Floor Mat Anchor(s)
ALWAYS use the Floor Mat Anchors to
attach the front floor mats to the vehicle.
The anchors on the front floor carpet
keep the floor mats from sliding forward.
WARNING
Do not overlay additional mats or liners
over the floor mats. If using All Weather
mats, remove the carpeted floor mats
before installing them. Only use floor
mats designed to connect to the
anchors.
WARNING
The following must be observed when
installing ANY floor mat to the vehicle. • Ensure to remove a protective
film attached on the carpet
before attaching a floor mat on
the front floor carpet. Otherwise,
the floor mat may move freely on
the protective film and it could
result in unintentional braking or
accelerating.

Before Entering the Vehicle
• Be sure all windows, outside mirror(s),
and outside lights are clean and
unobstructed.
• Remove frost, snow, or ice.
• Visually check the tires for uneven
wear and damage.
• Check under the vehicle for any sign
of leaks.
• Be sure there are no obstacles behind
you if you intend to back up.
Before Starting
• Make sure the hood, the trunk, and
the doors are securely closed and
locked.
• Adjust the position of the seat and
steering wheel.
• Adjust the inside and side view
mirrors.
• Verify all the lights work.
• Fasten your seatbelt. Check that
all passengers have fastened their
seatbelts.
• Check the gauges and indicators
in the instrument panel and the
messages on the instrument display
when the ignition switch is in the ON position.
• Check that any items you are carrying
are stored properly or fastened down
securely.
WARNING
To reduce the risk of SERIOUS INJURY or
DEATH, take the following precautions: • ALWAYS wear your seat belt. All
passengers must be properly belted
whenever the vehicle is moving.
For more information, refer to "Seat
Belts" in chapter 3.
• Always drive defensively. Assume
other drivers or pedestrians may be
careless and make mistakes.
• Stay focused on the task of driving.
Driver distraction can cause
accidents.
• Leave plenty of space between you
and the vehicle in front of you.
WARNING
NEVER drink alcohol or take drugs and
drive.
Drinking alcohol or taking drugs and
driving is dangerous and may result in
an accident and SERIOUS INJURY or
DEATH. Drunk driving is the number one
contributor to the highway death
toll each year. Even a small amount
of alcohol will affect your reflexes,
perceptions and judgment. Just
one drink can reduce your ability to
respond to changing conditions and
emergencies and your reaction time
gets worse with each additional drink.
Driving while under the influence
of drugs is as dangerous or more
dangerous than driving under the
influence of alcohol.
You are much more likely to have a
serious accident if you drink or take
drugs and drive. If you are drinking or
taking drugs, don't drive. Do not ride
with a driver who has been drinking
or taking drugs. Choose a designated
driver or call a taxi.

•
If the vehicle in front stops suddenly,
you may have less control of the
brake system. Therefore, always keep
a safe distance between your vehicle
and the vehicle in front of you.
• FCA system may activate during
braking and the vehicle may stop suddenly shifting loose objects
toward the passengers. Always keep
loose objects secured and fasten the
seat belt.
• FCA system may not activate if the
driver applies the brake pedal to
avoid collision.
• The brake control may be
insufficient, possibly causing a
collision, if a vehicle in front abruptly
stops. Always pay extreme caution.
• Occupants may get injured, if
the vehicle abruptly stops by the
activated FCA system. Pay extreme caution.
• FCA system operates only when the
system detect vehicles, pedestrian or
cyclist in front of the vehicle.
• FCA system may not activate
according to road conditions,
inclement weather, driving
conditions or traffic conditions.
• FCA system may not work for all
vehicles, passengers or cyclists.
WARNING
• 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 vehicles
that are stopped vertically to your
vehicle at a intersection or dead end
street.
• FCA system cannot detect the cross
traffic cyclist that are approaching.
In these cases, you must maintain a
safe braking distance, and if necessary,
depress the brake pedal to reduce the
driving speed in order to maintain a
safe distance or to stop the vehicle.
Limitations of the System
Forward Collision avoidance assist
system is designed to monitor the
vehicle ahead or a pedestrian or cyclist
in the roadway through radar signals
and camera recognition to warn the
driver that a collision is imminent, and if
necessary, apply emergency braking.
In certain situations, the radar sensor
or the camera may not be able to
detect the vehicle, pedestrian or cyclist
ahead. In these cases, FCA system may
not operate normally. The driver must
pay careful attention in the following
situations where FCA operation may be
limited.

