Hazardous Driving Conditions
When hazardous driving elements
are encountered such as water, snow,
ice, mud and sand, take the below
suggestions:
• Drive cautiously and keep a longer braking distance.
• Avoid abrupt braking or steering.
• When your vehicle is stuck in snow, mud, or sand, use second
gear. Accelerate slowly to avoid
unnecessary wheel spin.
• Put sand, rock salt, tire chains or other non-slip materials under the wheels to
provide additional traction while the
vehicle becomes stuck in ice, snow,
or mud.
WARNING
Downshifting with an automatic
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.
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 R (Reverse)
and a forward gear.
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.
WARNING
If the vehicle is stuck and excessive
wheel spin occurs, the temperature
of the tires can increase very quickly.
If the tires become damaged, a tire
blow out or tire explosion can occur.
This condition is dangerous - you and
others may be injured. Do not attempt
this procedure if people or objects are
anywhere near the vehicle.
If you attempt to free the vehicle, the
vehicle can overheat quickly, possibly
causing an engine compartment fire
or other damage. Try to avoid spinning
the wheels as much as possible to
prevent overheating of either the tires
or the engine. DO NOT allow the vehicle
to spin the wheels above 35 mph (56
km/h).
Information
The ESC system must be turned OFF
before rocking the vehicle.
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 7.
SPECIAL DRIVING CONDITIONS

06
6-137
WARNING
The use of tire chains may adversely
affect vehicle handling:
• Drive less than 20 mph (30 km/h)
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.
Information
• Install tire chains on both left and right
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 studded tires without
first checking local, state and municipal
regulations for possible restrictions
against their use.
Chain installation
When installing tire chains, follow the
manuf
acturer’s instructions and mount
them as tightly possible. Drive slowly
(less than 20 mph (30 km/h)) 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 P
(Park), 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 0.3~0.6 miles
(0.5~1.0 km).
• Do not use tire chains on vehicles
equipped with aluminum wheels. If
unavoidable, use a wire type chain.
• Use wire chains less than 0.59 inch
(15mm) 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.

Certification label
OBH059070OBH059070
The certification label is located on the
driver’s door sill at the center pillar and
shows the maximum allowable weight of
the fully loaded vehicle. This is called the
GVWR (Gross Vehicle Weight Rating). The
GVWR includes the weight of the vehicle,
all occupants, fuel and cargo.
This label also tells you the maximum
weight that can be supported by the
front and rear axles, called Gross Axle
Weight Rating (GAWR).
The total weight of the vehicle, including
all occupants, accessories, cargo, and
trailer tongue load must not exceed the
Gross Vehicle Weight Rating (GVWR) or
the Gross Axle Weight Rating (GAWR).
To find out the actual loads on your front
and rear axles, you need to go to a weigh
station and weigh your vehicle. Be sure
to spread out your load equally on both
sides of the centerline.
WARNING
Overloading
• Never exceed the GVWR for your
vehicle, the GAWR for either the front
or rear axle and vehicle capacity
weight. Exceeding these ratings
can affect your vehicle’s handling
and braking ability, and cause an
accident.
• Do not overload your vehicle.
Overloading your vehicle can cause
heat buildup in your vehicle’s tires
and possible tire failure, increased
stopping distances and poor vehicle
handling-all of which may result in a
crash.
NOTICE
Overloading your vehicle may cause
damage. Repairs would not be covered
by your warranty. Do not overload your
vehicle.
WARNING
If you carry items inside your vehicle
(e.g., suitcases, tools, packages, or
anything else), they are moving as fast
as the vehicle. If you have to stop or
turn quickly, or if there is a crash, the
items will keep going and can cause
an injury if they strike the driver or a
passenger.
• Put items in the cargo area of your
vehicle. Try to spread the weight
evenly.
• Do not stack items, like suitcases,
inside the vehicle above the tops of
the seats.
• Do not leave an unsecured child
restraint in your vehicle.
• When you carry something inside the
vehicle, secure it.

