WARNING
If a fire occurs:
• If a small scale fire occurs, use a fire
extinguisher (ABC, BC) that is meant
for electrical fires.
If it is impossible to extinguish
the fire in the early stage, remain
a safe distance from the vehicle
and immediately call your local
fire emergency responders. Also,
advise them that a hybrid vehicle is
involved.
If the fire spreads to the high voltage
battery, large amount of water is
needed to put out the fire.
Using small amount of water or
fire extinguishers not meant for
electrical fires could cause serious
injury or death from electrical
shocks.
• Upon witnessing any sparks, gases,
flames, or fuel leakage of your
vehicle, immediately call emergency
services or contact an authorized
HYUNDAI dealer. Also, advise them
that a hybrid vehicle is involved.
WARNING
When a submersion in water occurs:
When your vehicle is flooded in water, a
high-voltage battery may cause shock
or fires. Thus, turn the hybrid system
OFF, take the key in your possession and
escape to a safe place. Never attempt
physical contact with your flooded
vehicle.
Immediately contact an authorized
HYUNDAI dealer and advise them that a
hybrid vehicle is involved.
When the Hybrid Vehicle Shuts
Off
When the high voltage battery or 12 volt
battery is discharged, or when the fuel
tank is empty, the hybrid system may
not operate while driving. When the
Hybrid system does not operate, do the
following:
1. Gradually reduce the vehicle speed.
Pull over your vehicle off the road in a
safe area.
2. Make sure the shift button is in P (Park).

Recommended SAE Viscosity Number
CAUTION
Always be sure to clean the area around any filler plug, drain plug, or dipstick before
checking or draining any lubricant. This is especially important in dusty or sandy
areas and when the vehicle is used on unpaved roads. Cleaning the plug and dipstick
areas will prevent dirt and grit from entering the engine and other mechanisms that
could be damaged.
Engine oil viscosity (thickness) has an effect on fuel economy and cold weather
operating (engine start and engine oil flowability). Lower viscosity engine oils can
provide better fuel economy and cold weather performance, however, higher viscosity
engine oils are required for satisfactory lubrication in hot weather. Using oils of any
viscosity other than those recommended could result in engine damage.
When choosing an oil, consider the range of temperature your vehicle will be operated
in before the next oil change. Proceed to select the recommended oil viscosity from
the chart.

(ILSAC). It is recommended to only use engine oils that uphold
this API Certification Mark.

Seats & Safety System3-2
You will find many safety precautions
and recommendations throughout this
section, and throughout this manual.
The safety precautions in this section are
among the most important.
Always Wear Your Seat Belt
A seat belt is your best protection in all
types of accidents. Air bags are designed
to supplement seat belts, not to replace
them. So even though your vehicle is
equipped with air bags, ALWAYS make
sure you and your passengers wear your
seat belts, and wear them properly.
Restrain All Children
All children under age 13 should ride
in your vehicle properly restrained in a
rear seat, not the front seat. Infants and
small children should be restrained in
an appropriate Child Restraint System.
Larger children should use a booster
seat with the lap/shoulder belt until they
can use the seat belt properly without a
booster seat.
Air Bag Hazards
While air bags can save lives, they can
also cause serious or fatal injuries to
occupants who sit too close to them, or
who are not properly restrained. Infants,
young children, and short adults are at
the greatest risk of being injured by an
inflating air bag. Follow all instructions
and warnings in this manual.
Driver Distraction
Driver distraction presents a serious and
potentially deadly danger, especially for
inexperienced drivers. Safety should be
the first concern when behind the wheel
and drivers need to be aware of the wide
array of potential distractions, such as
drowsiness, reaching for objects, eating,
personal grooming, other passengers,
and using mobile phones. Drivers can become distracted when
they take their eyes and attention off
the road or their hands off the wheel to
focus on activities other than driving.
To reduce your risk of distraction and an
accident:

[
Set up your mobile devices (for
example, MP3 players, phones,
navigation units, etc.) ONLY when
your vehicle is parked or safely
stopped.

[ ONLY use your mobile device when
allowed by laws and conditions
permit safe use. NEVER text or email
while driving. Most states have laws
prohibiting drivers from texting. Some
states and cities also prohibit drivers
from using handheld phones.

