INTRODUCTION
Congratulations, and thank you for choosing HYUNDAI. We are pleased to welcome you to the growing number of
discriminating people who drive HYUNDAIS. We are very proud of the advanced engineering and high-quality
construction of each HYUNDAI we build.
Your Owner's Manual will introduce you to the features and operation of your new HYUNDAI. To become familiar with
your new HYUNDAI, so that you can fully enjoy it, read this Owner's Manual carefully before driving your new vehicle.
This manual contains important safety information and instructions intended to familiarize you with your vehicle's
controls and safety features so you can safely operate your vehicle.
This manual also contains information on maintenance designed to enhance safe operation of the vehicle. It is

Driving your vehicle The Ecoshift dual clutch transmis-sion gives the driving feel of a man-
ual transmission, yet provides the
ease of a fully automatic transmis-
sion. Unlike a traditional automatic
transmission, the gear shifting can
be felt (and heard) on the Ecoshift
dual clutch transmission.
- Think of it as an automaticallyshifting manual transmission.
- Shift into Drive range and get fully automatic shifting, similar to a
conventional automatic transmis-
sion. Ecoshift dual clutch transmission
adopts dry-type dual clutch, which
is different from torque converter of
automatic transmission, and shows
better acceleration performance
during driving. But, initial launch
might be little bit slower than
Automatic Transmission.
The dry-type clutch transfers torque and provides a direct drive
feeling which may feel different
from a conventional automatic
transmission with a torque convert-
er. This may be more noticeable
when starting from a stop or low
vehicle speed.
When rapidly accelerating at lower vehicle speeds, the engine could
rev up to higher engine RPM
depending on the driving condition.
For smooth uphill launches, press down the accelerator pedal
smoothly depending on the current
conditions.
If you release your foot from the accelerator pedal at low vehicle
speed, you may feel strong engine
brake, which is similar to manual
transmission.5
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 engine braking
(shifting from a high gear to
lower gear) rapidly on slip-
pery roads. The vehicle may
slip causing an accident.
WARNING
To avoid damage to your
transaxle, do not try to accel-
erate in R (Reverse) or any for-
ward gear position with the
brakes on.
When stopped on slope, do
not hold the vehicle with
accelerator pedal. Use the
service brake or the parking
brake.
CAUTION

Information - Kickdown
Mechanism
Use the kickdown mechanism for
maximum acceleration. Depress the
accelerator pedal beyond the pressure
point. The automatic transmission will
shift to a lower gear depending on the
engine speed.
Moving up a steep grade from a standing start
To move up a steep grade from a
standing start, depress the brake
pedal, shift the shift lever to D
(Drive). Depress the accelerator
gradually while releasing the service
brakes.
i
To reduce the risk of SERIOUS
INJURY or DEATH:
ALWAYS wear your seatbelt.
In a collision, an unbelted
occupant is significantly more
likely to be seriously injured
or killed than a properly belt-
ed occupant.
Avoid high speeds when cor-
nering or turning.
Do not make quick steering
wheel movements, such as
sharp lane changes or fast,
sharp turns.
The risk of rollover is greatly
increased if you lose control
of your vehicle at highway
speeds.
Loss of control often occurs if
two or more wheels drop off
the roadway and the driver
over steers to reenter the
roadway.
(Continued)
(Continued)
In the event your vehicle
leaves the roadway, do not
steer sharply. Instead, slow
down before pulling back into
the travel lanes.
HYUNDAI recommends you
follow all posted speed limits.
WARNING
If your vehicle becomes stuck in
snow, mud, sand, etc., then you
may attempt to rock the vehicle
free by moving it forward and
backward. Do not attempt this
procedure if people or objects
are anywhere near the vehicle.
During the rocking operation
the vehicle may suddenly move
forward or backward as it
becomes unstuck, causing
injury or damage to nearby peo-
ple or objects.
WARNING

When towing your vehicle in an
emergency without wheel dollies :
1. Place the ignition switch in theACC position.
2. Place the shift lever in N (Neutral).
3. Release the parking brake.Emergency Towing
(if equipped)
If towing is necessary, we recom-
mend you to have it done by an
authorized HYUNDAI dealer or a
commercial tow truck service. If towing service is not available in an
emergency, your vehicle may be
temporarily towed using a cable or
chain secured to the emergency tow-
ing hook at the rear of the vehicle.
Use extreme caution when towing
the vehicle with a cable or chain. A
driver must be in the vehicle to steer
it and operate the brakes.
Towing in this manner may be done
only on hard-surfaced roads for a
short distance and at low speeds.
Also, the wheels, axles, power train,
steering and brakes must all be in
good condition.
Failure to place the transmis-
sion shift lever in N (Neutral)
may cause internal damage to
the transmission.
