Steering Assist limitations
WARNING
• In the following situations, the camera
may not detect lane markers correctly or
may detect lane markers incorrectly and
the Steering Assist may not operate
properly:
– When driving on roads where there
are multiple parallel lane markers,
lane markers that are faded or not
painted clearly, nonstandard lane
markers, or lane markers covered
with water, dirt, snow, etc.
– When driving on roads with discon-
tinued lane markers
– When driving on roads with a widen-
ing or narrowing lane width –
When driving on roads where there
are multiple lanes or unclear lane
markers due to road construction
– When driving on roads where there
are sharply contrasting objects, such
as shadows, snow, water, wheel ruts,
seams, or lines remaining after road
repairs (the Steering Assist could de-
tect these items as lane markers)
– When driving on roads where the
traveling lane merges or separates
• Do not use the Steering Assist under the
following conditions because the system
may not properly detect lane markers.
Doing so could cause a loss of vehicle
control and result in an accident.
– During bad weather (rain, fog, snow,
dust, etc.)

up by the wheels of other vehicles
– When dirt, oil, ice, snow, water, or an-
other object adheres to the camera
unit
– When the lens of the camera unit is
foggy
– When strong light (for example, sun-
light or high beams from oncoming
vehicles) shines on the camera –
When the headlights are not bright
due to dirt on the lens or the head-
lights are off in tunnels or darkness
– When a sudden change in brightness
occurs (for example, when the vehicle
enters or exits a tunnel or is under a
bridge)
– When driving on roads where the
traveling lane merges or separates or
where there are temporary lane
markers because of road
construction

Starting and driving5-97

The AWD high temperature message may be
displayed while trying to free a stuck vehicle
due to increased oil temperature. The driving
mode may change to 2-Wheel Drive (2WD).
If this message is displayed, stop the vehicle
with the engine idling, as soon as it is safe to
do so. Then if the message turns off, you can
continue driving.The tire size message may be displayed if
there is a large difference between the diam-
eters of front and rear wheels. Pull off the
road in a safe area, with the engine idling.
Check that all tire sizes are the same, that the
tire pressure is correct and that the tires are
not excessively worn.
If any warning messages continue to be dis-
played, have your vehicle checked as soon as
possible. It is recommended that you visit an
INFINITI retailer for this service.
WARNING
• Do not drive beyond the performance ca-
pability of the tires. Accelerating quickly,
sharp steering maneuvers or sudden
braking may cause loss of control, even
with Intelligent AWD engaged.
• For AWD equipped vehicles, do not at-
tempt to raise two wheels off the ground
and shift the transmission to any drive or
reverse position with the engine running.
Doing so may result in drivetrain damage
or unexpected vehicle movement which
could result in serious personal injury or
vehicle damage.
• Do not attempt to test an AWD
equipped vehicle on a 2-wheel dyna-
mometer (such as the dynamometers
used by some states for emissions test-
ing) or similar equipment even if the
other two wheels are raised off the
ground. Make sure that you inform the
test facility personnel that your vehicle is
equipped with AWD before it is placed
on a dynamometer. Using the wrong test
equipment may result in drivetrain dam-
age or unexpected vehicle movement
which could result in serious personal in-
jury or vehicle damage.

CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface andapply the parking brake.
2. Start the engine and let it idle until it reaches operating temperature.
3. Turn off the engine. Wait more than 10
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 between the H (High)
and L (Low) marksOB. This is the normal
operating oil level range. If the oil level is
below the L (Low) mark
OA, remove the oil
filler cap and pour recommended oil
through the opening. Do not fill oil level
above H (High) mark
OC.
6. Recheck the oil level with the dipstick.
It is normal to add some oil between oil main-
tenance intervals or during the break-in pe-
riod, depending on the severity of operating
conditions.
CAUTION
Oil level should be checked regularly. Oper-
ating the engine with an insufficient
amount of oil can damage the engine, and
such damage is not covered by warranty.

9-4Maintenance and schedules

To help ensure smooth, safe and economical
driving, INFINITI provides two maintenance
schedules that may be used, depending upon
the conditions in which you usually drive.
These schedules contain both distance and
time intervals, up to 90,000 miles (144,000
km)/144 months. For most people, the
odometer reading will indicate when service
is needed. However, if you drive very little,
your vehicle should be serviced at the regular
time intervals shown in the schedule.
After 90,000 miles (144,000 km)/144
months, continue maintenance at the same
mileage/time intervals.
