For smooth operation, depress the brake
pedal when shifting from N (Neutral) to a
forward or reverse gear.Transaxle ranges
The indicator in the instrument cluster
displays the shift lever position when the
engine start/stop button is in the ON
position.
P (Park)
Always come to a complete stop before
shifting into P (Park). This position locks
the transaxle and prevents the drive
wheels from rotating.
WARNING- Automatic
transaxle
Always check the surrounding
areas near your vehicle for peo-
ple, especially children, before
shifting a car 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 fully and
shut the HEV system off.
Unexpected and sudden vehicle
movement can occur if these pre-
cautions are not followed in the
order identified.
CAUTION
To avoid damage to your
transaxle, do not accelerate the
engine in R (Reverse) or any for-
ward gear position with the
brakes on.
When stopped on an incline, do
not hold the vehicle stationary
with engine power. Use the serv-
ice brake or the parking brake.
WARNING
Shifting into P (Park) while the vehi-
cle is in motion will cause the drive
wheels to lock which will cause you
to lose control of the vehicle.
Do not use the P (Park) position
in place of the parking brake.
Always make sure the shift lever
is latched in the P (Park) position
and set the parking brake fully.
Never leave a child unattended in
a vehicle.
CAUTION
The transaxle may be damaged if
you shift into P (Park) while the

NOTICE
• In sports mode, the driver must exe-
cute upshifts in accordance with road
conditions.
• In sports mode, only the 6 forward
gears can be selected. To reverse or
park the vehicle, move the shift lever
to the R (Reverse) or P (Park) position
as required.
• In sports mode, downshifts are made
automatically when the vehicle slows
down. When the vehicle stops, 1st gear
is automatically selected.
• In sports mode, when the engine rpm
approaches the red zone, the transaxle
will upshift automatically.
• To maintain the required levels of vehi-
cle performance and safety, the system
may not execute certain gearshifts
when the shift lever is operated.
• When driving on a slippery road, push
the shift lever forward into the +(up)
position. This causes the transaxle to
shift into the 2nd gear which is better
for smooth driving on a slippery road.
Push the shift lever to the -(down) side
to shift back to the 1st gear.
Shift lock system
For your safety, the automatic transaxle
has a shift lock system which prevents
shifting the transaxle from P (Park) into R
(Reverse) unless the brake pedal is
depressed.
To shift the transaxle from P (Park) into R
(Reverse):
1. Depress and hold the brake pedal.
2. Start the engine or turn the engine
start/stop button to the ON position.
3. Move the shift lever.
If the brake pedal is repeatedly
depressed and released with the shift
lever in the P (Park) position, a chattering
noise near the shift lever may be heard.
This is a normal condition.Shift-lock override
If the shift lever cannot be moved from
the P (Park) position into R (Reverse)
position with the brake pedal depressed,
continue depressing the brake, then do
the following:
1. Carefully remove the cap (1) covering
the shift-lock access hole.
2. Insert a key (or screwdriver) into the
access hole and press down on the
key (or screwdriver).
3. Move the shift lever.
4. Have your vehicle inspected by an
authorized HYUNDAI dealer immedi-
ately.
WARNING
Always fully depress the brake
pedal before and while shifting out
of the P (Park) position into anoth-
er position to avoid inadvertent
motion of the vehicle which could
injure persons in or around the car.

