4Air conditioning system opera-
tion tips  If the vehicle has been parked in direct
sunlight during hot weather, open the
windows for a short time to let the hot
air inside the vehicle escape.
 To help reduce moisture inside of win-
dows on rainy or humid days, decrease
the humidity inside the vehicle by oper-
ating the air conditioning system.
 During air conditioning system opera-
tion, you may occasionally notice a
slight change in engine speed as the
air conditioning compressor cycles.
This is a normal system operation
characteristic.
 Use the air conditioning system every
month if only for a few minutes to
ensure maximum system perform-
ance.
 When using the air conditioning sys-
tem, you may notice clear water drip-
ping (or even pudding) on the ground
under the passenger side of the vehi-
cle. This is a normal system operation
characteristic. 
Operating the air conditioning system
in the recirculated air position does
provide maximum cooling, however,
continual operation in this mode may
cause the air inside the vehicle to
become stale.
Checking the amount of air con-
ditioner refrigerant and compres-
sor lubricantWhen the amount of refrigerant is low,
the performance of the air conditioning is
reduced. Overfilling also has a bad influ-
ence on the air conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by an
authorized Kia dealer.✽ ✽
NOTICEWhen the performance of the air condi-
tioning system is reduced it is important
that the correct type and amount of oil
and refrigerant is used. Otherwise, dam-
age to the compressor and abnormal
system operation may occur.
CAUTION
The air conditioning system should
be serviced by an authorized Kiadealer. Improper service may cause serious injury to the person per-forming the service.

Driving tips
When you are ready to leave afterparking on a hill 1. With the automatic transaxle in P (Park), apply your brakes and hold the
brake pedal down while you:
 Start your engine;
 Shift into gear; and
 Release the parking brake.
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.

4. The coolant level should then bechecked. If the level in the reservoir is
low, look for leaks at the radiator hoses
and connections, heater hoses and
connections, radiator, and water
pump. If you find a major leak or anoth-
er problem that may have caused the
engine to overheat, do not operate the
engine until it has been corrected. Call
an authorized Kia dealer for assis-
tance. If you do not find a leak or other
problem, carefully add coolant to the
reservoir.If the engine frequently overheats, havethe cooling system checked and repairedby an authorized Kia dealer.
Jump starting Jump starting can be dangerous if done
incorrectly. Therefore, to avoid harm to
yourself or damage to your vehicle or
battery, follow the jump starting proce-
dures. If in doubt, we strongly recom-
mend that you have a competent techni-
cian or towing service jump start your
vehicle.✽ ✽ NOTICEUse only a 12-volt jumper system. You
can damage a 12-volt starting motor,
ignition system, and other electrical
parts beyond repair by use of a 24-volt
power supply (either two 12-volt batter-
ies in series or a 24-volt motor generator
set).
WARNING
- Removing
radiator cap
Do not remove the radiator cap
when the engine and radiator are
hot. Scalding hot coolant and steam
may blow out under pressure. This
could cause serious injury.
EMERGENCY STARTING
WARNING
- Battery
• Keep all flames or sparks away
from the battery. The battery pro-
duces hydrogen gas which may
explode if exposed to flame or
sparks.
 Do not attempt to jump start the vehicle if the discharged battery
is frozen or if the electrolyte level
is low; the battery may rupture or
explode.
WARNING
- Battery
Never attempt to check the elec-
trolyte level of the battery as this
may cause the battery to rupture or
explode causing serious injury.

In case of an emergency
TOWINGIf emergency towing is necessary, we
recommend having it done by an author-
ized Kia dealer or a commercial tow-truck
service. Proper lifting and towing proce-
dures are necessary to prevent damage
to the vehicle. The use of wheel dollies or
flatbed equipment is recommended.For trailer towing guidelines information,refer to section 5 “Driving Tips”.
It is acceptable to tow the vehicle with the
rear wheels on the ground (without dol-
lies) and the front wheels off the ground.
When being towed by a commercial tow
truck and wheel dollies are not used, the
front of the vehicle should always be lift-
ed, not the rear.
✽ ✽ NOTICE• Do not tow the vehicle backwards
with the front wheels on the ground as
this may cause damage to the vehicle.
• Do not tow with sling-type equipment. Use wheel lift or flatbed equipment.

