ic converter damage is possible
which could result in loss of
engine power.
In this case, we recommend that
you have the vehicle inspected by
an authorized HYUNDAI dealer as
soon as possible.
- Diesel Engine
If the Malfunction Indicator Lamp
(MIL) blinks, error related to the
injection quantity adjustment may
have occurred which could result
in loss of engine power, combus-
tion noise and poor emission.
In this case, we recommend that
you have the engine control sys-
tem inspected by an authorized
HYUNDAI dealer.Charging System Warning Light
This warning light illuminates:
When there is a malfunction with
either the alternator or electrical
charging system.
If there is a malfunction with either
the alternator or electrical charging
system:
1. Drive carefully to the nearest safe location and stop your vehicle.
2. Turn the engine off and check the alternator drive belt for looseness
or breakage.

Engine Oil PressureWarning Light
This warning light illuminates:
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.
Low Fuel LevelWarning Light
This warning light illuminates:
When the fuel tank is nearly empty.
Add fuel as soon as possible.
Driving with the Low Fuel Level
warning light on or with the fuel

Driving your vehicleAs 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 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 vehi-
cle may not be smooth when accel-
erating 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 ignition
switch in the LOCK/OFF posi-
tion. 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.
