Maintenance
Vacuum crankcase ventilation
hoses
Inspect the surface of hoses for evi-
dence of heat and/or mechanical
damage. Hard and brittle rubber,
cracking, tears, cuts, abrasions, and
excessive swelling indicate deterio-
ration. Particular attention should be
paid to examine those hose surfaces
nearest to high heat sources, such
as the exhaust manifold.
Inspect the hose routing to assure
that the hoses do not come in con-
tact with any heat source, sharp
edges or moving component which
might cause heat damage or
mechanical wear. Inspect all hose
connections, such as clamps and
couplings, to make sure they are
secure, and that no leaks are pres-
ent. Hoses should be replaced
immediately if there is any evidence
of deterioration or damage.
Air cleaner filter
A Genuine Kia air cleaner filter is
recommended when the filter is
replaced.
Spark plugs
Make sure to install new spark plugs
of the correct heat range.
Valve clearance
Inspect excessive valve noise and/or
engine vibration and adjust if neces-
sary. An authorized Kia dealer
should perform the operation.
Cooling system
Check cooling system components,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Coolant
The engine and inverter coolant
should be changed at the intervals
specified in the maintenance sched-
ule.

PARKING BRAKE
Checking the parking brake
Check whether the stroke is within
specification when the parking brake
pedal is depressed with 44 lb (20 kg,
196 N) of force. Also, the parking
brake alone should securely hold the
vehicle on a fairly steep grade.

BATTERY
For best battery service
Keep the battery securely mount-ed.
Keep the battery top clean and dry.
Keep the terminals and connec- tions clean, tight, and coated with
petroleum jelly or terminal grease.
Rinse any spilled electrolyte from the battery immediately with a
solution of water and baking soda.
If the vehicle is not going to be used for an extended time, discon-
nect the battery cables.
WARNING - Risk of
explosion
Keep Lit cigarettes and all other flames or
sparks away from the
battery.
The battery contains hydrogen -- a highly
combustible gas, which
will explode if it comes
in contact with a flame or
spark.WARNING - Sulfuric acid
in batteries
Keep batteries out of the reach of children
because batteries con-
tain highly corrosive
SULFURIC ACID and
electrolytes. Do not
allow battery acid to
contact your skin, eyes,
clothing or paint finish.
Wear eye protection when charging or work-
ing near a battery.
Always provide ventila-
tion when working in an
enclosed space.
