NOTE:
 When data link connector branch line is open, transmission and reception of CAN communication signals
are not affected. Therefore, no symptoms occur. However, be sure to repair malfunctioning circuit.
 The model (all units on CAN communication system are Diag on CAN) cannot perform CAN diagnosis with
CONSULT-III if the following error occurs. The error is judged by the symptom.
EPS control unit Normal operation.
Combination meter Shift position indicator and OD OFF indicator turn OFF.
 Warning lamps turn ON.

RECOMMENDED FLUIDS AND LUBRICANTS
Fluids and LubricantsINFOID:0000000003858223
*1: For further details, see “SAE Viscosity Number”.
*2: Use Genuine NISSAN Engine Coolant or equivalent in its quality, in order to avoid possible aluminum corrosion within 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.
*3: Using transmission fluid other than Genuine NISSAN CVT fluid NS-2 will damage the CVT, which is not covered by the war-
ranty.
*4: DEXRON
™ VI type ATF can be used.
*5: Never mix different types of fluids (DOT3 and DOT4).

ENGINE MAINTENANCE
 Check if the reservoir tank engine coolant level is within the “MIN”
to “MAX” when the engine is cool.
 Adjust the engine coolant level as necessary.
LEAKAGE
 To check for leakage, apply pressure to the cooling system with the
radiator cap tester (commercial service tool) (A) and radiator cap
tester adapter (commercial service tool) (B).
WARNING:
Never remove radiator cap when engine is hot. Serious burns
could occur from high-pressure engine coolant escaping from
radiator.
CAUTION:
Higher test pressure than specified may cause radiator dam-
age.
NOTE:
In a case that engine coolant decreases, replenish radiator with engine coolant.
 If anything is found, repair or replace damaged parts.
ENGINE COOLANT : DrainingINFOID:0000000003862450
WARNING:
 To avoid being scalded, never change engine coolant when the engine is hot.
 Wrap a thick cloth around radiator cap and carefully remove radiator cap. First, turn radiator cap a
quarter of a turn to release built-up pressure. Then turn radiator cap all the way.
1. Remove engine under cover.
2. Open radiator drain plug (1) at the bottom of radiator, and then
remove radiator cap.
When draining all of engine coolant in the system, open water drain plugs on cylinder block. Refer
to EM-110, "
Disassembly and Assembly".
3. Remove reservoir tank as necessary, and drain engine coolant and clean reservoir tank before installing.
4. Check drained engine coolant for contaminants such as rust, corrosion or discoloration.
If contaminated, flush the engine cooling system. Refer to MA-16, "
ENGINE COOLANT : Flushing".
ENGINE COOLANT : RefillingINFOID:0000000003862451
1. Install reservoir tank if removed, and radiator drain plug.
CAUTION:
Be sure to clean drain plug and install with new O-ring.

POWER STEERING FLUID AND LINES : Inspection
INFOID:0000000003862441
Check fluid level in reservoir tank with engine off.
Fluid levels at HOT and COLD are different. Do not confuse them.
CAUTION:
 Do not overfill.
 Recommended fluid is Genuine NISSAN PSF or equivalent.
Refer to MA-11, "
Fluids and Lubricants".
 Check lines for improper attachment, leaks, cracks, damage,
loose connections, chafing and deterioration.
 Check rack boots for accumulation of power steering fluid.
AXLE AND SUSPENSION PARTS
AXLE AND SUSPENSION PARTS : InspectionINFOID:0000000003858316
Check front and rear axle and suspension parts for excessive play,
cracks, wear or other damage.
 Shake each wheel to check for excessive play.
 Check wheel bearings for smooth operation.
 Check axle and suspension nuts and bolts for looseness.
 Check strut (shock absorber) for oil leakage or other damage.
 Check suspension ball joint for grease leakage and ball joint dust
cover for cracks or other damage.
