Introduction
For customers who do not use TOP
Tier Detergent Gasoline regularly,
and have problems starting or the
engine does not run smoothly, addi-
tives that you can buy separately
may be added to the gasoline. If TOP
TIER Detergent Gasoline is not avail-
able, 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. No special break-in period is needed.
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.

Parking Brake & BrakeFluid Warning Light
This warning light illuminates:
Once you set the ignition switch or
the Engine Start/Stop button to the
ON position.
- It illuminates for approximately 3seconds.
- It remains on if the parking brake is applied.
When the parking brake is applied.
When the brake fluid level in the reservoir is low.
- If the warning light illuminateswith the parking brake released, it
indicates the brake fluid level in
reservoir is low.
If the brake fluid level in the reser-
voir is low:
1. Drive carefully to the nearest safe location and stop your vehicle.
2. With the engine stopped, check the brake fluid level immediately and
add fluid as required (For more
information, refer to "Brake
Fluid" in chapter 7) . Then check all
brake components for fluid leaks. If
any leak on the brake system is still
found, the warning light remains on,
or the brakes do not operate prop-
erly, do not drive the vehicle. In this
case, have your vehicle inspected
by an authorized HYUNDAI dealer.
Dual-diagonal braking system
Your vehicle is equipped with dual-
diagonal braking systems. This
means you still have braking on two
wheels even if one of the dual sys-
tems should fail.
With only one of the dual systems
working, more than normal pedal
travel and greater pedal pressure are
required to stop the vehicle.
Also, the vehicle will not stop in as
short a distance with only a portion
of the brake system working.
If the brakes fail while you are driv-
ing, shift to a lower gear for addition-
al engine braking and stop the vehi-
cle as soon as it is safe to do so.

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

5-21
Driving your vehicle
(Continued)
Under certain conditions suchas repeated launch on steep
grades, the clutch in the trans-
mission could overheat. When
the clutch is overheated, the
safe protection mode engages. If
the safe protection mode
engages, the gear position indi-
cator on the cluster blinks with a
chime sound. At this time, a
warning message will appear on
the LCD display and driving may
not be smooth.
(Continued)(Continued)
If you ignore this warning, the
driving condition may become
worse. To return the normal driv-
ing condition, stop the vehicle
and apply the foot brake for a
few minutes before driving off.
Repetitive kick downs may lead to overheating of the transmis-
sion. This will lead to change in
the vehicle speed shift pattern,
and illuminate some warning
message.
To return the normal driving
condition, refrain from kick
down speed changes. When the
warning message illuminates,
park the vehicle at a safe loca-
tion.
If the ecoshift dual clutch trans- mission starts to become over-
heated, the gear shift character-
istics may change. Gear shifts
may become more abrupt. If
continued operation includes
frequent and continuous
upshifts and downshifts, the
overheat warning message on
the cluster LCD display may illu-
minate.
(Continued)(Continued)
If this occurs, stop the vehicle,
apply the brakes or shift the
vehicle to P (Park), and allow the
transmission to cool with engine
on.
When possible, continue to
drive the vehicle smoothly while
trying to avoid frequent upshift-
ing and downshifting.
Gear shifts may be more notice- able than a conventional auto-
matic transmission. This is a
normal characteristic of this
type of Ecoshift dual clutch
transmission.
During the first 1000 miles, you may feel that the vehicle may not
be smooth when accelerating at
low speed. During this break-in
period, the shift quality and per-
formance of your new vehicle is
continuously optimized.
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.

Driving your vehicle
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 ignition switch in the
LOCK/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. When driving in Manual shift mode,
slow down before shifting to a
lower gear. Otherwise, the lower
gear may not be engaged if the
engine rpms are outside of the
allowable range.
Always apply the parking brake when leaving the vehicle. Do not
depend on placing the transmis-
sion in P (Park) to keep the vehicle
from moving.
Exercise extreme caution when driving on a slippery surface. Be
especially careful when braking,
accelerating or shifting gears. On a
slippery surface, an abrupt change
in vehicle speed can cause the
drive wheels to lose traction and
may cause loss of vehicle control
resulting in an accident.
Optimum vehicle performance and economy is obtained by smoothly
depressing and releasing the
accelerator.
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.
