Driving tips
Load-pulling components such as the
engine, transaxle, wheel assemblies, and
tires are forced to work harder against
the load of the added weight. The engine
is required to operate at relatively higher
speeds and under greater loads. This
additional burden generates extra heat.
The trailer also adds considerably to
wind resistance, increasing the pulling
requirements.If you do decide to pull a trailer
Here are some important points if you
decide to pull a trailer:
• Consider using a sway control. You canask 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 at a safe speed (less than 100 km/h) commensurate with road
conditions.
• 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 908 kg
(2000 lbs.) with trailer brakes. But even
that can be too heavy.
It depends on how you plan to use your
trailer. For example, speed, altitude, road
grades, outside temperature and how
much your vehicle is used to pull a trailer
are all important. The ideal trailer weight
can also depend on any special equip-
ment that you have on your vehicle.

Driving tips
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.
If your trailer weighs more than 454 kg
(1000 lbs.) and you have an automatic
transaxle, you should drive in D (Drive)
when towing a trailer.
Operating your vehicle in D (Drive) when
towing a trailer will minimize heat buildup
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 tra-
jectory.CAUTION
• When towing a trailer on steep
grades (in excess of 6%) pay
clo se attention to the engine
coolant temperature gauge to ensure the engine does not over-heat. If the needle of the coolanttemperature gauge moves across the dial towards “H” (HOT), pullover and stop as soon as it is safe
to do so, and allow the engine to idle until it cools down. You mayproceed once the engine has cooled sufficiently.
• You must decide driving speed depending on trailer weight anduphill grade to reduce the po ssi-
bility of engine and trans axle
overheating.
WARNING- Parking on a hill
Parking your vehicle on a hill with a
trailer attached could cause serious
injury or death, should a down hill
trajectory happen.

Driving tips

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 intogear.
2. Have someone place chocks under 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.When you are ready to leave after parking 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 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 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.
WARNING- Parking brake
It can be dangerous to get out of
your vehicle if the parking brake i s
not firmly set.
If you have left the engine running,
the vehicle can move suddenly. You
or other s could be s eriously or
fatally injured.
CAUTION
Due to higher load during trailer usage, overheating might occur inhot days or during uphill driving. Ifthe coolant gauge indicate s over-
heating, switch off the A/C and stop
the vehicle in a safe area to cool
down the engine.

ROAD WARNING
Hazard warning flasher
The hazard warning flasher serves as a
warning to other drivers to exercise
extreme caution when approaching,
overtaking, or passing your vehicle. It
should be used whenever emergency
repairs are being made or when the vehi-
cle is stopped near the edge of a road-
way.Depress the flasher switch with the igni-
tion switch in any position. The flasher
switch is located in the center console
switch panel. All turn signal lights will
flash simultaneously.
• The hazard warning flasher operates
whether your vehicle is running or not.
• The turn signals do not work when the hazard flasher is on.
• Care must be taken when using the hazard warning flasher while the vehi-
cle is being towed. If your temperature gauge indicates over-
heating, if you experience a loss of
power, or if you hear a loud knocking or
pinging noise, the engine has probably
overheated. Should any of these symp-
toms occur, use the following procedure:
1. Turn on the hazard warning flasher,
then drive to the nearest safe location
and stop your vehicle; set the automat-
ic transaxle in P (Park) and apply the
parking brake.
2. Make sure the air conditioner is off.
3. If coolant or steam is boiling out of the radiator, stop the engine and call an
Authorized Kia Dealer for assistance.
If coolant is not boiling out, allow the
engine to idle and open the hood to
permit the engine to cool gradually.
If the temperature does not go down
with the engine idling, stop the engine
and allow sufficient time for it to cool.

