speeds. (Steep accelerating and
decelerating should be avoided.)
•Always start the vehicle with your
foot on the brake pedal. Do not
depress the accelerator while
starting the vehicle. Do not race
the engine while warming it up.

(Continued)
•If the "" indicator turns off
while you are in motion, do not at‐
tempt to move the shift lever to
the P (Park) position.
If traffic and road conditions per‐
mit, you may put the shift lever in
the N (Neutral) position while the
vehicle is still moving and press
the Engine Start/Stop button in an
attempt to restart the hybrid sys‐
tem.
•Do not push or tow your vehicle to
start the hybrid system.
NOTICE
•If the battery is weak or the smart
key does not work correctly, you
can start the hybrid system by
pressing the engine start/stop
button with the smart key.
The side with the lock button
should be contacted directly.
When you press the engine start/
stop button directly with the
smart key, the smart key should
contact the button at a right an‐
gle.
•When the stop lamp fuse is blown,
you cannot start the hybrid sys‐
tem normally.
Replace the fuse with a new one.
If it is not possible, you can start
the hybrid system by pressing the
engine start/stop button for 10
seconds while it is in the ACC posi‐
tion. The engine can start without

•Always check the surroundingareas near your vehicle for people,especially children, before shiftinga vehicle into D (Drive) or R (Re‐verse).
•Before leaving the driver’s seat, al‐ways make sure the shift lever isin the P (Park) position; then setthe parking brake fully and shutthe engine off. Unexpected andsudden vehicle movement can oc‐cur if these precautions are notfollowed in the order identified.
•Do not use the engine brake (shift‐ing from a high gear to lower gear)rapidly on slippery roads.The vehicle may slip causing an ac‐cident.
CAUTION
•To avoid damage to your trans‐axle, do not accelerate the enginein R (Reverse) or any forward gearposition with the brakes on.
(Continued)
(Continued)
•When stopped on an uphill grades,do not hold the vehicle stationarywith engine power. Use the brakepedal or the parking brake.
•Do not shift from N (Neutral) or P(Park) into D (Drive), or R (Reverse)when the engine is above idlespeed.
Transaxle ranges
The indicator lights in the instrument
cluster displays the shift lever position when the engine start/stop button
switch is in the ON position.
P (Park)
Always come to a complete stop before
shifting into P (Park). This position locks the transaxle and prevents the
front wheels from rotating.
To shift from P (Park), you must de‐
press firmly on the brake pedal and make sure your foot is off the acceler‐
ator pedal.
If you have done all of the above andstill cannot shift the lever out of P(Park), see L

Shift-lock override
If the shift lever cannot be moved from
the P (Park) position into R (Reverse) position with the brake pedal de‐
pressed, continue depressing the brake,
then do the following: 1. Place the engine start/stop button switch in the LOCK/OFF position.
2. Apply the parking brake.
3. Carefully remove the cap (1) cover‐ ing the shift-lock release access
hole.
4. Insert a tool (e.g. flathead screw‐ driver) into the access hole andpress down on the tool.
5. Move the shift lever.
6. Remove the tool from the shift- lock override access hole then in‐
stall the cap.
7. We recommend that the system be inspected by an authorized Kia
dealer.
Good driving practices
• Never move the shift lever from P (Park) or N (Neutral) to any other po‐
sition with the accelerator pedal de‐ pressed. • Never move the shift lever into P
(Park) when the vehicle is in motion.
• Be sure the vehicle is completely stopped before you attempt to shift
into R (Reverse) or D (Drive).
• Never take the vehicle out of gear and coast down a hill. This may beextremely hazardous. Always leave
the vehicle in gear when moving.
• Do not "ride" the brakes. This can cause them to overheat and malfunc‐
tion. Instead, when you are driving
down a long hill, slow down and shift to a lower gear. When you do this,
engine braking will help slow down
the vehicle.
• Slow down before shifting to a lower gear. Otherwise, the lower gear maynot be engaged.
• Always use the parking brake. Do not depend on placing the transaxle in P
(Park) to keep the vehicle from mov‐
ing. • Exercise extreme caution when driv‐
ing on a slippery surface. Be especial‐ly careful when braking, accelerating
or shifting gears. On a slippery sur‐
face, an abrupt change in vehicle
speed can cause the drive wheels to
lose traction and the vehicle to go out of control.
• Optimum vehicle performance and economy is obtained by smoothly de‐
pressing and releasing the accelera‐
tor pedal.
WARNING
•Always buckle-up! In a collision, anunbelted occupant is significantlymore likely to be seriously injuredor killed than a properly belted oc‐cupant.
•Avoid high speeds when corneringor turning.
•Do not make quick steering wheelmovements, such as sharp lanechanges or fast, sharp turns.
•The risk of rollover is greatly in‐creased if you lose control of yourvehicle at highway speeds.

