Parking brake & Brake fluid
warning light
This warning light illuminates:
• When you set the Engine Start/Stop
button to the ON position.
-The parking brake & brake fluid
warning light illuminates for about 3
seconds and will then turn off once
the parking brake is released.
• Whenever the parking brake is
applied.
• Whenever the brake fluid level in the
reservoir is low.
-If the warning light illuminates
with the parking brake released, it
indicates the brake fluid level in the
reservoir is low.
If the brake fluid level in the reservoir is
low:
1. Drive carefully to the nearest safe
location and stop your vehicle.
2. With the engine stopped, check the
brake fluid level immediately and add
fluid as required (For more details,
refer to “Brake Fluid” section in
chapter 9). After adding brake fluid,
check all brake components for fluid
leaks. If a brake fluid leak is found, or
if the warning light remains on, or if
the brakes do not operate properly, do
not drive the vehicle. Have the vehicle
inspected by an authorized retailer of
Genesis Branded products.
Dual-diagonal braking system
Your vehicle is equipped with dual-
diagonal braking system. This means you
still have braking on two wheels even if
one of the dual systems should fail.
With only one of the dual systems
working, more than normal pedal travel
and greater pedal pressure is required to
stop the vehicle.
Also, the vehicle will not stop in as short
a distance with only a portion of the
brake system working.
If the brakes fail while you are driving,
shift to a lower gear for additional engine
braking and stop the vehicle as soon as it
is safe to do so.
WARNING
Parking Brake & Brake Fluid warning
light
Driving the vehicle with a warning light
ON is dangerous. If the Parking Brake
& Brake Fluid warning light illuminates
with the parking brake released, it
indicates that the brake fluid level is
low.
If this occurs, have the vehicle
inspected by an authorized retailer of
Genesis Branded products.

Paddle Shifter (Manual Shift
Mode)
ORS061009
The paddle shifter allows the driver to
shift gears without taking one’s hands off
the steering wheel.
The paddle shifter operates as follow.

[Pull the [+] or [-] paddle shifter once
to shift up or down one gear and the
system changes from automatic shift
mode to manual shift mode.

[To change back to automatic shift
mode from manual shift mode, do one
of the following:
-Pull the [+] paddle shifter for more
than one second.
-Drive the vehicle under 4 mph (7
km/h)
-Gently depress the accelerator
pedal for more than 6 seconds.
-Rotate the shift dial to the D (Drive)
position.
Information
If the [+] and [-] paddle shifters are pulled
at the same time, gear shift may not occur.
Good Driving Practices

[Never shift the gear from P (Park) or
N (Neutral) to any other position with
the accelerator pedal depressed.

[Never shift the gear into P (Park) when
the vehicle is in motion.
Be sure the vehicle is completely
stopped before you attempt to shift
into R (Reverse) or D (Drive).

[Do not shift the gear to N (Neutral)
when driving. If the gear is shifted to
N (Neutral) while driving, the vehicle
loses the ability to provide engine
braking. Doing so may increase the
risk of an accident.
Also, shifting the gear back to
D (Drive) while the vehicle is
moving may severely damage the
transmission.

[When driving uphill or downhill,
always shift to D (Drive) for driving
forward or shift to R (Reverse) for
driving rearwards. After selecting
D (Drive) or R (Reverse), check the
gear position indicated on the cluster
before driving. If the vehicle moves in
the opposite direction of the selected
gear, the engine may turn off and a
serious accident might occur due to
degraded brake performance.

[Do not drive with your foot resting
on the brake pedal. Even light, but
consistent pedal pressure can result
in the brakes overheating, brake wear
and possibly even brake failure.

6-23
06
Power-Assist Brakes
Your vehicle has power-assisted brakes
that adjust automatically through normal
usage.
In the event of a vehicle power failure,
the power assist for the brakes will not
work. You can still stop your vehicle, but
it will require greater force and increased
pedal travel than normal. The stopping
distance, however, will be longer than
with power brakes.
Information

[When the brake pedal is depressed
under certain driving conditions
or weather conditions, you may
temporarily hear a noise. This is
normal and does not indicate a problem
with your brakes.

