- It remains on until the engine is
started.
• When the engine oil pressure is low.
If the engine oil pressure is low:
1. Drive carefully to the nearest safe
location and stop your vehicle.
2. Turn the engine off and check the
engine oil level (For more details,
refer to “Engine Oil” in chapter 7).
If the level is low, add oil as required.
If the warning light remains on
after adding oil or if oil is not avail-
able, we recommend that you
have the vehicle inspected by an
authorized HYUNDAI dealer as
soon as possible.• If the engine does not stop
immediately after the Engine Oil
Pressure Warning Light is illumi-
nated, severe damage could
result.
• If the warning light stays on
while the engine is running, it
indicates that there may be seri-
ous engine damage or malfunc-
tion. In this case,
1. Stop the vehicle as soon as it
is safe to do so.
2. Turn off the engine and check
the oil level. If the oil level is
low, fill the engine oil to the
proper level.
3. Start the engine again. If the
warning light stays on after the
engine is started, turn the
engine off immediately. In this
case, we recommend that you
have the vehicle inspected by
an authorized HYUNDAI dealer.

Exhaust System (DPF)
Warning Light (for
diesel engine)
This warning light illuminates:
• When there is a malfunction with
Diesel Particulate Filter (DPF) sys-
tem.
• When this warning light illumi-
nates, it may turn off after driving
the vehicle:
- at more than 60 km/h (37 mph), or
- at more than 2nd gear with 1500
~ 2000 engine rpm for a certain
time (for about 25 minutes).
If this warning light blinks in spite of
the procedure (at this time LCD
warning message will be displayed),
we recommend that you have the
DPF system checked by an author-
ized HYUNDAI dealer.
If you continue to drive with the
DPF warning light blinking for a
long time, the DPF system can be
damaged and fuel consumption
can worsen.

Engine Start/Stop Button in the ON
position.
- The engine can be started after
the glow indicator light goes off.
- The illumination time varies with
the engine coolant temperature,
air temperature, and battery con-
dition.
If the indicator light remains on or
blinks after the engine has warmed
up or while driving, there may a mal-
function with the engine preheating
system.
In this case, we recommend that you
have the vehicle inspected by an
authorized HYUNDAI dealer.
Information
If the engine does not start within 10
seconds after the preheating is com-
pleted, set the ignition switch or
Engine Start/Stop Button to the
LOCK or OFF position for 10 seconds
and then to the ON position in order
to preheat the engine again.

• The dual clutch transmission gives
the driving feel of a manual trans-
mission, yet provides the ease of a
fully automatic transmission. Unlike
a traditional automatic transmis-
sion, the gear shifting can some-
times be felt and heard on the dual
clutch transmission, as the actua-
tors engage the clutch and the
gear is selected.
The dual clutch transmission can
be thought of as an automatically
shifting manual transmission.
When D (Drive) is selected, the
transmission will automatically shift
through the gears similar to a con-
ventional automatic transmission.• The dual clutch transmission incor-
porates a dry-type dual clutch
mechanism, which allows for better
acceleration performance and
increased fuel efficiency while driv-
ing. But it differs from a conven-
tional automatic transmission in
that it does not incorporate a
torque converter. Instead, the tran-
sition 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 launch-
ing the vehicle from a stop or when
traveling at low, stop-and-go vehi-
cle speeds.
Driving your vehicle
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 ignition
switch in the LOCK/OFF posi-
tion. Unexpected and sudden
vehicle movement can occur
if these precautions are not
followed.

•Do not use the engine brake
(shifting from a high gear to
lower gear) rapidly on slip-
pery roads. The vehicle may
slip causing an accident.
