If you are considering to tow with
your vehicle, you should first check
your country's legal requirements.
Since laws vary, the requirements for
towing trailers, cars, or other types of
vehicles or apparatus may differ. Ask
an authorised HYUNDAI dealer for
further details before towing.
Remember that towing is different
than just driving your vehicle by itself.
Towing means changes in handling,
durability, and fuel economy.
Successful, safe trailering requires
correct equipment, and it has to be
used properly. Damage to your vehi-
cle caused by improper trailer towing
is not covered by your vehicle manu-
facturer’s warranty.
This section contains many time-
tested, important trailering tips and
safety rules. Many of these are
important for your safety and that of
your passengers. Please read this
section carefully before you pull a
trailer.If you decide to pull a trailer?
Here are some important points if
you decide to pull a trailer:
• Do not do any towing with your
vehicle during its first 2,000 km 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
consult an authorised HYUNDAI
dealer for further information on
additional requirements such as a
towing kit, etc.
• Always drive your vehicle at a mod-
erate speed (less than 100 km/h)
or posted towing speed limit.
• On a long uphill grade, do not
exceed 70 km/h or the posted tow-
ing speed limit, whichever is lower.
TRAILER TOWING
WARNING
Take the following precautions:
• If you don't use the correct
equipment and/or drive
improperly, you can lose con-
trol of the vehicle when you
are pulling a trailer. For exam-
ple, if the trailer is too heavy,
the braking performance may
be reduced. You and your pas-
sengers could be seriously or
fatally injured. Pull a trailer
only if you have followed all
the steps in this section.
• Before towing, make sure the
total trailer weight, GCW
(Gross Combination Weight),
GVW (Gross Vehicle Weight),
GAW (Gross Axle Weight ) and
trailer tongue load are all with-
in the limits.

6.Reapply the brakes and parking
brakes.
7.Move the shift lever to P (Park, for
automatic transaxle vehicle) or 1st
gear when the vehicle is parked on
a uphill grade and in R (Reverse)
on a downhill (for manual transaxle
vehicle).
8.Turn off the vehicle and release the
vehicle brakes but leave the park-
ing brake set.Ready to leave after parking on a
hill
1.With the shift lever to P (Park, for
automatic transaxle vehicle) or
neutral (for manual transaxle vehi-
cle), apply your brakes and hold
the brake pedal down whilst 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 trail-
er. Important items to pay particular
attention to include engine oil, auto-
matic transaxle fluid, axle lubricant
and cooling system fluid. Brake con-
dition 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 tow-
bar. Follow the maintenance sched-
ule 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 nuts and bolts should be
tight.
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.

Driving your vehicle
CAUTION
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 con-
ditioner and stop the vehicle
in a safe area to cool down the
engine.
• When towing check automatic
transaxle fluid more frequently.

IF THE ENGINE WILL NOT START
If the engine doesn't turn over
or turns over slowly
• Be sure the shift lever is in N
(Neutral) or P (Park) if it is an auto-
matic transaxle vehicle. The engine
starts only when the shift lever is in
N (Neutral) or P (Park).
• Check the battery connections to
be sure they are clean and tight.
• Turn on the interior light. If the light
dims or goes out when you operate
the ignition, the battery is drained.
Do not push or pull the vehicle to
start it. This could cause damage to
your vehicle. See instructions for
"Jump Starting" provided in this
chapter.
If the engine turns over nor-
mally but doesn’t start
• Check the fuel level and add fuel if
necessary.
If the engine still does not start, we
recommend that you call an autho-
rised HYUNDAI dealer for assis-
tance.

Push or pull starting the vehicle
may cause the catalytic con-
verter to overload which can
lead to damage to the emission
control system.

4.Connect the jumper cables in the
exact sequence shown in the illus-
tration. First connect one jumper
cable to the red, positive (+)
jumper terminal of your vehicle (1).
5.Connect the other end of the
jumper cable to the red, positive
(+) battery/jumper terminal of the
assisting vehicle (2).
6.Connect the second jumper cable
to the black, negative (-)
battery/chassis ground of the
assisting vehicle (3).7.Connect the other end of the sec-
ond jumper cable to the black, neg-
ative (-) chassis ground of your
vehicle (4).
Do not allow the jumper cables to
contact anything except the correct
battery or jumper terminals or the
correct ground. Do not lean over
the battery when making connec-
tions.
8.Start the engine of the assisting
vehicle and let it run at approxi-
mately 2,000 rpm for a few min-
utes. Then start your vehicle.
If your vehicle will not start after a
few attempts, it probably requires
servicing. In this event please seek
qualified assistance. If the cause of
your battery discharging is not
apparent, we recommend that your
vehicle be checked by an authorised
HYUNDAI dealer.Disconnect the jumper cables in the
exact reverse order you connected
them:
1.Disconnect the jumper cable from
the black, negative (-) chassis
ground of your vehicle (4).
2.Disconnect the other end of the
jumper cable from the black, nega-
tive (-) battery/chassis ground of
the assisting vehicle (3).

If your temperature gauge indicates
overheating, you experience a loss
of power, or hear loud pinging or
knocking, the engine may be over-
heating. If this happens, you should:
1.Pull off the road and stop as soon
as it is safe to do so.
2.Place the shift lever in P (Park, for
automatic transaxle vehicle) or
neutral (for manual transaxle vehi-
cle) and set the parking brake. If
the air conditioning is ON, turn it
OFF.
3.If engine coolant is running out
under the vehicle or steam is com-
ing out from the bonnet, stop the
engine. Do not open the bonnet
until the coolant has stopped run-
ning or the steaming has stopped.
If there is no visible loss of engine
coolant and no steam, leave the
engine running and check to be
sure the engine cooling fan is oper-
ating. If the fan is not running, turn
the engine off.4.Check for coolant leaking from the
radiator, hoses or under the vehi-
cle. (If the air conditioning had
been in use, it is normal for cold
water to be draining from it when
you stop.)
5.If engine coolant is leaking out,
stop the engine immediately and
we recommend that you call an
authorised HYUNDAI dealer for
assistance.
IF THE ENGINE OVERHEATS
What to do in an emergency
8 6
WARNING
Whilst the engine is
running, keep hands,
clothing and tools
away from the moving
parts such as the
cooling fan and drive
belt to prevent seri-
ous injury.
WARNING
NEVER remove the
radiator cap or the
drain plug whilst the
engine and radiator
are hot. Hot coolant
and steam may blow out under
pressure, causing serious
injury.
Turn the engine off and wait
until the engine cools down.
Use extreme care when remov-
ing the radiator cap. Wrap a
thick towel around it, and turn it
anticlockwise slowly to the first
stop. Step back whilst the pres-
sure is released from the cool-
ing system. When you are sure
all the pressure has been
released, press down on the
cap, using a thick towel, and
continue turning anticlockwise
to remove it.

6.If you cannot find the cause of the
overheating, wait until the engine
temperature has returned to nor-
mal. Then, if coolant has been lost,
carefully add coolant to the reser-
voir to bring the fluid level in the
reservoir up to the halfway mark.
7.Proceed with caution, keeping
alert for further signs of overheat-
ing. If overheating happens again,
we recommend that you call an
authorised HYUNDAI dealer for
assistance.

What to do in an emergency
CAUTION
• Serious loss of coolant indi-
cates a leak in the cooling
system and we recommend
the system be checked by an
authorised HYUNDAI dealer.
• When the engine overheats
from low engine coolant, sud-
denly adding engine coolant
may cause cracks in the
engine. To prevent damage,
add engine coolant slowly in
small quantities.
