Tires
Adjust the tire inflation pressures to
specification. Low tire inflation pressures
will result in overheating and possible
failure of the tires.
Avoid using worn or damaged tires which
may result in reduced traction or tire fail-
ure.
✽NOTICE
Never exceed the maximum tire inflation
pressure shown on the tires.
Fuel, engine coolant and engine oil
High speed travel consumes more fuel
than urban motoring. Do not forget to
check both engine coolant and engine
oil.
Drive belt
A loose or damaged drive belt may result
in overheating of the engine.
WARNING
• Underinflated or overinflated
tires can cause poor handling,
loss of vehicle control, and sud-
den tire failure leading to acci-
dents, injuries, and even death.
Always check tires for proper
inflation before driving. For prop-
er tire pressures, refer to “Tires
and wheels” in section 9.
• Driving on tires with no or insuffi-
cient tread is dangerous. Worn-
out tires can result in loss of
vehicle control, collisions, injury,
and even death. Worn-out tires
should be replaced as soon as
possible and should never be
used for driving. Always check
the tire tread before driving your
car. For further information and
tread limits, refer to “Tires and
wheels” in section 7.

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 (45
mph) to reduce the possibility of engine
and transmission overheating.
If your trailer weighs more than the max-
imum trailer weight without trailer brakes
and you have an automatic transmission,
you should drive in D (Drive) when tow-
ing a trailer.
Operating your vehicle in D (Drive) when
towing a trailer will minimize heat build up
and extend the life of your transmission.

Parking on hills
Generally, if you have a trailer attached to
your vehicle, you should not park your
vehicle on a hill. People can be seriously
or fatally injured, and both your vehicle
and the trailer can be damaged if unex-
pectedly roll down 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 curb (right if headed down hill,
left if headed up hill).
2. If the vehicle has a manual transmis-
sion, place the car in neutral. If the
vehicle has an automatic transmission,
place the car in P (Park).
3. Set the parking brake and shut off the
vehicle.
4. Place chocks under the trailer wheels
on the down hill side of the wheels.
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 loose.
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.
(Continued)
(Continued)
If the needle of the coolant tem-
perature 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 pro-
ceed 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 transmission
overheating.
CAUTION
Going uphill under hot ambient
temperature (above 35°C) with GVW
and/or trailer, a minimal fuel tank
level of 5 liter has to be assured in
order to prevent power limitation
due to fuel overheating as well as
further damages in the fuel injec-
tion equipment.

Driving your vehicle
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, reapply the park-
ing brake and shift the vehicle to R
(Reverse) for manual transmission or
P (Park) automatic transmission.
7. Shut off the vehicle and release the
vehicle brakes but leave the parking
brake set.
When you are ready to leave after park-
ing on a hill
1. With the manual transmission in
Neutral or automatic transmission 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 trailer towing
Your vehicle will need service more often
when you regularly pull a trailer.
Important items to pay particular atten-
tion to include engine oil, automatic
transmission fluid, axle lubricant and
cooling system fluid. Brake condition is
another important item to frequently
check. Each item is covered in this man-
ual, and the Index will help you find them
quickly. If you’re trailering, it’s a good idea
to review these sections 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, con-
duct the check at the start of each day’s
driving. Most importantly, all hitch nuts
and 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 could be seriously or
fatally injured.
CAUTION
• Due to higher load during trailer
usage, overheating might occur
in 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 area
to cool down the engine.
• When towing check transmission
fluid more frequently.
• If your vehicle is not equipped
with the air conditioner, you
should install a condenser fan to
improve engine performance
when towing a trailer.

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
discharged battery (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 a solid, stationary,
metallic point (for example, the engine
lifting bracket) away from the battery
(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, we recommend that the
system be checked by an authorized
HYUNDAI dealer.

Push-starting
Your manual transmission-equipped
vehicle should not be push-started
because it might damage the emission
control system.
Vehicles equipped with automatic trans-
mission cannot 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.

IF THE ENGINE OVERHEATS
F050000BFD
If your temperature gauge indicates over-
heating, you experience a loss of power,
or hear loud pinging or knocking, the
engine is probably too hot. If this hap-
pens, you should:
1. Pull off the road and stop as soon as it
is safe to do so.
2. Place the gear selector lever in P
(automatic transmission) or neutral
(manual transmission) and set the
parking brake. If the air conditioning is
on, turn it off.
3. If engine coolant is running out under
the car or steam is coming out from
the hood, stop the engine. Do not open
the hood 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 operating. If
the fan is not running, turn the engine
off.4. 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 we recom-
mend that you call an authorized
HYUNDAI dealer.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, we recom-
mend that you call an authorized
HYUNDAI dealer.
CAUTION
• Serious loss of coolant indicates
there is a leak in the cooling sys-
tem and we recommend that the
system be checked by an author-
ized 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.
WARNING
While 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.

The high-pressure cooling system has a
reservoir filled with year-round antifreeze
coolant. The reservoir is filled at the fac-
tory. Check the antifreeze protection and
coolant level at least once a year, at the
beginning of the winter season, and
before traveling to a colder climate.

Checking the coolant level
WARNING
Used engine oil may cause irrita-
tion or cancer of the skin if left in
contact with the skin for prolonged
periods of time. Used engine oil
contains chemicals that have
caused cancer in laboratory ani-
mals. Always protect your skin by
washing your hands thoroughly
with soap and warm water as soon
as possible after handling used oil.
ENGINE COOLANT
WARNING
Removing radiator
cap
• Never attempt to remove the radi-
ator cap while the engine is oper-
ating or hot. Doing so might lead
to cooling system and engine
damage and could result in seri-
ous personal injury from escap-
ing hot coolant or steam.
• Turn the engine off and wait until
it cools down. Use extreme care
when removing the radiator cap.
Wrap a thick towel around it, and
turn it counterclockwise slowly to
the first stop. Step back while the
pressure is released from the
cooling system. When you are
sure all the pressure has been
released, press down on the cap,
using a thick towel, and continue
turning counterclockwise to
remove it.
(Continued)CAUTION
• Do not drive with no engine
coolant. It may cause water pump
failure and engine seizure, etc.
• 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.
