The engine cooling system is filled at the
factory with a high-quality, year-round, anti-
freeze coolant solution. The anti-freeze so-
lution contains rust and corrosion inhibitors,
therefore additional cooling system addi-
tives are not necessary.
CAUTION
When adding or replacing coolant, be
sure to use only an ethylene glycol
anti-freeze with the proper mixture ra-
tio. Examples are shown below:

The use of other types of coolant solu-
tions may damage your cooling system.
The radiator is equipped with a pressure
cap. Use a NISSAN genuine cap or its
equivalent when replacement is re-
quired.
Never remove the radiator cap when the
engine is hot. Wait until the engine andradiator cool down. Serious burns could
be caused by high pressure fluid escap-
ing from the radiator. See precautions in
``If your vehicle overheats'' found in the
``In case of emergency'' section.
CHECKING ENGINE COOLANT
LEVEL
With coolant reservoir
Check the coolant level in the reservoir
when the engine is cold. If the coolant level
is below ``MIN'', add coolant up to the
``MAX'' level. If the reservoir is empty, check
the coolant level in the radiatorwhen the
engine is cold.If there is insufficient cool-
ant in the radiator, fill the radiator with
coolant up to the filler opening and also add
it to the reservoir up to the ``MAX'' level.

the ``HOT'' range on the dipstick after the
following conditions have been met:
Ð The engine should be warmed up to
operating temperature.
Ð The vehicle should be driven at least 5
minutes.
Ð The automatic transmission fluid should
be warmed to between 122 and 176ÉF
(50 to 80ÉC).
cThe fluid can be checked at fluid tem-
peratures of 86 to 122ÉF (30 to 50ÉC)
using the ``COLD'' range on the dipstick
after the engine is warmed up and before
driving. However, the fluid should be
re-checked using the ``HOT'' range.
1. Park the vehicle on a level surface and
set the parking brake.
2. Start the engine and then move the shift
lever through each gear range. Move the
