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.

OFF/LO/HI/MIST: See the explanation
for type A operation.
AUTO (if equipped)
; The rain sensor located on the upperend of windshield glass senses the
amount of rainfall and controls the wip-
ing cycle for the proper intervals. The
more it rains, the faster the wiper oper-
ates. When the rain stops, the wiper
stops. To vary the speed setting, turn
the speed control knob (1). (S : slow
operation, F: fast operation.) If the ignition switch is turned ON when
the wiper switch is set in AUTO mode, or
wiper switch is set in AUTO mode when
the ignition switch is ON, wiper will oper-
ate once to perform a self-check of the
system. Set the wiper to OFF position
when the wiper is not in use.
✽ ✽
NOTICEWhen washing the vehicle, set the wiper
switch in the OFF position to stop the
auto wiper operation.
Wiper may operate and be damaged if
the switch is set in AUTO mode while

Driving tips
 Carbon monoxide can be present withother exhaust fumes. Therefore, if you
smell exhaust fumes of any kind inside
your vehicle, have it inspected and
repaired immediately. If you ever sus-
pect exhaust fumes are coming into
your vehicle, drive it only with all the
windows fully open. Have your vehicle
checked and repaired immediately.
 Do not operate the engine in confined or closed areas (such as garages) any
more than what is necessary to move
the vehicle in or out of the area.
 When the vehicle is stopped in an open area for more than a short time
with the engine running, adjust the
ventilation system (as needed) to draw
outside air into the vehicle.
 Never sit in a parked or stopped vehi- cle for any extended time with the
engine running.
 When the engine stalls or fails to start, excessive attempts to re-start the
engine may cause damage to the
emission control system.
Operating precautions for catalytic
converters Your vehicle is equipped with a catalytic
converter emission control device.
Therefore, the following precautions
must be observed:
 Use only UNLEADED FUEL for gaso-line engine (unleaded).
 Do not operate the vehicle when there are signs of engine malfunction, such
as misfire or a noticeable loss of per-
formance.
 Do not misuse or abuse the engine. Examples of misuse are coasting with
the ignition off and descending steep
grades in gear with the ignition off.  Do not operate the engine at high idle
speed for extended periods (5 minutes
or more).
 Do not modify or tamper with any part of the engine or emission control sys-
tem. All inspections and adjustments
must be made by an authorized Kia
dealer.
Failure to observe these precautions
could result in damage to the catalytic
converter and to your vehicle.
Additionally, such actions could void your
warranties.
WARNING
- Fire
A hot exhaust system can ignite
flammable items under your vehi-
cle. Do not park the vehicle over or
near flammable objects, such as
grass, vegetation, paper, leaves,
etc.

Driving tips
Driving at night Because night driving presents more
hazards than driving in the daylight, here
are some important tips to remember:
 Slow down and keep more distancebetween you and other vehicles, as it
may be more difficult to see at night,
especially in areas where there may
not be any street lights.
 Adjust your mirrors to reduce the glare from other driver's headlights.
 Keep your headlights clean and prop- erly aimed on vehicles not equipped
with the automatic headlight aiming
feature. Dirty or improperly aimed
headlights will make it much more diffi-
cult to see at night.
 Avoid staring directly at the headlights of oncoming vehicles. You could be
temporarily blinded, and it will take
several seconds for your eyes to read-
just to the darkness.
Driving in the rain Rain and wet roads can make driving
dangerous, especially if you’re not pre-
pared for the slick pavement. Here are a
few things to consider when driving in the
rain:
 A heavy rainfall will make it harder tosee and will increase the distance
needed to stop your vehicle, so slow
down.
 Keep your windshield wiping equip- ment in good shape. Replace your
windshield wiper blades when they
show signs of streaking or missing
areas on the windshield.
 If your tires are not in good condition, making a quick stop on wet pavement
can cause a skid and possibly lead to
an accident. Be sure your tires are in
good shape.
 Turn on your headlights to make it eas- ier for others to see you.
 Driving too fast through large puddles can affect your brakes. If you must go
through puddles, try to drive through
them slowly.
 If you believe you may have gotten your brakes wet, apply them lightly
while driving until normal braking oper-
ation returns.
Winter driving We recommend that you carry emer-gency equipment, including a window
scraper, windshield de-icer, a bag of
sand or salt, flares, a small shovel and
jumper cables.
 Make sure you have sufficient ethyl- ene-glycol coolant in the radiator.
 Check the battery condition and cables. Cold temperatures reduce the
output capability of any battery, so it
must be in excellent condition to pro-
vide enough winter starting power.
 Make sure the engine oil viscosity is suitable for cold weather.
 Check the ignition system for loose connections and damage.
 Use antifreeze-formulated windshield washer fluid. (Do not use engine
coolant antifreeze.)
 Do not use the parking brake if it might freeze. When parking, shift to 1 (First)
or R (Reverse) with a manual transaxle
or P (Park) with an automatic transaxle
and block the rear wheels.

