Automatic Transmission
Park warning light
(
model)
WARNING
• If the 4WD mode indicator is off or the
ATP warning light is on, this indicates
that the automatic transmission P
(Park) position will not function and
could result in the vehicle moving un-
expectedly, causing serious personal
injury or property damage. Always
set the parking brake. For additional
information, see “Using 4–wheel
drive (4WD)” (P. 5-105).
Instruments and controls2-13

•If the ATP light is on, this indicates
that the automatic transmission P
(Park) position will not function and
the transfer case is in neutral.
• When parking, always make sure that
the 4WD shif t indicator light illumi-
nates and the parking brake is set.
Failure to engage the transfer posi-
tion in 2WD, 4H or 4LO could result in
the vehicle moving unexpectedly, re-
sulting in serious personal injury or
property damage.
• Shif t the 4WD switch into the 2WD, 4H
or 4LO position again to turn off the
ATP warning light when the shif t le-
ver is in the P position and the ATP
warning light is on. (Before shif ting
the 4WD switch into the 4LO position,
move the shif t lever to the N position
once, shif t the shif t lever into P again
and make sure the ATP warning light
is off.)
This light indicates that the automatic
transmission parking function is not en-
gaged. If the transfer control is not secured
in any drive position while the shif t lever is
in the P (Park) position, the transmission will
disengage and the drive wheels will not
lock.orBrake warning
light

position, the light comes on when the park-
ing brake is applied.

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 ap-
plied, stop the vehicle and perform the fol-
lowing:
1. Check the brake fluid level. Add brake fluid as necessary. For additional infor-
mation, see “Brake fluid” (P. 8-14).
2. If the brake fluid level is correct, have the warning system checked. It is recom-
mended that you visit a NISSAN dealer
for this service.

ing properly if the warning light is on.
Driving could be dangerous. If you
judge it to be safe, drive carefully to
the nearest service station for re-
pairs. Otherwise, have your vehicle
towed because driving it could be
dangerous.
• Pressing the brake pedal with the en-
gine stopped and/or a low brake
fluid level may increase your stop-
ping distance and braking will re-
quire greater pedal effort and 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. It is
recommended that you visit a
NISSAN dealer for this service.
Charge warning light
If this light comes on while the engine is
running, it may indicate the charging sys-
tem is not functioning properly. Turn the
engine off and check the generator belt. If
the belt is loose, broken, missing, or if the

light remains on, have the system checked.
It is recommended that you visit a NISSAN
dealer for this service.
CAUTION
• Do not ground electrical accessories
directly to the battery terminal. Do-
ing so will bypass the variable volt-
age control system (if so equipped)
and the vehicle battery may not
charge completely. For additional in-
formation, see “Variable voltage con-
trol system” (P. 8-19).
• Do not continue driving if the genera-
tor belt is loose, broken or missing.

when the engine is not running, it indicates
that the vehicle is not ready for an emission
control system inspection/maintenance
test. For additional information, see “Readi-

The MIL will come on in one of two ways:
• MIL on steady — An emission control sys-tem malfunction has been detected.

• MIL blinking — An engine misfire has been detected which may damage the emis-
sion control system. To reduce or avoid
emission control system damage:– do not drive at speeds above 45 mph (72 km/h).
– avoid hard acceleration or decelera- tion.
– avoid steep uphill grades.
– if possible, reduce the amount of cargo being hauled or towed.

steady. Have the vehicle inspected. It is rec-
ommended that you visit a NISSAN dealer for this service. You do not need to have
your vehicle towed to the dealer.

having the emission control system
checked and repaired as necessary
could lead to poor driveability, reduced
fuel economy, and possible damage to
the emission control system.
