CHECKING ENGINE COOLANT LEVEL
Check the coolant levelin the reservoir
when the engine is cold. If the coolant
level is below MIN
, open the reservoir
tank cap and add coolant up to the MAX
level. If the reservoir tank is empty,
check the coolant level in the radiator
when the engine is cold. If there is
insufficient coolant in the radiator, fill the
radiator with coolant up to the filler
opening and also add it to the reservoir
tank up to the MAX level
.
Tighten the cap securely after adding
engine coolant.
If the cooling system requires coolant
frequently, have it checked. It is recom- mended you visit a NISSAN dealer for
this service.
CHANGING ENGINE COOLANT
It is recommended that major cooling
system repairs be performed by a NISSAN
dealer. The service procedures can be
found in the appropriate NISSAN Service
Manual.
Improper servicing can result in re-
duced heater performance and engine
overheating.
WARNING
.
To avoid the danger of being
scalded, never change the cool-
ant when the engine is hot.
. Never remove the radiator cap or
coolant reservoir cap when the
engine is hot. Serious burns could
be caused by high pressure fluid
escaping from the radiator.
. Avoid direct skin contact with
used coolant. If skin contact is
made, wash thoroughly with soap
or hand cleaner as soon as pos-
sible.
. Keep coolant out of reach of
children and pets. Engine coolant must be disposed of
properly. Check your local regulations.

CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface andapply the parking brake.
2. Run the engine until it reaches oper- ating temperature.
3. Turn off the engine. Wait more than
15 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 within the
range
. If the oil level is below,
remove the oil filler cap and pour
recommended oil through the open- ing.
Do not overfill
.
6. Recheck 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 se-
verity 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
covered by warranty.
CHANGING ENGINE OIL AND FILTER
Vehicle set-up

Engine oil and filter
1. Place a large drain pan under thedrain plug.
2. Remove the oil filler cap.
3. Remove the drain plug
with a
wrench and completely drain the oil.
CAUTION
Be careful not to burn yourself, as
the engine oil is hot.
.Waste oil must be disposed of properly.
.Check your local regulations.
4. (Perform steps 4 to 7 only when the engine oil filter change is needed.)
Loosen the oil filter
with an oil filter
wrench. Remove the oil filter by turn-
ing it by hand.
5. Wipe the engine oil filter mounting surface with a clean rag.
CAUTION
Be sure to remove any old rubber
gasket remaining on the mounting
surface of the engine. Failure to do
so could lead to engine damage.
6. Coat the gasket on the new filter with clean engine oil.
7. Screw in the oil filter clockwise until a slight resistance is felt, then tighten
additionally more than 2/3 turn.
Oil filter tightening torque:11 to 15 ft-lb
(15 to 21 N·m)
8. Clean and re-install the drain plug with a new washer. Securely tighten
the drain plug with a wrench.
Drain plug tightening torque:22 to 29 ft-lb
(29 to 39 N·m) Do not use excessive force.
9. Refill engine with recommended oil and install the oil filler cap securely.
CAUTION
The dipstick must be inserted in
place to prevent oil spillage from
the dipstick hole while filling the
engine with oil.
See “Capacities and recommended
fluids/lubricants” (P.10-2) for drain
and refill capacity. The drain and refill
capacity depends on the oil tempera-
ture and drain time. Use these speci-
fications for reference only. Always
use the dipstick to determine the
proper amount of oil in the engine.
10. Start the engine and check for leak- age around the drain plug and the oil
filter. Correct as required.
11. Turn the engine off and wait more than 15 minutes. Check the oil level
with the dipstick. Add engine oil if
necessary.

REPLACING SPARK PLUGS
If replacement is required, it is recom-
mended you visit a NISSAN dealer for this
service.
Iridium-tipped spark plugs
It is not necessary to replace the iridium-
tipped spark plugs as frequently as the
conventional type spark plugs since they
will last much longer. Follow the main-
tenance schedule shown in the “9. Main-
tenance and schedules” section, but do
not reuse them by cleaning or regapping.
Always replace spark plugs with recom-
mended or equivalent ones.
SPARK PLUGS

It is recommended you visit a NISSAN
dealer if checking or replacement is
required.If the brakes do not operate properly,
have the brakes checked. It is recom-
mended that you visit a NISSAN dealer for
this service.
SELF-ADJUSTING BRAKES
Your vehicle is equipped with self-adjust-
ing brakes.
The disc-type brakes self-adjust every
time the brake pedal is applied.
WARNING
Have your brake system checked if
the brake pedal height does not
return to normal. It is recommended
you visit a NISSAN dealer for this
service.
BRAKE PAD WEAR WARNING
The disc brake pads have audible wear
warnings. When a brake pad requires
replacement, it will make a high pitched
scraping sound when the vehicle is in
motion. This scraping sound will first
occur only when the brake pedal is
depressed. After more wear of the brake
pad, the sound will always be heard even
if the brake pedal is not depressed. Have
the brakes checked as soon as possible if
the wear warning sound is heard.Under some driving or climate conditions,
occasional brake squeak, squeal or other
noise may be heard. Occasional brake
noise during light to moderate stops is
normal and does not affect the function
or performance of the brake system.
Proper brake inspection intervals
should be followed.
For additional infor-
mation, see the maintenance schedule
shown in the “9. Maintenance and sche-
dules” section.
BRAKE BOOSTER
Check the brake booster function as
follows:
1. With the engine off, depress and release the foot brake pedal more
than 20 times. When the foot brake
pedal movement (distance of travel)
remains the same from one pedal
application to the next, continue on
to the next step.
2. While depressing the foot brake pedal, start the engine.
3. With the foot brake pedal depressed, stop the engine. Keep the pedal de-
pressed for about 30 seconds.
4. Run the engine for 1 minute without depressing the foot brake pedal, then
turn it off. Depress the foot brake
pedal several times. The pedal travel
distance will decrease gradually with

9-2Maintenance and schedules
Some day-to-day and regular mainte-
nance is essential to maintain your vehi-
cle in good mechanical condition, as well
as its emission and engine performance.
It is the owner’s responsibility to make
sure that the scheduled maintenance, as
well as general maintenance, is per-
formed.
As the vehicle owner, you are the only one
who can ensure that your vehicle receives
the proper maintenance. You are a vital
link in the maintenance chain.
GENERAL MAINTENANCE
General maintenance includes those
items which should be checked during
normal day-to-day operation. They are
essential for proper vehicle operation. It is
your responsibility to perform these pro-
cedures regularly as prescribed.
Performing general maintenance checks
requires minimal mechanical skill and
only a few general automotive tools.
These checks or inspections can be done
by yourself, a qualified technician or, if you
prefer, a NISSAN dealer.
SCHEDULED MAINTENANCE
The maintenance items listed in this
section are required to be serviced at
regular intervals. However, under severe
driving conditions, additional or more
frequent maintenance will be required.
