position will automatically stop the
engine before the vehicle is stopped
(approximately 13 km/h or less). At the
same time, the ENG A-STOP indicator
light (green) will remain on.
• The engine is not stopped automati-cally if all of the c onditions to stop the
engine automatically are not met,
even if the brake pedal is pressed
down to decelerate while the ENG A-
STOP indicator light (green) is on.
For details on the conditions for auto-
matically stopping the engine, refer to
“Conditions to stop the engine auto-
matically” in this section.
• To ensure safety when the engine is stopped automatically, the interior
buzzer may sound and the engine
will stall, or the engine may be
restarted.
75RM234
NOTE:
• The engine is not stopped automatically when decelerating without depressing
the brake pedal, for example, by using
engine braking.
• The engine may be stopped automati-
cally when the vehicle is stopped, even if
the engine is not stopped automatically
before stopping the vehicle (approxi-
mately 13 km/h or less).
• Electrical components, such as the navi- gation system or audio system, can be
used while the engine has been stopped
automatically, however, the air condi-
tioner switches to the ventilation posi-
tion.
• For the automatic heating and air condi-
tioning system, airflow is limited (only
under automatic operation) when the
engine is stopped aut omatically, in order
to improve the cooling and heating per-
formance.
3) When you remove your foot from the brake pedal, regardless of whether it is
before or after stopping the vehicle, the
engine is restarted and the ENG A-STOP
indicator light (green) goes off.
• The engine is restarted automatically
if the conditions to restart the engine
automatically are met, even if the
brake pedal is depressed.
For details on the conditions for auto-
matically restarting the engine, refer
to “Conditions to restart the engine
automatically” in this section.

Operating conditions of ENG A-STOP systemStandby conditions
If all of the following conditions are met while driving, the automatic engine stop will be permitted.
• For CVT, the ENG A-STOP indicator light (green) will come on.
#1: If the battery is discharged, for example, if the vehicle has not been used for a long time or electrical components, such as the navi-
gation system or audio system, have not been used for a long ti me while the engine was stopped, it may take some time until th e
system can be in standby.
#2: If any of the warning and indi cator lights affecting the ENG A-STOP system come on, the e ngine will not be stopped automati cally.
#3: The system will be in standby even though the gearshift leve r is in the “N” position, however, the engine will be stopped automati-
cally when the vehicl e is stopped, instead of when it is decelerating (approximately 13 km/ h or less) before stopping.
#4: After the ENG A-STOP indicator light (green) comes on, there may be a signal to prevent stopping the engine. In this case, the ENG
A-STOP indicator light (green) goes off when the vehicle is sto pped, and the engine is not stopped automatically. Also, if any of the
warning and indi cator lights affecting the ENG A-STOP system co me on, the engine will not be stopped automatically.

OPERATING YOUR VEHICLE
75RM4-01E
Eco-Cool (if equipped)When driving while using the air condi-
tioner, cold air is stored in the cooling stor-
age medium of the air conditioner unit.
Since stored cold air will be blown into the
vehicle when the engine has been stopped
automatically by the ENG A-STOP system,
the rise of the inside temperature can be
reduced when the air conditioner is not
running.
For the automatic heating and air condi-
tioning system, reducing the rise of the
inside temperature increases the length of
time that the engine is stopped automati-
cally, leading to improved fuel economy.
NOTE:
Sufficient cold air may not be stored if the
vehicle has not been running for very long
or in a traffic jam. The effect varies
depending on the outside temperature and
the air conditioner settings.
I/S AC Settings (if equipped)• When using the automatic heating andair conditioning system (if equipped),
you can select one of the following set-
tings via the setting mode of the informa-
tion display.
– Standard
– Economy
–Comfort
For details on how to use the information
display, refer to “Information display” in
the “BEFORE DRIVING” section.
• When “Economy” is selected, engine auto stop condition is eased, compared
with “Standard”. Engine auto stop condi-
tion will occur more f requently, the stop
time will be longer, leading to reduction
of fuel consumption.
• When “Comfort” is sel ected, engine auto
stop condition becomes severe, com-
pared with “Standard”. Engine auto stop
condition will occur less frequently, the
stop time will be shorter, leading to more
comfortable cabin condition by air condi-
tioner.
Cruise control (if equipped)The cruise control system allows you to
maintain a steady speed without keeping
your foot on the accelerator pedal. The
controls for operating the cruise control
system are on the steering wheel.
You can use the cruise control system
under the following conditions:
• For manual transaxle vehicle, the gear position is in 3rd, 4th or 5th.
• For CVT vehicle, the select lever is in “D” position, or the gear position is in 3rd,
4th, 5th, 6th or 7th in the manual mode
(if equipped).
• For Auto Gear Shift vehicle, the select lever is in “D” position, or the gear posi-
tion is in 3rd, 4th or 5th in the manual
mode.
• The vehicle speed is about 45 km/h (28
mph) or higher.
WA R N I N G
To help avoid loss of vehicle control,
do not use the cruise control system
when driving in heavy traffic, on slip-
pery or winding roads, or on steep
downhills.

