Maintenance
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
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.
It 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.
Brake fluid
Check brake fluid level in the brake
fluid reservoir. The level should be
between “MIN” and “MAX” marks on
the side of the reservoir. Use only
hydraulic brake fluid conforming to
DOT 3 or DOT 4 specification.
Parking brake
Inspect the parking brake system
including the parking brake pedal
and cables.
Brake discs, pads, calipers
and rotors
Check the pads for excessive wear,
discs for run out and wear, and
calipers for fluid leakage.
Exhaust pipe and muffler
Visually inspect the exhaust pipes,
muffler and hangers for cracks, dete-
rioration, or damage. Start the
engine and listen carefully for any
exhaust gas leakage. Tighten con-
nections or replace parts as neces-
sary.
Suspension mounting bolts
Check the suspension connections
for looseness or damage. Retighten
to the specified torque.
