1. Start the engine.Then, check the following operations are car-
ried correctly.
2. Vehicle-to-vehicle distance control mode is displayed in speed-
ometer illuminates when ON/OFF switch is pressed “ON” for
less than 1.5 seconds and ready for operation.The illumination
goes off when ON/OFF switch is turned to OFF.
3. “CRUISE” illumination and ICC system display go off when the
key switch is turned to OFF while ON/OFF switch is ON
(“CRUISE” illumination is ON and vehicle-to-vehicle distance
control mode is ready for operation).
Check For ACCEL/RES, COAST/SET, CANCEL Switches
1. Check if ACCEL/RES, COAST/SET, CANCEL switches are operated smoothly.
2. Check if buttons come up as hand is released from the buttons.
Check For Distance Switch
1. Start the engine.
2. Press the ON/OFF switch for less than 1.5 seconds.
3. Press the DISTANCE switch.
4. Check if the set distance indicator changes display in order of:
(long)→(middle)→(short).
NOTE:
The set distance indicator shows 'long' immediately after the engine starts.
CONVENTIONAL (FIXED SPEED) CRUISE CONTROL MODE
Set Checking
1. Press the ON/OFF switch for more than 1.5 seconds.
2. Drive the vehicle between 25 MPH (40 km/h for CANADA models) and 90 MPH (144 km/h for CANADA
models).
3. Push the COAST/SET switch.
4. Confirm that the desired speed is set as hand is released from the COAST/SET switch.

Check For Increase Of The Cruising Speed
1. Set the conventional (fixed speed) cruise control mode at desired speed.
2. Check if the set speed increases by 1 MPH (1.6 km/h for CANADA models) as ACCEL/RES switch is
pushed.
NOTE:

If the ACCEL/RES switch is kept lifting up during cruise control driving, the vehicle speed increases until
the switch is released.

The maximum set speed is 90 MPH (144 km/h for CANADA models).
Check For Decrease Of The Cruising Speed
1. Set the conventional (fixed speed) cruise control mode at desired speed.
2. Check if the set speed decreases by 1 MPH (1.6 km/h for CANADA models) as COAST/SET switch is
pushed.
NOTE:

Conventional (fixed speed) cruise control mode is automatically turned off when the driving speed lowers
to 20 MPH (32 km/h for CANADA models) due to the deceleration of the vehicle ahead.

The lowest set speed is 25 MPH (40 km/h for CANADA models).
Check For The Cancellation Of Conventional (Fixed Speed) Cruise Control Mode (Normal
Driving Condition) In The Following Cases:
Refer.toACS-9, "Check For The Cancellation Of Vehicle-To-Vehicle Distance Control Mode (Normal Driving
Condition) In The Following Cases:"
Check For Restoring The Speed That Is Set By Conventional (Fixed Speed) Cruise Control
Mode Before ICC Cancellation
Refer to.ACS-9, "Check For Restoring The Speed That Is Set By Vehicle-To-Vehicle Distance Control Mode
Before Cancellation"
Check For ON/OFF Switch
1. Start the engine.Then, check the following operations are car-
ried correctly.
2. “CRUISE” lamp (green) illuminates and ICC system indicator
goes off when ON/OFF switch is pressed “ON” for more than 1.5
seconds, and then ready for operation. The illumination goes off
when ON/OFF switch is turned to OFF.
3. “CRUISE” illumination go off when the key switch is turned to
OFF while ON/OFF switch is ON.
Check For ACCEL/ RES, COAST/SET, CANCEL Switches
1. Check if ACCEL/RES, COAST/SET, CANCEL switches are operated smoothly.
2. Check if buttons come up as hand is released from the buttons.

Changing A/T FluidACS0079Z
1. Warm up ATF.
2. Stop engine.
3. Loosen the level gauge bolt.
4. Drain ATF from drain plug and refill with new ATF. Always refill
same volume with drained fluid.

To replace the ATF, pour in new fluid at the charging pipe with
the engine idling and at the same time drain the old fluid from
the radiator cooler hose return side.

When the color of the fluid coming out is about the same as
the color of the new fluid, the replacement is complete. The
amount of new transmission fluid to use should be 30 to 50%
increase of the stipulated amount.
CAUTION:

Use only Genuine Nissan Matic J ATF. Do not mix with other fluid.

Using automatic transmission fluid other than Genuine Nissan Matic J ATF will cause deteriora-
tion in drive ability and automatic transmission durability, and may damage the automatic trans-
mission, which is not covered by the warranty.

When filling ATF, take care not to splash heat generating parts such as exhaust with ATF.

Do not reuse drain plug gasket.
5. Run engine at idle speed for 5 minutes.
6. Check fluid level and condition. Refer to AT- 1 2 , "
Checking A/T Fluid" . If fluid is still dirty, repeat step 2
through 5.
7. Install the removed A/T fluid level gauge in the A/T fluid charging pipe.
8. Tighten the level gauge bolt.
Checking A/T FluidACS007A0
1. Warm up engine.
2. Check for fluid leakage.
3. Loosen the level gauge bolt.
4. Before driving, fluid level can be checked at fluid temperatures
of 30 to 50°C (86 to 122°F) using “COLD” range on A/T fluid
level gauge as follows.
a. Park vehicle on level surface and set parking brake.
b. Start engine and move selector lever through each gear posi-
tion. Leave selector lever in “P” position.
c. Check fluid level with engine idling.
d. Remove A/T fluid level gauge and wipe clean with lint-free
paper.
CAUTION:
When wiping away the A/T fluid level gauge, always use
lint-free paper, not a cloth one.A/T fluid: Genuine Nissan Matic J ATF