[While driving on a road with deicing
chemicals, brake noise or abnormal
tire wear may occur due to deicing
chemicals. In a safe traffic condition,
additionally apply the brakes to remove
deicing chemicals on the brake discs
and pads.
WARNING
Take the following precautions:

[Do not drive with your foot resting
on the brake pedal. This will create
abnormal high brake temperatures,
excessive brake lining and pad wear,
and increased stopping distances.

[When descending down a long or
steep hill, use the paddle shifter
and manually downshift to a
lower gear in order to control your
speed without using the brake
pedal excessively. Applying the
brakes continuously will cause
the brakes to overheat and could
result in a temporary loss of braking
performance.

[Wet brakes may impair the vehicle's
ability to safely slow down; the
vehicle may also pull to one side
when the brakes are applied.
Applying the brakes lightly will
indicate whether they have been
affected in this way. Always test your
brakes in this fashion after driving
through deep water. To dry the
brakes, lightly tap the brake pedal to
heat up the brakes while maintaining
a safe forward speed until brake
performance returns to normal.
Avoid driving at high speeds until the
brakes function correctly.
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.
NOTICE
To avoid costly brake repairs, do not
continue to drive with worn brake pads.
Information
Always replace brake pads as complete
front or rear axle sets.
BRAKING SYSTEM

6-32
Driving Your Vehicle
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 distance
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 conditions.
ABS cannot prevent a loss of stability.
Always steer moderately when braking
hard. Severe or sharp steering 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 system
may result in a longer stopping distance
than for vehicles equipped with a
conventional brake system.
The ABS (
) warning light will stay
on for several seconds after the Engine
Start/Stop button is in the ON position.
During that time, 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 possible.
WARNING
If the ABS () warning light is on and
stays on, you may have a problem with
the ABS. Your power brakes will work
normally. To reduce the risk of serious
injury or death, contact your authorized
retailer of Genesis Branded products as
soon as possible.
NOTICE
When you drive on a road having poor
traction, such as an icy road, and apply
your brakes continuously, ABS will be
active continuously and the ABS (
)
warning light may illuminate. Pull your
vehicle over to a safe place and turn the
vehicle off.
Restart the vehicle. If the ABS warning
light is off, then your ABS system is
normal.
Otherwise, you may have a problem
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.

Electronic Stability Control (ESC)
ORS061014
Electronic Stability Control 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 management 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.
WARNING
Never drive too fast for the road
conditions when cornering. ESC will not
prevent accidents.
Excessive speed in turns, abrupt
maneuvers, and hydroplaning on wet
surfaces can result in severe accidents.
ESC operation
ESC ON condition
When the Engine Start/Stop button is
in the ON position, ESC and the ESC
OFF indicator lights illuminate for
approximately three seconds. After both
lights go off, ESC is enabled.
When operating
When ESC is in operation, 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 ESC activates, the engine may
not respond to the accelerator as it
does under routine conditions.

[If Smart Cruise Control was in use
when ESC activates, Smart Cruise
Control automatically disengages.
Smart Cruise Control can be
reengaged when the road conditions
allow. See “Smart Cruise Control
(SCC)” section in chapter 7 (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.

6-36
Driving Your Vehicle
VSM operation
When operating
When you apply your brakes under
conditions which may activate ESC, you
may hear sounds from the brakes, or feel
a corresponding sensation in the brake
pedal. This is normal and it means your
VSM is active.
Information
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.
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 indicator light
will go out.
WARNING
If the ESC () indicator light or MDPS
() warning light stays illuminated
or blinks, your vehicle may have a
malfunction with the VSM system.
When the warning light illuminates,
have the vehicle checked by an
authorized retailer of Genesis Branded
products as soon as possible.
NOTICE
Driving with wheels and tires with
different sizes may cause the VSM
system 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.
