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 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 -
Trailer wiring
harness
Failure to use an approved trailer
wiring harness could result in an
accident due to the failure of the
trailer lights to operate.

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.

Driving tips14 5Weight 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 since that is the
trailer weight pushing down on the hitch
on your vehicle. The rest of the trailer
weight is sitting on the trailer’s wheels.
The trailer tongue should weigh a maxi-
mum of 10% of the total loaded trailer
weight. After you've loaded the trailer, go
to a Weigh Station and 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.
WARNING -
Trailer balance
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 excessive
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.
WARNING
- Vehicle weight
The gross axle weight rating
(GAWR) and the gross vehicle
weight rating (GVWR) for your vehi-
cle are on the manufacturer's label
attached to the driver's door.
Exceeding these ratings can cause
an accident or vehicle damage. You
can calculate the weight of your
load by weighing the items (and
people) before putting them in the
vehicle. Be careful not to overload
your vehicle.
