Disc Brakes Wear Indicator
When your brake pads are worn and
new pads are required, you will hear
a high pitched warning sound from
your front or rear brakes. You may
hear this sound come and go or it
may occur whenever you depress
the brake pedal.
Note that some driving conditions or
climates may cause a brake squeal
when you first apply (or lightly apply)
the brakes. This is normal and does
not indicate a problem with your
brakes.
To avoid costly brake repairs, do
not continue to drive with worn
brake pads.
Information
Always replace brake pads as com-
plete front or rear axle sets.
Electronic Parking Brake
(EPB)
Applying the parking brake
To apply the EPB (Electronic
Parking Brake):
1. Depress the brake pedal.
2. Pull the EPB switch towards you.
Make sure the Parking Brake
Warning Light comes on.

NOTICE
OHI058032
To reduce the risk of SERIOUS
INJURY or DEATH, do not oper-
ate the EPB while the vehicle is
moving except in an emergency
situation. It could damage the
brake system and lead to an
accident.

Anti-lock Brake System (ABS)
ABS is an electronic braking system
that helps prevent a braking skid.
ABS allows the driver to steer and
brake at the same time.
Using ABS
To obtain the maximum benefit from
your ABS in an emergency situation,
do not attempt to modulate your
brake pressure and do not try to
pump your brakes. Depress your
brake pedal as hard as possible.
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 ABS is
active.
ABS does not reduce the time or dis-
tance it takes to stop the vehicle.
Always maintain a safe distance from
the vehicle in front of you.
ABS will not prevent a skid that
results from sudden changes in
direction, such as trying to take a
corner too fast or making a sudden
lane change. Always drive at a safe
speed for the road and weather con-
ditions.
ABS cannot prevent a loss of stabili-
ty. Always steer moderately when
braking hard. Severe or sharp steer-
ing wheel movement can still cause
your vehicle to veer into oncoming
traffic or off the road.
On loose or uneven road surfaces,
operation of the anti-lock brake sys-
tem may result in a longer stopping
distance than for vehicles equipped
with a conventional brake system. An Anti-Lock Braking System
or an Electronic Stability
Control system will not prevent
accidents due to improper or
dangerous driving maneuvers.
Even though vehicle control is
improved during emergency
braking, always maintain a safe
distance between you and
objects ahead of you. Vehicle
speeds should always be
reduced during extreme road
conditions. The braking dis-
tance for vehicles equipped
with ABS or ESC may be longer
than for those without these
systems in the following road
conditions.
Drive your vehicle at reduced
speeds during the following
conditions:
• Rough, gravel or snow-cov-
ered roads.
• On roads where the road sur-
face is pitted or has different
surface height.
• Tire chains are installed on
your vehicle.
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.
WARNING

5-32
Driving your vehicle
The ABS warning light ( ) will stay
on for several seconds after the igni-
tion switch is in the ON position.
During that time, the ABS will go
through self-diagnosis and the light
will go off if everything is normal. If
the light stays on, you may have a
problem with your ABS. Contact an
authorized retailer of Genesis
Branded products as soon as possi-
ble.When you drive on a road having
poor traction, such as an icy road,
and apply your brakes continu-
ously, the ABS will be active con-
tinuously and the ABS warning
light ( ) may illuminate. Pull
your vehicle over to a safe place
and turn the engine off.
Restart the engine. If the ABS
warning light is off, then your ABS
system is normal.
Otherwise, you may have a prob-
lem with your ABS system.
Contact an authorized retailer of
Genesis Branded products as
soon as possible.
Information
When you jump start your vehicle
because of a drained battery, 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.
Have the battery recharged before
driving the vehicle.
i
NOTICE
If the ABS warning light ( ) is
on and stays on, you may have
a problem with the ABS. Your
power brakes will work normal-
ly. To reduce the risk of serious
injury or death, contact your
authorized retailer of Genesis
Branded products as soon as
possible.

