because ice has formed around it,
tap lightly or push on the lid to
break the ice and release the lid. Do
not pry on the lid. If necessary,
spray around the lid with an
approved de-icer fluid (do not use
radiator anti-freeze) or move the
vehicle to a warm place and allow
the ice to melt.
1. Stop the engine.
2. To open the fuel filler lid, push the
fuel filler lid opener button.
3. Pull open the fuel filler lid (1).
4. To remove the cap, turn the fuel filler cap (2) counterclockwise(3).
5. Refuel as needed.
Closing the fuel filler lid
1. To install the cap, turn it clockwise until it “clicks” once. This indicates
that the cap is securely tightened.
2. Close the fuel filler lid and push it in lightly making sure that it is
securely closed.
✽ ✽NOTICE
There may be an intermittent noise
near the refueling hole while the
engine is idling if the fuel cap is not
closed securely. This occurs normal-
ly with the OBD system.
✽ ✽NOTICE
When refueling on unlevel ground,
the fuel gauge may not point to the F
position.
It is not a malfunction. If you move
your vehicle to a level ground, the fuel
gauge will move to the full position.

Outside rearview mirror
Be sure to adjust the mirror angles
before driving.
Your vehicle is equipped with both
left-hand and right-hand outside
rearview mirrors. The mirrors can be
adjusted remotely with the remote
switch. The mirror heads can be fold-
ed back to prevent damage during an
automatic vehicle wash or when
passing through a narrow street.
The right outside rearview mirror is
convex. Objects seen in the mirror
are closer than they appear.
Use your interior rearview mirror or
direct observation to determine the
actual distance of following vehicles
when changing lanes. If the mirror is jammed with ice, do
not adjust the mirror by force. Use an
approved spray de-icer (not radiator
antifreeze) to release the frozen
mechanism or move the vehicle to a
warm place and allow the ice to melt.
Adjusting outside rearview mirror
The electric remote control mirror
switch allows you to adjust the posi-
tion of the left and right outside
rearview mirrors. To adjust the posi-
tion of either mirror, press the R or L
button (1) to select the right side mir-
ror or the left side mirror, then press a
corresponding point ( ) on the mir-
ror adjustment control to position the
selected mirror up, down, left or right.
After adjustment, press the R or L
button again to prevent the inadver-
tent adjustment.

What to do in an emergency
IF THE ENGINE OVERHEATS
If your temperature gauge indicates
overheating, you will experience a
loss of power, or hear loud pinging or
knocking, the engine is probably too
hot. If this happens, you should:
1. Turn on the emergency warningflasher and stop in a safe place.
Move the shift lever to P (Park)
and engage the parking brake.
2. If hot steam does not come out from the engine room, carefully
open the engine room and check
whether the water pump connec-
tor is properly engaged. If the con-
nector is not properly engaged,
stop the engine immediately and
properly engage the connector.
Then, turn the engine on.
3. Turn on the air conditioner. 4. If the “HEV Warning” light turns on
in the driver instrument cluster, or
engine coolant or hot steam emits
from the engine coolant filler, stop
the engine immediately. Then, call
the nearest authorized Kia dealer
for assistance. If the “Engine
Warning” light remains illuminated
or the engine coolant is not flowing
out, keep the engine running.
Open the engine hood for ventila-
tion to help cool down the engine. 5. Check the coolant temperature
gauge on the instrument cluster to
make sure the coolant tempera-
ture is sufficiently cooled down. If
the engine coolant level is low,
please check the connecting parts
between the radiator hose, heater
hose, and water pump for any
signs of leakage. When there is no
sign of leakage, please refill the
engine coolant. If causes and
signs of engine overheating such
as warning light illumination,
engine coolant leakage, or cooling
fan malfunction are found, stop the
vehicle the earliest. Then, call the
nearest authorized Kia dealer for
assistance.
WARNING
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.
