Changing tires
WARNING
A vehicle can slip or roll off of a jack
causing serious injury or death to you
or those nearby. Take the following
safety precautions:
• Do not get under a vehicle that is
supported by a jack.
• NEVER attempt to change a tire in
the lane of traffic. ALWAYS move the
vehicle completely off the road on
level, firm ground away from traffic
before trying to change a tire. If you
cannot find a level, firm place off
the road, call a towing service for
assistance.
• Be sure to use the jack provided with
the vehicle.
• ALWAYS place the jack on the
designated jacking positions on the
vehicle and NEVER on the bumpers
or any other part of the vehicle for
jacking support.
• Do not start or run the engine while
the vehicle is on the jack.
• Do not allow anyone to remain in the
vehicle while it is on the jack.
• Keep children away from the road
and the vehicle.Follow these steps to change your
vehicle’s tire:
1. Park on a level, firm surface.
2. Move the shift lever into N (Neutral,
for Automated manual transmission
vehicle) or neutral (for manual
transmission vehicle), apply the
parking brake, and place the ignition
switch in the LOCK/OFF position.
3. Press the hazard warning flasher
button.
4. Remove the wheel lug nut wrench,
jack, jack handle, and spare tire from
the vehicle.
5. Block both the front and rear of the
tire diagonally opposite of the tire you
are changing.

6. Loosen the wheel lug nuts
counterclockwise one turn each in
the order shown above, but do not
remove any lug nuts until the tire has
been raised off of the ground.

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.
i Information
Check the tire pressure as soon as possible
after installing a spare tire. Adjust it to
the recommended pressure.
NOTICE
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. We recommend that you 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
emergency 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 80
km/h (50 mph).
• 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.

If emergency towing is necessary,
we recommend having it done by
an authorized HYUNDAI dealer or a
commercial tow-truck service. Proper
lifting and towing procedures are
necessary to prevent damage to the
vehicle. The use of wheel dollies or
flatbed is recommended.
It is acceptable to tow the vehicle with
the rear wheels on the ground (without
dollies) and the front wheels off the
ground. If any of the loaded wheels or
suspension components are damaged or
the vehicle is being towed with the front
wheels on the ground, use a towing dolly
under the front wheels.
When being towed by a commercial tow
truck and wheel dollies are not used, the
front of the vehicle should always be
lifted, not the rear.

NOTICE
• Do not tow the vehicle with 4 wheels
on the ground (such as dinghy towing
behind a motorhome or other motor
vehicle) as this can seriously damage
the Transmission.
OBI3080001OBI3080001
• Do not tow the vehicle with the front
wheels on the ground as this may
cause damage to the vehicle and the
Transmissions.
OBC3080016OBC3080016
• Do not tow with sling-type
equipment. Use a wheel lift or flatbed
equipment.

If towing is necessary, we recommend
you have it done by an authorized
HYUNDAI dealer or a commercial tow
truck service.
If towing service is not available in
an emergency, your vehicle may be
temporarily towed using a cable or chain
secured to the emergency towing hook
at the front (or rear) of the vehicle.
Use extreme caution when towing the
vehicle with a cable or chain. A driver
must be in the vehicle to steer it and
operate the brakes.
Towing in this manner may be done
only on hard-surfaced roads for a short
distance and at low speeds.
Also, the wheels, axles, power train,
steering and brakes must all be in good
condition.
CAUTION
The driver must be in the vehicle for
steering and braking operations when
the vehicle is being towed. Passengers
other than the driver must not be in the
vehicle.
Always follow these emergency towing
precautions:
• Place the ignition switch in the ACC
position so the steering wheel is not
locked.
• Place the shift lever in N (Neutral).
• Release the parking brake.
• Depress the brake pedal with more
force than normal since you will have
reduced braking performance.
• More steering effort will be required
because the power steering system
will be disabled.
• Use a vehicle heavier than your own to
tow your vehicle.
• The drivers of both vehicles should
communicate with each other
frequently.
• Before emergency towing, check that
the hook is not broken or damaged.
• Fasten the towing cable or chain
securely to the hook.
• Do not jerk the hook. Apply steady and
even force.

Maintenance
You should exercise the utmost care
to prevent damage to your vehicle and
injury to yourself whenever performing
any maintenance or inspection
procedures. Inadequate, incomplete
or insufficient servicing may result in
operational problems with your vehicle
that could lead to vehicle damage, an
accident, or personal injury.
Owner’s responsibility
i Information
Maintenance Service and Record
Retention are the owner’s responsibility.
We recommend in general that you have
your vehicle serviced by an authorized
HYUNDAI dealer.
You should retain documents that show
proper maintenance has been performed
on your vehicle in accordance with
the scheduled maintenance service
charts shown on the following pages.
You need this information to establish
your compliance with the servicing
and maintenance requirements of your
vehicle warranties.
Detailed warranty information is
provided in your Service Passport.
Repairs and adjustments required as
a result of improper maintenance or a
lack of required maintenance are not
covered when your vehicle is covered by
warranty.
Owner maintenance
precautions
Improper or incomplete service may
result in problems. This chapter gives
instructions only for the maintenance
items that are easy to perform.
i Information
Improper owner maintenance during the
warranty period may affect warranty
coverage. For details, read the separate
Service Passport provided with the
vehicle. If you’re unsure about any
servicing or maintenance procedure, we
recommend that the system be serviced by
an authorized HYUNDAI dealer.
WARNING
Maintenance work
• Performing maintenance work on a
vehicle can be dangerous. You can
be seriously injured while performing
some maintenance procedures.
If you lack sufficient knowledge
and experience or the proper tools
and equipment to do the work, we
recommend that the system be
serviced by an authorized HYUNDAI
dealer.
• Working under the hood with the
engine running is dangerous. It
becomes even more dangerous when
you wear jewelry or loose clothing.
These can become entangled in
moving parts and result in injury.
Therefore, if you must run the engine
while working under the hood, make
certain that you remove all jewelry
(especially rings, bracelets, watches,
and necklaces) and all neckties,
scarves, and similar loose clothing
before getting near the engine or
cooling fans.
