SPEEDOMETER AND
ODOMETER
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.

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 foot out-
lets to initialize automatic heating mode.
This is not a malfunction. After the cool-
ant temperature warms up, air will flow
normally from the foot outlets.
∙ 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.

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.

5-82Starting and driving

Do not attach stickers (including transparent
material), install accessories or apply addi-
tional paint near the sonar sensors.
Do not strike or damage the area around the
sonar sensors. It is recommended that you
visit an INFINITI retailer if the area around
the sonar sensors is damaged due to a colli-
sion.FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
de-icer through the key hole. If the lock be-
comes frozen, heat the key before inserting it
into the key hole, or use the INFINITI Intelli-
gent 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 winter
protection. For additional information, refer
to “Engine cooling system” in the “Do-it-
yourself” section of this manual.
BATTERY
If the battery is not fully charged during ex-
tremely cold weather conditions, the battery
fluid may freeze and damage the battery. To
maintain maximum efficiency, the battery
should be checked regularly. For additional
information, refer to “Battery” in the “Do-it-
yourself” section of this manual.
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
anti-freeze, drain the cooling system, includ-
ing 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.
COLD WEATHER DRIVING
Starting and driving5-191

∙ 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.
ACTIVE NOISE CANCELLATION
This system uses microphones1located in-
side the vehicle to detect engine booming
noise. The system then automatically gener-
ates a noise canceling sound through the
speakers and woofer (if so equipped) to re-
duce engine booming noise.
NOTE:
To operate the active noise cancellation sys-
tem properly:
∙ Do not cover the speakers or woofer (if
so equipped).

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 radiator or coolant res-
ervoir cap while the engine is still hot.
When the radiator or coolant reservoir
cap is removed, pressurized 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.
