CAUTION
During the first 1,200 miles (2,000 km),
follow these recommendations to obtain
maximum engine performance and en-
sure the future reliability and economy
of your new vehicle.
Failure to follow these recommendations
may result in shortened engine life and
reduced engine performance.
.Avoid driving for long periods at constant
speed, either fast or slow. Do not run the
engine over 4,000 rpm.
.Do not accelerate at full throttle in any
gear.
.Avoid quick starts.
.Avoid hard braking as much as possible.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.

SONAR INDICATOR
When the corner of the vehicle moves closer
to an object, the corner sensor indicator
appears on the upper display.
When the center of the vehicle moves close
to an object, the center sensor indicator
appears on the upper display.
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” (P.8-3) or
“Intercooler cooling system” (P.8-5).
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-
11).
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” (P.8-3).
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.8-34) of this manual.
Intelligent All-Wheel Drive (AWD)
models
If you install snow tires, they must also be
the same size, brand, construction and tread
pattern on all four wheels.

In case of emergency6-11

CAUTION
.Do not continue to drive if your
vehicle overheats. Doing so could
cause engine damage or a vehicle fire.
.To avoid the danger of being scalded,
never remove the radiator cap while
the engine is still hot. When the
radiator 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 move the
shift lever to the P (Park) position.
Do not stop the engine.
2. Turn off the climate control. Open all the
windows, move the heater or air condi-
tioner temperature control to maximum
hot and fan control to high speed.
3. If engine overheating is caused by climb-
ing a long hill on a hot day, run the engineat a fast idle (approximately 1,500 rpm)
until the temperature gauge indication
returns to normal.
4. Get out of the vehicle. Look and listen for
steam or coolant escaping from the
radiator 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.
5. Open the engine hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
6. 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
leaking 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 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.

8-2Do-it-yourself
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.10-24).)
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and could
affect your warranty coverage.If in doubt
about any servicing, it is recommended you
have it done by an INFINITI retailer.

factory with a pre-diluted mixture of 50%
Genuine NISSAN Long Life Antifreeze/
Coolant (blue) and 50% water to provide
year-round anti-freeze and coolant protec-
tion. The anti-freeze solution contains rust
and corrosion inhibitors. Additional engine
cooling system additives are not necessary.
WARNING
.Never remove the radiator cap when
the engine is hot. Wait until the
engine and radiator cool down. Ser-
ious burns could be caused by high
pressure fluid escaping from the
radiator. See precautions in “If your
vehicle overheats” (P.6-13) of this
manual.
.The radiator is equipped with a
pressure type radiator cap. To pre-
vent engine damage, use only a

mission and/or cooling system.
.When adding or replacing coolant, be
sure to use only Genuine NISSAN
Long Life Antifreeze/Coolant (blue)
or equivalent. Genuine NISSAN Long
Life Antifreeze/Coolant (blue) is pre-
diluted to provide antifreeze protec-
tion to −34°F (−37°C). If additional
freeze protection is needed due to
weather where you operate your
vehicle, add Genuine NISSAN Long
Life Antifreeze/Coolant (blue) con-
centrate following the directions on
the container. If an equivalent cool-
ant other than Genuine NISSAN Long
Life Antifreeze/Coolant (blue) is
used, follow the coolant manufac-
ture’s instructions to maintain mini-
mum antifreeze protection to −34°F
(−37°C). The use of other types of
coolant solutions other than Genuine
NISSAN Long Life Antifreeze/Cool-
ant (blue) or equivalent may damage
the engine cooling system.
.The life expectancy of the factory-fill
coolant is 105,000 miles (168,000
km) or 7 years. Mixing any other type
of coolant other than Genuine
NISSAN Long Life Antifreeze/Cool-
ant (blue) (or equivalent coolant),
including Genuine NISSAN Long Life
Antifreeze/ Coolant (green), or theuse of non-distilled water will reduce
the life expectancy of the factory-fill
coolant. Refer to the “9. Mainte-
nance and schedules” section of this
manual for more details.

CHECKING ENGINE COOLANT
LEVEL
Check the coolant level in the reservoir tank
when the engine is running and after it
reaches normal operating temperature. If
the coolant level is below MIN level
, add
coolant up to the MAX level. If the
reservoir tank is empty, check the coolant
level in the radiatorwhen the engine is cold.
If there is insufficient coolant in the radiator,
fill the radiator with coolant up to the filler
cap above the radiator upper hose opening
and also add it to the reservoir tank up to the
MAX level
. Put on the filler cap above the
radiator upper hose and with the reservoir
cap open, start the engine. Run the engine
