Driving tips
Weight of the trailer tongueThe 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.

Driving tips34
5Safety 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 tips36
5Do 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%) payclose attention to the enginecoolant temperature gauge to ensure the engine does not over-heat. If the needle of the coolanttemperature gauge moves acrossthe dial towards “H” (HOT), pull over and stop as soon as it is safeto do so, and allow the engine toidle 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 possi- bility of engine and transmissionoverheating.

Maintenance
TIRES AND WHEELS
Tires care For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tire
inflation pressures and stay within
the load limits and weight distribution
recommended for your vehicle.Inflation pressures All tire pressures (including the
spare) should be checked every day
when the tires are cold. “Cold Tires”
means the vehicle has not been driv-
en for at least three hours or driven
less than 1.6 km (one mile).
Recommended pressures must be
maintained for the best ride, top vehi-
cle handling, and minimum tire wear.
(Refer to “Tires” in section 8,
Specifications.) All specifications (sizes and pres-
sures) can be found on a label
attached to the front driver’s door sill.
WARNING
- Tire underin-
flation
Severe underinflation (70 kPa
(10 psi) or more) can lead to
severe heat build-up, causing
blowouts, tread separation and
other tire failures that can result
in the loss of vehicle control
leading to severe injury or
death. This risk is much higher
on hot days and when driving
for protracted periods at high
speeds.

Maintenance
Wheel alignment and tire
balance The wheels on your vehicle were
aligned and balanced carefully at the
factory to give you the longest tire life
and best overall performance.
In most cases, you will not need to
have your wheels aligned again.
However, if you notice unusual tire
wear or your vehicle pulling one way
or the other, the alignment may need
to be reset.
If you notice your vehicle vibrating
when driving on a smooth road, your
wheels may need to be rebalanced.
WARNING -
Replacing
tires
Driving on worn-out tires is very hazardous and will
reduce braking effectiveness,
steering accuracy, and trac-
tion.
Your vehicle is equipped with tires designed to provide for
safe ride and handling capa-
bility. Do not use a size and
type of tire and wheel that is
different from the one that is
originally installed on your
vehicle. It can affect the safety
and performance of your vehi-
cle, which could lead to han-
dling failure or rollover and
serious injury. When replacing
the tires, be sure to equip all
four tires with the tire and
wheel of the same size, type,
tread, brand and load-carrying
capacity.
(Continued)
(Continued)If you nevertheless decide to
equip your vehicle with any
tire/wheel combination not
recommended by Kia for off
road driving, you should not
use these tires for highway
driving.
The use of any other tire size or type may seriously affect
ride, handling, ground clear-
ance, stopping distance, body
to tire clearance, snow tire
clearance, and speedometer
reliability.
It is best to replace all four tires at the same time. If that is
not possible, or necessary,
then replace the two front or
two rear tires as a pair.
Replacing just one tire can
seriously affect your vehicle’s
handling.
CAUTION
Improper wheel weights candamage your vehicle's alu-minum wheels. Use onlyapproved wheel weights.

Cold Tire Pressure: The amount of
air pressure in a tire, measured in
kilopascals (kPa) or pounds per
square inch (psi) before a tire has
built up heat from driving.
Curb Weight: This means the weight
of a motor vehicle with standard and
optional equipment including the
maximum capacity of fuel, oil and
coolant, but without passengers and
cargo.
WARNING

temperature
The temperature grade for this
tire is established for a tire that
is properly inflated and not
overloaded. Excessive speed,
underinflation, or excessive
loading, either separately or in
combination, can cause heat
build-up and possible sudden
tires failure. This can cause loss
of vehicle control and serious
injury or death.