6If towing service is not available in an
emergency, your vehicle may be tem-
porarily towed using a cable or chain
secured to the emergency towing hook
under the front or rear of the vehicle. Use
extreme caution when towing the vehicle.
A driver must be in the vehicle to steer it
and operate the brakes.
Towing in this manner may be done only
on hard-surfaced roads for a short dis-
tance and at low speeds. Also, the
wheels, axles, power train, steering and
brakes must all be in good condition.
 Do not use the tow hooks to pull a vehi-
cle out of mud, sand or other condi-
tions from which the vehicle cannot be
driven out under its own power.
 Avoid towing a vehicle heavier than the vehicle doing the towing.
 The drivers of both vehicles should com- municate with each other frequently.✽ ✽ NOTICE• Attach a towing strap to the tow hook.
• Using a portion of the vehicle other
than the tow hooks for towing may
damage the body of your vehicle.
• Use only a cable or chain specifically intended for use in towing vehicles.
Securely fasten the cable or chain to
the towing hook provided.
 Before emergency towing, check that
the hook is not broken or damaged.
 Fasten the towing cable or chain securely to the hook.
 Do not jerk the hook. Apply steady and even force.
 To avoid damaging the hook, do not pull from the side or at a vertical angle.
Always pull straight ahead.
 Use a towing strap less than 5 m (16feet) long. Attach a white or red cloth
(about 30 cm (12 inches) wide) in the
middle of the strap for easy visibility.
 Drive carefully so that the towing strap is not loosened during towing.
CAUTION
Use extreme caution when towingthe vehicle.
 Avoid sudden starts or erratic driving maneuvers which wouldplace excessive stress on theemergency towing hook and tow- ing cable or chain. The hook andtowing cable or chain may break and cause serious injury or dam-age.
 If the towing vehicle does not move easily, do not forcibly continue thetowing. Contact an authorized Kiadealer or a commercial tow truckservice for assistance.
 Tow the vehicle as straight ahead as possible.
 Keep away from the vehicle dur- ing towing.

In case of an emergency
Low tire pressure
indicator
When the tire pressure monitoring
system warning indicator is illuminat-
ed, one or more of your tires is sig-
nificantly under-inflated. Immediately
reduce your speed, avoid hard cor-
nering and anticipate increased stop-
ping distances. You should stop and
check your tires as soon as possible.
Inflate the tires to the proper pres-
sure as indicated on the vehicle’s
placard or tire inflation pressure label
located on the driver’s side center pil-
lar outer panel. If you cannot reach a
service station or if the tire cannot
hold the newly added air, replace the
low pressure tire with the compact
spare tire. Because the compact
spare tire is not equipped with a tire
pressure sensor, the TPMS malfunc-
tion indicator may go on and the Low
Tire Pressure indicator may go off
after restarting and about 20 minutes
of continuous driving.
TPMS (Tire pressure
monitoring system)
malfunctionThe TPMS malfunction indicator
comes on and stays on when there is
a problem with the Tire Pressure
Monitoring System. If Front Left sen-
sor fails, the TPMS malfunction indica-
tor comes on, but if Front Right, Rear
Left, or Rear Right tire is under-inflat-
ed, the low tire pressure indicator may
come on with the TPMS malfunction
indicator.
Have the system checked by an
authorized Kia dealer as soon as pos-
sible to determine the cause of the
problem.
WARNING
- Low pressuredamage
Significantly low tire pressure
makes the vehicle unstable and
can contribute to loss of vehicle
control and increased braking
distances.
Continued driving on low pres-
sure tires can cause the tires to
overheat and fail.
TPMS
CAUTION
In winter or cold weather, the low tire pressure indicator maybe illuminated if the tire pres-sure was adjusted to the recom-mended tire inflation pressurein warm weather. It does notmean your TPMS is malfunction-ing because the decreased tem-perature leads to a proportionallowering of tire pressure.
When you drive your vehiclefrom a warm area to a cold areaor from a cold area to a warmarea, or the outside temperatureis greatly higher or lower, youshould check the tire inflationpressure and adjust the tires tothe recommended tire inflationpressure.

✽
NOTICEThe TPMS malfunction indicator
may be illuminated if the vehicle is
moving around electric power sup-
ply cable or radio transmitter such
as police stations, government and
public offices, broadcasting stations,
military installations, airports, or
transmitting tower, etc. which can
interfere with normal operation of
the Tire Monitoring System
(TPMS).
Changing a tire with TPMSIf you have a flat tire, the Low Tire
Pressure indicator will come on.
Have the flat tire repaired by an
authorized Kia dealer as soon as
possible or replace the flat tire with
the compact spare tire.✽ ✽NOTICENEVER use a puncture-repairing
agent to repair and/or inflate a low
pressure tire. If used, you will have
to replace the tire pressure sensor. Each wheel is equipped with a tire
pressure sensor mounted inside the
tire behind the valve stem. You must
use TPMS specific wheels. It is rec-
ommended that you always have
your tires serviced by an authorized
Kia dealer as soon as possible. After you replace the low pressure
tire with the compact spare tire, the
TPMS malfunction indicator may illu-
minate after restarting and about 20
minutes of continuous driving
because the compact spare tire does
not have a sensor.
Once the low pressure tire is re-inflat-
ed to the recommended pressure
and installed on the vehicle, the
TPMS malfunction indicator and the
low tire pressure indicator will be
extinguished. If the low pressure and
TPMS malfunction indicators are not
extinguished after about 20 minutes
of continuous driving, please visit an
authorized Kia dealer.
You may not be able to identify a low
tire by simply looking at it. Always use
a good quality tire pressure gauge to
measure the tire's inflation pressure.
Please note that a tire that is hot
(from being driven) will have a higher
pressure measurement than a tire
that is cold (from sitting stationary for
at least 3 hours and driven less than
1.6 km (1 mile) during that 3 hour
period). Allow the tire to cool before
measuring the inflation pressure.
