Driving your vehicle
When operating
When the ESC is in opera-
tion, the ESC indicator light
blinks:
• When you apply your brakes under
conditions which may lock the
wheels, you may hear sounds from
the brakes, or feel a corresponding
sensation in the brake pedal. This is
normal and it means your ESC is
active.
• When the ESC activates, the
engine may not respond to the
accelerator as it does under routine
conditions.
• If the Cruise Control was in use
when the ESC activates, the Cruise
Control automatically disengages.
The Cruise Control can be reen-
gaged when the road conditions
allow.See "Cruise Control System"
later in this chapter.(if equipped)
• When moving out of the mud or
driving on a slippery road, the
engine rpm (revolutions per minute)
may not increase even if you press
the accelerator pedal deeply. This is
to maintain the stability and traction
of the vehicle and does not indicate
a problem.
ESC OFF condition
To cancel ESC operation :
• State 1
Press the ESC OFF button briefly.
The ESC OFF indicator light and
message (vehicles equipped with a
supervision cluster) will illuminate. In
this state, the traction control func-
tion of ESC (engine management) is
disabled, but the brake control func-
tion of ESC (braking management)
still operates.• State 2
Press and hold the ESC OFF button
continuously for more than 3 sec-
onds. The ESC OFF indicator light
and message (vehicles equipped
with a supervision cluster) illumi-
nates and a warning chime sounds.
In this state, both the traction control
function of ESC (engine manage-
ment) and the brake control function
of ESC (braking management) are
disabled.
If the ignition switch is placed to the
LOCK/OFF position when ESC is off,
ESC remains off. Upon restarting the
engine, the ESC will automatically
turn on again.

Driving your vehicle
To prevent damage to the trans-
mission:
• Do not allow wheel(s) of one
axle to spin excessively while
the ESC, ABS, and parking brake
warning lights are displayed.
The repairs would not be cov-
ered by the vehicle warranty.
Reduce engine power and do
not spin the wheel(s) excessive-
ly while these lights are dis-
played.
• When operating the vehicle on a
dynamometer, make sure the
ESC is turned off (ESC OFF light
illuminated).
Information
Turning the ESC off does not affect
ABS or standard brake system opera-
tion.
Vehicle Stability Management
(VSM) (if equipped)
The Vehicle Stability Management
(VSM) is a function of the Electronic
Stability Control (ESC) system. It
helps ensure the vehicle stays stable
when accelerating or braking sud-
denly on wet, slippery and rough
roads where traction over the four
tires can suddenly become uneven.
VSM operation
VSM ON condition
The VSM operates when:
• The Electronic Stability Control
(ESC) is on.
• Vehicle speed is approximately
above 15 km/h (9 mph) on curve
roads.
• Vehicle speed is approximately
above 20 km/h (12 mph) when the
vehicle is braking on rough roads.
When operating
When you apply your brakes under
conditions which may activate the
ESC, you may hear sounds from the
brakes, or feel a corresponding sen-
sation in the brake pedal. This is nor-
mal and it means your VSM is active.
i
NOTICE
Take the following precautions
when using the Vehicle Stability
Management (VSM):
•ALWAYS check the speed and
the distance to the vehicle
ahead. The VSM is not a sub-
stitute for safe driving prac-
tices.
•Never drive too fast for the
road conditions. The VSM sys-
tem will not prevent acci-
dents. Excessive speed in bad
weather, slippery and uneven
roads can result in severe
accidents.
WARNING

