Vehicle recognition
OTM058128
Some vehicles in your lane cannot be
recognized by the sensor:
- Narrow vehicles such as motorcycles or
bicycles
- Vehicles offset to one side
- Slow-moving vehicles or sudden-
decelerating vehicles
- Stopped vehicles (When the vehicle
ahead drives away, the system may not
detect a stopped vehicle.)
- Vehicles with small rear profile such as
trailers with no loads
A vehicle ahead cannot be recognized
correctly by the sensor if any of following
occurs:
- When the vehicle is pointing upwards
due to overloading in the luggage
compartment.
- While the steering wheel is operating.
- When driving to one side of the lane.
- When driving on narrow lanes or on
curves.
- Apply the brake or accelerator pedal if
necessary.
WARNING
When using the Smart Recuperation
System take the following precautions:

[If an emergency stop is necessary,
you must apply the brakes.

[Keep a safe distance according to
road conditions and vehicle speed. If
the vehicle to vehicle distance is too
close during a high-speed driving, a
serious collision may result.

[Always maintain sufficient braking
distance and decelerate your vehicle
by applying the brakes if necessary.

[The Smart Recuperation System
cannot recognize a stopped vehicle,
pedestrians or an oncoming vehicle.
Always look ahead cautiously to
prevent unexpected and sudden
situations from occurring.

[Vehicles moving in front of you with
a frequent lane changes may cause
a delay in the system's reaction or
may cause the system to react to a
vehicle actually in an adjacent lane.
Always drive cautiously to prevent
unexpected and sudden situations
from occurring.

[The Smart Recuperation System
may not recognize complex driving
situations so always pay attention to
driving conditions and control your
vehicle speed.
NOTICE
The Smart Recuperation System may
not operate temporarily due to:

[Electrical interference

[Modifying the suspension

[Differences of tire abrasion or tire
pressure

[Installing different type of tires

Power-Assist Brakes
Your vehicle has power-assisted brakes
that adjust automatically through normal
usage.
If the vehicle is not running or is turned
off while driving, the power assist for
the brakes will not work. You can still
stop your vehicle by applying greater
force to the brake pedal than typical.
The stopping distance, however, will be
longer than with power brakes.
When the vehicle is not running, the
reserve brake power is partially depleted
each time the brake pedal is applied.
Do not pump the brake pedal when the
power assist has been interrupted.
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 shift lever
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.
NOTICE

[Do not continue depressing
the brake pedal if the ""
indicator is OFF. The battery may be
discharged.

[Noise and vibration generated
during braking is normal.

[Under normal operation, electric
brake pump noise and motor
vibration may occur temporarily in
below cases.
-When the pedal is depressed
suddenly.
-When the pedal is repeatedly
depressed in short intervals.
-When the ABS function is activated
while braking.

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.
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.
Electronic Parking Brake (EPB)
Applying the parking brake
ONE1061015
To apply EPB (Electronic Parking Brake):
1. Depress and hold the brake pedal.
2. Pull up the EPB switch.
Make sure the Parking Brake warning
light comes on.
EPB (Electronic Parking Brake) may be
automatically applied when:

[Requested by other systems

[The driver turns the vehicle off while
Auto Hold is operating.

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.
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 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)
ONE1061020
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 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 vehicle may
not respond to the accelerator as it
does under routine conditions.

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

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.
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 EPS (Electric power steering)
warning light (
) is on or blinks.

06

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 EPS
() 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 HYUNDAI dealer 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.
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 approximately
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 approximately 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.

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.

Information
The ESC system must be turned OFF
before rocking the vehicle.
NOTICE
If you are still stuck after rocking the
vehicle a few times, have the vehicle
pulled out by a tow vehicle to avoid
motor overheating, possible damage
to the reduction gear, and tire damage.
See “Towing” section in chapter 8.
Smooth Cornering
Avoid braking or gear changing in
corners, especially when roads are wet.
Ideally, corners should always be taken
under gentle acceleration.
Driving at Night
Night driving presents more hazards than
driving in the daylight. Here are some
important tips to remember:

[Slow down and keep more distance
between you and other vehicles, as it
may be more difficult to see at night,
especially in areas where there may
not be any street lights.

[Adjust your mirrors to reduce the glare
from other drivers’ headlamps.

[Keep your headlamps clean and
properly aimed. Dirty or improperly
aimed headlamps will make it much
more difficult to see at night.

[Avoid staring directly at the
headlamps of oncoming vehicles. You
could be temporarily blinded, and it
will take several seconds for your eyes
to readjust to the darkness.
Driving in the Rain
Rain and wet roads can make driving
dangerous. Here are a few things to
consider when driving in the rain or on
slick pavement:

[Slow down and allow extra following
distance. A heavy rainfall makes
it harder to see and increases the
distance needed to stop your vehicle.

[Turn OFF your Cruise Control. (if
equipped)

[Replace your windshield wiper blades
when they show signs of streaking or
missing areas on the windshield.

[Be sure your tires have enough tread.
If your tires do not have enough tread,
making a quick stop on wet pavement
can cause a skid and possibly lead to
an accident. See “Tire Tread” section
in chapter 9.

[Turn on your headlamps to make it
easier for others to see you.

[Driving too fast through large puddles
can affect your brakes. If you must go
through puddles, try to drive through
them slowly.

[If you believe your brakes may be wet,
apply them lightly while driving until
normal braking operation returns.

06
6-55
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, refer
to “Tire Tread” section in chapter 9.
Driving in Flooded Areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel hub.
Drive through any water slowly. Allow
adequate stopping distance because
brake performance may 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, as specified.
Under-inflation may overheat or damage
the tires.
Do not install worn-out or damaged tires,
which may reduce traction or fail the
braking operation.
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.
