Regen B mode
The paddle shifter is used to adjust
the regenerative braking level from 0
to 3 when the vehicle is in ECO
mode.
Left side (-): Increases the regen-
erative braking level and decelera-
tion.
Right side (+): Decreases the
regenerative braking level and
deceleration.
Information
• The Regen B function starts from
level 0 when starting your vehicle
and the system works only in D
(Drive).
• The Regen B function is cancelled
when the vehicle is shifted to the P
(Park), R (Reverse), N(Neutral) and
Sport mode.
• The Regen B function is cancelled
whilst ABS (Anti-lock Braking
System) and ESC (Electronic
Stability Control) is operating.
• Deceleration differences occur even
in the same system level according
to driving speeds (You may recog-
nize significant deceleration differ-
ences during city driving but you
may not feel differences whilst high
speed driving.)
Information
The paddle shifter does not operate
when:
• Both paddle shifters are pulled at
the same time.
• The vehicle is decelerating by
depressing the brake pedal.

Do not continue depressing the
brake pedal if the "
"indica-
tor 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 acti-
vated whilst 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.
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.
Parking brake
(foot type, if equipped)
Applying the parking brake
Always set the parking brake before
leaving the vehicle.

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. (Continued)On roads where the road sur-
face is pitted or has different
surface height.
Tyre 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.An Anti-Lock Braking System
(ABS) or an Electronic Stability
Control (ESC) system will not
prevent accidents due to
improper or dangerous driving
manoeuvres. Even though vehi-
cle 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-cov-
ered roads.

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.
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. We recom-
mend that you contact an authorised
HYUNDAI dealer 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 vehicle off.
Restart the vehicle. If the ABS
warning light is off, then your ABS
system is normal.
Otherwise, you may have a prob-
lem with your ABS system. We
recommend that you contact an
authorised 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.
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, we recommend
that you contact your HYUNDAI
dealer as soon as possible.

To prevent damage to the trans-
mission:
Do not allow wheel(s) of one axle
to spin excessively whilst the
ESC, ABS, and parking brake
warning lights are displayed. The
repairs would not be covered by
the vehicle warranty. Reduce
engine power and do not spin
the wheel(s) excessively whilst
these lights are displayed.
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 opera-
tion.
Vehicle Stability Management
(VSM)
The Vehicle Stability Management
(VSM) 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 tyres can sud-
denly become uneven.
VSM operation
VSM ON condition
The VSM operates when:
The Electronic Stability Control
(ESC) is on.
Vehicle speed is approximately
above 15 km/h on curve roads.
Vehicle speed is approximately
above 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.
i
NOTICE
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 substi-
tute for safe driving practices.
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
rearwards 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.
Information
• HAC does not operate when the shift
lever is in P (Park) or N (Neutral).
• HAC activates even when the ESC
(Electronic Stability Control) is off.
However, it does not activate, when
ESC does not operate normally.
Emergency Stop Signal (ESS)
(if equipped)
The Emergency Stop Signal system
alerts the driver behind by blinking
the stop lights, whilst sharply and
severely braking.
The system is activated when:
The vehicle suddenly stops. (The
deceleration power exceeds 7 m/s
2,
and the driving speed exceeds 55
km/h.)
The ABS is activated.
The hazard warning flasher automat-
ically turns ON after blinking the stop
lights:
When the driving speed is under
40 km/h,
When the ABS is deactivated, and
When the sudden braking situation
is over.The hazard warning flasher turns
OFF:
When the vehicle drives at a low
speed for a certain period of time.
The driver can manually turn OFF
the hazard warning flasher by
pressing the button.Information
The Emergency Stop Signal (ESS) sys-
tem will not work if the hazard warn-
ing flashers are already on.

Always be ready to depress the
accelerator pedal when starting
off an incline. The HAC activates
only for approximately 2 sec-
onds.
