Normal Heating (Using outside air)
Move the function lever/knob to “HEAT” and
the air intake lever to “FRESH AIR”, the
temperature control lever/knob to the desired
temperature position, and the fan switch to
the desired fan speed position. Moving the
fan switch to a higher fan speed position
increases heating efficiency.

Quick Heating (Using recirculated air)
The lever/knob settings are the same as for
normal heating except you move the air
intake lever to “RECIRCULATED AIR”. If
you use this heating method for an
extended period of time, the air in the
vehicle can become contaminated and the
windows can become misty. Therefore, use
this method only for quick heating and
change to the normal heating method as
soon as possible.
Cool Face/Warm Feet
Move the function lever/knob to “BI-LEVEL”
and the air intake lever to “FRESH AIR”,
the temperature control lever/knob to the
desired temperature position, and the fan
switch to the desired fan speed position.
Unless the temperature control lever is in
the fully “COOL” 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.

Defrosting
Move the function lever/knob to “DEFROST”
and the air intake lever to “FRESH AIR”,
the temperature control lever/knob to the
desired temperature position, and the fan
switch to “HIGH” Moving the temperature
control lever/knob to a higher temperature
position increases defrosting efficiency.
When the windscreen has become clear,
move the fan switch to the desired fan
speed position.
AIR CONDITIONING SYSTEM
(if equipped)If your vehicle is equipped with air
conditioner, it has an A/C button located on
the heater control panel. The air conditioning
system can be used to provide cooling and
dehumidifying, as described below. To turn
on the air conditioning system, push in the
A/C button and move the fan switch to a
position other than “OFF”. An indicator light
will come on when the air conditioning
system is on. To turn off the air conditioning
system, push the A/C button again.
During operation of the air conditioner, you
may notice slight changes in engine speed.
These changes are normal, the system is
designed so that the compressor turns on
or off to maintain the desired temperature.
Less operation of the compressor results in
better fuel economy.

SYSTEM OPERATING INSTRUCTIONSNormal Cooling (using outside air)
Push in the A/C button, move the function
lever/knob to "VENTILATION", the air
intake lever to “FRESH AIR”, the
temperature control lever/knob to the
“COOL” position, and the fan switch to the
desired fan speed position. Moving the fan
switch to a higher fan speed position
increases cooling efficiency.
If the ambient temperature is high enough
to cause insufficient cooling, use the "Quick
Cooling" as following.

Quick Cooling (Using recirculated air)
The lever/knob settings are the same as for
normal cooling except you move the air
intake lever to “RECIRCULATED AIR”. If
you use this cooling method for a extended
period of time, the air in the vehicle can
become contaminated. Therefore, you
should occasionally move the air intake
lever to “FRESH AIR”.NOTE:
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 lever
at “FRESH AIR” and the fan at high speed.
Dehumidifying
Push in the A/C button, move the function
lever/knob to the desired function position,
the air intake lever to “FRESH AIR”, the
temperature control lever/knob to the desired
temperature position, and the fan switch to
the desired fan speed position.NOTE:
Because the air conditioner dehumidifies the
air, turning it on will help keep the windows
clear, even when blowing heated air using
the DEMIST or HEATER & DEMIST
functions.

(ALTO / ALTO K10)Maintenance
If you do not use the air conditioner for a
long period, such as during winter, it may
not give the best performance when you
start using it again. To help maintain op-
timum performance and durability of your air
conditioner, it needs to be run periodically.
Operate the air conditioner at least once a
month for one minute with the engine idling.
This circulates the refrigerant and oil and
helps protect the internal components.
Note:
Your vehicle uses the air conditioning re-
frigerant HFC-134a, commonly called “R-
134a”. Only R-134a should be used in your
vehicle.
CAUTION
Using the wrong refrigerant may dam-
age your air conditioning system. Use
R-134a only. Do not mix or replace the
R-134a with other refrigerants.

Refilling
Remove the oil filler cap and pour oil slowly
through the filler hole to bring the oil level
to the upper limit on the dipstick. Be careful
not to overfill. Too much oil is almost as
bad as too little oil. After refilling, start the
engine and allow it to idle for about a
minute. Stop the engine, wait for five
minutes and check the oil level again.
Changing Engine Oil and Filter
Drain the engine oil while the engine is still
warm.
1) Remove the oil filler cap.
2) Place a drain pan under the drain plug.
3) Using the correct spanner remove the
drain plug and drain out the engine oil.
The engine oil temperature may be high
enough to burn your fingers when the
drain plug is loosened. Wait until the
drain plug is cool enough to touch with
your bare hands.

w WARNING
New and used oil can be hazardous.
Children and pets may be harmed by
swallowing new or used oil. Keep new
and used oil and used oil filters away
from children and pets.
Continuous contact with used engine
oil may cause (skin) cancer.
Brief contact with used oil may irritate
skin.
To minimize your exposure to used
oil, wear a long-sleeve shirt and
moistureproof gloves (such as
dishwashing gloves) when changing
oil. If oil contacts your skin, wash
thoroughly with soap and water.
Launder any clothing or rags if wet
with oil.
Recycle or properly dispose of used
oil and filters.
4. Reinstall the drain plug and new gasket.
Tighten the plug with a wrench to the
specified torque.

Specified Manual Transmission oil
When adding gear oil, use the appropriate
viscosity and grade as shown in the chart
below. We highly recommend you use API
GL-4 SAE 75W-90 (1) gear oil.
Type of oil Gear oil, API GL-4
Gear oil level check
To check the gear oil level, use the
following procedure:
1) Park the vehicle on a level surface with
the parking brake applied. Then, stop the
engine.
2) Clean casing around oil filler plug to
remove risk of any loose dirt or debris
entering oil filler plug hole. Remove the
oil filler plug 1.
3) Feel the inside of the hole with your
finger. If the oil level comes up to the
bottom of the plug hole, the oil level is
correct. If so, reinstall the plug.
4) If the oil level is low, add gear oil
through the filler plug hole 1 until the
oil level reaches the bottom of the filler
hole, then reinstall the plug.After driving the vehicle, the
transmission oil temperature may be
high enough to burn you. Wait until
the oil filler plug is cool enough to
touch with your bare hands before
inspecting transmission oil.
When tightening the plug, apply
sealing compound to the plug threads
to prevent oil leakage.
Gear oil change
Since special procedures, materials and
tools are required, it is recommended that
you trust this job to your authorized
MARUTI SUZUKI dealer.
