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.

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.

If the warning continues and you have not
stopped, pull over, stop, and park your
vehicle right away.
If there’s still no sign of steam, you can idle
the engine for three minutes while you’re
parked. If you still have the warning, turn
off the engine and get everyone out of the
vehicle until it cools down.
You may decide not to lift the hood, but to
get service help right away.Cooling SystemThe engine coolant surge tank is located in
the rear of the engine compartment on the
driver’s side.If the coolant inside the coolant surge tank
is boiling, don’t do anything else until it
cools down. The vehicle should be parked
on a level surface. Make sure that the air
conditioning is turned off.
The coolant level should be between the
MIN and MAX marks on the coolant surge
tank when the engine is cool. If it isn’t, you
may have a leak at the pressure cap or in
the radiator hoses, heater hoses, radiator,
water pump or somewhere else in the cool-
ing system.If there seems to be no leak, with the
engine on, check to see if the electric
engine cooling fan is running. If the engine
is overheating, the fan should be running.
If it isn’t, your vehicle needs service.
How to Add Coolant to the Coolant
Surge Tank
If you haven’t found a problem yet, check
to see if coolant is visible in the surge tank.
If coolant is visible but the coolant level
isn’t between the MIN and MAX marks,
add a 60/40 mixture of clean, drinkable
water and proper coolant at the coolant
surge tank, but be sure the cooling system,
including the coolant surge tank pressure
cap, is cool before you do it. See “Engine
Coolant” in this section for more informa-
tion.
If no coolant is visible in the surge tank,
add coolant as follows:
WARNING
An electric engine cooling fan under
the hood can start up even when the
engine is not running and can injure
you. Keep hands, clothing and tools
away from any underhood electric
fan.
WARNING
Heater and radiator hoses, and other
engine parts, can be very hot. Don’t
touch them. If you do, you can be
burned.
Don’t run the engine if there is a leak.
If you run the engine, it could lose all
of the coolant. That could cause an
engine fire, and you could be burned.
Get any leak fixed before you drive
the vehicle.
CAUTION
Engine damage from running your
engine without coolant isn’t covered
by your warranty.
CAUTION
This vehicle has a specific coolant fill
procedure. Failure to follow this pro-
cedure could cause your engine to
overheat and be severely damaged.

1) Park the vehicle on a level surface. You
can remove the coolant surge tank
pressure cap when the cooling system,
including the coolant surge tank pres-
sure cap and upper radiator hose, is no
longer hot. Turn the pressure cap
slowly counterclockwise (left) about two
or two and one-half turns. If you hear a
hiss, wait for that to stop. This will allow
any pressure still left to be vented out
the discharge hose.
WARNING
Never turn the cap when the cooling
system, including the coolant surge
tank pressure cap, is hot.
Steam and scalding liquids from a
hot cooling system can blow out and
burn you badly. They are under pres-
sure, and if you loosen the coolant
surge tank pressure cap – even a lit-
tle – they can come out at high
speed. Wait for the cooling system
and coolant surge tank pressure cap
to cool if you ever have to loosen the
pressure cap.
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 a proper coolant.

CAUTION
In cold weather, water can freeze and
crack the engine, radiator, heater
core and other parts. Use the recom-
mended coolant and the proper cool-
ant mixture.
WARNING
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.
Don’t spill coolant on a hot engine.

When your brake fluid falls to a low level,
your brake warning light will come on. See
“Brake System Warning Light” in section 3.
What to Add
When you do need brake fluid, use only
DOT-3 brake fluid. Use new brake fluid
from a sealed container only. See “Recom-
mended Fluids and Lubricants” in section
6.
Always clean the brake fluid reservoir cap
and the area around the cap before remov-
ing it. This will help keep dirt from entering
the reservoir.Brake Wear
Your vehicle has front and rear disc brakes.
Disc brake pads have built-in wear indica-
tors that make a high-pitched warning
sound when the brake pads are worn and
new pads are needed. The sound may
come and go or be heard all the time your
vehicle is moving (except when you are
pushing on the brake pedal firmly).Some driving conditions or climates may
cause a brake squeal when the brakes are
first applied or lightly applied. This does
not mean something is wrong with your
brakes.
Properly torqued wheel nuts are necessary
to help prevent brake pulsation. When tires
are rotated, inspect brake pads for wear
and evenly tighten wheel nuts in the proper
sequence to SUZUKI torque specifica-
tions.
Brake linings should always be replaced as
complete axle sets.
See “Brake System Inspection” in section
6.
WARNING
If you have too much brake fluid, it
can spill on the engine. The fluid will
burn if the engine is hot enough. You
or others could be burned, and your
vehicle could be damaged.
WARNING
With the wrong kind of fluid in your
brake system, your brakes may not
work well, or they may not even work
at all. This could cause a crash.
Always use the proper brake fluid.
CAUTION
 Using the wrong fluid can badly
damage brake system parts. For
example, just a few drops of min-
eral-based oil, such as engine oil,
in your brake system can damage
brake system parts so badly that
they’ll have to be replaced. Don’t let
someone put in the wrong kind of
fluid.
 If you spill brake fluid on your vehi-
cle’s painted surfaces, the paint fin-
ish can be damaged. Be careful not
to spill brake fluid on your vehicle.
If you do, wash it off immediately.
See “Appearance Care” in the
Index.
WARNING
The brake wear warning sound
means that soon your brakes won’t
work well. That could lead to an acci-
dent. When you hear the brake wear
warning sound, have your vehicle
serviced.
CAUTION
Continuing to drive with worn-out
brake pads could result in costly
brake repair.
