What to do in an emergency
If the engine stalls at a cross-
road or crossing
If the engine stalls at a crossroad or
crossing, set the shift lever in the N
(Neutral) position and then push the
vehicle to a safe place.
If you have a flat tire while
driving
If a tire goes flat while you are driv-
ing:
1. Take your foot off the acceleratorpedal and let the vehicle slow
down while driving straight ahead.
Do not apply the brakes immedi-
ately or attempt to pull off the road
as this may cause a loss of con-
trol. When the vehicle has slowed
to such a speed that it is safe to do
so, brake carefully and pull off the
road. Drive off the road as far as
possible and park on firm level
ground. If you are on a divided
highway, do not park in the median
area between the two traffic lanes. 2. When the vehicle is stopped, turn
on your emergency hazard flash-
ers, set the parking brake and put
the transaxle in P (for Automatic
transaxle / Dual clutch transmis-
sion).
3. Have all passengers get out of the vehicle. Be sure they all get out on
the side of the vehicle that is away
from traffic.
4. When changing a flat tire, follow the instruction provided later in
this section.
If the engine stalls while driv-
ing
1. Reduce your speed gradually,keeping a straight line. Move cau-
tiously off the road to a safe place.
2. Turn on your emergency flashers.
3. Try to start the engine again. If your vehicle will not start, contact
an authorized Kia dealer or seek
other qualified assistance.
✽ ✽NOTICE
If there was a check engine light and
loss of power or stall and if safe to do
so, wait at least 10 seconds to restart
the vehicle after it stalls. This may
reset the car so it will no longer run
at low power (limp home) condition.

IF THE ENGINE WILL NOT START
If engine doesn't turn over or
turns over slowly
1. If your vehicle has an automatictransaxle / dual clutch transmis-
sion, be sure the shift lever is in N
(Neutral) or P (Park) and the
emergency brake is set.
2. Check the battery connections to be sure they are clean and tight.
3. Turn on the interior light. If the light dims or goes out when you oper-
ate the starter, the battery is dis-
charged.
4. Check the starter connections to be sure they are securely tight-
ened.
5. Do not push or pull the vehicle to start it. See instructions for "Jump
starting".
If engine turns over normally
but does not start
1. Check the fuel level.
2. With the ignition switch in theLOCK position, check all connec-
tors at the ignition coils and spark
plugs. Reconnect any that may be
disconnected or loose.
3. Check the fuel line in the engine compartment.
4. If the engine still does not start, call an authorized Kia dealer or
seek other qualified assistance.
WARNING - Push/
pull start
Do not push or pull the vehicle
to start it. Push or pull starting
may cause the catalytic con-
verter to overload and create a
fire hazard.

Jump starting procedure
1.Make sure the booster battery is12-volt and that its negative termi-
nal is grounded.
2.If the booster battery is in another vehicle, do not allow the vehicles to
come in contact.
3.Turn off all unnecessary electrical loads.
4.Connect the jumper cables in the exact sequence shown in the illus-
tration. First connect one end of a
jumper cable to the positive termi-
nal of the discharged battery (1),
then connect the other end to the
positive terminal of the booster
battery (2).
Proceed to connect one end of the
other jumper cable to the negative
terminal of the booster battery (3),
then the other end to a solid, sta-
tionary, metallic point (for example,
the engine lifting bracket) away
from the battery (4). Do not con-
nect it to or near any part that
moves when the engine is cranked. Do not allow the jumper cables to
contact anything except the correct
battery terminals or the correct
ground. Do not lean over the bat-
tery when making connections.
5.Start the engine of the vehicle with the booster battery and let it run at
2,000 rpm, then start the engine of
the vehicle with the discharged
battery.
If the cause of your battery discharg-ing is not apparent, you should haveyour vehicle checked by an author-ized Kia dealer.
Push-starting
Vehicles equipped with automatic
transaxle / dual clutch transmission
lock system cannot be push-started.
Follow the directions in this section
for jump-starting.
WARNING - Tow starting
vehicle
Never tow a vehicle to start it.
When the engine starts, the
vehicle can suddenly surge for-
ward and could cause a colli-
sion with the tow vehicle.
WARNING - Battery cables
Do not connect the jumper cable
from the negative terminal of the
booster battery to the negative
terminal of the discharged bat-
tery. This can cause the dis-
charged battery to overheat and
crack, releasing battery acid.