Emergency Situations7-10
TPMS Malfunction
Indicator
The TPMS Malfunction Indicator
will illuminate after it blinks for
approximately one minute when there
is a problem with the Tire Pressure
Monitoring System.
Have the system checked by an
authorized HYUNDAI dealer as soon as
possible.
NOTICE
If there is a malfunction with the
TPMS, the individual tire pressures
in the cluster LCD display will not be
available. Have the system checked by
an authorized HYUNDAI dealer as soon
as possible.
NOTICE
The TPMS Malfunction Indicator may
illuminate after blinking for one minute
if the vehicle is near electric power
supply cables or radio transmitters
such as police stations, government
and public offices, broadcasting
stations, military installations, airports,
transmitting towers, etc.
Additionally, the TPMS Malfunction
Indicator may illuminate if snow chains
are used or electronic devices such as
computers, chargers, remote starters,
navigation, etc. This may interfere with
normal operation of the TPMS.
Changing a Tire with TPMS
If you have a flat tire, the Low Tire
Pressure and LCD position indicator will
come on. Have the flat tire repaired by an
authorized HYUNDAI dealer as soon as
possible or replace the flat tire with the
spare tire. (if equipped)
CAUTION
It is recommended that you do not use a
puncture-repairing agent not approved
by HYUNDAI dealer to repair and/or
inflate a low pressure tire. Tire sealant
not approved by HYUNDAI dealer may
damage the tire pressure sensor.
The spare tire does not come with a
tire pressure monitoring sensor. When
the low pressure tire or the flat tire is
replaced with the spare tire, the Low
Tire Pressure LCD position indicator will
remain on. Also, the TPMS Malfunction
Indicator will illuminate after blinking
for one minute if the vehicle is driven
at speed above 15.5 mph (25 km/h) for
approximately 20 minutes.
Once the original tire equipped with
a tire pressure monitoring sensor is
reinflated to the recommended pressure
and reinstalled on the vehicle, the Low
Tire Pressure LCD position indicator and
TPMS Malfunction Indicator will go off
within a few minutes of driving.
If the indicators do not disappear after a
few minutes, please visit an authorized
HYUNDAI dealer.

If you have a tire gauge, check the tire
pressure (see “Tires and Wheels” in
chapter 2 for tire pressure instructions.).
If the pressure is lower or higher than
recommended, drive slowly to the
nearest service station and adjust it to
the recommended pressure. Always
reinstall the valve cap after checking
or adjusting tire pressure. If the cap
is not replaced, air may leak from the
tire. If you lose a valve cap, buy another
and install it as soon as possible. After
changing tires, secure the flat tire and
return the jack and tools to their proper
storage locations. If it is hard to secure
the flat tire, put the flat tire in the
luggage compartment.
NOTICE
• Check the tire pressure as soon
as possible after installing a spare
tire. Adjust it to the recommended
pressure.
• Check and tighten the wheel lug
nuts after driving over 30 miles (50
km), after the spare tire is installed.
Recheck the tire wheel lug nuts after
driving over 620 miles (1,000 km)
after the replaced tire is reinstalled.
CAUTION
Your vehicle has metric threads on the
studs and lug nuts. Make certain during
tire changing that the same nuts that
were removed are reinstalled. If you
have to replace your lug nuts make
sure they have metric threads to avoid
damaging the studs and ensure the
wheel is properly secured to the hub.
Consult an authorized HYUNDAI dealer
for assistance.
If any of the equipment such as the jack,
lug nuts, studs, or other equipment is
damaged or in poor condition, do not
attempt to change the tire and call for
assistance.
Use of compact spare tires (if equipped)
Compact spare tires are designed for
emer

gency use only. Drive carefully on
the compact spare tire and always follow
the safety precautions.
WARNING
To prevent compact spare tire failure
and loss of control possibly resulting in
an accident:
• Use the compact spare tire only in an
emergency.
• NEVER operate your vehicle over 50
mph (80 km/h).
• Do not exceed the vehicle’s
maximum load rating or the load
carrying capacity shown on the
sidewall of the compact spare tire.
• Do not use the compact spare tire
continuously. Repair or replace the
original tire as soon as possible to
avoid failure of the compact spare
tire.

Emergency Situations7-16
When driving with the compact spare tire
mounted to your vehicle:
• Check the tire pressure after installing the compact spare tire. The compact
spare tire should be inflated to 60 psi
(420 kPa).
• Do not take this vehicle through an automatic car wash while the
compact spare tire is installed.
• Do not use the compact spare tire on any other vehicle because this tire
has been designed especially for your
vehicle.
• The compact spare tire’s tread life is shorter than a regular tire. Inspect
your compact spare tire regularly and
replace worn compact spare tires with
the same size and design, mounted on
the same wheel.
• Do not use more than one compact spare tire at a time.
NOTICE
When the original tire and wheel are
repaired and reinstalled on the vehicle,
the lug nut torque must be set correctly.
The correct lug nut tightening torque is
79~94 lbf·ft (11~13 kgf·m).
CAUTION
To prevent damaging the compact
spare tire and your vehicle:
• Drive slowly enough for the road
conditions to avoid all hazards, such
as a potholes or debris.
• Avoid driving over obstacles. The
compact spare tire diameter is
smaller than the diameter of a
conventional tire and reduces the
ground clearance approximately 1
inch (25 mm).
• Do not use tire chains on the
compact spare tire. Because of the
smaller size, a tire chain will not fit
properly.
• Do not use the compact spare tire
on any other wheels, nor should
standard tires, snow tires, wheel
covers or trim rings be used with the
compact spare wheel.
