Emergency Towing
B0414KO01
A: Front
B0414KO02
B: Rear
If towing is necessary, 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 working
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 or press the
Engine Start/Stop button to the ACC
position so the steering wheel is not
locked.

[ Shift the gear to 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.

Information
The coolant level is influenced by the
engine temperature. Before checking or
refilling the coolant, turn the engine off.
WARNING
The electric motor for the
cooling fan may continue to
operate or start up when the
engine is not running and can
cause serious injury. Keep
hands, clothing and tools away
from the rotating fan blades of
the cooling fan.
Always turn off the vehicle unless the
vehicle has to be inspected with the
engine on. Be cautious as the cooling
fan may operate if the negative (-)
battery terminal is not disconnected.
WARNING
Make sure the coolant cap is properly
closed after refilling coolant. Otherwise
the engine could be overheated whilst
driving.

NOTICE
Always follow these instructions when
handling your vehicle’s battery to
prevent damage to your battery:

[ When you do not use the vehicle for a
long time in a low temperature area,
disconnect the battery and keep it
indoors.

[ Always charge the battery fully to
prevent battery case damage in low
temperature areas.

[ Prevent liquid from wetting the
battery terminals. The performance
of the battery may be degraded, and
may cause injury. Be cautious when
loading liquid in the liftgate.

[ Do not tilt the battery.

[ If you connect unauthorized
electronic devices to the battery, the
battery may be discharged. Never
use unauthorized devices.
For Best Battery Service
B0455KO01

[Keep the battery securely mounted.

[ Keep the battery top clean and dry.

[ Keep the terminals and connections
clean, tight, and coated with
petroleum jelly or terminal grease.

[ Rinse any spilled acid from the battery
immediately with a solution of water
and baking soda.
Information
For vehicles with power liftgate, note that
the power liftgate needs to be reset after
the battery has been replaced. For more
details, refer to “ Power Liftgate “ section
in chapter 5.

Replacement
Blade fuse/Cartridge fuse
B0468KO03
B0468KO04
A: Blade type, B: Cartridge type
1. Turn the vehicle off.
2. Turn all other switches off.
3. Remove the fuse panel cover by
pressing the tap and pulling up.
4. Check the removed fuse; replace it if it is blown. To remove or insert the
fuse, use the fuse puller in the engine

authorized HYUNDAI dealer.
NOTICE
After checking the fuse panel in the
engine compartment, securely install
the fuse panel cover. You may hear a
clicking sound if the cover is securely
latched. If it is not securely latched,
electrical failure may occur from water
contact.
Multi fuse
B0468KO02
If the multi fuse is blown, it must be
removed as follows:
1. Turn off the engine.
2. Disconnect the negative battery cable.
3. Remove the fuse panel cover by pressing the tab and pulling it up.
4. Remove the nuts shown in the picture above.
5. Replace the fuse with a new one of the same rating.
6. Reinstall in the reverse order of removal.
Information
If the multi fuse is blown, consult an
authorized HYUNDAI dealer.
