When you are ready to leave after park-
ing on a hill
1. With the manual transaxle in Neutral
or 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 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 nutsand 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 indicatesover-heating, switch off the A/Cand stop the vehicle in a safe area
to cool down the engine.
When towing, check the transaxle fluid more frequently.
If your vehicle is not equipped with an air conditioner, you
should install a condenser fan toimprove engine performancewhen towing a trailer.

What to do in an emergency

IF THE ENGINE OVERHEATS
If your temperature gauge indicates over-
heating, you will experience a loss of
power, or hear loud pinging or knocking,
the engine is probably too hot. If this hap-
pens, you should:
1. Pull off the road and stop as soon as it is safe to do so.
2. Place the shift lever in P (automatic transaxle) or Neutral (manual
transaxle) and set the parking brake. If
the air conditioning is on, turn it off.
3. If engine coolant is running out under the vehicle or steam is coming out
from the hood, stop the engine. Do notopen the hood until the coolant has
stopped running or the steaming has
stopped. If there is no visible loss of
engine coolant and no steam, leave
the engine running and check to be
sure the engine cooling fan is operat-
ing. If the fan is not running, turn the
engine off. 4. Check to see if the water pump drive
belt is missing. If it is not missing,
check to see that it is tight. If the drive
belt seems to be satisfactory, check for
coolant leaking from the radiator,
hoses or under the vehicle. (If the air
conditioning had been in use, it is nor-
mal for cold water to be draining from
it when you stop).
5. If the water pump drive belt is broken or engine coolant is leaking out, stop the engine immediately and call the
nearest authorized KIA dealer for
assistance. 6. If you cannot find the cause of over-
heating, wait until the engine tempera-
ture has returned to normal. Then, ifcoolant has been lost, carefully add
coolant to the reservoir to bring the
fluid level in the reservoir up to the
halfway mark.
7. Proceed with caution, keeping alert for further signs of overheating. If over-heating happens again, call an author-
ized KIA dealer for assistance.
WARNING
While the engine is running, keep
hair, hands and clothing away from
moving parts such as the fan and
drive belts to prevent injury.
WARNING
Do not remove the radiator cap
when the engine is hot. This can
allow coolant to be blown out of the
opening and cause serious burns.
CAUTION
Serious loss of coolant indicates there is a leak in the cooling systemand this should be checked as soonas possible by an authorized KIA dealer.

Maintenance
Engine compartment precautions (Diesel engine)
The piezo injector operates at highvoltage (maximum 200v). Therefore,
the following accidents may occur.
- Direct contact with the injector or
injector wiring may cause electric
shock or damage your muscle or
nerve system.
- The electromagnetic wave from the operating injector may cause the arti-
ficial heart pacemaker to malfunction.
Follow the safety tips provided below, when you are checking the engine
room while the engine is running.
- Do not touch the injector, injector
wirings, and the engine computer
while the engine is running.
- Do not remove the injector connector while the engine is running.
- People using pacemakers must not go near the engine while the engine
is starting or running.
WARNING - Maintenance
work
Performing maintenance work on a vehicle can be dangerous. You
can be seriously injured while
performing some maintenance
procedures. If you lack sufficient
knowledge and experience or the
proper tools and equipment to do
the work, have it done by an
authorized KIA dealer.
Working under the hood with the engine running is dangerous. It
becomes even more dangerous
when you wear jewelry or loose
clothing. These can become
entangled in moving parts and
result in injury. Therefore, if you
must run the engine while work-
ing under the hood, make certain
that you remove all jewelry (espe-
cially rings, bracelets, watches,
and necklaces) and all neckties,
scarves, and similar loose cloth-
ing before getting near theengine or cooling fans.WARNING - Diesel Engine
Never work on the injection system with the engine running or within30 seconds after shutting off the
engine. High-pressure pump, rail,
injectors and high-pressure pipes
are subject to high pressure even
after the engine stopped. The fuel
jet produced by fuel leaks may
cause serious injury, if it touches
the body. People using pacemakers
should not move more than 30cm
closer to the ECU or wiring harness
within the engine room while the
engine is running, since the high
currents in the electronic engine
control system produce consider-
able magnetic fields.

