located on the right side of the meter clus-
ter. The odometer is located within the ve-
hicle information display.

METERS AND GAUGES
2-4Instruments and controls

TACHOMETER
The tachometer indicates engine speed in
revolutions per minute (rpm). Do not rev
the engine into the red zone
1.
CAUTION
When engine speed approaches the red
zone, reduce engine speed. Operating
the engine in the red zone may cause
serious engine damage.
ENGINE COOLANT TEMPERATURE
GAUGE
The gauge indicates the engine coolant
temperature. The engine coolant tempera-
ture is within the normal range
1when
the gauge needle points within the zone
shown in the illustration.
The engine coolant temperature varies
with the outside air temperature and driv-
ing conditions.
CAUTION
If the gauge indicates coolant tempera-
ture near the hot (H) end of the normal
range, reduce vehicle speed to decrease
temperature. If the gauge is over the
normal range, stop the vehicle as soon
as safely possible. If the engine is over-
heated, continued operation of the ve-
hicle may seriously damage the engine.
For additional information, refer to “If
your vehicle overheats” in the “In case
of emergency ” section of this manual
for immediate action required.

VARIABLE COMPRESSION TURBO
(if so equipped)
Your engine is equipped with a variable
compression ratio system called “Variable
Compression Turbo”. This system can vary
the engine compression ratio continu-
ously.
According to driving conditions, the system
applies optimum compression ratio auto-
matically to achieve both high output and
high fuel economy efficiency.This is not a physical gauge. It is a display
option in the vehicle information display
that can be selected. For additional infor-
mation, refer to “Vehicle information dis-
play” in this section.
1Compression ratio status display
Displays the status of compression ra-
tio controlled by Variable Compression
Turbo. The lowest compression ratio
(8:1) and the highest (14:1) are displayed
as “Power” and ”ECO” respectively.
2Turbo charger boost pressure gauge
Displays the turbo charger boost pres-
sure.
NOTE:
Under some conditions, the compres-
sion ratio may not change. This is not a
malfunction of the system.
CAUTION
If the Variable Compression Turbo be-
comes faulty, the Malfunction Indicator
Light (MIL) may come on. For additional
information, refer to “Malfunction Indi-
cator Light (MIL)” in this section.

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, refer to “Brake fluid” in the “Do-
it-yourself ” section of this manual.
2. If the brake fluid level is correct, have the warning system checked. It is rec-
ommended that you visit a NISSAN

WARNING
∙ Your brake system may not be work-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 repairs.
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 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. 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, or missing, or if the
light remains on, have the system checked.
