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.
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 hybrid system 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.

Disc brake pads should be inspected
for wear whenever tires are rotated.
Rotate radial tires that have an
asymmetric tread pattern only from
front to rear and not from right to left.
Wheel alignment and tire bal-
ance
The wheels on your vehicle were
aligned and balanced carefully at the
factory to give you the longest tire life
and best overall performance.
In most cases, you will not need to
have your wheels aligned again.
However, if you notice unusual tire
wear or your vehicle pulling one way
or the other, the alignment may need
to be reset.
If you notice your vehicle vibrating
when driving on a smooth road, your
wheels may need to be rebalanced.
WARNING - Mixing tires
Do not use the compact spare tire (if equipped) for tire rota-
tion.
Do not mix bias ply and radial ply tires under any circum-
stances. This may cause
unusual handling characteris-
tics.
CAUTION - Wheel weight
Improper wheel weights candamage your vehicle's alu-minum wheels. Use onlyapproved wheel weights.
