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 only is
moved by the electric motor.

approximately 6 seconds each time you
turn the engine start/stop button to the
ON position.

warning light does not come on, or
continuously remains on after operating

engine start/stop button to the ON posi-
tion or started the engine, or if it comes

start/stop button is turned ON and goes
off in approximately 3 seconds if the sys-
tem is operating normally.

the assistance of the anti-lock brake sys-
tem.

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
The brake warning light turned on when
the regenerative brake system is not
operated with brake system malfunction.
Have the system checked by an author-
ized HYUNDAI dealer as soon as possi-
ble.
When the brake function is not well or the
regenerative brake system is not operat-
ed with brake system malfunction, the
brake warning light turned on and 'check
brake' is displayed on the LCD. Have the
system checked by an authorized
HYUNDAI dealer as soon as possible.
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 brake function is not well
and the regenerative brake system is
not operated with brake system mal-
function, the brake warning light
turned on with 'check brake' is dis-
played on the LCD and warning
chime will sound. In this condition
you 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 HYUNDAI
dealer as soon as possible.

transaxle shift position is selected.
✽ ✽

ly, Gear are not displayed.
WARNING - Low tire pres-
sure
Significantly low tire pressure
makes the vehicle unstable and can
contribute to loss of vehicle control
and increased braking distances.
Continued driving on tires with low
pressure will cause the tires to
overheat and fail.
WARNING - Safe stopping
The TPMS cannot alert you to
severe and sudden tire damage
caused by external factors.
If you feel any vehicle instability,
immediately take your foot off the
accelerator, apply the brakes
gradually and with light force,
and slowly move to a safe posi-
tion off the road.

Features of your vehicle
Battery saver function
The purpose of this feature is to pre-
vent the battery from being dis-
charged. The system automatically
turns off the parking lights when the
driver turns off the hybrid system and
opens the driver-side door.
With this feature, the parking lights will
be turned off automatically if the driver
parks on the side of road at night.
If necessary, to keep the lights on
when the smart key is turned, perform
the following:
1) Open the driver-side door.
2) Turn the parking lights OFF and ON
again using the light switch on the
steering column.
Headlamp delay (if equipped)
If you turn the engine start/stop button to
the ACC or OFF position with the head-
lights ON, the headlights (and/or tail
lights) remain on for about 20 minutes.
However, if the driver’s door is opened
and closed, the headlights are turned off
after 30 seconds.
The headlights can be turned off by
pressing the lock button on the smart key
twice or turning the light switch to the
OFF or Auto position.
However, if you turn the light switch to the
Auto position when it is dark outside, the
headlights will not be turned off.
Headlamp welcome function
When the headlight switch is in the ON or
AUTO position and all doors (and trunk)
are closed and locked, if you press the
door unlock button on the smart key, the
headlights will come on for about 15 sec-
onds. At this time, if you press the door
lock button on the smart key, the head-
lights will turn off immediately.
Daytime running light
(if equipped)
Daytime Running Lights (DRL) can make
it easier for others to see the front of your
vehicle during the day. DRL can be help-
ful in many different driving conditions,
and it is especially helpful after dawn and
before sunset.
The DRL system will turn OFF when:
1. The headlight is ON.
2. Engine stops.
3. If the multifuntion switch is on “DRL
OFF” position.
4. Parking brake ON.

through doors other than the (dri-
ver's door), the battery saver func-
tion does not operate and the head

matically. Therefore, the battery may
become discharged. In this case,
