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

What to do in an emergency
With Tire Mobility Kit
(TMK, if equipped) - Type A
For safe operation, carefully read
and follow the instructions in this
manual before use.
(1) Compressor
(2) Sealant bottle
The Tire Mobility Kit is a temporary fix
to the tire and the tire should be
inspected by an authorized HYUNDAI
dealer as soon as possible.
Introduction
With the Tire Mobility Kit you stay
mobile even after experiencing a tire
puncture.
The compressor and sealing com-
pound system effectively and com-
fortably seals most punctures in a
passenger car tire caused by nails
or similar objects and reinflates the
tire.
After you ensure that the tire is prop-
erly sealed you can drive cautiously
on the tire (distance up to 120 miles
(200 km)) at a max. speed of (50
mph (80 km/h)) in order to reach a
service station or tire dealer for the
tire replacement.

OLF067015
One sealant bottle for one tire
When two or more tires are flat,
do not use the tire mobility kit
because the supported one
sealant of Tire Mobility Kit is
only used for one flat tire.
CAUTION
Tire wall
Do not use the Tire Mobility Kit
to repair punctures in the tire
walls. This can result in an acci-
dent due to tire failure.
WARNING
Temporary fix
Have your tire repaired as soon
as possible. The tire may lose
air pressure at any time after
inflating with the Tire Mobility
Kit.
