What to do in an emergency
(Continued)
Be sure to use the correctfront and rear jacking posi-
tions on the vehicle; never
use the bumpers or any other
part of the vehicle for jack
support.
The vehicle can easily roll off the jack causing serious
injury or death. No person
should place any portion of
their body under a vehicle that
is supported only by a jack;
use vehicle support stands.
Do not start or run the engine while the vehicle is on the
jack.
Do not allow anyone to remain in the vehicle while it is on the
jack.
Make sure any children pres- ent are in a secure place away
from the road and from the
vehicle to be raised with the
jack.

Jacking instructions
The jack is provided for emergency
tire changing only.
To prevent the jack from “rattling”
while the vehicle is in motion, store it
properly.
Follow jacking instructions to reduce
the possibility of personal injury.
WARNING- Changing tires
Never attempt vehicle repairs in the traffic lanes of a public
road or highway.
Always move the vehicle com- pletely off the road and onto
the shoulder before trying to
change a tire. The jack should
be used on level firm ground.
If you cannot find a firm, level
place off the road, call a tow-
ing service company for
assistance.

Owner maintenance precautions
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, sev-
eral procedures can be done only by an
authorized KIA dealer with special tools.
✽ ✽NOTICE
Improper owner maintenance during
the warranty period may affect warran-
ty coverage. For details, read the sepa-
rate Warranty & Maintenance book
provided with the vehicle. If you're
unsure about any servicing or mainte-
nance procedure, have it done by an
authorized KIA dealer.
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 the
engine or cooling fans.

Check the engine oil level.
Check coolant level in coolant reser-voir.
Check the windshield washer fluid level.
Look for low or under-inflated tires.
G030102AUN
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 steering
effort or looseness in the steering
wheel, or change in its straight-ahead
position.
Notice if your vehicle constantly turns slightly or “pulls” to one side when trav-
eling 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 oper- ation of your transaxle occurs, check
the transaxle fluid level.