Certification label
The certification label is located on the
driver’s door sill at the center pillar and
shows the maximum allowable weight of
the fully loaded vehicle. This is called the
GVWR (Gross Vehicle Weight Rating). The
GVWR includes the weight of the vehicle,
all occupants, fuel and cargo.
This label also tells you the maximum
weight that can be supported by the
front and rear axles, called Gross Axle
Weight Rating (GAWR).
The total weight of the vehicle, including
all occupants, accessories, cargo, and
trailer tongue load must not exceed the
Gross Vehicle Weight Rating (GVWR) or
the Gross Axle Weight Rating (GAWR).
To find out the actual loads on your front
and rear axles, you need to go to a weigh
station and weigh your vehicle. Be sure
to spread out your load equally on both
sides of the centerline.
WARNING
Overloading • Never exceed the GVWR for your
vehicle, the GAWR for either the front
or rear axle and vehicle capacity
weight. Exceeding these ratings
can affect your vehicle’s handling
and braking ability, and cause an
accident.
• Do not overload your vehicle.
Overloading your vehicle can cause
heat buildup in your vehicle’s tires
and possible tire failure, increased
stopping distances and poor vehicle
handling-all of which may result in a
crash.
NOTICE
Overloading your vehicle may cause
damage. Repairs would not be covered
by your warranty. Do not overload your
vehicle.
WARNING
If you carry items inside your vehicle
(e.g., suitcases, tools, packages, or
anything else), they are moving as fast
as the vehicle. If you have to stop or
turn quickly, or if there is a crash, the
items will keep going and can cause
an injury if they strike the driver or a
passenger. • Put items in the cargo area of your
vehicle. Try to spread the weight
evenly.
• Do not stack items, like suitcases,
inside the vehicle above the tops of
the seats.
• Do not leave an unsecured child
restraint in your vehicle.
• When you carry something inside the
vehicle, secure it.

Emergency Situations
7-16
If you have a tire gauge, check the tire
pressure (see “Tires and Wheels” in
chapter 2 for tire pressure instructions.).
If the pressure is lower or higher than
recommended, drive slowly to the
nearest service station and adjust it to
the recommended pressure. Always
reinstall the valve cap after checking
or adjusting tire pressure. If the cap
is not replaced, air may leak from the
tire. If you lose a valve cap, buy another
and install it as soon as possible. After
changing tires, secure the flat tire and
return the jack and tools to their proper
storage locations. If it is hard to secure
the flat tire, put the flat tire in the
luggage compartment.
NOTICE
• Check the tire pressure as soon
as possible after installing a spare
tire. Adjust it to the recommended
pressure.
• Check and tighten the wheel lug nuts
after driving over 50 km (30 miles) if
tires are replaced. Recheck the tire
wheel lug nuts after driving over
1,000 km (620 miles).
CAUTION
Your vehicle has metric threads on the
studs and lug nuts. Make certain during
tire changing that the same nuts that
were removed are reinstalled. If you
have to replace your lug nuts make
sure they have metric threads to avoid
damaging the studs and ensure the
wheel is properly secured to the hub.
Consult an authorized HYUNDAI dealer
for assistance.
If any of the equipment such as the jack,
lug nuts, studs, or other equipment is
damaged or in poor condition, do not
attempt to change the tire and call for
assistance.
Use of compact spare tires (if equipped)
Compact spare tires are designed for
emergency use only. Drive carefully on
the compact spare tire and always follow
the safety precautions.
WARNING
To prevent compact spare tire failure
and loss of control possibly resulting in
an accident: • Use the compact spare tire only in an
emergency.
• NEVER operate your vehicle over 80
km/h (50 mph).
• Do not exceed the vehicle’s
maximum load rating or the load
carrying capacity shown on the
sidewall of the compact spare tire.
• Do not use the compact spare tire
continuously. Repair or replace the
original tire as soon as possible to
avoid failure of the compact spare
tire.
