2021 NISSAN ALTIMA Owners Manual

∙ The Steering Assist only steers the ve-hicle to maintain its position in the
center of a lane. The vehicle will not
steer to avoid objects in the road in
front of the vehicle or to avoid a ve-
hicle moving into your lane.
∙ It is the driver’s responsibility to stay alert, drive safely, keep the vehicle in
the traveling lane, and be in control of
the vehicle at all times. Never take
your hands off the steering wheel
when driving. Always keep your hands
on the steering wheel and drive your
vehicle safely.
∙ Always drive carefully and attentively when using the Steering Assist. Read
and understand the Owner’s Manual
thoroughly before using the Steering
Assist. To avoid serious injury or
death, do not rely on the system to
prevent accidents or to control the ve-
hicle’s speed in emergency situations.
Do not use the Steering Assist except
in appropriate road and traffic
conditions.Steering Assist operation
The Steering Assist controls the steering
system to help keep your vehicle near the
center of the lane when driving. The Steer-
ing Assist is combined with the Intelligent
Cruise Control (ICC) system. For additional
information, refer to “Intelligent Cruise Con-
trol (ICC) (for vehicles with ProPILOT Assist)”
in this section.
The Steering Assist can be activated when
the following conditions are met:
∙ The ICC system is activated.
∙ Lane markers on both sides are clearly detected.
∙ A vehicle ahead is detected (when the vehicle is driven at speeds under
37 mph [60 km/h]).
∙ The driver grips the steering wheel.
∙ The vehicle is driven at the center of the lane.
∙ The turn signals are not operated.
∙ The windshield wiper is not operated in the high (HI) speed operation (the Steer-
ing Assist function is disabled af ter the
wiper operates for approximately
10 seconds).

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

– When driving on roads where thetraveling 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
example, tire wear, abnormal tire
pressure, installation of a spare
tire, tire chains, nonstandard
wheels)
– When the vehicle is equipped with non-original brake or suspension
parts – When an object such as a sticker or
cargo obstructs the camera
– When excessively heavy baggage is loaded in the rear seat or lug-
gage 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 op- erate 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 NISSAN wiper
blades, or equivalent wiper blades,
that are specifically designed for use
on your vehicle model and model
year. It is recommended that you visit
a NISSAN dealer for the correct parts
for your vehicle.Steering Assist temporary
standby
Automatic standby due to driving opera-
tion:
When the driver activates the turn signal,
the Steering Assist is temporarily placed in

starts 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 re-
starts automatically when the operating
conditions are met again.)

CRUISE CONTROL MODE
NOTE:
ProPILOT Assist provides no approach
warnings, automatic braking, or steering
assist in the conventional (fixed speed)
cruise control mode.
This mode allows driving at a speed be-
tween 25 to 90 mph (40 to 144 km/h) with-
out keeping your foot on the accelerator
pedal.

∙ Do not use the conventional (fixedspeed) cruise control mode when
driving under the following
conditions:
– When it is not possible to keep the vehicle at a set speed
– In heavy traffic or in traffic that var- ies in speed
– On winding or hilly roads
– On slippery roads (rain, snow, ice, etc.)
– In very windy areas
∙ Doing so could cause a loss of vehicle control and result in an accident.