Driving your vehicle
Good driving practices
Never move the gear shift lever from P
(Park) or N (Neutral) to any other posi-
tion with the accelerator pedal
depressed.
Never move the gear shift lever into P
(Park) when the vehicle is in motion.
Be sure the car is completely stopped
before you attempt to shift into R
(Reverse) or D (Drive).
Never take the car out of gear and
coast down a hill. This may be
extremely hazardous. Always leave the
car in gear when moving.
Do not "ride" the brakes. This can
cause them to overheat and malfunc-
tion. Instead, when you are driving
down a long hill, slow down and shift to
a lower gear. When you do this, engine
braking will help slow the car.
Slow down before shifting to a lower
gear. Otherwise, the lower gear may
not be engaged.
Always use the parking brake when
parked. Do not depend on placing the
transaxle in P (Park) to keep the car
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 the vehicle to go out of control.
Optimum vehicle performance and
economy is obtained by smoothly
depressing and releasing the accelera-
tor pedal.WARNING
Always buckle-up! In a collision,
an unbelted occupant is signifi-
cantly more likely to be seriously
injured or killed than a properly
belted occupant.
Avoid high speeds when corner-
ing 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.
In the event your vehicle leaves
the roadway, do not steer sharply.
Instead, slow down before pulling
back into the travel lanes.
Never exceed posted speed lim-
its.

517
Driving your vehicle
If the parking brake does not release or
does not release all the way, have the
system checked by an authorized
HYUNDAI dealer.
Check the brake warning light by turning
the engine start/stop button ON (do not
start the engine). This light will be illumi-
nated when the parking brake is applied
with the engine start/stop button in the
START or ON position.
Also, the brake warning light may illumi-
nate for a second even though the park-
ing brake is released at the moment the
engine start/stop button is turned to the
ON position.
Before driving, be sure the parking brake
is fully released and the brake warning
light is off.
If the brake warning light remains on after
the parking brake is released while the
hybrid system is in READY state, there
may be a malfunction in the brake sys-
tem. Immediate attention is necessary.If at all possible, cease driving the vehicle
immediately. If that is not possible, use
extreme caution while operating the vehi-
cle and only continue to drive the vehicle
until you can reach a safe location or
repair shop.
WARNING
To prevent unintentional move-
ment when stopped and leaving
the vehicle, do not use the
gearshift lever in place of the
parking brake. Set the parking
brake AND make sure the
gearshift lever is securely posi-
tioned in P (Park) for automatic
transaxle equipped vehicles.
Never allow anyone who is unfa-
miliar with the vehicle to touch
the parking brake. If the parking
brake is released unintentionally,
serious injury may occur.
All vehicles should always have
the parking brake fully engaged
when parking to avoid inadver-
tent movement of the vehicle
which can injure occupants or
pedestrians.
W-75
WARNING
It is normal for the brake warning
light to illuminate temporarily
when the brake is depressed
repeatedly and go out after a few
seconds when the brake is not
depressed. But the braking dis-
tance might be longer when the
brake pedal is depressed while
the brake warning light is on.
Have your system checked if the
brake warning light is on. It may
lead to an accident.

Anti-lock brake system (ABS)
The ABS continuously senses the speed
of the wheels. If the wheels are going to
lock, the ABS system repeatedly modu-
lates the hydraulic brake pressure to the
wheels.
When you apply your brakes under con-
ditions which may lock the wheels, you
may hear a “tik-tik’’ sound from the
brakes, or feel a corresponding sensation
in the brake pedal. This is normal and it
means your ABS is active.
In order to obtain the maximum benefit
from your ABS in an emergency situa-
tion, do not attempt to modulate your
brake pressure and do not try to pump
your brakes. Press your brake pedal as
hard as possible or as hard as the situa-
tion warrants and allow the ABS to con-
trol the force being delivered to the
brakes.
✽ ✽
NOTICE
A click sound may be heard in the
engine compartment when the vehicle
begins to move after the engine is start-
ed. These conditions are normal and
indicate that the anti-lock brake system
is functioning properly.
Even with the anti-lock brake system,
your vehicle still requires sufficient
stopping distance. Always maintain a
safe distance from the vehicle in front
of you.
Always slow down when cornering.
The anti-lock brake system cannot pre-
vent accidents resulting from exces-
sive speeds.
On loose or uneven road surfaces,
operation of the anti-lock brake system
may result in a longer stopping dis-
tance than for vehicles equipped with a
conventional brake system.
WARNING
ABS (or ESC) will not prevent acci-
dents due to improper or danger-
ous driving maneuvers. Even
though vehicle control is improved
during emergency braking, always
maintain a safe distance between
you and objects ahead. Vehicle
speeds should always be reduced
during extreme road conditions.
The braking distance for cars
equipped with an anti-lock braking
system (or Electronic Stability
Control system) may be longer than
for those without it in the following
road conditions.
During these conditions the vehicle
should be driven at reduced
speeds:
Rough, gravel or snow-covered
roads.
With tire chains installed.
(Continued)
(Continued)
On roads where the road surface
is pitted or has different surface
height.
The safety features of an ABS (or
ESC) equipped vehicle should not
be tested by high speed driving or
cornering. This could endanger the
safety of yourself or others.

