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 -

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

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 used
only for VERY short distances.
Compact spares should NEVER
be used for long drives or
extended distances.

Maintenance2 7MAINTENANCE SERVICESYou should exercise the utmost care to
prevent damage to your vehicle and
injury to yourself whenever performing
any maintenance or inspection proce-
dures.
Should you have any doubts concerning
the inspection or servicing of your vehi-
cle, we strongly recommend that you
have an authorized Kia dealer perform
this work.
An authorized Kia dealer has factory-
trained technicians and genuine Kia
parts to service your vehicle properly. For
expert advice and quality service, see an
authorized Kia dealer.
Inadequate, incomplete or insufficient
servicing may result in operational prob-
lems with your vehicle that could lead to
vehicle damage, an accident, or person-
al injury.
Owner’s responsibility Maintenance Service and Record
Retention are the owner's responsibil-
ity.
You should retain documents that show
proper maintenance has been performed
on your vehicle in accordance with the
scheduled maintenance service charts
shown on the following pages. You need
this information to establish your compli-
ance with the servicing and maintenance
requirements of your Kia warranties.
Detailed warranty information is provided
in your Warranty & Consumer Information
manual.
Repairs and adjustments required as a
result of improper maintenance or a lack
of required maintenance are not covered.
We strongly recommend that all vehicle
maintenance be performed by an author-
ized Kia dealer using genuine Kia parts.

The chart below lists many of the dif-
ferent speed ratings currently being
used for passenger cars. The speed
rating is part of the tire size designa-
tion on the sidewall of the tire. This
symbol corresponds to that tire's
designed maximum safe operating
speed.
3. Checking tire life (TIN : Tire
Identification Number) Any tires that are over 6 years, based
on the manufacturing date, tire
strength and performance, decline
with age naturally (even unused
spare tires). Therefore, the tires
(including the spare tire) should be
replaced by new ones. You can find
the manufacturing date on the tire
sidewall (possibly on the inside of the
wheel), displaying the DOT Code.
The DOT Code is a series of num-
bers on a tire consisting of numbers
and English letters. The manufactur-
ing date is designated by the last four
digits (characters) of the DOT code.
DOT : XXXX XXXX OOOO
The front part of the DOT means a
plant code number, tire size and
tread pattern and the last four num-
bers indicate week and year manu-
factured.
For example:
DOT XXXX XXXX 1605 represents
that the tire was produced in the 16th
week of 2005.
S 180 km/h (112 mph)
T 190 km/h (118 mph)
H 210 km/h (130 mph)
V 240 km/h (149 mph)
Z Above 240 km/h (149 mph)

4. Tire ply composition and mate-
rialThe number of layers or plies of rub-
ber-coated fabric in the tire. Tire
manufacturers also must indicate the
materials in the tire, which include
steel, nylon, polyester, and others.
The letter "R" means radial ply con-
struction; the letter "D" means diago-
nal or bias ply construction; and the
letter "B" means belted-bias ply con-
struction.
5. Maximum permissible inflation
pressureThis number is the greatest amount
of air pressure that should be put in
the tire. Do not exceed the maximum
permissible inflation pressure. Refer
to the Tire and Loading Information
label for recommended inflation
pressure.6. Maximum load ratingThis number indicates the maximum
load in kilograms and pounds that
can be carried by the tire. When
replacing the tires on the vehicle,
always use a tire that has the same
load rating as the factory installed
tire.7. Uniform tire quality grading The following information relates to
the tire grading system developed by
the Canada Motor Vehicle Safety
Stardard (CMVSS) for grading tires
by tread wear, traction and tempera-
ture performance.Tread wear
The tread wear grade is a compara-
tive rating based on the wear rate of
the tire when tested under controlled
conditions on a specified govern-
ment test course. For example, a tire
graded 150 would wear one-and-a-
half times as well on the government
course as a tire graded 100.
The relative performance of tires
depends upon the actual conditions
of their use. However, performance
may differ from the norm because of
variations in driving habits, service
practices and differences in road
characteristics and climate.
These grades are molded on the
side-walls of passenger vehicle tires.
The tires available as standard or
optional equipment on Kia vehicles
may vary with respect to grade.
WARNING -
Tire age
Tires degrade over time, even
when they are not being used.
Regardless of the remaining
tread, it is recommended that
tires generally be replaced after
six (6) years of normal service.
Heat caused by hot climates or
frequent high loading conditions
can accelerate the aging
process. Failure to follow this
warning can result in sudden tire
failure, which could lead to a
loss of control and an accident
involving serious injury or death.

LUBRICANT SPECIFICATIONSRecommended lubricants To help achieve proper engine and powertrain performance and
durability, use only lubricants of the proper quality. The correct
lubricants also help promote engine efficiency that results in
improved fuel economy.
Engine oils labeled Energy Conserving Oil are now available.
Along with other additional benefits, they contribute to fuel
economy by reducing the amount of fuel necessary to over-
come engine friction. Often, these improvements are difficult to
measure in everyday driving, but in a year’s time, they can offer
significant cost and energy savings.
Recommended SAE viscosity number ✽ ✽
NOTICEAlways be sure to clean the area around any filler plug, drain
plug, or dipstick before checking or draining any lubricant.
This is especially important in dusty or sandy areas and when
the vehicle is used on unpaved roads. Cleaning the plug and
dipstick areas will prevent dirt and grit from entering the
engine and other mechanisms that could be damaged. Engine oil viscosity (thickness) has an effect on fuel economy
and cold weather operating (starting and oil flow). Lower vis-
cosity engine oils can provide better fuel economy and cold
weather performance, however, higher viscosity engine oils are
required for satisfactory lubrication in hot weather. Using oils of
any viscosity other than those recommended could result in
engine damage.
When choosing an oil, consider the range of temperature your
vehicle will be operated in before the next oil change. Proceed
to select the recommended oil viscosity from the chart.
