2019 NISSAN ALTIMA air condition

∙ The ICC system does not react to sta-tionary and slow moving vehicles.
∙ Always drive carefully and attentively when using the ICC system. Read and
understand the Owner’s Manual thor-
oughly before using the ICC system.
To avoid serious injury or death, do
not rely on the system to prevent ac-
cidents or to control the vehicle’s
speed in emergency situations. Do
not use the ICC system except in ap-
propriate road and traffic conditions.
ICC system operation
The ICC system is designed to maintain a
selected distance from the vehicle in front
of you and can reduce the speed to match
a slower vehicle ahead. The system decel-
erates the vehicle as necessary and if the
vehicle ahead comes to a stop, the vehicle
decelerates to a standstill. However, the ICC
system can only apply up to 40% of the
vehicle’s total braking power. This system
should only be used when traffic condi-
tions allow vehicle speeds to remain fairly
constant or when vehicle speeds change
gradually. If a vehicle moves into the travel-
ing lane ahead or if a vehicle traveling
ahead rapidly decelerates, the distance be-
tween vehicles may become closer be- cause the ICC system cannot decelerate
the vehicle quickly enough. If this occurs,
the ICC system sounds a warning chime
and blinks the system display to notif y the
driver to take necessary action.
The ICC system cancels and a warning
chime sounds if the speed is below ap-
proximately 15 mph (24 km/h) and a vehicle
is not detected ahead.
The ICC system operates as follows:
∙ When there are no vehicles traveling ahead, the ICC system maintains the
speed set by the driver. The set speed
range is between approximately 20 and
90 mph (32 and 144 km/h).
∙ When there is a vehicle traveling ahead, the ICC system adjusts the speed to
maintain the distance, selected by the
driver, from the vehicle ahead. If the ve-
hicle ahead comes to a stop, the vehicle
decelerates to a standstill. Once your
vehicle stops, the ICC system keeps the
vehicle stopped.
∙ When your vehicle is stopped for less than 3 seconds and the vehicle ahead
begins to move, your vehicle will start
moving again automatically. ∙ When your vehicle is at a standstill for
more than 3 seconds and the vehicle
ahead begins to accelerate, push the
RES+ switch or lightly depress the accel-
erator pedal. The ICC system starts to
follow the vehicle ahead.
∙ When the vehicle traveling ahead moves to a different traveling lane, the
ICC system accelerates and maintains
vehicle speed up to the set speed.
The ICC system does not control vehicle
speed or warn you when you approach
stationary and slow moving vehicles. You
must pay attention to vehicle operation to
maintain proper distance from vehicles
ahead when approaching toll gates or traf-
fic congestion.
5-104Starting and driving

When driving on some roads, such as wind-
ing, hilly, curved, narrow roads, or roads
which are under construction, the radar
sensor may detect vehicles in a different
lane, or may temporarily not detect a ve-
hicle traveling ahead. This may cause the
radar system to decelerate or accelerate
the vehicle.
The detection of vehicles may also be af-
fected by vehicle operation (steering ma-
neuver or traveling position in the lane, etc.)
or vehicle condition.If this occurs, the ICC system may warn you
by blinking the system indicator and
sounding the chime unexpectedly. You will
have to manually control the proper dis-
tance away from the vehicle traveling
ahead.
Automatic cancellation
The following are conditions in which the
ICC system may be temporarily unavail-
able. In these instances, the ICC system
may not cancel and may not be able to
maintain the selected following distance
from the vehicle ahead.Condition A
Under the following conditions, the ICC system
is automatically canceled. A chime will sound
and the system will not be able to be set:
∙ Any door is open.
∙ The driver’s seat belt is not fastened.
∙ The vehicle ahead is not detected and
your vehicle is traveling below the
speed of 15 mph (24 km/h).
∙ Your vehicle has been stopped by the ICC system for approximately 3 minutes
or longer.
∙ The shif t lever is not in the D (Drive) po- sition or manual shif t mode.
∙ The electronic parking brake is applied.
∙ The VDC system is turned off.
∙ The AEB applies harder braking.

able: Front Radar Blocked” warning mes-
sage will appear in the vehicle information
display.
Action to take:
If the warning message appears, stop the
vehicle in a safe place, place the shif t lever
in the P (Park) position, and turn the engine
off. When the radar signal is temporarily
interrupted, clean the sensor area of the
front bumper and restart the engine. If the
“Not Available: Front Radar Blocked” warn-
ing message continues to be displayed,
have the system checked. It is recom-
mended that you visit a NISSAN dealer for
this service.
Condition C
When driving on roads with limited road
structures or buildings (for example, long
bridges, deserts, snow fields, driving next to
long walls), the system may illuminate the
system warning light and display the “Not
Available: Front Radar Blocked” message. Action to take:
When the above driving conditions no lon-
ger exist, turn the system back on.
ICC system malfunction
If the ICC system malfunctions, it will be
turned off automatically, a chime will
sound, and the speed control status warn-
ing (orange) will illuminate.
Action to take:
If the warning light comes on, stop the ve-
hicle in a safe place. Turn the engine off,
restart the engine and set the ICC system
again. If it is not possible to set the ICC
system or the indicator stays on, it may be
a malfunction. Although the normal driving
can be continued, the ICC system should
be inspected. It is recommended that you
visit a NISSAN dealer for this service.
ICC sensor maintenance
The radar sensor is located on the front of
the vehicle.

WARNING
Steering Assist is not a system for
hands-free driving. Always keep your
hands on the steering wheel and drive
your vehicle safely. Failure to do so
could cause a collision resulting in seri-
ous personal injury or death.
NOTE:
If the driver lightly touches (instead of
firmly grips) the steering wheel, the
steering torque sensor may not detect
the driver’s hand(s) on the wheel and a
sequence of warnings may occur. When
the driver holds and operates the steer-
ing wheel again, the warnings turn off.
Steering Assist limitations
WARNING
∙ In the following situations, the cam- era may not detect lane markers cor-
rectly or may detect lane markers in-
correctly 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 dis- continued lane markers
– When driving on roads with a wid- ening 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 remain-
ing af ter road repairs (the Steering
Assist could detect 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.

CAUTION
During the first 1,200 miles (2,000 km),
follow these recommendations to ob-
tain maximum engine performance
and ensure the future reliability and
economy of your new vehicle. Failure to
follow these recommendations may re-
sult in shortened engine life and re-
duced engine performance.∙ Avoid driving for long periods at con- stant speed, either fast or slow, and 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 pos- sible. 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 pos-
sible.
2. Maintain Constant Speed
∙ Look ahead to try and anticipate and minimize stops.
∙ Synchronizing your speed with traffic lights allows you to reduce your num-
ber 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
Distances
∙ Observing the speed limit and not exceeding 60 mph (97 km/h) (where
legally allowed) can improve fuel effi-
ciency due to reduced aerodynamic
drag.
∙ Maintaining a safe following distance behind other vehicles reduces un-
necessary braking.
∙ Safely monitoring traffic to anticipate changes in speed permits reduced
braking and smooth acceleration
changes.
∙ Select a gear range suitable to road conditions.
