To resume Smart Cruise Control set
speed
If any method other than the cruise
switch was used to cancel cruising speed
and the system is still activated, the
cruising speed will automatically resume
when you push the SET+ switch up or
SET- switch down.
If you push the SET+ switch up, the
speed will resume to the recently set
speed. However, if vehicle speed drops
below 5 mph (10 km/h), it will resume
when there is a vehicle in front of your
vehicle.
Information
Always check the road conditions when
you push the SET+ switch up to resume
speed.
To turn Cruise Control off

speed.
• Use Smart Cruise Control system only
when traveling on open highways in
good weather.

While Driving
6-94
• Do not use Smart Cruise Control
when it may not be safe to keep the
vehicle at a constant speed:
-When driving in heavy traffic or
when traffic conditions make it
difficult to drive at a constant
speed
-When driving on rainy, icy, or
snow-covered roads
-When driving on a steep downhill
or uphill
-When driving in windy areas
-When driving in parking lots
-When driving near crash barriers
-When driving on a sharp curve
-When driving with limited view
(possibly due to bad weather, such
as fog, snow, rain or sandstorm)
-When the vehicle sensing
ability decreases due to vehicle
modification resulting level
difference of the vehicle’s front
and rear
• Unexpected situations may lead to
possible accidents. Pay attention
continuously to road conditions and
driving even when Smart Cruise
Control system is being operated. When changing the Drive mode setting,
the responsiveness of Smart Cruise
Control changes. (If equipped)

Smart Cruise Control Headway
To set Headway
ODN8069049
When Smart Cruise Control system
is ON, you can set and maintain the
distance from the vehicle ahead of you
without pressing the accelerator or brake
pedal.
Each time the button is pressed, the
Headway changes as follows:
Distance 4 Distance 3Distance 1Distance 2
For example, if you drive at 56 mph (90 km/h), the distance is maintained as
follows:
Distance 4 - approximately 172 feet
Distance 3 - approximately 130 feet
Distance 2 - approximately 160 feet
Distance 1 - approximately 82 feet
When the lane ahead is clear:
ODN8A069050
The vehicle speed will maintain the set
speed.

While Driving
6-96
When there is a vehicle ahead of you
in your lane:
Distance 4Distance 3ODN8A069051ODN8A069053
Distance 2Distance 1ODN8A069052ODN8A069054
Your vehicle speed will slow down or
speed up to maintain the selected
distance.
If the vehicle ahead speeds up, your
vehicle will travel at a steady cruising
speed after accelerating to the set speed.
If distance from the front vehicle has
been changed due to accelerating or
decelerating of the front vehicle, the
distance on the LCD display may change.
WARNING
ODN8H069205L
When using Smart Cruise Control
system:
• The warning message appears and
warning chime sounds if the vehicle
is unable to maintain the selected
distance from the vehicle ahead.
• If the warning message appears and
warning chime sounds, depress the
brake pedal to actively adjust the
vehicle speed, and the distance to
the vehicle ahead.
• Even if the warning message does
not appear and warning chime does
not sound, always pay attention to
the driving conditions to prevent
dangerous situations from occurring.
• Playing the vehicle audio system at
high volume may prevent occupants
from hearing the system warning
sounds.

CAUTION
ODN8A069212
If the vehicle ahead (vehicle speed:
less than 20 mph (30 km/h)) disappears
to the next lane, the warning chime
will sound and a message "Watch for
surrounding vehicles" will appear.
Adjust your vehicle speed for vehicles
or objects that can suddenly appear in
front of you by depressing the brake
pedal.
Always pay attention to the road
condition ahead.
In traffic situation
OOSH069118L
Use switch or pedal to accelerate
• In traffic, your vehicle will stop if the
vehicle ahead of you stops. Also,
if the vehicle ahead of you starts
moving, your vehicle will start as well.
However, if the vehicle stops for more
than 3 seconds, you must depress the
accelerator pedal or push up the RES+
switch to start driving.
• If you push Smart Cruise Control RES+
or SET- switch while Auto Hold and
smart cruise control is operating the
Auto Hold will be released regardless
of accelerator pedal operation and the
vehicle will start to move. The AUTO
HOLD indicator changes from green
to white.

