AUXILIARY GAUGES (if so
equipped)
1. Automatic Transmission fluid tempera-ture gauge
2. Voltmeter
3. Engine oil pressure gauge
4. Engine oil temperature gauge
Automatic Transmission fluid
temperature gauge
This gauge indicates the temperature of
the automatic transmission fluid.
CAUTION
• This gauge is not designed to indi-
cate low automatic transmission
fluid level. Use the dipstick to check
the fluid level. For additional infor-
mation, see “9–speed Automatic
Transmission Fluid (ATF)” (P. 8-13).
• If the gauge indicates automatic
transmission fluid temperature over
the normal range, stop the vehicle as
soon as safely possible. It is recom-
mended that you have the vehicle
checked by a NISSAN dealer. Contin-
ued operation of the vehicle may se-
riously damage the transmission.
Voltmeter
When the ignition switch is placed in the ON
position, the voltmeter indicates the bat-
tery voltage. When the engine is running, it
indicates the generator voltage.
While cranking the engine, the volts drop
below the normal range. If the range is not
within the normal range (11 – 15 volts) while
the engine is running, it may indicate that
the charging system is not functioning
properly. Have the system checked. It is
recommended that you visit a NISSAN
dealer for this service.
Engine oil pressure gauge
The gauge indicates the engine lubrication
system oil pressure while the engine is run-
ning. The bar should be in the middle of the
gauge when the engine is running.
CAUTION
• This gauge is not designed to indi-
cate low engine oil level. Use the dip-
stick to check the oil level. For addi-
tional information, see “Engine oil”
(P. 8-7).
• If the gauge needle does not move
with the proper amount of engine oil,
it is recommended that you have the
vehicle checked by a NISSAN dealer.
Continued vehicle operation in such
a condition could cause serious dam-
age to the engine.
Engine oil temperature gauge
This gauge measures the temperature of
the engine oil.

•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
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 park-
ing 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 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.
WARNING
• Your brake system may not be work-
ing properly if the warning light is on.

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.

AT (Automatic
Transmission) CHECK
If the service warning appears while the
engine is running, or while driving, it may
indicate that the AT is not functioning prop-
erly and may need servicing. Have the sys-
tem checked, and if necessary, repaired
promptly. It is recommended that you visit
a NISSAN dealer for this service.
AT (Automatic Transmission) Error:
See Owner’s Manual
If this message appears while the engine is
running, or while driving, it may indicate
that the AT is not functioning properly and
may need servicing. Have the system
checked, and if necessary, repaired
promptly. It is recommended that you visit
a NISSAN dealer for this service.
Service AT
This transmission has a high fluid tem-
perature protection mode. If the fluid tem-
perature becomes too high (for example,
climbing steep grades in high tempera-
tures with heavy loads, such as when tow-
ing a trailer), engine power and, under
some conditions, vehicle speed will be
decreased automatically to reduce the
chance of transmission damage. Vehiclespeed can be controlled with the accelera-
tor pedal, but the engine and vehicle speed
may be reduced.
WARNING
When the high fluid temperature pro-
tection mode operation occurs, vehicle
speed may be gradually reduced. The
reduced speed may be lower than
other traffic, which could increase the
chance of a collision. Be especially
careful when driving. If necessary, pull
to the side of the road at a safe place
and allow the transmission to return to
normal operation; or have it repaired if
necessary.

9-6Maintenance and schedules

• Use the Tow Mode or downshif t thetransmission to a lower gear for engine
braking when driving down steep or long
hills. This will help slow the vehicle without
applying the brakes.
• Avoid holding the brake pedal down too long or too frequently. This could cause
the brakes to overheat, resulting in re-
duced braking efficiency.
• Increase your following distance to allow for greater stopping distances while tow-
ing a trailer. Anticipate stops and brake
gradually.
• NISSAN recommends that the cruise control (if so equipped) not be used while
towing a trailer.
• While towing a trailer, do not use the fol- lowing systems (if so equipped):–– the Lane Departure Warning (LDW) sys- tem
–– the Blind Spot Warning (BSW) system
– – the Intelligent Cruise Control (ICC) sys-
tem
– – the Automatic Emergency Braking
(AEB) system
– – the Intelligent Forward Collision Warn-
ing (I-FCW) system
– – the Rear Automatic Braking (RAB) sys-
tem –
– the Moving Object Detection (MOD)
system
– – the Cross Traffic Alert system
–– the Rear Sonar system
• Some states or provinces have specific regulations and speed limits for vehicles
that are towing trailers. Obey the local
speed limits.
• Check your hitch, trailer wiring harness connections, and trailer wheel lug nuts
af ter 50 miles (80 km) of travel and at
every break.
• When launching a boat, don't allow the water level to go over the exhaust tail
pipe or rear bumper.
• Make sure you disconnect the trailer lights before backing the trailer into the
water or the trailer lights may burn out.
When towing a trailer, final drive gear oil
should be replaced and transmission oil/
fluid should be changed more fre-
quently. For additional information, see
the “Do-it-yourself ” section of this
manual.Tow mode
Using tow mode is recommended when
pulling a heavy trailer or hauling a heavy
load. Press the TOW MODE switch to acti-
vate tow mode. The indicator light on the
TOW MODE switch illuminates when tow
mode is selected. Press the TOW MODE
switch again to turn tow mode off. Tow
mode is automatically canceled when the
ignition switch is turned off.
Tow mode includes the following features:
• Grade logic — Adjusts transmission shif ts when pulling a trailer or hauling a load up
a grade.
• Downhill Speed Control (DSC) — auto- matically downshif ts when driving down
a grade with a trailer or heavy load to help
control vehicle speed.
Driving the vehicle in the tow mode with no
trailer/load or light trailer/light load will not
cause any damage. However, fuel
economy may be reduced and the
transmission/engine driving characteris-
tics may feel unusual.
