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 button into P (Park),
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.

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.

Towing service
OTMH080014[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.
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
OTM080013
• Do not tow with sling-type
equipment. Use wheel lift or flatbed
equipment.
OTMH080009
• Do not tow the vehicle with the front
wheels on the ground as this may
cause damage to the vehicle.
When towing your vehicle in an
emergency without wheel dollies:
• Vehicle without EPB
1. Place the ignition switch in the ACC
position.
2. Place the shift button in N (Neutral).
3. Release the parking brake.
• Vehicle with EPB
1. Release EPB before turning off the
engine.
2. Place the ignition switch to the OFF
position.
3. Change the gear to N (Neutral) while
pressing the brake pedal.
4. Place the ignition switch to the ACC
position.
CAUTION
Failure to place the shift button in N
(Neutral) may cause internal damage to
the transmission.

Emergency towing
„„Front
OTM080017
„„Rear
OTM080018
If towing is necessary, we recommend
you have it done by an authorized
HYUNDAI dealer or a commercial tow
truck service.
If a 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 button in N (Neutral).
• Release the parking brake.
• Depress the brake pedal with more
force than normal as 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.

We recommend that you consult an
authorized HYUNDAI dealer to replace
most vehicle light bulbs. It is difficult
to replace vehicle light bulbs because
other parts of the vehicle must be
removed before you can get to the bulb.
This is especially true for removing the
headlamp assembly to get to the bulb(s).
Removing/installing the headlamp
assembly can result in damage to the
vehicle.
WARNING
• Prior to working on a light, depress
the foot brake, shift to P (Park), apply
the parking brake, set the ignition
switch to the LOCK/OFF position
and take the key with you when
leaving the vehicle to avoid sudden
movement of the vehicle and to
prevent possible electric shock.
• Be aware the bulbs may be hot and
may burn your fingers.
NOTICE
Be sure to replace the burned-out bulb
with one of the same wattage rating.
Otherwise, it may cause damage to the
fuse or electrical wiring system.
NOTICE
To prevent damage, do not clean the
headlamp lens with chemical solvents
or strong detergents.
Information
The headlamp and tail lamp lenses could
appear frosty if the vehicle is washed after
driving or the vehicle is driven at night
in wet weather. This condition is caused
by temperature difference between the
lamp inside and outside and, it does not
indicate a problem with your vehicle.
When moisture condenses in the lamp,
it will be removed after driving with the
headlamp on. The removable level may
differ depending on lamp size, lamp
position and environmental condition.
However, if moisture is not removed, we
recommend that your vehicle is inspected
by an authorized HYUNDAI dealer.
Information
• A normally functioning lamp may
flicker momentarily to stabilize the
vehicle’s electrical control system.
However, if the lamp goes out after
flickering momentarily, or continues to
flicker, we recommend the system be
checked by an authorized HYUNDAI
dealer.
• The position lamp may not turn on
when the position lamp switch is turned
on, but the position lamp and headlamp
switch may turn on when the headlamp
switch is turned on. This may be caused
by network failure or vehicle electrical
control system malfunction. If this
occurs, we recommend the system be
checked by an authorized HYUNDAI
dealer.
Information
The headlamp aiming should be adjusted
after an accident or after the headlamp
assembly is reinstalled at an authorized
HYUNDAI dealer.
