Owner maintenance precau-
tions
Improper or incomplete service may
result in problems. This section gives
instructions only for the maintenance
items that are easy to perform.
As explained earlier in this section,
several procedures can be done only
by an authorized Kia dealer with spe-
cial tools.
✽ ✽
NOTICE
Improper owner maintenance dur-
ing the warranty period may affect
warranty coverage. For details, read
the separate Warranty & Consumer
Information manual provided with
the vehicle. If you're unsure about
any servicing or maintenance proce-
dure, have it done by an authorized
Kia dealer.
WARNING- Maintenance
work
Do not wear jewelry or loose
clothing while working under
the hood of your vehicle with
the engine running. These can
become entangled in moving
parts, if you must run the
engine while working under the
hood, make certain that you
remove all jewelry (especially
rings, bracelets, watches, and
necklaces) and all neckties,
scarves, and similar loose
clothing before getting near the
engine or cooling fans.WARNING- Touching
metal parts
Do not touch metal parts
(including strut bars) while the
engine is operating or hot.
Doing so could result in serious
bodily injury. Turn the engine off
and wait until the metal parts
cool down to perform any main-
tenance work on the vehicle.

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 coolant level in coolant
reservoir.
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, take your vehicle to an
authorized Kia dealer.
Check the 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.
WARNING
When you open the engine
hood, turn the Hybrid system
off. If not, it may result in death
or serious injury because of the
high voltage flow.
