If the belt is too loose, insufficient battery
charging, engine overheating, poor power
steering, poor air conditioning, or exces-
sive belt wear can result. When you press
the belt with your thumb midway between
the pulleys, there should be a deflection
according to the following chart.
The belts should also be examined to
ensure that they are not damaged.

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.
The handle of the engine oil dipstick is col-
ored with yellow for easy identification.
NOTICE
Use only the recommended ACEA
C2. Use of non-recommended engine
oil will cause damage to a diesel
engine and DPF
®.

INSPECTION AND MAINTENANCE
54P00-01E
Pull out the oil dipstick, wipe oil off with a
clean cloth, insert the dipstick all the way
into the engine, and 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.NOTE:
When the soot particles accumulated in
the DPF
® are combusted, the amount of
the engine oil may increase due to the dilu-
tion with the fuel. This is not a vehicle mal-
function. The soot particles accumulated in
the DPF
® are combusted automatically
during driving. However, they may not be
combusted in the following cases.
• When you drive at low speed for a long
time
• When you repeat a short-time or short-
distance driving
1) When the DPF
® warning light comes
on, drive at a speed of 50 km/h (31
mph) or higher for more than 25 min-
utes to regenerate the DPF
® properly.
For details, refer to “Diesel particulate
filter (DPF
®)” in “OPERATING YOUR
VEHICLE” section.
2) When the oil change request light
blinks, change the engine oil and oil fil-
ter, and reset the oil life monitoring sys-
tem. To reset the oil life monitoring
system, consult your SUZUKI dealer.
3) When the engine oil level exceeds the
MAX level on the dipstick, consult your
SUZUKI dealer.
Refilling
81A147
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 the oil. Too much oil is almost
as bad as too little oil. After refilling, start the
engine and allow it to idle for about a min-
ute. Stop the engine, wait about 5 minutes
and check the oil level again.
NOTICE
Failure to check the oil level regularly
could lead to serious engine trouble
due to insufficient oil.
NOTICE
(For diesel engine model)
Do not top up the oil over the MAX
limit. Too much oil causes serious
engine trouble.

utes. Check the oil level again and add
oil if necessary. Check for leakage
again.
Engine coolant
Selection of coolant
To maintain optimum performance and
durability of your engine, use SUZUKI gen-
uine coolant or equivalent.
NOTE:
If you replace the engine coolant with cool-
ant other than “SUZUKI LLC: Super
(Blue)”, follow the schedule of “SUZUKI
LLC: Standard (Green)”. To see the detail
of the maintenance schedule, refer to
“Maintenance schedule” in this section.
This type of coolant is the best for cooling
system for the following reasons:
• The coolant helps maintain proper
engine 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 authorizedSUZUKI dealer can help you select the
proper coolant.
NOTICE
• When replacing the oil filter, it is
recommended that you use a genu-
ine SUZUKI replacement filter. If
you use an aftermarket filter, check
that it is of equivalent quality and
follow the manufacturer’s instruc-
tions.
• Oil leakage from the periphery of
the oil filter or drain plug indicate
incorrect installation or gasket
damage. If you find any leakage or
are not sure that the filter has been
properly tightened, have the vehi-
cle inspected by your SUZUKI
dealer.
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 distilled 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 damage.

Coolant level check
Check the coolant level at the reservoir
tank, not at the radiator. With the engine
cool, the coolant level should be between
“FULL” and “LOW” marks.
Adding coolant
(For gasoline engine model)
61MM2A001
If the coolant level is below “LOW” mark,
more coolant should be added. Remove
the reservoir tank cap and add coolant until
the reservoir tank level reaches “FULL”
mark. Never fill the reservoir tank above
“FULL” mark.
(For diesel engine model)

WA R N I N G
Engine coolant is harmful or fatal if
swallowed or inhaled. Do not drink
antifreeze or coolant solution. If swal-
lowed, do not induce vomiting. Imme-
diately contact a poison control
center or a physician. Avoid inhaling
mist or hot vapors; if inhaled, exhale
and move to where there is fresh air.
If coolant gets in eyes, flush eyes
with water and seek medical atten-
tion. Wash thoroughly after handling.
Solution can be poisonous to ani-
mals. Keep out of the reach of chil-
dren and animals.
NOTICE

may result in the possibility of freez-
ing and/or overheating coolant.
NOTICE
“SUZUKI LLC: Standard (Green) cool-
ant”;
• The mixture you use should con-
tain 50% concentration of anti-
freeze.
• If the lowest ambient temperature
in your area is expected to be –35°C
(–31°F) or below, use higher con-
centrations up to 60% following the
instructions on the antifreeze con-
tainer.

INSPECTION AND MAINTENANCE
54P00-01E
If the coolant level is below “LOW” mark,
more coolant should be added. When the
engine is cool, remove the degassing tank
cap by turning it counterclockwise slowly to
release any pressure. And add coolant
until the degassing tank level reaches
“FULL” mark. Never fill the degassing tank
above “FULL” mark.
Coolant replacement
Since special procedures are required, ask
your authorized SUZUKI dealer for this job.
Air cleaner
If the air cleaner is clogged with dust, there
will be greater intake resistance, resulting
in decreased power output and increased
fuel consumption.
(For gasoline engine model)
61MM0B063
1) Remove the air cleaner inlet hose (1).
2) Remove the bolts (2), loosen the bolt
(3) and lift the air cleaner case (4)

3) Unclamp the side clamps, and remove
the element from the air cleaner case. If
it appears to be dirty, replace it with a
new one.
4) Clamp the side clamps or tighten the
bolts securely.
WA R N I N G
It is hazardous to remove the reser-
voir tank cap (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. Wait until the coolant
temperature has lowered before
removing the cap.
NOTICE
