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. Depress and hold the brake pedal.
2. Start the engine or place the ignition switch in the ON position.
3. Depress the brake pedal and push the R (Reverse) or D (Drive) button. Stay in N (Neutral) position when engine is Off
ODN8069006
ODN8069008
If you want to keep the N (Neutral)
position after the engine is OFF, do the
following.
1. Deactivate the AUTO HOLD and release the parking brake when the
ignition switch is ON.
2. Start the engine. Push the N (neutral) button while depressing the brake
pedal. If the message ("Press and
hold OK button to stay in Neutral
when vehicle is OFF") appears on the
cluster LCD display, press and hold
the OK button on the steering wheel
for more than 1 second.
3. When the message ("Vehicle will stay in (N). Change gear to cancel")
appears on the cluster LCD display,
turn off the engine.
In this situation, if you unfasten the
driver's seat belt and open the driver's
door within 3 minutes, the gear stays in
the N (Neutral) position and the ignition
switch is turned off.

Good Driving Practices
• Never shift the gear from P (Park) or
N (Neutral) to any other position with
the accelerator pedal depressed.
• Never shift the gear 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 shift the gear 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.
• While driving up or downhill, check
the gear position, indicated on the
cluster, to ensure the vehicle is
driving forward while in D (Drive), or
backward while in R (Reverse). If you
drive in the opposite direction of the
selected gear, the engine will turn off
and a serious accident may occur 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 in the manual shift
mode, 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.
Information
Kickdown Mechanism (if equipped)
If you depress the accelerator pedal equipped with Kickdown device beyond
the pressure point, it maximizes the engine
power. You may feel when the Kickdown
equipment starts to work and hear the sound of Kickdown operation. It is normal
operation, not a failure.
