engine NISSAN ARMADA 2015 1.G Repair Manual

WARNING
Overheating can result in reduced engine
power and vehicle speed. The reduced
speed may be lower than other traffic,
which could increase the chance of a col-
lision. Be especially careful when driving.
If the vehicle cannot maintain a safe driv-
ing speed, pull to the side of the road in a
safe area. Allow the engine to cool and
return to normal operation. For additional
information, refer to “If your vehicle over-
heats” in the “In case of emergency” sec-
tion of this manual.
CAUTION
Running the engine with the engine oil
pressure warning light on could cause se-
rious damage to the engine almost imme-
diately. Such damage is not covered by
warranty. Turn off the engine as soon as it
is safe to do so.
AUTOMATIC TRANSMISSION
WARNING
●Do not depress the accelerator pedal
while shifting from P (Park) or N (Neu-
tral) to R (Reverse) , or 1 (Low) . Always
depress the brake pedal until shifting is
completed. Failure to do so could cause
you to lose control and have an
accident.
● Cold engine idle speed is high, so use
caution when shifting into a forward or
reverse gear before the engine has
warmed up.
● Never shift to either the P (Park) or R
(Reverse) position while the vehicle is
moving forward and P (Park) or D
(Drive) position while the vehicle is re-
versing. This could cause an accident or
damage the transmission.
● Except in an emergency, do not shift to
the N (Neutral) position while driving.
Coasting with the transmission in the N
(Neutral) position may cause serious
damage to the transmission.
CAUTION
● When stopping the vehicle on an uphill
grade, do not hold the vehicle by de-
pressing the accelerator pedal. The foot
brake should be used for this purpose.
● Do not downshift abruptly on slippery
roads. This may cause a loss of control.
The automatic transmission in your vehicle is
electronically controlled to produce maximum
power and smooth operation.
The recommended operating procedures for this
transmission are shown on the following pages.
Follow these procedures for maximum vehicle
performance and driving enjoyment.

Shift lock release
If the battery is discharged, the shift lever may not
be moved from the P (Park) position even with the
brake pedal depressed.
To move the shift lever, release the shift lock. The
shift lever can be moved to N (Neutral) . However,
the steering wheel will be locked unless the igni-
tion switch is placed in the ON position (for
models with a steering lock mechanism) . This
allows the vehicle to be moved if the battery is
discharged.To push the shift lock release, complete the fol-
lowing procedure:
1. Place the ignition switch in the LOCK posi- tion and remove the key.
2. Apply the parking brake.
3. Remove the shift lock release cover as shown.
4. Use a protective cloth on the tip of a small screwdriver before inserting it in the shift
lock release slot and pushing down.
5. Move the shift lever to the N (Neutral) posi- tion while holding down the shift lock re-
lease.
6. Place the ignition switch in the ON position to unlock the steering wheel (for models with
a steering lock mechanism) .
7. Now the vehicle may be moved to the de- sired location.
If the shift lever cannot be moved out of P (Park) ,
have a NISSAN dealer check the automatic
transmission system as soon as possible.
WARNING
If the shift lever cannot be moved from the
P (Park) position while the engine is run-
ning and the brake pedal is depressed, the
stop lights may not work. Malfunctioning
stop lights could cause an accident injur-
ing yourself and others.
Accelerator downshift
— in D (Drive) position —
For passing or hill climbing, depress the accel-
erator pedal to the floor. This shifts the transmis-
sion down into a lower gear, depending on the
vehicle speed.

