If you are considering towing with your
vehicle, you should first check with your
local road authorities to determine their
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.Your vehicle can tow a trailer. To identify
what the vehicle trailering capacity is for
your vehicle, you should read the infor-
mation in “Weight of the trailer” that
appears later in this section.
When towing it is different than just driv-
ing your vehicle by itself. Towing means
changes in handling, durability, and fuel
economy. Successful, safe towing
requires correct equipment, and it has to
be used properly.
This section contains many time-tested,
important towing 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.
Load-pulling components such as the
engine, transaxle, wheel assemblies, and
tyres are forced to work harder against
the load of the added weight. The engine
is required to operate at relatively higher
speeds and under greater loads. This
additional burden generates extra heat.
The trailer also adds considerable wind
resistance, increasing pulling require-
ments.
TRAILER TOWING
WARNING- Towing a trailer
If you don't use the correct equip-
ment and drive improperly, you can
lose control when you pull a trailer.
For example, if the trailer is too
heavy, the brakes may not work
well - or even at all. You and your
passengers could be seriously or
fatally injured. Pull a trailer only if
you have followed all the steps in
this section.
WARNING- Weight limits
Before towing, make sure the total
trailer weight, gross combination
weight, gross vehicle weight, gross
axle weight and trailer tongue load
are all within the limits.
CAUTION
Pulling a trailer improperly can
damage your vehicle and result in
costly repairs not covered by your
warranty. To pull a trailer correctly,
follow the advice in this section.

Driving your vehicle
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 genuine wiring
harness.
Driving on grades
Reduce speed and shift to a lower gear
before you start down a long or steep
downgrade. If you do not down shift, you
may have to use extended braking, cre-
ating heat and potentially reducing brak-
ing efficiency.
On a long uphill grade, shift to a lower
gear and reduce your speed to around
70 km/h (45 mph) to reduce the possibil-
ity of to engine and transaxle overheat-
ing.WARNING
Failure to use an approved trailer
wiring harness could result in dam-
age to the vehicle electrical system
and/or personal injury.
CAUTION
• 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 over-
heat. If the needle of the coolant
temperature gauge moves across
the dial 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.
• You must decide driving speed
depending on trailer weight and
uphill grade to reduce the possi-
bility of engine and transaxle
overheating.

569
Driving your vehicle
When you are ready to leave after park-
ing on a hill
1. With the manual transaxle in Neutral
or automatic transaxle/Continuously
Variable Transaxle/Dual clutch trans-
mission in P (Park), 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 trailer.
Important items to pay particular atten-
tion to include engine oil, transaxle fluid,
axle lubricant and cooling system fluid.
Brake condition is another important item
to frequently check.
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 nuts
and bolts should be tight.CAUTION
• Due to higher load during trailer
usage, overheating might occur
on hot days or during uphill driv-
ing. 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.
• When towing, check the transaxle
fluid more frequently.

IF THE ENGINE WILL NOT START
If engine doesn't turn over or
turns over slowly
1. If your vehicle has an automatic
transaxle/Continuously Variable
Transaxle/Dual clutch transmission, be
sure the shift lever is in N (Neutral) or
P (Park) and the emergency brake is
set.
2. Check the battery connections to be
sure they are clean and tight.
3. Turn on the interior light. If the light
dims or goes out when you operate the
starter, the battery may be discharged.
4. Check the starter connections to be
sure they are securely tightened.
5. Do not push or pull the vehicle to start
it. See instructions for "Jump starting".
If engine turns over normally but
does not start
1. Check fuel level.
2. With the ignition switch in the LOCK
/OFF position, check all connectors at
the ignition coils and spark plugs.
Reconnect any that may be discon-
nected or loose.
3. Check the fuel line in the engine com-
partment.
4. If the engine still does not start, call an
authorised HYUNDAI dealer.
WARNING
If the engine will not start, do not
push or pull the vehicle to start it.
This could result in a collision or
cause other damage. In addition,
push or pull starting may cause the
catalytic converter to be over-
loaded and create a fire hazard.

