turning the engine off.
WARNING
• Shifting into P (Park) while the
vehicle is in motion may cause you to
lose control of the vehicle.
• After the vehicle has stopped, always
make sure the shift lever is in P (Park),
apply the parking brake, and turn the
engine off.
• When parking on an incline, block the
wheels to prevent the vehicle from
rolling down.
• For safety, always engage the parking
brake with the shift lever in the P
(Park) position except for the case of

Parking
Always come to a complete stop and
continue to depress the brake pedal.
Move the shift lever into the P (Park)
position, apply the parking brake, and
place the ignition switch in the LOCK/
OFF position. Take the Key with you
when exiting the vehicle.
WARNING
When you stay in the vehicle with
the engine running, be careful not to
depress the accelerator pedal for a long
period of time. The engine or exhaust
system may overheat and start a fire.
The exhaust gas and the exhaust
system are very hot. Keep away from
the exhaust system components.
Do not stop or park over flammable
materials, such as dry grass, paper or
leaves. They may ignite and cause a
fire.
Good driving practices
• Never move the shift lever from P
(Park) or N (Neutral) to any other
position with the accelerator pedal
depressed.
• Never move the shift lever 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 move the shift lever 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.
• Driving uphill or downhill, always shift
to D (Drive) when driving forward or to
R (Reverse) when driving backwards,
and check the gear position indicated
on the cluster before driving. If you
drive in the opposite direction of the
selected gear, the engine will turn
off and a serious accident might be
occurred 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.
• Depressing both accelerator and brake
pedals at the same time can trigger
logic for engine power reduction to
assure vehicle deceleration. Vehicle
acceleration will resume after the
brake pedal is released.
• When driving in 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.

Driving your vehicle
WARNING
To reduce the risk of serious injury or
death:
• ALWAYS check the surrounding
areas near your vehicle for people,
especially children, before shifting a
vehicle into D (Drive) or R (Reverse).
• Before leaving the driver’s seat,
always make sure the shift lever
is in the P (Park) position, then set
the parking brake, and place the
ignition switch in the LOCK/OFF
position. Unexpected and sudden
vehicle movement can occur if these
precautions are not followed.
• When using Manual Shift Mode, do
not use engine braking (shifting from
a high gear to lower gear) rapidly on
slippery roads. The vehicle may slip
causing an accident.

• 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.

• NEVER allow anyone who is
unfamiliar with the vehicle to touch
the parking brake. If the parking
brake is released unintentionally,
serious injury may occur.
• Only release the parking brake when
you are seated inside the vehicle with
your foot firmly on the brake pedal.
NOTICE
• Do not apply the accelerator pedal
while the parking brake is engaged.
If you depress the accelerator pedal
with the parking brake engaged,
warning will sound. Damage to the
parking brake may occur.
• Driving with the parking brake on
can overheat the braking system and
cause premature wear or damage to
brake parts. Make sure the parking
brake is released and the Brake
Warning Light is off before driving.
Parking brake warning light
Check the Parking Brake
Warning Light by placing the
ignition switch to the ON
position (do not start the
engine).
This light will be illuminated when the
parking brake is applied with the ignition
switch in the START or ON position.
Before driving, be sure the parking brake
is released and the Brake Warning Light
is OFF.
If the Parking Brake Warning Light
remains on after the parking brake is
released while the engine is running,
there may be a malfunction in the
brake system. Immediate attention is
necessary.
If at all possible, cease driving the
vehicle immediately. If that is not
possible, use extreme caution while
operating the vehicle and only continue
to drive the vehicle until you can reach a
safe location.

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, we recommend that
you contact your 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, the ABS will
be active continuously and the ABS
warning light (
) may illuminate. Pull
your vehicle 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. We recommend
that you contact an authorized
HYUNDAI dealer as soon as possible.
i 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) (if equipped)
OBI3060006OBI3060006
The Electronic Stability Control (ESC)
system 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 engine management 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 or too quickly when
cornering. The ESC system will not
prevent accidents.
Excessive speed in turns, abrupt
maneuvers, and hydroplaning on wet
surfaces can result in severe accidents.

light illuminates we recommend that
the vehicle be checked by an authorized
HYUNDAI dealer as soon as possible.
The ESC OFF indicator light comes on
when the ESC is turned off with the
button.
WARNING
When the ESC is blinking, this indicates
the ESC is active:
Drive slowly and NEVER attempt to
accelerate. NEVER turn the ESC off
while the ESC indicator light is blinking
or you may lose control of the vehicle
resulting in an accident.
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 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).
i Information
Turning the ESC off does not affect ABS
or standard brake system operation.
Vehicle Stability Management
(VSM) (if equipped)
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.
