ESC OFF usage
When driving
• ESC should be turned on for daily
driving whenever possible.
• To turn ESC off while driving, press
the ESC OFF button while driving
on a flat road surface.
✽NOTICE
• When operating the vehicle on a
dynamometer, ensure that the
ESC is turned off (ESC OFF light
illuminated and the buzzer beeps)
by pressing the button for 3 sec-
onds. If the ESC is left on, it may
prevent the vehicle speed from
increasing, and result in false diag-
nosis.
• Turning the ESC off does not
affect ABS or brake system opera-
tion. CAUTION
Driving with varying tire or
wheel sizes may cause the ESC
system to malfunction. When
replacing tires, make sure they
are the same size as your origi-
nal tires.
WARNING
The Electronic Stability Control
is only a driving aid; use pre-
cautions for safe driving by
slowing down on curved,
snowy, or icy roads. Drive slow-
ly and don’t attempt to acceler-
ate whenever the ESC indicator
light is blinking, or when the
road surface is slippery.
WARNING
Never press the ESC OFF but-
ton while ESC is operating (ESC
indicator light blinks).
If ESC is turned off while ESC is
operating, the vehicle may slip
out of control.
CAUTION
Even if you cancel the ESC
function by pressing the button,
the ESC function may be operat-
ed. It is normal condition for
safety driving.

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 operat-
ing the brakes automatically for
about 2 seconds. The brakes are
released when the accelerator pedal
is depressed or after about 2 sec-
onds.
✽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 acti-
vate when the ESC has malfunc-
tioned.
Emergency Stop Signal (ESS)
(if equipped)
The Emergency Stop Signal system
alerts the driver behind by blinking
the stop light when the vehicle is
braked rapidly and severely.
The system is activated when:
• The vehicle suddenly stops (vehi-
cle speed is over 55km/h and the
vehicle deceleration at greater
than 7 m/s
2)
• The ABS is activating
When the vehicle speed is under 40
km/h and the ABS deactivates or the
sudden stop situation is over, the
stop light blinking will stop. Instead,
the hazard warning flasher will turn
on automatically.
The hazard warning flasher will turn
off when vehicle speed is over
10km/h after the vehicle has
stopped. Also, it will turn off when the
vehicle is driven at low speed for
some time. You can turn it off manu-
ally by pushing the hazard warning
flasher switch.
WARNING
The HAC is activated only for
about 2 seconds, so when the
vehicle is starting off always
depress the accelerator pedal.

Good braking practices• Check to be sure the parking brake
is not engaged and that the park-
ing brake indicator light is out
before driving away.
• Driving through water may get the
brakes wet. They can also get wet
when the vehicle is washed. Wet
brakes can be dangerous! Your car
will not stop as quickly if the brakes
are wet. Wet brakes may cause the
vehicle to pull to one side.
To dry the brakes, apply the brakes
lightly until the braking action
returns to normal, taking care to
keep the car under control at all
times. If the braking action does
not return to normal, stop as soon
as it is safe to do so and call an
authorized HYUNDAI dealer for
assistance.CAUTION
The Emergency Stop Signal
(ESS) system will not work if the
hazard warning flasher is
already on.WARNING
• Whenever leaving vehicle or
parking, always set the park-
ing brake and fully engage the
vehicle's transmission into
the P (Park) position. Vehicles
not fully engaged in park with
the parking brake set are at
risk for moving inadvertently
and injuring yourself or oth-
ers.
• All vehicles should always
have the parking brake fully
engaged when parking to
avoid inadvertent movement
of the vehicle which can injure
occupants or pedestrians.

