Features of your vehicle
Turn signal indicator
The blinking arrows on the instrument
panel show the direction indicated by the
turn signals. If the arrow comes on but
does not blink, blinks more rapidly than
normal, or does not illuminate at all, a
malfunction in the turn signal system is
indicated. Your dealer should be consult-
ed for repairs.
High beam indicator
This indicator illuminates when the head-
lights are on and in the high beam posi-
tion or when the turn signal lever is pulled
into the Flash-to-Pass position.
Tail light indicator
This indicator illuminates when the tail
lights are on.
Engine oil pressure
warning light
This warning light indicates the engine oil
pressure is low.
If the warning light illuminates while driv-
ing:
1. Drive safely to the side of the road and
stop.
2. With the engine off, check the engine
oil level. If the level is low, add oil as
required.
If the warning light remains on after
adding oil or if oil is not available, call an
authorized HYUNDAI dealer.
CAUTION
If the engine is not stopped imme-
diately after the engine oil pressure
warning light is illuminated, severe
damage could result.
CAUTION
If the oil pressure warning light
stays on while the engine is run-
ning, serious engine damage may
result. The oil pressure warning
light comes on whenever there is
insufficient oil pressure. In normal
operation, it should come on when
the engine start/stop button is
turned on, then go out when the
engine is started. If the oil pressure
warning light stays on while the
engine is running, there is a serious
malfunction.
If this happens, stop the car as
soon as it is safe to do so, turn off
the engine and check the oil level. If
the oil level is low, fill the engine oil
to the proper level and start the
engine again. If the light stays on
with the engine running, turn the
engine off immediately. In any
instance where the oil light stays on
when the engine is running, the
engine should be checked by an
authorized HYUNDAI dealer before
the car is driven again.

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

This light illuminated when the parking
brake is applied with engine start/stop
button in the START or ON position. The

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.

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.

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,

ON position, and will go out in a few sec-
onds after the engine is started. If it illu-
minates while driving, or does not illumi-
nate when the engine start/stop button is

cle to your nearest authorized HYUNDAI
dealer and have the system checked.
Generally, your vehicle will continue to be
drivable, but have the system checked by
an authorized HYUNDAI dealer promptly.