5-18Starting and driving

●Push the ON/OFF switch off. Both the
CRUISE indicator light and SET indicator
light in the vehicle information display go out.
The cruise control is automatically canceled and
the SET light in the vehicle information display
goes out if: ● You depress the brake pedal while pushing
the ACCEL/RES or SET/COAST switch.
The preset speed is deleted from memory.
● The vehicle slows down more than 8 mph
(13 km/h) below the set speed.
● You move the shift lever to N (Neutral) .
To reset at a faster cruising speed, use one of
the following three methods:
● Depress the accelerator pedal. When the
vehicle attains the desired speed, push and
release the COAST/SET switch.
● Push and hold the ACCEL/RES switch.
When the vehicle attains the speed you de-
sire, release the switch.
● Push and release the ACCEL/RES switch.
Each time you do this, the set speed in-
creases by about 1 mph (1.6 km/h). To reset at a slower cruising speed,
use one
of the following three methods:
● Lightly tap the brake pedal. When the ve-
hicle attains the desired speed, push the
COAST/SET switch and release it.
● Push and hold the COAST/SET switch. Re-
lease the switch when the vehicle slows to
the desired speed.
● Push and release the COAST/SET switch.
Each time you do this, the set speed de-
creases by about 1 mph (1.6 km/h).
To resume the preset speed, push and re-
lease the ACCEL/RES switch. The vehicle re-
turns to the last set cruising speed when the
vehicle speed is over 25 mph (40 km/h).CAUTION
During the first 1,200 miles (2,000 km),
follow these recommendations to obtain
maximum engine performance and ensure
the future reliability and economy of your
new vehicle. Failure to follow these rec-
ommendations may result in shortened
engine life and reduced engine
performance.
● Avoid driving for long periods at constant
speed, either fast or slow, and do not run the
engine over 4,000 RPM.
● Do not accelerate at full throttle in any gear.
● Avoid quick starts.
● Avoid hard braking as much as possible.
● Do not tow a trailer for the first 500 mi
(805 km) . Your engine, axle or other parts
could be damaged.
BREAK-IN SCHEDULE
Starting and driving5-21

Follow these easy-to-use Fuel Efficient Driving
Tips to help you achieve the most fuel economy
from your vehicle.1. Use Smooth Accelerator and Brake
Pedal Application
● Avoid rapid starts and stops.
● Use smooth, gentle accelerator and
brake application whenever possible.
● Maintain constant speed while commut-
ing and coast whenever possible.
2. Maintain Constant Speed
● Look ahead to try and anticipate and mini-
mize stops.
● Synchronizing your speed with traffic
lights allows you to reduce your number
of stops.
● Maintaining a steady speed can minimize
red light stops and improve fuel effi-
ciency.
3. Use Air Conditioning (A/C) at Higher
Vehicle Speeds
● Below 40 mph (64 km/h), it is more effi-
cient to open windows to cool the vehicle
due to reduced engine load. ●
Above 40 mph (64 km/h), it is more effi-
cient to use A/C to cool the vehicle due to
increased aerodynamic drag.
● Recirculating the cool air in the cabin
when the A/C is on reduces cooling load.
4.
Drive at Economical Speeds and Distances
● Observing the speed limit and not ex-
ceeding 60 mph (97 km/h) (where legally
allowed) can improve fuel efficiency due
to reduced aerodynamic drag.
● Maintaining a safe following distance be-
hind other vehicles reduces unnecessary
braking.
● Safely monitoring traffic to anticipate
changes in speed permits reduced brak-
ing and smooth acceleration changes.
● Select a gear range suitable to road con-
ditions.
5. Use Cruise Control
● Using cruise control during highway driv-
ing helps maintain a steady speed.
● Cruise control is particularly effective in
providing fuel savings when driving on flat
terrains.
6. Plan for the Shortest Route
● Utilize a map or navigation system to de-
termine the best route to save time. 7.
Avoid Idling
● Shutting off your engine when safe for
stops exceeding 30–60 seconds saves
fuel and reduces emissions.
8. Buy an Automated Pass for Toll Roads
● Automated passes permit drivers to use
special lanes to maintain cruising speed
through the toll and avoid stopping and
starting.
9. Winter Warm Up
● Limit idling time to minimize impact to fuel
economy.
● Vehicles typically need no more than
30 seconds of idling at start-up to effec-
tively circulate the engine oil before driv-
ing.
● Your vehicle will reach its ideal operating
temperature more quickly while driving
versus idling.
10. Keeping your Vehicle Cool
● Park your vehicle in a covered parking
area or in the shade whenever possible.
● When entering a hot vehicle, opening the
windows will help to reduce the inside
temperature faster, resulting in reduced
demand on your A/C system.
FUEL EFFICIENT DRIVING TIPS
5-22Starting and driving

