off:
or,,,,,,
,,
If any light fails to come on, it may indicate
an open circuit in the electrical system.
Have the system repaired promptly.
WARNING LIGHTS
orAnti-lock BrakingSystem (ABS)
warning light
When the ignition switch is placed in the ON
position, the Anti-lock Braking System (ABS)
warning light illuminates and then turns off. This
indicates the ABS is operational. If the ABS warning light illuminates while the
engine is running, or while driving, it may indicate
the ABS is not functioning properly. Have the
system checked by a NISSAN dealer.
If an ABS malfunction occurs, the anti-lock func-
tion is turned off. The brake system then operates
normally, but without anti-lock assistance. See
“Brake system” in the “Starting and driving” sec-
tion.
Automatic Transmission check
warning light
When the ignition switch is placed in the ON
position, the light comes on for about 2 seconds.
If the light comes on at any other time, it may
indicate the automatic transmission system is not
functioning properly. Have the system checked
by a NISSAN dealer.
Automatic transmission oiltemperature warning light (if so
equipped)
This light comes on when the automatic transmis-
sion oil temperature is too high. If the light comes
on while driving, reduce the vehicle speed as
soon as safely possible until the light turns off.
CAUTION
Continued vehicle operation when the A/T
oil temperature warning light is on may
damage the automatic transmission.
Automatic transmission parkwarning light (
model)
WARNING
● If the ATP light is ON, this indicates that
the automatic transmission P (Park) po-
sition will not function and the transfer
case is in neutral.
● When parking, always make sure that
the 4WD shift indicator light illuminates
and the parking brake is set. Failure to
engage the transfer position in 2WD, 4H
or 4LO could result in the vehicle mov-
ing unexpectedly, resulting in serious
personal injury or property damage.
Instruments and controls2-15

●Shift the 4WD switch into the 2WD, 4H
or 4LO position again to turn off the ATP
warning light when the shift selector is
in the P position and the ATP warning
light is ON. (Before shifting the 4WD
switch into the 4LO position, move the
shift selector into the N position once,
shift the shift selector into P again and
make sure the ATP warning light is
OFF.)
This light indicates that the automatic transmis-
sion parking function is not engaged. If the trans-
fer control is not secured in any drive position
while the shift selector is in the P (Park) position,
the transmission will disengage and the drive
wheels will not lock.
orBrake warning light
This light functions for both the parking brake and
the foot brake systems.
Parking brake indicator
When the ignition switch is placed in the ON
position, the light comes on when the parking
brake is applied.
Low brake fluid warning light
When the ignition switch is placed in the ON
position, the light warns of a low brake fluid level. If the light comes on while the engine is running
with the parking brake not applied, stop the ve-
hicle and perform the following:
1. Check the brake fluid level. Add brake fluid as necessary. See “Brake fluid” in the “Main-
tenance and do-it-yourself” section of this
manual.
2. If the brake fluid level is correct, have the warning system checked by a NISSAN
dealer.
WARNING
●Your brake system may not be working
properly if the warning light is on. Driv-
ing could be dangerous. If you judge it
to be safe, drive carefully to the nearest
service station for repairs. Otherwise,
have your vehicle towed because driv-
ing it could be dangerous.
● Pressing the brake pedal with the en-
gine stopped and/or a low brake fluid
level may increase your stopping dis-
tance and braking will require greater
pedal effort as well as pedal travel. ●
If the brake fluid level is below the
MINIMUM or MIN mark on the brake
fluid reservoir, do not drive until the
brake system has been checked at a
NISSAN dealer.
Anti-lock Braking System (ABS) warning
indicator
When the parking brake is released and the
brake fluid level is sufficient, if both the brake
warning light and the Anti-lock Braking System
(ABS) warning light illuminate, it may indicate the
ABS is not functioning properly. Have the brake
system checked, and if necessary, repaired by a
NISSAN dealer promptly. Avoid high-speed driv-
ing and abrupt braking. (See “Anti-lock Braking
System (ABS) warning light” in this section.)
Charge warning light
If this light comes on while the engine is running,
it may indicate the charging system is not func-
tioning properly. Turn the engine off and check
the generator belt. If the belt is loose, broken,
missing, or if the light remains on, see a NISSAN
dealer immediately.
2-16Instruments and controls

