The Virtual Engine Sound System gen‐
erates an engine sound for pedestrians to hear vehicle while at low speeds in
EV mode.
High voltage battery air intake
Hybrid battery air intake
The hybrid battery air intake is located
on the bottom of the rear seats. The air intake cools down the hybrid bat‐
tery. When the hybrid battery air in‐
take is blocked, the hybrid battery may be overheated. Do not obstruct the air
intake with any other objects.

The high-voltage battery air intake is
located on the left side of the rear seats. The air intake cools down the
high-voltage battery.
When the high-voltage battery air in‐
take is blocked, the high-voltage bat‐ tery may be overheated and the vehicle
performance may become limited and
set a hybrid warning lamp. Do not ob‐ struct the air intake with any other ob‐
jects.
WARNING
nAir Intake
•Blocking the air intake behind therear seats may damage the HEVbattery.
•Do not allow any water into the airintake even when cleaning. If anywater enters the air intake, theHybrid battery may cause an elec‐tric shock which can cause seriousinjury or death due to electrocu‐tion.
If an accident occurs
• Avoid the engine compartment.
• Avoid any orange or high voltage wires, cables, or components.
• Assume that a high voltage compo‐ nent is exposed and move away fromthe vehicle as promptly as possible.
• Refer to 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.

•For your safety, depress the brake
pedal and release the parking
brake manually with the EPB
switch when you drive downhill or
when backing up the vehicle.
CAUTION
•If the parking brake warning lightis still on even though the EPB hasbeen released, we recommendthat the system be checked by anauthorized Kia dealer.
•Do not drive your vehicle with theEPB applied. It may cause exces‐sive brake pad and brake rotorwear.
EPB (Electronic Parking Brake) may beautomatically applied when:
• The EPB is overheated
• Requested by other systems
• The hybrid system is turned off with the EPB applied
NOTICE
If the driver turns the hybrid system
off while Auto Hold is operating, EPB
will be automatically applied. Howev‐
er, if you press the EPB switch with‐
in one second after the hybrid sys‐
tem is turned off, the EPB will not
be applied.
System warning
0+'-
• If you try to drive off depressing theaccelerator pedal with the EPB ap‐
plied, but doesn't release automati‐ cally, a warning will sound and a mes‐
sage will appear.
• If the driver's seat belt is not fas‐ tened and the engine hood or trunk is
opened, a warning will sound and a
message will appear.
• If there is a problem with the vehicle, a warning may sound and a message
may appear.
If the above situation occurs, depress
the brake pedal and release EPB by pressing the EPB switch.
WARNING
•To prevent unintentional move‐ment when stopped and leavingthe vehicle, do not use the shiftlever in place of the parking brake.Set the parking brake and makesure the shift lever is securelypositioned in P (Park).

ECONOMICAL OPERATION
Your vehicle's fuel economy depends mainly on your style of driving, where
you drive and when you drive.
Each of these factors affects how
many kilometers (miles) you can get from a liter (gallon) of fuel. To operate
your vehicle as economically as possi‐
ble, use the following driving sugges‐ tions to help save money in both fuel
and repairs: • Drive smoothly. Accelerate at a mod‐ erate rate. Do not make "jack-rabbit"
starts or full-throttle shifts and maintain a steady cruising speed. Do
not race between stop lights. Try to
adjust your speed to the traffic so
you do not have to change speeds
unnecessarily. Avoid heavy traffic whenever possible.
Always maintain a safe distance from
other vehicles so you can avoid un‐
necessary braking. This also reduces
brake wear.
• Drive at a moderate speed. The fast‐ er you drive, the more fuel your vehi‐cle uses. Driving at a moderate
speed, especially on the highway, is
one of the most effective ways to re‐
duce fuel consumption. • Do not "ride" the brake or clutch ped‐
al. This can increase fuel consumption
and also increase wear on these com‐
ponents. In addition, driving with your
foot resting on the brake pedal may
cause the brakes to overheat, which
reduces their effectiveness and may lead to more serious consequences.
• Take care of your tires. Keep them inflated to the recommended pres‐
sure. Incorrect inflation, either too
much or too little, results in unneces‐
sary tire wear. Check the tire pres‐ sures at least once a month.
• Be sure that the wheels are aligned correctly. Improper alignment can re‐
sult from hitting curbs or driving too
fast over irregular surfaces. Poor alignment causes faster tire wear
and may also result in other prob‐
lems as well as greater fuel con‐
sumption.
• Keep your vehicle in good condition. For better fuel economy and reducedmaintenance costs, maintain your ve‐
hicle in accordance with the mainte‐
nance schedule in Chapter 9, Mainte‐
nance. If you drive your vehicle in se‐
vere conditions, more frequent main‐ tenance is required (see Chapter 9,
Maintenance for details). • Keep your vehicle clean. For maxi‐
mum service, your vehicle should be
kept clean and free of corrosive ma‐ terials. It is especially important that
mud, dirt, ice, etc. not be allowed to
accumulate on the underside of the
vehicle. This extra weight can result
in increased fuel consumption and al‐ so contribute to corrosion.
• Travel lightly. Do not carry unneces‐ sary weight in your vehicle. Weight
reduces fuel economy.
• Do not let the engine idle longer than necessary. If you are waiting (and notin traffic), turn off your engine and
restart only when you're ready to go.
• Remember, your vehicle does not re‐ quire extended warm-up. After the
engine has started, allow the engine
to run for 10 to 20 seconds prior to placing the vehicle in gear. In very cold
weather, however, give your engine a
slightly longer warmup period.
• Do not "lug" or "over-rev" the engine. Lugging is driving too slowly in too
high a gear resulting engine bucking.
If this happens, shift to a lower gear. Over-revving is racing the engine be‐
yond its safe limit. This can be avoi‐
ded by shifting at the recommended
speeds.

