Before Entering the Vehicle
• Be sure all windows, outside mirror(s), and outside lights are clean and
unobstructed.
• Remove frost, snow, or ice.
• Visually check the tires for uneven wear and damage.
• Check under the vehicle for any sign of leaks.
• Be sure there are no obstacles behind you if you intend to back up.
Before Starting
• Make sure the hood, the trunk, and the doors are securely closed and
locked.
• Adjust the position of the seat and steering wheel.
• Adjust the inside and side view mirrors.
• Verify all the lights work.
• Fasten your seatbelt. Check that all passengers have fastened their
seatbelts.
• Check the gauges and indicators in the instrument panel and the
messages on the instrument display
when the ignition switch is in the ON
position.
• Check that any items you are carrying are stored properly or fastened down
securely.
WARNING
To reduce the risk of SERIOUS INJURY or
DEATH, take the following precautions:
• ALWAYS wear your seat belt. All
passengers must be properly belted
whenever the vehicle is moving.
For more information, refer to "Seat
Belts" in chapter 3.
• Always drive defensively. Assume
other drivers or pedestrians may be
careless and make mistakes.
• Stay focused on the task of driving.
Driver distraction can cause
accidents.
• Leave plenty of space between you
and the vehicle in front of you.
WARNING
NEVER drink alcohol or take drugs and
drive.
Drinking alcohol or taking drugs and
driving is dangerous and may result in
an accident and SERIOUS INJURY or
DEATH.
Drunk driving is the number one
contributor to the highway death
toll each year. Even a small amount
of alcohol will affect your reflexes,
perceptions and judgment. Just
one drink can reduce your ability to
respond to changing conditions and
emergencies and your reaction time
gets worse with each additional drink.
Driving while under the influence
of drugs is as dangerous or more
dangerous than driving under the
influence of alcohol.
You are much more likely to have a
serious accident if you drink or take
drugs and drive. If you are drinking or
taking drugs, don't drive. Do not ride
with a driver who has been drinking
or taking drugs. Choose a designated
driver or call a taxi.
BEFORE DRIVING

While Driving6-14
Transmission ranges
The indicator in the instrument cluster
displays the gear position when the
ignition switch is in the ON position.
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 gear 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.
• If equipped, do not use the engine
brake (shifting from a high gear to
lower gear using the paddle shifters)
rapidly on slippery roads.
P (Park)
Always come to a complete stop before
shifting in
to P (Park).
To shift from P (Park), you must depress
firmly on the brake pedal and make sure
your foot is off the accelerator pedal.
The gear must be in P (Park) before
turning the engine off.
WARNING
• Shifting into P (Park) while the
vehicle is in motion may cause you to
lose control of the vehicle.
• After the vehicle has stopped, always
make sure the gear is in P (Park),
apply the parking brake, and turn
the engine off.
• Do not use the P (Park) position in
place of the parking brake.
R (Reverse)
Use this position to drive the vehicle
backw

ard.
NOTICE
Always come to a complete stop before
shifting into or out of R (Reverse); you
may damage the transmission if you
shift into R (Reverse) while the vehicle is
in motion.
When the vehicle is stopped in
R (Reverse) 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 R (Reverse) position, if you open
the driver's door with the seat belt
unfastened, the gear may be not shifted
to P (Park) position automatically for
protecting the automatic transmission.
N (Neutral)
The wheels and transmission are not

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.

While Driving6-18
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.
• 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 t ravel lanes.
• HYUNDAI recommends you follow all
posted speed limits.