What to do in an emergency
IF THE ENGINE OVERHEATS
If your temperature gauge indicates
overheating, you experience a loss
of power, or hear loud pinging or
knocking, the engine will probably be
too hot. If this happens, you should:
1.Pull off the road and stop as soonas it is safe to do so.
2.Place the shift lever in P (for Automatic transaxle / Dual clutch
transmission) 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 com-
ing out from underneath the hood,
stop the engine. Do not open 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 cool-
ing fan is operating. 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 leak-
ing from the radiator, hoses or
under the vehicle. (If the air condi-
tioning 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 bro- ken 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 the
overheating, wait until the engine
temperature has returned to nor-
mal. If coolant has been lost, care-
fully 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 overheat-
ing. If overheating happens again,
call an authorized Kia dealer for
assistance.
Serious loss of coolant indicates
there is a leak in the cooling system
and this should be checked as soon
as possible by an authorized Kia
dealer.
WARNING - Under the hood
While the engine is running, keep hair,
hands and clothing
away from moving
parts such as the fan
and drive belts to pre-
vent injury.
WARNING - Radiator cap
Do not remove the
radiator cap when the
engine is hot. This may
result in coolant being
blown out of the open-
ing and cause serious
burns.

NOTICE
If the TPMS, Low Tire Pressure
indicator does not illuminate for 3
seconds when the ignition switch is
turned to the ON position or engine
is running, or if they remain illumi-
nated after coming on for approxi-
mately 3 seconds, take your vehicle
to your nearest authorized Kia deal-
er and have the system checked.
Low tire pressure
telltale
Low tire pressure position tell-
tale
When the tire pressure monitoring
system warning indicators are illumi-
nated, one or more of your tires is
significantly under-inflated.
If the telltale illuminates, 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 spare tire.
Then the TPMS malfunction indicator
and the Low Tire Pressure telltale
may turn on and illuminate after
restarting and about 20 minutes of
continuous driving before you have
the low pressure tire repaired and
replaced on the vehicle.
In winter or cold weather, the low tire
pressure telltale may be illuminated if
the tire pressure was adjusted to the
recommended tire inflation pressure
in warm weather. It does not mean
your TPMS is malfunctioning
because the decreased temperature
leads to a proportional lowering of
tire pressure.

5. Insert the sealant bottle into the
housing of the compressor (5) so
that the bottle is upright.
✽ ✽NOTICE
If a visable foreign object has punc-
tured the tire, do not remove it
before using Tire Mobility Kit.
6. Ensure that the compressor is
switched off, position 0.
7 Connect between compressor and the vehicle power outlet using the
cable and connectors.
8. With the engine start/stop button position on or ignition switch posi-
tion on, switch on the compressor
and let it run for approximately 5~7
minutes to fill the sealant up to
proper pressure. (refer to the Tire
and Wheels, chapter 9). The infla-
tion pressure of the tire after filling
is unimportant and will be
checked/corrected later. Be careful
not to overinflate the tire and stay
away from the tire when filling it. 9. Switch off the compressor.
10. Detach the hoses from the
sealant bottle connector and
from the tire valve.
Return the Tire Mobility Kit to its stor-
age location in the vehicle.
OJF065024OJFA065038
WARNING
Carbon monoxide poisoning
and suffocation is possible if
the engine is left running in a
poorly ventilated or unventilat-
ed location (such as inside a
building).
WARNING - Tire pressure
Do not attempt to drive your
vehicle if the tire pressure is
below 200kPa (29 psi). This
could result in an accident due
to sudden tire failure.

OWNER MAINTENANCE
The following lists are vehicle checks
and inspections that should be per-
formed by the owner or an author-
ized Kia dealer at the frequencies
indicated to help ensure safe,
dependable operation of your vehi-
cle.
Any adverse conditions should be
brought to the attention of your deal-
er as soon as possible.

ranties and you may be charged for
labor, parts and lubricants used.Owner maintenance schedule
When you stop for fuel:
Check the engine oil level.
Check the coolant level in coolantreservoir.
Check the windshield washer fluid level.
Look for low or under-inflated tires.
While operating your vehicle:
Note any changes in the sound of the exhaust or any smell of
exhaust fumes in the vehicle.
Check for vibrations in the steering wheel. Notice any increased steer-
ing effort or looseness in the steer-
ing wheel, or change in its straight-
ahead position.
Notice if your vehicle constantly turns slightly or “pulls” to one side
when traveling on smooth, level
road.
When stopping, listen and check for unusual sounds, pulling to one
side, increased brake pedal travel
or “hard-to-push” brake pedal.
If any slipping or changes in the operation of your transaxle occurs,
check the transaxle fluid level.
Check the automatic transaxle P (Park) function.
