3Repairing or scrapping the vehicle Repairing/replacing the steering
wheel, instrument panel, center con-
sole headliner/pillar trim, or modifying
vehicle sheet metal components could
disable the air bag system. Have such
repairs and maintenance performed by
an authorized Kia dealer.
 Special care must be taken in scrap-
ping or junking an air bag-equipped
vehicle. Always refer such activities to
a qualified professional.
WARNING
- No mainte-
nance or repair
 Do not work on the air bag sys-
tem’s components or wiring. This
could cause the air bags to inflate
inadvertently, possibly seriously
injuring someone. Working on the
system could also disable the
system so that the air bags would
not deploy in a collision.
 Any work on the air bag system, such as removing, installing, or
repairing the steering wheel must
be performed by a qualified Kia
technician. Improper handling of
the air bag system including the
steering wheel may result in seri-
ous personal injury or death.
Air bag warning labelAir bag warning labels are attached to alert driver and passengers of potential risk of
air bag system.

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.

In case of an emergency66ELECTRICAL CIRCUIT PROTECTIONFuses A vehicle’s electrical system is protected
from electrical overload damage by
fuses.This vehicle has two fuse panels, one
located in the driver's side panel bolster,
the other in the engine compartment
near the battery.
If any of your vehicle’s lights, acces-
sories, or controls do not work, check the
appropriate circuit fuse. If a fuse has
blown, the element inside the fuse will be
melted.
If the electrical system does not work,
first check the driver’s side fuse panel.
Always replace a blown fuse with one of
the same rating.
If the replacement fuse blows, this indi-
cates an electrical problem. Avoid using
the system involved and immediately
consult an authorized Kia dealer.
Two kinds of fuses are used: standard for
lower amperage rating and main for high-er amperage ratings.
Fuse replacement ✽ ✽ NOTICEDo not use a screwdriver or any other
metal object to remove fuses because it
may cause a short circuit and damage
the system.
WARNING
- Fuse replace-
ment
 Never replace a fuse with any-
thing but another fuse of the
same rating.
 A higher capacity fuse could cause damage through overheat-
ing and possibly a fire.
 Never install a wire instead of the proper fuse - even as a temporary
repair. It may cause extensive
wiring damage and possibly a
fire.
