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 park
warning light (
model)
This light indicates that the automatic transmis-
sion parking function is not engaged. If the trans-
fer control shift lever is not secured in any drive

4H, or 4L position when the warning light comes
on.
cWhen parking, always make sure that the
transfer control shift lever is in 2H, 4H, or 4L
and the parking brake is set.
cIf the ATP light is ON, this indicates that the
automatic transmission P (Park) position will
not function and the transfer control shift
lever is in the N (Neutral) position.
cFailure to engage the transfer shift control
lever in 2H, 4H or 4L could result in the
vehicle moving unexpectedly, resulting in se-
rious personal injury or property damage.

the automatic transmission P (Park) posi-
tion will not function and the transfer con-
trol shift lever is in the N (Neutral)
position.

2. If the brake fluid level is correct, have the
brake system checked by a NISSAN dealer.
WARNING
cYour 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.
cPressing 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.
cIf 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.

the door, the system may not arm. Fur-
thermore, if the key is turned exces-
sively to the unlock position, the sys-
tem may be disarmed when the key is
removed. If the indicator light fails to
glow for 30 seconds, unlock the door
once and lock it again.

50 seconds. However, the alarm reactivates
if the vehicle is tampered with again. The
alarm can be shut off by unlocking a door
with the key, or by pressing the
button
on the keyfob.
The alarm is activated by:
copening a door without using the key or
keyfob (even if the door is unlocked by re-
leasing the inside lock knob) .
copening the hood.
How to stop an activated alarm
The alarm stops only by unlocking a door with the
key or by pressing thebutton on the key-
fob.
