The cabin air filter is installed behind the
front trunk. It filters the dust or other
pollutants that enter the vehicle through
the heating and air conditioning system.
Have the cabin air filter replaced by an
authorized HYUNDAI dealer according to
the maintenance schedule. If the vehicle
is being driven in severe conditions such
as dusty or rough roads, more frequent
cabin air filter inspections and changes
are required.
If the air flow rate suddenly decreases,
have the system inspected at an
authorized HYUNDAI dealer.
Checking the amount of air
conditioner refrigerant and
compressor lubricant
When the amount of refrigerant is low,
the performance of the air conditioning
is reduced. Overfilling also reduces the
performance of the air conditixoning
system.
Therefore, if abnormal operation is
found, have the system inspected by an
authorized HYUNDAI dealer.
NOTICE
It is important that the correct type and
amount of oil and refrigerant is used.
Otherwise, damage to the compressor
and abnormal system operation may
occur. To prevent damage, the air
conditioning system in your vehicle
should only be serviced by trained and
certified technicians.
NOTICE
The refrigerant system should only
be serviced by trained and certified
technicians to insure proper and safe
operation.
The refrigerant system should be
serviced in a well-ventilated place.
The air conditioning evaporator (cooling
coil) shall never be repaired or replaced
with one removed from a used or
salvaged vehicle and new replacement
MAC evaporators shall be certified
(and labeled) as meeting SAE Standard J2842.

CAUTION
• Do not apply license plate frame or
foreign objects such as a bumper
sticker or a bumper guard near the
radar sensor. Doing so may adversely
affect the sensing performance of
the radar.
• Always keep the radar sensor and
lens cover clean and free of dirt and debris.
• Use only a soft cloth to wash the
vehicle. Do not spray pressurized
water directly on the sensor or
sensor cover.
• Be careful not to apply unnecessary
force on the radar sensor or sensor
cover. If the sensor is forcibly
moved out of proper alignment,

Power-Assist Brakes
Your vehicle has power-assisted brakes
that adjust automatically through normal usage.
If the vehicle is not running or is turned
off while driving, the power assist for
the brakes will not work. You can still
stop your vehicle by applying greater
force to the brake pedal than typical.
The stopping distance, however, will be
longer than with power brakes.
When the vehicle is not running, the
reserve brake power is partially depleted
each time the brake pedal is applied.
Do not pump the brake pedal when the
power assist has been interrupted.
WARNING
Take the following precautions: • Do not drive with your foot resting
on the brake pedal. This will create
abnormal high brake temperatures,
excessive brake lining and pad wear,
and increased stopping distances.
So increase the regeneration braking
level with the left paddle shift lever
to decrease the speed.
• When descending down a long or
steep hill, use the paddle shifter to
increase the regeneration braking
level in order to decrease your
speed without using the brake
pedal excessively. Applying the
brakes continuously will cause
the brakes to overheat and could
result in a temporary loss of braking
performance.
• Wet brakes may impair the vehicle's
ability to safely decelerate. Because
wet brakes increase braking distance
and cause noise troubles, select 0
step of the regenerative braking
system and depress the brake pedal
around 10 times, with keeping the
safe distance from other vehicles,
lightly in order to dry the braking
system. Such procedure may
decrease the driving distance by
restraining the regenerative braking
system, which is not a system
malfunction. Inspect the braking
system after car wash or driving over
wet road conditions.
NOTICE
• Do not continue depressing
the brake pedal if the ""
indicator is OFF. The battery may be
discharged.
• Noise and vibration generated
during braking is normal.
• Under normal operation, electric
brake pump noise and motor
vibration may occur temporarily in
below cases.
- When the pedal is depressed
suddenly.
- When the pedal is repeatedly
depressed in short intervals.
- When the ABS function is activated
while braking.

NOTICE
Driving with wheels and tires with
different sizes may cause the ESC
system to malfunction. Before replacing
tires, make sure all four tires and wheels
are the same size. Never drive the
vehicle with different sized wheels and
tires installed. ESC OFF usage
When Driving
The ESC OFF mode should only be used
briefly to help free the vehicle if stuck in
snow or mud, by temporarily stopping
operation of ESC, to maintain wheel
torque.
To turn ESC off while driving, press the
ESC OFF button while driving on a flat
road surface.
NOTICE
To prevent damage to the reduction gear: • Do not allow wheel(s) of one axle to
spin excessively while the ESC, ABS,
and Parking Brake warning lights
are displayed. The repairs would not
be covered by the vehicle warranty.
Reduce motor power and do not spin
the wheel(s) excessively while these
lights are displayed.
• When operating the vehicle
on a dynamometer, make sure
ESC is turned off (ESC OFF light
illuminated).
Information
• Turning ESC off does not affect ABS or standard brake system operation.
• Select 0 step of the regenerative
braking system and depress the brake
pedal around 10 times to efficiently apply brake disc cleaning.
Brake disc cleaning may decrease the
driving distance by restraining the
regenerative braking system. After
brake disc cleaning, the regenerative
braking system may be restored.
If the regenerative braking system
is not restored after the brake disc cleaning, have the vehicle inspected by
an authorized HYUNDAI dealer.
