ENGINE COMPARTMENT

Follow these easy-to-use Fuel Efficient
Driving Tips to help you achieve the most
fuel economy from your vehicle.
1. Use smooth accelerator and brake pedal
application.
.Avoid rapid starts and stops..Use smooth, gentle accelerator and
brake application whenever possible.
.Maintain constant speed while com-
muting and coast whenever possible.
2. Maintain constant speed.
.Look ahead to try and anticipate and
minimize stops.
.Synchronizing your speed with traffic
lights allows you to reduce your
number of stops.
.Maintaining a steady speed can mini-
mize red light stops and improve fuel
efficiency.
3. Use air conditioning (A/C) at higher
vehicle speeds.
.Below 40 MPH (64 km/h), it is more
efficient to open windows to cool the
vehicle due to reduced engine load.
.Above 40 MPH (64 km/h), it is more
efficient to use A/C to cool the
vehicle due to increased aerodynamic
drag.
.Recirculating the cool air in the cabin
when the A/C is on reduces cooling
load.4. Drive at economical speeds and dis-
tances.
.Observing the speed limit and not
exceeding 60 MPH (97 km/h) (where
legally allowed) can improve fuel
efficiency due to reduced aerody-
namic drag.
.Maintaining a safe following distance
behind other vehicles reduces unne-
cessary braking.
.Safely monitoring traffic to anticipate
changes in speed permits reduced
braking and smooth acceleration
changes.
.Select a gear range suitable to road
conditions.
5. Use cruise control.
.Using cruise control during highway
driving helps maintain a steady speed.
.Cruise control is particularly effective
in providing fuel savings when driving
on flat terrains.
6. Plan for the shortest route.
.Utilize a map or navigation system to
determine the best route to save time.
7. Avoid idling.
.Shutting off your engine when safe
for stops exceeding 30-60 seconds
saves fuel and reduces emissions.8. Buy an automated pass for toll roads.
.Automated passes permit drivers to
use special lanes to maintain cruising
speed through the toll and avoid
stopping and starting.
9. Winter warm up.
.Limit idling time to minimize impact to
fuel economy.
.Vehicles typically need no more than
30 seconds of idling at start-up to
effectively circulate the engine oil
before driving.
.Your vehicle will reach its ideal oper-
ating temperature more quickly while
driving versus idling.
10. Keeping your vehicle cool.
.Park your vehicle in a covered parking
area or in the shade whenever possi-
ble.
.When entering a hot vehicle, opening
the windows will help to reduce the
inside temperature faster, resulting in
reduced demand on your A/C system.

FUEL EFFICIENT DRIVING TIPS

5-140Starting and driving
NOTE:
It may take some time until the Idling Stop
System activates under the following con-
ditions:
.when the battery is discharged.
.when the outside temperature is low or
high.
.when the battery is replaced or the
battery terminal is disconnected for
extended periods and then reconnected.
NOTE:
When the Idling Stop System indicator light
illuminates, the engine starts running auto-
matically under at least one of the following
conditions:
.The brake pedal is released with the shift
lever in the D (Drive) or N (Neutral)
position.
.The shift lever is placed in the D (Drive)
or R (Reverse) position from the N
(Neutral) or P (Park) position.
.The driver’s seat belt is unfastened, or
the driver’s door is open.
.The battery voltage becomes low (due to
electrical load from other vehicle sys-
tems like headlights, heaters, etc., or
auxiliary devices connected to the 12
volt socket inside the vehicle).
.The vehicle speed is above about 1 MPH
(2 km/h)..The front defroster is operated.
.The rear window defroster is operated.
.When the temperature inside the vehicle
is lower than approximately 68°F
(20°C).
.When the temperature inside the vehicle
is higher than approximately 86°F
(30°C). (When the air conditioner is
off, the Idling Stop System will operate.)
.When the front defroster is turned on.
(The engine may not starts depending
on the outside temperature.)
.When more than 3 minutes have elapsed
since the Idling Stop System was active.
.When the accelerator pedal is depressed.
.When the steering wheel is operated.
(The steering wheel operation may be-
come heavy, but this is not a malfunc-
tion.)
.When the battery capacity is low.
.When the power consumption is high.
.When the shift lever is placed in the R
(Reverse) position.
NOTE:
The following condition will prevent the
Idling Stop System from automatically re-
starting the engine. Starting the engine
with the ignition switch operation is then
necessary:.The hood is open.
Use this system while waiting at stoplight,
etc. When the vehicle is stopped for long
periods of time, turn off the engine.
When the engine is stopped by the Idling
Stop System, heating, cooling and dehumi-
difying functions will be deactivated. To
avoid the air conditioning functions from
being deactivated, turn off the Idling Stop
mode by pushing the Idling Stop OFF switch.
RETROGRADE MOVEMENT
CONTROL FUNCTION
This system is designed to reduce the retro-
grade movement that occurs while the
driver’s foot changes from depressing the
brake pedal to the accelerator pedal when
moving the vehicle while the Idling Stop
System is active on a hilly road.
IDLING STOP SYSTEM DISPLAY
The status of the Idling Stop System can be
checked in the vehicle information display.

