D (Drive)
This is the normal driving position. The
transmission will automatically shift
through a 8-gear sequence, providing
the best fuel economy and power.
To start the vehicle forward, push the D
(Drive) button by depressing the brake
pedal with the engine ON. Then depress
the accelerator pedal smoothly.
For extra power when passing another
vehicle or driving uphill, depress the
accelerator fully. The transmission will
automatically downshift to the next
lower gear (or gears, as appropriate).
When the vehicle is stopped in D (Drive)
position, if you open the driver's door
with the seat belt unfastened, the gear is
shifted to P (Park) position automatically.
However when the vehicle moves in D
(Drive) position, if you open the driver's
door with the seat belt unfastened, the
gear may not shift to P (Park) position
automatically to protect the automatic
transmission.
Shift-lock system
For your safety, the automatic
transmission has a shift-lock system
which prevents shifting the gear from
P (Park) or N (Neutral) to R (Reverse)
or D (Drive) unless the brake pedal is
depressed.
To shift the gear from P (Park) or N
(Neutral) to R (Reverse) or D (Drive):
1.
Depr
ess and hold the brake pedal.
2.

S
tart the engine or place the ignition
switch in the ON position.
3.

EPB (Electronic Parking Brake) may be
automatically applied when:
• Requested by other systems
• The driver turns the engine off while
Auto Hold is operating.
• The vehicle is parked on the slope and
the Engine Start/Stop button is in the
OFF position.
• The Engine is turned off when the
driver tries to park but the vehicle still
moves a bit.
Warning messages
OAEE056115L
To release EPB, fasten seatbelt, close
door, hood and trunk
• If you try to drive with the EPB
applied, a warning will sound and a
message will appear.
• If the driver's seat belt is unfastened
and the engine hood or trunk is
opened, a warning will sound and a
message will appear.
• If there is a problem with the vehicle,
a warning may sound and a message
may appear.
If the situation occurs, depress the brake
pedal and release EPB by pressing the
EPB switch.
WARNING
• Whenever leaving the vehicle or
parking, always come to a complete
stop and continue to depress the
brake pedal.
Shift the gear in

to the P (Park)
position, press the EPB switch, and
set the ignition switch to the OFF
position. Take the Key with you when
exiting the vehicle.
V

ehicles not fully engaged in P (Park)
with the parking brake set are at risk
for moving inadvertently and causing
injury to yourself or others.
• NEVER allow anyone who is
unfamiliar with the vehicle to touch
the EPB switch. If the EPB is released
unintentionally, serious injury may
occur.
• Only release the EPB when you are
seated inside the vehicle with your
foot firmly on the brake pedal.
NOTICE
• Do not apply the accelerator pedal
while the parking brake is engaged.
If you depress the accelerator pedal
with the EPB engaged, a warning will
sound and a message will appear.
Damage to the parking brake may
occur.
• Driving with the parking brake on
can overheat the braking system and
cause premature wear or damage
to brake parts. Make sure the EPB
is released and the Parking Brake
Warning Light is off before driving.
While Driving

WARNING
If ESC indicator light () or EPS
warning light () stays on or blinks,
your vehicle may have a malfunction
with the VSM system. When the
warning light illuminates, have your
vehicle checked by an authorized
HYUNDAI dealer as soon as possible.
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 tires and wheels
installed.
Hill-Start Assist Control (HAC)
The Hill-Start Assist Control (HAC)
helps prevent the vehicle from rolling
backwards when starting a vehicle from
a stop on a hill. The system operates the
brakes automatically for approximately
2 seconds and releases the brake after 2
seconds or when the accelerator pedal is
depressed.
WARNING
Always be ready to depress the
accelerator pedal when starting off on
a incline. The HAC activates only for
approximately 2 seconds.
NOTICE
• The HAC does not operate when
the shift button is in P (Park) or N
(Neutral)
• The HAC activates even though the
ESC (Electronic Stability Control) is
off but does not activate when the
ESC has malfunctioned.
Good Braking Practices
WARNING
Whenever leaving the vehicle or
parking, always come to a complete
stop and continue to depress the brake
pedal. Move the shift button into P
(Park) position, then apply the parking
brake, and place the ignition switch in
the LOCK/OFF position.
Vehicles parked with the parking brake
not applied or not fully engaged may
roll inadvertently and may cause injury
to the driver and others. ALWAYS apply
the parking brake before exiting the
vehicle.
Wet brakes can be dangerous! The
brakes may get wet if the vehicle is
driven through standing water or if it
is washed. Your vehicle will not stop as
quickly if the brakes are wet. Wet brakes
may cause the vehicle to pull to one side.
To dry the brakes, apply the brakes
lightly until the braking action returns to
normal, taking care to keep the vehicle
under control at all times. If the braking
action does not return to normal, stop
as soon as it is safe to do so and call
an authorized HYUNDAI dealer for
assistance.
DO NOT drive with your foot resting on
the brake pedal. Even light, but constant
pedal pressure can result in the brakes
overheating, brake wear, and possibly
even brake failure.
If a tire goes flat while you are driving,
apply the brakes gently and keep the
vehicle pointed straight ahead while you
slow down. When you are moving slowly
enough for it to be safe to do so, pull off
the road and stop in a safe location.
Keep your foot firmly on the brake pedal
when the vehicle is stopped to prevent
the vehicle from rolling forward.
