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, we recommend that the system be
immediately inspected by an authorized
HYUNDAI dealer.
We recommend 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 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.
• We recommend that inflated air
bags be 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.
We recommend that you consult
an authorized HYUNDAI dealer for
the necessary information. Failure
to follow these precautions could
increase the risk of personal injury.

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.
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 lever or the paddle shifters (if
equipped) to shift to a lower gear.