Driving tips
Driving with a trailer Towing a trailer requires experience. You
must gain that experience slowly and
carefully which practicing with an
unloaded or lightly loaded trailer. Before
setting out for the open road, you must
get to know your trailer. Acquaint yourself
with the feel of handling and braking with
the trailer. And always keep in mind that
the vehicle you are driving is now a good
deal longer and not nearly so responsive
as your vehicle is by itself.
Before you start, check the trailer hitch
and platform, safety chains, electrical
connector(s), lights, tires and mirror
adjustment. If the trailer has brakes, fol-
low the trailer manufacturer’s instructions
as to how to check the brakes before you
start driving.
During your trip, stop every hour or so to
be sure that the load is secure, and that
the lights and any trailer brakes are work-
ing.Following distance Stay at least twice as far behind the vehi-
cle ahead as you would when driving
your vehicle without a trailer. This can
help you avoid situations that require
heavy braking and sudden turns.
Passing You’ll need more passing distance up
ahead when you’re towing a trailer. And,
because of the increased vehicle length,
you’ll need to go much farther beyond the
passed vehicle before you can return to
your lane.Backing up The trailer will go in the opposite direc-
tion of the rear of your vehicle when
backing up. This is very difficult for an
inexperienced trailer driver to get used
to. To help you avoid mistakes, hold the
bottom of the steering wheel with one
hand. Then, to move the trailer to the left,
just hold the steering wheel firmly and
move your hand to the left. To move the
trailer to the right, move your hand to the
right. Always back up slowly and, if pos-
sible, have someone guide you.Making turns When you’re turning with a trailer, make
wider turns than normal. Do this so your
trailer won’t strike soft shoulders, curbs,
road signs, trees, or other objects. Avoid
jerky or sudden maneuvers. Signal well
in advance.
Turn signals when towing a trailer When you tow a trailer, your vehicle has
to have a different turn signal flasher and
extra wiring. The green arrows on your
instrument panel will flash whenever you
signal a turn or lane change. Properly
connected, the trailer lights will also flash
to alert other drivers you’re about to turn,
change lanes, or stop.
When towing a trailer, the green arrows
on your instrument panel will flash for
turns even if the bulbs on the trailer are
burned out. Thus, you may think drivers
behind you are seeing your signals
when, in fact, they are not. It’s important
to check occasionally to be sure the trail-
er bulbs are still working. You must also
check the lights every time you discon-
nect and then reconnect the wires.
Do not connect a trailer lighting system
directly to your vehicle’s lighting system.
Use only an approved trailer wiring har-
ness.
Your Authorized Kia Dealer can assist
you in installing the wiring harness.
WARNING -

Failure to use an approved trailer
wiring harness could result in an
accident due to the failure of the
trailer lights to operate.

