2020 NISSAN SENTRA wheel torque

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.
WARNING
• Never rely solely on the hill start as-
sist system to prevent the vehicle
from moving backward on a hill. Al-
ways drive carefully and attentively.
Depress the brake pedal when the
vehicle is stopped on a steep hill. Be
especially careful when stopped on a
hill on frozen or muddy roads. Failure
to prevent the vehicle from rolling
backwards may result in a loss of
control of the vehicle and possible
serious injury or death.
• The hill start assist system is not de-
signed to hold the vehicle at a stand-
still on a hill. Depress the brake pedal
when the vehicle is stopped on a
steep hill. Failure to do so may cause
the vehicle to roll backwards and
may result in a collision or serious
personal injury.
• The hill start assist system may not
prevent the vehicle from rolling
backwards on a hill under all load or
road conditions. Always be prepared
to depress the brake pedal to prevent
the vehicle from rolling backwards.
Failure to do so may result in a colli-
sion or serious personal injury.

4. Lower the vehicle slowly until the tiretouches the ground. Then, with the
wheel nut wrench, tighten the wheel
nuts securely in the sequence illustrated
(
OA,OB,OC,OD,OE). 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
specification at each lubrication interval. 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 and Loading Information Label.
Af ter adjusting tire pressure to the COLD
tire pressure, the display of the tire pres-
sure information may show higher pres-
sure than the COLD tire pressure af ter
the vehicle has been driven more than 1
mile (1.6 km).
This is because the tire pressurizes as
the tire temperature rises. This does not
indicate a system malfunction.
5. Securely store the flat tire in the vehicle.
6. Install the jack in its storage area and
secure with rubber strap.
7. Place the trunk floor carpeting over the damaged tire.
8. Close the trunk.

CHANGING WHEELS AND TIRES
Tire rotation
NISSAN recommends rotating the tires ev-
ery 7,500 miles (12,000 km).
For additional information on tire replacing
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 tightened
to specifications at all times. It is recom-
mended that wheel nuts be tightened to
specification at each tire rotation inter-
val.
WARNING
• Af ter rotating the tires, check and ad-
just 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 regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.
