4Power steering (if equipped)Power steering uses energy from the
engine to assist you in steering the vehi-
cle. If the engine is off or if the power
steering system becomes inoperative,
the vehicle may still be steered, but it will
require increased steering effort.
Should you notice any change in the
effort required to steer during normal
vehicle operation, have the power steer-
ing checked by an authorized Kia dealer.✽ ✽
NOTICE• Never hold the steering wheel against
a stop (extreme right or left turn) for
more than 5 seconds with the engine
running. Holding the steering wheel
for more than 5 seconds in either posi-
tion may cause damage to the power
steering pump.
• If the power steering drive belt breaks or if the power steering pump mal-
functions, the steering effort will
greatly increase.
✽ ✽ NOTICEIf the vehicle is parked for extended
periods outside in cold weather (below -
10 °C/14 °F), the power steering may
require increased effort when the engine
is first started. This is caused by
increased fluid viscosity due to the cold
weather and does not indicate a mal-
function.
When this happens, increase the engine
RPM by depressing the accelerator until
the RPM reaches 1,500 rpm then release
or let the engine idle for two or three
minutes to warm up the fluid.
Tilt and telescopic steering
(if equipped)A tilt and telescopic steering wheel
allows you to adjust the steering wheel
before you drive. You can also raise it to
the highest level to give your legs more
room when you exit and enter the vehi-
cle.
The steering wheel should be positioned
so that it is comfortable for you to drive,
while permitting you to see the instru-
ment panel warning lights and gauges.
STEERING WHEEL
WARNING -
Steering wheel
Never adjust the angle of steering
wheel while driving. You may lose
your steering control and cause
severe personal injury or acci-
dents.
 After adjusting, push the steering
wheel both up and down to be
certain it is locked in position.

 Lubricate door rubber weatherstrips.
 Check the air conditioning system before the warm weather season.
 Check the power steering fluid level.

Owner maintenance precautions 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, sev-
eral procedures can be done only by an
authorized Kia dealer with special tools.
Improper owner maintenance during
the warranty period may affect war-
ranty coverage. For details, read the
separate Kia Warranty & Consumer
Information Manual provided with the
vehicle. If you're unsure about any
servicing or maintenance procedure,
have it done by an Authorized Kia
Dealer.
WARNING
- Maintenance work
 Performing maintenance work on
a vehicle can be dangerous. You
can be seriously injured while per-
forming some maintenance pro-
cedures. If you lack sufficient
knowledge and experience or the
proper tools and equipment to do
the work, have it done by an
Authorized Kia Dealer.
 Working under the hood with the engine running is dangerous. It
becomes even more dangerous
when you wear jewelry or loose
clothing. These can become
entangled in moving parts and
result in injury. Always remove all
loose or hanging clothing and all
jewelry before working on the
engine.

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.

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.
