Climate control air filter
The climate control air filter installed
behind the glove box filters the dust or
other pollutants that come into the vehi-
cle from the outside through the heating
and air conditioning system. If dust or
other pollutants accumulate in the filter
over a period of time, the air flow from the
air vents may decrease, resulting in
moisture accumulation on the inside of
the windshield even when the outside
(fresh) air position is selected. If this hap-
pens, have the climate control air filter
replaced by an authorized HYUNDAI
dealer.
✽ ✽
NOTICE
• Replace the filter according to the
Maintenance Schedule.
If the vehicle is being driven in severe
conditions such as dusty, rough roads,
more frequent climate control air fil-
ter inspections and changes are
required.
• When the air flow rate suddenly
decreases, the system should be
checked at an authorized HYUNDAI
dealer.
Checking the amount of air con-
ditioner refrigerant and compres-
sor lubricant
When the amount of refrigerant is low,
the performance of the air conditioning is
reduced. Overfilling also has a negative
influence on the air conditioning 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.OMG075033

position. In N(Neutral) position, you
can not start the vehicle.
4. Depress the brake pedal.
5. Press the HEV system start/stop button.
WARNING
Except in an emergency, never
press the engine start/stop but-
ton while the vehicle is in motion.
This could result in higher brak-
ing effort and steering, which
could cause an accident.
Before leaving the driver’s seat,
always make sure the shift lever
is engaged in P (Park), set the
parking brake fully and shut the
engine off. Unexpected and sud-
den vehicle movement may occur
if these precautions are not
taken.
Never reach for the engine
start/stop button, or any other
controls through the steering
wheel while the vehicle is in
motion. The presence of your
hand or arm in this area could
cause a loss of vehicle control,
an accident and serious bodily
injury or death.
Do not place any movable objects
around the driver’s seat as they
may move while driving, interfere
with the driver and lead to an
accident.WARNING
Always wear appropriate shoes
when operating your vehicle.
Unsuitable shoes (high heels, ski
boots, etc.) may interfere with your
ability to use the brake and acceler-
ator pedal.
Even if you depress the brake pedal
before starting the vehicle in a
sloped area, the vehicle may move
when the parking brake is released.
For your safety, release the parking
brake after starting the vehicle.

Driving your vehicle
In the event of brake failure
If service brakes fail to operate while the
vehicle is in motion, you can make an
emergency stop with the parking brake.
The stopping distance, however, will be
much greater than normal.
✽ ✽
NOTICE
1) When you apply the brake repeatedly,
you may hear the sound the electric
hydraulic pump or motor operating.
This is a normal condition.
2) The following types of pedal applica-
tions may result in the brake pedal
feeling different, however it is normal
condition.
- When you apply the pedal quickly
- When you apply the pedal continu-
ously and repeatedly
- While braking, when the ABS oper-
ated
(Continued)
Wet brakes may impair the vehi-
cle’s ability to safely slow down;
the vehicle may also pull to one
side when the brakes are applied.
Applying the brakes lightly will
indicate whether they have been
affected in this way. Always test
your brakes in this fashion after
driving through deep water. To
dry the brakes, apply them lightly
while maintaining a safe forward
speed until brake performance
returns to normal.
Always, confirm the position of
the brake and accelerator pedal
before driving. If you don't check
the position of the accelerator
and brake pedal before driving,
you may depress the accelerator
instead of the brake pedal. It may
cause a serious accident.
Do not turn off the Hybrid system
while going down a hill. The brake
booster may not work sufficiently
and the braking distance may be
longer.
(Continued)(Continued)
If the brake pedal does not return
to its normal position when
released, there may be a malfunc-
tion in the brake system. Take
your vehicle to an authorized
HYUNDAI dealer and have the
system checked.
To avoid applying the brakes do
not get too close to the vehicle in
front of you and try to avoid
going down steep roads or sharp
corning if the power assisted
brakes are not functioning nor-
mally. The vehicle will stop but
the braking distance may be
longer.
WARNING- Parking brake
Applying the parking brake while
the vehicle is moving at normal
speeds can cause a sudden loss of
control of the vehicle. If you must
use the parking brake to stop the
vehicle, use great caution in apply-
ing the brake.
CAUTION
If the driver’s door is not firmly
closed, the auxiliary battery may be
discharged because the brake con-
troller remains in standby opera-
tion. To prevent the battery from
being discharged, ensure the door
is fully closed.

517
Driving your vehicle
If the parking brake does not release or
does not release all the way, have the
system checked by an authorized
HYUNDAI dealer.
Check the brake warning light by pressing
the engine start/stop button ON (do not
start the engine). This light will be illumi-
nated when the parking brake is applied
with the engine start/stop button in the
START or ON position.
Also, the brake warning light may illumi-
nate for a second even though the park-
ing brake is released at the moment the
engine start/stop button is pressed to the
ON position.
Before driving, be sure the parking brake
is fully released and the brake warning
light is off.
If the brake warning light remains on after
the parking brake is released while the
hybrid system is in READY state, there
may be a malfunction in the brake sys-
tem. Immediate attention is necessary.If at all possible, cease driving the vehicle
immediately. If that is not possible, use
extreme caution while operating the vehi-
cle and only continue to drive the vehicle
until you can reach a safe location or
repair shop.
WARNING
To prevent unintentional move-
ment when stopped and leaving
the vehicle, do not use the
gearshift lever in place of the
parking brake. Set the parking
brake AND make sure the
gearshift lever is securely posi-
tioned in P (Park) for automatic
transaxle equipped vehicles.
Never allow anyone who is unfa-
miliar with the vehicle to touch
the parking brake. If the parking
brake is released unintentionally,
serious injury may occur.
All vehicles should always have
the parking brake fully engaged
when parking to avoid inadver-
tent movement of the vehicle
which can injure occupants or
pedestrians.

WARNING
It is normal for the brake warning
light to illuminate temporarily
when the brake is depressed
repeatedly and go out after a few
seconds when the brake is no
longer depressed. However, if the
brake warning light turns on, this
may be a sign of a malfunctioning
brake system and could cause
the braking distance to increase.
Have your system checked if the
brake warning light remains on. A
malfunctioning brake system
could result in a vehicle accident
and serious injury or death.