Move the shiftlever into the P (Park) position,then apply the parking brake, andplace the Engine Start/Stop buttonin the OFF position.Vehicles with the parking brakenot fully engaged are at risk formoving inadvertently and causinginjury to yourself or others.
•Never allow anyone who is unfa‐miliar with the vehicle to touch theparking brake. If the parking brakeis released unintentionally, seriousinjury may occur.
•All vehicles should always have theparking brake fully engaged whenparking to avoid inadvertentmovement of the vehicle whichcan injure occupants or pedes‐trians.

or ON position.
Before driving, be sure the parking
brake is fully released and the brake warning light is off.
If the brake warning light remains on
after the parking brake is released
while the hybrid system is on, there may be a malfunction in the brake sys‐
tem. Immediate attention is necessary. If at all possible, cease driving the vehi‐
cle immediately. If that is not possible, use extreme caution while operating
the vehicle and only continue to drive
the vehicle until you can reach a safe location or repair shop.

If the EPB is applied while Auto Hold is
activated because of ESC (Electronic Stability Control) signal, a warning will
sound and a message will appear.
EPB malfunction indicator (if
equipped)
0+'
This warning light illuminates if the en‐
gine start/stop button is changed to the ON position and goes off in approxi‐
mately 3 seconds if the system is oper‐
ation normally. If the EPB malfunction indicator re‐
mains on, comes on while driving, or
does not come on when the ignition
switch or the engine start/stop button is changed to the ON position, this indi‐
cates that the EPB may have malfunc‐
tioned.
If this occurs, we recommend that the system be checked by an authorized
Kia dealer.
The EPB malfunction indicator may illu‐
minate when the ESC indicator comes on to indicate that the ESC is not work‐
ing properly, but it does not indicate a
malfunction of the EPB.
CAUTION
•The EPB warning light may illumi‐nate if the EPB switch operatesabnormally. Shut the engine offand turn it on again after a fewminutes. The warning light will gooff and the EPB switch will oper‐ate normally. However, if the EPBwarning light is still on, we recom‐mend that the system be checkedby an authorized Kia dealer.

During that time, theABS will go through self-diagnosisand the light will go off if every‐thing is normal. If the light stayson, you may have a problem withyour ABS. We recommend that youcontact an authorized Kia dealer.
CAUTION
•When you drive on a road havingpoor traction, such as an icy road,and operate your brakes continu‐ously, the ABS will be active con‐tinuously and the ABS warninglight may illuminate. Pull your ve‐hicle over to a safe place and stopthe engine.
•Restart the engine. If the ABSwarning light is off, then your ABSsystem is normal. Otherwise, youmay have a problem with the ABS.We recommend that you contactan authorized Kia dealer.
NOTICE
When you jump start your vehicle
because of a drained battery, the
engine may not run as smoothly and
the ABS warning light may turn on
at the same time. This happens be‐
cause of the low battery voltage. It
does not mean your ABS is malfunc‐
tioning.
•Do not pump your brakes!
•Have the battery recharged before
driving the vehicle.

system self-check and does not indicate a problem.
When operating
When the ESC is in operation, ESC indicator light blinks. • When the Electronic Stabili‐ ty Control is operating
properly, you can feel a
slight pulsation in the vehi‐
cle. This is only the effect of brake control and indi‐
cates nothing unusual.
• When moving out of the mud or slippery road, the
engine rpm (revolution per
minute) may not increase
even if you press the accel‐ erator pedal deeply. This is
to maintain the stability
and traction of the vehicle
and does not indicate a
problem.