OTHER CONTROLS AND EQUIPMENT
75RM4-01E
Head cooled/Feet warmed heating
Select BI-LEVEL and FRESH AIR, the
temperature selector to the desired tem-
perature position, and the blower speed
selector to the desired blower speed posi-
tion. Unless the temperature selector is in
the fully cold position or fully hot position,
the air that comes out of the center and
side outlets will be cooler than the air that
comes out of the floor outlets.
Normal cooling
Set the air flow selector to VENTILATION,
the temperature selector to the desired tem-
perature position and the blower speed
selector to the desired blower speed posi-
tion, and turn on “A/C” switch. Setting the
blower speed selector to a higher blower
speed position increases cooling efficiency.
You can switch the air intake selector to
either FRESH AIR or RECIRCULATED
AIR as you desire. Choosing RECIRCU-
LATED AIR increases cooling efficiency.
Quick cooling (using recirculated air)
The control settings a re the same as for
normal cooling except you select RECIR-
CULATED AIR and the highest blower
speed. NOTE:
• If you select RECIRCULATED AIR for an
extended period of time, the air in the
vehicle can become contaminated.
Therefore, you should occasionally
select FRESH AIR.
• If your vehicle has been left in the sun with the windows closed, it will cool
faster if you open the windows briefly
while you operate the air conditioner with
the air intake selector at FRESH AIR and
the blower at high speed.
Dehumidifying
Set the air flow selector to a desired air
flow selector position, the temperature
selector to the desired temperature posi-
tion and the blower speed selector to the
desired blower speed position. Also select
FRESH AIR and turn on “A/C” switch.
NOTE:
Because the air conditioner dehumidifies
the air, turning it on will help keep the win-
dows clear, even when blowing heated air
using DEFROST or HEAT & DEFROST
functions.

INSPECTION AND MAINTENANCE
75RM4-01E
Engine coolantSelection of coolantTo maintain optimum performance and
durability of your engine, use SUZUKI gen-
uine coolant or equivalent.
NOTE:
If you use the engine coolant other than
the SUZUKI LLC: Super (Blue) for replace-
ment, follow the schedule of SUZUKI LLC:
Standard (Green). To see the detail of the
maintenance schedule, refer to “Periodic
maintenance schedule” in this section.
This type of coolant is the best for cooling
system for the following reasons:
• The coolant helps maintain properengine temperature.
• It gives proper protection against freez- ing and boiling.
• It gives proper protection against corro- sion and rust. Failure to use the proper coolant can dam-
age your cooling system. Your authorized
SUZUKI dealer can help you select the
proper coolant.
Coolant level checkCheck the coolant le
vel at the reservoir
tank, not at the radiator. With the engine
cool, the coolant level should be between
“FULL” and “LOW” marks.Adding coolant
NOTICE
SUZUKI LLC: Super (Blue) coolant;
This coolant is already diluted to the
proper percentage. Do not dilute with
distilled water additionally. Doing so
may result in the possibility of freez-
ing and/or overheating coolant.
NOTICE
To avoid damaging your cooling sys-
tem:
• Always use a high quality ethylene
glycol base non-silicate type cool-
ant diluted with distilled water at
the correct mixture concentration.
• Check that the proper mix is 50/50
coolant to distill ed water and in no
case higher than 70/30. Concentra-
tions greater than 70/30 coolant to
distilled water will cause overheat-
ing conditions.
• Do not use straight coolant nor plain water (except SUZUKI LLC:
Super (Blue)).
• Do not add extra inhibitors or addi- tives. They may not be compatible
with your cooling system.
• Do not mix different types of base coolants. Doing so may result in
accelerated seal wear and/or the
possibility of severe overheating
and extensive engine or CVT (if
equipped) damage.
WA R N I N G
Swallowing engine coolant can cause
severe injury or death. Inhaling cool-
ant mist or vapors or getting coolant
in your eyes could result in severe
injury.
• Do not drink antifreeze or coolantsolution. If swallowed, do not
induce vomiting. Immediately con-
tact a poison control center or a
physician.
• Avoid inhaling coolant mist or hot
vapors. If inhaled, remove to a
fresh air area.
• If coolant gets in the eyes, flush
with water and seek medical atten-
tion.
• Wash thoroughly after handling
coolant.
• Keep engine coolant out of the
reach of children and pets.

8-14
EMERGENCY SERVICE
75RM4-01E
If the high engine coolant temperature
warning light does not go off:
1) Turn off the engine and check that thewater pump belt and pulleys are not
damaged or slipping. If any abnormality
is found, correct it.
2) Check the coolant level in the reservoir. If it is found to be lower than “LOW”
line, check radiator, water pump, radia-
tor hoses and heater hoses for leakage.
If leakage that may cause overheating
is found, do not run the engine until
these problems have been corrected.
3) If leakage is not found, carefully add
coolant to the reservoir and then the
radiator, if necessary. (Refer to “Engine
coolant” in the “INSPECTION AND
MAINTENANCE” section.)
NOTE:
If engine overheats and you are not sure
what to do, contact your SUZUKI dealer.
79J007
WA R N I N G
• It is hazardous to remove the radia- tor cap (or degassing tank cap for a
diesel engine) when the water tem-
perature is high, because scalding
fluid and steam may be blown out
under pressure. The cap should
only be taken off when the coolant
temperature has lowered.
• To help prevent personal injury, keep hands, tools and clothing
away from the engine cooling fan
and air-conditioner fan (if
equipped). These electric fans can
automatically turn on without warn-
ing.
