Driving your vehicle
Starting and stopping the engine for
turbocharger intercooler
1. Do not race or accelerate the engine
immediately after starting the engine.
If the engine is cold, idle for several
seconds before sufficient lubrication is
ensured in the turbo charger unit.
2. After high speed or extended driving
that requires heavy engine load, idle
the engine about one minute before
turning the engine off. This idle time
will allow the turbocharger to cool
prior to shutting the engine off.
NOTICE
Do not turn off the engine immediately
after it has been subjected to a heavy
load. Doing so may cause severe
damage to the engine or turbo charger
unit.
NOTICE
To prevent damage to the vehicle:
• If traffic and road conditions permit,
you may put the shift lever in the N
(Neutral) position while the vehicle
is still moving and press the Engine
Start/Stop button in an attempt to
restart the engine.
• Do not push or tow your vehicle to
start the engine.
NOTICE
To prevent damage to the vehicle:
When the stop lamp fuse is blown, you
can’t start the engine normally. Replace
the fuse with a new one. If you are not
able to replace the fuse, you can start
the engine by pressing and holding
the Engine Start/Stop button for 10
seconds with the Engine Start/Stop
button in the ACC position.
Do not press the Engine Start/Stop
button for more than 10 seconds except
when the stop lamp fuse is blown.

Driving your vehicle
Using the clutch (if equipped)
The clutch pedal should be depressed all
the way to the floor before:
- Starting the engine
The engine will not start without
depressing the clutch pedal.
- Shifting
To start your vehicle, slowly release
the clutch pedal and depress the
accelerator.
When releasing the clutch pedal, release
it slowly. The clutch pedal should always
be released while driving.
NOTICE
To prevent unnecessary wear or
damage to the clutch:
• Do not rest your foot on the clutch
pedal while driving.
• Do not hold the vehicle with the
clutch on an incline, while waiting for
the traffic light, etc.
• Always depress the clutch pedal
down fully to prevent noise or
damage.
• Do not start with the 2nd (second)
gear engaged except when you start
on a slippery road.
• Depress the clutch pedal all the way
and be careful not to depress the
pedal again before returning to the
upright position after you release
the pedal. If you depress the pedal
before returning to the original
position repeatedly, it may cause the
clutch system failure.
Downshifting
Downshift when you must slow down in
heavy traffic or drive up a steep hill to
prevent engine load.
Also, downshifting reduces the chance
of stalling and can accelerate when you
need to increase your speed again.
When the vehicle is going downhill,
downshifting helps maintain safe speed
by providing brake power from the
engine and enables less wear on the
brakes.
NOTICE
To prevent damage to the engine,
clutch and transmission:
• When downshifting from 5th
gear to 4th gear, be careful not to
inadvertently push the shift lever
sideways engaging the 2nd gear.
A drastic downshift may cause the
engine speed to increase to the point
the tachometer will enter the red-
zone.
• Do not downshift more than two
gear at a time or downshift the gear
when the engine is running at high
speed (5,000 RPM or higher). Such
a downshifting may damage the
engine, clutch and the transmission.

Good driving practices
• Never take the vehicle out of gear and
coast down a hill. This is extremely
dangerous.
• Don’t “ride” the brakes. This can
cause the brakes and related parts to
overheat and malfunction.
When you are driving down a long hill,
slow down and shift to a lower gear.
Engine braking will help slow down
the vehicle.
• Slow down before shifting to a lower
gear. This will help avoid over-revving
the engine, which can cause damage.
• Slow down when you encounter cross
winds. This gives you much better
control of your vehicle.
• Be sure the vehicle is completely
stopped before you shift into R
(Reverse) to prevent damage to the
transmission.
• 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.
WARNING
Do not use the engine brake (shifting
from a higher gear to lower gear)
rapidly on slippery roads. The vehicle
may slip causing an accident.
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.

