Maintenance
Check the condition and connections
of all cooling system hoses and
heater hoses. Replace any swollen
or deteriorated hoses.
The coolant level should be filled
between F and L marks on the
coolant level gauge when the engine
is cool.
If the coolant level is low, add enough
specified coolant to provide protec-
tion against freezing and corrosion.
Bring the level to F, but do not over-
fill. If frequent additions are required,
see an authorized Kia dealer for a
cooling system inspection.
✽ ✽NOTICE
Make sure the coolant cap is proper-
ly closed after refill of coolant.
Otherwise the engine could be over-
heated while driving.
1. Check if the radiator cap label is
straight In front.WARNING- Cooling fan
Use caution when
working near the
blade of the cooling
fan. The electric
motor (cooling fan) is
controlled by engine coolant
temperature, refrigerant pres-
sure and vehicle speed. it may
sometimes operate even when
the engine is not running.

2. Make sure that the tiny protru-
sions inside the coolant cap
should be securely interlocked.
Recommended engine coolant
When adding coolant, use only
deionized water or soft water for
your vehicle and never mix hard
water in the coolant filled at the fac-
tory. An improper coolant mixture
can result in serious malfunction or
engine damage.
The engine in your vehicle has alu- minum engine parts and must be
protected by an ethylene-glycol
with phosphate based coolant to
prevent corrosion and freezing.
DO NOT USE alcohol or methanol coolant or mix them with the spec-
ified coolant.
Do not use a solution that contains more than 60% antifreeze or less
than 35% antifreeze. This would
reduce the effectiveness of the
solution. For mixture percentage, refer to the
following table.

Maintenance
Changing the coolant
Have the coolant changed by an
authorized Kia dealer according to
the Maintenance Schedule at the
beginning of this chapter.
WARNING
Radiator cap
Do not remove the radiator cap
when the engine and radiator
are hot. Scalding hot coolant
and steam may blow out under
pressure which may result in
serious injury.
CAUTION
Put a thick cloth or fabricaround the radiator cap beforerefilling the coolant in order toprevent the coolant from over-flowing into engine parts suchas the generator.

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.
CAUTION - 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 brakesystem. Small amounts ofimproper fluids (such as engineoil) can cause damage to thebrake system.

If the vehicle is operated in extreme-
ly dusty or sandy areas, replace theelement more often than the usualrecommended intervals. (Refer to“Maintenance under severe usageconditions” in this chapter.)

and hold the switch more than 2 sec-
onds until the wiper blade is in the
fully up position.1. Raise the wiper arm.

Maintenance
Recharging the battery
Your vehicle has a maintenance-free,
calcium-based battery.
If the battery becomes dischargedin a short time (because, for exam-
ple, the headlamps or interior
lamps were left on while the vehi-
cle was not in use), recharge it by
slow charging (trickle) for 10 hours.
If the battery gradually discharges because of high electric load while
the vehicle is being used, recharge
it at 20-30A for two hours. When recharging the battery,
observe the following precautions:
The battery must be removed from
the vehicle and placed in an area
with good ventilation.
Do not allow cigarettes, sparks, or flame near the battery.
Watch the battery during charging, and stop or reduce the charging
rate if the battery cells begin
gassing (boiling) violently or if the
temperature of the electrolyte of
any cell exceeds 49°C (120°F).
Wear eye protection when check- ing 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. Before performing maintenance or
recharging the battery, turn off all
accessories and stop the engine.
The negative battery cable must be removed first and installed last
when the battery is disconnected.
