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

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.

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.
WARNING

5-16
Driving your vehicle
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.
