E140400AUN-EA 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 a good deal longer and not
nearly so responsive as your vehicle is
by itself.
Before you start, check the trailer towbar
and platform, safety chains, electrical
connector(s), lights, tyres and mirror
adjustment. If the trailer has electric
brakes, start your vehicle and trailer mov-
ing and then apply the trailer brake con-
troller by hand to be sure the brakes are
working. This lets you check your electri-
cal connection at the same time.
During your trip, check occasionally to be
sure that the load is secure, and that the
lights and any trailer brakes are still work-ing.
E140401AUN
Following distance
Stay at least twice as far behind the vehi-
cle ahead as you would when driving
your vehicle without a trailer. This can
help you avoid situations that require
heavy braking and sudden turns. E140402AUN-EA
Passing
You’ll need more passing distance up
ahead when you’re towing a trailer. Due
to the increased vehicle length, you’ll
need to go much farther beyond the
passed vehicle before you can return to
your lane.
E140403AUN
Backing up
Hold the bottom of the steering wheel
with one hand. Then, to move the trailer
to the left, just 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.
E140404AUN-EA
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.
E140405AFD-EA
Turn signals when towing a trailer
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 trail-
er bulbs are still working. You must also
check the lights every time you discon-
nect and then reconnect the wires.
Do not connect a trailer lighting system
directly to your vehicle’s lighting system.
Use only an approved trailer wiring har-
ness.
An authorised HYUNDAI dealer can
assist you in installing the wiring harness.
WARNING
Failure to use an approved trailer wiring harness could result in dam-
age to the vehicle electrical system
and/or personal injury.

Driving on grades
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 hot and no longer
operate efficiently.
On a long uphill grade, shift down and
reduce your speed to around 70 km/h (45mph) to reduce the possibility of engine
and transaxle overheating.
If your trailer weighs more than the max-
imum trailer weight without trailer brakes
and you have an automatic transaxle,
you should drive in D (Drive) when tow-
ing a trailer.
Operating your vehicle in D (Drive) when
towing a trailer will minimise heat build up
and extend the life of your transaxle.E140407AUN-EA
Parking on hills
Generally, you should not park your vehi-
cle, with a trailer attached, on a hill.
People can be seriously injured or cause
fatality, and both your vehicle and the
trailer can be damaged if they begin a
downhill trajectory.
However, if you ever have to park your
trailer on a hill, here’s how to do it:
1. Apply your brakes, but don’t shift into
gear.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the brakes until the chocks absorb the load.
4. Reapply the brakes. Apply your park- ing brake, and then shift to R
(Reverse) for a manual transaxle or P
(Park) for an automatic transaxle.
5. Release the brakes.
CAUTION
When towing a trailer on steep grades (in excess of 6%) payclose attention to the enginecoolant temperature gauge to
ensure the engine does not over- heat.
If the needle of the coolant tem-perature gauge moves across thedial towards “H” (HOT), pull over
and stop as soon as it is safe to do so, and allow the engine to idleuntil it cools down. You may pro-
ceed once the engine has cooledsufficiently.
You must decide driving speed depending on trailer weight anduphill grade to reduce the possi-
bility of engine and transaxle overheating.
WARNING - Parking on a
hill
Parking your vehicle on a hill with a
trailer attached could cause seri-
ous injury or death, should the trail-
er break lose.

When you are ready to leave after park- ing on a hill
1. With the manual transaxle in Neutral
or automatic transaxle in P (Park),
apply your brakes and hold the brake
pedal down while you:

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. E140500AUN-EA
Maintenance when trailer towing
Your vehicle will need service more often
when you regularly towing a trailer.
Important items to pay particular atten-tion to include engine oil, automatic
transaxle fluid, axle lubricant and cooling
system fluid. Brake condition is another
important item to check frequently. Each
item is covered in this manual, and the
Index will help you find them quickly. If
you’re towing, it’s a good idea to review
these sections 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, con-
duct the check at the start of each day’s
driving. Most importantly, all towbar nutsand bolts should be tight.
WARNING
- Parking brake
It can be dangerous to get out of
your vehicle if the parking brake is
not firmly set.
If you have left the engine running,
the vehicle can move suddenly. You
or others can be seriously injured
or cause fatality.CAUTION
Due to higher load during trailer usage, overheating might occurin hot days or during uphill driv- ing. If the coolant gauge indicates
over-heating, switch off the A/C and stop the vehicle in a safe areato cool down the engine.
When towing check transaxle fluid more frequently.
If your vehicle is not equipped with the air conditioner, youshould install a condenser fan to improve engine performance
when towing a trailer.

If you do decide to pull a trailer
Here are some important points if you
decide to pull a trailer:
Consider using a sway control. You canask a towbar dealer about sway con- trol.
Do not do any towing with your car dur- ing its first 2,000 km (1,200 miles) in
order to allow the engine to properly
break in. Failure to heed this caution
may result in serious engine or
transaxle damage.
When towing a trailer, be sure to con- sult an authorised HYUNDAI dealer for
further information on additional
requirements such as a towing kit, etc.
Always drive your vehicle at a moder- ate speed (less than 100 km/h (60mph)).
On a long uphill grade, do not exceed 70 km/h (45 mph) or the posted towing
speed limit, whichever is lower.

Weight of the trailer
How heavy can a trailer safely be? It
should never weigh more than the maxi-
mum 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 equip-
ment that you have on your vehicle. E140602AEN-EA
Weight of the trailer tongue
The tongue load of any trailer is an
important weight to measure because it
affects the total gross vehicle weight
(GVW) of your vehicle. This weight
includes the kerb weight of the vehicle,
any cargo you may carry in it, and the
people who will be riding in the vehicle.
And if you will tow a trailer, you must addthe tongue load to the GVW because
your vehicle will also be carrying that
weight.
The trailer tongue should weigh 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.
Tongue loads can be increased or
decreased by redistributing the load in
the trailer. This can be verified by check-
ing the total weight of the loaded trailer
and then checking the load on the
tongue.
WARNING -
Trailer
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 approximately40% of the total trailer load.

Hazard warning flasher
The hazard warning flasher serves as a
warning to other drivers to exercise
extreme caution when approaching,
overtaking, or passing your vehicle. It should be used whenever emergency
repairs are being made or when the vehi-cle is stopped near the edge of a road-
way.
Depress the flasher switch with the igni-
tion switch in any position. The flasher
switch is located in the centre console
switch panel. All turn signal lights will
flash simultaneously.
• The hazard warning flasher operates
whether your vehicle is running or not.
The turn signals do not work when the hazard flasher is on.
Care must be taken when using the hazard warning flasher while the vehi-
cle is being towed. F020100AUN
If the engine stalls at a crossroad
or crossing
If the engine stalls at a crossroad or
crossing, set the shift lever in the N
(Neutral) position and then push the
vehicle to a safe place.
If your vehicle has a manual transaxle not equipped with a ignition lock
switch, the vehicle can move forward
by shifting to the 2(second) or 3(third)
gear and then turning the starter with-out depressing the clutch pedal.

If you have a flat tyre while driv- ing
If a tyre goes flat while you are driving:
1. Take your foot off the accelerator pedal and let the car slow down while driving
straight ahead. Do not apply the brakesimmediately or attempt to pull off the
road as this may cause a loss of con-
trol. When the car has slowed to such
a speed that it is safe to do so, brake
carefully and pull off the road. Drive off
the road as far as possible and park on
firm, level ground. If you are on a divid-
ed highway, do not park in the median
area between the two traffic lanes.IN CASE OF AN EMERGENCY WHILE DRIVING