●Keep your engine tuned up.
● Follow the recommended scheduled main-
tenance.
● Keep the tires inflated to the correct pres-
sure. Low tire pressure increases tire wear
and lowers fuel economy.
● Keep the wheels in correct alignment. Im-
proper alignment increases tire wear and
lowers fuel economy.
● For vehicles equipped with
, use 4H
or 4L position only when necessary. Four-
wheel drive operation lowers fuel economy.
● Use the recommended viscosity engine oil.
For additional information, refer to “Engine
oil and oil filter recommendations” in the
“Technical and consumer information” sec-
tion of this manual.
WARNING
● For 4WD equipped vehicles, do not at-
tempt to raise two wheels off the
ground and shift the transmission to
any drive or reverse position with the
engine running. Doing so may result in
drivetrain damage or unexpected ve-
hicle movement which could result in
serious vehicle damage or personal
injury.
● Do not attempt to test a 4WD equipped
vehicle on a 2-wheel dynamometer
(such as the dynamometers used by
some states, provinces or territories for
emissions testing) , or similar equip-
ment even if the other two wheels are
raised off the ground. Make sure you
inform test facility personnel that your
vehicle is equipped with 4WD before it
is placed on a dynamometer. Using the
wrong test equipment may result in
drivetrain damage or unexpected ve-
hicle movement which could result in
serious vehicle damage or personal
injury.
CAUTION
● Do not drive the vehicle in the 4H or 4LO
position on dry hard surface roads. Driv-
ing on dry, hard surfaces in 4H or 4LO
may cause unnecessary noise, tire wear
and increased fuel consumption.
If the 4WD warning light turns on when
you are driving on dry hard surface
roads:
– in the 4H position, shift the 4WD shift switch to 2WD.
– in the 4LO position, stop the vehicle, move the shift lever to the N position
with the brake pedal depressed, and
shift the 4WD shift switch to 2WD.
● If the warning light is still on after the
above operation, have your vehicle
checked by a NISSAN dealer as soon as
possible.
● The transfer case may be damaged if
you continue driving with the warning
light blinking.
INCREASING FUEL ECONOMYUSING 4-WHEEL DRIVE
(4WD) (if so equipped)
Starting and driving5-23

*1: The transfer 4LO position indicator light may blink. Stop the vehicle. Be sure to shift the 4WD shift switch after the shift lever has been moved to theN
position. If the indicator light keeps blinking after the 4WD shift procedure in the previous page, drive slowly without abrupt maneuvers for a while. Then the
light will turn on or off.
• Avoid making a turn or abrupt starts while shifting to 4LO. Otherwise gears may grind, damaging the drive system.
*2: While changing in and out of 4LO, the ignition switch must be ON and the vehicle’s engine must be running for a shift to take place and for the indicator
lights (4WD shift and 4LO position indicator) to be operable. Otherwise, the shift will not take place and no indicator lights will be on or flashing.
*3: Make sure the transfer 4LO position indicator light turns on when you shift the 4WD shift switch to 4LO. The
indicator light will also turn on when
4LO is selected. For additional information, refer to “Vehicle Dynamic Control (VDC) system” in this section.
The transfer case 4WD shift switch is used to select either 2WD or 4WD depending on the driving conditions. There are four types of drive modes available,
AUTO, 2WD, 4H and 4LO.
Starting and driving5-25