Driving your vehicle
✽ ✽
NOTICE
When you jump start your vehicle
because of a drained battery, the engine
may not run as smoothly and the ABS
warning light may turn on at the same
time. This happens because of the low
battery voltage. It does not mean your
ABS is malfunctioning.
• Do not pump your brakes!
• Have the battery recharged before
driving the vehicle.
Electronic stability control (ESC)
The Electronic Stability control (ESC)
system is designed to stabilize the vehicle
during cornering maneuvers. ESC checks
where you are steering and where the
vehicle is actually going. ESC applies the
brakes at individual wheels and
intervenes in the engine management
system to stabilize the vehicle.
W-78
CAUTION
If the ABS warning light is on and
stays on, you may have a problem
with the ABS. In this case, howev-
er, your regular brakes will work
normally.
The ABS warning light will stay on
for approximately 3 seconds after
the engine start/stop button is ON.
During that time, the ABS will go
through self-diagnosis and the
light will go off if everything is nor-
mal. If the light stays on, you may
have a problem with your ABS.
Contact an authorized HYUNDAI
dealer as soon as possible.
CAUTION
When you drive on a road having
poor traction, such as an icy road,
and operate your brakes continu-
ously, the ABS will be active con-
tinuously and the ABS warning
light may illuminate. Pull your car
over to a safe place and stop the
engine.
Restart the engine. If the ABS
warning light is off, then your
ABS system is normal.
Otherwise, you may have a prob-
lem with the ABS. Contact an
authorized HYUNDAI dealer as
soon as possible.

The Electronic Stability Control (ESC)
system is an electronic system designed
to help the driver maintain vehicle control
under adverse conditions. It is not a
substitute for safe driving practices.
Factors including speed, road conditions
and driver steering input can all affect
whether ESC will be effective in
preventing a loss of control. It is still your
responsibility to drive and corner at
reasonable speeds and to leave a
sufficient margin of safety.
When you apply your brakes under con-
ditions which may lock the wheels, you
may hear a “tik-tik’’ sound from the
brakes, or feel a corresponding sensation
in the brake pedal. This is normal and it
means your ESC is active.
✽ ✽
NOTICE
A click sound may be heard in the
engine compartment when the vehicle
begins to move after the engine is start-
ed. These conditions are normal and
indicate that the Electronic Stability
Control System is functioning properly.
ESC operation
ESC ON condition

ON, ESC and ESC OFF indi-
cator lights illuminate for
approximately 3 seconds,
then ESC is turned on.

for at least half a second after
turning the ignition ON to turn
ESC off. (ESC OFF indicator
will illuminate). To turn the
ESC on, press the ESC OFF
button (ESC OFF indicator
light will go off).

you may hear a slight ticking
sound. This is the ESC per-
forming an automatic system
self-check and does not indi-
cate a problem.WARNING
Never drive too fast for the road
conditions or too quickly when cor-
nering. Electronic stability control
(ESC) will not prevent accidents.
Excessive speed in turns, abrupt
maneuvers and hydroplaning on
wet surfaces can still result in seri-
ous accidents. Only a safe and
attentive driver can prevent acci-
dents by avoiding maneuvers that
cause the vehicle to lose traction.
Even with ESC installed, always fol-
low all the normal precautions for
driving - including driving at safe
speeds for the conditions.
