• Before starting engine, check oil/fluid levels incl
uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-11, "FOR USA AND CANADA : Fluids and Lubricants"
.
• Use procedure below to check for fuel leakage.
• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak-
age at connection points.
• Start engine. With engine speed increased, check again for fuel leakage at connection points.
• Run engine to check for unusual noise and vibration. NOTE:
If hydraulic pressure inside timing chain tensioner dr ops after removal and installation, slack in the guide
may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop
after hydraulic pressure rises.
• Warm up engine thoroughly to make sure there is no leak age of fuel, exhaust gas, or any oils/fluids including
engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec- ified level, if necessary.

Diagnosis DescriptionINFOID:0000000009956487
AUTO ACTIVE TEST
Description
In auto active test mode, the IPDM E/R sends a drive signal to the follo wing systems to check their operation.
• Front wiper (LO, HI)
• Front fog lamps
• Parking lamps
• Side marker lamps
• Tail lamps
• License plate lamps
• Daytime running lamps
• Headlamps (LO, HI)
• A/C compressor
• Cooling fans (LO, HI)
Operation Procedure
CAUTION:
Do not start the engine.
NOTE:
When auto active test is performed with hood opened, sprinkle water on windshield before hand.
NOTE:
• If auto active test mode cannot be actuat ed, check door switch system. Refer to DLK-100,
"Component Function Check".
• When auto active test mode has to be cancelled halfway through test, turn ignition switch OFF.
1. Close the hood and lift the wiper arms from the windshield. (Prevent windshield damage due to wiper
operation)
2. Turn ignition switch OFF.
3. Turn the ignition switch ON, and within 20 seconds, press the front door switch LH 10 times. Then turn the ignition switch OFF.
4. Turn the ignition switch ON within 10 seconds. Af ter that the horn sounds once, and the auto active test
starts.
5. After a series of the following operations is repeated 3 times, auto active test is completed.
Inspection in Auto Active Test Mode
When auto active test mode is actuated, the following operation sequence is repeated 3 times.
*: Outputs duty ratio of 50% for 5 seconds → duty ratio of 100% for 5 seconds on the cooling fan control module.

Concept of auto active test
• IPDM E/R starts the auto active test with the door
switch signals transmitted by BCM via CAN communica-
tion. Therefore, the CAN communication line between IPDM E/R and BCM is considered normal if the auto
active test starts successfully.
• The auto active test facilitates troubleshooting if any systems controlled by IPDM E/R cannot be operated.
Diagnosis chart in auto active test mode
CONSULT Function (IPDM E/R)INFOID:0000000009956488
CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentiall y causing a discharged battery and a no-start condition.

TOW TRUCK TOWING
Tow Truck TowingINFOID:0000000009463008
CAUTION:
• Never tow a CVT model with the rear wheels raised and the front wheels on the ground. This may
cause serious and expensive damage to the transaxle. If it is necessary to tow the vehicle with the
rear wheels raised, always use towi ng dollies under the front wheels.
• Never tow a CVT model from the rear (that is backw ard) with four wheels on the ground. This may
cause serious and expensive damage to the transaxle.
NISSAN recommends that the vehicle be towed with the driving
(front) wheels off the ground.
CAUTION:
• Always release the parking brake when towing the vehicle with the front wheels raised with the rear wheels on the
ground.
Vehicle Recovery (Freeing a Stuck Vehicle)INFOID:0000000009463009
FRONT
WARNING:
• Stand clear of a stuck vehicle.
• Do not spin your tires at high speed. This could cause them to explode and result in serious injury.
Parts of your vehicle could also overheat and be damaged.
CAUTION:
• Tow chains or cables must be attached only to the vehicle recovery hooks or main structural mem-
bers of the vehicle. Otherwise, the vehicle body will be damaged.
• Do not use the vehicle tie downs to free a vehicle stuck in sand, snow, mud, etc. Never tow the vehi-
cle using the vehicle tie downs or recovery hooks.
• Always pull the cable straight out from the front of the vehicle. Never pull on the hook at an angle.
• Pulling devices should be routed so they do not touch any part of the suspension, steering, brake or
cooling systems.
• Pulling devices such as ropes or canvas straps ar e not recommended for use in vehicle towing or
recovery.
CVT
To tow a vehicle equipped with a CVT, an appropriate vehicle dolly MUST be placed under the towed vehicle's
drive wheels. Always follow the dolly manufacture's recommendations when using their product.
If the vehicle is stuck in sand, snow , mud, etc., use the following procedure:
1. Turn off the Vehicle Dynamic Control System.
2. Make sure the area in front and behind the vehicle is clear of obstructions.
