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

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

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.

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.

✽
✽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.

Hill-start assist control (HAC)
(if equipped)
A vehicle has the tendency to slip back
on a steep hill when it starts to go after
stopping. The Hill-start Assist Control
(HAC) prevents the vehicle from slipping
back by operating the brakes automati-
cally for about 2 seconds. The brakes are
released when the accelerator pedal is
depressed or after about 2 seconds.
✽ ✽ NOTICE
• The HAC does not operate when the
transaxle shift lever is in the P (Park)
or N (Neutral) position.
• The HAC activates even though the ESC is off but it does not activate
when the ESC has malfunctioned.

Hazard warning flasher
The hazard warning flasher serves as a
warning to other drivers to exercise
extreme caution when approaching,
overtaking, or passing your vehicle.It should be used whenever emergency
repairs are being made or when the vehi-
cle is stopped near the edge of a road-
way.
Depress the flasher switch with the
engine start/stop button in any position.
The flasher switch is located in the cen-
ter console switch panel. All turn signal
lights will flash simultaneously.
• The hazard warning flasher operates
whether your vehicle is running or not.
The turn signals do not work when the hazard flasher is on.
Care must be taken when using the hazard warning flasher while the vehi-
cle is being towed.
If the vehicle stalls at a crossroad
or crossing
If the vehicle stalls at a crossroad or
crossing, set the shift lever in the N
(Neutral) position and then push the vehi-
cle to a safe place.
If you have a flat tire while driving
If a tire goes flat while you are driving:
1. Take your foot off the accelerator pedaland let the car slow down while driving
straight ahead. Do not apply the brakes
immediately or attempt to pull off the
road as this may cause a loss of con-
trol. When the car has slowed to such
a speed that it is safe to do so, brake
carefully and pull off the road. Drive off
the road as far as possible and park on
firm, level ground. If you are on a divid-
ed highway, do not park in the median
area between the two traffic lanes.
