Nissan Altima (L34) 2019-2024 Owners Manual: Chassis Control (if so equipped)

The chassis control is an electric control module that includes the following functions:

• 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 information, see "Vehicle information display - 5 inch (13 cm) Type A" or "Vehicle information display - 7 inch (18 cm) Type B".

When the VDC system is turned off, the I-TC is also turned off.

WARNING

The I-TC may not be effective depending 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 example, 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 comfort in effort to restrain uncomfortable upper 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 operating properly.
