2017 NISSAN ARMADA warning light

5-126Starting and driving
The 4WD shift switch is used to select the 4WD
mode depending on the driving conditions.
There are 3 types of drive modes available,
AUTO, 4HI and 4LO.
The 4WD shift switch electronically controls the
transfer case operation. Rotate the switch to
move between each mode, AUTO, 4H and 4L.
You must depress the 4WD shift switch to
select 4L, and the vehicle MUST be sta-
tionary and the shift lever in the N (Neutral)
position when changing into or out of 4L.
WARNING
.When parking, apply the parking
brake before stopping the engine
and make sure that the 4WD shift
indicator is on and the ATP warning
light turns off. Otherwise, the vehi-
cle could unexpectedly move even if
the automatic transmission is in the
P (Park) position.
. The 4LO and 4HI indicators must
stop blinking and the 4LO or 4HI
indicator must remain illuminated or
turn off before shifting the trans-
mission into gear. If the shift lever is
shifted from the N (Neutral) position
to any other gear while the 4LO and 4HI indicators are blinking alter-
nately, the vehicle may move unex-
pectedly.
CAUTION
.
Never shift the 4WD shift switch
between 4L and 4H while driving.
. The 4HI position provides greater
traction. Avoid excessive speed, as
it will cause increased fuel con-
sumption and higher oil tempera-
tures, and could damage drivetrain
component. Speeds over 62 MPH
(100 km/h) in 4HI is not recom-
mended.
. The 4LO position provides maxi-
mum 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 AUTO or 4H
position. Do not move the 4WD shift
switch when making a turn or rever-
sing. .
Do not shift the 4WD shift switch
(between AUTO and 4H) while driv-
ing on steep downhill grades. Use
the engine brake and low automatic
transmission gears for engine brak-
ing.
. Do not operate the 4WD shift switch
(between AUTO and 4H) with the
rear wheels spinning.
. Do not drive on dry hard surface
roads in the 4HI or 4LO position.
Driving on dry hard surfaces in 4HI
or 4LO may cause unnecessary
noise and tire wear. NISSAN recom-
mends driving in the AUTO position
under these conditions.
. The 4WD transfer case may not be
shifted between 4HI and 4LO at low
ambient temperatures and the 4LO
and 4HI indicators may blink even
when the 4WD shift switch is
shifted. After driving for a while
you can change the 4WD shift
switch between 4H and 4L.

5-128Starting and driving
.Never shift the 4WD shift switch
between 4L and 4H while driving.
. Engine idling speed is high while
warming up the engine. Be espe-
cially careful when starting or driv-
ing on slippery surfaces with the
4WD shift switch in AUTO.

4WD SHIFT INDICATOR
The 4WD shift indicator is displayed in the
vehicle information display.
The indicator should turn off within 1 second
after placing the ignition switch in the ON
position.
While the engine is running, the 4WD shift
indicator will illuminate the position selected by
the 4WD shift switch. (See the 4WD shift
procedure list shown in the “NISSAN all-mode
4WD
Šsystem” (P.5-123) .)
. The 4WD shift indicator may blink while
shifting from one drive mode to the
other. When the shifting is completed, the 4WD shift indicator will come on. If
the indicator does not come on imme-
diately, make sure the area around the
vehicle is safe, and drive the vehicle
straight, accelerate or decelerate or
move the vehicle in reverse, then shift
the 4WD shift switch.
. If the 4WD warning light comes on, the
4WD shift indicator turns off.
4WD WARNING LIGHT
Warning light Comes on or
blinks when:
Illuminates There is a mal-
function in the 4WD system
Blinks rapidly The transfer case
oil temperature is abnormally high
Blinks slowly The difference in
wheel rotation is large
The 4WD warning light is located in the meter.
The 4WD warning light comes on when the
ignition switch is placed in the ON position. It
turns off soon after the engine is started.
If any malfunction occurs in the 4WD system
when the ignition switch is placed in the ON
position, the 4WD warning light will either
remain illuminated or blink.