CAUTION
●Do not ground electrical accessories
directly to the battery terminal. Doing
so will bypass the variable control sys-
tem and the vehicle battery may not
charge completely. Refer to “Variable
voltage control system” in the “Mainte-
nance and do-it-yourself” section later
in this manual.
● Do not continue driving if the generator
belt is loose, broken or missing.
Door open warning light
This light comes on when any of the doors are not
closed securely while the ignition switch is in the
ON position.
Engine oil pressure warning
light
This light warns of low engine oil pressure. If the
light flickers or comes on during normal driving,
pull off the road in a safe area, stop the engine
immediately and call a NISSAN dealer or other
authorized repair shop. The engine oil pressure warning light is not
designed to indicate a low oil level.
Use the
dipstick to check the oil level. See “Engine oil” in
the “Maintenance and do-it-yourself” section 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.
4WD warning light (
model)
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 the engine or vehicle is not functioning properly,
the warning light will either remain illuminated or
blink. See “4WD warning light” in the “Starting
and driving” section.
CAUTION
● If the warning light comes on or blinks
during operation, have your vehicle
checked by a NISSAN dealer as soon as
possible.
● Do not drive on dry hard surface roads
in the 4H or 4LO position. 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 for automatic transmission models, stop the ve-
hicle and shift the shift selector to
the N (Neutral) position with the
brake pedal depressed and shift the
4WD shift switch to 2WD.
– in the 4LO position for manual trans- mission models, stop the vehicle and
shift the shift selector to the N (Neu-
tral) position with the clutch 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.
Instruments and controls2-17

Operation
The Malfunction Indicator Light will come on in
one of two ways:● Malfunction Indicator Light on steady — An
emission control system malfunction has
been detected. Check the fuel-filler cap if
the LOOSE FUEL CAP warning message is
displayed in the odometer. If the fuel-filler
cap is loose or missing, tighten or install the
cap and continue to drive the vehicle.
The
light should turn off after a few
driving trips. If the
light does not turn
off after a few driving trips, have the vehicle
inspected by a NISSAN dealer. You do not
need to have your vehicle towed to the
dealer.
● Malfunction Indicator Light blinking — An
engine misfire has been detected which may
damage the emission control system. To re-
duce or avoid emission control system dam-
age:
– do not drive at speeds above 45 MPH (72 km/h) .
– avoid hard acceleration or deceleration.
– avoid steep uphill grades.
– if possible, reduce the amount of cargo being hauled or towed. The Malfunction Indicator Light may stop blinking
and come on steady. Have the vehicle inspected
by a NISSAN dealer. You do not need to have
your vehicle towed to the dealer.
CAUTION
Continued vehicle operation without hav-
ing the emission control system checked
and repaired as necessary could lead to
poor driveability, reduced fuel economy,
and possible damage to the emission con-
trol system.
Overdrive off indicator light
(A/T models only)
This light comes on when the overdrive function
is OFF.
The automatic transmission overdrive function is
controlled by the overdrive switch.
See “Driving the vehicle” in the “Starting and
driving” section of this manual.
Security indicator light (if soequipped)
This light blinks when the ignition switch is in the
OFF, LOCK or ACC position. The blinking secu-
rity indicator light indicates that the security sys-
tems equipped on the vehicle are operational. For additional information, see “Security sys-
tems” later in this section.
Slip indicator light for models
with ABLS
This indicator light comes on if the active brake
limited slip is activated. If activated, the system
will apply braking to the slipping drive wheel(s) ,
giving the non-slipping wheel(s) more traction.
Slip indicator light for modelswith VDC
This indicator will blink when the VDC system or
the traction control system is operating, thus
alerting that the vehicle is nearing its traction
limits. The road surface may be slippery.
Transfer 4LO position indicatorlight (
model)
The light should turn off within 1 second after
turning the ignition switch to ON.
This light comes on when the 4WD shift switch is
set in the 4LO position with the ignition switch in
the ON position.
The transfer case may be damaged if you shift the
switch while driving.
