(1) If towing a trailer, using a camper or a
car-top carrier, or driving on rough or muddy
roads, change (not just inspect) oil every
20,000 miles (32,000 km) or 24 months.(2) If the oil replacement indicator is dis-
played, change the engine oil and filter within
two weeks or less than 500 miles (800 km).
(3) If operating mainly in dusty conditions,
more frequent maintenance may be required.
* Maintenance items and intervals with“*”
are recommended by NISSAN for reliable ve-
hicle operation. The owner need not perform
such maintenance in order to maintain the
emission warranty or manufacturer recall li-

LOG-IN FUNCTION
After setting up the user information, the
system will automatically recognize the user
upon turning on the vehicle.
There will be a personalized welcome greet-
ing and screen prompt to log in.
This feature allows four drivers to use their
own registration, drive mode, driving posi-
tion, air conditioner, and auto settings and
memorizes these custom settings.
The log-in user can be changed on the wel-
come greeting screen or the User List screen.
For additional information, refer to the sepa-
rate INFINITI InTouch™ Owner’s Manual.
The log-in function is linked to the following
features:
• Meter
• Audio
• Navigation system display
• Navigation settings
• Air conditioner
• Memory seat (if so equipped)
• Engine/transmission
• Steering
• Suspension (if so equipped)
• Active trace control system• Driver assistance except for the Forward
Emergency Braking (FEB) with Pedestrian
Detection system (if so equipped)
• Body Control Module (BCM)
The
button will be on the INFINITI
Intelligent Key if the vehicle has Remote En-
gine Start. This feature allows the engine to
start from outside the vehicle.
Vehicles with an automatic climate control
system will default to either a heating or
cooling mode depending on outside and
cabin temperatures. For additional informa-
tion, see. “Remote Engine Start with Intelli-
gent Climate Control” (P. 4-35).
Laws in some local communities may restrict
the use of remote starters. For example,
some laws require a person using Remote
Engine Start to have the vehicle in view.
Check local regulations for any requirements.

3-18Pre-driving checks and adjustments

–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
– When there is a lane closure due to
road repairs
– When driving on a bumpy road sur-
face, such as an uneven dirt road
– When driving on sharp curves or
winding roads
– When driving on repeated uphill and
downhill roads
• Do not use the Steering Assist under the
following conditions because the system
will not operate properly:
– When driving with a tire that is not
within normal tire conditions (for ex-
ample, tire wear, abnormal tire pres-
sure, installation of a spare tire, tire
chains, nonstandard wheels) –
When the vehicle is equipped with
non-original brake or suspension
parts
– When an object that obstructs the
camera unit detection range is
attached
– When excessively heavy baggage is
loaded in the rear seat or luggage
area of your vehicle
– When the vehicle load capacity is
exceeded
– When towing a trailer or other vehicle
• Excessive noise will interfere with the
warning chime sound, and the beep may
not be heard.
• For the ProPILOT Assist system to oper-
ate properly, the windshield in front of
the camera must be clean. Replace worn
wiper blades. The correct size wiper
blades must be used to help make sure
the windshield is kept clean. Only use
Genuine INFINITI wiper blades, or
equivalent wiper blades, that are specifi-
cally designed for use on your vehicle
model and model year. It is recommended
that you visit your INFINITI retailer for
the correct parts for your vehicle.Steering Assist temporary standby
Automatic standby due to driving operation:
When the driver activates the turn signal, the
Steering Assist is temporarily placed in a
standby mode. (The Steering Assist restarts
automatically when the operating conditions
are met again.)
Automatic standby:
In the following cases, a warning message is
displayed along with the chime, and the
Steering Assist is placed in a temporary
standby mode. (The Steering Assist restarts
automatically when the operating conditions
are met again.)
• When lane markers on both sides are no longer detected
• When a vehicle ahead is no longer detected under approximately 37 mph (60 km/h)
Steering Assist cancel
Under the following conditions, the Steering
Assist cancels, and the Steering Assist status
indicator and the Steering Assist indicator
turn off:
