Driving your vehicle
Prerequisite for activation
The FCA gets ready to be activated,
when the FCA is selected on the
LCD display, and when the following
prerequisites are satisfied.
- The ESC (Electronic StabilityControl) is activated.
- Vehicle speed is over 5 mph (8 km/h). (The FCA is only activated
within a certain speed range.)
- The system detects a vehicle or pedestrian in front, which may col-
lide with your vehicle. (The FCA
may not be activated or may sound
a warning alarm in accordance
with the driving situation or vehicle
condition.)
❈ The FCA may not operate properly
according to the frontal situation,
the direction and speed of pedes-
trian.
FCA warning message and
system control
The FCA system produces warning
messages, warning alarms, and
emergency braking based on the
level of risk of a frontal collision, such
as when a vehicle ahead suddenly
brakes.
The driver can select the initial warn-
ing activation time in the User
Settings in the LCD display. The
options for the initial Forward
Collision Warning include Early,
Normal or Late initial warning time.
WARNING
Completely stop the vehicle
on a safe location before
operating the switch on the
steering wheel to activate/
deactivate the FCA system.
The FCA automatically acti- vates upon placing the Engine
Start/Stop button to the ON
position. The driver can deac-
tivate the FCA by canceling
the system setting on the LCD
display. To avoid driver dis-
tractions, do not attempt to
set or cancel the FCA while
driving the vehicle.
The FCA automatically deac- tivates upon canceling the
ESC (Electronic Stability
Control). When the ESC is
canceled, the FCA cannot be
activated on the LCD display.
The FCA warning light will
illuminate, but it does not
indicate a malfunction of the
system.

Collision Warning (1st warning)
This warning message appears on
the LCD display with a warning
chime. Additionally, some vehicle
system intervention occurs by the
engine management system to help
decelerate the vehicle.
- Your vehicle speed may decelerate
moderately.
- The FCA system limitedly controls the brakes to preemptively mitigate
impact in a collision. - It will operate if the vehicle speed is
greater than 5 mph (8 km/h) and
less than or equal to 50 mph (80
km/h) on a forward vehicle.
(Depending on the condition of the
vehicle ahead and the environment
surrounding it, the possible maxi-
mum operating speed may be
reduced.)
Emergency braking (2nd warning)
This warning message appears on
the LCD display with a warning
chime. Additionally, some vehicle
system intervention occurs by the
engine management system to help
decelerate the vehicle.
- The FCA system limitedly controlsthe brakes to preemptively mitigate
impact in a collision. The brake
control is maximized just before a
collision.

Driving your vehicle
- It will operate if the vehicle speed isgreater than 5 mph (8 km/h) and
less than or equal to 110 mph (180
km/h) on a forward vehicle.
(Depending on the condition of the
vehicle ahead and the environment
surrounding it, the possible maxi-
mum operating speed may be
reduced.)Brake operation
In an urgent situation, the FCAsystem applies the brakes.
The FCA provides additional brak- ing power for optimum braking per-
formance, when the driver
depresses the brake pedal.
The braking control is automatical- ly deactivated, when the driver
sharply depresses the accelerator
pedal, or when the driver abruptly
operates the steering wheel.
The FCA brake control is automat- ically canceled, when risk factors
disappear.
CAUTION
The driver should always paygreat caution to vehicle opera-tion, even though there is nowarning message or warningalarm. The warning of the FCAsystem may not sound whileother system warning sounds.
WARNING
The FCA system logic assesses
the risk of a collision by moni-
toring several variables, such
as the distance from the vehicle
ahead, the speed of the vehicle
ahead, and the driver's vehicle
speed. Certain conditions, such
as inclement weather and road
conditions, may affect the oper-
ation of the FCA system.
WARNING
Never deliberately drive danger-
ously to activate the system.
WARNING
The FCA cannot avoid all colli-
sions. The braking control can-
not completely stop the vehicle.
The driver is responsible to
safely drive and control the
vehicle.

