Maintenance
(Continued)
• Wash the undercarriage of yourvehicle regularly during the win-
ter and whenever your vehicle has
been exposed to such salts or
chemicals.
• Do a thorough washing of the undercarriage at the end of the
winter.
• 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 essen-
tial that you take these indicated
maintenance steps to ensure that
you protect yourself from unsafe
corrosion 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 Kia dealer with spe-
cial tools.
✽ ✽ NOTICE
Improper owner maintenance dur-
ing the warranty period may affect
warranty coverage. For details, read
the separate Warranty & Consumer
Information manual provided with
the vehicle. If you're unsure about
any servicing or maintenance proce-
dure, have it done by an authorized
Kia dealer.
WARNING- 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.
WARNING- Touching metal parts
Do not touch metal parts
(including strut bars) while the
engine is operating or hot.
Doing so could result in serious
bodily injury. Turn the engine off
and wait until the metal parts
cool down to perform mainte-
nance work on the vehicle.

Maintenance
Parking brake
Inspect the parking brake system
including the parking brake pedal
and cables.
Brake discs, pads, calipers
and rotors
Check the pads and discs for exces-
sive wear and calipers for fluid leak-
age.
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.
Steering gear box, linkage &
boots/lower arm ball joint
With the vehicle stopped and engine
off, check for excessive free-play in
the steering wheel.
Check the linkage for bends or dam-
age. Check the dust boots and ball
joints for deterioration, cracks, or
damage. Replace any damaged
parts.
Drive shafts and boots
Check the drive shafts, boots and
clamps for cracks, deterioration, or
damage. Replace any damaged
parts and, if necessary, repack the
grease.
Air conditioning refrigerant
Check the air conditioning lines and
connections for leakage and damage.When checking engine oil, engine
coolant, brake fluid, and washer fluid,
always be sure to clean the area
around any filler plug, drain plug, or
dipstick before checking or draining
any lubricant or fluid. This is espe-
cially important in dusty or sandy
areas and when the vehicle is used
on unpaved roads. Cleaning the plug
and dipstick areas will prevent dirt
and grit from entering the engine and
other mechanisms that could be
damaged.

Finish damage repair
Deep scratches or stone chips in the
painted surface must be repaired
promptly. Exposed metal will quickly
rust and may develop into a major
repair expense.
If your vehicle is damaged and
requires any metal repair or replace-
ment, be sure the body shop applies
anti-corrosion materials to the parts
repaired or replaced.
Bright-metal maintenance
To remove road tar and insects,
use a tar remover, not a scraper or
other sharp object.
To protect the surfaces of bright- metal parts from corrosion, apply a
coating of wax or chrome preser-
vative and rub to a high luster.
During winter weather or in coastal areas, cover the bright metal parts
with a heavier coating of wax or
preservative. If necessary, coat the
parts with non-corrosive petroleum
jelly or other protective compound.
Underbody maintenance
Road salt and other corrosive chemi-
cals are used in cold weather states to
melt snow and prevent ice accumula-
tion. If these chemicals are not regu-
larly removed, they will corrode the
vehicle underbody and over time dam-
age fuel lines, the fuel tank retention
system, the vehicle suspension, the
exhaust system, and even the body
frame. The National Highway Traffic
Safety Administration has warned all
vehicle owners of all brands of the
need to take the following steps:
Wash the undercarriage of yourvehicle regularly during the winter
and whenever your vehicle has
been exposed to such salts or
chemicals.CAUTION - Drying vehicle
Wiping dust or dirt off the body with a dry cloth willscratch the finish.
Do not use steel wool, abra- sive cleaners, acid detergentsor strong detergents contain-ing high alkaline or causticagents on chrome-plated oranodized aluminum parts.This may result in damage tothe protective coating andcause discoloration or paintdeterioration.
