Various driving situations, which you
may encounter in SMART mode
The driving mode automatically
changes to ECO mode after a cer-
tain period of time, when you gen-
tly depress the accelerator pedal
(Your driving is categorized to be
mild.).
The driving mode automatically changes from SMART ECO mode
to SMART COMFORT mode after
a certain period of time, when you
sharply or repetitively depress the
accelerator pedal.
The driving mode automatically changes to SMART COMFORT
mode with the same driving pat-
terns, when the vehicle starts to
drive on an upward slope of a cer-
tain angle. The driving mode auto-
matically returns to SMART ECO
mode, when the vehicle enters a
leveled road. The driving mode automatically
changes to SMART SPORT, when
you abruptly accelerate the vehicle
or repetitively operate the steering
wheel (Your driving is categorized
to be sporty.). In this mode, your
vehicle drives in a lower gear for
abrupt accelerating/decelerating
and increases the engine brake
performance.
You may still sense the engine brake performance, even when you
release the accelerator pedal in
SMART SPORT mode. It is
because your vehicle remains to
be in a lower gear over a certain
period of time for next acceleration.
Thus, it is a normal driving situa-
tion, not indicating any malfunc-
tion.
The driving mode automatically changes to SMART SPORT mode
only in harsh driving situations. In
most of the normal driving situa-
tions, the driving mode sets to be
either in SMART ECO mode or in
SMART COMFORT mode. Limitation of SMART mode
The SMART mode may be limited in
following situations. (The OFF indica-
tor illuminates in those situations.)
The driver manually moves the
shift lever : It deactivates SMART
mode. The vehicle drives, as the
driver manually moves the shift
lever.
The cruise control is activated : The cruise system may deactivate
the SMART mode. When a higher
system is set by the cruise system,
it starts to control vehicle speed
and deactivates SMART mode.
(SMART mode is not deactivated
just by activing the cruise system.)
The transmission oil temperature is either extremely low or extremely
high : The SMART mode can be
active in most of the normal driving
situations. However, an extremely
high/ low transmission oil tempera-
ture may temporarily deactivate the
SMART mode, because the trans-
mission condition is out of normal
operation condition.

What to do in an emergency
46
IF THE ENGINE WILL NOT START
If engine doesn't turn over or
turns over slowly
1. If your vehicle has an automatictransmission / dual clutch trans-
mission, 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.

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.
These Owner Maintenance Checks
are generally not covered by war-
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 transmission
occurs, check the transmission
fluid level.
Check the automatic transmis- sion/dual clutch transmission P
(Park) function.
Check the parking brake.
Check for fluid leaks under your vehicle (water dripping from the air
conditioning system during or after
use is normal).
WARNING- Hot coolant
Be careful when checking your
engine coolant level when the
engine is hot. Scalding hot
coolant and steam may blow
out under pressure.
