Maintenance
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 dam-
age.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.
CHECKING FLUID LEVELS

725
Maintenance
BRAKE FLUID
Checking the brake fluid level
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX (Maximum) and MIN
(Minimum) marks on the side of the
reservoir.
Before removing the reservoir cap
and adding brake fluid, clean the
area around the reservoir cap thor-
oughly to prevent brake fluid contam-
ination.If the level is low, add fluid to the
MAX (Maximum) level. The level will
fall with accumulated mileage. This is
a normal condition associated with
the wear of brake linings. If the fluid
level is excessively low, have the
brake system checked by an author-
ized Kia dealer.
Use only the specified brake fluid.
(Refer to “Recommended lubricantsand capacities” in chapter 8.)
Never mix different types of fluid.
In the event the brake system
requires frequent additions of fluid,
the vehicle should be inspected by
an authorized Kia dealer.
When changing and adding brake
fluid, handle it carefully. Do not let it
come in contact with your eyes. If
brake fluid should come in contact
with your eyes, immediately flush
them with a large quantity of fresh
tap water. Have your eyes examined
by a doctor as soon as possible.
Brake fluid, which has been exposed
to open air for an extended time
should never be used as its quality
cannot be guaranteed. It should be
disposed of properly.
OJFH075166CAUTION - Brake fluid
Do not allow brake fluid to con-tact the vehicle's body paint, aspaint damage will result.
CAUTION - Proper fluid
Only use brake fluid in the brakesystem. Small amounts ofimproper fluids (such as engineoil) can cause damage to thebrake system.

Maintenance
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.
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 cor-
rosion. Immediately seek an inspection of
your vehicle if you become visually
aware of corrosion flaking or scal-
ing or if you become aware of a
change in vehicle performance,
such as soft or spongey brakes,
fluids leaking, impairment of direc-
tional control, suspension noises
or rattling metal straps.
Aluminum wheel maintenance
The aluminum wheels are coated
with a clear protective finish.
Do not use any abrasive cleaner,polishing compound, solvent, or
wire brushes on aluminum wheels.
They may scratch the finish.
Clean the wheel when it has cooled.
Use only a mild soap or neutral detergent, and rinse thoroughly with
water. Also, be sure to clean the
wheels after driving on salted roads.
This helps prevent corrosion.
Avoid washing the wheels with highspeed vehicle wash brushes.
Do not use any alkaline or acid detergents It may damage and cor-
rode the aluminum wheels coated
with a clear protective finish.

RECOMMENDED LUBRICANTS AND CAPACITIES
To help achieve proper engine and powertrain performance and durability, use only lubricants of the proper quality.
The correct lubricants also help promote engine efficiency that results in improved fuel economy.
These lubricants and fluids are recommended for use in your vehicle.
*1Refer to the recommended SAE viscosity numbers on the next page.
*2Engine oils labeled Energy Conserving Oil are now available. Along with other additional benefits, they contribute to fuel econo my by reducing
the amount of fuel necessary to overcome engine friction. Often, these improvements are difficult to measure in everyday driving, but in a year’s
time, they can offer significant cost and energy savings.
