The Driver Attention Warning sys-
tem utilizes the camera sensor on
the front windshield for its opera-
tion. To keep the camera sensor in
the best condition, you should
observe the followings:
Do not disassemble the camera
temporarily to tint the window or
to attach any types of coatings
and accessories. If you disas-
semble a camera and assemble
it again, take your vehicle to an
authorized HYUNDAI dealer and
have the system checked for cal-
ibration.
NEVER install any accessories
or stickers on the front wind-
shield, nor tint the front wind-
shield.
NEVER locate any reflective
objects (i.e. white paper, mirror)
over the dashboard. Any light
reflection may cause a malfunc-
tion of the Driver Attention Alert
(DAW) system.
Pay extreme caution to keep the
camera sensor out of water.
NOTICE
The Driver Attention Warning
(DAW) system may not properly
operate with limited alerting in
the following situations:
The lane detection perform-
ance is limited. (For more
details, refer to "Lane Keeping
Assist (LKA) system" in this
chapter.)
The vehicle is violently driven
or is abruptly turned for obsta-
cle avoidance (e.g. construc-
tion area, other vehicles, fallen
objects, bumpy road).
Forward drivability of the vehi-
cle is severely undermined
(possibly due to wide variation
in tire pressures, uneven tire
wear-out, toe-in/toe-out align-
ment).
The vehicle drives on a curvy
road.
The vehicle drives on a bumpy
road.
The vehicle drives through a
windy area.
The vehicle is controlled by the
following driving assist sys-
tems:
- Lane Keeping Assist (LKA)
system
- Forward Collision-Avoidance
Assist (FCA) system
- Smart Cruise Control (SCC)
system
- Lane Following Assist (LFA)
system
CAUTION
Playing the vehicle audio sys-
tem at high volume may offset
the Driver Attention Warning
(DAW) system warning sounds.

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
The Smart Cruise Control uses a

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.Warning message
Smart Cruise Control disabled.
Radar blocked
When the sensor lens cover is
blocked with dirt, snow, or debris, the
Smart Cruise Control system opera-
tion 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 the Smart Cruise Control
system. The Smart Cruise Control
system may not properly activate, if
the radar is totally contaminated, or if
any substance is not detected after
turning on the vehicle (e.g. in an
open terrain).
Information
For the SCC operation is temporarily
stopped if the radar is blocked, but
you wish to use conventional cruise
control mode (speed only control func-
tion), you must convert to the cruise
control mode (refer to "To convert to
Cruise Control mode" in the following
page).
i
OFE058181LDo 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.

Driving your vehicle
Check Smart Cruise Control System
The message will appear when the
vehicle to vehicle distance control
system is not functioning normally.
Take your vehicle to an authorized
HYUNDAI dealer and have the sys-
tem checked.
Limitations of the System
The Smart Cruise Control system
may have limits to its ability to detect
distance to the vehicle ahead due to
road and traffic conditions.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, the 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, the 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.

Driving your vehicle
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.
Detecting vehicles
Some vehicles in your lane cannot
be recognized by the sensor:
- 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 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.

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.
Additionally, the TPMS Malfunction
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.
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
Never use a puncture-repairing
agent not approved by HYUNDAI
dealer to repair and/or inflate a
low pressure tire. Tire sealant
not approved by HYUNDAI deal-
er may damage the tire pressure
sensor.

pressor.
Information
The pressure gauge may show higher
than actual reading when the com-
pressor is running. To get an accurate
tire pressure, the compressor needs to
be turned off.
Information
When reinstalling the repaired or
replaced tire and wheel on the vehicle,
tighten the wheel lug nut to 79~94
lbf·ft (11~13kgf·m).

When you use the Tire Mobility Kit
including sealant not approved by
HYUNDAI, the tire pressure sen-
sors may be damaged by sealant.
The sealant on the tire pressure
sensor and wheel should be
removed when you replace the
tire with a new one and inspect
the tire pressure sensors at an
authorized dealer.
CAUTION
The tire inflation pressure must
be at least 32 psi (220 kPa). If it
is not, do not continue driving.
