Detergent Fuel Additives
HYUNDAI recommends that you use
good quality gasolines treated with
detergent additives such as TOP TIER
Detergent Gasoline, which help prevent
deposit formation in the engine. These
gasolines will help the engine run
cleaner and enhance performance of
the Emission Control System. For more
information on TOP TIER Detergent
Gasoline, please go to the website (www.
toptiergas.com ).
For customers who do not use TOP Tier
Detergent Gasoline regularly, and have
problems starting or the engine does
not run smoothly, detergent-based
fuel additives that you can purchase
separately may be added to the gasoline.
If TOP TIER Detergent Gasoline is
not available, one bottle of additive
added to the fuel tank according to the
maintenance schedule is recommended
(refer to the Maintenance Schedule in
chapter 8).
Additives are available from your
authorized HYUNDAI dealer along with
information on how to use them. Do not
mix other additives.
Operation in foreign countries
If you are going to drive your vehicle in
another country, be sure to:
• Observe all regulations regarding
registration and insurance.
• Determine that acceptable fuel is
available. •
This vehicle should not be modified.
Modification of your vehicle could
affect its performance, safety or
durability and may even violate
governmental safety and emissions
regulations.
In addition, damage or performance
problems resulting from any
modification may not be covered
under warranty.
• If you use unauthorized electronic
devices, it may cause the vehicle to
operate abnormally, wire damage,
battery discharge and fire. For your
safety, do not use unauthorized
electronic devices.
VEHICLE BREAK-IN
PROCESS
By following a few simple precautions for
the first 600 miles (1,000 km) you may
add to the performance, economy and
life of your vehicle.
• Do not race the engine.
• While driving, keep your engine speed
(rpm, or revolutions per minute) below
4,000 rpm.
• Do not maintain a single speed for
long periods of time, either fast or
slow. Varying engine speed is needed
to properly break-in the engine.
• Avoid hard stops, except in
emergencies, to allow the brakes to
seat properly.
• Don’t tow a trailer during the first
1,200 miles (2,000 km) of operation.
• Fuel economy and engine
performance may vary depending on
vehicle break-in process and stabilize
after driving about 3,700 miles (6,000
km). Engine may consume more oil
during the vehicle break-in period.

Rear Seats
Folding the rear seat (if equipped)
The rear seatbacks can be folded to
facilitate carrying long items or to
increase the luggage capacity of the
vehicle.
WARNING
• Never allow passengers to sit on top
of the folded down seatback while
the vehicle is moving. This is not a
proper seating position and no seat
belts are available for use. This could
result in serious injury or death in
case of an accident or sudden stop.
• Objects carried on the folded down
seatback should not extend higher
than the top of the front seatbacks.
This could allow cargo to slide
forward and cause injury or damage
during sudden stops.
To fold down the rear seatback:
1. Set the front seatback to the upright
position and if necessary, slide the
front seat forward.

4. Slowly allow the shoulder portion of
the seat belt to retract and listen for
an audible “clicking” or “ratcheting”
sound. This indicates that the retractor
is in the “Automatic Locking” mode.
If no distinct sound is heard, repeat
steps 3 and 4.
5. Remove as much slack from the belt
as possible by pushing down on the
child restraint system while feeding
the shoulder belt back into the
retractor.
6. Push and pull on the child restraint
system to confirm that the seat belt
is holding it firmly in place. If it is not,
release the seat belt and repeat steps
2 through 6.
7. Double check that the retractor is in
the “Automatic Locking” mode by
attempting to pull more of the seat
belt out of the retractor. If you cannot,
the retractor is in the “Automatic
Locking” mode.If your CRS (child restraint system)
manufacturer instructs or recommends
you to use a tether anchor with the lap/
shoulder belt, refer to the previous pages
for more information.
Information
When the seat belt is allowed to retract to
its fully stowed position, the retractor will
automatically switch from the “Automatic
Locking” mode to the emergency lock
mode for normal adult usage.
WARNING
If the retractor is not in the “Automatic
Locking” mode, the child restraint
can move when your vehicle turns or
stops suddenly. A child can be seriously
injured or killed if the child restraint
is not properly anchored in the car,
including manually pulling the seat belt
all the way out to shift the rectractor to
the “Automatic Locking” mode.
To remove the child restraint, press the
release button on the buckle and then
pull the lap/shoulder belt out of the
restraint and allow the seat belt to retract
fully.

For example, if a child restraint of the
type specified in the regulations is on the
seat, the occupant classification sensor
can detect it and cause the air bag to
turn OFF.
Front passenger seat adult occupants
who are properly seated and wearing the
seat belt properly, should not cause the
passenger air bag to be automatically
turned OFF. For small adults it may be
turned OFF, however, if the occupant
does not sit in the seat properly (for
example, by not sitting upright, by sitting
on the edge of the seat, or by otherwise
being out of position), this could cause
the sensor to turn the air bag OFF.
You will find the “PASSENGER AIR BAG
OFF” indicator on the overhead console.
This system detects the conditions 1-4
in the following table and activates or
deactivates the front passenger air bag
based on these conditions.
Always be sure that you and all vehicle
occupants are seated properly and
wearing the seat belt properly for the
most effective protection by the air bag
and the seat belt.
Never install a Child Restraint System in
the front passenger’s seat. If you should
install a CRS (Child Restraint System)
inevitably, use a forward-facing CRS with
3-point ALR safety seat belt and adjust
the front passenger’s seat as far to the
rear as possible. If the PASSENGER AIR
BAG “OFF” indicator is OFF after a CRS
(Child Restraint System) is equipped,
the front passenger’s airbag is operating
so you should install the CRS in the rear
seats of the vehicle immediately.The OCS may not function properly if the
passenger takes actions which can affect
the classification system. These include:
•
Failing to sit in an upright position.
• Leaning against the door or center
console.
• Sitting towards the sides of the front
of the seat.
• Putting their legs on the dashboard or
resting them on other locations which
reduce the passenger weight on the
front seat.
• Wearing the seat belt improperly.
• Reclining the seatback.
• Wearing a thick cloth like ski wear or
hip protection wear.
• Putting an additional thick cushion on
the seat.
• Putting electrical devices (e.g.
notebook, satellite radio) on the seat
with inverter charging.