Jump starting procedure
1. Make sure the booster battery is 12-
volt and that its negative terminal is
grounded.
2. If the booster battery is in another
vehicle, do not allow the vehicles to
touch.
3. Turn off all unnecessary electrical
loads.
4. Connect the jumper cables in the exact
sequence shown in the illustration.
First connect one end of a jumper
cable to the positive terminal of the
jump start connector (1), then connect
the other end to the positive terminal
on the booster battery (2).
Proceed to connect one end of the
other jumper cable to the negative ter-
minal of the booster battery (3), then
the other end to the negative terminal
of the jump start connector (4). Do not
connect it to or near any part that
moves when the engine is cranked.Do not allow the jumper cables to con-
tact anything except the correct battery
terminals or the correct ground. Do not
lean over the battery when making
connections.
5. Start the engine of the vehicle with the
booster battery and let it run at 2,000
rpm, then start the engine of the vehi-
cle with the discharged battery.
If the cause of your battery discharging is
not apparent, you should have your vehi-
cle checked by an authorised HYUNDAI
dealer.
Push-starting
Your manual transaxle-equipped vehicle
should not be push-started because it
might damage the emission control sys-
tem.
Vehicles equipped with automatic
transaxle/Continuously Variable
Transaxle/Dual clutch transmission can-
not be push-started.
Follow the directions in this section for
jump-starting.
CAUTION- Battery cables
Do not connect the jumper cable
from the negative terminal of the
booster battery to the negative ter-
minal of the discharged battery.
This can cause the discharged bat-
tery to overheat and crack, releas-
ing battery acid.
WARNING
Never tow a vehicle to start it
because the sudden surge forward
when the engine starts could cause
a collision with the tow vehicle.

What to do in an emergency
IF THE ENGINE OVERHEATS
If your temperature gauge indicates over-
heating, you experience a loss of power
or knocking, the engine is probably too
hot. 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 (automatic
transaxle / Continuously Variable
Transaxle / Dual clutch transmission)
or neutral (manual transaxle) and set
the parking brake. If the air condition-
ing is on, turn it off.
3. If engine coolant is running out under
the car or steam is coming out from
the bonnet, stop the engine. Do not
open the bonnet until the coolant has
stopped running 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 operat-
ing. If the fan is not running, turn the
engine off.4. With the engine turned off, check to
see if the water pump drive belt is
missing. If it is not missing, check to
see that it is tight. If the drive belt
seems to be satisfactory, check for
coolant leaking from the radiator,
hoses or under the car. (If the air con-
ditioning had been in use, it is normal
for cold water to be draining from it
when you stop.)
5. If the water pump drive belt is broken
or engine coolant is leaking out, stop
the engine immediately and call the
nearest authorised HYUNDAI dealer
for assistance.6. If you cannot find the cause of the
overheating, wait until the engine tem-
perature has returned to normal. Then,
if coolant has been lost, carefully add
coolant to the reservoir to bring the
fluid level in the reservoir up to the
halfway mark.
7. Proceed with caution, keeping alert for
further signs of overheating. If over-
heating happens again, call an autho-
rised HYUNDAI dealer for assistance.
WARNING
Whilst the engine is running, keep
hair, hands and clothing away from
moving parts such as the fan and
drive belts to prevent injury.
WARNING
Do not remove the radiator cap
when the engine is hot. This can
allow coolant to be blown out of the
opening and cause serious burns.
CAUTION
• Serious loss of coolant indicates
there is a leak in the cooling sys-
tem and this should be checked
as soon as possible by an autho-
rised HYUNDAI dealer.
• When the engine overheats from
low engine coolant, suddenly
adding engine coolant may cause
cracks in the engine. To prevent
damage, add engine coolant
slowly in small quantities.