If the 4WD warning light comes on, the 4WD
shift indicator turns off.
High-temperature transfer case oil makes the
4WD warning light blink rapidly (about twice per
second) . If the warning light blinks rapidly during
operation, stop the vehicle in a safe place
immediately. Then if the light turns off after a
while, you can continue driving.
A large difference between the diameters of
front and rear wheels will make the 4WD
warning light blink slowly (about once per two
seconds) . Change the 4WD shift switch to
AUTO and do not drive fast.
CAUTION
.If the 4WD warning light comes on
or blinks slowly during operation or
rapidly after stopping the vehicle for
a while, have your vehicle checked
as soon as possible. It is recom-
mended you visit a NISSAN dealer
for this service.
. Shifting between 4HI and 4LO is not
recommended when the 4WD warn-
ing light turns on.
. When the 4WD warning light comes
on, the 2WD mode may be engaged even if the 4WD shift switch is in
AUTO or 4H. Be especially careful
when driving. If corresponding parts
are malfunctioning, the 4WD mode
will not be engaged even if the 4WD
shift switch is shifted.
. Do not drive the vehicle in the 4HI or
4LO position on dry hard surface
roads. Driving on dry, hard surfaces
in 4HI or 4LO may cause unneces-
sary noise, tire wear and increased
fuel consumption.
If the 4WD warning light turns on
when driving on dry hard surface
roads:
— in the AUTO or 4HI position, shift
the 4WD shift switch to AUTO.
— in the 4LO position, stop the vehicle and shift the transmis-
sion shift lever to the N (Neutral)
position and shift the 4WD shift
switch to AUTO.
. If the 4WD warning light is still on
after the above operation, have your
vehicle checked as soon as possi-
ble. It is recommended you visit a
NISSAN dealer for this service. .
The transfer case may be damaged
if you continue driving with the
warning light blinking.

WARNING
.Never rely solely on the hill start
assist system to prevent the vehicle
from moving backward on a hill.
Always drive carefully and atten-
tively. Depress the brake pedal
when the vehicle is stopped on a
steep hill. Be especially careful
when stopped on a hill on frozen
or muddy roads. Failure to prevent
the vehicle from rolling backwards
may result in a loss of control of the
vehicle and possible serious injury
or death.
. The hill start assist system is not
designed to hold the vehicle at a
standstill on a hill. Depress the
brake pedal when the vehicle is
stopped on a steep hill. Failure to
do so may cause the vehicle to roll
backwards and may result in a
collision or serious personal injury.
. The hill start assist system may not
prevent the vehicle from rolling
backwards on a hill under all load
or road conditions. Always be pre-
pared to depress the brake pedal to prevent the vehicle from rolling
backwards. Failure to do so may
result in a collision or serious per-
sonal injury.
The hill start assist system automatically keeps
the brakes applied to help prevent the vehicle
from rolling backwards in the time it takes the
driver to release the brake pedal and apply the
accelerator when the vehicle is stopped on a hill.
The hill start assist system will operate auto-
matically under the following conditions:
. The transmission is shifted to a forward or
reverse gear.
. The vehicle is stopped completely on a hill
by applying the brake.
The maximum holding time is 2 seconds. After 2
seconds the vehicle will begin to roll back and
the hill start assist system will stop operating
completely.
The hill start assist system will not operate when
the transmission is shifted to the N (Neutral) or P
(Park) position or on a flat and level road.
When the Vehicle Dynamic Control (VDC)
warning light illuminates in the meter, the hill
start assist system will not operate. (See
“Warning lights, indicator lights and audible
reminders” (P.2-10).)

