Driving your vehicle
Safety chains
You should always attach chains
between your vehicle and your trail-
er. Cross the safety chains under the
tongue of the trailer so that the
tongue will not drop to the road if it
becomes separated from the hitch.
Instructions about safety chains may
be provided by the hitch manufactur-
er or trailer manufacturer. Follow the
manufacturer's recommendation for
attaching safety chains. Always leave
just enough slack so you can turn
with your trailer. And, never allow
safety chains to drag on the ground.
Trailer brakes
If your trailer is equipped with a brak-
ing system, make sure it conforms to
federal and/or local regulations and
that it is properly installed and oper-
ating correctly.
If your trailer weighs more than the
maximum trailer weight without trail-
er brakes loaded, then it needs its
own brakes and they must be ade-
quate. Be sure to read and follow the
instructions for the trailer brakes so
you’ll be able to install, adjust and
maintain them properly. Do not tap
into your vehicle's brake system.
Trailer brakes must be applied sepa-
rately from your vehicle's brake sys-
tem.
Driving with a trailer
Towing a trailer requires a certain
amount of experience. Before setting
out for the open road, you must get
to know your trailer. Acquaint your-
self with the feel of handling and
braking with the added weight of the
trailer. And always keep in mind that
the vehicle you are driving is now
longer and not nearly as responsive
as your vehicle is by itself.
Before you start, check the trailer
hitch and platform, safety chains,
electrical connector(s), lights, tires
and brakes.
During your trip, occasionally check
to be sure that the load is secure,
and that the lights and trailer brakes
are still working.
Do not use a trailer with its own
brakes unless you are absolute-
ly certain that you have properly
set up the brake system. Use an
experienced, competent trailer
shop for this work.

2. Slowly remove your foot from the
brake pedal.
3. Drive slowly until the trailer is clear
of the chocks.
4. Stop and have someone pick up
and store the chocks.
Maintenance when trailer tow-
ing
Your vehicle will need service more
often when you regularly pull a trail-
er. Important items to pay particular
attention to include engine oil, auto-
matic transmission fluid, axle lubri-
cant and cooling system fluid. Brake
condition is another important item to
frequently check. If you're trailering,
it’s a good idea to review these items
before you start your trip. Don't forget
to also maintain your trailer and
hitch. Follow the maintenance sched-
ule that accompanied your trailer and
check it periodically. Preferably,
inspect the vehicle and trailer at the
start of each day's driving. Inspect
the hitch mounting to make sure the
hitch is properly secured to the vehi-
cle. Inspect the trailer electrical
wiring to make sure brake lights, turn
signal lights, running lights, and haz-
ard lights are working properly.
Do not get out of the vehicle
without the parking brake
firmly set. If you have left the
engine running, the vehicle
can move suddenly. You and
others could be seriously or
fatally injured.
Do not apply the accelerator
pedal to hold the vehicle on
an uphill.
WARNING

Overloading your vehicle may
cause damage. Repairs would not
be covered by your warranty. Do
not overload your vehicle.
NOTICE
If you carry items inside your
vehicle (e.g., suitcases, tools,
packages, or anything else),
they are moving as fast as the
vehicle. If you have to stop or
turn quickly, or if there is a
crash, the items will keep going
and can cause an injury if they
strike the driver or a passenger.
Put items in the cargo area of
your vehicle. Try to spread the
weight evenly.
Do not stack items, like suit-
cases, inside the vehicle
above the tops of the seats.
Do not leave an unsecured
child restraint in your vehicle.
When you carry something
inside the vehicle, secure it.

