Anti-lock brake system
(ABS) warning light
This light illuminates if the engine
start/stop button is turned ON and goes
off in approximately 3 seconds if the sys-
tem is operating normally.
If the ABS warning light remains on, comes

the engine start/stop button is turned to the
ON position, this indicates that there may
be a malfunction with the ABS.
If this occurs, have your vehicle checked
by an authorized HYUNDAI dealer as
soon as possible. The normal braking sys-
tem will still be operational, but without the
assistance of the anti-lock brake system.

bution (EBD) system warning

ized HYUNDAI dealer as soon as possi-
ble.

diately by an authorized HYUNDAI
dealer.

Have the system checked by an author-
ized HYUNDAI dealer as soon as possi-
ble.
Parking brake warning
This light illuminated when the parking
brake is applied with engine start/stop
button in the START or ON position. The
warning light should go off when the
parking brake is released. Low brake fluid level warning
If the warning light remains on, it may
indicate that the brake fluid level in the
reservoir is low.
If the warning light remains on:
1. Drive carefully to the nearest safe
location and stop your vehicle.
2. With the engine stopped, check the brake fluid level immediately and add
fluid as required. Then check all brake
components for fluid leaks.
3. Do not drive the vehicle if leaks are found, the warning light remains on or
the brakes do not operate properly.
Have the vehicle towed to any author-
ized HYUNDAI dealer for a brake sys-
tem inspection and necessary repairs.
Your vehicle is equipped with a dual-
diagonal braking system. This means you
still have braking on two wheels even if
one of the brake circuits is damaged or
malfunctions. With only one of the circuits
working, more than normal pedal travel
and greater pedal pressure are required
to stop the car. Also, the car will not stop
in as short a distance with only a portion
of the brake system working. If the
brakes fail while you are driving, shift to a
lower gear for additional engine braking
and stop the car as soon as it is safe to
do so. To check bulb operation, check whether
the parking brake and brake fluid warning
light illuminates when the engine
start/stop button is in the ON position.
CAUTION
When the service brake system and
the regenerative brake system mal-functions, the brake warning light is turned on and 'check brake' is dis-played on the LCD, and also the warn- ing chime will sound. If this occursyou can stop your vehicle by apply-ing greater force to the brake pedal than normal and the stopping dis-tance will be longer. Have the system checked by an authorized HYUNDAIdealer as soon as possible.
