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)
between 2,000 rpm and 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.

Warning and Indicator Lights
Information
Make sure that all warning lights are OFF
after starting the engine. If any light is still
ON, this indicates a situation that needs
attention.
Air Bag Warning Light
This warning light illuminates:
• When you place the Engine Start/Stop
button to the ON position.
-The air bag warning light illuminates
for about 6 seconds and then turns
off when all checks have been
performed
• The air bag warning light will remain
illuminated if there is a malfunction
with the Safety Restraint System (SRS)
air bag operation.
In this case, have the vehicle
inspected by an authorized HYUNDAI
dealer.
Seat Belt Warning Light
This warning light informs the driver that the seat belt is not fastened.
For more information, refer to “Seat
Belts” in chapter 3.
Parking Brake & Brake Fluid
Warning Light
This warning light illuminates:
• When you place the Engine Start/Stop
button to the ON position.
-The parking brake light illuminates
for about 3 seconds and will then
turn off once the parking brake is
released.
• Whenever the parking brake is
applied.
• Whenever the brake fluid level in the
reservoir is low.
-If the warning light illuminates
with the parking brake released, it
indicates that the brake fluid level in
the reservoir is low.
• Whenever the regenerative brake
does not operate.
If the brake fluid level in the reservoir is
low:
1. Drive carefully to the nearest safe
location and stop your vehicle.
2. With the engine stopped, check
the brake fluid level immediately
and add fluid as required (For more
information, refer to "Brake Fluid" in
chapter 8). After adding brake fluid,
check all brake components for fluid
leaks. If a brake fluid leak is found, or
if the warning light remains on, or if
the brakes do not operate properly, do
not drive the vehicle. Have the vehicle
inspected by an authorized HYUNDAI
dealer.

Dual-diagonal braking system
Your vehicle is equipped with dual-
diagonal braking system. This means you
still have braking on two wheels even if
one of the dual systems should fail.
With only one of the dual systems
working, more than normal pedal travel
and greater pedal pressure is required to
stop the vehicle.
If the brakes fail while you are driving,
shift to a lower gear for additional engine
braking and stop the vehicle as soon as it
is safe to do so.
WARNING
Parking Brake & Brake Fluid Warning
Light
Driving the vehicle with a warning light
ON is dangerous. If the Parking Brake &
Brake Fluid Warning Light illuminates
with the parking brake released, it
indicates that the brake fluid level is
low.
In this case, have the vehicle inspected
by an authorized HYUNDAI dealer.
Regenerative brake warning
light
(yellow)
This warning light illuminates:
When the regenerative brake does not
operate and the brake does not perform
well. This causes the Brake Warning
light (red) and Regenerative Brake
Warning Light (yellow) to illuminate
simultaneously.
If this occurs, drive safely and we
recommend that you have the vehicle
inspected by an authorized HYUNDAI
dealer.
The operation of the brake pedal may
be more difficult than normal and the
braking distance may increase.
Anti-lock Brake System (ABS)
Warning Light
This warning light illuminates:
• When you place the Engine Start/Stop
button to the ON position.
-The ABS warning light illuminates
for about 3 seconds and then turns
off.
• Whenever there is a malfunction with
the ABS.
Note that the hydraulic braking
system will still be operational even if
there is a malfunction with the ABS.
Electronic Brake Force
Distribution (EBD) System
Warning Light
These two warning lights illuminate at the same time while driving:
When the ABS and regular brake system
may not work normally.
In this case, have the vehicle inspected
by an authorized HYUNDAI dealer.
WARNING
Electronic Brake Force Distribution
(EBD) System Warning Light
When both ABS and Parking Brake &
Brake Fluid Warning Lights are on, the
brake system will not work normally
and you may experience an unexpected
and dangerous situation during sudden
braking.
In this case, avoid high speed driving
and abrupt braking.
Have the vehicle inspected by an
authorized HYUNDAI dealer as soon as
possible.

Forward/Reverse Parking
Distance Warning System
Precautions
• Forward/Reverse Parking Distance
Warning system may not sound
consistently depending on the speed
and shapes of the objects detected.
• Forward/Reverse Parking Distance
Warning system may malfunction if
the vehicle bumper height or sensor
installation has been modified or
damaged. Any non-factory installed
equipment or accessories may also

may be inoperative until the stains are
removed using a soft cloth.
• Do not push, scratch or strike the
sensor. Sensor damage could occur.
• Do not spray the sensors or its
surrounding area directly with a high
pressure washer. Shock applied from
high pressure water may cause the