Maintenance
Engine compartment precautions
(Diesel engine)
• Follow the safety tips provided below,
when you are checking the engine bay
whilst the engine is running.
- Do not touch the injector, injector
wirings, and the engine computer
whilst the engine is running.
- Do not remove the injector connector
whilst the engine is running.
- People using pacemakers must not
go near the engine whilst the engine
is starting or running.
WARNING- Maintenance
work
• Performing maintenance work on
a vehicle can be dangerous. You
can be seriously injured whilst
performing some maintenance
procedures. If you lack sufficient
knowledge and experience or the
proper tools and equipment to do
the work, have it done by an
authorised HYUNDAI dealer.
• Working under the bonnet with
the engine running is dangerous.
It becomes even more dangerous
when you wear jewelry or loose
clothing. These can become
entangled in moving parts and
result in injury. Therefore, if you
must run the engine whilst work-
ing under the bonnet, make cer-
tain that you remove all jewelry
(especially rings, bracelets,
watches, and necklaces) and all
neckties, scarves, and similar
loose clothing before getting
near the engine or cooling fans.
WARNING- Diesel Engine
Never work on injection system
with engine running or within 30
seconds after shutting off engine.
High-pressure pump, rail, injectors
and high-pressure pipes are sub-
ject to high pressure even after the
engine stopped. The fuel jet pro-
duced by fuel leaks may cause seri-
ous injury, if it touches the body.
People using pacemakers should
not move within 30cm of the ECU or
wiring harness within the engine
room whilst engine is running, high
currents used in the electronic
engine control system produce
considerable magnetic fields.
CAUTION
• Do not put heavy objects or apply
excessive force on top of the
engine cover (if equipped) or fuel
related parts.
• When you inspect the fuel system
(fuel lines and fuel injection
devices), we recommend that you
contact an authorised HYUNDAI
dealer.
• Do not drive long time with the
engine cover (if equipped)
removed.
• When checking the engine room,
do not go near fire. Fuel, washer
fluid, etc. are flammable oils that
may cause fire.
• Before touching the battery, igni-
tion cables and electrical wiring,
you should disconnect the bat-
tery "-" terminal. You may get an
electric shock from the electric
current.
• When you remove the interior
trim cover with a flat head (-) driv-
er, be careful not to damage the
cover.
• Be careful when you replace and
clean bulbs to avoid burns or
electrical shock.

OWNER MAINTENANCE
The following lists are vehicle checks and
inspections that should be performed by
the owner or an authorised HYUNDAI
dealer at the frequencies indicated to
help ensure safe, dependable operation
of your vehicle.
Any adverse conditions should be
brought to the attention of your dealer as
soon as possible.
These Owner Maintenance Checks are
not covered by warranties and you may
be charged for labour, parts and lubri-
cants used.Owner maintenance schedule
When you stop for fuel:
• Check the engine oil level.
• Check coolant level in coolant reser-
voir.
• Check the windscreen washer fluid
level.
• Look for low or under-inflated tyres.
Whilst operating your vehicle:
• Note any changes in the sound of the
exhaust or any smell of exhaust fumes
in the vehicle.
• Check for vibrations in the steering
wheel. Notice any increased steering
effort or looseness in the steering
wheel, or change in its straight-ahead
position.
• Notice if your vehicle constantly turns
slightly or “pulls” to one side when trav-
elling on smooth, level road.
• When stopping, listen and check for
unusual sounds, pulling to one side,
increased brake pedal travel or “hard-
to-push” brake pedal.
• If any slipping or changes in the oper-
ation of your automatic transaxle/
Continuously Variable Transaxle
occurs, check the automatic transaxle/
Continuously Variable Transaxle fluid
level.
• Check manual transaxle operation,
including clutch operation.
• Check automatic transaxle/
Continuously Variable Transaxle/Dual
clutch transmission P (Park) function.
WARNING
Be careful when checking your
engine coolant level when the
engine is hot. Scalding hot coolant
and steam may blow out under
pressure. This could cause burns
or other serious injury.
