CHANGING ENGINE COOLANT
An authorized NISSAN dealer can change
the engine coolant. The service procedure
is found in NISSAN's Service Manual.
Improper servicing can result in reduced
heater performance and engine over-
heating.
WARNING
cTo avoid the danger of being
scalded, never change the coolant
when the engine is hot.
cNever remove the radiator cap when
the engine is hot. Serious burns
could be caused by high pressure
fluid escaping from the radiator.
cAvoid direct skin contact with used
coolant. If skin contact is made,
wash thoroughly with soap or hand
cleaner as soon as possible.
cKeep coolant out of reach of children
and pets.
CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface and
apply the parking brake.
2. Start the engine and let it idle until it
reaches operating temperature.
3. Turn off the engine.Wait more than 10
minutes for the oil to drain back into
the oil pan.
4. Remove the dipstick and wipe it clean.
Reinsert it all the way.

5. Remove the dipstick again and check the
oil level. It should be between the H
(High) and L (Low) marks. If the oil level
is below the L (Low) mark, remove the oil
filler cap and pour recommended oil
through the opening.Do not overfill.
6. Recheck the oil level with the dipstick.
It is normal to add some oil between oil
maintenance intervals or during the
break-in period, depending on the sever-
ity of operating conditions.
CAUTION
Oil level should be checked regularly.
Operating the engine with an insuffi-
cient amount of oil can damage the
engine, and such damage is not cov-
ered by warranty.
CHANGING ENGINE OIL
1. Park the vehicle on a level surface and
apply the parking brake.
2. Start the engine and let it idle until it
reaches operating temperature, then turn
it off.
3. Remove the oil filler cap.
4. Place a large drain pan under the drain
plug.
5. Remove the drain plug with a wrench and
completely drain the oil.

If the oil filter is to be changed, remove
and replace it at this time. See ``Chang-
ing engine oil filter'' later in this section.
CAUTION
Be careful not to burn yourself. The
engine oil may be hot.
c
Waste oil must be disposed of properly.
cCheck your local regulations.
6. Clean and reinstall the drain plug and a
new washer. Securely tighten the drain
plug with a wrench.Drain plug tightening torque:
22 to 29 ft-lb
(29 to 39 Nzm)
Do not overtighten.
7. Refill the engine with a recommended oil
through the oil filler opening, then install
the oil filler cap securely.
See the ``Technical and consumer informa-
tion'' section for drain and refill capacity.
The drain and refill capacity depends on the
oil temperature and drain time. Use these
specifications for reference only. Always
use the dipstick to determine when the
proper amount of oil is in the engine.
8. Start the engine. Check for leakage
around the drain plug. Correct as re-
quired.
9. Turn the engine off and wait several
minutes. Check the oil level with the
dipstick. Add engine oil if necessary.
WARNING
cProlonged and repeated contact with
used engine oil may cause skin can-
cer.
cTry to avoid direct skin contact with
used oil. If skin contact is made,
wash thoroughly with soap or hand
cleaner as soon as possible.
cKeep used engine oil out of reach of
children.

WARNING
cWhen the engine is running, keep
hands, jewelry and clothing away
from any moving parts such as the
cooling fan and drive belts.
cAutomatic transmission fluid is poi-
sonous and should be stored care-
fully in marked containers out of the
reach of children.
TEMPERATURE CONDITIONS
FOR CHECKING
cThe fluid level should be checked using
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 122É and 176ÉF
(50É to 80ÉC).
cThe fluid can be checked at fluid tem-
peratures of 86É 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
selector lever through each gear range.
Move the shift selector lever to P (Park)
after you have moved it through all
ranges.

3. Check the fluid level with the engine
idling.
4. Remove the dipstick and wipe it clean
with lint-free paper.
5. Reinsert the dipstick into the dipstick
tube as far as it will go.
6. Remove the dipstick and note the read-
ing. If the level is at the low side of either
range, add fluid through the dipstick tube.
CAUTION
DO NOT OVERFILL. USE ONLY NISSAN
Matic `D' (Continental U.S. and Alaska)
or Canada NISSAN Automatic Trans-
mission Fluid. DexronŸ III/MerconŸ or
equivalent may also be used. Outside
the continental United States and
Alaska contact an authorized NISSAN
dealership for more information re-
garding suitable fluids, including rec-
ommended brand(s) of DexronŸ
III/MerconŸ Automatic Transmission
Fluid.
NOTE:
If the vehicle has been driven for a long
time at high speeds, or in city traffic in
hot weather, or if it is being used to pull
a trailer, the accurate fluid level cannot
be read. You should wait until the fluid
has cooled down (about 30 minutes).The fluid level should be checked using the
HOT MAX range on the power steering fluid
reservoir at fluid temperatures of 122É to
176ÉF (50É to 80ÉC) or using the COLD
MAX range on the power steering fluid
reservoir at fluid temperatures of 32É to
86ÉF (0 to 30ÉC).
CAUTION
cDO NOT OVERFILL.
cRecommended fluid is Genuine
NISSAN PSF II or equivalent.

cDo not operate the vehicle if the fluid
in the battery is low. Low battery
fluid can cause a higher load on the
battery which can generate heat, re-
duce battery life, and in some cases
lead to an explosion.
cWhen working on or near the battery,
always wear suitable eye protection
and remove all jewelry.
cBattery posts, terminals and related
accessories contain lead and lead
compounds. Wash hands after han-
dling.
cKeep the battery out of the reach of
children.1. To remove the cap, gently pry between
the battery cap and cover as illustrated.
Use a cloth to protect the battery case.2. Check the fluid level in each cell.
If it is necessary to add fluid, add only
distilled water to bring the level up to the
OK level indicator in each filler opening.
Do not overfill.
Vehicles operated in high temperatures
or under severe conditions require fre-
quent checks of the battery fluid level.
JUMP STARTING
If jump starting is necessary, see the ``In
case of emergency'' section of this owner's
manual. If the engine does not start by jump
starting, the battery may have to be re-
