Driving your vehicle
If you decide to pull a trailer?
Here are some important points if you
decide to pull a trailer:

[Consider using a sway control. You
can ask a trailer towbar dealer about
sway control.

[Do not do any towing with your
vehicle during its first 1,200 miles
(2,000 km) in order to allow the
engine to properly break in. Failure to
heed this caution may result in serious
engine or transmission damages.

[When towing a trailer, be sure to
consult a HYUNDAI authorised repairer
for further information on additional
requirements such as a towing kit, etc.

[Always drive your vehicle at a
moderate speed (less than 60 mph
(100 km/h)) or posted towing speed
limit.

[On a long uphill grade, do not exceed
45 mph (70 km/h) or the posted
towing speed limit, whichever is lower.

[Carefully observe the weight and load
limits provided in the following pages.
Trailer weight
OLMB053047
Tongue LoadTotal Trailer Weight
What is the maximum safe weight of a
trailer? It should never weigh more than
the maximum trailer weight with trailer
brakes. But even that can be too heavy.
It depends on how you plan to use your
trailer. For example, speed, altitude,
road grades, outside temperature and
how often your vehicle is used to pull
a trailer are all important. The ideal
trailer weight can also depend on any
special equipment that you have on your
vehicle.

6-67
06
Tongue load
OLMB053048
Gross Axle WeightGross Vehicle Weight
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.

Trailer towing equipment
Towbars
OBC3060011
It's important to have the correct
towbar equipment. Crosswinds, large
trucks going by, and rough roads are a
few reasons why you’ll need the right
towbar. Here are some rules to follow:

[Do you have to make any holes in the
body of your vehicle when you install
a trailer towbar? If you do, then be
sure to seal the holes later when you
remove the towbar. If you don’t seal
them, carbon monoxide (CO) from
your exhaust can get into your vehicle,
as well as dirt and water.

[The bumpers on your vehicle are not
intended for towbars. Do not attach
rental towbars or other bumper-type
towbars to them. Use only a frame-
mounted towbar that does not attach
to the bumper.

[A HYUNDAI trailer towbar accessory
is available at a HYUNDAI authorised
repairer.
Safety chains
You should always attach chains
between your vehicle and your trailer.
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 towbar. Instructions
about safety chains may be provided
by the towbar manufacturer 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
braking system, make sure it conforms
your country’s regulations and that
it is properly installed and operating
correctly.
If your trailer weighs more than the
maximum trailer weight without trailer
brakes loaded, then it needs its own
brakes and they must be adequate. Be
sure to read and follow the instructions
for the trailer brakes so you’ll be able
to install, adjust and maintain them
properly. Be sure not to tap into your
vehicle's brake system.
WARNING
Do not use a trailer with its own brakes
unless you are absolutely certain that
you have properly set up the brake
system. This is not a task for amateurs.
Use an experienced, competent trailer
shop for this work.

6-70
Driving your vehicle
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 yourself 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 towbar
and platform, safety chains, electrical
connector(s), lights, tyres 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.
Distance
Stay at least twice as far behind the
vehicle ahead as you would when driving
your vehicle without a trailer. This can
help you avoid situations that require
heavy braking and sudden turns.
Passing
You will need more passing distance up
ahead when you’re towing a trailer. And,
because of the increased vehicle length,
you’ll need to go much farther beyond
the passed vehicle before you can return
to your lane.
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, kerbs,
road signs, trees, or other objects. Avoid
jerky or sudden manoeuvres. 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 have the
system checked by a HYUNDAI
authorised repairer as soon as possible.

6-71
06
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 an automatic
transmission/dual clutch transmission,
you should drive in D (Drive) when
towing a trailer. Operating your vehicle
in D (Drive) when towing a trailer will
minimise heat build-up and extend the
life of your transmission.
NOTICE
To prevent engine and/or transmission
overheating:

V When towing a trailer on steep
grades (in excess of 6%) pay close
attention to the engine coolant
temperature gauge to ensure the
engine does not overheat. If the
needle of the coolant temperature
gauge moves towards “H” (HOT),
pull over and stop as soon as it is
safe to do so, and allow the engine
to idle until it cools down. You may
proceed once the engine has cooled
sufficiently.

V You must decide your vehicle speed
according to the trailer weight and
uphill grade.
Parking on hills
Generally, if you have a trailer attached
to your vehicle, you should not park your
vehicle on a hill.
However, if you ever have to park your
trailer on a hill, here's how to do it:
1. Pull the vehicle into the parking space.
Turn the steering wheel in the
direction of the kerb (left if headed
down hill, right if headed up hill).
2. Shift the vehicle to P (Park, for
Automatic transmission/Dual clutch
transmission vehicle) or neutral (for
Manual transmission vehicle).
3. Set the parking brake and shut off the
vehicle.
4. Place wheel chocks under the trailer
wheels on the down hill side of the
wheels.
5. Start the vehicle, hold the brakes, shift
to neutral, release the parking brake
and slowly release the brakes until the
trailer chocks absorb the load.
6. Reapply the brakes and parking
brakes.
7. Move the shift lever to P (Park, for
Automatic transmission/Dual clutch
transmission vehicle) or the 1st gear
when the vehicle is parked on a uphill
grade and in R (Reverse) on a downhill
(for Manual transmission vehicle).
8. Shut off the vehicle and release the
vehicle brakes but leave the parking
brake set.
WARNING
To prevent serious or fatal injury:
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.

6-72
Driving your vehicle
Ready to leave after parking on a
hill
1. With the shift lever to P (Park, for
Automatic transmission/Dual clutch
transmission vehicle) or neutral (for
Manual transmission vehicle), apply
your brakes and hold the brake pedal
down whilst you:

V Start your engine;

V Shift into gear; and

V 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,
automatic transmission/dual clutch
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 towbar.
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 towbar nuts and
bolts should be tight.
NOTICE
To prevent vehicle damage:

V 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.

V When towing check Automatic
transmission/Dual clutch
transmission fluid more frequently.

V If your vehicle is not equipped with
an air conditioner, you should install
a condenser fan to improve engine
performance when towing a trailer.
