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.
• Ensure that the floor mats are
securely attached to the vehicle’s
floor mat anchor(s) before driving
the vehicle.
• Do not use ANY floor mat that cannot
be firmly attached to the vehicle’s
floor mat anchors.
• Do not stack floor mats on top of one
another (e.g. all-weather rubber mat
on top of a carpeted floor mat). Only
a single floor mat should be installed
in each position.
IMPORTANT - Your vehicle was
manufactured with driver’s side floor
mat anchors that are designed to
securely hold the floor mat in place.
To avoid any interference with pedal
operation, HYUNDAI recommends that
the HYUNDAI floor mat designed for use
in your vehicle be installed.
Luggage net holder (if equipped)

Roof side rails
ONX4050057
If your vehicle comes with roof side rails,
then roof side rails crossbars can be
installed on top of your vehicle.
The roof side rails crossbars are an
accessory and are available at your
HYUNDAI dealer.
NOTICE
If the vehicle is equipped with a
sunroof, be sure not to position cargo
onto the roof side rails in such a way
that it could interfere with sunroof
operation.
NOTICE
• When carrying cargo on the roof side
rails, take the necessary precautions
to make sure the cargo does not
damage the roof of the vehicle.
• When carrying large objects on the
roof side rails, make sure they do
not exceed the overall roof length or
width.
WARNING
• The following specification is the
maximum weight that can be loaded
onto the roof side rails. Distribute the
load as evenly as possible onto the
roof side rails and secure the load
firmly.
Loading cargo or luggage in excess
of the specified weight limit on the
roof side rails may damage your
vehicle.
ROOF SIDE
RAILS 220 lbs. (100 kg)
EVENLY DISTRIBUTED
• The vehicle center of gravity will be
higher when items are loaded onto
the roof side rails. Avoid sudden
starts, braking, sharp turns, abrupt
maneuvers or high speeds that may
result in loss of vehicle control or
rollover resulting in an accident.
• Always drive slowly and turn corners
carefully when carrying items on the
roof side rails. Severe wind updrafts,
caused by passing vehicles or natural
causes, can cause sudden upward
pressure on items loaded on the
roof side rails. This is especially true
when carrying large, flat items such
as wood panels or mattresses. This
could cause the items to fall off the
roof side rails and cause damage to
your vehicle or others around you.
• To prevent damage or loss of cargo
while driving, check frequently
before or while driving to make sure
the items on the roof side rails are
securely fastened.

Driving your vehicle

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 liftgate, 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 seat belt. Check that all
passengers have fastened their seat
belts.
• 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” section 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 or take drugs and drive.
Drinking 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.

Safety chains
You should always attach chains between
your vehicle and your trailer.
Instructions about safety chains may
be provided by the hitch manufacturer
or trailer manufacturer. Follow the
manufacturer’s recommendation for
attaching safety chains. Always leave just
enough slack so you can turn with your
trailer. And, never allow safety chains to
drag on the ground.
Trailer brakes
If your trailer is equipped with a braking
system, make sure it conforms to
your country’s regulations and that
it is properly installed and operating
correctly.
If your trailer weighs more than the
maximum trailer weight without trailer
brakes loaded, then it needs its own
brakes and they must be adequate. Be
sure to read and follow the instructions
for the trailer brakes so you’ll be able
to install, adjust and maintain them
properly. Be sure not to modify your
vehicle’s brake system.
WARNING
Do not use a trailer with its own brakes
unless you are absolutely certain that
you have properly set up the brake
system. This is not a task for amateurs.
Use an experienced, competent trailer
shop for this work.
Driving with a trailer
Towing a trailer requires a certain
amount of experience. Before setting
out for the open road, you must get to
know your trailer. Acquaint yourself with
the feel of handling and braking with the
added weight of the trailer. And always
keep in mind that the vehicle you are
driving is now longer and not nearly as
responsive as your vehicle is by itself.
Before you start, check the trailer hitch
and platform, safety chains, electrical
connector(s), lights, tires and brakes.
During your trip, occasionally check
to be sure that the load is secure, and
that the lights and trailer brakes are still
working.
Distance
Stay at least twice as far behind the
vehicle ahead as you would when driving
your vehicle without a trailer. This can
help you avoid situations that require
heavy braking and sudden turns.
Passing
You will need more passing distance up
ahead when you’re towing a trailer. And,
because of the increased vehicle length,
you’ll need to go much farther beyond
the passed vehicle before you can return
to your lane.

Certification label
OBH059070
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.
