Warnings and indicators
All warning lights are checked by turning
the engine start/stop button ON (do not
start the engine). Any light that does not
illuminate should be checked by an
authorized HYUNDAI dealer.
After starting the Hybrid system, check to
make sure that all warning lights are off.
If any are still on, this indicates a situa-
tion that needs attention. When releasing
the parking brake, the brake system
warning light should go off. The fuel
warning light will stay on if the fuel level
is low.
EV mode
This light illuminates if the vehicle is
moved only by the electric motor.
Service indicator
This indicator comes on when any mal-
function occurs in the hybrid system. If
this occurs, have your vehicle checked by
an authorized HYUNDAI dealer.
Air bag warning light
This warning light will illuminate for
approximately 6 seconds each time you
turn the engine start/stop button to the
ON position.
This light also comes on when the
Supplemental Restraint System (SRS) is
not working properly. If the SRS air bag
warning light does not come on, or
continuously remains on after operating
for about 6 seconds when you turned the
engine start/stop button to the ON posi-
tion or started the engine, or if it comes
on while driving, have the SRS inspected

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
on while driving, or does not come on when
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.
Electronic brake force distri-
bution (EBD) system warning
light
If these two warning lights illuminate at
the same time while driving, your vehicle
may have a malfunction with the ABS
and EBD system. Have the vehicle checked by an author-
ized HYUNDAI dealer as soon as possi-
ble.
✽ ✽
NOTICE
If the ABS warning light or EBD warn-
ing light is on and stays on, the
speedometer or odometer/tripmeter
may not work. In this case, have your
vehicle checked by an authorized
HYUNDAI dealer as soon as possible.

chime will activate to the following table
when the engine start/stop button is in
"ON" position.

ble.

WARNING
Driving the vehicle with a warning
light on is dangerous. If the brake
warning light remains on, have the
brakes checked and repaired imme-
diately by an authorized HYUNDAI
dealer.
Brake system &
Parking brake & Brake fluid warning light
When the service brake system or the
regenerative brake system malfunctions,
the brake warning light is turned on and
'check brake' is displayed on the LCD.
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.