automatically stopping during the same
journey.
.Whenever the Idling Stop System is
deactivated the indicator light
on the
Idling Stop OFF switch illuminates. In
this condition the Idling Stop System
cannot prevent unnecessary fuel con-
sumption, exhaust emissions, or noise
during your journey.
.If the Idling Stop System is malfunction-
ing, the indicator light
on the Idling
Stop OFF switch illuminates.
NOTE:
The Idling Stop System ON or OFF message
is displayed for a few seconds in the vehicle
information display when the Idling Stop
OFF switch is pushed. See “Idling Stop
System ON or OFF” (P.5-141).
FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
deicer through the key hole. If the lock
becomes frozen, heat the key before insert-
ing it into the key hole or use the Intelligent
Key system.
ANTIFREEZE
In the winter when it is anticipated that the
outside temperature will drop below 32°F
(0°C), check antifreeze to assure proper
winter protection. For additional informa-
tion, see “Engine cooling system (for
VR30DDTT engine models)” (P.8-6), “En-
gine cooling system (for 2.0L turbo gasoline
engine models)” (P.8-8) or “Intercooler cool-
ing system (for VR30DDTT engine models)”
(P.8-9).
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the bat-
tery fluid may freeze and damage the
battery. To maintain maximum efficiency,
the battery should be checked regularly. For
additional information, see “Battery” (P.8-
16).
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, includ-
ing the engine block. Refill before operating
the vehicle. For details, see “Engine cooling
system (for VR30DDTT engine models)”
(P.8-6) or “Engine cooling system (for 2.0L
turbo gasoline engine models)” (P.8-8).
TIRE EQUIPMENT
SUMMER tires have a tread designed to
provide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate 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 you consult an INFINITI re-
tailer for the tire type, size, speed rating and
availability information.
For additional traction on icy roads, studded
tires may be used. However, some U.S.
states and Canadian provinces prohibit their
use. Check local, state and provincial laws
before installing 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.
Tire chains may be used. For details, see
“Tire chains” (P.8-40) of this manual.

