WARNING
Carbon monoxide (CO) gas is toxic. Breathing CO can cause unconsciousness and
death.
Engine exhaust contains carbon monoxide which cannot be seen or smelled.
Do not inhale engine exhaust.
If at any time you smell engine exhaust inside the vehicle, open the windows
immediately. Exposure to CO can cause unconsciousness and death by asphyxiation.
Be sure the exhaust system does not leak.
The exhaust system should be checked whenever the vehicle is raised to change the
oil or for any other purpose. If you hear a change in the sound of the exhaust or if you
drive over something that strikes the underneath side of the vehicle, have the exhaust
system be checked as soon as possible by an authorized HYUNDAI dealer.
Do not run the engine in an enclosed area.
Letting the engine idle in your garage, even with the garage door open, is a hazardous
practice. Run the engine only long enough to start the engine and to move the vehicle
out of the garage.
Avoid idling the engine for prolonged periods with people inside the vehicle.
If it is necessary to idle the engine for a prolonged period with people inside the
vehicle, be sure to do so only in an open area with the air intake set at “Fresh” and fan
control set to high so fresh air is drawn into the interior.
Keep the air intakes clear.
To assure proper operation of the ventilation system, keep the ventilation air intakes
located in front of the windshield clear of snow, ice, leaves, or other obstructions.
If you must drive with the liftgate open:
Close all windows.
Open instrument panel air vents.
Set the air intake control at “Fresh”, the air flow control at “Floor” or “Face”, and the fan
control set to high.

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 button
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.

[ When using the paddle shifter
(manual shift mode), do not use
engine braking (shifting from a
high gear to lower gear) rapidly on
slippery roads. The vehicle may slip
causing an accident.
P (Park)
Always come to a complete stop before
shifting into 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 shift button 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 shift button is in P
(Park), apply the parking brake, and
turn the engine off.

[ When parking on an incline, shift
the gear to P (Park) and apply the
parking brake to prevent the vehicle
from rolling downhill.

[ Do not use the P (Park) position in
place of the parking brake.
R (Reverse)
Use this position to drive the vehicle
backward.
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) or 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 R
(Reverse) or D (Drive) 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.

Driving your vehicle6-22
The manual shift mode also changes
back to automatic shift mode in one of
following situations - When the accelerator pedal is gently depressed for more than 6 seconds
while driving
- When the vehicle stops
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 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 shift the gear to N (Neutral)
when driving. If the gear is shifted to
N (Neutral) while driving, the vehicle
loses the ability to provide engine
braking. Doing so may increase the
risk of an accident.
Also, shifting the gear back to
D (Drive) while the vehicle is
moving may severely damage the
transmission.

[ When driving uphill or downhill,
always shift to D (Drive) for driving
forward or shift to R (Reverse) for
driving rearwards. After selecting
D (Drive) or R (Reverse), check the
gear position indicated on the cluster
before driving. If the vehicle moves in
the opposite direction of the selected
gear, the engine may turn off and a
serious accident might occur due to
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.

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

always make sure the shift button
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 button in N
(Neutral) while driving.
