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.
Load-pulling components such as the
engine, transmission, 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:
• State, provincial, county and municipal
government have varying trailering
laws. Make sure your hitch, mirrors,
lights and wiring arrangements are
legal, not only where you live, but also
where you’ll be driving. A good source
for this information is state or local law
enforcement agencies.
• 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.
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
Weight of the trailer tongue
The tongue load of any trailer is an
important weight to measure because it
affects the total gross vehicle weight
(GVW) of your vehicle. This weight
includes the curb weight of the vehicle,
any cargo you may carry in it, and the
people who will be riding in the vehicle.
And if you will tow a trailer, you must add
the tongue load to the GVW because
your vehicle will also be carrying that
weight.
The trailer tongue should weigh a maxi-
mum of 10% of the total loaded trailer
weight. After you've loaded your trailer,
weigh the trailer and then the tongue,
separately, to see if the weights are
proper. If they aren’t, you may be able to
correct them simply by moving some
items around in the trailer.
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:
• Will you have to make any holes in the
body of your vehicle when you install a
trailer hitch? If you do, then be sure to
seal the holes later when you remove
the hitch.
If you don’t seal them, deadly carbon
monoxide (CO) from your exhaust can
get into your vehicle, as well as dirt and
water.
• 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.WARNING - Trailer
• Never load a trailer with more
weight in the rear than in the
front. The front should be loaded
with approximately 60% of the
total trailer load; the rear should
be loaded with approximately
40% of the total trailer load.
• Never exceed the maximum
weight limits of the trailer or trail-
er towing equipment. Improper
loading can result in damage to
your vehicle and/or personal
injury. Check weights and loading
at a commercial scale or highway
patrol office equipped with
scales.
• An improperly loaded trailer can
cause loss of vehicle control.

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 trailer weight without trailer brakes
loaded, then it needs its own brakes and
they must be adequate. Be sure to read
and follow the instructions for the trailer
brakes so you’ll be able to install, adjust
and maintain them properly.
• Don’t tap into your vehicle's brake sys-
tem.
Driving with a trailer
Towing a trailer requires a certain
amount of experience. 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
added weight of 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 mov-
ing and then apply the trailer brake con-
troller by hand to be sure the brakes are
working. This lets you check your electri-
cal 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 work-
ing.
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. This is not a
task for amateurs. Use an experi-
enced, competent trailer shop for
this work.

Driving tips
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 you’re a good deal longer, you’ll
need to go much farther beyond the
passed vehicle before you can return to
your lane.
Backing up
Hold the bottom of the steering wheel
with one hand. Then, to move the trailer
to the left, just 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 possible, 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.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 transmission overheating.
If your trailer weighs more than the max-
imum trailer weight without trailer brakes
and you have an automatic transmission,
you should drive in D (Drive) when tow-
ing a trailer.
Operating your vehicle in D (Drive) when
towing a trailer will minimize heat build up
and extend the life of your transmission.
If you have a manual transmission, drive
in fourth gear (or, as you need to, a lower
gear).
WARNING
Failure to use an approved trailer
wiring harness could result in dam-
age to the vehicle electrical system
and/or personal injury.
CAUTION
• When towing a trailer on steep
grades (in excess of 6%) pay
close attention to the engine
coolant temperature gauge to
ensure the engine does not over-
heat. 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.
• You must decide driving speed
depending on trailer weight and
uphill grade to reduce the possi-
bility of engine and transmission
overheating.

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
transmission fluid, axle lubricant and
cooling system fluid. Brake condition is
another important item to frequently
check. Each item is covered in this man-
ual, 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.CAUTION
• Due to higher load during trailer
usage, overheating might occur
in hot days or during uphill driv-
ing. 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 transmission
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.

EMERGENCY STARTING
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 6-6. 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- 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.
