Introduction
For customers who do not use TOP
Tier Detergent Gasoline regularly,
and have problems starting or the
engine does not run smoothly, deter-
gent-based fuel additives that you
can purchase separately may be
added to the gasoline. If TOP TIER
Detergent Gasoline is not available,
one bottle of additive added to the
fuel tank at every 7,500 miles or 12
months is recommended.
Additives are available from your
authorized HYUNDAI dealer along
with information on how to use them.
Do not mix other additives.
Operation in foreign countries
If you are going to drive your vehicle
in another country, be sure to:
Observe all regulations regarding registration and insurance.
Determine that acceptable fuel is available. This vehicle should not be modi-
fied. Modification of your vehicle
could affect its performance, safety
or durability and may even violate
governmental safety and emis-
sions regulations.
In addition, damage or perform-
ance problems resulting from any
modification may not be covered
under warranty.
If you use unauthorized electronic devices, it may cause the vehicle to
operate abnormally, wire damage,
battery discharge and fire. For your
safety, do not use unauthorized
electronic devices. By following a few simple precautions
for the first 600 miles (1,000 km) you
may add to the performance, econo-
my and life of your vehicle.
Do not race the engine.
While driving, keep your engine
speed (rpm, or revolutions per
minute) between 2,000 rpm and
4,000 rpm.
Do not maintain a single speed for long periods of time, either fast or
slow. Varying engine speed is need-
ed to properly break-in the engine.
Avoid hard stops, except in emer- gencies, to allow the brakes to seat
properly.

The Rear Parking Assist System
may not operate normally when:
Moisture is frozen to the sensor.
The sensor is covered with dirt or
debris such as snow or ice, or the
sensor cover is blocked.
There is a possibility of the Rear
Parking Assist System malfunction
when:
Driving on uneven road surfacessuch as unpaved roads, gravel,
bumps, or gradient.
Objects generating excessive noise such as vehicle horns, loud motor-
cycle engines, or truck air brakes
can interfere with the sensor.
Heavy rain or water spray is present.
Wireless transmitters or mobile phones are present near the sensor.
The sensor is covered with snow.
Any non-factory equipment or accessories have been installed, or
if the vehicle bumper height or sen-
sor installation has been modified.

Types of warning soundIndicator
When an object is approximately 24 to 47 in (60 to 120
cm) from the rear bumper, the warning sound beeps inter-
mittently.
When an object is approximately 12 to 24 in (30 to 60 cm)
from the rear bumper, the warning sound beeps more fre-
quently.
When an object is within 12 in (30 cm) from the rear
bumper, the warning sound beeps continuously.
The indicator may differ from the illustration as objects or sensors sta-tus. If the indicator blinks, have your vehicle checked by an authorized
HYUNDAI dealer.

Driving your vehicle
Always come to a complete stop before shifting into D (Drive) or
R (Reverse).
Do not put the shift lever in N (Neutral) while driving.
To avoid damage to your trans- mission, do not try to accelerate
in R (Reverse) or any forward
gear position with the brakes
applied.
When stopped on a slope, do not hold the vehicle with accel-
erator pedal. Use the brake
pedal or the parking brake.
DCT Warning Messages
Steep Grade
This warning message is displayed
when vehicle is driven slowly on a
grade and the vehicle detects that
the brake pedal is not applied.
Driving up hills or on steep grades:
To hold the vehicle on an inclineuse the foot brake or the parking
brake.
When in stop-and-go traffic on an incline, allow a gap to form ahead
of you before moving the vehicle
forward. Then hold the vehicle on
the incline with the foot brake. If the vehicle is held or creeping
forward on an incline by applying
the accelerator pedal, the clutch
and transmission may overheat
which can result in damage. At this
time, a warning message will
appear on the LCD display.
If the LCD display warning is active, the foot brake must be
applied.
Ignoring the warnings can lead to damage to the transmission.
To hold the vehicle on a hill use
the foot brake or the parking
brake. If the vehicle is held by
applying the accelerator pedal on
a hill, the clutch and transmission
will be overheated resulting in
damage.

Transmission High Temperature
Under certain conditions, such asrepeated 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.

5-20
Driving your vehicle
The system changes from manual mode to automatic mode when
- the vehicle speed is lower than 3mph (5 km/h),
- you depress the accelerator pedal for more than 5 seconds,
- you pull the [+] paddle shifter for more than 1 second, or
- you move the shift lever from D (Drive) to S (Sport) or manual
shift mode (+, -) and then back to
D (Drive).
Information
If the [+] and [-] paddle shifters are
pulled at the same time, gear shift may
not occur.
Parking
Always come to a complete stop and
continue to depress the brake pedal.
Move the shift lever into the P (Park)
position, apply the parking brake,
and place the Engine Start/Stop but-
ton in the OFF position. Take the key
with you when exiting the vehicle.
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.
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.
Depressing both accelerator and brake pedals at the same time can
trigger logic for engine power
reduction to assure vehicle decel-
eration. Vehicle acceleration will
resume after the brake pedal is
released.
i
When you stay in the vehicle
with the engine running, be
careful not to depress the accel-
erator 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 flam-
mable materials, such as dry
grass, paper or leaves. They
may ignite and cause a fire.
