w WARNING
The rear shock absorbers are filled with
high pressure gas. Never attempt to
disassemble it or throw it into a fire.
Avoid storing it near a heater or heating
device. When scrapping the absorber,
the gas must be released from the
absorber safely. Ask your dealer for
assistance. All maintenance should be carried out with
the ignition switch in the “OFF” position
and the car parked securely on the level
ground unless otherwise specified.
If you are in any way unsure of your
ability to undertake a task, then do not
start it but contact your MARUTI SUZUKI
dealer to perform the work for you.

Make sure the drive belt tension is correct.
If the belt is too loose, insufficient battery
charging, engine overheating, or excessive
belt wear can result. When you press the
belt with your thumb midway between the
pulleys, the belt deflection should be within
the specification below.
The belt should also be examined to ensure
that it is not damaged. If the belt needs to
be replaced or adjusted, have it done by
your MARUTI SUZUKI dealer.

INSPECTION AND MAINTENANCE9-11ENGINE OIL AND FILTERSpecified oil
Be sure that the engine oil you use comes
under the API classification of SF, SG or
SH. The recommended engine oil is SF
20W40 (1). Select the appropriate oil
viscosity according to the above chart.
Oil Level Check
It is important to keep the engine oil at the
correct level for proper lubrication of your
vehicle’s engine. Check the oil level with the
vehicle on a level surface. The oil level
indication may be inaccurate if the vehicle
is on a slope. The oil level should be
checked either before starting the engine or
at least 5 minutes after stopping the engine.
Pull out the oil dipstick, wipe oil off with a
clean cloth, insert the dipstick all the way
into the engine, then remove it again. The
oil on the stick should be between the
upper and lower limits shown on the stick.
If the oil level indication is near the lower
limit, add enough oil to raise the level to
the upper limit.
76G-09-00376G-09-004
(1) Preferred
Be sure that the engine oil you use comes
under the quality classification of SG+, SL
& SJ. Select the appropriate oil viscosity
according to the above chart.
SAE 5W30 (1) is the best choice for good
fuel economy, and good starting in cold
weather.
Failure to check the oil level regularly
could lead to serious engine trouble
due to insufficient oil.

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 thedrain 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.

INSPECTION AND MAINTENANCE9-13Replace the oil filter
1) Using an oil filter wrench, turn the oilfilter counterclockwise and remove it.
2) Using a clean rag, wipe off the mounting surface on the engine where the new
filter will be seated.
3) Smear a little engine oil around the rubber gasket of the new oil filter.
4) Screw on the new filter by hand until the filter gasket contacts the mounting
surface.
To tighten the oil filter properly, it is
important to accurately identify the
position at which the filter gasket
first contacts the mounting surface.
5. Tighten the filter specified turn from the point of contact with the mounting sur-
face (or to the specified torque) using an
oil filter wrench.
Tightening torque for oil filter
1 turn or
14 Nm (1.4 kg-m, 10.5 lb-ft)
CAUTION
Refill with oil and check for leaks.
1) Pour oil through the filler hole and install the filler cap.
For the approximate capacity of the oil,
refer to the "CAPACITIES" item in the
"SPECIFICATIONS" section.
2) Start the engine and look carefully for leaks at the oil filter and drain plug. Run
the engine at various speeds for at least
5 minutes.
3) Stop the engine and wait for 5 minutes. Check the oil level again and add oil if
necessary. Check for leaks again.
When replacing the oil filter, it is
recommended that you use a genuine
MARUTI replacement filter.
Oil leaks from around the oil filter or
drain plug indicate incorrect installa-
tion or gasket damage. If you find any
leaks or are not sure that the filter
has been properly tightened, have the
vehicle inspected by your MARUTI
SUZUKI dealer.
CAUTIONCAUTIONCAUTION

that the oil filter is tight, but do not
overtighten it.

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.
