Warning message
When the sensor lens cover is
blocked with dirt, snow, or debris,
Smart Cruise Control operation may
stop temporarily. If this occurs, a
warning message will appear on the
LCD display. Remove any dirt, snow,
or debris and clean the radar sensor
lens cover before operating Smart
Cruise Control. Smart Cruise Control
may not properly activate, if the radar
is totally contaminated, or if any sub-
stance is detected after turning ON
the engine (e.g. in an open terrain).
Smart Cruise Control malfunction
message
The message will appear when the
vehicle distance control function is
not functioning normally.
Take your vehicle to an authorized
Kia dealer and have the system
checked.

CAUTION
Do not install accessories
around the sensor and do not
replace the bumper by your-
self. It may interfere with the
sensor performance.
Always keep the sensor and
bumper clean.
Use only a soft cloth to wash
the vehicle. Do not spray pres-
surized water directly on the
sensor or sensor cover.
Be careful not to apply unnec-
essary force on the radar sen-
sor or sensor cover. If the sen-
sor is forcibly moved out of
proper alignment, Smart
Cruise Control may not oper-
ate correctly. In this case, a
warning message may not be
displayed.
Have the system checked by
an authorized Kia dealer.

LFA operation
To use Lane Following Assist two
steps are necessary:
(1) LFA has to be enabled, and
(2) SCC has to be activated
With the ignition switch or ENGINE
START/STOP button in the [ON],
select or release the setting from
“User setting Driver Assistance 
Driving Assist Lane Following
Assist”.
Select LFA in the user setting of the
instrument panel.
LFA status is remembered by the
function and therefore does not need
to be enabled again for each new
journey.
(Continued)
- Depending on your surround-
ings and road conditions, LFA
could fail to recognize the
lane and stop working. In turn,
extra caution is required
while driving with LFA on.
- Be sure to check the non-
operating conditions and cau-
tions for the driver before
using LFA.
- Do not place reflective materi-
als such as white paper or
mirror on the crash pad.
Sunlight reflections can cause
a malfunction in LFA.
- Too big sound from the sound
function can interrupt the
alarming sound from LFA.
(Continued)(Continued)
- Keeping your hands off the
wheel while driving will trigger
the hands-off warning and
deactivate the steering-assist
function. Put your hands back
on the wheel, then the steer-
ing-assist system will be re-
activated.
- When driving at a high speed,
the steering assist force can
become weak and the vehicle
can drive out of its lane. Extra
caution is required, and com-
ply with the speed limit.
- Attaching an object to the
steering wheel could deter
steering assistance.
- Attaching an object to the
steering wheel could deter the
hands-off alarming system.

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.

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.
