AUTO (Automatic) control
(if equipped)
The rain sensor located at the top of the
windscreen glass senses the amount of
rainfall and controls the wiping cycle for
the proper interval. The wiper operation
time will be automatically controlled,
depending on rainfall.
When the rain stops, the wiper stops. To
vary the speed setting, turn the speed
control knob.
If the wiper switch is set in AUTO mode
when the ignition switch is in the ON
position, the wiper will operate once to
perform a self-check of the system. Set
the wiper to the OFF position when the
wiper is not in use.
WARNING
To avoid personal injury from the
windscreen wipers, when the engine
is running and the windscreen wiper
switch is placed in the AUTO mode:
Do not touch the upper end of the
windscreen glass facing the rain sensor.
Do not wipe the top of the windscreen
glass with a damp or wet cloth.
Do not put pressure on the windscreen
glass.
NOTICE
When washing the vehicle, set the
ZLSHUVZLWFKLQWKH2))SRVLWLRQWRVWRS
the auto wiper operation. The wiper
may operate and be damaged if the
switch is set in the AUTO mode whilst
washing the vehicle.
Do not remove the sensor cover
located at the top of the passenger side
windscreen glass. Damage to system
parts could occur and may not be
covered by your vehicle warranty.
Windscreen washers
OTLE045168
In the OFF (O) position, pull the lever
gently toward you to spray washer
fluid on the windscreen and to run the
wipers 1-3 cycles. The spray and wiper
operation will continue until you release
the lever. If the washer does not work,
you may need to add washer fluid to the
washer fluid reservoir.
WARNING
When the outside temperature is
below freezing, ALWAYS warm the
windscreen using the defroster to
prevent the washer fluid from freezing
on the windscreen and obscuring your
vision which could result in an accident
and serious injury or death.

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, we recommend
that the exhaust system be checked as soon as possible by a HYUNDAI authorised
repairer.
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 windscreen clear of snow, ice, leaves, or other obstructions.
If you must drive with the tailgate 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.

Move the shift lever into the P (Park)
position, apply the parking brake, and
place the ignition switch in the LOCK/
OFF position. Take the Key with you
when exiting the vehicle.
WARNING
When you stay in the vehicle with
the engine running, be careful not to
depress the accelerator pedal for a long
period of time. The engine or exhaust
system may overheat and start a fire.
The exhaust gas and the exhaust
system are very hot. Keep away from
the exhaust system components.
Do not stop or park over flammable
materials, such as dry grass, paper or
leaves. They may ignite and cause a
fire.
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, always shift
to D (Drive) when driving forward or to
R (Reverse) when driving 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 in 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.

[The dual clutch transmission
incorporates a dry-type dual clutch
mechanism, which allows for better
acceleration performance and
increased fuel efficiency whilst driving.
But it differs from a conventional
automatic transmission because
it does not incorporate a torque
converter. Instead, the transition from
one gear to the next is managed by
clutch slip, especially at lower speeds.
As a result, shifts are sometimes more
noticeable, and a light vibration can be
felt as the transmission shaft speed is
matched with the engine shaft speed.
This is a normal condition of the dual
clutch transmission.

[The dry-type clutch transfers torque
more directly and provides a direct-
drive feeling which may feel different
from a conventional automatic
transmission. This may be more
noticeable when launching the vehicle
from a stop or when traveling at low,
stop-and-go vehicle speeds.

[When rapidly accelerating from a
lower vehicle speed, the engine
rpm may increase dramatically as a
result of clutch slip as the dual clutch
transmission selects the correct gear.
This is a normal condition.

[When accelerating from a stop on an
incline, press the accelerator smoothly
and gradually to avoid any shudder
feeling or jerkiness.

[When traveling at a lower vehicle
speed, if you release the accelerator
pedal quickly, you may feel engine
braking before the transmission
changes gears. This engine braking
feeling is similar to operating a manual
transmission at low speed.

[When driving downhill, you may
wish to move the gear shift lever to
Manual Shift mode and downshift to
a lower gear in order to control your
speed without using the brake pedal
excessively.
[When you turn the engine on and off,
you may hear clicking sounds as the
system goes through a self-test. This
is a normal sound for the dual clutch
transmission.

[During the first 1000 miles (1,500 km),
you may feel that the vehicle may not
be smooth when accelerating at low
speed. During this break-in period, the
shift quality and performance of your
new vehicle is continuously optimized.
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 tyres to slip and may result
in an accident.