The 4WD shift switch electronically controls the
transfer case operation. Rotate the switch to
move between each mode, 2WD, AUTO, 4H and
4LO.
You must push the switch in to select 4LO,
and the vehicle MUST be stationary and the
shift lever in the N position when changing
into or out of 4LO.
WARNING
When parking, apply the parking brake
before stopping the engine and make sure
that the 4WD shift indicator light is on and
the ATP warning light goes off. Otherwise,
the vehicle could unexpectedly move even
if the automatic transmission is in the P
position.
CAUTION
●Never shift the 4WD shift switch be-
tween 4LO and 4H while driving.
● The 4H position provides greater trac-
tion. Avoid excessive speed, as it will
cause increased fuel consumption and
higher oil temperatures, and could
damage drivetrain components, Speeds
over 62 MPH (100 km/h) in 4H is not
recommended. ●
The 4LO position provides maximum
power and traction. Avoid raising vehicle
speed excessively, as the maximum speed
is approximately 31 MPH (50 km/h).
● When driving straight, shift the 4WD
shift switch to the 2WD, AUTO or 4H
position. Do not move the 4WD shift
switch when making a turn or reversing.
●
Do not shift the 4WD shift switch (be-
tween 2WD, AUTO and 4H) while driving
on steep downhill grades. Use the engine
brake and low automatic transmission
gears (D1 or D2) for engine braking.
● Do not operate the 4WD shift switch
(between 2WD, AUTO and 4H) with the
rear wheels spinning.
●
Do not drive on dry hard surface roads in
the 4H or 4LO position. Driving on dry
hard surfaces in 4H or 4LO may cause
unnecessary noise and tire wear. NISSAN
recommends driving in the 2WD or AUTO
position under these conditions.
●The 4WD transfer case may not be shifted
between 4H and 4LO at low ambient tem-
peratures and the transfer 4LO position
indicator light may blink even when the
4WD shift switch is shifted. After driving
for a while you can change the 4WD
transfer case between 4H and 4LO.
When driving on rough roads,
● Set the 4WD shift switch to AUTO, 4H or
4LO.
● Drive carefully according to the road surface
conditions.
When the vehicle is stuck, ● Set the 4WD shift switch to 4H or 4LO.
● If it is difficult to free the vehicle, repeat
forward and backward movement to in-
crease the movement.
● If the vehicle is stuck deep in mud, place
stones or wooden blocks under the tires.
Then try the recovery procedures above. Tire
chains may be effective.
CAUTION
● Do not spin the tires excessively. Tires
will sink deep into the mud, making it
difficult to free the vehicle.
● Avoid shifting gears with the engine
running at high speeds as this may
cause malfunction.
5-26Starting and driving

4WD shift switch operations
●Shift the 4WD shift switch to either the
2WD, AUTO, 4H or 4LO position, depend-
ing on driving conditions.
● With the switch set to the AUTO position,
distribution of torque to the front and rear
wheels changes automatically, depending
on road conditions encountered [ratio; 0 :
100 (2WD) →50 : 50 (4WD)]. This results
in improved driving stability. ●
If the 4WD shift switch is operated
while making a turn, accelerating or
decelerating or if the ignition switch is
turned off while in the AUTO, 4H or
4LO, you may feel a jolt. This is not
abnormal.
● When the vehicle is stopped after mak-
ing a turn, you may feel a slight jolt
after the shift lever is shifted to N or P.
This occurs because the transfer clutch
is released and not because of a mal-
function.
CAUTION
● When driving straight, shift the 4WD
shift switch to the 2WD, AUTO or 4H
position. Do not move the 4WD shift
switch when making a turn or reversing.
● Do not shift the 4WD shift switch while
driving on steep downhill grades. Use
the engine brake and low automatic
transmission gears (D1 or D2) for en-
gine braking.
● Do not operate the 4WD shift switch
with the rear wheels spinning. ●
Before placing the 4WD shift switch in
the 4H position from 2WD or AUTO,
ensure the vehicle speed is less than
62 MPH (100 km/h). Failure to do so can
damage the 4WD system.
● Never shift the 4WD shift switch be-
tween 4LO and 4H while driving.
● Engine idling speed is high while warm-
ing up the engine. Be especially careful
when starting or driving on slippery sur-
faces with the 4WD shift switch set in
AUTO.
