4. Distance to empty (dte — MILES or
km)
The distance to empty (dte) mode provides you
with an estimation of the distance that can be
driven before refueling. The dte is constantly
being calculated, based on the amount of fuel
in the fuel tank and the actual fuel consump-
tion.
The display is updated every 30 seconds.
The dte mode includes a low range warning
feature. If the fuel level is low, the warning is
displayed on the screen.
When the fuel level drops even lower, the dte
display will change to “——”.
●If the amount of fuel added is small, the
display just before the ignition switch is
pushed to the OFF position may continue to
be displayed.
● When driving uphill or rounding curves, the
fuel in the tank shifts, which may momen-
tarily change the display.
5. Outside air temperature (ICY — °F
or °C)
The outside air temperature is displayed in °F or
°C in the range of 22 to 131°F (30 to 55°C). The outside air temperature mode includes a
low temperature warning feature. If the outside
air temperature is below 37°F (3°C), the warning
is displayed on the screen.
The outside temperature sensor is located in
front of the radiator. The sensor may be affected
by road or engine heat, wind directions and
other driving conditions. The display may differ
from the actual outside temperature or the
temperature displayed on various signs or bill-
boards.

When performing any inspection or mainte-
nance work on your vehicle, always take care to
prevent serious accidental injury to yourself or
damage to the vehicle. The following are gen-
eral precautions which should be closely ob-
served.
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 selector lever to P (Park).
● Be sure the ignition switch is in the OFF or
LOCK position when performing any parts
replacement or repairs.
● Never connect or disconnect the battery or
any transistorized component while the ig-
nition switch is in the ON position.
● Never leave the engine or automatic trans-
mission related component harnesses dis-
connected while the ignition 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
moving parts. ●
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 whenever 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 sup-
ported 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 warning, even if the ignition
key is in the OFF position and the engine is
not running. To avoid injury, always discon-
nect the negative battery cable before work-
ing near the fan.
● On gasoline engine models, the fuel filter or
fuel lines should be serviced by an INFINITI
retailer because the fuel lines are under high
pressure even when the engine is off.
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 engine oil and
coolant. Improperly disposed engine oil,
coolant, and/or other vehicle fluids can dam-
age the environment. Always conform to lo-
cal regulations for disposal of vehicle fluid.
This “8. Maintenance and do-it-yourself” sec-
tion gives instructions regarding only those
items which are relatively easy for an owner to
perform.
A genuine INFINITI Service Manual is also avail-
able. (See “OWNER’S MANUAL/SERVICE
MANUAL ORDER INFORMATION” in the “9. Tech-
nical and consumer information” section.)
You should be aware that incomplete or im-
proper servicing may result in operating diffi-
culties or excessive emissions, and could affect
your warranty coverage. If in doubt about any
servicing, we recommend that it be done by an
INFINITI retailer.
MAINTENANCE PRECAUTIONS
Maintenance and do-it-yourself8-5

CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface andapply the parking brake.
2. Run the engine until it reaches operating temperature.
3. Turn off the engine. Wait more than 15
minutes for the oil to drain back into the oil
pan.
4. Remove the dipstick and wipe it clean. Reinsert it all the way.
5. Remove the dipstick again and check the oil level. It should be within the range
1.
If the oil level is below
2, remove the oil
filler cap and pour recommended oil
through the opening. Do not overfill
3.6. Recheck oil level with the dipstick.
It is normal to add some oil between oil mainte-
nance intervals or during the break-in period,
depending on the severity of operating condi-
tions.
CAUTION
Oil level should be checked regularly. Operat-
ing the engine with an insufficient amount of oil
can damage the engine, and such damage is
not covered by warranty.
CHANGING ENGINE OIL AND FILTER
Vehicle set-up
1. Park the vehicle on a level surface and
apply the parking brake.
2. Run the engine until it reaches operating temperature.
3. Turn the engine off and wait more than 15 minutes.
4. Raise and support the vehicle using a suitable floor jack and safety jack stands.
●Place the safety jack stands under the
vehicle jack-up points.
● A suitable adapter should be attached to
the jack stand saddle.
5. Remove the engine undercover.
● Remove the bolts that hold the under-
cover in place.
CAUTION
Make sure the correct lifting and support
points are used to avoid vehicle damage.

● Check your local regulations.
4. (Perform steps 4 to 7 only when the
engine oil filter change is needed.)
Loosen the oil filter2with an oil filter
wrench. Remove the oil filter by turning it by
hand.
5. Wipe the engine oil filter mounting sur- face with a clean rag.
CAUTION
Be sure to remove any old rubber gasket re-
maining on the mounting surface of the engine.
Failure to do so could lead to engine damage.
6. Coat the gasket on the new filter with clean engine oil.
7. Screw in the oil filter clockwise until a slight resistance is felt, then tighten ad-
ditionally more than 2/3 turn.
Oil filter tightening torque:11 to 15 ft-lb
(15 to 21 N·m)
8. Clean and re-install the drain plug with a
new washer. Securely tighten the drain
plug with a wrench.
Drain plug tightening torque:22 to 29 ft-lb
(29 to 39 N·m)
Do not use excessive force.
9. Refill engine with recommended oil and install the oil filler cap securely.
CAUTION
The dipstick must be inserted in place to pre-
vent oil spillage from the dipstick hole while
filling the engine with oil.
See “CAPACITIES AND RECOMMENDED FUEL/ LU-
BRICANTS” in the “9. Technical and consumer
information” section for drain and refill capacity.
The drain and refill capacity depends on the oil
temperature and drain time. Use these specifica-
tions for reference only. Always use the dipstick
to determine the proper amount of oil in the
