Reminder Indicator (SRI)
The SRS service reminder indicator (SRI)
comes on and flashes for about 6 seconds
after the ignition key is turned to the "ON"
position or after the engine is started, after
which it will go out.
This light also comes on when the SRS is not
working properly. If the SRI does not come on,
or continuously remains on after flashing for
about 6 seconds when you turned the ignition
key to the "ON" position or started the engine,
or if it comes on while driving, have the SRS
inspected by an authorized Hyundai Dealer.
B260P02Y-GATABS Service Reminder
Indicator (SRI) (If Installed)
When the key is turned to the "ON" position, the
Anti-Lock Brake System will come on and then
go off in a few seconds. If the ABS SRI remains
on, comes on while driving, or does not come
on when the key is turned to the "ON" position,
this indicates that there may be a problem with
the ABS.
If this occurs, have your vehicle checked by
your Hyundai dealer as soon as possible. The
normal braking system will still be operational,
but without the assistance of the anti-lock
brake system.
WARNING:If the both ABS SRI and Parking Brake/
Brake fluid level warning lights remain "ON"
or come on while driving, there may be a
problem with E.B.D (Electronic Brake Force
Distribution).
If this occurs, avoid sudden stops and have
your vehicle checked by your Hyundai dealer
as soon as possible.

opening. If a lock is covered with ice, squirt it with
an approved de-icing fluid to remove the ice. If
the lock is frozen internally, you may be able to
thaw it out by using a heated key. Handle the
heated key with care to avoid burning the fingers.

Don't Let Your Parking Brake FreezeUnder some conditions your parking brake can
freeze in the engaged position. This is most likely
to happen when there is an accumulation of snow
or ice around or near the rear brakes or if the
brakes are wet. If there is a risk the parking brake
may freeze, apply it only temporarily while you
put the gear selector lever in "P" (automatic) or in
first or reverse gear (manual transaxle) and
block the rear wheels so the car cannot roll. Then
release the parking brake.
