Maintenance07
The high-pressure cooling system
has a reservoir filled with the year-
round antifreeze coolant. The reser-
voir is already filled at the factory.
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
region.

operating, but when the
engine and radiator are hot,
do not remove the radiator
cap or the drain the plug. Hot
coolant and steam may blow
out under pressure, causing a
serious injury.
The electric motor (of
the cooling fan) is
controlled by the
engine coolant tem-
perature, refrigerant
pressure and driving speed. It
may operate, even when the
engine is not running. Use
extreme caution, when working
near the cooling fan blades. So,
you are not injured by the fan-
blade rotation. As the engine
coolant temperature decreases,
the electric motor will automati-
cally turn off. This is a normal.
When your vehicle is equipped
with GDI, the electric motor (of
the cooling fan) may operate
until the negative battery cable
is disconnected.
WARNING
Removing the radia-
tor cap
Never attempt to remove the radiator cap while the engine
is running, or when the engine
is hot. This may damage the
cooling system and the
engine, resulting in a serious
personal injury due to the 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 slowly turn
it in a counterclockwise direc-
tion to the first stop. Step back
while the pressure is released
from the cooling system.
When you are sure all the pres-
sure is released, press down
on the cap over a thick towel,
and turn it in a counterclock-
wise direction to remove it.

Maintenance07
Changing the coolant
Have coolant changed by an author-
ized EQUUS dealer in accordance
with the Maintenance Schedule, as
specified in the beginning of this
chapter.
Cover a thick cloth around the
radiator cap, before refilling the
coolant, in order to prevent the
coolant spillage over the engine
parts, such as the generator.
NOTICE
OVI075005N
Radiator cap
Do not remove the radiator cap,
when the engine and radiator
are hot. Hot coolant and steam
may blow out under pressure
and burn your skin, causing a
serious injury.
WARNING
- Coolant
Do not fill the radiator coolant or antifreeze in the washer
fluid reservoir.
Radiator coolant may obscure your visibility, when sprayed
on the windshield. This may
cause loss of vehicle control,
or damage the paint and body
trim.

Maintenance
Checking the washer fluid
level
The washer fluid reservoir is trans-
parent, so that you can visually
check the washer fluid level.
If necessary, add the washer fluid.
Plain water may be used, when the
washer fluid is unavailable. However,
you may add antifreezing solvents to
the fluid to prevent it from freezing,
before driving at a cold temperature.

The washer fluid containsome amounts of alcohol.
Thus, it is flammable under
certain circumstances. Keep
the washer fluid or the reser-
voir away from any sparks or
flames. This may damage the
vehicle, or injure the occu-
pants.
to humans and animals. Do
not drink and avoid contact-
ing with the washer fluid. This
may cause a serious injury or
death.
WARNING

To assure the proper engine and powertrain performance and durability, use
only lubricants of the proper quality.
The proper lubricants also promote engine efficiency, leading to a better fuel
economy.
These lubricants and fluids are recommended for use in your vehicle.

2Engine oils, labeled as Energy Conserving Oil, are now available. Along with other
additional benefits, they contribute to fuel economy by reducing the amount of fuel
necessary to overcome engine friction. Often, these improvements are difficult to
measure in everyday driving, but in a year’s time, they significantly reduce costs and
deliver energy savings.
*
3When the API service SM engine oil is not available in your country, you are able to use API service SL.
