Driving on hills
B6003204
When coasting uphill or downhill, the
front sensors may not detect the vehicle
ahead or suddenly detect the vehicle
ahead at the end of the incline or at the
point where the incline changes. The
regenerative braking intensity is adjusted
automatically changing your vehicle
speed. Brake as needed to reduce your
driving speed.
Changing lanes
B6003205
• When a vehicle moves into your lane from an adjacent lane, it cannot be
detected by the sensors until it is in the
sensor's detection range.
• The smart regeneration system may not immediately detect the vehicle when
your vehicle changes lanes abruptly.
Braking System
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. So
increase the regeneration braking level
with the left paddle shifter to decrease
the speed.
• When descending down a long or steep hill, use the paddle shifter to increase
the regeneration braking level in order
to decrease 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 decelerate. Because
wet brakes increase braking distance
and cause noise troubles, select 0 step
of the regenerative braking system and
depress the brake pedal around 10
times, with keeping the safe distance
from other vehicles, lightly in order to
dry the braking system. Such
procedure may decrease the driving
distance by restraining the
regenerative braking system, which is
not a system malfunction. Inspect the
braking system after car wash or
driving over wet road conditions.

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.

Information Always replace brake pads as complete front
or rear axle sets.
WARNING Frequent braking may deform
components and worn the disc brake
causing vibration when braking. Observe
the speed limit to prevent brake damage
from excessive braking.
Brake wear, noise, vibration from
excessive braking or deformation of the
brakes caused by repeatedly braking in
high speed, racing on tracks, etc. can be
excluded from warranty coverage.

Anti-Lock Brake System (ABS)
WARNING Anti-Lock Braking System (ABS) or
Electronic Stability Control (ESC) 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
distance 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-covered roads.
• On roads where the road surface is pitted or has different surface height.
• Tire chains are installed on your vehicle.
The safety features of ABS or ESC
equipped vehicle should not be tested by
high speed driving or cornering. This
could endanger the safety of yourself or
others.
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 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 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 HYUNDAI dealer 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
HYUNDAI dealer 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)
B6004101
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
electric vehicle control 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 Start/Stop button is in the ON
position, ESC and the ESC OFF indicator
lights illuminate for about 3 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 vehicle may not respond to the accelerator as it
does under routine conditions.

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 ESC, to maintain wheel
torque.
To turn ESC off while driving, press the
ESC OFF button while driving on a flat
road surface.

Information • Turning ESC off does not affect ABS or standard brake system operation.
• Select 0 step of the regenerative braking system and depress the brake pedal around
10 times to efficiently apply brake disc
cleaning.
Brake disc cleaning may decrease the
driving distance by restraining the regenerative braking system. After brake
disc cleaning, the regenerative braking
system may be restored.
If the regenerative braking system is not
restored after the brake disc cleaning, have
the vehicle inspected by an authorized
HYUNDAI dealer.
Vehicle Stability Management
(VSM)
Vehicle Stability Management is a
function of the Electronic Stability
Control (ESC) 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.
WARNING Take the following precautions when
using Vehicle Stability Management:
• ALWAYS check the speed and the distance to the vehicle ahead. VSM is
not a substitute for safe driving
practices.
• Never drive too fast for the road conditions. VSM will not prevent
accidents. Excessive speed in bad
weather, on slippery and uneven roads
can result in severe accidents.
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.

Hill-Start Assist Control (HAC)
Hill-Start Assist Control helps prevent the
vehicle from rolling backwards when
starting a vehicle from a stop on a hill. The
system operates the brakes automatically
for about 2 seconds (maximum of 5
seconds when the accelerator pedal is
slightly depressed during HAC operation)
and releases the brake after 2 seconds or
when the accelerator pedal is depressed.
WARNING Always be ready to depress the
accelerator pedal when starting off an
incline. Hill-Start Assist Control activates
only for about 2 seconds (maximum of 5
seconds when the accelerator pedal is
slightly depressed during HAC operation).
Information • Hill-Start Assist Control does not operate when the gear is shifted to P (Park) or N
(Neutral).
• Hill-Start Assist Control activates even when the ESC (Electronic Stability
Control) is off. However, it does not
activate, when ESC does not operate
normally.
Brake Assistant System (BAS)
The Brake Assistant System provides
additional pressure when the brake pedal
is momentarily and strongly depressed in
a situation sudden braking is required
while driving.
The Brake Assistant System reduces the
time for ABS(Anti-Lock Brake System)
control to enter and consequently
reduces the braking distance, by
providing additional pressure up to the
point of ABS intervention.
Hyundai_CE_en_US.book Page 34
Page 323 of 582

6-35
BAS operation
• When the vehicle speed is more than 18 mph (30 km/h) and the ABS control is
not entered.
• When the brake pedal is depressed strongly over a certain level.
• When the friction of the road surface is above a certain level.
BAS operation off
• The vehicle speed is below 6 mph (10 km/h).
• The brake pedal is depressed over a certain conditions.
• The friction of the road surface is below a certain level.
WARNING The system may not operate depending
on driver's driving habit, the degree to
which the brake pedal is depressed and
the road surface condition.
Good Braking Practices
WARNING Whenever leaving the vehicle or parking,
always come to a complete stop and
continue to depress the brake pedal. Shift
the gear to the P (Park) position, then
apply the parking brake, and press the
Start/Stop button to the OFF position.
Vehicles parked with the parking brake
not applied or not fully engaged may roll
inadvertently and may cause injury to the
driver and others. ALWAYS apply the
parking brake before exiting the vehicle.
Be aware of wet brakes. 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 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 driving,
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 forward.

“Tire Replacement” section in Chapter
9.
• Turn on your headlights to make it easier for others to see you. Using your
headlights when using your windshield
wipers is required in some jurisdictions.
• Driving too fast through large puddles may affect your brakes. If you must go
through puddles, try to drive through
them slowly.
• If you believe your brakes are wet, apply them several times while the
vehicle is moving slowly.
Hydroplaning
If the road is wet enough and you are
going fast enough, your vehicle may have
little or no contact with the road surface
and actually ride on the water. The best
advice is SLOW DOWN when the road is
wet.
The risk of hydroplaning increases as the
depth of tire tread decreases, For more
information, refer to the “Tire
Replacement” section in chapter 9.
Driving in Flooded Areas
Avoid driving through flooded areas
unless you are sure the water is not
deeper than the bottom of the wheel hub.
If you are not sure, turn around and find a
different route. Drive through any water
slowly. Allow adequate stopping distance
because the brake performance can be
reduced.
After driving through water, dry the
brakes by gently applying them several
times while the vehicle is moving slowly.
Highway Driving
Tires
Adjust the tire inflation pressure, as
specified. Under-inflation may overheat
or damage the tires.
Do not install worn-out or damaged tires,
which may reduce traction or fail.
Information Never over-inflate your tires above the
maximum inflation pressure, as specified on
your tires.
Coolant and high voltage battery
Driving at higher speeds on the highway
consumes more electric energy and is
less efficient than driving at a slower,
more moderate speed. Maintain a
moderate speed in order to conserve
electric energy when driving on the
highway.
Be sure to check both the coolant level
and the electric energy level before
driving.
