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

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.

6-37
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).

ESC OFF condition
To cancel ESC operation:

[State 1
Press the ESC OFF button briefly.
The ESC OFF indicator light and/or
message 'Traction Control disabled'
will illuminate. In this state, the traction
control function of ESC (electric vehicle
control management) is disabled, but the
brake control function of ESC (braking
management) still operates.

[State 2
Press and hold the ESC OFF button
continuously for more than 3 seconds.
The ESC OFF indicator light and/or
message 'Traction & Stability Control
disabled' illuminates and a warning
chime sounds. In this state, both the
traction control function of ESC (electric
vehicle control management) and the
brake control function of ESC (braking
management) are disabled.
If the Start/Stop button is pressed to
the OFF position when ESC is off, ESC
remains off. Upon restarting the vehicle,
ESC will automatically turn on again.
When ESC (electric vehicle control) is
deactivated, the vehicle will loose the
traction and stability if the vehicle is
driven by abrupt steering wheel control.
It is possible that the tire may make a
collision with the connected parts of the
tire. We recommend to do not turn off
ESC while driving the vehicle for your
safety.

NOTICE
Driving 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 ESC, to maintain wheel
torque.
To turn ESC off while driving, press the
ESC OFF button while driving on a flat
road surface.
NOTICE
To prevent damage to the reduction
gear:

[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 covered by the vehicle warranty.
Reduce motor power and do not spin
the wheel(s) excessively while these
lights are displayed.

[When operating the vehicle
on a dynamometer, make sure
ESC is turned off (ESC OFF light
illuminated).
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.

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.

6-43
When All Wheel Drive(AWD) is
activated, driving forces are distributed
appropriately to front and rear wheels.
It could improve driving performance by
maximizing the driving force of vehicles
on severe road conditions such as steep
hills, unpaved, slippery, etc.
Advantage of electronic AWD
1. Improvement of straight stability
2. Improvement of driving performance
on curve
3. Secure stability on severe condition
such as wet and sandy roads.
4. Improvement of energy efficiency
from driving mode automatic control.
Information
AWD vehicles could change the
engagement status of the motor according
to the situation required. Auto changing
the driving mode(2WD/AWD)helps
improve energy efficiency and driving
stability.
WARNING
To reduce the risk of SERIOUS INJURY
or DEATH:

[Avoid high speeds when cornering or
turning.

[Do not make quick steering wheel
movements, such as sharp lane
changes or fast, sharp turns.

[The risk of a rollover is greatly
increased if you lose control of your
vehicle at highway speeds.

[Loss of control often occurs if two or
more wheels drop off the roadway
and the driver over steers to reenter
the roadway.

[In the event your vehicle leaves
the roadway, do not steer sharply.
Instead, slow down before pulling
back into the travel lanes.
NOTICE

[Do not drive in water if the level
is higher than the bottom of the
vehicle.

[Check your brake condition once
you are out of mud or water. Depress
the brake pedal several times as you
move slowly until you feel normal
braking return.

[Shorten your scheduled
maintenance interval if you drive in
off-road conditions such as sand,
mud or water (see "Maintenance
Under Severe Usage Conditions"
section in chapter 9).

[Always wash your vehicle thoroughly
after off road use, especially the
bottom of the vehicle.

[Be sure to equip the vehicle with four
tires of the same size and type.

[Make sure that a full time AWD
vehicle is towed by a flat bed tow
truck.

For safe AWD operation
Before driving

[Make sure all passengers are wearing
seat belts.

[Sit upright and closer to the steering
wheel than usual. Adjust the steering
wheel to a position comfortable for
you to drive.
Driving on snow-covered or icy roads

[Start off slowly by applying the
accelerator pedal gently.

[Use snow tires or tire chains.

[Keep sufficient distance between your
vehicle and the vehicle in front of you.

[Using regenerative braking helps the
steering on the downhill. However, it
may be difficult to adjust the vehicle
while coasting using regenerative
braking, so avoid using the third level
of regenerative braking as much as
possible.

[Avoid speeding, rapid acceleration,
sudden brake applications, and sharp
turns to prevent skids.

[It is difficult to start again if the
vehicle stops on an uphill road. Keep
your distance from other vehicles and
drive slowly.
Information
When using Snow Tires, mount them on
all four wheels.
When using tire chains, install them on the
rear tires.
However, driving speed must be below 30
km/h and minimize the driving distance.
High-speed or long-term driving with
tire chains installed may malfunction or
damage the AWD system.
For more details on Snow Tires and Tire
Chains, refer to "Winter Driving" section
later in this chapter.
Driving in sand or mud

[Maintain slow and constant speed.

[Use tire chains driving in mud if
necessary.

[Keep sufficient distance between your
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.
NOTICE
When the vehicle is stuck in snow, sand
or mud, place a nonslip material under
the drive wheels to provide traction
OR slowly spin the wheels in forward
and reverse directions which causes
a rocking motion that may free the
vehicle.
Driving up or down hills

[Driving uphill
- Before starting off, check if it is
possible to drive uphill.
- Drive as straight as possible.

[Driving downhill
- Do not change gear while driving
downhill. Select gear before driving
downhill.
- Drive straight as possible.
WARNING
Exercise extreme caution driving up or
down steep hills. The vehicle may flip
over depending on the grade, terrain,
water and mud conditions.

06
6-45
WARNING
Do not drive across the contour of steep
hills. A slight change in the wheel angle
can destabilize the vehicle, or a stable
vehicle may lose stability if the vehicle
stops its forward motion. Your vehicle
may roll over and lead to a serious injury
or death.
Additional driving conditions

[Become familiar with the off-road
conditions before driving.

[Always pay attention when driving off-
road and avoid dangerous areas.

[Drive slowly when driving in heavy
wind.

[Reduce vehicle speed when
cornering. The center of gravity
of AWD vehicles is higher than
conventional 2WD vehicles, making
them more likely to roll over when you
rapidly turn corners.

[Always hold the steering wheel firmly
when you are driving off-road.
WARNING
Do not grab the inside of the steering
wheel when you are driving off-road.
You may hurt your arm by a sudden
steering maneuver or from steering
wheel rebound due to an impact with
objects on the ground. You could lose
control of the steering wheel which may
lead to serious injury or death.
Emergency Precautions
Tires
When replacing tires, be sure to equip
all four tires with the same size, type,
tread patterns, brand and load-carrying
capacity.
WARNING
Do not use tire and wheel with different
size and type from the one originally
installed on your vehicle. It can affect
the safety and performance of your
vehicle, which could lead to steering
failure or rollover causing serious injury.
