Tongue load
Gross Axle WeightGross Vehicle Weight
OOSH069130L
The tongue load is an important weight
to measure because it affects the
total Gross Vehicle Weight (GVW) of
your vehicle. The trailer tongue should
weigh a maximum of 10% of the total
loaded trailer weight, within the limits
of the maximum trailer tongue load
permissible.
After you’ve loaded your trailer,
weigh the trailer and then the tongue,
separately, to see if the weights are
proper. If they aren’t, you may be able
to correct them simply by moving some
items around in the trailer.
WARNING
Take the following precautions:
• Never load a trailer with more weight
in the rear than in the front. The front
should be loaded with approximately
60% of the total trailer load; the rear
should be loaded with approximately
40% of the total trailer load.
• Never exceed the maximum weight
limits of the trailer or trailer towing
equipment. Improper loading can
result in damage to your vehicle and/
or personal injury. Check weights
and loading at a commercial scale or
highway patrol office equipped with
scales.
Information
With increasing altitude the engine
performance decreases. From 1,000 m
above sea level and for every 1,000 m
thereafter 10% of vehicle/trailer weight
(trailer weighter + gross vehicle weight)
must be deducted.

Backing up
Hold the bottom of the steering wheel
with one hand. Then, to move the trailer
to the left, move your hand to the left. To
move the trailer to the right, move your
hand to the right. Always back up slowly
and, if possible, have someone guide
you.
Making turns
When you’re turning with a trailer, make
wider turns than normal. Do this so your
trailer won’t strike soft shoulders, curbs,
road signs, trees, or other objects. Avoid
jerky or sudden maneuvers. Signal well in
advance.
Turn signals
When you tow a trailer, your vehicle has
to have a different turn signal flasher and
extra wiring. The green arrows on your
instrument panel will flash whenever you
signal a turn or lane change. Properly
connected, the trailer lights will also flash
to alert other drivers you’re about to turn,
change lanes, or stop.
When towing a trailer, the green arrows
on your instrument panel will flash for
turns even if the bulbs on the trailer
are burned out. Thus, you may think
drivers behind you are seeing your
signals when, in fact, they are not. It’s
important to check occasionally to be
sure the trailer bulbs are still working.
You must also check the lights every time
you disconnect and then reconnect the
wires.
WARNING
Do not connect a trailer lighting system
directly to your vehicle’s lighting
system. Use an approved trailer wiring
harness. Failure to do so could result in
damage to the vehicle electrical system
and/or personal injury. We recommend
that you consult an authorized
HYUNDAI dealer for assistance.
Driving on hills
Reduce speed and shift to a lower gear
before you start down a long or steep
downgrade. If you don’t shift down, you
might have to use your brakes so much
that they would get overheated and may
not operate efficiently.
On a long uphill grade, shift down and
reduce your speed to around 45 mph (70
km/h) to reduce the possibility of engine
and transmission overheating.
If your trailer weighs more than the
maximum trailer weight without trailer
brakes and you have a automatic
transmission, you should drive in D
(Drive) when towing a trailer.
Operating your vehicle in D (Drive)
when towing a trailer will minimize heat
build-up and extend the life of your
transmission.

Driving the vehicle after it has been
parked on a hill
1. With the gear in P (Park), apply your
brakes and hold the brake pedal down
while you:• Start your engine;
• Shift into gear; and
• Release the parking brake.
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 towing a
trailer
Your vehicle will need service more
often when you regularly pull a trailer.
Important items to pay particular
attention to include engine oil,
transmission fluid, axle lubricant 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 schedule that
accompanied your trailer and check it
periodically. Preferably, conduct the
check at the start of each day’s driving.
Most importantly, all hitch nuts and bolts
should be tight.
NOTICE
To prevent vehicle damage:
• Due to higher load during trailer
usage, overheating might occur on
hot days or during uphill driving.
If the coolant gauge indicates
over-heating, switch off the air
conditioner and stop the vehicle in a
safe area to cool down the engine.
• Do not switch off the engine while
the coolant gauge indicates over-
heating.
(Keep the engine idle to cool down
the engine)
• When towing check transmission
fluid more frequently.
• If your vehicle is not equipped with
an air conditioner, you should install
a condenser fan to improve engine
performance when towing a trailer.