CAUTION
• When downshifting from fifth gear
to fourth gear, caution should be
taken not to inadvertently press the
shift lever sideways in such a manner
that the second gear is engaged.
Such a drastic downshift may cause
the engine speed to increase to the
point that the tachometer will enter
the red-zone. Such overrevving of
the engine and transmission may
possibly cause engine damage.
• Do not downshift more than 2 gears
or downshift the gear when the
engine is running at high speed
(5,000 RPM or higher). Such a
downshifting may damage the
engine, clutch and the transmission.
• During cold weather, shifting may
be difficult until the transmission
lubricant is warmed up. This is
normal and not harmful to the
transmission.
• If you’ve come to a complete stop
and it’s hard to shift into 1st or
R(Reverse), leave the shift lever at
N(Neutral) position. Then shift into
1st or R(Reverse) gear position.
• Do not use the shift lever as a
handrest during driving, as this can
result in premature wear of the
transmission shift forks.
• To prevent possible damage to the
clutch system, do not start with the
2nd (second) gear engaged except
when you start on a slippery road.
WARNING
• Before leaving the driver’s seat,
always set the parking brake fully
and shut the engine off. Then make
sure the transmission is shifted into
1st gear when the vehicle is parked
on a level or uphill grade, and shifted
into R (Reverse) on a downhill
grade. Unexpected and sudden
vehicle movement can occur if these
precautions are not followed in the
order identified.
• Do not use the engine brake (shifting
from a high gear to lower gear)
rapidly on slippery roads. The vehicle
may slip causing an accident.
Downshifting
When you must slow down in heavy
traffic or while driving up steep hills,
downshift before the engine starts to
labor. Downshifting reduces the chance
of stalling and gives better acceleration
when you again need to increase your
speed. When the vehicle is traveling
down steep hills, downshifting helps
maintain safe speed and prolongs brake
life.

Driving your vehicle
Good driving practices
• Never take the vehicle out of gear and
coast down a hill. This is extremely
hazardous. Always leave the vehicle
in gear.
• Don’t “ride” the brakes. This can cause
them to overheat and malfunction.
Instead, when you are driving down a
long hill, shift to a lower gear. When
you do this, engine braking will help
slow down the vehicle.
• Slow down before shifting to a lower
gear. This will help avoid over-revving
the engine, which can cause damage.
• Slow down when you encounter cross
winds. This gives you much better
control of your vehicle.
• Be sure the vehicle is completely
stopped before you attempt to shift
into reverse. The transmission can be
damaged if you do not.
• 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 the vehicle to go out of control.
WARNING
• Always buckle-up! 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 oversteers 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.
• Never exceed posted speed limits.

7-22
Driving your vehicle
• The dual clutch transmission
incorporates a dry-type dual clutch
mechanism, which allows for better
acceleration performance and
increased fuel efficiency while 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 1,500 km (1000 miles),
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 tires to slip and may result
in an accident.

Transmission high temperature
• Under certain conditions, such as
repeated stop-and-go launches on
steep grades, sudden take off or
acceleration, or other harsh driving
conditions, the transmission clutch
temperatures will increase excessively.
• When the clutch is overheated, the
safe protection mode engages and the
gear position indicator on the cluster
blinks with a chime. At this time,
“Transmission temp. is high! Stop
safely” warning message will appear
on the LCD display and driving may
not be smooth.
• If this occurs, pull over to a safe
location, stop the vehicle with the
engine running, apply the brakes
and shift the vehicle to P (Park) with
engine on, and allow the transmission
to cool.
• If you ignore this warning, the driving
condition may become worse. You
may experience abrupt shifts, frequent
shifts, or jerkiness. To return to the
normal driving condition, stop the
vehicle and apply the foot brake or
shift into P (Park). Then allow the
transmission to cool for a few minutes
with engine on, before driving off.
• When possible, drive the vehicle
smoothly.

Transmission overheated
• If the vehicle continues to be driven
and the clutch temperatures reach
the maximum temperature limit, the
“Trans Hot! Park with engine on”
warning will be displayed. When this
occurs the clutch is disabled until the
clutch cools to normal temperatures.
• The warning will display a time to wait
for the transmission to cool.