COLD WEATHER DRIVING

To start your engine with a booster battery,
the instructions and precautions below must
be followed.
WARNING
.If done incorrectly, jump starting can
lead to a battery explosion, resulting
in severe injury or death. It could also
damage your vehicle.
.Explosive hydrogen gas is always
present in the vicinity of the battery.
Keep all sparks and flames away from
the battery.
.Do not allow battery fluid to come
into contact with eyes, skin, clothing
or painted surfaces. Battery fluid is a
corrosive sulphuric acid solution
which can cause severe burns. If the
fluid should come into contact with
anything, immediately flush the con-
tacted area with water.
.Keep the battery out of the reach of
children.
.The booster battery must be rated at
12 volts. Use of an improperly rated
battery can damage your vehicle.
.Whenever working on or near a
battery, always wear suitable eye
protectors (for example, goggles orindustrial safety spectacles) and re-
move rings, metal bands, or any other
jewelry. Do not lean over the battery
when jump starting.
.Do not attempt to jump start a
frozen battery. It could explode and
cause serious injury.
.Your vehicle has an automatic engine
cooling fan. It could come on at any
time. Keep hands and other objects
away from it.
For 2.0L turbo gasoline engine models:
The vehicle has 2 batteries, a main
battery and an auxiliary battery. The
engine cannot be started if either bat-
tery is discharged. First, apply the
following procedure to the main battery
to jump-start the engine.
If the engine does not start, apply the
procedure to the auxiliary battery. For
the position of the batteries, see “Engine
compartment check locations” (P.8-4)
or “Battery” (P.8-16).
.Use the special battery that is dedi-
cated for the Idling Stop System,
with enhanced charge-discharge ca-
pacity and life performance. Using
the non-special battery could cause
early deterioration of the battery
and/or malfunction of the Idling StopSystem. For the special battery, it is
recommended to use Genuine
NISSAN parts. For more information,
contact an INFINITI retailer.
.It may take some time until the Idling
Stop System activates when the
battery is replaced or the battery
terminal is disconnected for extended
periods and then reconnected.

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 coolingfan can start at any time.
7. After the engine cools down, check the
coolant level in the reservoir tank with
the engine running. Add coolant to the
reservoir tank if necessary. Have your
vehicle repaired. It is recommended you
visit an INFINITI retailer for this service.When towing your vehicle, all State (Pro-
vincial in Canada) and local regulations for
towing must be followed. Incorrect towing
equipment could damage your vehicle. Tow-
ing instructions are available from an
INFINITI retailer. Local service operators
are familiar with the applicable laws and
procedures for towing. To assure proper
towing and to prevent accidental damage to
your vehicle, INFINITI recommends that you
have a service operator tow your vehicle. It is
advisable to have the service operator care-
fully read the following precautions.
WARNING
.Never ride in a vehicle that is being
towed.
.Never get under your vehicle after it
has been lifted by a tow truck.

When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The
following are general precautions which
should be closely observed.
WARNING
.Park the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the
vehicle from moving. Move the shift
lever to P (Park).
.Be sure the ignition switch is in the
OFF or LOCK position when per-
forming any parts replacement or
repairs.
.Never connect or disconnect the
battery or any transistorized compo-
nent while the ignition switch is in the
ON position.
.Never leave the engine or automatic
transmission related component har-
nesses disconnected while the igni-
tion switch is in the ON position.
.If you must work with the engine
running, keep your hands, clothing,
hair and tools away from moving
fans, belts and any other movingparts.
.It is advisable to secure or remove
any loose clothing and remove any
jewelry, such as rings, watches, etc.
before working on your vehicle.
.Always wear eye protection when-
ever you work on your vehicle.
.If you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.
.Never get under the vehicle while it is
supported only by a jack. If it is
necessary to work under the vehicle,
support it with safety stands.
.Keep smoking materials, flame and
sparks away from fuel tank and the
battery.
.Your vehicle is equipped with an
automatic engine cooling fan. It may
come on at any time without warn-
ing, even if the ignition key is in the
OFF position and the engine is not
running. To avoid injury, always dis-
connect the negative battery cable
before working near the fan.
.Because the fuel lines are under high
pressure even when the engine is off,
it is recommended you visit an
INFINITI retailer for service of thefuel filter or fuel lines.
CAUTION
.Do not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down.
.Avoid direct contact with used en-
gine oil and coolant. Improperly dis-
posed engine oil, coolant, and/or
other vehicle fluids can damage the
environment. Always conform to lo-
cal regulations for disposal of vehicle
fluid.
This “8. Do-it-yourself” section gives in-
structions regarding only those items which
are relatively easy for an owner to perform.
A genuine INFINITI Service Manual is also
available. (See “Owner’s Manual/Service
Manual order information” (P.10-25).)
You should be aware that incomplete or
improper servicing may result in operating
