Engine Start/Stop Button (if equipped)
ODN8069001
Whenever the front door is opened, the
Engine Start/Stop button will illuminate
and will go off 30 seconds after the door is closed.
WARNING
To reduce risk of serious injury or death,
NEVER allow children or any person
who is unfamiliar with the vehicle to
touch the Engine Start/Stop button or
related parts. Unexpected and sudden
vehicle movement can occur.
WARNING
To turn the engine off in an emergency:
Press and hold the Engine Start/Stop
button for more than two seconds OR
rapidly press and release the Engine
Start/Stop button three times (within
three seconds).
If the vehicle is still moving, you can
restart the engine without depressing
the brake pedal by pressing the Engine
Start/Stop button with the shift button
in the N (Neutral) position.
WARNING
• NEVER press the Engine Start/Stop
button while the vehicle is in motion
except in an emergency. This will
result in the engine turning off and
loss of power assist for the steering
and brake systems.
This may lead to loss of directional
control and braking function, which
could cause an accident.
• Before leaving the driver's seat,
always make sure the shift button
is in the P (Park) position, set the
parking brake, press the Engine
Start/Stop button to the OFF
position, and take the Smart Key with
you. Unexpected vehicle movement
may occur if these precautions are
not followed.
• NEVER reach through the steering
wheel for the Engine Start/Stop
button or any other control while the
vehicle is in motion. The presence
of your hand or arm in this area
may cause a loss of vehicle control
resulting in an accident.

D (Drive)
This is the normal driving position. The
transmission will automatically shift
through a 8-gear sequence, providing
the best fuel economy and power.
To start the vehicle forward, push the D
(Drive) button by depressing the brake
pedal with the engine ON. Then depress
the accelerator pedal smoothly.
For extra power when passing another
vehicle or driving uphill, depress the
accelerator fully. The transmission will
automatically downshift to the next
lower gear (or gears, as appropriate).
When the vehicle is stopped in D (Drive)
position, if you open the driver's door
with the seat belt unfastened, the gear is
shifted to P (Park) position automatically.
However when the vehicle moves in D
(Drive) position, if you open the driver's
door with the seat belt unfastened, the
gear may not shift to P (Park) position
automatically to protect the automatic
transmission.
Shift-lock system
For your safety, the automatic
transmission has a shift-lock system
which prevents shifting the gear from
P (Park) or N (Neutral) to R (Reverse)
or D (Drive) unless the brake pedal is
depressed.
To shift the gear from P (Park) or N
(Neutral) to R (Reverse) or D (Drive):
1. Depress and hold the brake pedal.
2. Start the engine or place the ignition switch in the ON position.
3. Depress the brake pedal and push the R (Reverse) or D (Drive) button. Stay in N (Neutral) position when engine is Off
ODN8069006
ODN8069008
If you want to keep the N (Neutral)
position after the engine is OFF, do the
following.
1. Deactivate the AUTO HOLD and release the parking brake when the
ignition switch is ON.
2. Start the engine. Push the N (neutral) button while depressing the brake
pedal. If the message ("Press and
hold OK button to stay in Neutral
when vehicle is OFF") appears on the
cluster LCD display, press and hold
the OK button on the steering wheel
for more than 1 second.
3. When the message ("Vehicle will stay in (N). Change gear to cancel")
appears on the cluster LCD display,
turn off the engine.
In this situation, if you unfasten the
driver's seat belt and open the driver's
door within 3 minutes, the gear stays in
the N (Neutral) position and the ignition
switch is turned off.

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. Doing so may result
in an accident because of a loss of
engine braking and the transmission could be damaged.
• While driving up or downhill, check
the gear position, indicated on the
cluster, to ensure the vehicle is
driving forward while in D (Drive), or
backward while in R (Reverse). If you
drive in the opposite direction of the
selected gear, the engine will turn off
and a serious accident may occur due
to the 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.
• When driving in the manual shift
mode, slow down before shifting to a
lower gear. Otherwise, the lower gear
may not be engaged if the engine
rpms are outside of the allowable
range.
• Always apply the parking brake when
leaving the vehicle. Do not depend on
placing the transmission in P (Park) to
keep the vehicle from moving.
• Exercise extreme caution when
driving on a slippery surface. Be
especially careful when braking,
accelerating or shifting gears. On a
slippery surface, an abrupt change
in vehicle speed can cause the drive
wheels to lose traction and may cause
loss of vehicle control resulting in an
accident •
Optimum vehicle performance and
economy is obtained by smoothly
depressing and releasing the
accelerator.
WARNING
To reduce the risk of SERIOUS INJURY
or DEATH: • ALWAYS wear your seatbelt. In a
collision, an unbelted occupant
is significantly more likely to be
seriously injured or killed than a
properly belted occupant.
• 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 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.
• HYUNDAI recommends you follow all
posted speed limits.
Information
Kickdown Mechanism (if equipped)
If you depress the accelerator pedal equipped with Kickdown device beyond
the pressure point, it maximizes the engine
power. You may feel when the Kickdown
equipment starts to work and hear the sound of Kickdown operation. It is normal
operation, not a failure.

