2009 NISSAN PATHFINDER check engine light

cIf the 4WD shift indicator light indica-
tion changes to 2WD when the 4WD
shift switch is shifted to the AUTO or 4H
position at low ambient temperatures,
the 2WD mode may be being engaged
due to malfunctioning drive system. If
the indicator does not return to normal
and the 4WD warning light comes on,
have the system checked by the nearest
NISSAN dealer.
4WD warning light
Warning lightComes on or blinks
when:
Comes onThere is a malfunc-
tion in the 4–wheel
drive system
Blinks rapidlyThe transfer case
oil temperature is
abnormally high (all
mode 4WD ve-
hicles)
Blinks slowlyThe difference in
wheel rotation is
large
The 4WD warning light is located in the meter.
The 4WD warning light comes on when the igni-
tion switch is turned to ON. It turns off soon after
the engine is started.
If any malfunction occurs in the 4WD system
when the ignition switch is ON, the warning light
will either remain illuminated or blink.
If the 4WD warning light comes on, the 4WD
shift indicator light goes out.
For all mode 4WD vehicles, high-temperature
transfer case oil makes the warning light blink
rapidly (about twice per second) . If the warning
light blinks rapidly during operation, stop the ve-
hicle in a safe place immediately. Then if the light
goes off after a while, you can continue driving.
A large difference between the diameters of front
and rear wheels will make the warning light blink
slowly (about once per two seconds) . Change
the 4WD shift switch into 2WD and do not drive
fast.
CAUTION
cIf the warning light comes on or blinks
slowly during operation or rapidly after
stopping the vehicle for a while, have
your vehicle checked by a NISSAN
dealer as soon as possible.cShifting between 4H and 4LO is not
recommended when the 4WD warning
light turns on.
cWhen the 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 corre-
sponding parts are malfunctioning, the
4WD mode will not be engaged even if
the 4WD shift switch is shifted.
cDo 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 AUTO or 4H position, shift the
4WD shift switch to 2WD.
– in the 4LO position for all mode 4WD
vehicles, stop the vehicle and shift
the transmission selector to the N
position and shift the 4WD shift
switch to 2WD.

cIf the warning light is still on after the
above operation, have your vehicle
checked by a NISSAN dealer as soon as
possible.
cThe transfer case may be damaged if
you continue driving with the warning
light blinking rapidly.
WARNING
cDo not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite
and cause a fire.
cSafe parking procedures require that
both the parking brake be set and the
transmission placed into P (Park) . Fail-
ure to do so could cause the vehicle to
move unexpectedly or roll away and re-
sult in an accident. Make sure the shift
lever has been pushed as far forward as
it can go and cannot be moved without
depressing the foot brake pedal.cNever leave the engine running while
the vehicle is unattended.
cDo not leave children unattended inside
the vehicle. They could unknowingly ac-
tivate switches or controls. Unattended
children could become involved in seri-
ous accidents.
1. Firmly apply the parking brake.
2. Move the shift selector to the P (Park)
position.
3. To help prevent the vehicle from rolling into
traffic when parked on an incline, it is a good
practice to turn the wheels as illustrated.

WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping
distances.
Normal operation
The ABS operates at speeds above3-6MPH(5
- 10 km/h) .
When the ABS senses that one or more wheels
are close to locking up, the system electronically
controls the pressure applied to each brake.
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 oper-
ating. This is normal and indicates that the ABS is
operating properly. However, the pulsation may
indicate that road conditions are hazardous and
extra care is required while driving.
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 brakepedal. This is normal and does not indicate a
malfunction. If the computer senses a malfunc-
tion, it switches the ABS off and illuminates the
ABS warning light on the instrument panel. The
brake system then operates normally, but without
anti-lock assistance.
If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked by a NISSAN dealer.cABLS is a form of traction control using
sensors from the Anti-lock Brake System
(ABS) to transfer power from a slipping drive
wheel to a wheel with more traction. The
ABLS system applies braking to the slipping
wheel, which helps redirect power to an-
other wheel.
cOn 4WD models the ABLS system operates
in both 4H and 4LO modes. If 4WD mode is
engaged, the ABLS system will operate for
both drive axles. On 2WD vehicles, the
ABLS system operates on the drive axle
only.
cThe ABLS system is always ON unless the
system detects brake pad overheating. If
high brake pad temperature is detected, it
will turn OFF, but normal brake function will
continue. ABLS will function even when the
VDC system is turned OFF.
WARNING
The ABLS system provides increased trac-
tion, but will not prevent accidents due to
abrupt steering operation or by careless
driving or dangerous driving practices.
Reduce vehicle speed and be especially
careful when driving and cornering on
slippery surfaces, and always drive
carefully.

The Vehicle Dynamic Control (VDC) system uses
various sensors to monitor driver inputs and ve-
hicle motion. Under certain driving situations, the
system will control braking and engine output to
help keep the vehicle on its steered path.
cWhen the Vehicle Dynamic Control (VDC)
system is operating, theSLIPindicator in
the instrument panel blinks.
cIf the 4WD transfer case is shifted into 4LO
the
indicator light will come on and
the VDC system will be turned off. See
“Transfer case shifting procedures” earlier in
this section.
cIf the SLIP indicator blinks, the road condi-
tions may be slippery. Be sure to adjust your
speed and driving to these conditions. See
“Slip indicator light”, and “Vehicle Dynamic
Control (VDC) off indicator light” in the “In-
struments and controls” section.
If the battery is removed or discharged, the Trac-
tion Control System may be disabled and the
SLIPand
indicator lights will not turn off
after 2 seconds when the ignition switch is turned
to the ON position.
Perform the following procedure to reset the
system:
cStart the engine and set the steering wheel
in the straight forward position.cDrive the vehicle at speeds above 10 mph
(15 km/h) for at least 10 minutes.
cThe VDC OFF indicator light should go off
indicating the traction control system is op-
erational.
cIf you interrupt the reset procedure by turn-
ing the ignition off, you will need to restart
the reset procedure.
If after driving the vehicle for more than 10 min-
utes and theSLIPand
lights remain illumi-
nated in the instrument panel, have the vehicle
dynamic control system checked by a NISSAN
dealer.
If the vehicle is operated with the Vehicle Dy-
namic Control system off using the VDC OFF
switch, VDC and Traction Control System (TCS)
functions will be turned off. TheSLIPindicator
will flash if wheel spin is detected. The ABS will
still operate with the VDC system off.
When the VDC system is operating, 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 prop-
erly.
The computer has a built in diagnostic feature
that tests the system each time you start the
engine and move the vehicle forward or in reverse
at a slow speed. When the self-test occurs, youmay hear a clunk noise and/or feel a pulsation in
the brake pedal. This is normal and is not an
indication of a malfunction.
WARNING
cThe Vehicle Dynamic Control system is
designed to help maintain traction with
the road service but does not prevent
accidents due to abrupt steering opera-
tion at high speeds or by careless or
dangerous driving techniques. Reduce
vehicle speed and be especially careful
when driving and cornering on slippery
surfaces and always drive carefully.
cIf brake related parts such as brake
pads, rotors and calipers are not stan-
dard equipment or are extremely dete-
riorated, the Vehicle Dynamic Control
system may not operate properly and
the Vehicle Dynamic Control off indica-
tor light may come on.

