Maintenance
Automatic transmission fluid
Automatic transmission fluid should
not be checked under normal usage
conditions. But in severe conditions,
the fluid should be changed at an
authorized Kia dealer in accordance
to the scheduled maintenance at
the beginning of this section.
NOTICE
Automatic transmission fluid color is
usually red. As the vehicle is driven,
the automatic transmission fluid will
begin to look darker.
It is the normal condition and you
should not judge the need to replace
the fluid based upon the changed
color.
CAUTION
Transmission fluids
The use of a non-specified fluid
could result in transmission mal-
function and failure. Use only speci-
fied automatic transmission fluid.
(Refer to "Recommended lubricants
and capacities" on page 8-6.)
Brake hoses and lines
Visually check for proper installa-
tion, chafing, cracks, deterioration
and any leakage. Replace any dete-
riorated or damaged parts immedi-
ately.
Explanation of scheduled maintenance items
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
themselves as safety issues after 7
years of vehicle use, the corrosion
process starts immediately and
thus underbody cleaning mainte-
nance must commence from your
vehicle's first exposure to road salts
and chemicals. NHTSA urges vehicle
owners to take the following steps
to prevent corrosion:
1. Wash the undercarriage of your
vehicle regularly throughout the
winter and do a thorough washing
in the spring to remove road salt
and other de-icing chemicals.
2. Monitor the brake system for
signs of corrosion by having regu-
lar professional inspections and
watching for signs of problems,
including loss of brake fluid,
unusual leaks and soft or spongy
feel in the brake pedal.
3. Replace the entire brake pipe
assembly if you find severe corro-
sion that causes scaling or flaking
of brake components.