In case of an emergency
4. The coolant level should then bechecked. If the level in the reservoir is
low, look for leaks at the radiator hoses
and connections, heater hoses and
connections, radiator, and water
pump. If you find a major leak or anoth-
er problem that may have caused the
engine to overheat, do not operate the
engine until it has been corrected. Call
an Authorized Kia Dealer for assis-
tance. If you do not find a leak or other
problem, carefully add coolant to the
reservoir.
If the engine frequently overheats, havethe cooling system checked and repaired by an Authorized Kia Dealer.
Jump starting
Jump starting can be dangerous if done
incorrectly. Therefore, to avoid harm to
yourself or damage to your vehicle or
battery, follow the jump starting proce-
dures listed on page 6-4. If in doubt, we
strongly recommend that you have a
competent technician or towing service
jump start your vehicle.
✽
NOTICE
Use only a 12-volt jumper system. You
can damage a 12-volt starting motor,
ignition system, and other electrical
parts beyond repair by use of a 24-volt
power supply (either two 12-volt batter-
ies in series or a 24-volt motor generator
set).
WARNING- Removing
radiator cap
Do not remove the radiator cap
when the engine and radiator are
hot. Scalding hot coolant and steam
may blow out under pressure. This
could cause serious injury.
EMERGENCY STARTING
WARNING- Battery
• Keep all flames or sparks away
from the battery. The battery pro-
duces hydrogen gas which may
explode if exposed to flame or
sparks.
• Do not attempt to jump start the
vehicle if the discharged battery
is frozen or if the electrolyte level
is low; the battery may rupture or
explode.
WARNING- Battery
Never attempt to check the elec-
trolyte level of the battery as this
may cause the battery to rupture or
explode causing serious injury.

Connecting jumper cables Jump starting procedure
1. Make sure the booster battery is 12-
volt and that its negative terminal is
grounded.
2. If the booster battery is in another vehicle, do not allow the vehicles to
touch.
3. Turn off all unnecessary electrical loads.
4. Connect the jumper cables in the exact sequence shown in the previous illus-
tration. First connect one end of a
jumper cable to the positive terminal of
the discharged battery (
➀), then con-
nect the other end to the positive ter-
minal on the booster battery (
➁).
Proceed to connect one end of the
other jumper cable to the negative ter-
minal of the booster battery (
➂), then
the other end to a solid, stationary,
metallic point (for example, the engine
lifting bracket) away from the battery
(
➃). Do not connect it to or near any
part that moves when the engine is
cranked. Do not connect the jumper
cable from the negative terminal of the
booster battery to the negative termi-
nal of the discharged battery.

WARNING - Fuse replace-ment
• Never replace a fuse with any-
thing but another fus e of the
same rating.
• A higher capacity fus e could
caus e damage and possibly a
fire.
• Never install a wire instead of the proper fuse - even as a temporary
repair. It may caus e extensive
wiring damage and possibly a
fire.
• Do not use a screwdriver or any other metal object to remove
fuses because it may cause a
short circuit and damage the sys-
tem.
This vehicle has two fuse panels, one
located in the driver's side knee 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.Fuse replacement
1. Turn the ignition switch and all other switches off.
2. Pull the suspected fuse straight out. Use the removal tool provided on the
main fuse box in the engine compart-
ment.
3. Check the removed fuse; replace it if it is blown.
Spare fuses are provided in the fusepanel.
4. Push in a new fuse of the same rating, and make sure it fits tightly in the clips.
If it fits loosely, consult an Authorized Kia
Dealer.

In case of an emergency
If you do not have a spare, use a fuse ofthe same rating from a circuit you maynot need for operating the vehicle, suchas the radio or room lamp fuse.
If the headlights or other electrical com-
ponents do not work and the fuses are
OK, check the fuse block in the engine
compartment. If a fuse is blown, it must
be replaced. To check the fuse or relay in the engine
compartment, remove the engine com-
partment shroud.
1. Turn the ignition switch and all other
switches off.
2. Remove the fuse box cover by remov- ing the bolt on the cover and unhook-
ing the tab on one end and tilting the
cover back toward the other end.
3. Check the fuses. If one is blown, replace it with a new one of the same
rating.
✽NOTICE
After checking the fuse box in the engine
compartment, securely install the fuse
box cover. If not, electrical failures may
occur from water leaking in.
