SPEEDOMETER AND ODOMETER
This vehicle is equipped with a speedom-
eter and odometer. The speedometer is
located on the right side of the meter clus-
ter. The odometer is located within the ve-
hicle information display.

METERS AND GAUGES

TACHOMETER
The tachometer indicates engine speed in
revolutions per minute (rpm).Do not rev the engine into the red zone
O1.
CAUTION
When engine speed approaches the
red zone, shif t to a higher gear or re-
duce engine speed. Operating the en-
gine in the red zone may cause serious
engine damage.
ENGINE COOLANT TEMPERATURE
GAUGE
NOTE:
The ignition switch must be placed in
the ON position for the gauge to give a
reading.
The gauge indicates the engine coolant
temperature. The engine coolant tempera-
ture is within the normal range when the
reading is within the zone
OAshown in the
illustration.

LIC3427
2-6Instruments and controls

The engine coolant temperature varies
with the outside air temperature and driv-
ing conditions.
CAUTION
If the gauge indicates a coolant tem-
perature near the hot (H) end of the
normal range, reduce vehicle speed
to decrease the 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 over-
heats” (P. 6-11).
FUEL GAUGE
NOTE:
The ignition switch must be placed in
the ON position for the gauge to give a
reading.
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 low fuel warning light comes on when
the amount of fuel in the tank is getting low.
Refill the fuel tank before the gauge reg-
isters 0 (Empty).
The arrow on the fuel pump symbol
indicates the fuel-filler location.
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
vehicle inspected. It is recommended
that you visit a NISSAN dealer for this
service.

For additional information, see “Mal-
function Indicator Light (MIL)” (P. 2-11).

• If the engine coolant temperature gaugeindicates engine coolant temperature
over the normal range, turn the air condi-
tioner off. For additional information, see
“If your vehicle overheats” (P. 6-11).
• When Remote Engine Start (if so equipped) is activated, the manual cli-
mate control system will default to the
last used heating or cooling mode.
AIR FLOW CHARTS
The following charts show the button and
dial positions for MAXIMUM AND QUICK
heating, cooling or defrosting. The
air
recirculation button should always be in
the off position for heating and
defrosting.

• When the climate system is in automaticoperation and the engine coolant tem-
perature and outside air temperature are
low, the air flow outlet may default to de-
froster mode for a maximum of 2 min-
utes 30 seconds. This is not a malfunc-
tion. Af ter the engine coolant
temperature warms up, the air flow outlet
will return to foot mode and operation will
continue normally.
• When the outside and interior cabin tem- peratures are moderate to high, the in-
take setting may default to turn off air
recirculation to allow fresh air into the
passenger compartment. You may no-
tice air flow from the foot mode, bi-level
mode, or side demist vent outlets for a
maximum of 15 seconds. This may occur
when the previous climate setting was
turned off. This is not a malfunction. Af ter
the initial warm air is expelled, the intake
will return to automatic control, the air
flow outlet will return to previous settings,
and operation will continue normally. To
exit, press any climate control button.
• Keep the moonroof (if so equipped) closed while the air conditioner is in
operation. • If you feel that the air flow mode you have
selected and the outlets the air is coming
out do not match, select the
mode.
• When you change the air flow mode, you may feel air flow from the foot outlets for
just a moment. This is not a malfunction. The air conditioner system in your NISSAN
vehicle is charged with a refrigerant de-
signed with the environment in mind.
This refrigerant does not harm the
earth's ozone layer.
Special charging equipment and lubricant
is required when servicing your NISSAN air
conditioner. Using improper refrigerants or
lubricants will cause severe damage to
your air conditioner system. For additional
information, see “Air conditioner system re-
frigerant and oil recommendations”
(P. 10-8).
It is recommended that you visit a NISSAN
dealer to service your “environmentally
friendly” air conditioning system.
WARNING
The air conditioner system contains re-
frigerant under high pressure. To avoid
personal injury, any air conditioner ser-
vice should be done only by an experi-
enced technician with proper
equipment.

Do not attach stickers (including transpar-
ent material), install accessories or apply
additional paint near the sonar sensors.
Do not strike or damage the area around
the sonar sensors. It is recommended that
you visit a NISSAN dealer if the area around
the sonar sensors is damaged due to a
collision.FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
de-icer through the key hole. If the lock
becomes frozen, heat the key before in-
serting it into the key hole, or use the re-
mote keyless entry key fob or the NISSAN
Intelligent Key®.
ANTIFREEZE
In the winter when it is anticipated that the
temperature will drop below 32°F (0°C),
check the antifreeze to assure proper win-
ter protection. For additional information,
see “Engine cooling system” (P. 8-4).
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the
battery fluid may freeze and damage the
battery. To maintain maximum efficiency,
the battery should be checked regularly.
This vehicle is equipped with a sealed
maintenance free battery. It is recom-
mended that you visit a NISSAN dealer for
service.
DRAINING OF COOLANT WATER
If the vehicle is to be lef t outside without
antifreeze, drain the cooling system, includ-
ing the engine block. Refill before operatingthe vehicle. For additional information, see
“Changing engine coolant” (P. 8-5).
TIRE EQUIPMENT
1. SUMMER tires have a tread designed to
provide superior performance on dry
pavement. However, the performance of
these tires will be substantially reduced
in snowy and icy conditions. If you oper-
ate your vehicle on snowy or icy roads,
NISSAN recommends the use of MUD &
SNOW or ALL SEASON TIRES on all four
wheels. It is recommended that you visit
a NISSAN dealer for the tire type, size,
speed rating and availability information.
2. For additional traction on icy roads, studded tires may be used. However,
some U.S. states and Canadian prov-
inces prohibit their use. Check local,
state and provincial laws before install-
ing studded tires.
Skid and traction capabilities of studded
snow tires on wet or dry surfaces may be
poorer than that of non-studded snow
tires.
3. Tire chains may be used. For additional information, see “Tire chains” (P. 8-37).
COLD WEATHER DRIVING
Starting and driving5-141

To use the engine block heater:
1. Turn the engine off.
2. Open the hood and unwrap the engineblock heater cord.
3. Plug the engine block heater cord into a grounded 3-wire, 3-pronged extension
cord.
4. Plug the extension cord into a Ground Fault Interrupt (GFI) protected, grounded
110-volt AC (VAC) outlet.
5. The engine block heater must be plugged in for at least2-4hours, de-
pending on outside temperatures, to
properly warm the engine coolant. Use
an appropriate timer to turn the engine
block heater on.
6. Before starting the engine, unplug and properly store the cord to keep it away
from moving parts.
