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 9).
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.

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, avoid sudden
acceleration.

[ 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 4,000 miles (6,000
km). Engine may consume more oil
during the vehicle break-in period.

Starting the Vehicle
Vehicles with smart key system
1. Carry the smart key or leave it inside the vehicle.
2. Make sure the parking brake is firmly applied.
3. Make sure the shift lever is in P (Park). With the shift lever in N (Neutral), you
cannot start the vehicle.
4. Depress the brake pedal.
5. Press the Engine Start/Stop button. If the hybrid system starts, the “
”
indicator will come on.
Whether the engine is cold or warm, it
should be started without depressing
the accelerator.
After following the start procedures, “
” indicator on the instrument cluster
will turn on. For more details, please
check chapter 6.
ECONOMICAL and SAFE OPERATION
of Hybrid system

[ Drive smoothly. Accelerate at a
moderate rate and maintain a steady
cruising speed. Do not make “jack-
rabbit” starts. Do not race between
stoplights.

[ Avoid heavy traffic whenever possible.
Always maintain a safe distance
from other vehicles so you can
avoid unnecessary braking. This also
reduces brake wear.

[ The regenerative brake generates
energy when the vehicle decelerates.

[ When the hybrid battery power is
low, the hybrid system automatically
recharges the hybrid battery.

[ When the engine is running with the
shift lever in N (Neutral), the hybrid
system cannot generate electricity.
The hybrid battery cannot recharge
with the shift lever in N (Neutral).
Information
In the hybrid system, the engine
automatically runs and stops. When
the hybrid system operates, the “
”
indicator is illuminated.
In the following situation, the engine may
operate automatically.
- When the engine is ready to run
- When the hybrid battery is being
charged
- Depending on the temperature
condition of the hybrid battery
Special Features
Hybrid vehicles sound different than
gasoline engine vehicles. When the
hybrid system operates, you may hear
a sound from the hybrid battery system
behind the rear seat. If you apply the
accelerator pedal rapidly, you may hear
an unconventional sound. When you
apply the brake pedal, you may hear
a sound from the regenerative brake
system. When the hybrid system is
turned off or on, you may hear a sound
in the engine compartment. If you
depress the brake pedal repeatedly
when the hybrid system is turned on,
you may hear a sound in the engine
compartment. None of these sounds
indicate a problem. These are normal
characteristics of hybrid vehicles.
If any of following occur, it’s a normal
condition if you hear a motor sound in
the engine compartment:
- After turning off the hybrid system, the brake pedal is released.
- When the hybrid system is turned off, the brake pedal is applied.
- When the driver door is opened.
DRIVING THE HYBRID VEHICLE

Foreword / Hybrid System Overview1-24
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 lever is in P (Park).
3. Turn ON the hazard warning flashers.
4. Turn OFF the vehicle, and try to start the hybrid system again, while
depressing the brake pedal and
turning on the ignition switch.
5. When the hybrid system still does not operate, refer to “If the 12 Volt Battery
Is Discharged” section in chapter 8.
Before jump-starting the vehicle,
check the fuel level and the exact
procedure to jump start. For further
details, refer to “If the 12 Volt Battery
Is Discharged” section in chapter
8. When the fuel level is low, do not
attempt to drive the vehicle only with
the battery power. The high voltage
battery may be discharged, and the

To release your seat belt:
Press the release button (1) in the locking
buckle.
When it is r
eleased, the belt should
automatically draw back into the
retractor. If this does not happen, check
the belt to be sure it is not twisted, then
try again.
Rear Seat Belt – Passenger’s 3-point
system with convertible locking
retractor
This type of seat belt combines the
features of both an emergency locking
retractor seat belt and an automatic
locking retractor seat belt. Convertible
retractor type seat belts are installed
in the rear seat positions to help
accommodate the installation of child
restraint systems. Although a convertible
retractor is also installed in the front
passenger seat position, NEVER place
any infant/child restraint system in the
front seat of the vehicle.
To fasten your seat belt:
Pull the seat belt out of the retractor
and insert the me
tal tab into the buckle.
There will be an audible “click” when
the tab locks into the buckle. When
not securing a child restraint, the seat
belt operates in the same way as the
driver’s seat belt (Emergency Locking
Retractor Type). It automatically adjusts
to the proper length only after the lap
belt portion of the seat belt is adjusted
manually so that it fits snugly across your
hips.
When the seat belt is fully extended from
the retractor to allow the installation of
a child restraint system, the seat belt
operation changes to allow the belt to
retract, but not to extend (Automatic
Locking Retractor Type). Refer to the
“Using a Child Restraint System” section
in this chapter.
NOTICE
Although the seat belt retractor
provides the same level of protection
for seated passengers in either
emergency or automatic locking
modes, the emergency locking mode
allows seated passengers to move
freely in their seat while keeping
some tension on the belt. During a
collision or sudden stop, the retractor
automatically locks the belt to help
restrain your body.
To deactivate the automatic locking
mode, unbuckle the seat belt and allow
the belt to fully retract.

Seats & Safety System3-24
NOTICE

[ Both the driver’s and front
passenger’s pre-tensioner seat belts
may be activated in certain frontal or
side collisions or rollovers.

[ When the pre-tensioner seat belts
are activated, a loud noise may be
heard and fine dust, which may
appear to be smoke, may be visible in
the passenger compartment. These
are normal operating conditions and
are not hazardous.

[ Although it is non-toxic, the fine
dust may cause skin irritation and
should not be inhaled for prolonged
periods. Wash all exposed skin areas
thoroughly after an accident in
which the pre-tensioner seat belts
were activated.
WARNING

[Fasten your seat belt while sitting
properly in an upright position to
maximize the effectiveness of the
pre-tensioner seat belt system.

[ A pre-tensioner seat belt system
is designed to activate only once.
Replace the pre-tensioner seat belt
system, if it was activated in an
accident.
Additional Seat Belt Safety
Precautions
Seat belt use during pregnancy
The seat belt should always be used
during pregnancy. The best way to
protect your unborn child is to protect
yourself by always wearing the seat belt.
Pregnant women should always wear
a lap-shoulder seat belt. Place the
shoulder belt across your chest, routed
between your breasts and away from
your neck. Place the lap belt line so
that it fits snugly and as low as possible
across the hips, not across the abdomen.
WARNING

[Pregnant women and patients are
more vulnerable to any impacts on
the abdomen during an abrupt stop
or accident. If you are in an accident
while pregnant, we recommend you
consult your doctor.

[ To reduce the risk of serious injury or
death to an unborn child during an
accident, pregnant women should
NEVER place the lap portion of the
seat belt above or over the area of
the abdomen where the unborn child
is located.
Seat belt use and children
Infant and small children
All 50 states have child restraint laws
which r

equire children to travel in
approved child restraint devices,
including booster seats. The age at
which seat belts can be used instead
of child restraints differs among states,
so you should be aware of the specific
requirements in your state, and where
you are travelling. Infant and child
restraints must be properly placed
and installed in a rear seat. For more
information refer to the “Child Restraint
Systems” section in this chapter.
