If the brake fluid level in the reser-
voir is low:
1. Drive carefully to the nearest safelocation and stop your vehicle.
2. With the engine stopped, check the brake fluid level immediately
and add fluid as required (For
more details, refer to "Brake

brake fluid, check all brake com-
ponents for fluid leaks. If a brake
fluid leak is found, or if the warning
light remains on, or if the brakes
do not operate properly, do not
drive the vehicle. Have the vehicle
inspected by an authorized
HYUNDAI dealer.
Dual-diagonal braking system
Your vehicle is equipped with dual-
diagonal braking systems. This
means you still have braking on two
wheels even if one of the dual sys-
tems 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. Also, the vehicle will not stop in as
short a distance with only a portion
of the brake system working.
If the brakes fail while you are driv-
ing, shift to a lower gear for addition-
al engine braking and stop the vehi-
cle as soon as it is safe to do so.

This warning light illuminates:
Once you set the ignition switch or
the Engine Start/Stop button to the
ON position.
- It illuminates for approximately 3seconds and then goes off.
When there is a malfunction with the ABS (The normal braking sys-
tem will still be operational without
the assistance of the anti-lock
brake system).
In this case, have your vehicle
inspected by an authorized
HYUNDAI dealer.
Parking Brake & Brake Fluid
Warning Light
Driving the vehicle with a warn-
ing 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 your vehicle
inspected by an authorized

comes equipped with a wireless cel-
lular phone charger.
The system is available when all
doors are closed, and when the igni-
tion switch is ON.

system charges only the Qi-enabled
cellular phones ( ). Read the label
on the cellular phone accessory
cover or visit your cellular phone
manufacturer's website to check
whether your cellular phone supports
the Qi technology.
The wireless charging process starts
when you put a Qi-enabled cellular
phone on the wireless charging unit.
1. Remove other items, including thesmart key, from the wireless charg-
ing unit. If not, the wireless charg-
ing process may be interrupted.
Place the cellular phone on the
center of the charging pad ( ).
2. The indicator light is orange when the cellular phone is charging. The
indicator light turns green when
phone charging is complete.
3. You can turn ON or OFF the wire- less charging function in the user
settings mode on the instrument
cluster. For further information,
refer to the "LCD Display Modes"
in this chapter. If your cellular phone is not charging:
- Slightly change the position of the
cellular phone on the charging
pad.

charging process, and re-attempt to
charge your cellular phone again.
The system warns you with a mes-
sage on the LCD display if the cellular
phone is still on the wireless charging
unit after the engine is turned OFF
and the front door is opened.
Information
For some manufacturers' cellular
phones, the system may not warn you
even though the cellular phone is left
on the wireless charging unit. This is
due to the particular characteristic of
the cellular phone and not a malfunc-
tion of the wireless charging.

Carbon monoxide (CO) gas is toxic. Breathing CO can cause unconsciousness and death.
Engine exhaust contains carbon monoxide which cannot be seen or smelled.
Do not inhale engine exhaust.
If at any time you smell engine exhaust inside the vehicle, open the windows immediately. Exposure to CO can
cause unconsciousness and death by asphyxiation.
Be sure the exhaust system does not leak.
The exhaust system should be checked whenever the vehicle is raised to change the oil or for any other purpose.
If you hear a change in the sound of the exhaust or if you drive over something that strikes the underneath side of
the vehicle, have the exhaust system checked as soon as possible by an authorized HYUNDAI dealer.
Do not run the engine in an enclosed area.
Letting the engine idle in your garage, even with the garage door open, is a hazardous practice. Run the engine
only long enough to start the engine and to move the vehicle out of the garage.
Avoid idling the engine for prolonged periods with people inside the vehicle.
If it is necessary to idle the engine for a prolonged period with people inside the vehicle, be sure to do so only in
an open area with the air intake set at "Fresh" and fan control set to high so fresh air is drawn into the interior.
Keep the air intakes clear.
To assure proper operation of the ventilation system, keep the ventilation air intakes located in front of the wind-
shield clear of snow, ice, leaves, or other obstructions.
If you must drive with the trunk open:
Close all windows.
Open instrument panel air vents.
Set the air intake control at "Fresh", the air flow control at "Floor" or "Face", and the fan control set to high.
