Maintenance
DRIVE BELTSDrive belts should be checked periodical-
ly for proper tension and replaced if nec-
essary. At the same time, belts should be
examined for cracks, wear, fraying or
other evidence of deterioration and
replaced if necessary.
Belt routing should also be checked to be
sure there is no interference between the
belts and other parts of the engine.
If the belt is too loose, have it replaced by
an authorized Kia dealer.Checking the compressor drive
beltHave the drive belts checked in accor-
dance with the maintenance schedule.
Checking the power steering fluid
level With the vehicle on level ground, check
the fluid level in the power steering reser-
voir periodically. The fluid should be
between MAX and MIN marks on the
side of the reservoir at the normal tem-
perature.
Before adding power steering fluid, thor-
oughly clean the area around the reser-
voir cap to prevent power steering fluid
contamination.
If the level is low, add fluid to the MAX
level.In the event the power steering system
requires frequent addition of fluid, the
vehicle should be inspected by an
authorized Kia dealer.
✽ ✽
NOTICE• To avoid damage to the power steer-
ing pump, do not operate the vehicle
for prolonged periods with a low
power steering fluid level.
• Never start the engine when the reser- voir tank is empty.
• When adding fluid, be careful that dirt does not get into the tank.
• Insufficient fluid can result in increased steering effort; excessive
noise may also be present as the steer-
ing wheel is turned.
• The use of the non-specified fluid could reduce the effectiveness of the
power steering wheel and cause dam-
age to it.Use only the specified power steering
fluid. (Refer to "Recommended Lubricants" later in this section.)Power steering hoseCheck the hoses and hose connections
for leaks or damage before driving the
vehicle.

Wheel replacement When replacing the metal wheels for
any reason, make sure the new
wheels are equivalent to the original
factory units in diameter, rim width
and offset.
WARNING -
Replacing
tires
 Driving on worn-out tires is very hazardous and will
reduce braking effectiveness,
steering accuracy, and trac-
tion.
 Your vehicle is equipped with tires designed to provide for
safe ride and handling capa-
bility. Do not use a size and
type of tire and wheel that is
different from the one that is
originally installed on your
vehicle. It can affect the safety
and performance of your vehi-
cle, which could lead to han-
dling failure or rollover and
serious injury. When replacing
the tires, be sure to equip all
four tires with the tire and
wheel of the same size, type,
tread, brand and load-carrying
capacity.
(Continued)
(Continued)If you nevertheless decide to
equip your vehicle with any
tire/wheel combination not
recommended by Kia for off
road driving, you should not
use these tires for highway
driving.
 The use of any other tire size or type may seriously affect
ride, handling, ground clear-
ance, stopping distance, body
to tire clearance, snow tire
clearance, and speedometer
reliability.
 It is best to replace all four tires at the same time. If that is
not possible, or necessary,
then replace the two front or
two rear tires as a pair.
Replacing just one tire can
seriously affect your vehicle’s
handling.
WARNING
A wheel that is not the correct
size may adversely affect wheel
and bearing life, braking and
stopping abilities, handling char-
acteristics, ground clearance,
body-to-tire clearance, snow
chain clearance, speedometer
calibration, headlight aim and
bumper height.

LUBRICANT SPECIFICATIONSRecommended lubricants 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.
Engine oils labeled Energy Conserving Oil are now available.
Along with other additional benefits, they contribute to fuel
economy by reducing the amount of fuel necessary to over-
come 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.
Recommended SAE viscosity number ✽ ✽NOTICEAlways be sure to clean the area around any filler plug, drain
plug, or dipstick before checking or draining any lubricant.
This is especially 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. Engine oil viscosity (thickness) has an effect on fuel economy
and cold weather operating (starting and oil flow). Lower vis-
cosity engine oils can provide better fuel economy and cold
weather performance, however, higher viscosity engine oils are
required for satisfactory lubrication in hot weather. Using oils of
any viscosity other than those recommended could result in
engine damage.
When choosing an oil, consider the range of temperature your
vehicle will be operated in before the next oil change. Proceed
to select the recommended oil viscosity from the chart.
*¹ Refer to the recommended SAE viscosity numbers.These lubricants and fluids are recommended for use in your
vehicle.
