Calculating the load your vehicle
can tow
1. Use the appropriate maximumGCWR chart (in the Weight of the
Trailer section in this chapter) for
your type of drive system and
transmission.
2. Weigh your vehicle.
3. Subtract the weight of your vehicle from the maximum GCWR in the
chart. This is the maximum trailer
weight your vehicle can tow. It
must be below the maximum trail-
er weight shown in the chart. Note
that the maximum trailer weight
your vehicle can tow depends on
the total weight of any cargo, pas-
sengers and available equipment
in the vehicle. To identify what the vehicle trailering
capacity is for your vehicle, you
should read the information in
“Weight of the Trailer” that appears
later in this section. Remember that
trailering is different than just driving
your vehicle by itself. Trailering caus-
es major changes in handling, dura-
bility, and fuel economy. Successful,
safe trailering requires correct equip-
ment, and cautious driving.
WARNING
- Towing a
trailer
If you don't use the correct
equipment or you drive improp-
erly, you can lose control when
you pull a trailer. For example, if
the trailer is too heavy, the
brakes may fail, and would at
least be ineffective to promptly
stop the vehicle. You and your
passenger could be seriously or
fatally injured. We do not recom-
mend towing a trailer. However,
in the event there is a need to
tow a trailer, such as in an emer-
gency, follow all the steps in this
section.
Item Specification
Maximum trailer Without trailer brakes 340 (750)
weight kg (lbs.) With trailer brakes 680 (1500)

This section contains many time-
tested, important trailering tips and
safety rules. Many of these are
important for your safety and that of
your passengers. Please read this
section carefully before you pull a
trailer.
Load-pulling components such as
the engine, transaxle, wheel assem-
blies, 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 addi-
tional burden generates extra heat
which creates more wear in engine,
and a shortened engine life. The trail-
er also adds considerably to wind
resistance, increasing the pulling
requirements.
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 throt-
tle. This helps your engine and
other parts of your vehicle “wear” in
at the heavier loads.
 Always drive your vehicle at a mod- erate speed (less than 100 km/h
(60 mph)).
 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
maximum trailer weight with trailer
brakes. But even that can be too
heavy.
If you feel that the trailer is adversely
affecting the movement of your vehi-
cle, reduce your speed, avoid
uneven or winding roads, avoid
roads with steep grades, and/or light-
en your trailer load.

Safety chains You should always attach chains
between your vehicle and your trail-
er. Cross the safety chains under the
tongue of the trailer so that the
tongue will not drop to the road if it
becomes separated from the hitch.
Instructions about safety chains may
be provided by the hitch manufactur-
er or by the trailer manufacturer.
Follow the manufacturer’s recom-
mendation for attaching safety
chains. Always leave just enough
slack so you can turn with your trail-
er. And, never allow safety chains to
drag on the ground.
Trailer brakes If your trailer weighs more than the
maximum weight for a trailer without
brakes, then the trailer needs its own
brakes. You must consult with a
knowledgeable and reputable trailer
vendor to determine which brake
equipped trailer is right for your
needs. Be sure to read and follow the
instructions for the trailer brakes so
you’ll be able to install, adjust and
maintain them properly.
Driving with a trailer Towing a trailer requires experience.
You must gain that experience slow-
ly 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 electric brakes, start your vehicle
and trailer moving and then apply the
trailer brake controller by hand to be
sure the brakes are working. This lets
you check your electrical connection
at the same time.
During your trip, check occasionally
to be sure that the load is secure,
and that the lights and any trailer
brakes are still working.
WARNING
Do not use a trailer with its own
brakes unless you are absolute-
ly certain that you have properly
set up the brake system. This is
not a task for amateurs. Use an
experienced, competent trailer
shop for this work.

Do not connect a trailer lighting sys-
tem directly to your vehicle’s lighting
system. Use only an approved trailer
wiring harness.
Your Authorized Kia Dealer can
assist you in installing the wiring har-
ness.
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 possi-
bility of engine and transaxle over-
heating.
Operating your vehicle in D (Drive)
when towing a trailer will minimize
heat buildup and extend the life of
your transaxle.
WARNING
- Trailer wiring
harness
Failure to use an approved trail-
er wiring harness could result in
damage to the vehicle's electri-
cal system, there by disabling
the brake light system resulting
in an accident.
CAUTION
When towing a trailer on steep grades especially (in excess of6%) pay close attention to theengine coolant temperaturegauge to ensure the enginedoes not overheat. If the needleof the coolant temperaturegauge moves across the dialtowards “H” (HOT), pull over andstop as soon as it is safe to doso, and allow the engine to idleuntil it cools down. You may pro-ceed once the engine hascooled sufficiently.

Parking on hills Generally, you should not park your
vehicle, with a trailer attached, on a
hill. People can be seriously or fatal-
ly injured, and both your vehicle and
the trailer can be damaged if they
begin to move 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 purpose) under the down-
hill 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 parking brake, and then shift to R
(Reverse) for a manual transaxle
or P (Park) for an automatic
transaxle.
5. Release the brakes.
When you are ready to leave after parking on a hill 1. With the manual transaxle in Neutral or 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 trail- er is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
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 serious-
ly or fatally injured.
WARNING
- Parking on a hill
Parking your vehicle on a hill
with a trailer attached is danger-
ous. It could cause serious
injury or death, should the trail-
er break lose, or should the trail-
er drag the vehicle downhill.

Maintenance when trailer tow-
ing Your vehicle will need service more
often when you regularly pull a trail-
er. Important items to pay particular
attention to include engine oil, auto-
matic transaxle fluid, axle lubricant
and cooling system fluid. Brake con-
dition is another important item to
frequently check. Each item is cov-
ered 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 mainte-
nance schedule that accompanied
your trailer and check it periodically.
Preferably, conduct the check at the
start of each day’s driving. Most
importantly, all hitch nuts and bolts
should be tight.
CAUTION
 Due to higher load during
trailer usage, overheatingmight occur in hot days orduring uphill driving. If thecoolant gauge indicates over-heating, switch off the A/C andstop the vehicle in a safe areato cool down the engine.
 When towing check transaxle fluid more frequently.
 If your vehicle is not equipped with the air conditioner, youshould install a condenser fanfor engine performance whentowing a trailer.

OVERHEATING If your temperature gauge indicates
overheating, if you experience a loss
of power, or if you hear a loud knock-
ing or pinging noise, the engine has
probably overheated. Should any of
these symptoms occur, use the fol-
lowing procedure:
1. Turn on the hazard warning flash-er, then drive to the nearest safe
location and stop your vehicle; set
the automatic transaxle in P
(Park), or shift the manual
transaxle to N (Neutral) 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.
4. The coolant level should then be checked. If the level in the reser-
voir 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 another prob-
lem that may have caused the
engine to overheat, do not operate
the engine until it has been cor-
rected. Call an Authorized Kia
Dealer for assistance. If you do not
find a leak or other problem, care-
fully add coolant to the reservoir.
If the engine frequently overheats,have the cooling system checkedand repaired by an Authorized KiaDealer.
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 seri-
ous injury.
