Seats & Safety System3-64
SRS Care
The SRS is virtually maintenance-free
and there are no parts you can safely
service by yourself. If the SRS air bag
warning light does not illuminate when
the Engine Start/Stop button is in the
ON position, or continuously remains on,
have your vehicle immediately inspected
by an authorized HYUNDAI dealer.
Any work on the SRS system, such as
removing, installing, repairing, or any
work on the steering wheel, the front
passenger’s panel, front seats and roof
rails must be performed by an authorized
HYUNDAI dealer. Improper handling of
the SRS system may result in serious
personal injury. WARNING
To reduce the risk of serious injury or
death take the following precautions:

[ Do not attempt to modify or
disconnect the SRS components or
wiring, including the addition of any
kind of badges to the pad covers or
modifications to the body structure.

[ Do not place objects over or near
the air bag modules on the steering
wheel, instrument panel, and the
front passenger’s panel above the
glove box.

[ Clean the air bag pad covers with
a soft cloth moistened with plain
water. Solvents or cleaners could
adversely affect the air bag covers
and proper deployment of the
system.

[ Always have inflated air bags
replaced by an authorized HYUNDAI
dealer.

[ If components of the air bag system
must be discarded, or if the vehicle
must be scrapped, certain safety
precautions must be observed.
Consult an authorized HYUNDAI
dealer for the necessary information.
Failure to follow these precautions
could increase the risk of personal
injury.

Additional Safety Precautions
Passengers should not move out of
or change seats while the vehicle is
moving. A passenger who is not wearing
a seat belt during a crash or emergency
stop can be thrown against the inside of
the vehicle, against other occupants, or
be ejected from the vehicle.
Do not use any accessories on seat
belts. Devices claiming to improve
occupant comfort or reposition the seat
belt can reduce the protection provided
by the seat belt and increase the chance
of serious injury in a crash.
Do not modify the front seats.
Modification of the front seats could
interfere with the operation of the
supplemental restraint system sensing
components or side air bags.
Do not place items under the front
seats. Placing items under the front seats
could interfere with the operation of the
supplemental restraint system sensing
components and wiring harnesses.
Do not cause impact to the doors.
Impact to the doors when the Engine
Start/Stop button is in the ON or START
position may cause the air bags to
inflate.
Modifications to accommodate
disabilities. If you require modification
to your vehicle to accommodate
a disability, contact the HYUNDAI
Customer Connect Center at 800-633-
5151.
Adding equipment to or modifying
your air bag equipped vehicle
If you modify your vehicle by changing
your vehicle’s frame, bumper system,
front end or side sheet metal or ride
height, this may affect the operation of
your vehicle’s air bag system.
Air Bag Warning Labels
ODN8039057L
Air bag warning labels, required by the
U.S. National Highway Traffic Safety
Administration (NHTSA), are attached
to alert the driver and passengers of
potential risks of the air bag system.
Be sure to read all of the information
about the air bags that are installed on
your vehicle in this Owners Manual.

the seat belt is not fastened.
For more details, refer to “Seat Belts”
section in chapter 3.
Air bag warning light
This warning light illuminates:

[ When y
ou set the ignition switch or
the Engine Start/Stop button to the
ON position.
- The air bag warning light illuminates for about 3 ~ 6 seconds and then
turns off when all checks have been
performed.

[ The air bag warning light will remain

Parking brake warning light
This warning light illuminates:

[When y
ou set the ignition switch or
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 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 loca
tion and stop your vehicle.
2. With the engine stopped, check the brake fluid level immediately and add
fluid as required (For more details,
refer to “Brake Fluid” section 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 br

aking 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.
Also, the vehicle will not stop in as short
a distance with only a portion of the
brake system working.
If you experience a malfunction with
the brake system while driving, attempt
to slow your vehicle by coasting or
by using engine braking. You may be
able to reduce your vehicle speed by
manually downshifting to a lower gear.
Use Manual Shift Mode using either the
gear shift button or the paddle shifters (if
equipped) to shift to a lower gear.
