MAINTENANCE
7-12ENGINE OIL AND OIL
FILTERChecking the Engine Oil Level
1. Be sure the vehicle is on level
ground.
2. Start the engine and allow it to reach
normal operating temperature.
3. Turn the engine off and wait a few
minutes for the oil to return to the oil
pan.
4. Pull out the dipstick, wipe it clean,
and re-insert it fully.
5. Pull the dipstick out again and check
the level. The level should be
between F and L.
If it is near or at L, add enough oil to
bring the level to F. Do not overfill.
The distance between L and F on the
dipstick represents 0.85 US qt. (0.7 liter).
Use only the specified engine oil.(Refer to “Recommended Lubricants”
later in this section)
CHANGING THE ENGINE
OIL AND FILTERChange engine oil and filter according to
the Scheduled Maintenance earlier in this
section.
1. Warm the engine up for a few
minutes and then turn it off. Remove
the oil filler cap.
2. Drain the oil into a suitable container
after removing the oil filler cap and
drain plug.

WARNING - Engine Oil
 Continuous contact with
USED engine oil has caused
skin cancer in laboratory
mice. Protect your skin by
washing with soap and
water.
 Keep all engine oil out of the
reach of children.

3. Remove the engine oil filter with an
oil filter wrench.
4. Use a clean rag to clean the oil filter
mounting surface on the engine.
5. Apply a small amount of engine oil
to the new oil filter O-ring seal.6. Install the oil filter and tighten it.
(Refer to the oil filter caution label
for tightening instructions.)
7. Replace the drain plug tightly after
the oil has thoroughly drained.
8. Refill the engine with new oil to the
F mark on the dipstick. Do not
overfill.
9. Re-install the oil filler cap securely.
10. Start the engine and inspect around
the oil filter seal for leaks.
Stop the engine.
Check the oil level and fill to the F
mark, if necessary.
OIL CAPACITY
2400cc Engine
- Without filter change : 4.0 liters
- With filter change : 4.3 liters

2700cc Engine
- Without filter change : 4.5 liters
- With filter change : 4.8 liters
Use only the specified engine oil. (Refer
to “Recommended Lubricants” later in
this section)
CAUTION
Both the oil and engine are hot. Do
not burn yourself.✻
NOTICE
When installing the replacement oil
filter, do not allow the oil filter
gasket to remain on the oil filter
mounting surface. This will cause
oil leakage and engine damage.
Remove the old gasket completely
so that a new gasket will properly
seat and seal.
✻
NOTICE
• Follow these instructions
carefully. An improper oil filter
installation can cause oil leakage
and engine damage.
• Although oil filters may have the
same external appearance, their
internal designs differ
significantly. These filters are not
interchangeable. To avoid
potential engine damage, use only
the specified filter. Consult an
Authorized Kia Dealer.

TIRES AND WHEELSTIRE CAREFor proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tire
inflation pressures and stay within the
load limits and weight distribution
recommended for your vehicle.INFLATION PRESSURESCheck all tire pressures (including the
spare) monthly when the tires are cold.
“Cold tires” means the car has not been
driven for at least three hours or driven
less than one mile (1.6 km).
Recommended pressures must be
maintained to ensure ride quality, vehicle
handling, and minimum tire wear.
Watch the battery during
charging, and stop or reduce
the charging rate if the battery
cells begin gasing (boiling)
violently or if the temperature
of the electrolyte of any cell
exceeds 120°F (49°C).
Wear eye protection when
checking the battery during
charging.
Disconnect the battery
charger in the following
order.
1. Turn off the battery
charger main switch.
2. Unhook the negative
clamp from the negative
battery terminal.
3. Unhook the positive clamp
from the positive battery
terminal.
✻
NOTICE
• Before performing battery
maintenance or recharging, turn
OFF all accessories and stop the
engine.
• When remounted battery,
disconnect the negative (-)
battery cable first. When re-
installing the battery, reconnect
the negative (-) battery cable
last.

RECOMMENDED SAE
VISCOSITY NUMBEREngine oil viscosity (thickness) has an
effect on fuel economy and cold weather
operation (starting and oil flow). Lower
viscosity engine oils can provide better fuel
economy and cold weather performance,
however, higher viscosity engine oils are
required for satisfactory lubrication in hot
weather. Using oils of any viscosity other
than those recommended could result in
engine damage.
These lubricants and fluids are recommended for use in your vehicle.*1)
Refer to the recommended SAE viscosity numbers on the this page.
* Recommended for the Canadian climate.
Lubricant Classification
Engine oil* API Service SJ, SL or above,
ILSAC GF-3 or above
Manual transaxle oil* API Service GL-4 (SAE 75W-85)
Automatic trasaxle fluid SK ATF SP-III or Diamond ATF SP-III
Power steering fluid PSF-IV
Brake/clutch fluid SAEJ1703 or FMVSS116 DOT-3 DOT-4
✻
NOTICE
Always be sure to clean the area
around any filler plug, drain plug,
or dipstick before checking or
draining any lubricant. This is
especially important in dusty or
sandy areas and when the vehicle is
used on unpaved roads. Cleaning
the plug and dipstick areas will
prevent dirt and grit from entering
the engine and other mechanisms
that could be damaged.

MAINTENANCE
7-42HEADLIGHT AIMING
ADJUSTMENTBefore performing aiming adjustment,
make sure of the following.
1. Keep all tires inflated to the correct
pressure.
2. Place the vehicle on level ground and
press the front bumper & rear
bumper down several times.
3. See that the vehicle is unloaded
(except for full levels of coolant,
engine oil and fuel, and spare tire, jack,
and tools). Have the driver sit in the
driver’s seat or use equivalent weight.4. Clean the headlight lenses and turn
on the headlight (Low beam).
5. Open the hood.
6. Draw a vertical line (through the
center of each headlight) and the
horizontal line (through the center of
each headlight) on the aiming screen.
1) Horizontal line dimension from
ground: 628 mm (24.72 in)
2) Distance between each vertical
line : 1,306 mm (49.17 in)
And then, draw a parallel line at 30
mm (1.18 in) place under the
horizontal line.
7. Adjust each cut-off line of the low
beam to the parallel line with a
Phillips screwdriver.
ADJUSTMENT AFTER
HEADLIGHT ASSEMBLY
REPLACEMENTIf the vehicle has had front body repair
and the headlight assembly has been
replaced, the headlight aiming should be
checked using the aiming screen as
shown in the illustration. Turn on the
headlight switch. (Low Beam Position)
1. Adjust headlights so that main axis of
light is parallel to center line of the
body and is aligned with point “P”
shown in the illustration.
