Driving tips
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.

In case of an emergency66ELECTRICAL CIRCUIT PROTECTIONFuses A vehicle’s electrical system is protected
from electrical overload damage by
fuses.This vehicle has two fuse panels, one
located in the driver's side panel bolster,
the other in the engine compartment
near the battery.
If any of your vehicle’s lights, acces-
sories, or controls do not work, check the
appropriate circuit fuse. If a fuse has
blown, the element inside the fuse will be
melted.
If the electrical system does not work,
first check the driver’s side fuse panel.
Always replace a blown fuse with one of
the same rating.
If the replacement fuse blows, this indi-
cates an electrical problem. Avoid using
the system involved and immediately
consult an authorized Kia dealer.
Two kinds of fuses are used: standard for
lower amperage rating and main for high-er amperage ratings.
Fuse replacement ✽ ✽ NOTICEDo not use a screwdriver or any other
metal object to remove fuses because it
may cause a short circuit and damage
the system.
WARNING
- Fuse replace-
ment
 Never replace a fuse with any-
thing but another fuse of the
same rating.
 A higher capacity fuse could cause damage through overheat-
ing and possibly a fire.
 Never install a wire instead of the proper fuse - even as a temporary
repair. It may cause extensive
wiring damage and possibly a
fire.

In case of an emergency
The compact spare should be inflat-
ed to 420 kPa (60 psi).✽ ✽NOTICECheck the inflation pressure after
installing the spare tire. Adjust it to
the specified pressure, as necessary.
When using a compact spare tire,
observe the following precautions:
 Under no circumstances should
you exceed 80 km/h (50 mph); a
higher speed could damage the
tire.
 Ensure that you drive slowly enough for the road conditions to
avoid all hazards. Any road hazard,
such as a pothole or debris, could
seriously damage the compact
spare.
 Any continuous road use of this tire could result in tire failure, loss of
vehicle control, and possible per-
sonal injury.
 Do not exceed the vehicle’s maxi- mum load rating or the load-carry-
ing capacity shown on the sidewall
of the compact spare tire.
 Avoid driving over obstacles. The compact spare tire diameter is
smaller than the diameter of a con-
ventional tire and reduces the
ground clearance approximately
25 mm (1 inch), which could result
in damage to the vehicle.  Do not take the vehicle through an
automatic car wash with a compact
spare.
 Do not use tire chains on this tire. Because of the smaller size, a tire
chain will not fit properly. This could
damage the vehicle and result in
loss of the chain.
 This tire should not be installed on the front axle if the vehicle must be
driven in snow or on ice.
 Do not use the compact spare tire on any other vehicle because this
tire has been designed especially
for your vehicle.
 The compact spare tire’s tread life is shorter than a regular tire.
Inspect your compact spare tire
regularly and replace worn com-
pact spare tires with the same size
and design, mounted on the same
wheel.
CAUTION
- Compact
spare
This spare tire should be usedonly for VERY short distances.Compact spares should NEVERbe used for long drives orextended distances.

Wheel replacement When replacing the metal wheels for
any reason, make sure the new
wheels are equivalent to the original
factory units in diameter, rim width
and offset.
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.
WARNING
A wheel that is not the correct
size may adversely affect wheel
and bearing life, braking and
stopping abilities, handling char-
acteristics, ground clearance,
body-to-tire clearance, snow
chain clearance, speedometer
calibration, headlight aim and
bumper height.

All season tires Kia specifies all season tires on
some models to provide good per-
formance for use all year round,
including snowy and icy road condi-
tions. All season tires are identified
by ALL SEASON and/or M+S (Mud
and Snow) on the tire sidewall. Snow
tires have better snow traction than
all season tires and may be more
appropriate in some areas.
Summer tires Kia specifies summer tires on some
models to provide superior perform-
ance on dry roads. Summer tire per-
formance is substantially reduced in
snow and ice. Summer tires do not
have the tire traction rating M+S
(Mud and Snow) on the tire side wall.
if you plan to operate your vehicle in
snowy or icy conditions. Kia recom-
mends the use of snow tires or all
season tires on all four wheels.Snow tiresIf you equip your car with snow tires,
they should be the same size and
have the same load capacity as the
original tires. Snow tires should be
installed on all four wheels; other-
wise, poor handling may result.
Snow tires should carry 28 kPa
(4 psi) more air pressure than the
pressure recommended for the stan-
dard tires on the tire label on the dri-
ver's side of the center pillar, or up to
the maximum pressure shown on the
tire sidewall, whichever is less.
Do not drive faster than 120 km/h (75
mph) when your car is equipped with
snow tires.
