•
In addition to inflating in certain side
collisions, vehicles equipped with a
rollover sensor, side and curtain air
bags will inflate if the sensing system
detects a rollover.
When a rollover is detected, side and
curtain air bags will remain inflated
longer to help provide protection
from ejection, especially when used in
conjunction with the seat belts.
• To help provide protection, the air
bags must inflate rapidly. The speed
of air bag inflation is a consequence
of extremely short time in which
to inflate the air bag between the
occupant and the vehicle structures
before the occupant impacts those
structures. This speed of inflation
reduces the risk of serious or life-
threatening injuries and is thus a
necessary part of air bag design.
However, the rapid air bag inflation can also cause injuries which can
include facial abrasions, bruises and
broken bones because the inflation
speed also causes the air bags to
expand with a great deal of force.
• There are even circumstances under
which contact with the air bag can
cause fatal injuries, especially if the
occupant is positioned excessively
close to the air bag.
You can take steps to help reduce the
risk of being injured by an inflating air
bag. The greatest risk is sitting too close
to the air bag. An air bag needs space to
inflate. It is recommended that drivers sit
as far as possible between the center of
the steering wheel and the chest while
still maintaining control of the vehicle.
WARNING
To reduce the risk of serious injury or
death from an inflating air bag, take the
following precautions: • NEVER place a child restraint in the
front passenger seat.
Always properly restrain children
under age 13 in the rear seats of the
vehicle.
• Adjust the front passenger’s and
driver’s seats as far to the rear as
possible while allowing you to
maintain full control of the vehicle.
• Hold the steering wheel with
hands at the 9 o’clock and 3 o’clock positions.
• NEVER place anything or anyone
between the air bag and the seat
occupant.
• Do not allow the front passenger
to place their feet or legs on the
dashboard.

Seats & Safety System
Do Not Install a Child Restraint in the
Front Passenger’s Seat
OHI039193N
Even though your vehicle is equipped
with the OCS, never install a child
restraint in the front passenger’s seat.
An inflating air bag can forcefully strike a
child or child restraint resulting in serious
or fatal injury.
WARNING
• NEVER place a rear-facing or front-
facing child restraint in the front
passenger’s seat of the vehicle.
• An inflating frontal air bag could
forcefully strike a child resulting in
serious injury or death.
• Always properly restrain children in
an appropriate child restraint in the
rear seat of the vehicle.
Why Didn’t My Air Bag Go Off in
a Collision?
Air bags are not designed to inflate in
every collision. There are certain types
of accidents in which the air bag would
not be expected to provide additional
protection. These include rear impacts,
second or third collisions in multiple
impact accidents, as well as low speed
impacts. Damage to the vehicle indicates
a collision energy absorption, and is not
an indicator of whether or not an air bag
should have inflated.
WARNING
To reduce the risk of an air bag
deploying unexpectedly and causing
serious injury or death: • Do not hit or allow any objects to
impact the locations where air bags
or sensors are installed.
• Do not perform maintenance on or
around the air bag sensors. If the
location or angle of the sensors is
altered, the air bags may deploy
when they should not or may not
deploy when they should.
• Do not install bumper guards or
replace the bumper with a non-
genuine HYUNDAI parts. This may
adversely affect the collision and air
bag deployment performance.
• Place the ignition switch in the
LOCK/OFF or ACC position when the
vehicle is being towed to prevent
inadvertent air bag deployment.
• Have all air bag repairs conducted by
an authorized HYUNDAI dealer.

Dual-diagonal braking system
Your vehicle is equipped with dual-
diagonal braking systems. 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. Anti-lock Brake System (ABS)
Warning Light
This warning light illuminates:
•
When you place the ignition switch 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.

Information
When engine oil pressure decreases due to insufficient engine oil, etc., the Engine Oil
Pressure warning light will illuminate. In
addition, the enhanced engine protection
system which limits engine power will
be activated. If the engine oil pressure is
restored, the Engine Oil Pressure warning
light and the enhanced engine protection
system will turn off. However, for gasoline 2.5 turbo engine, when the engine oil
pressure is restored, the warning light and
the enhanced engine protection system will
turn off after the engine is restarted.
NOTICE
• If the engine is not turned OFF
immediately after the Engine
Oil Pressure Warning Light is
illuminated, severe damage could
occur.
• If the warning light stays on while the
engine is running, it indicates that
there may be serious engine damage or malfunction. In this case:
1. Stop the vehicle as soon as it is safe to do so.
2. Turn off the engine and check the oil level. If the oil level is low, fill
the engine oil to the proper level.
3. Start the engine again. If the warning light stays on after the
engine has started, turn the
engine off immediately. In this
case, have the vehicle inspected
by an authorized HYUNDAI dealer.
Low Fuel Level Warning Light
This warning light illuminates:
When the fuel tank is nearly empty. Add fuel as soon as possible.
NOTICE
Driving with the Low Fuel Level warning
light on or with the fuel level below "E"
can cause the engine to misfire and
damage the catalytic converter.
Master Warning Light
This indicator light illuminates:
When there is a malfunction in operation
in any of the following systems:
- Forward Collision-Avoidance Assist system malfunction (if equipped)
- Forward Collision-Avoidance Assist radar blocked (if equipped)
- Blind-Spot Collision Warning system malfunction (if equipped)
