Daily Inspection ChecklistBefore Driving1) Make sure that windows, mirrors, lights
and reflectors are clean and unob-
structed.
2) Visually check the tires for the following
points:
– the depth of the tread groove
– abnormal wear, cracks and damage
– loose wheel nuts
– existence of foreign material such as
nails, stones, etc.
Refer to “Tires” in the “SERVICE AND
APPEARANCE CARE” section for details.
3) Look for oil or other fluid leaks.
NOTE:
It is normal for water to drip from the air
conditioning system after use.
4) Make sure the hood is fully closed and
latched.
5) Check the headlights, turn signal lights,
brake lights and horn for proper opera-
tion.
6) Lock all doors.
7) Adjust the seat and adjustable head
restraints (if equipped).
8) Check the brake pedal.
9) Adjust the mirrors.
10)Make sure that you and all passengers
have properly fastened your seat belts.
11)Make sure that all warning lights come
on as the key is turned to the “ON” or
“START” position.12)Check all gauges.
13)Make sure that the BRAKE light turns
off when the parking brake is released.
Once a week, or each time you fill your fuel
tank, perform the following under-hood
checks:
1) Engine oil level
2) Coolant level
3) Brake fluid level
4) Power steering (if equipped) fluid level
5) Windshield washer fluid level
6) Hood latch operation
Pull the hood release handle inside the
vehicle. Make sure that you cannot
open the hood all the way without
releasing the secondary latch. Be sure
to close the hood securely after check-
ing for proper latch operation. See the
item “Lubricate Locks, Hinges & Hood
Latch” under “Chassis and Body” in the
“MAINTENANCE SCHEDULE” section
for the lubrication schedule.

VehicleNew Vehicle Break-In
WARNING
Make sure the hood is fully closed
and latched before driving. If it is not,
it can fly up unexpectedly during
driving, obstructing your view and
resulting in an accident.
CAUTION
Your vehicle doesn’t need an elabo-
rate “break-in.” But it will perform
better in the long run if you follow
these guidelines:
 Don’t drive at any one speed – fast
or slow – for the first 500 miles (805
km). Don’t make full-throttle starts.
 Avoid making hard stops for the
first 200 miles (322 km) or so. Dur-
ing this time your new brake linings
aren’t yet broken in. Hard stops
with new linings can mean prema-
ture wear and earlier replacement.
Follow this break-in guideline every
time you get new brake linings.

Speed Sensitive Power Steering
(SSPS) Warning LightIf your vehicle has Speed Sensitive Power
Steering (SSPS), this warning light will
come on briefly when you turn the ignition
to ON as a check to show you the bulb is
working.
Then it should go out after a few seconds.
If the warning light does not come on, have
it fixed so it will be able to warn you if there
is a problem.
If the warning light stays on, or comes on
while you are driving, the SSPS system
may not be working. If this happens, see
your SUZUKI dealer for service.
Hold Mode LightIf your vehicle has this feature, this light will
come on when the Hold mode is active.
If the HOLD mode light flashes, have your
vehicle checked.
See “Hold Mode” under “Automatic Trans-
mission Operation” in section 2 for addi-
tional information on this feature.
Engine Coolant Temperature GaugeYour vehicle is equipped with an engine
coolant temperature gauge. With the igni-
tion in the ON position, this gauge shows
the engine coolant temperature.
If the gauge pointer moves into the red
area, your engine is too hot! It means that
your engine coolant has overheated.
If you have been operating your vehicle
under normal driving conditions, you
should pull off the road, stop your vehicle
and turn off the engine as soon as possi-
ble.
See “Engine Overheating” in section 5.

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.

2) Then keep turning the pressure cap
slowly, and remove it.
3) Fill the coolant surge tank with the
proper mixture to the MAX mark on the
coolant surge tank. Wait about five min-
utes, then check to see if the level is
below the MAX mark. If the level is
below the MAX mark, add additional
coolant to bring the level up to the MAX
mark. Repeat this procedure until the
level remains constant at the MAX mark
for at least five minutes.
4) With the coolant surge tank pressure
cap off, start the engine and let it run
until you can feel the upper radiator
hose getting hot. Watch out for the
engine cooling fan.
By this time, the coolant level inside the
coolant surge tank may be lower. If thelevel is lower than the MAX mark, add
more of the proper mixture to the cool-
ant surge tank until the level reaches
the MAX mark.
5) Then replace the pressure cap. Be sure
the pressure cap is hand-tight and fully
seated. See your SUZUKI dealer, if
necessary.
Power Steering FluidThe power steering fluid reservoir is
located toward the front 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.
When to Check Power Steering Fluid
It is not necessary to regularly check
power steering fluid unless you suspect
there is a leak in the system or you hear an
unusual noise. A fluid loss in this system
could indicate a problem. Have the system
inspected and repaired.How to Check Power Steering Fluid
Turn the key off and then check the fluid
level. The level should be between the MIN
and MAX marks on the reservoir. If the
level is below the MIN mark, add power
steering fluid.
What to Use
To determine what kind of fluid to use, see
“Recommended Fluids and Lubricants” in
section 6. Always use the proper fluid. Fail-
ure to use the proper fluid can cause leaks
and can damage hoses and seals.
