This vehicle is equipped with a speedometer
and odometer. The speedometer is located
on the right side of the meter cluster. The
odometer is located within the vehicle infor-
mation display.

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 tem-
perature. The engine coolant temperature 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 driving con-
ditions.
CAUTION
If the gauge indicates coolant temperature
near the hot (H) end of the normal range,
reduce vehicle speed to decrease tempera-
ture. If the gauge is over the normal range,
stop the vehicle as soon as safely possible. If
the engine is overheated, continued opera-
tion of the vehicle may seriously damage
the engine. For additional information, re-
fer to “If your vehicle overheats” in the “In
case of emergency” section of this manual
for immediate action required.

manual.
OPERATING TIPS
The sensors,AandBon the instrument
panel, help the system maintain a constant
temperature. Do not put anything on or
around these sensors. ∙ When the engine coolant temperature
and outside air temperature are low, the
air may flow from defroster or feet vents
to initialize automatic heating mode. This
is not a malfunction. After the coolant
temperature warms up, air will flow nor-
mally from the feet vents
∙ A visible mist may be seen coming from the ventilators in hot, humid conditions as
the air is cooled rapidly. This does not
indicate a malfunction.

PRECAUTIONS ON CRUISE

2. SET– switch
3. Cruise control
switch
4. CANCEL switch
∙ If the cruise control system malfunctions, it will cancel automatically.
The
indicator in the vehicle infor-
mation display will blink to warn the
driver. ∙ If the engine coolant temperature be-
comes excessively high, the cruise control
system will be canceled automatically.
∙ If the
indicator blinks, turn the
Cruise control
switch off and have
the system checked. It is recommended
that you visit an INFINITI retailer for this
service.
∙
Theindicator may sometimes blink
when the Cruise control
switch is
turned on while pushing the RES+, SET– or
CANCEL switch. To properly set the cruise
control system, perform the steps below.
WARNING
Do not use the cruise control when driving
under the following conditions:
∙ When it is not possible to keep the vehicle at a set speed
∙ In heavy traffic or in traffic that varies in speed
∙ On winding or hilly roads
∙ On slippery roads (rain, snow, ice, etc.)
∙ In very windy areas
Doing so could cause a loss of vehicle con-
trol and result in an accident.

DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, including
the engine block. Refill before operating the
vehicle. For additional information, refer to
“Changing engine coolant” in the “Do-it-
yourself” section of this manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed toprovide 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,
INFINITI recommends the use of MUD &
SNOW or ALL SEASON TIRES on all
four wheels. It is recommended that you
visit an INFINITI retailer for the tire type,
size, speed rating and availability infor-
mation.
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, refer to “Tire chains” in the
“Do-it-yourself” section of this manual.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items
be carried in the vehicle during winter:
∙ A scraper and stiff-bristled brush to re- move ice and snow from the windows
and wiper blades.
∙ A sturdy, flat board to be placed under the jack to give it firm support.
∙ A shovel to dig the vehicle out of snow- drifts.
∙ Extra washer fluid to refill the windshield-washer fluid reservoir.
DRIVING ON SNOW OR ICE
WARNING
∙ Wet ice (32°F, 0°C and freezing rain),very cold snow or ice can be slick and very
hard to drive on. The vehicle will have
much less traction or “grip” under these
conditions. Try to avoid driving on wet
ice until the road is salted or sanded.
∙ Whatever the condition, drive with cau- tion. Accelerate and slow down with
care. If accelerating or downshifting too
fast, the drive wheels will lose even more
traction.
∙ Allow more stopping distance under these conditions. Braking should be
started sooner than on dry pavement.
∙ Allow greater following distances on slippery roads.
∙ Watch for slippery spots (glare ice). These may appear on an otherwise clear
road in shaded areas. If a patch of ice is
seen ahead, brake before reaching it. Try
not to brake while on the ice, and avoid
any sudden steering maneuvers.
∙ Do not use the cruise control on slippery roads.
5-192Starting and driving

∙ Snow can trap dangerous exhaust gasesunder your vehicle. Keep snow clear of
the exhaust pipe and from around your
vehicle.
ENGINE BLOCK HEATER (if so
equipped)
Engine block heaters are used to assist with
cold temperature starting.
The engine block heater should be used when
the outside temperature is 20°F (-7°C) or
lower.
WARNING
∙ Do not use your engine block heater withan ungrounded electrical system or a
2-pronged adapter. You can be seriously
injured by an electrical shock if you use an
ungrounded connection.
∙ Disconnect and properly store the engine block heater cord before starting the en-
gine. Damage to the cord could result in
an electrical shock and can cause serious
injury. ∙ Use a heavy-duty 3-wire, 3-pronged ex-
tension cord rated for at least 10 A. Plug
the extension cord into a Ground Fault
Interrupt (GFI) protected, grounded
110-VAC outlet. Failure to use the
proper extension cord or a grounded out-
let can result in a fire or electrical shock
and cause serious personal injury.
To use the engine block heater: 1. Turn the engine off.
2. Open the hood and unwrap the engine block 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.

CAUTION
∙ Continuously Variable Transmission(CVT) models cannot be push-started or
tow-started. Attempting to do so may
cause transmission damage.
∙ Do not push start this vehicle. The three- way catalyst may be damaged.
WARNING
∙ Do not continue to drive if your vehicleoverheats. Doing so could cause engine
damage or a vehicle fire.
∙ To avoid the danger of being scalded, never remove the coolant reservoir cap
while the engine is still hot. When the
coolant reservoir cap is removed, pres-
surized hot water will spurt out, possibly
causing serious injury.
∙ Do not open the hood if steam is coming out.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading),
or if you feel a lack of engine power, detect
abnormal noise, etc. take the following steps. 1. Move the vehicle safely off the road, apply the parking brake and engage the
P (Park) position.
Do not stop the engine.
2. Turn off the air conditioner. Open all the windows, move the heater or air condi-
tioner temperature control to maximum
hot and fan control to high speed. 3. Get out of the vehicle. Look and listen for
steam or coolant escaping from the ra-
diator before opening the hood. (If
steam or coolant is escaping, turn off the
engine.) Do not open the hood further
until no steam or coolant can be seen.
4. Open the engine hood.
WARNING
If steam or water is coming from the engine,
stand clear to prevent getting burned.
5. Visually check drive belts for damage or looseness. Also check if the cooling fan is
running. The radiator hoses and radiator
should not leak water. If coolant is leak-
ing, the water pump belt is missing or
loose, or the cooling fan does not run,
stop the engine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or get caught in, engine belts or the
engine cooling fan. The engine cooling fan
can start at any time.
