2008 NISSAN XTERRA check engine light

The 4WD shift indicator light is located in the
odometer display.
The light should turn off within 1 second after
turning the ignition switch to the ON position.
While the engine is running, the 4WD shift indi-
cator light will illuminate the position selected by
the 4WD shift switch.
cThe 4WD shift indicator light may blink
while shifting from one drive mode to
the other. When the shifting is com-
pleted, the 4WD shift indicator light
will come on.cIf the 4WD warning light comes on, the
4WD indicator light goes out.
CAUTION
If the 4WD shift indicator light indication
changes to 2WD when the 4WD shift
switch is shifted to the 4H position at low
ambient temperatures, the 2WD mode
may be being engaged due to malfunc-
tioning 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.

The 4WD warning light is located in the meter.
The 4WD warning light comes on when the key
switch is turned to ON. It turns off soon after the
engine is started.
If any malfunction occurs in the 4WD system
when the key 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.
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.

pedal. 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 (if so equipped) 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.When accelerating or driving on slippery sur-
faces, the tires may spin or slide. With the Vehicle
Dynamic Control (VDC) system, sensors detect
these movements and control the braking and
engine output to help improve vehicle stability.
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 are 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, most VDC functions will be turned off.
The VDC system will still try to transfer power
from a slipping drive wheel to one with more
traction when the VDC system switch is OFF. The
SLIPindicator 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, you
may 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 improve driving stabil-
ity but does not prevent accidents due
to abrupt steering operation at high
speeds or by careless or dangerous
driving techniques. Reduce vehicle
speed and be especially careful when
driving and cornering on slippery sur-
faces 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.
cDo not modify the vehicle’s suspension.
If suspension parts such as shock ab-
sorbers, struts, springs, stabilizer bars,bushings and wheels are not NISSAN
approved for your vehicle or are ex-
tremely deteriorated the Vehicle Dy-
namic Control system may not operate
properly. This could adversely affect ve-
hicle handling performance, and the
VDC OFF indicator light may come on.
cWhen driving on extremely inclined sur-
faces such as higher banked corners,
the Vehicle Dynamic Control system
may not operate properly and the VDC
OFF indicator light may come on. Do
not drive on these types of roads.
cWhen driving on an unstable surface
such as a turntable, ferry, elevator or
ramp, the Vehicle Dynamic Control off
indicator light may illuminate. This is
not a malfunction. Restart the engine
after driving onto a stable surface.
cIf wheels or tires other than the recom-
mended ones are used, the Vehicle Dy-
namic Control system may not operate
properly and the Vehicle Dynamic Con-
trol off indicator light may come on.
cThe Vehicle Dynamic Control system is
not a substitute for winter tires or tire
chains on a snow covered road.

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, 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. Shift the manual transmission into R
(Reverse) , or the automatic transmission
into 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 manual transmission is
shifted into R (Reverse) , or the auto-
matic transmission 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.

CAUTION
cDo not push start this vehicle. The
three-way catalyst may be damaged.
cAutomatic transmission models cannot
be push-started or tow-started. At-
tempting to do so may cause transmis-
sion damage.
cFor manual transmission models, never
try to start the vehicle by towing it.
When the engine starts, the forward
surge could cause the vehicle to collide
with the tow vehicle.
WARNING
cDo not continue to drive if your vehicle
overheats. Doing so could cause engine
damage or a vehicle fire.
cTo avoid the danger of being scalded,
never remove the radiator or coolant
reservoir cap while the engine is still
hot. When the radiator or coolant reser-
voir cap is removed, pressurized hot
water will spurt out, possibly causing
serious injury.
cDo not open the hood if steam is com-
ing out.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading and
the illumination of the engine oil pressure/engine
coolant temperature high indicator light) , or if you
feel a lack of engine power, detect abnormal
noise, etc. take the following steps.
1. Move the vehicle safely off the road, apply
the parking brake and move the shift lever to
P (Park) .
Do not stop the engine.
2. Turn off the air conditioner. Open all the
windows, move the heater or air conditioner
temperature control to maximum hot and fan
control to high speed.3. Get out of the vehicle. Look and listen for
steam or coolant escaping from the radiator
before opening the hood. (If steam or cool-
ant is escaping, turn off the engine.) Do not
open the hood further until no steam or
coolant can be seen.
4. Open the engine hood.
WARNING
If steam or water is coming from the en-
gine, stand clear to prevent getting
burned.
5. Visually check drive belts for damage or
looseness. Also check if the cooling fan is
running. The radiator hoses and radiator
should not leak water. If coolant is leaking,
the water pump belt is missing or loose, or
the cooling fan does not run, stop the en-
gine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or get caught in, engine belts or the
engine cooling fan. The engine cooling
fan can start at any time.

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 levels*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.

7. Refill engine with recommended oil through
the oil filler opening, then install the oil filler
cap securely.
See “Capacities and recommended
fuel/lubricants” in the “Technical and con-
sumer information” section of this manual for
drain and refill capacity.
The drain and refill capacity depends on the
oil temperature and drain time. Use these
specifications for reference only. Always use
the dipstick to determine when the proper
amount of oil is in the engine.
8. Start the engine. Check for leakage around
the drain plug and oil filter. Correct as re-
quired.
9. Turn the engine off and wait more than 10
minutes. Check the oil level with the dipstick.
Add engine oil if necessary.
CHANGING ENGINE OIL FILTER
1. Park the vehicle on a level surface and apply
the parking brake.
2. Turn the engine off.
3. Place a large drain pan under the oil filter.
4. Unscrew the plate covering the oil filter ex-
posing the filter.
5. Loosen the oil filter
sAwith an oil filter
wrench by turning it counterclockwise. Then
remove the oil filter by turning it by hand.
CAUTION
Be careful not to burn yourself. The engine
oil may be hot.
6. Wipe the engine oil filter sealing surface with
a clean rag.
CAUTION
Be sure to remove any old gasket material
remaining on the sealing surface of the
engine. Failure to do so could lead to
engine damage.
7. Coat the gasket on the new filter with clean
engine oil.
8. Screw on the oil filter until a slight resistance
is felt, then tighten an additional 2/3 turn.
9. Start the engine and check for leakage
around the oil filter. Correct as required.
