Driving your vehicle6-88
Driving the vehicle after it has been
parked on a hill
1. With the gear 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 towing a
trailer
Your vehicle will need service more
often when you regularly pull a trailer.
Important items to pay particular
attention to include engine oil,
transmission fluid, axle lubricant and
cooling system fluid. Brake condition
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 hitch.
Follow the maintenance schedule that
accompanied your trailer and check it
periodically. Preferably, conduct the
check at the start of each day’s driving.
Most importantly, all hitch nuts and bolts
should be tight.
NOTICE
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
conditioner and stop the vehicle in a
safe area to cool down the engine.

[ Do not switch off the engine while
the coolant gauge indicates over-
heating.
(Keep the engine idle to cool down
the engine)

[ When towing check transmission
fluid more frequently.

[ If your vehicle is not equipped with
an air conditioner, you should install
a condenser fan to improve engine
performance when towing a trailer.

If your temperature gauge indicates
overheating, you experience a loss of
power, or hear loud pinging or knocking,
the engine may be overheating. If this
happens, you should:
1. Pull off the road and stop as soon as it is safe to do so.
2. Shift the gear to P (Park) 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 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.
WARNING
While the engine is running,
keep hands, clothing and tools
away from the moving parts
such as the cooling fan and
drive belt to prevent serious
injury. 4. Check for coolant leaking from the
radiator, hoses or under the vehicle. (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 call the
nearest authorized HYUNDAI dealer
for assistance.
WARNING
Never remove the engine
coolant cap and/or water-
cooled intercooler coolant
cap or the drain plug while 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 removing the coolant 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.
IF THE ENGINE OVERHEATS

Emergency situations8-8
6. If you cannot find the cause of the overheating, wait until the engine
temperature 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
overheating happens again, call
an authorized HYUNDAI dealer for
assistance. CAUTION

[Serious loss of coolant indicates
a leak in the cooling system and
have the system be checked by an
authorized 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. It may require several
refilling cycles to properly fill the
engine cooling system. If necessary,
an authorized HYUNDAI dealer
should be consulted to perform this
task.

Checking the engine oil and
filter
OCN7092026

[ The lubrication, rust prevention,
cooling, and cleaning effect of the
engine oil will gradually degrade
during its use. Have the engine oil
and filter changed by an authorized
HYUNDAI dealer according to the Oil
Life Management System function
or the Maintenance Schedule at the
beginning of this chapter.

[ If the maintenance schedule to
replace engine oil is exceeded,
the engine oil performance may
deteriorate, and the engine condition
may be affected. Therefore, replace
the engine oil according to the
maintenance schedule.

[ To keep the engine in optimal
condition, use the recommended
engine oil and filter. If the
recommended engine oil and filter are
not used, replace it according to the
maintenance schedule under severe
usage conditions.

[ The purpose of the maintenance
schedule for engine oil replacement
is to prevent oil deterioration and it is
irrelevant to oil consumption. Check
and refill engine oil regularly.
Information
When the oil pressure is low due to
insufficient engine oil, the Engine
Oil Pressure (
) warning light will
illuminate. In addition, the enhanced
engine protection system, which limits
the engine’s power is activated and the
Malfunction Indicator Lamp (
) will
illuminate when the vehicle is driven in
this state continuously. When oil pressure
is restored, the Engine Oil Pressure
warning light will turn off and the engine
power will no longer be limited.
However, for gasoline 2.5 turbo engine
and 2.5 gdi engine, when the engine oil
pressure is restored, the warning light and
the enhanced engine protection system will
turn off after the engine is restarted.
CAUTION
The engine oil is very hot immediately
after the vehicle has been driven and
can cause burns during replacement.
Replace the engine oil after the engine
oil has cooled down.
WARNING
CALIFORNIA PROPOSITION 65
WARNING
Engine oil contains chemicals known to
the State of California to cause cancer,
birth defects and reproductive harm.
Used engine oil may cause irritation or
cancer of the skin if left in contact with
the skin for prolonged periods of time.
Always protect your skin by washing
your hands thoroughly with soap and
warm water as soon as possible after
