Vehicle Stability Management (VSM)
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. Information
The VSM does not operate when:
 Driving on a banked road such as a gradient or incline.
 Driving in reverse.
 The ESC OFF indicator light is on.
 The EPS (Electric power steering) warning light ( ) is on or blinks.
i
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 substi-
tute for safe driving practices.
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 severeaccidents.
WARNING

Driving your vehicle
VSM OFF condition
To cancel VSM operation, press the
ESC OFF button. ESC OFF indicator
light ( ) will illuminate.
To turn on VSM, press the ESC OFF
button again. The ESC OFF indicatorlight will go out. Driving with wheels and tires with
different sizes may cause the VSM
system to malfunction. Before
replacing tires, make sure all fourtires and wheels are the same
size. Never drive the vehicle with
different sized tires and wheelsinstalled.
Hill-Start Assist Control (HAC)
The Hill-Start Assist Control (HAC)
helps prevent the vehicle from rolling
backwards when starting a vehicle
from a stop on a hill. The system
operates the brakes automatically for
approximately 2 seconds and releas-
es the brake after 2 seconds or when
the accelerator pedal is depressed.Information
 The HAC does not operate when the gear 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 operate nor-
mally.
i
NOTICE
If the ESC indicator light ( ) or
EPS warning light ( ) stays
on or blinks, your vehicle may
have a malfunction with the
VSM system. When the warning
light illuminates, have the vehi-
cle checked by an authorized
HYUNDAI dealer as soon as
possible.
WARNING
Always be ready to depress the
accelerator pedal when starting
off an incline.The HAC activates
only for approximately 2 sec-onds.

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. If the braking action does
not return to normal, stop as soon as
it is safe to do so and call an author-
ized HYUNDAI dealer for assistance.
DO NOT drive with your foot resting
on the brake pedal. Even light, butconstant 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.
Whenever leaving the vehicle or
parking, always come to a com-
plete stop and continue to
depress the brake pedal. Shift
to the P (Park) position, then
apply the parking brake, and
place the POWER button in theOFF 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.

Prerequisite for activation
FCA gets ready to be activated,
when 'Active Assist' or 'Warning
Only' under Forward Safety is select-
ed in the cluster LCD display, and
when the following prerequisites aresatisfied.
- ESC (Electronic Stability Control)is on.
- Vehicle speed is over 8 km/h (5 mph). (FCA is only activated within
a certain speed range.)
- The system detects a pedestrian, cyclist (if equipped) or a vehicle in
front, which may collide with your
vehicle. However, FCA may not be
activated or may only sound a
warning alarm depending on the
driving or vehicle conditions.
The FCA may not operate properly according to the frontal situation,
the direction of pedestrian orcyclist (if equipped) and speed.
FCA warning message and
brake control
FCA produces warning messages,
warning alarms, and emergency
braking based on the level of risk ofa frontal collision, such as when a
vehicle ahead suddenly brakes, orthe system detects that a collision
with a pedestrian or cyclist (ifequipped) is imminent.To avoid driver distractions, do not attempt to set or can-cel FCA while driving the vehi-
cle. Always completely stop
the vehicle at a safe place
before setting or cancelingthe system.
FCA automatically activates
when the POWER button is in
the ON position. The driver
can deactivate FCA by cancel-ing the system setting on the
LCD display.
FCA automatically deactivates upon canceling the ESC
(Electronic Stability Control).When the ESC is canceled,
FCA cannot be activated on
the LCD display. In this situa-
tion, the FCA warning light will
illuminate which is normal.

Driving your vehicle
Collision Warning (First warning)
This warning message appears on
the LCD display with a warning
chime. Additionally, some vehicle
system intervention occurs to help
decelerate the vehicle. If FCA detects a vehicle in front,
the system operates when your
vehicle speed is between 8 km/h (5mph) and 180 km/h (110 mph).
Maximum vehicle speed maydecrease depending on the condi-
tion of the vehicle ahead and sur-
roundings.
If FCA detects a pedestrian or cyclist in front, the system operates
when your vehicle speed is
between 8 km/h (5 mph) and 70
km/h (45 mph). Maximum vehicle
speed may decrease depending
on the condition of the pedestrian
or cyclist ahead and surroundings.
If you select 'Warning Only' for the system setting, FCA system acti-
vates and produces only warning
alarms in accordance with the col-
lision risk levels. You should control
the brake directly because FCA
system will not control the brake.
Emergency braking
(Second warning)
This warning message appears on
the LCD display with a warning
chime. Additionally, some vehicle
system intervention occurs to help
decelerate the vehicle.