5-52
Driving your vehicle
Hill-Start Assist Control (HAC)
(if equipped)
helps prevent has the tendency to
slide backwards on a steep slope,
before depressing the accelerator
after a stop. The HAC prevents the
vehicle from sliding backwards and
releases the brake after 2 seconds or
when the accelerator pedal is
depressed.
Information
• The HAC does not operate when the
shift lever is in P (Park) or N (Neutral).
• The HAC activates even when the
ESC (Electronic Stability Control) is
off. However, it does not activate,
when the ESC does not normally
operate.
Emergency Stop Signal (ESS)
(if equipped)
The Emergency Stop Signal system
alerts the driver behind by blinking
the stop lights, while sharply and
severely braking.
The system is activated when:
• The vehicle suddenly stops. (The
deceleration power exceeds 7 m/s
2,
and the driving speed exceeds 55
km/h (34 mph).)
• The ABS is activated.
The hazard warning flasher automat-
ically turns ON after blinking the stop
lights, when the driving speeds is
decelerated under 40 km/h (25 mph),
when the ABS is deactivated, and
when the sudden braking situation is
over.
i
The HAC is activated only for
about 2 seconds, so always
depress the accelerator pedal
to begin driving upwards after a
stop.
WARNING

The hazard warning flasher turns
OFF, when the driving speed exceeds
10 km/h (6 mph) after a complete
stop. The hazard warning flasher
turns OFF, when the vehicle drives at
a low speed for a certain period of
time. The driver can manually turn
OFF the hazard warning flasher by
pressing the button.
Information
The Emergency Stop Signal (ESS) sys-
tem will not work if the hazard warn-
ing flasher already blinks.
Good braking practices
Wet brakes can be dangerous! The
brakes may get wet if the vehicle is
driven through standing water or if it
is washed. Your vehicle 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
vehicle 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 we recommend that you
call an authorized HYUNDAI dealer
for assistance.
DO NOT drive with your foot resting
on the brake pedal. Even light, but
constant pedal pressure can result in
the brakes overheating, brake wear,
and possibly even brake failure.
If a tire goes flat while you are driv-
ing, apply the brakes gently and
keep the vehicle 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 location.
Keep your foot firmly on the brake
pedal when the vehicle is stopped to
prevent the vehicle from rolling for-
ward.
i
Whenever leaving the vehicle or
parking, always come to a com-
plete stop and continue to
depress the brake pedal. Move
the shift lever into the P (Park)
position, then apply the parking
brake, and place the Engine
Start/Stop button in the OFF
position.
Vehicles parked with the park-
ing brake not applied or not
fully engaged may roll inadver-
tently and may cause injury to
the driver and others. ALWAYS
apply the parking brake before
exiting the vehicle.
WARNING

tions.
The ISG system is always active,
when the engine is running.
Information
When the engine is automatically
started by the ISG system, some warn-
ing lights (i.e. ABS, ESC, ESC OFF,
EPS, and parking brake warning
light) may illuminate for a few sec-
onds due to the low battery voltage.
However, it does not indicate a mal-
function with the ISG system.

The battery sensor deactiva-
tion
The battery sensor is deactivated,
when the battery is disconnected
from the negative pole for mainte-
nance purpose.
In this case, the ISG system is limit-
edly operated due to the battery sen-
sor deactivation. Thus, the driver
needs to take the following proce-
dures to reactivate the battery sen-
sor after disconnecting the battery.
Prerequisites to reactivate the
battery sensor
Keep the engine in the OFF status
for 4 hours, and attempt to restart the
engine 3 to 4 times for the battery-
sensor reactivation.
Pay extreme caution not to connect
any accessories (i.e. navigation and
black box) to the vehicle with the
engine in the OFF status. If not, the
battery sensor may not be reactivat-
ed.
Information
The ISG system may not operate in
the following situations.
- There is a malfunction with the IGS
system.
- The battery is weak.
- The brake vacuum pressure is low.
In those cases, we recommend you to
have the ISG system checked by an
authorized HYUNDAI dealer. • Use only the genuine HYUNDAI
ISG battery for replacement. If
not, the ISG system may not nor-
mally operate.
• Do not recharge the ISG battery
with a general battery charger. If
not, it may damage or explode
the ISG battery.
• Do not remove the battery cap. If
not, the battery electrolyte,
which is harmful to the human
body, may leak out.
