The supplemental air bag warning lightis used to indicate malfunctions in the
pretensioner system. For additional infor-
mation, see "Supplemental air bag warning
light" (P. 1-67). If the operation of the supple-
mental air bag warning light indicates
there is a malfunction, have the system
checked. It is recommended that you visit a
NISSAN dealer for this service.
When selling your vehicle, we request that
you inform the buyer about the preten-
sioner system and guide the buyer to the
appropriate sections in this Owner's

If any of the following conditions occur, the
front air bag, side air bag, curtain air bag,
knee air bag and pretensioner systems
need servicing:
• The supplemental air bag warning lightremains on af ter approximately 7
seconds.
• The supplemental air bag warning light flashes intermittently.
• The supplemental air bag warning light does not come on at all.
Under these conditions, the front air bag,
side air bag, curtain air bag, knee air bag or
pretensioner systems may not operate
properly. They must be checked and re-
paired. It is recommended that you visit a
NISSAN dealer for this service.
WARNING
If the supplemental air bag warning
light is on, it could mean that the front
air bag, side air bag, curtain air bag,
knee air bag and/or pretensioner sys-
tems will not operate in an accident. To
help avoid injury to yourself or others,
have your vehicle checked as soon as
possible. It is recommended that you
visit a NISSAN dealer for this service.
Repair and replacement
procedure
The front air bags, side air bags, curtain air
bags, knee air bags and pretensioner(s) are
designed to inflate on a one-time-only ba-
sis. As a reminder, unless it is damaged, the
supplemental air bag warning light re-
mains illuminated af ter inflation has oc-
curred. These systems should be repaired
and/or replaced as soon as possible. It is
recommended that you visit a NISSAN
dealer for this service.
When maintenance work is required on the
vehicle, the front air bags, side air bags,
curtain air bags, knee air bags, pretension-
er(s) and related parts should be pointed
out to the person performing the mainte-
nance. The ignition switch should always
be placed in the LOCK position when work-
ing under the hood or inside the vehicle.
WARNING
• Once a front air bag, side air bag, cur-
tain air bag or knee air bag has in-
flated, the air bag module will not
function again and must be replaced.
Additionally, the activated preten-
sioner(s) must also be replaced. The
air bag module and pretensioner(s)
should be replaced. It is recom-
mended that you visit a NISSAN
dealer for this service. However, the
air bag module and pretensioner(s)
cannot be repaired.
• The front air bag, side air bag, curtain
air bag, knee air bag systems and the
pretensioner system should be in-
spected if there is any damage to the
front end or side portion of the ve-
hicle. It is recommended that you
visit a NISSAN dealer for this service.
• If you need to dispose of the supple-
mental air bag or pretensioner sys-
tems or scrap the vehicle, it is recom-
mended that you contact a NISSAN
dealer for this service. Incorrect dis-
posal procedures could cause per-
sonal injury.

CAUTION
If the gauge indicates coolant tem-
perature 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 overheated, continued operation of
the vehicle may seriously damage the
engine. For additional information, see
“If your vehicle overheats” (P. 6-19) for
immediate action required.
FUEL GAUGE
The gauge indicates the approximatefuel
level in the tank.
The gauge may move slightly during brak-
ing, turning, acceleration, or going up or
down hills.
The gauge needle returns to 0 (Empty) af-
ter the ignition switch is placed in the OFF
position.
The low fuel warning message shows in
the vehicle information display when the
amount of fuel in the tank is getting low. Refill the fuel tank before the gauge reg-
isters 0 (Empty).
The
indicates that the fuel-filler door
is located on the driver's side of the vehicle.
CAUTION
• If the vehicle runs out of fuel, the
Malfunction Indicator Light (MIL) may
come on. Refuel as soon as possible.
Af ter a few driving trips, the
light
should turn off. If the light remains on
af ter a few driving trips, have the ve-
hicle inspected. It is recommended
that you visit a NISSAN dealer for this
service.

DISTANCE TO EMPTY (DTE)
Displays the estimated distance the ve-
hicle can be driven before refueling. The
value is calculated based on recent fuel
economy, the amount of fuel remaining in
the fuel tank, and the actual fuel
consumption.
Changes in driving patterns or conditions
can cause the DTE value to vary. As a result,
the value displayed may differ from the ac-
tual distance that can be driven.
DTE display will change to “---” when the
fuel level in the tank is getting low, prior to
the fuel gauge reaching 0 (Empty).
NOTE:
• The DTE value af ter refill is estimatedbased on recent fuel economy and
amount of fuel added.
• If a small amount of fuel is added, or the ignition is on during refueling, the
display may not be updated.
• Conditions that affect the fuel economy will also affect the estimated
DTE value (city/highway driving, idle
time, remote start time, terrain, sea-
sonal weather, added vehicle weight,
added deflectors, roof racks, etc.).
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
continuously.
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, see “Vehicle information display”
(P. 2-34).
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
pressure.
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, see “Malfunction Indicator
Light (MIL)” (P. 2-15).

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 as well as
pedal travel.
