SRS warning light
The SRS (Supplement Restraint System)
air bag warning light on the instrument
panel displays the air bag symbol
depicted in the illustration. The system
checks the air bag electrical system for
malfunctions. The light indicates that
there is a potential malfunction with your
air bag system, which could include your
side and curtain air bags used for rollover
protection.
WARNING
If your SRS malfunctions, the air bag
may not inflate properly during an
accident increasing the risk of serious
injury or death.
If any of the following conditions occur,
your SRS is malfunctioning:
• The light does not turn on for
approximately three to six seconds
when the Engine Start/Stop button is
in the ON position.
• The light stays on after illuminating
for approximately three to six
seconds.
• The light comes on while the vehicle
is in motion.
• The light blinks when the engine is
running.
Have an authorized HYUNDAI dealer
inspect the SRS as soon as possible if
any of these conditions occur.
During a frontal collision, sensors will
detect the vehicle’s deceleration. If the
rate of deceleration is high enough, the
control unit will inflate the front air bags.
The front air bags help protect the driver
and front passenger by responding to
frontal impacts in which seat belts alone
cannot provide adequate restraint. When
needed, the side air bags help provide
protection in the event of a side impact
or rollover. •
Air bags are activated (able to inflate
if necessary) when the Engine Start/
Stop button is in the ON position or
approximately within 3 minutes after
ignition off.
• Air bags inflate in the event of certain
frontal or side collisions to help
protect the occupants from serious
physical injury.
• Generally, air bags are designed to
inflate based upon the severity of
a collision, its direction, etc. These
two factors determine whether
the sensors produce an electronic
deployment/inflation signal.
• The front air bags will completely
inflate and deflate in an instant. It is
virtually impossible for you to see the
air bags inflate during an accident. It is
much more likely that you will simply
see the deflated air bags hanging out
of their storage compartments after
the collision.
• 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.

• When you place the ignition switch to
the ON position.
- The air bag warning ligh

t 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.

Parking Brake & Brake Fluid
Warning Light
This warning light illuminates:
• When you place the ignition switch to
the ON position.
- The parking brak

e 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 ligh

t illuminates
with the parking brake released, it
indicates that the brake fluid level in
the reservoir is low.
If the brake fluid level in the reservoir is
low:
1.
Drive car

efully to the nearest safe
location and stop your vehicle.
2.
With the engine st

opped, check
the brake fluid level immediately
and add fluid as required (For more
information, refer to "Brake Fluid" in
chapter 9). 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 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.
