General MaintenanceELS000AL
General maintenance includes those items which should be checked during the normal day-to-day operation
of the vehicle. They are essential if the vehicle is to continue operating properly. The owners can perform the
checks and inspections themselves or they can have their NISSAN dealers do them for a nominal charge.
OUTSIDE THE VEHICLE
The maintenance items listed here should be performed from time to time, unless otherwise specified.
INSIDE THE VEHICLE
The maintenance items listed here should be checked on a regular basis, such as when performing periodic maintenance, cleaning the
vehicle, etc.
UNDER THE HOOD AND VEHICLE
The maintenance items listed here should be checked periodically e.g. each time you check the engine oil or refuel.Item Reference page
TiresCheck the pressure with a gauge periodically when at a service station, includ-
ing the spare, and adjust to the specified pressure if necessary. Check carefully
for damage, cuts or excessive wear.—
Windshield wiper
bladesCheck for cracks or wear if not functioning correctly. —
Doors and engine
hoodCheck that all doors, the engine hood, the trunk lid and back door operate prop-
erly. Also ensure that all latches lock securely. Lubricate if necessary. Make sure
that the secondary latch keeps the hood from opening when the primary latch is
released.
When driving in areas using road salt or other corrosive materials, check for
lubrication frequently.BL-12
, BL-18
Tire rotationTires should be rotated every 5,000 km (3,000 miles).MA-41
Item Reference page
LampsMake sure that the headlamps, stop lamps, tail lamps, turn signal lamps, and
other lamps are all operating properly and installed securely. Also check head-
lamp aim.—
Warning lamps and
chimesMake sure that all warning lamps and buzzers/chimes are operating properly. —
Steering wheelCheck that it has the specified play.
Check for changes in the steering conditions, such as excessive free play, hard
steering or strange noises.
Free play: Less than 35 mm (1.38 in)—
Seat beltsCheck that all parts of the seat belt system (e.g. buckles, anchors, adjusters and
retractors) operate properly and smoothly, and are installed securely. Check the
belt webbing for cuts, fraying, wear or damage.MA-45

Periodic MaintenanceELS000AM
The following tables show the normal maintenance schedule. Depending upon weather and atmospheric con-
ditions, varying road surfaces, individual driving habits and vehicle usage, additional or more frequent mainte-
nance may be required.
Periodic maintenance beyond the last period shown on the tables requires similar maintenance.

Abbreviations: I = Inspect and correct or replace as necessary, R = Replace,.
NOTE:

Maintenance items with “ ” should be performed more frequently according to “Maintenance Under Severe Driving
Conditions”.

(1)Periodic maintenance is not required. However, if valve noise increases, check valve clearance.

(2) Replace the drive belt if found damaged or if the auto belt tensioner reading reaches the maximum limit.

(3) First replace at 90,000 Km (54,000 miles)/60 months, then every 60,000 km (36,000 miles)/48 months. Perform "I"
(Checking the mixture ratio and correcting the mixture ratio if necessary) at the middle of replacement interval.

RECOMMENDED FLUIDS AND LUBRICANTSPFP:00000
Fluids and LubricantsELS000C8
*1: For further details, see “SAE Viscosity Number”.
*2: Never use API CG-4.
*3: Use Genuine Nissan Anti-freeze Coolant (L250) or equivalent in its quality, in order to avoid possible aluminum corrosion w ithin the
engine cooling system caused by the use of non-genuine engine coolant.
Note that any repairs for the incidents within the engine cooling system while using non-genuine engine coolant may not be
covered by the warranty even if such incidents occurred during the warranty period.
*4: Contact a Nissan dealership for more information regarding suitable fluids, including recommended brand(s) of DEXRON
TM III/MER-
CONTM Automatic Transmission Fluid.

Engine Coolant Mixture RatioELS000AN
The engine cooling system is filled at the factory with a high-quality,
year-round and extended life engine coolant. The high quality engine
coolant contains the specific solutions effective for the anti-corrosion
and the anti-freeze function. Therefore, additional cooling system
additives are not necessary.
CAUTION:

When adding or replacing coolant, be sure to use only Gen-
uine Nissan Anti-freeze Coolant (L250) or equivalent.
Because L250 is premixed type coolant.
The use of other types of engine coolant may damage your
cooling system.

When checking the engine coolant mixture ratio by the coolant
hydrometer, use the chart below to correct your hydrometer reading (specific gravity) according to coolant
temperature.
Mixed coolant specific gravity
Unit: specific gravity
WARNING:
Never remove the radiator cap when the engine is hot. Serious burns could be caused by high pres-
sure fluid escaping from the radiator. Wait until the engine and radiator cool down.

Checking Drive BeltsELS000ZC
WARNING:
Be sure to perform when the engine is stopped.

Make sure that the indicator (single line notch on fixed side) of drive belt auto-tensioner is within the pos-
sible use range (between three line notches on moving side).
NOTE:

Check the drive belt auto-tensioner indicator (single line notch on fixed side) when the engine is cold.

When new drive belt is installed, the indicator (single line notch on fixed side) should be within the
range “A” in the figure.

Visually check entire belt for wear, damage or cracks.

If the indicator (single line notch on fixed side) is out of possible use range or belt is damaged, replace
drive belt.
Tension AdjustmentELS000ZD
Belt tensioning is not necessary, as it is automatically adjusted by drive belt auto-tensioner.
Changing Engine CoolantELS000ZE
WARNING:

To avoid being scalded, do not change engine coolant when engine is hot.

Wrap a thick cloth around radiator cap and carefully remove the cap. First, turn the cap a quarter
of a turn to release built-up pressure. Then turn the cap all the way.

Be careful not to allow engine coolant to contact drive belt.
DRAINING ENGINE COOLANT
1. Remove RH and LH undercovers.
2. Open radiator drain plug at the bottom of radiator, and then
remove radiator cap.