[ NEVER let the use of a mobile device
distract you from driving. You have a
responsibility to your passengers and
others on the road to always drive
safely, with your hands on the wheel
as well as your eyes and attention on
the road.
Control Your Speed
Excessive speed is a major factor in crash
injuries and deaths. Generally, the higher
the speed, the greater the risk, but
serious injuries can also occur at lower
speeds. Never drive faster than is safe
for current conditions, regardless of the
maximum speed posted.
Keep Your Vehicle in Safe
Condition
Having a tire blowout or a mechanical
failure can be extremely hazardous. To
reduce the possibility of such problems,
check your tire pressures and condition
frequently, and perform all regularly
scheduled maintenance.
IMPORTANT SAFETY PRECAUTIONS

3-5
Seat belts
Always fasten your seat belt before
starting any trip. At all times, passengers
should sit upright and be properly
restrained. Infants and small children
must be restrained in appropriate Child
Restraint Systems. Children who have
outgrown a booster seat and adults must
be restrained using the seat belts.
WARNING
Take the following precautions when
adjusting your seat belt:

[NEVER use one seat belt for more
than one occupant.

[ Always position the seatback upright
with the lap portion of the seat belt
snug and low across the hips.

[ NEVER allow children or small infants
to ride on a passenger’s lap.

[ Do not route the seat belt across your
neck, across sharp edges, or reroute
the shoulder strap away from your
body.

[ Do not allow the seat belt to become
caught or jammed.
Front Seats
WARNING
Take the following precautions when
adjusting your seat:

[NEVER attempt to adjust the seat
while the vehicle is moving. The seat
could respond with unexpected
movement and may cause loss
of vehicle control resulting in an
accident.

[ Do not place anything under the
front seats. Loose objects in the
driver’s foot area could interfere
with the operation of the foot pedals,
causing an accident.

[ Do not allow anything to interfere
with the normal position and proper
locking of the seatback.

[ Do not place a cigarette lighter on
the floor or seat. When you operate
the seat, gas may exit out of the
lighter causing a fire.

[ Use extreme caution when picking
up small objects trapped under the
seats or between the seat and the
center console. Your hands might be
cut or injured by the sharp edges of
the seat mechanism.

[ If there are occupants in the rear
seats, be careful while adjusting the
front seat position.

[ Make sure that the seat is locked in
place after the adjustment. If not,
the seat might move unexpectedly
resulting in an accident.
CAUTION
To prevent injury:

[Do not adjust your seat while
wearing your seat belt. Moving the
seat cushion forward may cause
strong pressure on your abdomen.

[ Do not allow your hands or fingers to
get caught in the seat mechanisms
while the seat is moving.

Seats & Safety System3-14
Head Restraint
The vehicle’s front and rear seats
have adjustable head restraints. The
head restraints provide comfort for
passengers, but more importantly they
are designed to help protect passengers
from whiplash and other neck and spinal
injuries during an accident, especially in
a rear impact collision.
WARNING
To help reduce, the risk of serious
injury or death in an accident, take the
following precautions when adjusting
your head restraints:

[ Always properly adjust the head
restraints for all passengers BEFORE
starting the vehicle.

[ NEVER let anyone ride in a seat
with the head restraint removed or
reversed.
OHI039190N

[Adjust the head restraints so the
middle of the head restraint is at the
same height as the height of the top
of the eyes.

[ NEVER adjust the head restraint
position of the driver’s seat when the
vehicle is in motion.

[ Adjust the head restraint as close to
the passenger’s head as possible. Do
not use a seat cushion that holds the
body away from the seatback.

[ Make sure the head restraint locks
into position after adjusting it.
WARNING
OTL035061
When sitting on the rear seat, do not
adjust the height of the head restraint
to the lowest position.
CAUTION
When there is no occupant in the rear
seats, adjust the height of the head
restraint to the lowest position. The
rear seat head restraint can reduce the
visibility of the rear area.
NOTICE
To prevent damage, NEVER hit or pull
on the head restraints.

Seats & Safety System3-18
Seat Warmers (if equipped)
Seat warmers are provided to warm the
seats during cold weather.
During mild weather or under conditions
where the operation of the seat warmer
is not needed, keep the seat warmers
OFF.
WARNING
The seat warmers can cause a SERIOUS
BURN, even at low temperatures and
especially if used for long periods of
time.
Passengers must be able to feel if the
seat is becoming too warm so they can
turn it off, if needed.
People who cannot detect temperature
change or pain to the skin should
use extreme caution, especially the
following types of passengers:

[ Infants, children, elderly or disabled
persons, or hospital outpatients.

[ People with sensitive skin or who
burn easily.

[ Fatigued individuals.

[ Intoxicated individuals.

[ People taking medication that can
cause drowsiness or sleepiness.
WARNING
NEVER place anything on the seat
that insulates against heat when the
seat warmer is in operation, such as a
blanket or seat cushion. This may cause
the seat warmer to overheat, causing a
burn or damage to the seat.
NOTICE
To prevent damage to the seat warmers
and seats:

[Never use a solvent such as paint
thinner, benzene, alcohol or gasoline
to clean the seats.

[ Do not place heavy or sharp objects
on seats equipped with seat
warmers.

[ Do not change the seat cover. It may
damage the seat warmer.
