SECOND (2):
This position gives you more power than
THIRD (3) but lower fuel economy. You can
use SECOND (2) on hills. It can help con-
trol your speed as you go down steep
mountain roads, but then you would also
want to use your brakes off and on.
FIRST (1):
This position gives you even more power
than SECOND (2) but lower fuel economy.
You can use it on very steep hills, or in
deep snow or mud. If the shift lever is put
in FIRST (1), the transmission won’t shift
into first gear until the vehicle is going
slowly enough.Fuzzy Function
Your automatic transmission will automati-
cally select a adaptive shift pattern using
fuzzy logic.
 Economy mode is applied as often as
possible. Driver adaptive shift patterns are acti-
vated for a minimum time.
 “Load 1” is designed for a driving on
moderate road gradients.
 “Load 2” is active while going up steep
hills.
 “Load 3” is intended for downhill driving
for better engine braking.
Emergency Operation
If the automatic transmission experiences
a malfunction, the malfunction indicator
CAUTION
Don’t drive in SECOND (2) at speeds
over 65 mph (105 km/h), or you can
damage your transmission. Use
THIRD (3) or AUTOMATIC OVER-
DRIVE (D) as much as possible. Don’t
shift into SECOND (2) unless you are
going slower than 65 mph (105 km/h)
or you can damage your engine.
CAUTION
If your front wheels won’t turn, don’t
try to drive. This might happen if you
were stuck in very deep sand or mud
or were up against a solid object. You
could damage your transmission.
Also, if you stop when going uphill,
don’t hold your vehicle there with
only the accelerator pedal. This could
overheat and damage the transmis-
sion. Use your brakes to hold your
vehicle in position on a hill.
CAUTION
The first few shifts may be somewhat
rough on a new vehicle. This is nor-
mal condition and shift feel will
improve soon because the automatic
transmission control system per-
forms adaptation functions.

(2). Then, slowly let up on the clutch pedal
as you press the accelerator pedal.
THIRD (3), FOURTH (4) and FIFTH (5):
Shift into THIRD (3), FOURTH (4) and
FIFTH (5), the same way you do for SEC-
OND (2). Slowly let up on the clutch pedal
as you press the accelerator pedal.
To stop, let up on the accelerator pedal and
press the brake pedal. Just before the
vehicle stops, press the clutch pedal and
brake pedal, and shift to NEUTRAL.
NEUTRAL:
Use this position when you start or idle
your engine.
REVERSE (R):
To back up, press down the clutch pedal,
lift up the ring on the shift lever and shift
into REVERSE (R). Let up on the clutch
pedal slowly while pressing the accelerator
pedal.
Also, use REVERSE (R), along with the
parking brake, for parking your vehicle.Shift Speed
Parking BrakeThe parking brake lever is located between
the bucket seats.
To set the parking brake, hold the brake
pedal down and pull up on the parking
brake lever. If the ignition is on, the brake
system warning light will come on.
To release the parking brake, hold the
brake pedal down. Pull the parking brakelever up until you can press the release
button. Hold the release button in as you
move the brake lever all the way down.
Winter parking tip
Under cold weather conditions, the parking
brake can freeze in the engaged position.
This is most likely to happen if the brakes
are wet.
If there is a risk that the parking brake may
freeze after driving through water deep
enough to wet brake components or after
having the vehicle washed:
1) Apply the parking brake only tempo-
rarily while you put the gear selector
lever in PARK (P) (for automatic tran-
saxle) or in first or reverse gear (for
manual transaxle).
2) Block the rear wheels with wedge
blocks.
3) Release the parking brake.
CAUTION
Shift into REVERSE (R) only after
your vehicle is stopped. Shifting into
REVERSE (R) while your vehicle is
moving could damage your transmis-
sion. The repairs would not be cov-
ered by your warranty.
WARNING
If you skip a gear when you down-
shift, you could lose control of your
vehicle. You could injure yourself or
others. Don’t shift down more than
one gear at a time when you down-
shift.
N4U2016A
CAUTION
Driving with the parking brake on can
cause your rear brakes to overheat.
You may have to replace them, and
you could also damage other parts of
your vehicle. Verify that the parking
brake is fully released and the brake
warning light is off before driving.

