Kia Telluride 2023 Owner's Manual page 455

Maintenance
Valve clearance (if equipped)
Inspect for excessive valve noise and/or
engine vibration and adjust if necessary.
An authorized Kia dealer should perform
the operation.
Cooling system
Check the cooling system components,
such as the 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 maintenance
schedule.
Automatic transmission (AT) fluid
Automatic transmission fluid should not
be checked under normal usage condi-
tions. 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 malfunction and
failure. Use only specified automatic
transmission fluid. (Refer to "Recom-
Explanation of scheduled maintenance items
mended lubricants and capacities" on
page 9-5.)
Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and any
leakage. Replace any deteriorated or
damaged parts immediately.
NOTICE
NHTSA Safety Corrosion Alert
NHTSA has warned all vehicle owners 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
chemicals. While serious corrosion con-
ditions typically only manifest them-
selves as safety issues after 7 years of
vehicle use, the corrosion process starts
immediately and thus underbody clean-
ing maintenance 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 vehi-
cle 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 regular profes-
sional 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 assem-
bly if you find severe corrosion that
causes scaling or flaking of brake
components.
