Highway driving
Tires:
Adjust the tire inflation pressures to
specification. Low tire inflation pres-
sures will result in overheating and
possible failure of the tires.
Avoid using worn or damaged tires
which may result in reduced traction
or tire failure.
Never exceed the maximum tire
inflation pressure shown on thetires.
Fuel, engine coolant and engineoil:
High speed travel consumes more
fuel than urban motoring. Do not for-
get to check both engine coolant andengine oil.
Drive belt:
A loose or damaged drive belt may
result in overheating of the engine.
NOTICE
Underinflated or overinflated tires can cause poor handling,
loss of vehicle control, and
sudden tire failure leading to
accidents, injuries, and even
death. Always check the tires
for proper inflation before
driving. For proper tire pres-
sures, refer to section 8,“Tires and wheels”.
Driving on tires with no or
insufficient tread is danger-
ous. Worn-out tires can result
in loss of vehicle control, col-
lisions, 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 vehi-
cle. For further information
and tread limits, refer to sec-
tion 7, “Tires and wheels”.

Turn signals when towing atrailer
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 dis-connect and then reconnect the
wires.
The ECU of the tow bar wiring har-
ness warns the driver about the
burned-out bulbs on the trailer by
flashing the green arrows on the
instrument panel with the warningsound. Do not connect a trailer lighting sys-
tem directly to your vehicle’s lighting
system. Use only an approved trailer
wiring harness.
An authorized HYUNDAI dealer can
assist you in installing the wiring har-
ness.
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 70km/h (45 mph) to reduce the possi-
bility of engine and transmission
overheating.
If your trailer weighs more than the
maximum trailer weight without trail-
er brakes.
Failure to use an approved trail-er wiring harness could result
in damage to the vehicle electri-
cal system and/or personal
injury.

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 unexpectedly roll
down hill.However, if you ever have to park
your trailer on a hill, here's how to doit:
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 uphill).
2. If the vehicle has a manual trans- mission, place the vehicle in neu-
tral.
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.
5. Start the vehicle, hold the brakes, shift to neutral, release the parking
brake and slowly release the
brakes until the trailer chocksabsorb the load.
6. Reapply the brakes, reapply the parking brake and shift the vehicle
to R (Reverse) for manual trans-mission.
7. Shut off the vehicle and release the vehicle brakes but leave the
parking brake set.
When towing a trailer on steep
grades (in excess of 6%) pay
close attention to the engine
coolant temperature gauge toensure the engine does not
overheat. 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 proceedonce the engine has cooled
sufficiently.
You must decide driving speed depending on trailerweight and uphill grade toreduce the possibility ofengine and transmission
overheating.
CAUTION
Parking on a hill
Parking your vehicle on a hill
with a trailer attached could
cause serious injury or death,
should the trailer break loose.

If you do decide to pull a trail- er
Here are some important points if
you decide to pull a trailer:
Consider using a sway control. Youcan ask a hitch dealer about sway control.
Do not do any towing with your vehicle during 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 transmission
damage.
When towing a trailer, we recom- mend that you consult an author-
ized HYUNDAI dealer on addition-
al requirements such as a towingkit, etc.
Always drive your vehicle at a mod- erate speed (Max speed for stan-
dard trailer is 80 km/h (50 mph)). ❇ Special trailer 100 km/h (60
mph) is allowed but trailer need
special approval from TÜV. On a long uphill grade, do not
exceed 70 km/h (45 mph) or the
posted towing speed limit,
whichever is lower.
Fuel consumption will increase due to the additional required power to
tow trailer and additional trans-
portation weight at the trailer.
To prevent vehicle damage :
Due to higher load during
trailer usage, overheating
might occur in hot days or
during uphill driving. 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 transmis-
sion fluid more frequently.
If your vehicle is not equipped
with the air conditioner, youshould install a condenser fan
to improve engine perform-
ance when towing a trailer.

What to do in an emergency
5.Start the engine of the vehicle withthe booster battery and let it run at
2,000 rpm, then start the engine of
the vehicle with the discharged
battery.
If the cause of your battery discharg-
ing is not apparent, we recommendthat the system be checked by an authorized HYUNDAI dealer.
Push-starting
Your manual transmission-equipped
vehicle should not be push-startedbecause it might damage the emis-sion control system. If your temperature gauge indicates
overheating, you experience a loss
of power, or hear loud pinging 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 neutral and set the parking brake. If the air con-
ditioning is on, turn it off.
3.If engine coolant is running out under the vehicle or steam is com-ing 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 oper-
ating. If the fan is not running, turn
the engine off.

Never tow a vehicle to start it
because the sudden surge for-
ward when the engine startscould cause a collision with the
tow vehicle.

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 leak-
ing from the radiator, hoses or
under the vehicle. (If the air condi-
tioning had been in use, it is nor-
mal for cold water to be draining
from it when you stop). 5.If the water pump drive belt is bro-
ken or engine coolant is leakingout, stop the engine immediately
and we recommend that you call
an authorized HYUNDAI dealer. 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
authorized HYUNDAI dealer.
What to do in an emergency
While the engine is running,
keep hair, hands and clothing
away from moving parts suchas the fan and drive belts to pre-
vent injury.
WARNING
Do not remove the radiator cap
when the engine is hot. This can
allow coolant to be blown out ofthe opening and cause serious
burns.
WARNING
Serious loss of coolant indi- cates there is a leak in thecooling system and we rec-ommend that the system be
checked by an authorized
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 insmall quantities.
CAUTION

7-24
Maintenance
The high-pressure cooling system
has a reservoir filled with year-round
antifreeze coolant. The reservoir is
filled at the factory. Check the
antifreeze protection and coolant
level at least once a year, at thebeginning of the winter season, and
before traveling to a colder climate.Checking the coolant level
EENN GGIINN EE CC OO OOLLAA NN TT

Do not drive with no engine
coolant. It may cause waterpump failure and engine
seizure, etc.
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 insmall quantities.
CAUTION
Removing radiator
cap
Never attempt to remove the radiator cap while the engine
is operating or hot. Doing somight lead to cooling system
and engine damage and could
result in serious personal
injury from escaping hotcoolant 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 fromthe cooling system.
(Continued)
WARNING (Continued)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.
Even if the engine is not oper-
ating, do not remove the radi-ator cap or the drain plugwhile the engine and radiator
are hot. Hot coolant and
steam may still blow out
under pressure, causing seri-
ous injury.