Sensor to detect distance to the
vehicle ahead (Front view camera
and Front radar)
„„Front view camera
ODN8H060024N
Front view camera
The front view camera is a sensor
detecting the lane. If the sensors are
covered with snow, rain or foreign
substance, the system may temporarily
be cancelled and not work properly
until the system is cancelled due to the
degradation of the sensor’s detection
performance. Always keep the sensor
clean.
ÃRefer to “Lane Keeping Assist (LKA)”
for cautions for the front camera.
„„Front radar
ODN8H060023N
Front radar
The front radar is a sensor detecting
vehicles in front and maintains the
distance between them. If the sensors are covered with snow, rain
or foreign substance, the system may
temporarily be cancelled and not work
properly until the system is cancelled
due to the degradation of the sensor’s
detection performance. Always keep the
sensor clean.
CAUTION
•
Do not apply license plate frame or
foreign objects such as a bumper
sticker or a bumper guard near the
radar sensor. Doing so may adversely
affect the sensing performance of
the radar.
• Always keep the radar sensor and
lens cover clean and free of dirt and
debris.
• Use only a soft cloth to wash the
vehicle. Do not spray pressurized
water directly on the sensor or
sensor cover.
• Be careful not to apply unnecessary
force on the radar sensor or sensor
cover. If the sensor is forcibly
moved out of proper alignment,
Smart Cruise Control system
may not operate correctly. In this
case, a warning message may not
be displayed. Have the vehicle
inspected by an authorized HYUNDAI
dealer.
• If the front bumper becomes
damaged in the area around the
radar sensor, Smart Cruise Control
system may not operate properly.
Have the vehicle inspected by an
authorized HYUNDAI dealer.
• Use only genuine HYUNDAI parts to
repair or replace a damaged sensor
or sensor cover. Do not apply paint to
the sensor cover.

Warning message
OTM058061L
Smart Cruise Control disabled.
Radar blocked
When the sensor lens cover is blocked
with dirt, snow, or debris, Smart Cruise
Control system operation may stop
temporarily. If this occurs, a warning
message will appear on the cluster LCD
display. Remove any dirt, snow, or debris
and clean the radar sensor lens cover
before operating Smart Cruise Control
system. Smart Cruise Control system
may not properly activate, if the radar
is totally covered, or if any substance is
not detected after turning on the engine
(e.g. in an open terrain).
Information
For the SCC operation is temporarily
stopped if the radar is blocked, but you
wish to use cruise control mode (speed
control function), you must convert to the
cruise control mode (refer to "To convert
to Cruise Control mode" in the following
page.
OIK057109L
Check Smart Cruise Control System
The message will appear when Smart
Cruise Control system is not functioning
normally.
Have the vehicle inspected by an
authorized HYUNDAI dealer.

While Driving

Limitations of the System
Smart Cruise Control system may have
limits to its ability to detect distance to
the vehicle ahead due to road and traffic
conditions.
On curves
OADAS014SD
• Smart Cruise Control system may
not detect a moving vehicle in your
lane, and then your vehicle could
accelerate to the set speed. Also, the
vehicle speed will decrease when the
vehicle ahead is recognized suddenly.
• Select the appropriate set speed
on curves and apply the brakes or
accelerator pedal if necessary.
OADAS015SD
Your vehicle speed can be reduced due
to a vehicle in the adjacent lane.
Apply the accelerator pedal and select
the appropriate set speed. Check to be
sure that the road conditions permit safe
operation of Smart Cruise Control.
On inclines
OADAS012SD
• During uphill or downhill driving,
Smart Cruise Control system 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 decrease when the
vehicle ahead is recognized suddenly.
• Select the appropriate set speed
on inclines and apply the brake or
accelerator pedal if necessary.
