Information
• The fuel tank capacity is given in
chapter 2.
• The fuel gauge is supplemented by
a low fuel warning light, which will
illuminate when the fuel tank is nearly
empty.
• On inclines or curves, the fuel gauge
pointer may fluctuate or the low fuel
warning light may come on earlier than
usual due to the movement of fuel in
the tank.
WARNING
Running out of fuel can expose vehicle
occupants to danger.
You must stop and obtain additional
fuel as soon as possible after the
warning light comes on or when the
gauge indicator comes close to the "E
(Empty)" level.
NOTICE
Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire and damage
the catalytic converter.

• When you place the Engine Start/Stop
button to the ON position.
-The air bag warning light illuminates
for about 6 seconds and then turns
off when all checks have been
performed

indicates that the brake fluid level in
the reservoir is low.
• Whenever the regenerative brake
does not operate.
If the brake fluid level in the reservoir is
low:
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 (For more
information, refer to "Brake Fluid" in

Dual-diagonal braking system
Your vehicle is equipped with dual-
diagonal braking system. This means you
still have braking on two wheels even if
one of the dual systems should fail.
With only one of the dual systems
working, more than normal pedal travel
and greater pedal pressure is required to
stop the vehicle.
If the brakes fail while you are driving,
shift to a lower gear for additional engine
braking and stop the vehicle as soon as it
is safe to do so.
WARNING
Parking Brake & Brake Fluid Warning
Light
Driving the vehicle with a warning light
ON is dangerous. If the Parking Brake &
Brake Fluid Warning Light illuminates
with the parking brake released, it
indicates that the brake fluid level is
low.
In this case, have the vehicle inspected
by an authorized HYUNDAI dealer.

simultaneously.
If this occurs, drive safely and we
recommend that you have the vehicle
inspected by an authorized HYUNDAI
dealer.
The operation of the brake pedal may

braking.
In this case, avoid high speed driving
and abrupt braking.
Have the vehicle inspected by an
authorized HYUNDAI dealer as soon as
possible.
