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:
• Never place any portion of your body
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 button into P (Park)
or into R (Reverse) if equipped with
a manual transmission, 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.

the order shown above, but do not
remove any lug nuts until the tire has
been raised off of the ground.

TOWING
Towing Service
ODN8079010LODN8079010L[A] : Dollies
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.
On 2WD vehicles, 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.
CAUTION
• Do not tow the vehicle with the front
wheels on the ground as this may
cause damage to the vehicle.
ODN8079012LODN8079012L
• Do not tow with sling-type
equipment. Use a wheel lift or
flatbed equipment.

WARNING
If your vehicle is equipped with a
rollover sensor, place the ignition
switch in the LOCK/OFF or ACC position
when the vehicle is being towed.
The side impact and curtain air bag
may deploy if the sensor detects the
situation as a rollover.
When towing your vehicle in an
emergency without wheel dollies:
1. Place the ignition switch in the ACC position.
2. Place the shift button in N (Neutral).
3. Release the parking brake.
CAUTION
Failure to place the shift button in N
(Neutral) when being towed with the
front wheels on the ground can cause
internal damage to the transmission.
Emergency Towing
If towing is necessary, we recommend
you have it done by an authorized
HYUNDAI dealer or a commercial tow
truck service.