SONAR SYSTEM OFF SWITCH
The sonar system OFF switch on the lower side
of the instrument panel allows the driver to turn
the sonar system on and off. To turn the sonar
system on and off, the ignition switch must be in
the ON position. The indicator light
*1on the
switch will illuminate when the system is turned
off. If the indicator light flashes when the sonar
system is not turned off, it may indicate a
malfunction in the sonar system.
The sonar system will turn on automatically
under the following conditions.
. When the ignition switch is turned from the
OFF position to the ON position. .
When the shift lever is in the R (Reverse)
position.
. When the vehicle speed is less than 6 MPH
(10 km/h) .
The automatic turning on function can be turned
on and off by pushing the switch for more than 4
seconds.
WARNING
If the engine is not running or is turned
off while driving, the power assist for
the steering will not work. Steering will
be harder to operate.
The power assisted steering uses a hydraulic
pump, driven by the engine, to assist steering.
If the engine stops or the drive belt breaks, you
will still have control of the vehicle. However,
much greater steering effort is needed, espe-
cially in sharp turns and at low speeds.

POWER STEERING

5-136Starting and driving
BRAKING PRECAUTIONS
The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking ability at two wheels.
You may feel a small click and hear a sound
when the brake pedal is fully depressed slowly.
This is not a malfunction and indicates that the
brake assist mechanism is operating properly.
Hydraulically-assisted brakes
The hydraulically-assisted brake system is de-
signed to use a hydraulic pump driven electri-
cally, to assist braking. If the engine stops, you
can stop the vehicle by depressing the foot
brake pedal. However, greater foot pressure on
the foot brake pedal will be required to stop the
vehicle. The stopping distance will be longer.
Wet brakes
When the vehicle is washed or driven through
water, the brakes may get wet. As a result, your
braking distance will be longer and the vehicle
may pull to one side during braking.
To dry brakes, drive the vehicle at a safe speed
while lightly tapping the brake pedal to heat-up
the brakes. Do this until the brakes return to
normal. Avoid driving the vehicle at high speeds
until the brakes function correctly.
PARKING BRAKE BREAK-IN
Break in the parking brake shoes whenever the
stopping effect of the parking brake is weakened
or whenever the parking brake shoes and/or
drums/rotors are replaced, in order to assure the
best braking performance.
This procedure is described in the vehicle
service manual. It is recommended you visit a
NISSAN dealer for this service.
Using the brakes
Avoid resting your foot on the brake pedal while
driving. This will cause overheating of the
brakes, wearing out the brake and pads faster
and reduce gas mileage.
To help save the brakes and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going down a
slope or long grade. Overheated brakes may
reduce braking performance and could result in
loss of vehicle control.
WARNING
.While driving on a slippery surface,
be careful when braking, accelerat-
ing or downshifting. Abrupt braking
or accelerating could cause the
wheels to skid and result in an accident.
. If the engine is not running or is
turned off while driving, the power
assist for the brakes will not work.
Braking will be harder.
BRAKE SYSTEM

BRAKE ASSIST
When the force applied to the brake pedal
exceeds a certain level, the Brake Assist is
activated generating greater braking force than a
conventional brake booster even with light pedal
force.
WARNING
The Brake Assist is only an aid to assist
braking operation and is not a collision
warning or avoidance device. It is the
driver’s responsibility to stay alert, drive
safely and be in control of the vehicle at
all times.
ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
.The Anti-lock Braking System (ABS)
is a sophisticated device, but it
cannot prevent accidents resulting
from careless or dangerous driving
techniques. It can help maintain
vehicle control during braking on
slippery surfaces. Remember that
stopping distances on slippery sur-
faces will be longer than on normal surfaces even with ABS. Stopping
distances may also be longer on
rough, gravel or snow covered
roads, or if you are using tire chains.
Always maintain a safe distance
from the vehicle in front of you.
Ultimately, the driver is responsible
for safety.
. Tire type and condition may also
affect braking effectiveness.
— When replacing tires, install the
specified size of tires on all four
wheels.
— When installing a spare tire, make sure that it is the proper
size and type as specified on the
Tire and Loading Information
label. See “Tire and loading
information label” (P.10-12) .
— For detailed information, see “Wheels and tires” (P.8-30) .
The Anti-lock Braking System (ABS) controls
the brakes so the wheels do not lock during hard
braking or when braking on slippery surfaces.
The system detects the rotation speed at each
wheel and varies the brake fluid pressure to
prevent each wheel from locking and sliding. By preventing each wheel from locking, the system
helps the driver maintain steering control and
helps to minimize swerving and spinning on
slippery surfaces.
Using the system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The
ABS will operate to prevent the wheels from
locking up. Steer the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping dis-
tances.
Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer. The
computer has a built-in diagnostic feature that
tests the system each time you start the engine
and move the vehicle at a low speed in forward
or reverse. When the self-test occurs, you may
hear a “clunk” noise and/or feel a pulsation in the
brake pedal. This is normal and does not
indicate a malfunction. If the computer senses
a malfunction, it switches the ABS off and
Starting and driving5-137
BRAKE ASSIST