543
Driving your vehicle
• Don't coast down hills with the
vehicle out of gear. This is extreme-
ly hazardous. Keep the car in gear
at all times, use the brakes to slow
down, then shift to a lower gear so
that engine braking will help you
maintain a safe speed.
• Don't "ride" the brake pedal.
Resting your foot on the brake
pedal while driving can be danger-
ous because it can result in the
brakes overheating and losing their
effectiveness. It also increases the
wear of the brake components.
• If a tire goes flat while you are driv-
ing, apply the brakes gently and
keep the car pointed straight
ahead while you slow down. When
you are moving slowly enough for it
to be safe to do so, pull off the road
and stop in a safe place.• If your vehicle is equipped with an
automatic transmission, don't let
your car creep forward. To avoid
creeping forward, keep your foot
firmly on the brake pedal when the
car is stopped.
• Be caution when parking on a hill.
Firmly engage the parking brake
and place the shift lever in P. If your
vehicle is facing downhill, turn the
front wheels into the curb to help
keep the vehicle from rolling. If
your vehicle is facing uphill, turn
the front wheels away from the
curb to help keep the vehicle from
rolling. If there is no curb or if it is
required by other conditions to
keep the vehicle from rolling, block
the wheels.• Under some conditions your park-
ing brake can freeze in the
engaged position. This is most like-
ly to happen when there is an
accumulation of snow or ice
around or near the rear brakes or if
the brakes are wet. If there is a risk
that the parking brake may freeze,
apply it only temporarily while you
put the shift lever in P and block
the rear wheels so the car cannot
roll. Then release the parking
brake.
• Do not hold the vehicle on the
upgrade with the accelerator
pedal. This can cause the trans-
mission to overheat. Always use
the brake pedal or parking brake.

➀CRUISE indicator
➁SET indicator
The cruise control system allows you
to program the vehicle to maintain a
constant speed without pressing the
accelerator pedal.
This system is designed to function
above approximately 40 km/h (25
mph) and below approximately 180
km/h (113 mph).
✽NOTICE
During normal cruise control opera-
tion, when the SET switch is activat-
ed or reactivated after applying the
brakes, the cruise control will ener-
gize after approximately 3 seconds.
This delay is normal.
CRUISE CONTROL SYSTEM (IF EQUIPPED)
WARNING
• If the cruise control is left on,
(CRUISE indicator light in the
instrument cluster illuminat-
ed) the cruise control can be
activated unintentionally.
Keep the cruise control sys-
tem off (CRUISE indicator
light OFF) when the cruise
control is not in use, to avoid
inadvertently setting a speed.
• Use the cruise control system
only when traveling on open
highways in good weather.
• Do not use the cruise control
when it may not be safe to
keep the vehicle at a constant
speed, for instance, driving in
heavy or varying traffic, or on
slippery (rainy, icy or snow-
covered) or winding roads or
over 6% up-hill or down-hill
roads.
• Pay particular attention to the
driving conditions whenever
using the cruise control sys-
tem.
(Continued)
(Continued)
• Be careful when driving
downhill using the cruise con-
trol system, which may
increase the vehicle speed.

To decrease the cruising speed:
Follow either of these procedures:
• Push the SET- switch and hold it.
Your vehicle will gradually slow
down. Release the switch at the
speed you want to maintain.
• Push the SET- switch and release
it immediately. The cruising speed
will decrease by 2.0 km/h (1.2
mph) or 1.0 mph (1.6 km/h) each
time the SET- switch is operated in
this manner.
• You can set the speed to 40 km/h
(25 mph).
To temporarily accelerate with the
cruise control on:
If you want to speed up temporarily
when the cruise control is on,
depress the accelerator pedal.
Increased speed will not interfere
with cruise control operation or
change the set speed.
To return to the set speed, take your
foot off the accelerator.
If you press the SET- switch at
increased speed, the cruising speed
will be set again.
Cruise control will be canceled
when:
• Depressing the brake pedal.
• Shifting the shift lever into N
(Neutral).
• Pulling the CANCEL switch located
on the steering wheel.
• Decreasing the vehicle speed
lower than the memory speed by
15 km/h (9 mph).
• Decreasing the vehicle speed to
less than approximately 32 km/h
(20 mph).
• Increasing the vehicle speed to
more than approximately 200 km/h
(125 mph).
