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.
L3U5019A
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.

pulling one way or the other, the alignment
may need to be reset. If you notice your
vehicle vibrating when driving on a smooth
road, your wheels may need to be rebal-
anced.Wheel ReplacementReplace any wheel that is bent, cracked or
badly rusted or corroded. If wheel nuts
keep coming loose, the wheel, wheel bolts
and wheel nuts should be replaced. If the
wheel leaks air, replace it (except some
aluminum wheels, which can sometimes
be repaired). See your SUZUKI dealer if
any of these conditions exist.
Your SUZUKI dealer will know the kind of
wheel you need.
Each new wheel should have the same
load-carrying capacity, diameter, width, off-
set and be mounted the same way as the
one it replaces.
If you need to replace any of your wheels,
wheel bolts or wheel nuts, replace them
only with new SUZUKI original equipment
parts. This way, you will be sure to have
the right wheel, wheel bolts and wheel nuts
for your vehicle.See “Changing a Flat Tire” in this section
for more information.Used Replacement Wheels
Tire Chains
If a Tire Goes FlatIt’s a unusual for a tire to “blowout” while
you’re driving, especially if you maintain
your tire properly. If air goes out of a tire,
WARNING
Using the wrong replacement wheels,
wheel bolts or wheel nuts on your
vehicle can be dangerous. It could
affect the braking and handling of
your vehicle, make your tires lose air
and make you lose control. You could
have a collision in which you or oth-
ers could be injured. Always use the
correct wheel, wheel bolts and wheel
nuts for replacement.
CAUTION
The wrong wheel can also cause
problems with bearing life, brake
cooling, speedometer or odometer
calibration, headlamp aim, bumper
height, vehicle ground clearance and
tire or tire chain clearance to the
body and chassis.
WARNING
Putting a used wheel on your vehicle
is dangerous. You can’t know how it’s
been used or how far it’s been driven.
It could fail suddenly and cause a
crash. If you have to replace a wheel,
use a new SUZUKI original equip-
ment wheel.
CAUTION
Use tire chains only where legal and
only when you must. Use only SAE
class “S” type chains that are the
proper size for your tires. Install them
on the front tires and tighten them as
tightly as possible with the ends
securely fastened. Drive slowly and
follow the chain manufacturer’s
instructions. If you can hear the
chains contacting your vehicle, stop
and retighten them. If the contact
continues, slow down until it stops.
Driving too fast or spinning the
wheels with chains on will damage
your vehicle.
