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.

Driving your vehicle
Emergency Stop Signal (ESS)
The Emergency Stop Signal system
alerts the driver behind by blinking the
stop light when the vehicle is braked
rapidly and severely.
The system is activated when:
• The vehicle suddenly stops (vehicle
speed is over 55 km/h and the vehicle
deceleration at greater than 7 m/s
2)
• The ABS is activating
When the vehicle speed is under 40
km/h and the ABS deactivates or the
sudden stop situation is over, the stop
light blinking will stop. Instead, the
hazard warning flasher will turn on
automatically.
The hazard warning flasher will turn off
when vehicle speed is over 10 km/h after
the vehicle has stopped. Also, it will turn
off when the vehicle is driven at low
speed for some time. You can turn it off
manually by pushing the hazard warning
flasher switch.
CAUTION
The Emergency Stop Signal (ESS)
system will not work if the hazard
warning flasher is already on.
Good braking practices
WARNING
Whenever leaving the vehicle or
parking, always come to a complete
stop and continue to depress the brake
pedal. Move the shift lever into the 1st
gear (for manual transmission vehicle)
or N (Neutral) position (for Automated
Manual Transmission vehicle), then
apply the parking brake, and place
the ignition switch in the LOCK/OFF
position.
Vehicles with the parking brake not
fully engaged are at risk for moving
inadvertently and causing injury to
yourself or others.
Wet brakes can be dangerous! 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, taking care to keep the vehicle
under control at all times. If the braking
action does not return to normal, stop
as soon as it is safe to do so and we
recommend that you 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.

Driving your vehicle
Hazardous driving conditions
When hazardous driving conditions are
encountered such as water, snow, ice,
mud or sand:
Drive cautiously and allow extra distance
for braking.
Avoid sudden movements in braking or
steering.
If stuck in snow, mud, or sand, use
second gear. Accelerate slowly to avoid
spinning the drive wheels.
WARNING
Downshifting with an Automated
manual transmission, while driving
on slippery surfaces can cause an
accident. The sudden change in tire
speed could cause the tires to skid. Be
careful when downshifting on slippery
surfaces.
Use sand, rock salt, or other non-slip
material under the drive wheels to
provide traction when stalled in ice,
snow, or mud.
Rocking the vehicle
If it is necessary to rock the vehicle to
free it from snow, sand, or mud, first
turn the steering wheel right and left
to clear the area around your front
wheels. Then, shift back and forth
between 1st and R (Reverse, for manual
transmission vehicle) or R (Reverse) and
a forward gear (for Automated manual
transmission vehicle). Try to avoid
spinning the wheels, and do not race the
engine.
To prevent transmission wear, wait until
the wheels stop spinning before shifting
gears. Release the accelerator pedal
while shifting, and press lightly on the
accelerator pedal while the transmission
is in gear. Slowly spinning the wheels in
forward and reverse directions causes
a rocking motion that may free the
vehicle.
NOTICE
If the tires spin at high speed the tires
can explode, and you or others may be
injured. Do not attempt this procedure
if people or objects are anywhere near
the vehicle.
The vehicle can overheat causing an
engine compartment fire or other
damage. Spin the wheels as little as
possible and avoid spinning the wheels
at speeds over 56 km/h (35 mph) as
indicated on the speedometer.
NOTICE
If you are still stuck after rocking the
vehicle a few times, have the vehicle
pulled out by a tow vehicle to avoid
engine overheating, possible damage
to the transmission, and tire damage.
See “Towing” in chapter 8.

Driving your vehicle
Don’t let your parking brake freeze
Under some conditions your parking
brake can freeze in the engaged
position. This is most likely to happen
when there is an accumulation of snow
or ice around or near the rear brakes or
if the brakes are wet. If there is a risk
the parking brake may freeze, apply
it only temporarily while you put the
shift lever in N (for Automated Manual
Transmission) or in first or reverse gear
(for manual transmission) and block the
rear wheels so the vehicle cannot roll.
Then release the parking brake.
Don’t let ice and snow accumulate
underneath
Under some conditions, snow and ice
can build up under the fenders and
interfere with the steering. When driving
in severe winter conditions where this
may happen, you should periodically
check underneath the car to be sure the
movement of the front wheels and the
steering components is not obstructed.
Carry emergency equipment
Depending on the severity of the
weather, you should carry appropriate
emergency equipment. Some of the
items you may want to carry include tire
chains, tow straps or chains, flashlight,
emergency flares, sand, shovel, jumper
cables, window scraper, gloves, ground
cloth, coveralls, blanket, etc.
Don’t place foreign objects
or materials in the engine
compartment
Placement of foreign objects or
materials which prevent cooling of the
engine, in the engine compartment,
may cause a failure or combustion. The
manufacturer is not responsible for the
damage caused by such placement.

