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.
Malfunction Indicator LampCheck Engine Light
Your vehicle is equipped with a computer
which monitors operation of the fuel, igni-
tion and emission control systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is
intended to assure that emissions are at
acceptable levels for the life of the vehicle,
helping to produce a cleaner environment.
The Check Engine Light comes on to indi-
cate that there is a problem and service is
required. Malfunctions often will be indi-

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.

SERVICE AND APPEARANCE CARE

When replacing the pressure cap, make
sure it is hand-tight.Coolant Surge Tank Pressure Cap
Engine OverheatingYou will find a coolant temperature gauge
on your vehicle’s instrument panel. See
“Engine Coolant Temperature Gauge” in
section 3.If Steam Is Coming From Your Engine
If No Steam Is Coming From Your
Engine
If you get an engine overheat warning, but
see or hear no steam, the problem may not
be too serious. Sometimes the engine can
get a little too hot when you:
 Climb a long hill on a hot day.
 Stop after high-speed driving.
 Idle for long periods in traffic.
If you get the overheat warning with no
sign of steam, try this for a minute or so:
1) In heavy traffic, let the engine idle in
NEUTRAL while stopped. If it is safe to
do so, pull off the road, shift to PARK
(P) or NEUTRAL and let the engine
idle.
2) Turn on your heater to full hot at the
highest fan speed and open the window
as necessary.
If you no longer have the overheat warn-
ing, you can drive. Just to be safe, drive
slower for about 10 minutes. If the warning
doesn’t come back on, you can drive nor-
mally.
CAUTION
Your coolant surge tank cap is a
pressure-type cap and must be
tightly installed to prevent coolant
loss and possible engine damage
from overheating. See “Capacities
and Specifications” for more informa-
tion.
WARNING
Steam from an overheated engine
can burn you badly, even if you just
open the hood. Stay away from the
engine if you see or hear steam com-
ing from it. Just turn it off and get
everyone away from the vehicle until
it cools down. Wait until there is no
sign of steam or coolant before you
open the hood.
If you keep driving when your engine
is overheated, the liquids in it can
catch fire. You or others could be
badly burned. Stop your engine if it
overheats, and get out of the vehicle
until the engine is cool.
CAUTION
If your engine catches fire because
you keep driving with no coolant,
your vehicle can be badly damaged.
The costly repairs would not be cov-
ered by your warranty.
