mixture at the surge
tank, but only when the engine is cool. If
the surge tank is empty, a special fill proce-
dure is necessary. See “Cooling System”
in this section for instructions on “How to
Add Coolant to the Coolant Surge Tank”.
WARNING
Adding only plain water to your cool-
ing system can be dangerous. Plain
water, or some other liquid such as
alcohol, can boil before the proper
coolant mixture will. Your vehicle’s
coolant warning system is set for the
proper coolant mixture. With plain
water or the wrong mixture, your
engine could get too hot but you
wouldn’t get the overheat warning.
Your engine could catch fire and you
or others could be burned. Use a 60/
40 mixture of clean, drinkable water
and the proper coolant.
CAUTION
If you use an improper coolant mix-
ture, your engine could overheat and
be badly damaged. The repair cost
wouldn’t be covered by your war-
ranty. Too much water in the mixture
can freeze and crack the engine, radi-
ator, heater core and other parts.
CAUTION
If you use the proper coolant, you
don’t have to add extra inhibitors or
additives which claim to improve the
system. These can be harmful.
WARNING
Never turn the surge tank pressure
cap – even a little – when the engine
and radiator are hot.
Loosening the surge tank pressure
cap when the engine and radiator are
hot can allow steam and scalding liq-
uids to blow out and burn you badly.
WARNING
Don’t spill coolant on a hot engine.
You can be burned if you spill coolant
on hot engine parts. Coolant con-
tains ethylene glycol, and it will burn
if the engine parts are hot enough.
