Shift-lock system
For your safety, the automatic
transmission has a shift-lock system
which prevents shifting the transmission
from P (Park) into R (Reverse) unless the
brake pedal is depressed.
To shift the transmission from P (Park)
into R (Reverse):
1. Depress and hold the brake pedal.
2. Start the engine or place the ignition
switch in the ON position.
3. Move the shift lever
Ignition key interlock system
The ignition key cannot be removed
unless the shift lever is in the P (Park)
position.

Good Driving Practices
• Never move the shift lever from P
(Park) or N (Neutral) to any other
position with the accelerator pedal
depressed.
• Never move the shift lever 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 lever 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 the vehicle
is moving in the opposite direction
of the selected gear, the engine may
stop and a serious accident may
occur. Never attempt to select a gear
that is opposite to the direction of
the vehicle motion. Stop the vehicle
before changing to the desired gear.
• 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.• 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.

WARNING
To reduce the risk of serious injury or
death:
• ALWAYS check the surrounding
areas near your vehicle for people,
especially children, before shifting a
vehicle into D (Drive) or R (Reverse).
• Before leaving the driver’s seat,
always make sure the shift lever
is in the P (Park) position, then set
the parking brake, and place the
ignition switch in the LOCK/OFF
position. Unexpected and sudden
vehicle movement can occur if these
precautions are not followed.
• Do not use aggressive engine braking
(shifting from a higher gear to a
lower gear) on slippery roads. This
could cause the tires to slip and may
result in an accident.
NOTICE
• Always come to a complete stop
before shifting into D (Drive) or R
(Reverse).
• Do not put the shift lever in N
(Neutral) while driving.
WARNING
Due to transmission failure, you may
not continue to drive and the position
indicator and the position indicator (D,
P) on the instrument cluster will blink.
Contact authorized HYUNDAI dealer
and have the system checked.

Steep grade! Press brake pedal
Driving up hills or on steep grades:
• To hold the vehicle on an incline use
the foot brake or the parking brake.
• When in stop-and-go traffic on an
incline, allow a gap to form ahead
of you before moving the vehicle
forward. Then hold the vehicle on the
incline with the foot brake.
• If the vehicle is held or creeping
forward on an incline by applying
the accelerator pedal, the clutch and
transmission may overheat which
can result in damage. At this time, a
warning message will appear on the
