When the ignition switch is in the
ON position, the ESC indicator light
illuminates, then goes off if the ESC
system is operating normally.
The ESC indicator light blinks whenever
the ESC is operating.
If the ESC indicator light stays on, your
vehicle may have a malfunction with
the ESC system. When this warning
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.

Snow or icy conditions
You need to keep sufficient distance
between your vehicle and the vehicle in
front of you.
Apply the brakes gently. Speeding, rapid
acceleration, sudden brake applications,
and sharp turns are potentially
very hazardous practices. During
deceleration, use engine braking to the
fullest extent. Sudden brake applications
on snowy or icy roads may cause skids
to occur.
To drive your vehicle in deep snow, it
may be necessary to use snow tires or to
install tire chains on your tires.
Always carry emergency equipment.
Some of the items you may want to
carry include tire chains, tow straps or
chains, a flashlight, emergency flares,
sand, a shovel, jumper cables, a window
scraper, gloves, ground cloth, coveralls,
a blanket, etc.
Snow tires
WARNING
Snow tires should be equivalent in size
and type to the vehicle’s standard tires.
Otherwise, the safety and handling of
your vehicle may be adversely affected.
If you mount snow tires on your vehicle,
make sure to use radial tires of the same
size and load range as the original tires.
Mount snow tires on all four wheels
to balance your vehicle’s handling in
all weather conditions. The traction
provided by snow tires on dry roads
may not be as high as your vehicle’s
original equipment tires. Check with
the tire dealer for maximum speed
recommendations.
We recommend you use snow tires
when road temperature is below 45°F
(7°C).
i Information
Do not install studded tires without first
checking local and municipal regulations
for possible restrictions against their use.
Tire chains
OBI3060007LOBI3060007L
Since the sidewalls of radial tires are
thinner than other types of tires, they
may be damaged by mounting some
types of tire chains on them. Therefore,
the use of snow tires is recommended
instead of tire chains. Do not mount
tire chains on vehicles equipped with
aluminum wheels; if unavoidable use
a wire type chain. If tire chains must
be used, use genuine HYUNDAI parts
and install the tire chain after reviewing
the instructions provided with the tire
chains. Damage to your vehicle caused
by improper tire chain use is not covered
by your vehicle manufacturer’s warranty.
WINTER DRIVING

7-52
Driving your vehicle
WARNING
The use of tire chains may adversely
affect vehicle handling:
• Drive less than 30 km/h (20 mph)
or the chain manufacturer’s
recommended speed limit,
whichever is lower.
• Drive carefully and avoid bumps,
holes, sharp turns, and other road
hazards, which may cause the vehicle
to bounce.
• Avoid sharp turns or locked wheel
braking.
i Information
• Install tire chains on the front tires.
It should be noted that installing
tire chains on the tires will provide
a greater driving force, but will not
prevent side skids.
• Do not install tire chains without
first checking local and municipal
regulations for possible restrictions
against their use.
Chain Installation
When installing tire chains, follow the
manufacturer’s instructions and mount
them as tightly possible. Drive slowly
(less than 30 km/h (20 mph)) with
chains installed. If you hear the chains
contacting the body or chassis, stop and
tighten them. If they still make contact,
slow down until the noise stops. Remove
the tire chains as soon as you begin
driving on cleared roads.
When mounting snow chains, park
the vehicle on level ground away from
traffic. Turn on the vehicle Hazard
Warning Flasher and place a triangular
emergency warning device behind the
vehicle (if available). Always place the
vehicle in N (Neutral), apply the parking
brake and turn off the engine before
installing snow chains.
NOTICE
When using tire chains:
• Wrong size chains or improperly
installed chains can damage your
vehicle’s brake lines, suspension,
body and wheels.
• Use SAE “S” class or wire chains.
• If you hear noise caused by chains
contacting the body, retighten the
chain to prevent contact with the
vehicle body.
• To prevent body damage, retighten
the chains after driving 0.5~1.0 km
(0.3~0.6 miles).
• Do not use tire chains on vehicles
equipped with aluminum wheels. If
unavoidable, use a wire type chain.
• Use wire chains less than 15 mm (0.59
in) wide to prevent damage to the
chain’s connection.

Winter precautions
Use high quality ethylene glycol
coolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because it
helps prevent corrosion in the cooling
system, lubricates the water pump and
prevents freezing. Be sure to replace or
replenish your coolant in accordance
with the maintenance schedule in
chapter 8. Before winter, have your
coolant tested to assure that its freezing
point is sufficient for the temperatures
anticipated during the winter.
Check battery and cables
Winter puts additional burdens on the
battery system. Visually inspect the
battery and cables as described in
chapter 8. The level of charge in your
battery can be checked by an authorized
HYUNDAI dealer or a service station.
Change to “winter weight” oil if
necessary
In some climates it is recommended that
a lower viscosity “winter weight” oil be
used during cold weather. See chapter
2 for recommendations. If you aren’t
sure what weight oil you should use, we
recommend that you consult with an
authorized HYUNDAI dealer.
Check spark plugs and ignition
system
Inspect your spark plugs as described
in chapter 8 and replace them if
necessary. Also check all ignition wiring
and components to be sure they are not
cracked, worn or damaged in any way.
To keep locks from freezing
To keep the locks from freezing, squirt
an approved de-icer fluid or glycerine
into the key opening. If a lock is covered
with ice, squirt it with an approved
de-icing fluid to remove the ice. If the
lock is frozen internally, you may be able
to thaw it out by using a heated key.
Handle the heated key with care to avoid
injury.
Use approved window washer anti-
freeze in system
To keep the water in the window washer
system from freezing, add an approved
window washer anti-freeze solution in
accordance with instructions on the
container. Window washer anti-freeze is
available from an authorized HYUNDAI
dealer and most auto parts outlets. Do
not use engine coolant or other types
of anti-freeze as these may damage the
paint finish.

7-54
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.

System malfunction and
precautions
System malfunction
After starting the engine, a beep will
sound when the gear is shifted to R
(Reverse) to indicate the system is
operating normally.
However, if one or more of the following
occurs, first check whether the
ultrasonic sensor is damaged or blocked
with foreign material. If it still does not
work properly, we recommend that the
system be inspected by an authorized
HYUNDAI dealer.
• The audible warning does not sound.
• The buzzer sounds intermittently.
• The ‘Sensor error or blockage. System
limited’ warning message appears on
the cluster.

WARNING
• Reverse Parking Distance Warning
is a supplemental system. The
operation of the system can be
affected by several factors (including
environmental conditions). It is the
responsibility of the driver to always
check the rear view before and while
parking.
• Your new vehicle warranty does not
cover any accidents or damage to
the vehicle due to the malfunction of
Reverse Parking Distance Warning.
• Pay close attention when driving near
objects, pedestrians, and especially
children. Some objects may not be
detected by the ultrasonic sensors,
due to the objects distance, size or
material, all of which can limit the
effectiveness of the sensor.
Limitations of the system
• Reverse Parking Distance Warning
may not operate normally when:
- Moisture is frozen to the sensor
- Sensor is covered with foreign
material, such as snow or water (The
system will operate normally when
such foreign material are removed.)
- The weather is extremely hot or cold
- The sensor or sensor assembly is
disassembled
- The surface of the sensor is pressed
hard or an impact is applied with a
hard object
- The surface of the sensor is
scratched with a sharp object
- The sensors or its surrounding area is
directly sprayed with high pressure

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.