SPECIAL DRIVING CONDITIONS
Hazardous driving conditions
When hazardous driving conditions are
encountered such as water, snow, ice, mud, sand, or similar hazards, follow
these suggestions: • Drive cautiously and allow extra dis‐ tance for braking.
• Avoid sudden braking or steering.
• When braking with non-ABS brakes pump the brake pedal with a light up-
and-down motion until the vehicle is stopped.
WARNING
nABS
Do not pump the brake pedal on avehicle equipped with ABS.
• If stalled in snow, mud, or sand, use second gear. Accelerate slowly to
avoid spinning the drive wheels.
• Use sand, rock salt, tire chains, or other non-slip material under the
drive wheels to provide traction when
stalled in ice, snow, or mud.
WARNING
nDownshifting
Downshifting with an automatictransaxle, while driving on slipperysurfaces can cause an accident. Thesudden change in tire speed couldcause the tires to skid. Be carefulwhen downshifting on slippery sur‐faces.
Rocking the vehicle
If it is necessary to rock the vehicle to
free it from snow, sand, or mud, first turn the steering wheel right and left
to clear the area around your front
wheels. Then, shift back and forth be‐ tween 1 (First) and R (Reverse) in vehi‐
cles equipped with a manual transaxle
or R (Reverse) and any forward gear in vehicles equipped with an Automatic
Transaxle / Dual clutch transmission. Do
not race the engine, and spin the wheels as little as possible. If you are
still stuck after a few tries, have the
vehicle pulled out by a tow vehicle to
avoid engine overheating and possible
damage to the transaxle.
CAUTION
Prolonged rocking may cause engineover-heating, transaxle damage orfailure, and tire damage.
WARNING
nSpinning tires
Do not spin the wheels, especially atspeeds more than 56 km/h(35 mph). Spinning the wheels athigh speeds when the vehicle is sta‐tionary could cause a tire to over‐heat which could result in tire dam‐age that may injure bystanders.
NOTICE
The ESC system should be turned
OFF prior to rocking the vehicle.

Jump starting procedure
1. Make sure the booster battery is12-volt and that its negative termi‐ nal is grounded.
2. If the booster battery is in another vehicle, do not allow the vehicles
come in contact.
3. Turn off all unnecessary electrical loads.
4. Connect the jumper cables in the exact sequence shown in the illus‐
tration. First connect one end of a
jumper cable to the positive termi‐
nal of the discharged battery (1),
then connect the other end to the
positive terminal on the booster
battery (2).
Proceed to connect one end of the other jumper cable to the negative
terminal of the booster battery (3),
then the other end to a solid, sta‐
tionary, metallic point (for example,
the engine lifting bracket) away
from the battery (4). Do not con‐
nect it to or near any part that
moves when the engine is cranked.
Do not allow the jumper cables to
contact anything except the correct
battery terminals or the correct
ground. Do not lean over the bat‐ tery when making connections.CAUTION
nBattery cables
Do not connect the jumper cablefrom the negative terminal of thebooster battery to the negative ter‐minal of the discharged battery. Thiscan cause the discharged battery tooverheat and crack, releasing bat‐tery acid.
5. Start the engine of the vehicle with the booster battery and let it run
at 2,000 rpm, then start the engine
of the vehicle with the discharged
battery.
If the cause of your battery discharging is not apparent, we recommend that
the system be checked by an author‐
ized Kia dealer.
Push-starting
Your manual transaxle-equipped vehi‐
cle should not be push-started because it might damage the emission control
system.
Vehicles equipped with automatic
transaxle cannot be push-started.
Follow the directions in L

IF THE ENGINE OVERHEATS
If your temperature gauge indicates
overheating, you will experience a loss of power, or hear loud pinging or knock‐
ing, the engine is probably too hot. If
this happens, you should: 1. Turn on the emergency warning flasher 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, carefullyopen the engine room and check
whether the water pump connector
is properly engaged. If the connec‐
tor is not properly engaged, stop
the engine immediately and prop‐
erly engage the connector. Then,
turn the engine on.
3. Turn on the air conditioner.
4. If the L