Power Brakes
Your vehicle has power-assisted brakes
that adjust automatically through normal usage.
If the engine 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 engine 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.
Only pump the brakes on slippery
surfaces if the power assist has been
interrupted to maintain steering control.
Do not pump the brakes on slippery
surfaces if the brakes are operating
normally.
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, move the gear shift button
to Manual Shift Mode 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.
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.
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.

While Driving
6-38
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 ignition
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.
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 HYUNDAI dealer as soon as possible.
CAUTION
When you drive on a road having poor
traction, such as an icy road, and apply
your brakes continuously, the ABS will
be active continuously and the ABS
warning light (
) may illuminate. Pull
your car over to a safe place and turn
the engine off.
Restart the engine. 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.

ESC OFF usage
When Driving
The ESC OFF mode should only be used
briefly to help free the vehicle if stuck in
snow by temporarily stopping operation
of the 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 transmission: • 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 engine power and do not
spin the wheel(s) excessively while
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 operation.
Vehicle Stability Management
(VSM)
The Vehicle Stability Management (VSM)
is a function of the Electronic Stability
Control (ESC) system. It helps ensure the
vehicle stays 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 the Vehicle Stability Management
(VSM): • ALWAYS check the speed and the
distance to the vehicle ahead. The
VSM is not a substitute for safe
driving practices.
• Never drive too fast for the road
conditions. The VSM system will not
prevent accidents. Excessive speed
in bad weather, slippery and uneven
roads can result in severe accidents.
VSM operation
VSM ON condition
The VSM operates when:
The Electronic Stability Control (ESC) is on.
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 sensation in the
brake pedal. This is normal and it means
your VSM is active.
NOTICE
The VSM does not operate when: • Driving on a banked road such as
gradient or incline.
• Driving rearward.
• ESC OFF indicator light is on.
• EPS (Electric Power Steering)
warning light (
) is on or blinks.

Brake operation •
In an urgent situation, the braking
system enters into the ready status for
prompt reaction against the driver’s
depressing the brake pedal.
• FCA provides additional braking
power for optimum braking
performance, when the driver
depresses the brake pedal.
• The braking control is automatically
deactivated, when the driver sharply
depresses the accelerator pedal, or
when the driver abruptly operates the
steering wheel.
• FCA brake control is automatically
canceled, when risk factors disappear.
CAUTION
• The driver should always use
extreme caution while operating
the vehicle, whether or not there is a
warning message or alarm from FCA
system.
• After the brake control is activated,
the driver must immediately depress
the brake pedal and check the
surroundings. The brake activation
by the system lasts for about 2
seconds.
• If any other warning sound such as
seat belt warning chime is already
generated, Forward Collision-
Avoidance Assist system warning
may not sound.
• Playing the vehicle audio system at
high volume may prevent occupants
from hearing the system warning sounds.
WARNING
The braking control cannot completely
stop the vehicle nor avoid all
collisions. The driver should hold the
responsibility to safely drive and control
the vehicle.
WARNING
The FCA system logic operates within
certain parameters, such as the
distance from the vehicle, pedestrian or
cyclist (if equipped) ahead, the speed
of the vehicle ahead, and the driver’s
vehicle speed. Certain conditions
such as inclement weather and road
conditions may affect the operation of
FCA system.
WARNING
Never deliberately drive dangerously to
activate the system.
Information
Exceptional operation of the braking assist system • The vehicle drives on a slope or curve.
• The vehicle drives by a pedestrian or
cyclist at the crossroads, traffic signals
or structure.
• The vehicle drives through a tunnel or
near a railroad.
• The vehicle drives where steam, smoke
or shadow is on the road.
• The vehicle drives the road tree planted
or streetlamps installed.
• There is interference by
electromagnetic waves or electric noise.