Shifting Into Park (P)
(Automatic Transmission)1) Hold the brake pedal down and set the
parking brake.
2) Move the shift lever into PARK (P) posi-
tion.
3) Turn the ignition key to LOCK.
4) Remove the key and take it with you. If
you can leave your vehicle with the igni-
tion key in your hand, your vehicle is in
PARK (P).Leaving Your Vehicle with the Engine
Running
If you have to leave your vehicle with the
engine running, be sure your vehicle is in
PARK (P) and your parking brake is firmly
set before you leave it. After you’ve moved
the shift lever into PARK (P), hold the regu-
lar brake pedal down. Then, see if you can
move the shift lever away from PARK (P)
without first pushing the button. If you can,
it means that the shift lever wasn’t fully
locked into PARK (P).Torque Lock
If you are parking on a hill and you don’t
shift your transmission into PARK (P) prop-
erly, the weight of the vehicle may put too
much force on the parking pawl in the
transmission. You may find it difficult to pull
the shift lever out of PARK (P). This is
called “torque lock.” To prevent torque lock,
set the parking brake and then shift into
PARK (P) properly before you leave the
driver’s seat. To find out how, see “Shifting
Into Park (P)” in this section.
When you are ready to drive, move the
shift lever out of PARK (P) before you
release the parking brake.
If torque lock does occur, you may need to
have another vehicle push yours a little
uphill to take some of the pressure from
the parking pawl in the transmission, so
you can pull the shift lever out of PARK (P).
Shifting Out of Park (P)
(Automatic Transmission)Your vehicle has a brake transmission shift
interlock system which locks the shift lever
in PARK (P) when the ignition is in the
LOCK position. You have to apply your reg-
ular brakes before you can shift from PARK
(P) when the ignition is in the ON position.
See “Automatic Transmission Operation” in
this section.
If you cannot shift out of PARK (P) while
you hold the brake pedal down, try this:
1) Set the parking brake fully.
WARNING
It is dangerous to get out of your
vehicle if the shift lever is not fully in
PARK (P) with the parking brake
firmly set. Your vehicle can roll. Don’t
leave your vehicle when the engine is
running unless you have to. If you
have left the engine running, the
vehicle can move suddenly. You or
others could be injured. To be sure
your vehicle won’t move, even when
you’re on fairly level ground, use the
steps that follow.
WARNING
It can be dangerous to leave your
vehicle with the engine running. Your
vehicle could move suddenly if the
shift lever is not fully in PARK (P)
with the parking brake firmly set.
And, if you leave the vehicle with the
engine running, it could overheat and
even catch fire. You or others could
be injured. Don’t leave your vehicle
with the engine running.

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-

4-15 DRIVING YOUR VEHICLE
85Z03-03E
Run your engine only as long as you must.
This saves fuel. When you run the engine,
make it go a little faster than just idle. That
is, push the accelerator slightly. This uses
less fuel for the heat that you get and it
keeps the battery charged. You will need a
well-charged battery to restart the vehicle,
and possibly for signaling later on with your
headlamps. Let the heater run for a while.
Then, shut the engine off and close the
window almost all the way to preserve the
heat. Start the engine again and repeat
this only when you feel really uncomfort-
able from the cold. But do it as little as pos-
sible. Preserve the fuel as long as you can.
To help keep warm, you can get out of the
vehicle and do some fairly vigorous exer-
cises every half hour or so until help
comes.
If You Are Stuck: In Sand, Mud, Ice or
Snow
In order to free your vehicle when it is
stuck, you will need to spin the wheels, but
you don’t want to spin your wheels too fast.
The method known as “rocking” can help
you get out when you’re stuck, but you
must use caution.For information about using tire chains on
your vehicle, see “Tire Chains” in section 5.Rocking Your Vehicle To Get It Out
First, turn your steering wheel left and
right. That will clear the area around your
front wheels. Then shift back and forth
between REVERSE (R) and a forward
gear (or with a manual transmission,
between FIRST (1) or SECOND (2) and
REVERSE (R)), spinning the wheels as lit-
tle as possible. Release the accelerator
pedal while you shift, and press lightly on
the accelerator pedal when the transmis-
sion is in gear. By slowly spinning your
wheels in the forward and reverse direc-
tions, you will cause a rocking motion that
may free your vehicle. If that doesn’t get
you out after a few tries, you may need to
be towed out. If you do need to be towed
out, see “Towing Your Vehicle” in the fol-
lowing section.
WARNING
If you let your tires spin at high
speed, they can explode, and you or
others could be injured. And, the
transmission or other parts of the
vehicle can overheat. That could
cause an engine compartment fire or
other damage. When you’re stuck,
spin the wheels as little as possible.
Don’t spin the wheels above 35 mph
(55 km/h) as shown on the speedom-
eter.
CAUTION
Spinning your wheels can destroy
parts of your vehicle as well as the
tires. If you spin the wheels too fast
while shifting your transmission back
and forth, you can destroy your trans-
mission. See “Rocking Your Vehicle
To Get It Out.”

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.

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.
