2019 NISSAN ALTIMA wheel torque

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.
– During bad weather (rain, fog, snow, dust, etc.)
– When rain, snow, sand, etc., is thrown up by the wheels of other
vehicles
– When dirt, oil, ice, snow, water, or another object adheres to the
camera unit
– When the lens of the camera unit is foggy
– When strong light (for example, sunlight or high beams from on-
coming 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 bright- ness occurs (for example, when the
vehicle enters or exits a tunnel or is
under a bridge)
5-118Starting and driving

∙ When driving on extremely inclinedsurfaces such as higher banked cor-
ners, the VDC system may not operate
properly and the
indicator light
may flash or the
indicator light
may illuminate. Do not drive on these
types of roads.
∙ When driving on an unstable surface such as a turntable, ferry, elevator or
ramp, the
indicator light may
flash or the
indicator light may
illuminate. This is not a malfunction.
Restart the engine af ter driving onto
a stable surface.
∙ If wheels or tires other than the NISSAN recommended ones are used,
the VDC system may not operate
properly and the
indicator light
may flash or the
indicator light
may illuminate.
∙ The VDC system is not a substitute for winter tires or tire chains on a snow
covered road. The chassis control is an electric control
module that includes the following func-
tions:
∙ Intelligent Trace Control
∙ Active Ride Control
INTELLIGENT TRACE CONTROL
(I-TC)
This system senses driving based on the
driver’s steering and acceleration/braking
patterns, and controls brake pressure at
individual wheels to aid tracing at corners
and help smooth vehicle response.
The I-TC can be set to on (enabled) or off
(disabled) through the vehicle information
display “Settings” page. For additional infor-
mation, refer to “Vehicle information dis-
play” in the “Instruments and controls” sec-
tion of this manual.
When the VDC system is turned off, the I-TC
is also turned off.
WARNING
The I-TC may not be effective depend-
ing on the driving condition. Always
drive carefully and attentively. When the I-TC is operating, you may feel a
pulsation in the brake pedal and hear a
noise. This is normal and indicates that the
I-TC is operating properly.
Even if the I-TC is turned off, some functions
will remain on to assist the driver (for ex-
ample, avoidance scenes).
ACTIVE RIDE CONTROL (ARC)
This system senses upper body motion
(based on wheel speed information) and
controls engine torque and four wheel
brake pressure. This will enhance ride com-
fort in effort to restrain uncomfortable up-
per body movement when passing over
undulated road surfaces. This system
comes into effect above 25 mph (40 km/h).
When the VDC system is turned off, the ARC
is also turned off.
When the ARC is operating, you may hear
noise and sense slight deceleration. This is
normal and indicates that the ARC is oper-
ating properly.

Installing the spare tire
The spare tire is designed for emergency
use. For additional information, refer to
“Wheels and tires” in the “Do-it-yourself ”
section of this manual.1. Clean any mud or dirt from the surface between the wheel and hub.
2. Carefully put the spare tire on and tighten the wheel nuts finger tight.
3. With the wheel nut wrench, tighten wheel nuts alternately and evenly in the
sequence illustrated (
A,B,C,D,E)
until they are tight. 4. Lower the vehicle slowly until the tire
touches the ground. Then, with the
wheel nut wrench, tighten the wheel
nuts securely in the sequence illus-
trated (
A,B,C,D,E). Lower the
vehicle completely.
WARNING
∙ Incorrect wheel nuts or improperly tightened wheel nuts can cause the
wheel to become loose or come off.
This could cause an accident.
∙ Do not use oil or grease on the wheel studs or nuts. This could cause the
nuts to become loose.
∙ Retighten the wheel nuts when the vehicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.)
As soon as possible, tighten the wheel
nuts to the specified torque with a
torque wrench.
Wheel nut tightening torque: 83 f t-lb (113 N·m) The wheel nuts must be kept tightened
to specification at all times. It is recom-
mended that wheel nuts be tightened to
specifications at each lubrication inter-
val.
Adjust tire pressure to the COLD pres-
sure.
COLD pressure: Af ter vehicle has been
parked for 3 hours or more or driven less
than 1 mile (1.6 km).
COLD tire pressures are shown on the
Tire Load and Information label affixed
to the driver side center pillar.
5. Securely store the flat tire in the tire well and jacking equipment in the vehicle.
NOTE:
Remove the center wheel cap before
storing the flat tire. 6. Place the spare tire cover and the trunk floor carpeting over the damaged tire.
7. Close the trunk.

CHANGING WHEELS AND TIRES
Tire rotation
NISSAN recommends rotating the
tires every 5,000 miles (8,000 km) for
vehicles equipped with the PR25DD
engine and 7,500 miles (12,000 km)
for vehicles equipped with the
KR20DDET engine.
For additional information on tire re-
placing procedures, refer to “Flat tire”
in the “In case of emergency” section
of this manual.As soon as possible, tighten the
wheel nuts to the specified torque
with a torque wrench.
Wheel nut tightening torque:
83 f t-lb (113 N·m)
The wheel nuts must be kept tight-
ened to specifications at all times.
It is recommended that wheel nuts
be tightened to specification at
each tire rotation interval.
WARNING
∙ Af ter rotating the tires, check and adjust the tire pressure.
∙ Retighten the wheel nuts when the vehicle has been driven for
600 miles (1,000 km) (also in
cases of a flat tire, etc.).
∙ Do not include the spare tire in the tire rotation. ∙ For additional information re-
garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Information”
(Canada) in the Warranty Infor-
mation Booklet.WDI0258
