Automatic reverse
OTM050053
During power opening or closing if the
power liftgate senses any obstacle, the
power liftgate will stop and move in the
opposite direction.
The auto reverse function may not work
if objects are too soft or thin, or if the
liftgate is almost fully closed near the
latched position.
Caution should be taken to prevent any
objects from obstructing the liftgate
opening.
If the automatic reverse feature operates
more than two times while attempting
to open or close the liftgate, the power
liftgate may stop at that position.
WARNING
Never intentionally place any object
or part of your body in the path of
the power liftgate to make sure the
automatic reverse function operates.
NOTICE
Do not put heavy objects on the power
liftgate before you operate the power
liftgate. Additional weight may damage
the operation of the system.
Non-operating conditions of the
power liftgate
• The power liftgate does not open
when the vehicle is in motion.
The chime will sound if you drive with
the liftgate opened. Stop your vehicle
immediately at a safe place and check
if your liftgate is opened.
• Operating the power liftgate more
than 5 times continuously could
cause damage to the operating motor.
If this occurs, the power liftgate
system enters into thermal protection
mode to prevent the motor from
overheating. In thermal protection
mode, the power liftgate will not
operate. If any of the power liftgate
buttons are pressed to try to open the
liftgate, the chime will sound 3 times
but the liftgate will not operate.

The manual shift mode also changes
back to automatic shift mode in one of
following situations
- When the accelera
tor pedal is gently
depressed for more than 6 seconds
while driving
- When the vehicle s

tops
Information
If the [+] and [-] paddle shifters are pulled
at the same time, gear shift may not occur.
Good driving practices
• Never move the shift button from
P (Park) or N (Neutral) to any other
position with the accelerator pedal
depressed.
• Never move the shift lever/button into
P (Park) when the vehicle is in motion.
Be sure the vehicle is completely
stopped before you attempt to shift
into R (Reverse) or D (Drive).
• Do not move the shift button to N
(Neutral) when driving. Doing so
may result in an accident because
of a loss of engine braking and the
transmission could be damaged.
• Driving uphill or downhill, Shift
to D (Drive) to drive forward or R
(Reverse) to drive backwards, and
check the gear position indicated
on the cluster before driving. If you
drive in the opposite direction of the
selected gear, the engine will turn
off and a serious accident might be
occurred due to the degraded brake
performance.
• Do not drive with your foot resting
on the brake pedal. Even light, but
consistent pedal pressure can result
in the brakes overheating, brake wear
and possibly even brake failure.
• When driving with shifter paddles,
slow down before shifting to a lower
gear. Otherwise, the lower gear may
not be engaged if the engine rpms are
outside of the allowable range.
• Always apply the parking brake when
leaving the vehicle. Do not depend on
placing the transmission in P (Park) to
keep the vehicle from moving.

and possibly even brake failure.
• Always apply the parking brake when
leaving the vehicle. Do not depend on
placing the transmission in P (Park) to
keep the vehicle from moving.
• Exercise extreme caution when
driving on a slippery surface. Be
especially careful when braking,
accelerating or shifting gears. On a
slippery surface, an abrupt change
in vehicle speed can cause the drive
wheels to lose traction and may cause
loss of vehicle control resulting in an
accident.
• Optimum vehicle performance and
economy is obtained by smoothly
depressing and releasing the
accelerator. WARNING
To reduce the risk of SERIOUS INJURY
or DEATH:
• ALWAYS wear your seatbelt. In a
collision, an unbelted occupant
is significantly more likely to be
seriously injured or killed than a
properly belted occupant.
• Avoid high speeds when cornering or
turning.
• Do not make quick steering wheel
movements, such as sharp lane
changes or fast, sharp turns.
• The risk of rollover is greatly
increased if you lose control of your
vehicle at highway speeds.
• Loss of control often occurs if two or
more wheels drop off the roadway
and the driver over steers to reenter
the roadway.
• In the event your vehicle leaves
the roadway, do not steer sharply.
Instead, slow down before pulling
back into the travel lanes.
• HYUNDAI recommends you follow all
posted speed limits.

Good braking practices
WARNING
Whenever leaving the vehicle or
parking, always come to a complete
stop and continue to depress the brake
pedal. Shift the gear to the P (Park)
position, then apply the parking brake,
and press the Engine Start/Stop button
to the 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. If the braking action does not
return to normal, stop as soon as it is safe
to do so and we recommend that you
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.
