TRAILER TOWING
✽ ✽
NOTICE
Pulling a trailer improperly can damage
your vehicle and result in costly repairs
not covered by your warranty. To identify what the vehicle trailering
capacity is for your vehicle, you should
refer to the chart on this page.Remember that trailering is different than
just driving your vehicle by itself.
Trailering causes major changes in han-
dling, durability, and fuel economy.
Successful, safe trailering requires cor-
rect equipment, and cautious driving.
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.
WARNING
- Towing a trail-
er
If you don't use the correct equip-
ment or you drive improperly, 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 passengers could be seriously
or fatally injured. Pull a trailer only if
you have followed all the steps in
this section.
WARNING
- Weight limits
Before towing, make sure the total
trailer weight, gross combination
weight, gross vehicle weight, gross
axle weight and trailer tongue load
are all within the limits.

Driving tips10 5Load-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
which creates more wear in engine, and
a shortened engine life. The trailer also
adds considerably to wind resistance,
increasing the pulling requirements.Hitches It's important to have the correct hitch
equipment. Crosswinds, large trucks
going by, and rough roads are a few rea-
sons why you’ll need the right hitch. Here
are some rules to follow:
Do not attach a trailer hitch which
requires you to alter other parts on
your vehicle.
Never make a hole in your vehicle to
accommodate a hitch.
The bumpers on your vehicle are not
intended for hitches. Do not attach
rental hitches or other bumper-type
hitches to them. Use only a frame-
mounted hitch that does not attach to
the bumper.
Safety chains You should always attach chains
between your vehicle and your trailer.
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 manufacturer or by
the trailer manufacturer. Follow the man-
ufacturer’s recommendation for attaching
safety chains. Always leave just enough
slack so you can turn with your trailer.
And, never allow safety chains to drag on
the ground.
Trailer brakes If your trailer weighs more than the max-
imum weight for a trailer without brakes,
then the trailer needs its own brakes. You
must consult with a knowledgeable and
reputabel 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 main-
tain them properly.
WARNING
If you damage the body of your car,
installing, or using a trailer hitch,
you must have any resulting hole
immediately repaired, An unsealed
hole can allow deadly carbon
monoxide (CO) from your exhaust
into your vehicle.
WARNING
- Trailer brakes
Do not use a trailer with its own
brakes unless you are absolutely
certain that you have properly set
up the brake system pursuant to
the trailer manufacture’s instruc-
tions. This is not a task for ama-
teurs. Use an experienced, compe-
tent trailer shop for this work.
WARNING
- Trailer and
vehicle brakes
NEVER connect or allow anyone
else to connect your vehicle’s
brakes to any trailer brake system.
Altering your vehicle’s brakes could
result in total brake failure.

Driving tips12 5✽
✽
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 close
attention to the engine coolant tem-
perature gauge to ensure the
engine does not overheat. If the
needle of the coolant temperature
gauge moves across the dial
towards “H” (HOT), pull over and
stop as soon as it is safe to do so,
and allow the engine to idle until it
cools down. You may proceed once
the 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 after
parking on a hill 1. With the automatic transaxle in P
(Park), apply your brakes and hold the
brake pedal down while you:

and

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.

In case of an emergency2 6ROAD 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), 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 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, have
the 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. If in doubt, we strongly recom-
mend that you have a competent techni-
cian or towing service jump start your
vehicle.✽ ✽
NOTICEUse 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.

In case of an emergency4 6Connecting 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. Remove the engine cover.
5. 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 (
1), then con-
nect the other end to the positive ter-
minal on the booster battery (
2).
6. Proceed to connect one end of the
other jumper cable to the negative ter-
minal of the booster battery (
3), then
the other end to a solid, stationary,
metallic point (for example, the engine
lifting bracket) away from the battery
(