What to do in an emergency
6
If you have a tire gauge, check the
tire pressure (see "Tires and
Wheels" in chapter 8 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 stor-
age locations. If it is hard to secure
the flat tire, put the flat tire in the lug-
gage compartment.
Check the tire pressure as soon
as possible after installing a
spare tire. Adjust it to the rec-
ommended pressure.
Check and tighten the wheel lug
nuts after driving over 30 mile
(50 km) if tires are replaced.
Recheck the tire wheel lug nuts
after driving over 600 mile (1,000
km).If any of the equipment such as the
jack, lug nuts, studs, or other equip-
ment is damaged or in poor condi-
tion, do not attempt to change the
tire and call for assistance.Use of compact spare tires
Compact spare tires are designed for
emergency use only. Drive carefully
on the compact spare tire and
always follow the safety precautions.
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.
Consult an authorized HYUNDAI
dealer for assistance.
CAUTION
To prevent compact spare tire
failure and loss of control pos-
sibly resulting in an accident:
Use the compact spare tire
only in an emergency.
NEVER operate your vehicle
over 50 mph (80 km/h).
Do not exceed the vehicle's
maximum load rating or the
load carrying capacity shown
on the sidewall of the com-
pact spare tire.
Do not use the compact spare
tire continuously. Repair or
replace the original tire as
soon as possible to avoid fail-
ure of the compact spare tire.

What to do in an emergency
Emergency Towing
If towing is necessary, we recom-
mend you have it done by an author-
ized HYUNDAI dealer or a commer-
cial 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 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.
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.Always follow these emergency tow-
ing precautions:
While depressing the brake pedal
shift to the N (Neutral) position and
turn the vehicle off. The POWER
button will be in the ACC position.
Release the parking brake.
Depress the brake pedal with more
force than normal since you will
have reduced braking perform-
ance.
More steering effort will be
required because the power steer-
ing 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.
OLX2069018N
OLX2068019
The driver must be in the vehi-
cle for steering and braking
operations when the vehicle is
being towed. Passengers other
than the driver must not be in
the vehicle.

Engine Oil and Filter
The engine oil and filter should be
changed at the intervals specified in
the maintenance schedule. If the
vehicle is being driven in severe con-
ditions, more frequent oil and filter
changes are required.
Drive Belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil
saturation and replace if necessary.
Drive belts should be checked peri-
odically for proper tension and
adjusted as necessary.
Fuel Filter
A clogged-up fuel filter may limit the
vehicle driving speed, damage the
emission system, and cause the
hard starting. When a considerable
amount of foreign substances are
accumulated in the fuel tank, the fuel
filter should be replaced.
Upon installing a new fuel filter, oper-
ate the engine for several minutes,
and check the connections for any
leakages. Fuel filters should be
installed by an authorized HYUNDAI
dealer.
Fuel Lines, Fuel Hoses and
Connections
Check the fuel lines, fuel hoses and
connections for leakage and dam-
age. Have an authorized HYUNDAI
dealer replace any damaged or leak-
ing parts immediately.
Vapor Hose and Fuel Filler
Cap
The vapor hose and fuel filler cap
should be inspected at those inter-
vals specified in the maintenance
schedule. Make sure a new vapor
hose or fuel filler cap is correctly
replaced.
Vacuum Crankcase Ventilation
Hoses
Inspect the surface of hoses for evi-
dence of heat and/or mechanical
damage. Hard and brittle rubber,
cracking, tears, cuts, abrasions, and
excessive swelling indicate deterio-
ration. Particular attention should be
paid to examine those hose surfaces
nearest to high heat sources, such
as the exhaust manifold.
Inspect the hose routing to ensure
that the hoses do not come in con-
tact with any heat source, sharp
edges or moving component which
might cause heat damage or
mechanical wear. Inspect all hose
connections, such as clamps and
couplings, to make sure they are
secure, and that no leaks are pres-
ent. Hoses should be replaced
immediately if there is any evidence
of deterioration or damage.

When you do not use the vehicle
for a long time in a low tempera-
ture area, disconnect the battery
and keep it indoors.
Always charge the battery fully
to prevent battery case damage
in low temperature areas.
For Best Battery Service
Keep the battery securely mount-
ed.
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 acid from the bat-
tery immediately with a solution of
water and baking soda.