Emergency situations
OAI3079001OAI3079001
The hazard warning flasher serves as
a warning to other drivers to exercise
extreme caution when approaching,
overtaking, or passing your vehicle.
It should be used whenever emergency
repairs are being made or when the
vehicle is stopped near the edge of a
roadway.
To turn the hazard warning flasher on
or off, press the hazard warning flasher
button with the ignition switch in any
position. The button is located in the
crash pad garnish panel.
All turn signal lights will flash
simultaneously.
• The hazard warning flasher operates
whether your vehicle is running or not.
• The turn signals do not work when the
hazard flasher is on.
HAZARD WARNING FLASHER IN CASE OF AN EMERGENCY
WHILE DRIVING
If the engine stalls while driving
• Reduce your speed gradually, keeping
a straight line. Move cautiously off the
road to a safe place.
• Turn on your hazard warning flasher.
• Try to start the engine again. If your
vehicle will not start, we recommend
that you contact an authorized
HYUNDAI dealer.
If the engine stalls at a
crossroad or crossing
If the engine stalls at a crossroad or
crossing, if safe to do so, move the shift
lever to the N (Neutral) position and then
push the v ehicle to a safe location.
• If your vehicle has a manual

If you have a flat tire while
driving
If a tire goes flat while you are driving:
• Take your foot off the accelerator
pedal and let the vehicle slow down
while driving straight ahead. Do not
apply the brakes immediately or
attempt to pull off the road as this
may cause loss of vehicle control
resulting in an accident. When the
vehicle has slowed to such a speed
that it is safe to do so, brake carefully
and pull off the road. Drive off the
road as far as possible and park on
firm, level ground. If you are on a
divided highway, do not park in the
median area between the two traffic
lanes.
• When the vehicle is stopped, press
the hazard warning flasher button,
move the shift lever into N (Neutral,
for Automated manual transmission)
or neutral (for manual transmission
vehicle), apply the parking brake, and
place the ignition switch in the LOCK/
OFF position.
• Have all passengers get out of the
vehicle. Be sure they all get out on the
side of the vehicle that is away from
traffic.
• When changing a flat tire, follow the
instructions provided later in this
chapter.
IF THE ENGINE WILL NOT
START
If the engine doesn’t turn over
or turns over slowly
• Be sure the for Automated manual
transmission or N (Neutral) if it is a
vehicle. The engine starts only when
the shift lever is in N (Neutral).
• Check the battery connections to be
sure they are clean and tight.
• Turn on the interior light. If the light
dims or goes out when you operate
the starter, the battery is drained.
Do not push or pull the vehicle to start
it. This could cause damage to your
vehicle.
See instructions for “Jump Starting”
provided in this chapter.
WARNING
Push or pull starting the vehicle may
cause the catalytic converter to
overload which can lead to damage to
the emission control system.
If the engine turns over normally
but doesn’t start
• Check the fuel level and add fuel if
necessary.
If the engine still does not start, we
recommend that you call an authorized
HYUNDAI dealer for assistance.

If your temperature gauge indicates
overheating, you experience a loss of
power, or hear loud pinging or knocking,
the engine may be overheating. If this
happens, you should:
1. Pull off the road and stop as soon as it
is safe to do so.
2. Place the shift lever in N (Neutral,
for Automated manual transmission
vehicle) or neutral (for manual
transmission vehicle) and set the
parking brake. If the air conditioning is
ON, turn it OFF.
3. If engine coolant is running out under
the vehicle or steam is coming out
from the hood, stop the engine. Do
not open the hood until the coolant
has stopped running or the steaming
has stopped. If there is no visible
loss of engine coolant and no steam,
leave the engine running and check
to be sure the engine cooling fan is
operating. If the fan is not running,
turn the engine off.
WARNING
While the engine is running,
keep hands, clothing and
tools away from the moving
parts such as the cooling
fan and drive belt to
prevent serious injury.4. Check for coolant leaking from the
radiator, hoses or under the vehicle. (If
the air conditioning had been in use, it
is normal for cold water to be draining
from it when you stop.)
5. If engine coolant is leaking out,
stop the engine immediately and
we recommend that you call an
authorized HYUNDAI dealer for
assistance.
WARNING
NEVER remove the radiator
cap or the drain plug while
the engine and radiator are
hot. Hot coolant and steam
may blow out under
pressure, causing serious injury.
Turn the engine off and wait until the
engine cools down. Use extreme care
when removing the radiator cap. Wrap
a thick towel around it, and turn it
counterclockwise slowly to the first
stop. Step back while the pressure
is released from the cooling system.
When you are sure all the pressure
has been released, press down on the
cap, using a thick towel, and continue
turning counterclockwise to remove it.
