Maintenance
(Continued)
• Use professional service techni-cians or governmental inspection
stations to annually inspect for
corrosion.
• Immediately seek an inspection of your vehicle if you become visual-
ly aware of corrosion flaking or
scaling or if you become aware of
a change in vehicle performance,
such as soft or spongy brakes, flu-
ids leaking, impairment of direc-
tional control, suspension noises
or rattling metal straps. NHTSA
further advises that after a vehicle
is 7 years old, it is essential that
you take these indicated mainte-
nance steps to ensure that you pro-
tect yourself from unsafe corro-
sion conditions.Owner maintenance precau-
tions
Improper or incomplete service may
result in problems. This section gives
instructions only for the maintenance
items that are easy to perform.
As explained earlier in this section,
several procedures can be done only
by an authorized K900 Kia dealer
with special tools.
✽ NOTICE
Improper owner maintenance dur-
ing the warranty period may affect
warranty coverage. For details, read
the separate Warranty &
Maintenance book provided with
the vehicle. If you're unsure about
any servicing or maintenance proce-
dure, have it done by an authorized
K900 Kia dealer.
Maintenance work
Do not wear jewelry or loose
clothing while working under
the hood of your vehicle with
the engine running. These can
become entangled in moving
parts, if you must run the
engine while working under the
hood, make certain that you
remove all jewelry (especially
rings, bracelets, watches, and
necklaces) and all neckties,
scarves, and similar loose
clothing before getting near the
engine or cooling fans.

Maintenance
Cooling system
Check cooling system components,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Automatic transaxle fluid
Automatic transaxle fluid should not
be checked under normal usage
conditions.
But in severe conditions, the fluid
should be changed at an authorized
K900 Kia dealer in accordance to the
scheduled maintenance at the begin-
ning of this chapter.
✽NOTICE
Automatic transaxle fluid color is
basically red.
As the vehicle is driven, the auto-
matic transaxle fluid will begin to
look darker.
This is normal condition and you
should not judge the need to replace
the fluid based upon the changed
color.
Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and
any leakage. Replace any deteriorat-
ed or damaged parts immediately.
✽NOTICE
■ NHTSA Safety Corrosion
Alert
NHTSA has warned all vehicle own-
ers of all brands that they must
maintain their vehicles in a manner
which will prevent brake hose and
brake line failures due to corrosion
when such vehicles are exposed to
winter road salt and related chemi-
cals. While serious corrosion condi-
tions typically only manifest them-
selves as safety issues after 7 years of
vehicle use, the corrosion process
starts immediately and thus under-
body cleaning maintenance must
commence from your vehicle's first
exposure to road salts and chemi-
cals. (Continued)
The use of a non-specified fluid
could result in transmission
malfunction and failure.
Use only specified automatic
transmission fluid. (Refer to
“Recommended lubricants and
capacities” in section 8.)

Maintenance
ENGINE COOLANT
The high-pressure cooling system
has a reservoir filled with year-round
antifreeze coolant. The reservoir is
filled at the factory.
Check the antifreeze protection and
coolant level at least once a year, at
the beginning of the winter season,
and before traveling to a colder cli-
mate. Checking the coolant level Turn the engine off and wait until itcools down. Use extreme care
when removing the radiator cap.
Wrap a thick towel around it, and
turn it counterclockwise slowly to
the first stop. Step back while the
pressure is released from the cool-
ing system.
When you are sure all the pressure
has been released, press down on
the cap, using a thick towel, and
continue turning counterclockwise
to remove it.
Even if the engine is not operating, do not remove the radiator cap or
the drain plug while the engine and
radiator are hot. Hot coolant and
steam may still blow out under
pressure, causing serious injury.
Removing radia-
tor cap
Never attempt to remove the
radiator cap while the engine is
operating or hot. Doing so
might lead to cooling system
and engine damage and could
result in serious personal injury
from escaping hot coolant or
steam.

7-35
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 side
of the coolant reservoir when the
engine is cool.If the coolant level is low, add enough
distilled (deionized) water. Bring the
level to F, but do not overfill. If fre-
quent additions are required, see an
authorized K900 Kia dealer for a
cooling system inspection.
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. If
your vehicle is equipped with
GDI, the electric motor (cooling
fan) may operate until you dis-
connect the negative battery
cable.