CRUISE CONTROL SYSTEM
The cruise control system allows you
to program the vehicle to maintain a
constant speed without depressing
the accelerator pedal.
This system is designed to function
above approximately 20 mph (30
km/h).
If the cruise control is left on,
(CRUISE indicator light in the instru-
ment cluster illuminated) the cruise
control can be switched on acciden-
tally. Keep the cruise control system
off (CRUISE indicator light OFF)
when the cruise control is not in use,
to avoid inadvertently setting a speed. Use the cruise control system only
when traveling on open highways in
good weather.
Do not use the cruise control when
driving in heavy or varying traffic, or
on slippery (rainy, icy or snow-cov-
ered) or winding roads or over 6%
up-hill or down-hill roads.
✽ ✽
NOTICE
• During normal cruise control oper-
ation, when the SET switch is acti-
vated or reactivated after applying
the brakes, the cruise control will
activate after approximately 3 sec-
onds. This delay is normal.
• To activate cruise control, depress the brake pedal at least once after
turning the ignition switch to the
ON position or starting the engine.
WARNING - Misuse of
Cruise Control
Do not use cruise control if the
traffic situation does not allow
you to drive safely at a constant
speed and with sufficient dis-
tance to the vehicle in front.

WARNING
When using the Smart Cruise
Control take the following pre-
cautions:
If an emergency stop is nec-
essary, you must apply the
brakes. The vehicle cannot be
stopped at every emergency
situation by using the Smart
Cruise Control system.
Keep a safe distance accord- ing to road conditions and
vehicle speed. If the vehicle to
vehicle distance is too close a
serious collision may result.
Always maintain sufficient braking distance and deceler-
ate your vehicle by applying
the brakes if necessary.
The Smart Cruise Control sys- tem cannot recognize a
stopped vehicle, pedestrians
or an oncoming vehicle.
(Continued)
(Continued)Always look ahead to prevent
unexpected and sudden situa-
tions from occurring.
Vehicles moving in front of you with a frequent lane
change may cause a delay in
the system's reaction or may
cause the system to react to a
vehicle actually in an adjacent
lane.
Always drive cautiously to
pre-vent unexpected and sud-
den situations from occur-
ring.
Always be aware of the select- ed speed and vehicle to vehi-
cle distance. The driver
should not solely rely on the
system but always pay atten-
tion to driving conditions and
control your vehicle speed.
(Continued)(Continued)
The Smart Cruise Control sys-tem may not recognize com-
plex driving situations so
always pay attention to driv-
ing conditions and control
your vehicle speed.
For safe operation, carefully read and follow the instruc-
tions in this manual before
use.

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 miles (kilometers) you can get
from a gallon (liter) of fuel. To operate
your vehicle as economically as pos-
sible, use the following driving sug-
gestions to help save money in both
fuel and repairs:
Drive smoothly. Accelerate at a
moderate rate. Don't make "jack-
rabbit" starts or full-throttle shifts
and maintain a steady cruising
speed. Don't race between stop-
lights. Try to adjust your speed to
the traffic so you don't have to
change speeds unnecessarily.
Avoid heavy traffic whenever pos- sible. Always maintain a safe dis-
tance from other vehicles so you
can avoid unnecessary braking.
This also reduces brake wear.
Drive at a moderate speed. The faster you drive, the more fuel your
vehicle uses. Driving at a moderate
speed, especially on the highway,
is one of the most effective ways to
reduce fuel consumption. Don't "ride" the brake pedal. 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 con-
sequences.
Take care of your tires. Keep them inflated to the recommended pres-
sure. Incorrect inflation, either too
much or too little, results in unnec-
essary tire wear. Check the tire
pressures at least once a month.
Be sure that the wheels are aligned correctly. Improper align-
ment can result from hitting curbs
or driving too fast over irregular
surfaces. Poor alignment causes
faster tire wear and may also result
in other problems as well as
greater fuel consumption. Keep your vehicle in good condi-
tion. For better fuel economy and
reduced maintenance costs, main-
tain your vehicle in accordance
with the maintenance schedule in
chapter 8. If you drive your vehicle
in severe conditions, more frequent
maintenance is required (see
chapter 8 for details).
Keep your vehicle clean. For maxi- mum service, your vehicle should
be kept clean and free of corrosive
materials. 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 also contribute to
corrosion.
Travel lightly. Don't carry unneces- sary weight in your vehicle. Weight
reduces fuel economy.
Don't let the engine idle longer than necessary. If you are waiting
(and not in traffic), turn off your
engine and restart only when
you're ready to go.
ECONOMICAL OPERATION

