Emergency towing
If towing is necessary, we recom-
mend you have it done by an autho-
rised HYUNDAI dealer or a commer-
cial 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 tow-
ing 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.
To w i n g i n t h i s m a n n e r m a y b e d o n e
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.
Always follow these emergency tow-
ing 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 nor mal 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 fre-
quently.
•Before emergency towing, check
that the hook is not broken or dam-
aged.
•Fasten the towing cable or chain
securely to the hook.
•Do not jerk the hook.Apply steady
and even force.

Checking the parking brake
Check the stroke of the parking
brake by counting the number of
“clicks’’ heard whilst fully applying it
from the released position. Also, the
parking brake alone should securely
hold the vehicle on a fairly steep
grade. If the stroke is more or less
than specified, we recommend that
the system be serviced by an autho-
rised HYUNDAI dealer.
Stroke : 5~6 “clicks’’ at a force of
20 kg (44 lbs, 196 N).

For best battery service
•Keep the battery securely mounted.
•Keep the battery top clean and dry.
•Keep the terminals and connec-
tions clean, tight, and coated with
petroleum jelly or terminal grease.
•Rinse any spilled electrolyte from
the battery immediately with a
solution of water and baking soda.
•If the vehicle is not going to be
used for an extended time, discon-
nect the battery cables.
Information
The battery, which is originally
installed in your vehicle, is mainte-
nance free. However, your vehicle is
equipped with a battery marked with
LOWER and UPPER on the side for
you to check the electrolyte level.
The electrolyte level should be
between LOWER and UPPER. When
the electrolyte level is low, add dis-
tilled (or de-mineralised) water.
(Never add sulfuric acids or other
electrolyte).
Be careful not to spill distilled (or
demineralised) water over the battery
surface or other adjacent components.
Also, do not overfill the battery cells
as it may corrode the battery or other
components. Finally, securely close
the cell cap. However, we recommend
you to contact an authorised
HYUNDAI dealer for better battery
service.

To p r e v e n t S E R I O U S I N J U RY o r
DEATH to you or bystanders,
always follow these precautions
when working near or handling
the battery:
Always read and follow
instructions carefully
when handling a battery.
Wear eye protection
designed to protect the
eyes from acid splashes.
Keep all flames, sparks,
or smoking materials
away from the battery.
Hydrogen is always
present in battery cells,
is highly combustible,
and may explode if ignit-
ed.
Keep batteries out of
reach of children.

Engine compartment panel fuse
replacement
1. Turn the engine off.
2. Turn all the switches off.
3. Remove the fuse box cover by
pressing the tab 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 compartment fuse panel.
5. Push in a new fuse of the same
rating, and make sure it fits tightly
in the clips. If it fits loosely, we rec-
ommend that you consult an
authorised HYUNDAI dealer.
After checking the fuse box in the
engine compartment, securely
install the fuse box cover. If not,
electrical failures may occur from
water leaking in.
Main fuse
If an electrical system does not oper-
ate with no blown fuse in the engine
compartment and inner fuse box, the
main fuse inside the battery (+) cap
may be blown.
The main fuse is heavily connected
to many other parts. In this case, we
recommend you to contact an autho-
rised HYUNDAI dealer.