✽
NOTICEFailure to sue a trailer wiring harness
can damage your vehicle’s electrical sys-
tem.Driving on grades Reduce speed and shift to a lower gear
before you start down a long or steep
downgrade. If you don’t shift down, you
might have to use your brakes so much
that they would get hot and no longer
operate efficiently.
On a long uphill grade, shift down and
reduce your speed to around 70 km/h (45
mph) to reduce the possibility of engine
and transaxle overheating.
Operating your vehicle in D (Drive) when
towing a trailer will minimize heat build up
and extend the life of your transaxle.
Parking on hills Generally, you should not park your vehi-
cle, with a trailer attached, on a hill.
People can be seriously or fatally injured,
and both your vehicle and the trailer can
be damaged if they begin a downhill.
However, if you ever have to park your
trailer on a hill, here’s how to do it: 1. Apply your brakes, but don’t shift into
gear.
2. Have someone place chocks (blocks of wood or metal intended for this pur-
pose) under the downhill sides of the
trailer wheels.
3. When the wheel chocks are in place, release the brakes until the chocks
absorb the load.
4. Reapply the brakes. Apply your park- ing brake, and then shift to P (Park) for
an automatic transaxle.
5. Release the brakes.
CAUTION
When towing a trailer on steep grades (in excess of 6%) pay closeattention to the engine coolant tem-perature gauge to ensure theengine does not overheat. If theneedle of the coolant temperaturegauge moves across the dialtowards “H” (HOT), pull over andstop as soon as it is safe to do so,and allow the engine to idle until itcools down. You may proceed oncethe engine has cooled sufficiently.
WARNING
- Parking on a
hill
Parking your vehicle on a hill with a
trailer attached is dangerous. It
could cause serious injury or death,
should the trailer break lose, or
should the trailer drag the vehicle
downhill.
WARNING
- Parking brake
It can be dangerous to get out of
your vehicle if the parking brake is
not firmly set or if the engine is still
running.
In either case the vehicle can move
suddenly. You or others could be
seriously or fatally injured.

Driving tips
When you are ready to leave afterparking on a hill 1. With the automatic transaxle in P (Park), apply your brakes and hold the
brake pedal down while you:
 Start your engine;
 Shift into gear; and
 Release the parking brake.
2. Slowly remove your foot from the brake pedal.
3. Drive slowly forward until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.Maintenance when trailer towing Your vehicle will need service more often
when you regularly pull a trailer.
Important items to pay particular atten-
tion to include engine oil, automatic
transaxle fluid, axle lubricant and cooling
system fluid. Brake condition is another
important item to frequently check. Each
item is covered in this manual, and the
Index will help you find them quickly. If
you’re trailering, it’s a good idea to review
these sections before you start your trip. Don’t forget to also maintain your trailer
and hitch. Follow the maintenance
schedule that accompanied your trailer
and check it periodically. Preferably, con-
duct the check at the start of each day’s
driving. Most importantly, all hitch nuts
and bolts should be tight.
✽ ✽
NOTICE• Due to higher load during trailer
usage, overheating might occur in hot
days or during uphill driving. If the
coolant gauge indicates over-heating,
switch off the A/C and stop the vehicle
in a safe area to cool down the engine.
• When towing check transaxle fluid more frequently.
• If your vehicle is not equipped with the air conditioner, you should install
a condenser fan to improve engine
performance when towing a trailer.
If you do decide to pull a trailerHere are some important points if you
decide to pull a trailer:
 Consider using a sway control. You can
ask a hitch dealer about sway control.
 After your odometer indicates 800 km (500 miles) or more, you can tow a
trailer. For the first 800 km (500 miles)
that you tow a trailer, don’t drive over
80 km/h (50 mph) and don’t make
starts at full throttle. This helps your
engine and other parts of your vehicle
“wear” in at the heavier loads.
 Always drive your vehicle at a moder- ate speed (less than 100 km/h (60
mph)).
 On a long uphill grade, do not exceed 70 km/h (45 mph) or the posted towing
speed limit, whichever is lower.
 The important considerations have to do with weight:
Weight of the trailer
How heavy can a trailer safely be? It
should never weigh more than the maxi-
mum trailer weight with trailer brakes. But
even that can be too heavy. If you feel that
the trailer is adversely affecting the move-
ment of your vehicle, reduce your speed,
avoid uneven or winding roads, avoid
roads with steep grades, and/or lighten
your trailer load.
