Driving your vehicle
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 con-
ditions permit safe operation of
Smart Cruise Control.
On inclines
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.
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 radar may not detect immedi-
ately when a vehicle cuts in sud-
denly. Always pay attention to the
traffic, road and driving conditions.
If a slower vehicle moves into your
lane, your speed may decrease to
maintain the distance to the vehicle
ahead.
If a faster vehicle which moves into
your lane, your vehicle will acceler-
ate to the set speed.

Vehicle recognition
Some vehicles in your lane cannot
be recognized by the sensor:
- Vehicles offset to one side
- Slow-moving vehicles or sudden-
decelerating vehicles
- Stopped vehicles
- Vehicles with small rear profile
such as trailers with no loadsA 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
luggage compartment
- While the steering wheel is operat-
ing
- When driving to one side of the
lane
- When driving on narrow lanes or
on curves
Apply the brake or accelerator pedal
if necessary. 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.

The lane marker is very thick or
thin.
The lane is very wide or narrow.
The lane marker ahead is not visi-
ble due to rain, snow, water on the
road, damaged or stained road
surface, or other factors.
The shadow is on the lane marker
by a median strip, trees, guardrail,
noise barriers, etc.
The lane markers are complicated
or a structure substitutes for the
lines such as a construction area.
There are crosswalk signs or other
symbols on the road.
The lane marker in a tunnel is
stained with oil, etc.
The lane suddenly disappears
such as at the intersection.When external condition is inter-
vened

light or an oncoming vehicle is
reflected on a wet road surface
such as a puddle in the road.
The field of view in front is
obstructed by sun glare.
There is not enough distance
between you and the vehicle in
front to be able to detect the lane
marker or the vehicle ahead is driv-
ing on the lane marker. Driving on a steep grade, over a
hill, or when driving on a curved
road.
The adverse road conditions cause
excessive vehicle vibrations while
driving.
The surrounding of the inside rear
view mirror temperature is high
due to direct sunlight, etc.
When front visibility is poor
The windshield or the camera lens
is blocked with dirt or debris.
The windshield glass is fogged up;

bumper clean for proper operation of
the system. The system may not work prop-
erly when the bumper has been
damaged, or if the rear bumper
has been replaced or repaired.
The system may turn off if inter-
fered by strong electromagnetic
waves.
Always keep the sensors clean.
NEVER disassemble the sensor
component or apply any impact
on the sensor component.
Be careful not to apply unneces-
sary force on the radar sensor or
sensor cover. If the sensor is
forcibly moved out of proper
alignment, the system may not
operate correctly. In this case, a
warning message may not be dis-
played. We recommend that you
have the vehicle inspected by an
authorized HYUNDAI dealer.
Do not apply foreign objects
such as a bumper sticker or a
bumper guard near the radar
sensor or apply paint to the sen-
sor area. Doing so may adverse-
ly affect the performance of the
sensor.

What to do in an emergency
The TPMS Malfunction Indicator
may illuminate after blinking for
one minute if the vehicle is near
electric power supply cables or
radio transmitters such as police
stations, government and public
offices, broadcasting stations,
military installations, airports,
transmitting towers, etc.

Indicator may illuminate if snow
chains are used or electronic
devices such as computers, charg-
ers, remote starters, navigation,
etc. This may interfere with normal
operation of the TPMS.
Changing a Tire with TPMS
If you have a flat tire, the Low Tire
Pressure and LCD position indicator
will come on. Have the flat tire
repaired by an authorized HYUNDAI
dealer as soon as possible or
replace the flat tire with the spare
tire.Once the original tire equipped with
a tire pressure monitoring sensor is
reinflated to the recommended pres-
sure and reinstalled on the vehicle,
the Low Tire Pressure LCD position
indicator and TPMS Malfunction
Indicator will go off within a few min-
utes of driving.
If the indicators do not disappear
after a few minutes, please visit an
authorized HYUNDAI dealer.
Each wheel is equipped with a tire
pressure sensor mounted inside the
tire behind the valve stem. You must
use TPMS specific wheels. It is rec-
ommended that you always have
your tires serviced by an authorized
HYUNDAI dealer.
NOTICE