5131
Driving your vehicle
Remember, your vehicle does notrequire 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 warm-
up period.
Don't "lug" or "over-rev" the engine. Lugging is driving too slowly in a
very high gear resulting in engine
bucking. If this happens, shift to a
lower gear. Over-revving is racing
the engine beyond its safe limit.
This can be avoided by shifting at
the recommended speed. Use your air conditioning sparingly.
The air conditioning system is
operated by engine power so your
fuel economy is reduced when you
use it.
Opening windows at high speeds can reduce fuel economy.
Fuel economy is less in crosswinds and headwinds. To help offset
some of this loss, slow down when
driving in these conditions.
Keeping a vehicle in good operating
condition is important both for econ-
omy and safety. Therefore, have an
authorized Kia dealer perform
scheduled inspections and mainte-
nance.
WARNING - Engine off during motion
Never turn the engine off to
coast down hills or anytime the
vehicle is in motion. The power
steering and power brakes will
not function properly without
the engine running. In addition,
turning off the engine start/stop
button while driving could
engage the steering wheel lock
resulting in loss of vehicle
steering. Keep the engine on
and downshift to an appropriate
gear for an engine braking
effect.

Hazardous driving conditions
When hazardous driving conditions
are encountered such as water,
snow, ice, mud, sand, or similar haz-
ards, follow these suggestions:
Drive cautiously and allow extra
distance 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.
Do not pump the brake pedal on a
vehicle equipped with ABS. If stalled in snow, mud, or sand,
use the second gear. Accelerate
slowly to avoid spinning the drive
wheels.
Use sand, rock salt, or other non- slip material under the drive
wheels to provide traction when
stalled in ice, snow, or mud.
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 between R (Reverse) and any
forward gear in vehicles equipped
with an Automatic 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 possi-
ble damage to the transmission.
SPECIAL DRIVING CONDITIONS
WARNING- Downshifting
Do not downshift with an auto-
matic transmission while driv-
ing on slippery surfaces. The
sudden change in tire speed
could cause the tires to skid
and result in an accident.
WARNING- Sudden
Vehicle Movement
Do not attempt to rock the vehi-
cle if people or objects are near-
by. The vehicle may suddenly
move forward or backwards as it
becomes unstuck.

Adjust your mirrors to reduce the
glare from other driver's head-
lights.
Keep your headlights clean and properly aimed. (On vehicles not
equipped with the automatic head-
light aiming feature.) Dirty or
improperly aimed headlights will
make it much more difficult to see
at night.
Avoid staring directly at the head- lights of oncoming vehicles. You
could be temporarily blinded, and it
will take several seconds for your
eyes to readjust to the darkness.Driving in the rain
Rain and wet roads can make driving
dangerous, especially if you’re not
prepared for the slick pavement.
Here are a few things to consider
when driving in the rain: A heavy rainfall will make it harder
to see and will increase the dis-
tance needed to stop your vehicle,
so slow down.
Keep your windshield wiping equipment in good shape. Replace
your windshield wiper blades when
they show signs of streaking or
missing areas on the windshield.
If your tires are not in good condi- tion, making a quick stop on wet
pavement can cause a skid and
possibly lead to an accident. Be
sure your tires are in good shape.
Turn on your headlights to make it easier for others to see you.
Driving too fast through large pud- dles can affect your brakes. If you
must go through puddles, try to
drive through them slowly.
If you believe you may have gotten your brakes wet, apply them lightly
while driving until normal braking
operation returns.
