ENGINE OIL
Checking the engine oil level
1. Be sure the vehicle is on level
ground.
2. Start the engine and allow it to reach normal operating tempera-
ture.
3. Turn the engine off and wait for a few minutes (about 5 minutes) for
the oil to return to the oil pan.
4. Pull the dipstick out, wipe it clean, and reinsert 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.
Use a funnel to help prevent oil
from being spilled on engine com-
ponents.
Use only the specified engine oil. (Refer to “Recommended lubricantsand capacities” in chapter 8.)
CAUTION - Replacing
engine oil
Do not overfill the engine oil. Itmay damage the engine.
WARNING- Radiator hose
Be very careful not to touch the
radiator hose when checking or
adding the engine oil as it may
be hot enough to burn you.

BRAKE FLUID
Checking the brake fluid level
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX (Maximum) and MIN
(Minimum) marks on the side of the
reservoir.
Before removing the reservoir cap
and adding brake fluid, clean the
area around the reservoir cap thor-
oughly to prevent brake fluid contam-
ination.If the level is low, add fluid to the
MAX (Maximum) level. The level will
fall with accumulated mileage. This is
a normal condition associated with
the wear of brake linings. If the fluid
level is excessively low, have the
brake system checked by an author-
ized Kia dealer.
Use only the specified brake fluid.
(Refer to “Recommended lubricantsand capacities” in chapter 8.)
Never mix different types of fluid.
In the event the brake system
requires frequent additions of fluid,
the vehicle should be inspected by
an authorized Kia dealer.
When changing and adding brake
fluid, handle it carefully. Do not let it
come in contact with your eyes. If
brake fluid should come in contact
with your eyes, immediately flush
them with a large quantity of fresh
tap water. Have your eyes examined
by a doctor as soon as possible.
Brake fluid, which has been exposed
to open air for an extended time
should never be used as its quality
cannot be guaranteed. It should be
disposed of properly.
OJFH075166CAUTION - Brake fluid
Do not allow brake fluid to con-tact the vehicle's body paint, aspaint damage will result.
CAUTION - Proper fluid
Only use brake fluid in the brakesystem. Small amounts ofimproper fluids (such as engineoil) can cause damage to thebrake system.

Temperature -A, B & C
The temperature grades are A (the
highest), B and C representing the
tire’s resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled condi-
tions on a specified indoor laboratory
test wheel.
Sustained high temperature can
cause the material of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure. Grades B and A
represent higher levels of perform-
ance on the laboratory test wheel
than the minimum required by law. Tire terminology and definitions
Air Pressure:
The amount of air
inside the tire pressing outward on
the tire. Air pressure is expressed in
kilopascal (kPa) or pounds per
square inch (psi).
Accessory Weight: This means the
combined weight of optional acces-
sories. Some examples of optional
accessories are, automatic transmis-
sion, power seats, and air condition-
ing.
Aspect Ratio: The relationship of a
tire's height to its width.
Belt: A rubber coated layer of cords
that is located between the plies and
the tread. Cords may be made from
steel or other reinforcing materials.
Bead: The tire bead contains steel
wires wrapped by steel cords that
hold the tire onto the rim.
Bias Ply Tire: A pneumatic tire in
which the plies are laid at alternate
angles less than 90 degrees to the
centerline of the tread. Cold Tire Pressure:
The amount of
air pressure in a tire, measured in
kilopascals (kPa) or pounds per
square inch (psi) before a tire has
built up heat from driving.
Curb Weight: This means the weight
of a motor vehicle with standard and
optional equipment including the
maximum capacity of fuel, oil and
coolant, but without passengers and
cargo.
DOT Markings: The DOT code
includes the Tire Identification
Number (TIN), an alphanumeric des-
ignator which can also identify the
tire manufacturer, production plant,
brand and date of production.
