Driving your vehicle
- Driving on a slope
The performance of Forward
Collision-Avoidance Assist system
may be decreased while driving
upward or downward on a slope. The
front camera or front radar sensor
recognition may not detect the vehi-
cle or pedestrian in front.
This may result in unnecessary
alarm and braking or no alarm and
braking when necessary.
When the system suddenly recog-
nizes the vehicle or pedestrian in
front while passing over a slope, you
may experience sharp deceleration.Always keep your eyes forward while
driving upward or downward on a
slope, and, if necessary, depress the
brake pedal to reduce your driving
speed in order to maintain distance.
- Changing lanes
When a vehicle changes lanes in
front of you, the FCA system may not
immediately detect the vehicle, espe-
cially if the vehicle changes lanes
abruptly. In this case, you must main-
tain a safe braking distance, and if
necessary, depress the brake pedal
to reduce your driving speed in order
to maintain a safe distance.

When driving in stop-and-go traffic,
and a stopped vehicle in front of you
merges out of the lane, the FCA sys-
tem may not immediately detect the
new vehicle that is now in front of
you. In this case, you must maintain
a safe braking distance, and if nec-
essary, depress the brake pedal to
reduce your driving speed in order to
maintain a safe distance.- Detecting the vehicle in front of you
If the vehicle in front of you has cargo
that extends rearward from the cab,
or when the vehicle in front of you
has higher ground clearance, addi-
tional special attention is required.
The FCA system may not be able to
detect the cargo extending from the
vehicle. In these instances, you must
maintain a safe braking distance
from the rearmost object, and if nec-
essary, depress the brake pedal to
reduce your driving speed in order to
maintain distance.
Detecting pedestrians
(if equipped)
The sensor may be limited when:
The pedestrian is not fully detected
by the camera recognition system,
for example, if the pedestrian is
leaning over or is not fully walking
upright
The pedestrian is moving very
quickly or appears abruptly in the
camera detection area
The pedestrian is wearing clothing
that easily blends into the back-
ground, making it difficult to be
detected by the camera recogni-
tion system
The outside lighting is too bright
(e.g. when driving in bright sunlight
or in sun glare) or too dark (e.g.
when driving on a dark rural road
at night)
It is difficult to detect and distin-
guish the pedestrian from other
objects in the surroundings, for
example, when there is a group of
pedestrians or a large crowd
There is an item similar to a per-
son's body structure

Do not use the Forward
Collision avoidance Assist
(FCA) system when towing a
vehicle. Application of the
FCA system while towing may
adversely affect the safety of
your vehicle or the towing
vehicle.
Use extreme caution when the
vehicle in front of you has
cargo that extends rearward
from the cab, or when the
vehicle in front of you has
higher ground clearance.
The FCA system is designed
to detect and monitor the vehi-
cle ahead or detect a pedestri-
an in the roadway through
radar signals and camera
recognition. It is not designed
to detect bicycles, motorcy-
cles, or smaller wheeled
objects such as luggage bags,
shopping carts, or strollers.

The color of indicator will
change depending on the
condition of LKA system.
- White :Sensor does not detect
lane lines or vehicle speed
is under 40mph (64 km/h).
- Green : Sensor detects lane lines
and the system is able to
control vehicle steering.LKA system operation
To see the LKA system screen on
the LCD display in the cluster,
select Assist mode ( ). For more
details, refer to "LCD Display
Modes" in chapter 3.
When both lane lines are detected
and all the conditions to activate
the LKA system are satisfied, a
green steering wheel indicator will
illuminate and the LKA system
indicator light will change from
white to green. This indicates that
the LKA system is in the
ENABLED state and the steering
wheel will be able to be controlled.
The Lane Keeping Assist (LKA)
system is a system to help pre-
vent the driver from leaving the
lane. However, the driver should
not solely rely on the system
but always check the road con-
ditions when driving.

Driving your vehicle
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:
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.
NEVER arbitrarily disassemble
the camera assembly, nor apply
any impact on the camera
assembly.
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 infor-
mation, 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)

Sensor to Detect Distance to
the Vehicle Ahead
The Smart Cruise Control uses a
sensor to detect distance to the vehi-
cle 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.
Do not use when:
- Driving in heavy traffic or
when traffic conditions make
it difficult to drive at a con-
stant speed
- Driving on rainy, icy, or
snow-covered roads
- When driving on hilly or
windy roads
- Driving in windy areas
- Driving in parking lots
- Driving near crash barriers
- Driving on a sharp curve
- Driving with limited view
(possibly due to bad weath-
er, such as fog, snow, rain or
sandstorm)
- The vehicle's sensing ability
decreases due to vehicle
modification, resulting in a
level difference of the vehi-
cle's front and rear- The smart cruise control is
supplemental systems to
assist you. Do not entirely
rely on the systems. Always
pay attention, while driving,
for your safety.
- When using the cruise con-
trol mode, you must manual-
ly adjust the distance to
other vehicles by depressing
the brake pedal. The system
does not automatically
adjust the distance to vehi-
cles in front of you.

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 engine (e.g. in an
open terrain).
Information
The SCC operation is temporarily dis-
abled if the radar is blocked, but if
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
OTM058061LDo not apply 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 pres-
surized water directly on the
sensor or sensor cover.
CAUTION
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

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.

What to do in an emergency
If any of the below happens, have
the system checked by an author-
ized HYUNDAI dealer.
1. The Low Tire Pressure TPMS
Malfunction Indicator does not
illuminate for 3 seconds when
the ignition switch is placed to
the ON position or engine is
running.
2. The TPMS Malfunction Indicator
remains illuminated after blink-
ing for approximately 1 minute.
3. The Low Tire Pressure LCD dis-
play remains illuminated
Low Tire Pressure
Telltale
Low Tire Pressure
LCD Display with
Position Indicator
When the tire pressure monitoring
system warning indicators are illumi-
nated and the warning message is
displayed on the cluster LCD display,
one or more of your tires is signifi-
cantly under-inflated. The LCD posi-
tion indicator will indicate which tire
is significantly under-inflated by illu-
minating the corresponding position
light.If any of your tire pressures are indi-
cated as being low, immediately
reduce your speed, avoid hard cor-
nering, and anticipate increased
stopping distances. You should stop
and check your tires as soon as pos-
sible. Inflate the tires to the proper
pressure as indicated on the vehi-
cle’s placard or tire inflation pressure
label located on the driver's side cen-
ter pillar outer panel.
If you cannot reach a service station
or if the tire cannot hold the newly
added air, replace the low pressure
tire with the spare tire.
The Low Tire Pressure LCD position
indicator will remain on and the
TPMS Malfunction Indicator may
blink for one minute and then remain
illuminated until you have the low
pressure tire repaired and replaced
on the vehicle.
The spare tire is not equipped with
a tire pressure sensor.
