Starting the Vehicle
Information
• The vehicle will start by pressing the
Engine Start/Stop button, only when
the smart key is in the vehicle.
• Even if the smart key is in the vehi-
cle, if it is far away from the driver,
the vehicle may not start.
• When the Engine Start/Stop button
is in the ACC or ON position, if any
door is open, the system checks for
the smart key. If the smart key is not
in the vehicle, the " " indicator
will blink and the warning "Key not
in vehicle" will come on and if all
doors are closed, the chime will also
sound for about 5 seconds. Keep the
smart key in the vehicle when in the
ACC position or if the vehicle is in
the ready ( ) mode.1. Always carry the smart key with
you.
2. Make sure the parking brake is
applied.
3. Make sure the shift lever is in P
(Park).
4. Depress the brake pedal.
5. Press the Engine Start/Stop but-
ton. If the vehicle starts, the " "
indicator will come on.
Information
• Do not wait for the engine to warm
up while the vehicle remains station-
ary. Start driving at moderate
engine speeds. (Aggressive accelerat-
ing and decelerating should be
avoided.)
• Always start the vehicle with your
foot on the brake pedal. Do not
depress the accelerator while start-
ing the vehicle. Do not rev the
engine while warming it up.

Always wear appropriate shoes
when operating your vehicle.
Unsuitable shoes, such as
high heels, ski boots, sandals,
flip-flops, etc., may interfere
with your ability to use the
brake and accelerator pedals.
Do not start the vehicle with the
accelerator pedal depressed.
The vehicle can move and lead
to an accident.
Wait until the engine rpm is
normal. The vehicle may sud-
denly move if the brake pedal
is released when the rpm is
high.
WARNING

5-10
Driving your vehicle
To prevent damage to the vehicle:
If the " " indicator turns off
while you are in motion, do not
attempt to shift to the P (Park)
position.
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 vehicle.To prevent damage to the vehicle:
When the stop lamp switch 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
vehicle 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 switch
fuse is blown.
For your safety always depress
the brake pedal before starting the
vehicle.

But it differs from a conventional
automatic transmission because it
does not incorporate a torque con-
verter. 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 vibra-
tion can be felt as the transmission
shaft speed is matched with the
engine shaft speed. This is a nor-
mal 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 launch-
ing the vehicle from a stop or when
traveling at low, stop-and-go vehi-
cle 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 cor-
rect gear. This is a normal condi-
tion. 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 accelera-
tor pedal quickly, you may feel
engine braking before the trans-
mission 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 vehicle 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 acceler-
ating at low speed. During this
break-in period, the shift quality
and performance of your new vehi-
cle is continuously optimized.To reduce the risk of serious
injury or death:
ALWAYS check the surround-
ing 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 Engine
Start/Stop button in the OFF
position. Unexpected and
sudden vehicle movement
can occur if these precautions
are not followed.
Do not use aggressive engine
braking (shifting from a high-
er 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 exces-
sively.
When the clutch temperatures are
too high, the "Transmission temp is
high! Stop safely" warning mes-
sage will appear on the LCD dis-
play, a chime will sound, and the
transmission shifting 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),
and allow the transmission to cool.
If you ignore this warning, the driv-
ing condition may become worse.
You may experience abrupt shifts,
frequent shifts, or jerkiness.
When the message "Trans cooled.
Resume driving." appears you can
continue to drive your vehicle.
When possible, drive the vehicle
smoothly.
Transmission Overheated
If the vehicle continues to be driv-
en and the clutch temperatures
reach the maximum temperature
limit, the "Transmission Hot! Park
with engine on" warning will be dis-
played. 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.
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),
and allow the transmission to cool.
When the message "Trans cooled.
Resume driving." appears you can
continue to drive your vehicle.
When possible, drive the vehicle
smoothly.
If any of the warning messages in
the LCD display continue to blink, for
your safety, contact an authorized
HYUNDAI dealer and have the sys-
tem checked.
Shift Lever Position
P (Park)
Always come to a complete stop
before shifting into P (Park).
To shift from P (Park), you must depr
ess firmly on the brake pedal and
make sure your foot is off the accel-
erator pedal.
If you have done all of the above
and still cannot shift the lever out
of P (Park), see "Shift-Lock
Release" in this section.
The shift lever must be in P (Park)
before turning the vehicle off.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
lever is in P (Park), apply the
parking brake, and turn the
vehicle off.
When parking on an incline,
place the shift lever in Park
and apply the parking brake to
prevent the vehicle from
rolling downhill.
Do not use the P (Park) posi-
tion in place of the parking
brake.