Electronic Stability Control
(ESC)
The Electronic Stability Control sys-
tem helps to stabilize the vehicle dur-
ing cornering maneuvers. ESC
checks where you are steering and
where the vehicle is actually going.
ESC applies braking pressure to any
one of the vehicle's brakes and inter-
venes in the engine management
system to assist the driver with keep-
ing the vehicle on the intended path.
It is not a substitute for safe driving
practices. Always adjust your speed
and driving to the road conditions.
ESC operation
ESC ON condition
When the ignition switch is in the ON
position, the ESC and the ESC OFF
indicator lights illuminate for approxi-
mately three seconds. After both
lights go off, the ESC is enabled.
When operating
When the ESC is in oper-
ation, 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 rou-
tine conditions.
• If the Smart Cruise Control was in
use when the ESC activates, the
Smart Cruise Control automatically
disengages. The Smart Cruise
Control can be reengaged when
the road conditions allow. See
"Smart Cruise Control System"
later in this chapter.
• 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 sta-
bility and traction of the vehicle and
does not indicate a problem.
OHI058037
Never drive too fast for the road
conditions when cornering. The
ESC system will not prevent
accidents.
Excessive speed in turns, abrupt
maneuvers, and hydroplaning
on wet surfaces can result in
severe accidents.

Vehicle Stability Management
(VSM)
The Vehicle Stability Management is
a function of the Electronic Stability
Control system. It helps the vehicle
stay stable when accelerating or
braking suddenly 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 is
on.
• Vehicle speed is approximately
above 9 mph (15 km/h) on curve
roads.
• Vehicle speed is approximately
above 12 mph (20 km/h) 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.
The VSM does not operate when:
• Driving on a banked road such
as gradient or incline.
• Driving in reverse.
• The ESC OFF indicator light is
on.
• The MDPS (Motor-Driven Power
Steering) warning light ( ) is
on or blinks.
NOTICE
Take the following precautions
when using the Vehicle Stability
Management :
• 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

5-37
05
Driving with wheel and tire sizes dif-
ferent than original-equipment may
cause the ESC system to malfunc-
tion. Before replacing tires, make
sure all four tires and wheels are the
same as the original size. Never
drive the vehicle with different sized
tires and wheels installed.
Hill-Start Assist Control (HAC)
The Hill-Start Assist Control helps
prevent the vehicle from rolling back-
wards when starting a vehicle from a
stop on a hill. The system operates
the brakes automatically for approxi-
mately 2 seconds and releases the
brake after 2 seconds or when the
accelerator pedal is depressed.
• The HAC does not operate when
the gear is shifted to P (Park) or
N (Neutral).
• The HAC activates even though
the ESC (Electronic Stability
Control) is off but does not acti-
vate when the ESC has malfunc-
tioned.
NOTICE
If the ESC indicator light ( ) or
MDPS warning light ( ) stays
on or blinks, your vehicle may
have a malfunction with the
VSM system.When the warning
light illuminates, have your vehi-
cle checked by an authorized
retailer of Genesis Branded
products as soon as possible.
WARNING
Always be ready to depress the
accelerator pedal when starting
off on a incline. The HAC acti-
vates only for approximately 2
seconds.

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 products 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 call an authorized retailer
of Genesis Branded products 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. Whenever leaving the vehicle or
parking, always come to a com-
plete stop and continue to
depress the brake pedal. Shift
the gear to P (Park), apply the
parking brake, and press the
Engine Start/Stop button to the
OFF.
Vehicles with the parking brake
not fully engaged are at risk for
moving inadvertently and caus-
ing injury to yourself or others.
WARNING

Prerequisite for activation
The FCA system will activate when
'Active Assist' or 'Warning Only' under
Forward Safety is selected in the AVN
system screen, and when the follow-
ing prerequisites are satisfied.
• ESC (Electronic Stability Control)
is on.
• Vehicle speed is over 5 mph (8
km/h). (The FCA is only activated
within a certain speed range.)
• The system detects a pedestrian,
cyclist or a vehicle in front, which
may collide with your vehicle.
However, FCA may not be activat-
ed or may only sound a warning
alarm depending on the driving or
vehicle conditions.
FCA may not operate properly
according to the frontal situation or
the direction of a pedestrian or
cyclist.
FCA Warning Message and
Brake Control
FCA produces warning messages,
warning alarms, and emergency
braking based on the level of risk of
a frontal collision, such as when a
vehicle ahead suddenly brakes, or
the system detects that a collision
with a pedestrian or cyclist is immi-
nent.

do not attempt to set or can-
cel the FCA while driving the
vehicle. Always completely
stop the vehicle at a safe
place before setting or cancel-
ing the system.
• FCA automatically activates
upon placing the Engine
Start/Stop button to the ON or
START position. The driver
can deactivate FCA by cancel-
ing the system setting in the
AVN system screen.
• FCA automatically deacti-
vates upon canceling ESC.
When ESC is canceled, FCA
cannot be activated in the
AVN system screen. In this sit-
uation, the FCA warning light
will illuminate which is nor-
mal.
