The Electronic Stability Control
(ESC) system helps to stabilize the
vehicle during 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 intervenes in the engine man-
agement system to assist the driver
with keeping 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 Engine Start/Stop button
is in the ON position, the ESC and
the ESC OFF indicator lights illumi-
nate for approximately three sec-
onds. After both lights go off, the
ESC is enabled.
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 rou-
tine conditions.
If the Cruise Control was in use when the ESC activates, the
Cruise Control automatically disen-
gages. The Cruise Control can be
reengaged when the road condi-
tions 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 sta-
bility and traction of the vehicle and
does not indicate a problem.
Never drive too fast for the road
conditions or too quickly 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.

ESC OFF condition
To cancel ESC operation :
State 1
Press the ESC OFF button briefly.
The ESC OFF indicator light and
message "Traction Control disabled"
will illuminate. In this state, the trac-
tion control function of ESC (engine
management) is disabled, but the
brake control function of ESC (brak-
ing management) still operates.
Press and hold the ESC OFF button
continuously for more than 3 sec-
onds. The ESC OFF indicator light
and message "Traction and Stability
Control disabled" illuminates and a

both the traction control function of
ESC (engine management) and the
brake control function of ESC (brak-
ing management) are disabled.
If the Engine Start/Stop button is
pressed to the OFF position when
ESC is off, ESC remains off. Upon
restarting the engine, the ESC will
automatically turn on again.
Indicator lights
When the Engine Start/Stop button
is pressed to the ON position, the
ESC indicator light illuminates, then
goes off if the ESC system is operat-
ing normally.
The ESC indicator light blinks when-
ever the ESC is operating.
If ESC indicator light stays on, your
vehicle may have a malfunction with
the ESC system. When this warning
light illuminates have your vehicle
checked by an authorized retailer of
Genesis Branded products as soon
as possible.
The ESC OFF indicator light comes
on when the ESC is turned off.

5Driving with wheels and tires with
different sizes may cause the ESC
system to malfunction. Before
replacing tires, make sure all four
tires and wheels are the same
size. Never drive the vehicle with
different sized wheels and tires
installed.
ESC OFF usage
When Driving
The ESC OFF mode should only be
used briefly to help free the vehicle if
stuck in snow or mud by temporarily
stopping operation of the ESC to
maintain wheel torque.
To turn ESC off while driving, press
the ESC OFF button while driving on
a flat road surface.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 operation.

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 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 rearward.
ESC OFF indicator light is on.
EPS (Electric Power Steering) warning light ( ) is on or
blinks.
Driving with wheels and tires with dif-
ferent sizes may cause the ESC sys-
tem to malfunction. Before replacing
tires, make sure all four tires and
wheels are the same size. Never
drive the vehicle with different sized
tires and wheels installed.
NOTICE
If ESC indicator light ( ) or
EPS warning light ( ) stays on
or blinks, your vehicle may have
a malfunction with the VSM sys-
tem. When the warning light illu-
minates, have your vehicle
checked by an authorized retail-
er of Genesis Branded products
as soon as possible.
WARNING
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.

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.
The HAC does not operate whenthe vehicle 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.
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 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.
NOTICE
Whenever leaving the vehicle or
parking, always come to a com-
plete stop and continue to
depress the brake pedal. Shift
the vehicle to neutral (for manu-
al transmission vehicle) or P
(Park, for automatic transmis-
sion vehicle), apply the parking
brake, and press the Engine
Start/Stop button to 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
Always be ready to depress the
accelerator pedal when starting
off on a incline. The HAC activates
only for approximately 2 seconds.

Tires refer to "Winter Driving" in
this chapter.
Keep sufficient distance between your vehicle and the vehicle in front
of you.
When approaching a stop sign or stop light, release the accelerator
pedal to provide engine braking
during deceleration.
Avoid speeding, rapid acceleration, sudden brake applications, and
sharp turns to prevent skids.
Driving in sand or mud
Maintain slow and constant speed.
Keep sufficient distance betweenyour vehicle and the vehicle in front
of you.
Reduce vehicle speed and always check the road condition.
Avoid speeding, rapid acceleration, sudden brake applications, and
sharp turns to prevent getting
stuck.
When the vehicle is stuck in snow,
sand or mud, avoid running the
engine continuously at high rpm,
doing so may damage the tires,
transmission, differential or AWD
system.

Tire size mismatch. Check all tire
sizes.
If your vehicle is equipped with differ-
ent tires (size, type, etc.) on the front
and rear, the message will appear. To
use the AWD system, equip the vehi-
cle with the same tires on the front
and rear.
Towing
AWD vehicles must be towed with all
wheels off the ground, either on a
flatbed tow truck or using doilies.
For more details, refer to "Towing"
in chapter 6.
Vehicle inspection
If the vehicle needs to be operatedon a vehicle lift do not attempt to
stop any of the four wheels for turn-
ing. This could damage the sys-
tem.
Never engage the parking brake while running the engine on a car
lift. This may damage the AWD
system.
Dynamometer testing
An AWD vehicle must be tested on a
special four wheel chassis dynamome-
ter.

Driving your vehicle
An AWD vehicle should not be tested
on a 2WD roll tester. If a 2WD roll
tester must be used, perform the fol-
lowing procedure:
1. Check the tire pressures recom- mended for your vehicle.
2. Place the rear wheels on the roll tester for a speedometer test as
shown in the illustration.
3. Release the parking brake.
4. Place the front wheels on the tem- porary free roller as shown in the
illustration. Limited Slip Differential refers to a
feature equipped with a mechanism
that controls the differential functions
of the wheels in the rear differential.
The Limited Slip Differential helps
improve handling performance when
circling at high speed.
Keep away from the front of the
vehicle while the vehicle is in
gear on the dynamometer. The
vehicle can jump forward and
cause serious injury or death.
