The speedometer indicates the
speed of the vehicle and is calibrated
in miles per hour (mph) and/or kilo-
meters per hour (km/h).
Engine coolant temperature gauge
This gauge shows the temperature
of the engine coolant when the
Engine Start/Stop button is in the ON
position.
Do not continue driving with an over-
heated engine. If your vehicle over-
heats, refer to “If the engine over-
heats” in chapter 7.
If the gauge pointer moves beyond
the normal range area toward the
“Red (H)” position, it indicates over-
heating that may damage the

Engine Coolant
Temperature WarningLight
This warning light illuminates:
When the engine coolant tempera- ture is above 248°F (120°C). This
means that the engine is overheat-
ed and may be damaged.
If your vehicle is overheated, refer
to “Overheating” in chapter 7.
Indicator Lights

Before entering vehicle
• Be sure that all windows, outsidemirror(s), and outside lights are
clean.
Check the condition of the tires.
Check under the vehicle for any sign of leaks.
Be sure there are no obstacles behind you if you intend to back up.
Necessary inspections
Fluid levels, such as engine oil,
engine coolant, brake fluid, and
washer fluid should be checked on a
regular basis, at the exact interval
depending on the fluid. Further
details are provided in chapter 8,
“Maintenance”.
Before starting
Close and lock all doors.
Position the seat so that all con-trols are easily reached.
Buckle your seat belt.
Adjust the inside and outside rearview mirrors.
Be sure that all lights work.
Check all gauges.
Check the operation of warning lights when the engine start/stop
button is turned to the ON position.
Release the parking brake and make sure the brake warning light
goes out.
For safe operation, be sure you are
familiar with your vehicle and its
equipment.
BEFORE DRIVING
WARNING - Distracted driving
Focus on the road while driving.
The driver's primary responsi-
bility is in the safe and legal
operation of the vehicle. Use of
any handled devices, other
equipment or vehicle systems
that distract the drive should
not be used during vehicle
operation.

When Active ECO is activated:
The acceleration may slightly be
reduced even though you depress
the accelerator fully.
The air conditioner performance may be limited
The shift pattern of the automatic transaxle may change.
The engine noise may get louder.
The above situations are normal
conditions when the Active Eco
System is activated to improve fuel
efficiency. Limitation of Active ECO opera-
tion:
If the following conditions occur while
Active ECO is operating, the system
operation is limited even though
there is no change in the ECO indi-
cator.
When the coolant temperature is
low:
The system will be limited until
engine performance becomes nor-
mal.
When driving up a hill: The system will be limited to gain
power when driving uphill because
the engine torque is restricted.
When using manual mode: The system will be limited accord-
ing to the shift location.
When the accelerator pedal is deeply depressed for a few sec-
onds:
The system will be limited, judging
that the driver wants to speed up.SPORT mode
SPORT mode focuses on
dynamic driving by auto-
matically adjusting the
steering wheel, engine
and transaxle system.
When the DRIVE MODE button is pressed and the SPORT mode is
selected, the SPORT indicator
(yellow) will illuminate.
Whenever the hybrid system is restarted, the Drive Mode will revert
back to ECO mode. If SPORT
mode is desired, re-select SPORT
mode from the DRIVE MODE but-
ton.
If the system is activated: - While holding vehicle speed, itmaintains the gear and RPM for
some time even though the accel-
erator pedal is not depressed.
- Up-shifting is delayed.

NOTICE
In Sport drive mode, the fuel effi-
ciency may decrease.

Driving in flooded areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel
hub. Drive through any water slowly.
Allow adequate stopping distance
because brake performance may be
affected.
After driving through water, dry the
brakes by gently applying them sev-
eral times while the vehicle is moving
slowly.
Driving off-road
Drive carefully off-road because your
vehicle may be damaged by rocks or
roots of trees. Become familiar with
the off-road conditions where you
are going to drive before you begin
driving.
Highway driving
Tires
Adjust the tire inflation pressures to
specification. Low tire inflation pres-
sures will result in overheating and
possible failure of the tires.
Avoid using worn or damaged tires
which may result in reduced traction
or tire failure.
Never exceed the maximum tire
inflation pressure shown on the tires.
Fuel, engine coolant and engine oil
High speed travel consumes more
fuel than urban motoring. Do not for-
get to check both the engine coolant
and engine oil.
Drive belt
A loose or damaged drive belt may
result in overheating of the engine.
WARNING- Under/over
inflated tires
Always check the tires for proper
inflation before driving.
Underinflated or overinflated
tires can cause poor handling,
loss of vehicle control, and sud-
den tire failure leading to acci-
dents, injuries, and even death.
For proper tire pressures, refer to
“Tires and wheels” in chapter 9.
WARNING- Tire tread
Always check the tire tread
before driving your vehicle.
Worn-out tires can result in loss
of vehicle control. Worn-out tires
should be replaced as soon as
possible. For further information
and tread limits, refer to "Tires
and wheels" in chapter 8.

To keep locks from freezing
To keep the locks from freezing,
squirt an approved de-icer fluid or
glycerine into the key opening. If a
lock is covered with ice, squirt it with
an approved de-icing fluid to remove
the ice. If the lock is frozen internally,
you may be able to thaw it out by
using a heated key. Handle the heat-
ed key with care to avoid injury.
Use approved window washer
anti-freeze in system
To keep the water in the window
washer system from freezing, add an
approved window washer anti-freeze
solution in accordance with instruc-
tions on the container. Window wash-
er anti-freeze is available from an
authorized Kia dealer and most auto
parts outlets. Do not use engine
coolant or other types of anti-freeze
as these may damage the paint fin-
ish.
Don’t let your parking brake
freeze
Under some conditions your parking
brake can freeze in the engaged
position. This is most likely to happen
when there is an accumulation of
snow or ice around or near the rear
brakes or if the brakes are wet. If
there is a risk the parking brake may
freeze, apply it only temporarily while
you put the gear shift lever in P (Park,
Automatic Transaxle) and block the
rear wheels so the vehicle cannot roll.
Then release the parking brake.
Don't let ice and snow accu-
mulate underneath
Under some conditions, snow and
ice can build up under the fenders
and interfere with the steering. When
driving in severe winter conditions
where this may happen, you should
periodically check underneath the
vehicle to be sure the movement of
the front wheels and the steering
components are not obstructed.
Carry emergency equipment
Depending on the severity of the
weather, you should carry appropri-
ate emergency equipment. Some of
the items you may want to carry
include tow straps or chains, flash-
light, emergency flares, sand, shov-
el, jumper cables, window scraper,
gloves, ground cloth, coveralls, blan-
ket, etc.
TRAILER TOWING
We do not recommend using this
vehicle for trailer towing.