5-138Starting and driving
illuminates the ABS warning light on the
instrument panel. The brake system then oper-
ates normally, but without anti-lock assistance.
If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked. It is recommended you visit a NISSAN
dealer for this service.
Normal operation
The ABS operates at speeds above 3 to 6 MPH
(5 to 10 km/h) . The speed varies according to
road conditions.
When the ABS senses that one or more wheels
are close to locking up, the actuator rapidly
applies and releases hydraulic pressure. This
action is similar to pumping the brakes very
quickly. You may feel a pulsation in the brake
pedal and hear a noise from under the hood or
feel a vibration from the actuator when it is
operating. This is normal and indicates that the
ABS is operating properly. However, the pulsa-
tion may indicate that road conditions are
hazardous and extra care is required while
driving.The Vehicle Dynamic Control (VDC) system
uses various sensors to monitor driver inputs
and vehicle motion. Under certain driving con-
ditions, the VDC system helps to perform the
following functions.
.
Controls brake pressure to reduce wheel
slip on one slipping drive wheel so power is
transferred to a non slipping drive wheel on
the same axle.
. Controls brake pressure and engine output
to reduce drive wheel slip based on vehicle
speed (traction control function) .
. Controls brake pressure at individual wheels
and engine output to help the driver maintain
control of the vehicle in the following
conditions:
— understeer (vehicle tends to not follow
the steered path despite increased
steering input)
— oversteer (vehicle tends to spin due to certain road or driving conditions) .
The VDC system can help the driver to maintain
control of the vehicle, but it cannot prevent loss
of vehicle control in all driving situations.
When the VDC system operates, the VDC
warning light
in the instrument panel flashes
so note the following:
. The road may be slippery or the system may
determine some action is required to help keep the vehicle on the steered path.
. You may feel a pulsation in the brake pedal
and hear a noise or vibration from under the
hood. This is normal and indicates that the
VDC system is working properly.
. Adjust your speed and driving to the road
conditions.
If a malfunction occurs in the system, the VDC
warning light
illuminates in the instrument
panel. The VDC system automatically turns off.
The VDC OFF switch is used to turn off the VDC
system. The VDC off indicator
illuminates to
indicate the VDC system is off. When the VDC
switch is used to turn off the system, the VDC
system still operates to prevent one drive wheel
from slipping by transferring power to a non
slipping drive wheel. The VDC warning light
flashes if this occurs. All other VDC functions
are off, and the VDC warning lightwill not
flash. The VDC system is automatically reset to
on when the ignition switch is placed in the OFF
position then back to the ON position.
When the 4L position is selected with the 4WD
shift switch, the VDC system is disabled and the
VDC off indicator light illuminates (for 4WD
models) .
See “Vehicle Dynamic Control (VDC) warning
light” (P.2-17) and “Vehicle Dynamic Control
(VDC) off indicator light” (P.2-20).