WARNING
cIf the low tire pressure warning light
illuminates while driving, avoid sudden
steering maneuvers or abrupt braking,
reduce vehicle speed, pull off the road
to a safe location and stop the vehicle
as soon as possible. Driving with under-
inflated tires may permanently damage
the tires and increase the likelihood of
tire failure. Serious vehicle damage
could occur and may lead to an acci-
dent and could result in serious per-
sonal injury. Check the tire pressure for
all four tires. Adjust the tire pressure to
the recommended COLD tire pressure
shown on the Tire and Loading Informa-
tion label to turn the low tire pressure
warning light OFF. If you have a flat tire,
replace it with a spare tire as soon as
possible.
cWhen a spare tire is mounted or a wheel
is replaced, tire pressure will not be
indicated, the TPMS will not function
and the low tire pressure warning light
will flash for approximately 1 minute.
The light will remain on after 1 minute.
Contact your NISSAN dealer as soon as
possible for tire replacement and/or
system resetting.cReplacing tires with those not originally
specified by NISSAN could affect the
proper operation of the TPMS.
cDo not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pressure
sensors.
CHANGING A FLAT TIRE
If you have a flat tire, follow the instructions be-
low.
Stopping the vehicle
1. Safely move the vehicle off the road and
away from traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the parking
brake. Move the shift selector to P (Park) .
4. Turn off the engine.
5. Raise the hood to warn other traffic and to
signal professional road assistance person-
nel that you need assistance.
6. Have all passengers get out of the vehicle
and stand in a safe place, away from traffic
and clear of the vehicle.
WARNING
cMake sure the parking brake is securely
applied and the automatic transmission
is shifted into P (Park) .
cNever change tires when the vehicle is
on a slope, ice or slippery areas. This is
hazardous.
cNever change tires if oncoming traffic is
close to your vehicle. Wait for profes-
sional road assistance.

Steering wheelCheck for changes in the steer-
ing system, such as excessive freeplay, hard
steering or strange noises.
Warning lights and chimesMake sure all
warning lights and chimes are operating properly.
Windshield wiper and washer*Check that
the wipers and washer operate properly and that
the wipers do not streak.
Windshield defrosterCheck that the air
comes out of the defroster outlets properly and in
sufficient quantity when operating the heater or
air conditioner.
Under the hood and vehicle
The maintenance items listed here should be
checked periodically (for example, each time you
check the engine oil or refuel) .
Battery*Check the fluid level in each cell. It
should be between the MAX and MIN lines. Ve-
hicles operated in high temperatures or under
severe conditions require frequent checks of the
battery fluid level.
Brake fluid level*Make sure that the brake fluid
level is between the MIN and MAX lines on the
reservoir.
Engine coolant level*Check the coolant level
when the engine is cold.Engine drive belts*Make sure the drive belts
are not frayed, worn, cracked or oily.
Engine oil level*Check the level after parking
the vehicle on a level surface with the engine off.
Wait more than 10 minutes for the oil to drain
back into the oil pan.
Exhaust systemMake sure there are no loose
supports, cracks or holes. If the sound of the
exhaust seems unusual or there is a smell of
exhaust fumes, immediately have the exhaust
system inspected by a NISSAN dealer. See the
carbon monoxide warning in the “Starting and
driving” section of this manual.
Fluid leaksCheck under the vehicle for fuel, oil,
water or other fluid leaks after the vehicle has
been parked for a while. Water dripping from the
air conditioner after use is normal. If you should
notice any leaks or if gasoline fumes are evident,
check for the cause and have it corrected imme-
diately.
Power steering fluid level* and linesCheck
the level when the fluid is cold, with the engine
off. Check the lines for proper attachment, leaks,
cracks, etc.
Radiator and hosesCheck the front of the
radiator and clean off any dirt, insects, leaves,etc., that may have accumulated. Make sure the
hoses have no cracks, deformation, rot or loose
connections.
UnderbodyThe underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances from the
underbody, otherwise rust may form on the floor
pan, frame, fuel lines and exhaust system. At the
end of winter, the underbody should be thor-
oughly flushed with plain water, in those areas
where mud and dirt may have accumulated. See
the “Appearance and care” section of this
manual.
Windshield washer fluid*Check that there is
adequate fluid in the reservoir.