Vapor hose and fuel filler cap
The vapor hose and fuel filler cap should
be inspected at those intervals specified
in the maintenance schedule. Make sure
that a new vapor hose or fuel filler cap iscorrectly replaced.
Vacuum crankcase ventilation hoses (if equipped)
Inspect the surface of hoses for evidence
of heat and/or mechanical damage. Hard
and brittle rubber, cracking, tears, cuts,
abrasions, and excessive swelling indi-
cate deterioration. Particular attention
should be paid to examine those hose
surfaces nearest to high heat sources,
such as the exhaust manifold. Inspect the hose routing to assure that the hoses do not come in contact with
any heat source, sharp edges or movingcomponent which might cause heat dam-
age or mechanical wear. Inspect all hose
connections, such as clamps and cou-
plings, to make sure they are secure, and
that no leaks are present. Hoses should
be replaced immediately if there is any
evidence of deterioration or damage. Air cleaner filter
A Genuine KIA air cleaner filter is recom- mended when the filter is replaced.
Spark plugs (for gasoline engine)
Make sure to install new spark plugs of
the correct heat range.
Valve clearance
(for gasoline engine)
Inspect for excessive valve noise and/or
engine vibration and adjust if necessary.
An authorized KIA dealer should perform
the operation. Cooling system
Check the cooling system components,
such as the radiator, coolant reservoir,
hoses and connections for leakage and
damage. Replace any damaged parts. Coolant The coolant should be changed at the
intervals specified in the maintenance
schedule.
Manual transaxle fluid (if equipped)
Inspect the manual transaxle fluid
according to the maintenance schedule.
Automatic transaxle fluid (if equipped)
Automatic transaxle fluid should not be
checked under normal usage conditions.
But in severe conditions, the fluid should
be changed at an authorized KIA dealerin accordance to the scheduled mainte-
nance at the beginning of this chapter.
✽✽
NOTICE
Automatic transaxle fluid color is basi-
cally red.
As the vehicle is driven, the automatic
transaxle fluid will begin to look darker.
It is normal condition and you should
not judge the need to replace the fluid
based upon the changed color.
CAUTION
The use of a non-specified fluid could result in transaxle malfunc-
tion and failure.
Use only specified automatictransaxle fluid. (Refer to “Recommended lubricants andcapacities” in section 8.)

Maintenance
Changing the engine oil and filter
Have engine oil and filter changed by an
authorized KIA dealer according to theMaintenance Schedule at the beginningof this section.The high-pressure cooling system has a
reservoir filled with year round antifreeze
coolant. The reservoir is filled at the fac-
tory.
Check the antifreeze protection and
coolant level at least once a year, at thebeginning of the winter season, and
before traveling to a colder climate.
Checking the coolant level
WARNING
Used engine oil may cause skin irri- tation or cancer if left in contact
with the skin for prolonged periods
of time. Used engine oil contains
chemicals that have caused cancer
in laboratory animals. Always pro-
tect your skin by washing your
hands thoroughly with soap and
warm water as soon as possibleafter handling used oil.
ENGINE COOLANT
WARNING - Removing
radiator cap
Never attempt to remove the radi- ator cap while the engine is oper-
ating or hot. Doing so might leadto cooling system and engine
damage. Also, hot coolant orsteam could cause serious per-
sonal injury.
(Continued)
(Continued)
Turn the engine off and wait untilit cools down. Use extreme care
when removing the radiator cap.
Wrap a thick towel around it, and
turn it counterclockwise slowly to
the first stop. Step back while the
pressure is released from the
cooling system. When you aresure all the pressure has been
released, press down on the cap,
using a thick towel, and continue
turning counterclockwise to
remove it.
Even if the engine is not operat- ing, do not remove the radiatorcap or the drain plug while the
engine and radiator are hot. Hot
coolant and steam may still blow
out under pressure, causing seri-
ous injury.

Check the condition and connections of all cooling system hoses and heater
hoses. Replace any swollen or deterio-
rated hoses.
The coolant level should be filled
between F and L marks on the side of the
coolant reservoir when the engine iscool.
If the coolant level is low, add enough
specified coolant to provide protection
against freezing and corrosion. Bring the
level to F, but do not overfill. If frequent
additions are required, see an authorized
KIA dealer for a cooling system inspec-tion.
Recommended engine coolant
Use only soft (distilled) water in the
coolant mixture.
The engine in your vehicle has alu- minum engine parts and must be pro-
tected by an ethylene-glycol-based
coolant to prevent corrosion and freez-ing.
DO NOT USE alcohol or methanol coolant or mix them with the specifiedcoolant.
Do not use a solution that contains more than 60% antifreeze or less than
35% antifreeze, which would reduce
the effectiveness of the solution. For mixture percentage, refer to the fol-
lowing table.
