ENGINE OIL PRESSURE GAUGE
The gauge indicates the engine lubrication sys-
tem oil pressure while the engine is running. The
needle should be in the middle of the gauge when
the engine is running.
CAUTION
●This gauge is not designed to indicate
low engine oil level. Use the dipstick to
check the oil level. (See “Engine oil” in
the “Maintenance and do-it-yourself”
section.)
● If the gauge needle does not move with
the proper amount of engine oil, have
the vehicle checked by a NISSAN
dealer. Continued vehicle operation in
such a condition could cause serious
damage to the engine.
VOLTMETER
When the ignition switch is placed in the ON
position, the voltmeter indicates the battery volt-
age. When the engine is running, it indicates the
generator voltage.
While cranking the engine, the volts drop below
the normal range. If the needle is not in the normal
range (11 – 15 volts)
1while the engine is
running, it may indicate that the charging system
is not functioning properly. Have the system
checked by a NISSAN dealer.

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.
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

on steady if the fuel-filler cap is loose or missing,
or if the vehicle runs out of fuel. Check to make
sure the fuel-filler cap is installed and closed
tightly, and that the vehicle has at least 3 gallons
(11.4 liters) of fuel in the fuel tank.
After a few driving trips, the
light should
turn off if no other potential emission control
system malfunction exists.
If this indicator light comes on steady for 20
seconds and then blinks for 10 seconds when
the engine is not running, it indicates that the
vehicle is not ready for an emission control sys-
tem inspection/maintenance test. See “Readi-
ness for inspection/maintenance (I/M) test” in the
“Technical and consumer information” section of
this manual.
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.
