Each of these actions will cancel
cruise control operation (the SET
indicator light in the instrument clus-
ter will go off), but it will not turn the
system off. If you wish to resume
cruise control operation, move the
lever up (to RES+). You will return to
your previously preset speed.

To resume cruising speed at
more than approximately 20
mph (30 km/h):

If any method other than the
CRUISE ON-OFF switch was used
to cancel cruising speed and the sys-
tem is still activated, the most recent
set speed will automatically resume
when you move the lever up.
It will not resume, however, if the
vehicle speed has dropped below
approximately 20 mph (30 km/h).

To turn cruise control off, do
one of the following:

• Press the CRUISE button (the

CRUISE indicator light in the
instrument cluster will go off).

• Turn the ignition off.
Both of these actions will cancel the
cruise control operation. If you want
to resume the cruise control opera-
tion, repeat the steps provided in “To
set cruise control speed” on the pre-
vious page.

WARNING

- Advanced

Smart Cruise Control
Limitations

• The advanced smart cruise

control is a supplemental sys-
tem and is not a substitute for
safe driving practices. It is the
responsibility of the driver to
always check the speed and
distance to the vehicle ahead.

• Do not use the advanced

smart cruise control when it
may not be safe to keep the
car at a constant speed, for
instance, driving in heavy or
varying traffic, or on slippery
(rainy, icy or snow-covered) or
winding roads or over 6%
uphill or down-hill roads.

Radar to detect distance to the
vehicle ahead

The sensor detects distance to the
vehicle ahead.
If the sensor is covered with dirt or
other foreign matter, the vehicle to
vehicle distance control may not
operate correctly.
Always keep the sensor clean.

Radar check message

If the radar or cover is dirty or
obscured with foreign matter such as
snow, this message will appear and it
will disappear after for a while. In this
case, the system may not function
temporarily, but it does not indicate a
malfunction of the Advanced Smart
Cruise Control System. Clean the
radar or cover by using a soft cloth
and it will operate normally.

ASCC (Advanced Smart Cruise
Control) malfunction message

The message will appear when the
vehicle to vehicle distance control
system is not functioning normally.

• Always keep the sensor and

bumper clean.

• Use only a genuine Kia sensor

cover for your vehicle.

• Do not install accessories around

the sensor and do not replace the
bumper by yourself. It may interfere
with the sensor performance.

• Impact damage to the sensor or

sensor area may cause the sensor
to move slightly off position and
result in the ASCC not operating
correctly without any warning or
indicator from the cluster. If this
occurs, have your vehicle checked
by an authorized Kia dealer as
soon as possible.

To adjust the sensitivity of
Advanced Smart Cruise Control

The sensitivity of vehicle speed when
following the front vehicle to maintain
the set distance can be adjusted. Go
to the User Settings Mode (Driving
Assist) and select SCC (Smart
Cruise Control). You may select one
of the three stages you prefer.
• Slow:

Vehicle speed following the front
vehicle to maintain the set distance
is slower than normal speed.

• Normal:

Vehicle speed following the front
vehicle to maintain the set distance
is normal

• Fast:

Vehicle speed following the front
vehicle to maintain the set distance
is faster than normal speed.

✽

To convert to cruise control
mode:

The driver may choose to only use
the cruise control mode (speed con-
trol function) by doing as follows:

1.Turn the ASCC on (the cruise indi-

cator light will be on but the system
will not be activated).

2.Push the distance to distance

switch for more than 2 seconds.

3.Choose between "Smart cruise

control (SCC) mode" and "Cruise
control (CC) mode".

4.Speed setting is equal to the

advanced smart cruise control
operation method. However, when
it is turned off by the CRUISE
switch or the CRUISE switch is
operated after the engine is
restarted, it automatically returns
to the advanced smart cruise con-
trol system.

When using the cruise control mode,
you must manually assess the dis-
tance to other vehicles as the system
will not automatically brake to slow
down for other vehicles.

Limitations of the system

The ASCC may have limits to its abil-
ity to detect distance to the vehicle
ahead due to road and traffic condi-
tions.

On curves

• On curves, the ASCC may not

detect a moving vehicle in your
lane, and then your vehicle could
accelerate to the set speed. Also,
the vehicle speed will rapidly slow
down when the vehicle ahead is
recognized suddenly.

• Select the appropriate set speed

on curves and adjust your vehicle
speed by depressing the accelera-
tor or brake pedal according to the
road condition ahead and driving
condition.

• Your vehicle speed can be reduced

due to a vehicle in the adjacent
lane. Adjust your vehicle speed by
depressing the brake pedal
according to the road condition
ahead and driving condition. Apply
the accelerator pedal and select
the appropriate set speed. Check
to be sure that the road conditions
permit safe operation of the ASCC.

On inclines

• During uphill or downhill driving, the

ASCC may not detect a moving
vehicle in your lane, and cause
your vehicle to accelerate to the set
speed. Also, the vehicle speed will
rapidly slow down when the vehicle
ahead is recognized suddenly.

• Select the appropriate set speed

on inclines and adjust your vehicle
speed by depressing the accelera-
tor or brake pedal according to the
road condition ahead.

Lane changing

• A vehicle which moves into your

lane from an adjacent lane cannot
be recognized by the sensor until it
is in the sensor's detection range.

• The sensor may not detect imme-

diately when a vehicle cuts in sud-
denly. Always pay attention to the
traffic, road and driving conditions.

• If a vehicle which moves into your

lane is slower than your vehicle,
your speed may decrease to main-
tain the distance to the vehicle
ahead.

• If a vehicle which moves into your

lane is faster than your vehicle,
your vehicle will accelerate to the
selected speed.

• Your vehicle may accelerate when

a vehicle ahead of you disappears.

• When you are warned that the

vehicle ahead of you is not detect-
ed, drive with caution.

Vehicle recognition

Some vehicles ahead in your lane
cannot be recognized by the sensor
as follows:
- Narrow vehicles such as motorcy-

cles or bicycles

- Vehicles offset to one side
- Slow-moving vehicles or sudden-

decelerating vehicles

- Stopped vehicles
- Vehicles with small rear profile such

as trailers with no loads

A vehicle ahead cannot be recog-
nized correctly by the sensor if any of
following occurs:
-

When the vehicle is pointing

upwards due to overloading in the
trunk

- While making turns by steering
- When driving to one side of the lane
- When driving on narrow lanes or on

curves

Adjust your vehicle speed by
depressing the brake pedal accord-
ing to the road condition ahead and
driving condition.

• When vehicles are at a standstill

and the vehicle in front of you
changes to the next lane, be care-
ful when your vehicle starts to
move because it may not recog-
nize the stopped vehicle in front of
you.
