Limitations of the System
Forward Collision-Avoidance Assist
system is designed to help monitor
the vehicle ahead in the roadway
through camera recognition to warn
the driver that a collision is imminent,
and if necessary, apply emergency
braking.
In certain situations, the camera may
not be able to detect the vehicle
ahead. In these cases, FCA system
may not operate normally. The driver
must pay careful attention in the fol-
lowing situations where FCA opera-
tion may be limited.
Detecting vehicles
The sensor may be limited when:
The front view camera is blocked
with a foreign object or debris
The front view camera lens is con-
taminated due to tinted, filmed or
coated windshield, damaged
glass, or stuck of foreign matter
(sticker, bug, etc.) on the glass
Inclement weather such as heavy
rain or snow obscures the field of
view of the camera
The vehicle is on unpaved or
uneven rough surfaces, or road
with sudden gradient changes.
The camera sensor recognition is
limited
The vehicle in front is too small to
be detected (for example a motor-
cycle or a bicycle, etc.)
The front view camera does not
recognize the entire vehicle in
front.
The vehicle in front is an oversize
vehicle or trailer that is too big to
be detected by the camera recog-
nition system (for example a tractor
trailer, etc.)
5
FCA system does not operate
when the vehicle is in reverse.
FCA system is not designed
to detect other objects on the
road such as animals.
FCA system does not detect
vehicles in the opposite lane.
FCA system does not detect
cross traffic vehicles that are
approaching.
FCA system cannot detect the
driver approaching the side
view of a parked vehicle (for
example on a dead end
street.)
In these cases, you must main-
tain a safe braking distance,
and if necessary, depress the
brake pedal to reduce the driv-
ing speed in order to maintain a
safe distance.

The severe weather conditions of
winter quickly wear out tires and
cause other problems. To minimize
winter driving problems, you should
take the following suggestions:
Snow or Icy Conditions
You need to keep sufficient distance
between your vehicle and the vehicle
in front of you.
Apply the brakes gently. Speeding,
rapid acceleration, sudden brake
applications, and sharp turns are
potentially very hazardous practices.
During deceleration, use engine
braking to the fullest extent. Sudden
brake applications on snowy or icy
roads may cause the vehicle to skid.
To drive your vehicle in deep snow, it
may be necessary to use snow tires
or to install tire chains on your tires.
Always carry emergency equipment.
Some of the items you may want to
carry include tire chains, tow straps
or chains, a flashlight, emergency
flares, sand, a shovel, jumper cables,
a window scraper, gloves, ground
cloth, coveralls, a blanket, etc.
Snow tires
If you mount snow tires on your vehi-
cle, make sure to use radial tires of
the same size and load range as the
original tires. Mount snow tires on all
four wheels to balance your vehicle’s
handling in all weather conditions.
The traction provided by snow tires
on dry roads may not be as high as
your vehicle's original equipment
tires. Check with the tire dealer for
maximum speed recommendations.
Information
Do not install studded tires without
first checking local, state and munici-
pal regulations for possible restric-
tions against their use.
Tire chains
Since the sidewalls of radial tires are
thinner than other types of tires, they
may be damaged by mounting some
types of tire chains on them.
Therefore, the use of snow tires is
recommended instead of tire chains.
If tire chains must be used, use gen-
uine HYUNDAI parts and install the
tire chain after reviewing the instruc-
tions provided with the tire chains.
Damage to your vehicle caused by
improper tire chain use is not cov-
ered by your vehicle manufacturer’s
warranty.
i
Snow tires should be equivalent
in size and type to the vehicle's
standard tires. Otherwise, the
safety and handling of your
vehicle may be adversely affect-
ed.

- When using tire chains:
Wrong size chains or improperly
installed chains can damage
your vehicle's brake lines, sus-
pension, body and wheels.
Use SAE "S" class or wire
chains.
If you hear noise caused by
chains contacting the body,
retighten the chain to prevent
contact with the vehicle body.
To prevent body damage,
retighten the chains after driving
0.3~0.6 miles (0.5~1.0 km).
Do not use tire chains on vehi-
cles equipped with aluminum
wheels. If unavoidable, use a
wire type chain.
Use wire chains less than 0.47
inch (12 mm) wide to prevent
damage to the chain's connec-
tion.
Winter Precautions
Use high quality ethylene glycol
coolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because
it helps prevent corrosion in the cool-
ing system, lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolant
in accordance with the maintenance
schedule in chapter 7. Before winter,
have your coolant tested to assure
that its freezing point is sufficient for
the temperatures anticipated during
the winter.
Change to "winter weight" oil if
necessary
In some climates it is recommended
that a lower viscosity "winter weight"
oil be used during cold weather. See
chapter 8 for recommendations. If
you aren't sure what weight oil you
should use, consult an authorized
HYUNDAI dealer.
Check battery and cables
Winter puts additional burdens on
the battery system. Visually inspect
the battery and cables as described
in chapter 7. The level of charge in
your battery can be checked by an
authorized HYUNDAI dealer or a
service station.

mum combined weight of occupants
and cargo. If your vehicle is equipped
with a trailer, the combined weight
includes the tongue load.
Seating capacity
Total : 5 persons
(Front seat : 2 persons,
Rear seat : 3 persons)
Seating capacity is the maximum
number of occupants including a
driver, your vehicle may carry.
However, the seating capacity may
be reduced based upon the weight of
all of the occupants, and the weight
of the cargo being carried or towed.
Do not overload the vehicle as there
is a limit to the total weight, or load
limit including occupants and cargo,
the vehicle can carry. The label located on the driver's door
sill gives the original tire size, cold

Tire Pressure Monitoring
System
Each tire, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehi-
cle manufacturer on the vehicle plac-
ard or tire inflation pressure label. (If
your vehicle has tires of a different
size than the size indicated on the
vehicle placard or tire inflation pres-
sure label, you should determine the
proper tire inflation pressure for
those tires.)As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale when one or more of your
tires is significantly under-inflated.
Accordingly, when the low tire pres-
sure telltale illuminates, you should
stop and check your tires as soon as
possible, and inflate them to the
proper pressure. Driving on a signifi-
cantly underinflated tire causes the
tire to overheat and can lead to tire
failure.
Under-inflation also reduces fuel effi-
ciency and tire tread life, and may
affect the vehicle's handling and
stopping ability.
Please note that the TPMS is not a
substitute for proper tire mainte-
nance, and it is the driver's responsi-
bility to maintain correct tire pres-
sure, even if under-inflation has not
reached the level to trigger illumina-
tion of the TPMS low tire pressure
telltale.Your vehicle has also been equipped
with a TPMS malfunction indicator to
indicate when the system is not
operating properly.
The TPMS malfunction indicator is
combined with the low tire pressure
telltale. When the system detects a
malfunction, the telltale will flash for
approximately one minute and then
remain continuously illuminated. This
sequence will continue upon subse-
quent vehicle start-ups as long as
the malfunction exists.
When the malfunction indicator is
illuminated, the system may not be
able to detect or signal low tire pres-
sure as intended. TPMS malfunc-
tions may occur for a variety of rea-
sons, including the installation of
replacement or alternate tires or
wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunction
telltale after replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or alter-
nate tires and wheels allow the
TPMS to continue to function proper-
ly. Over-inflation or under-inflation
can reduce tire life, adversely
affect vehicle handling, and
lead to sudden tire failure that
may cause loss of vehicle con-
trol resulting in an accident.
