Q & A

What is the function of the knock sensor in a car?

The knock sensor detects engine knock, which is premature or uneven fuel ignition, and instantly adjusts ignition timing to prevent damage to the pistons, connecting rods, and engine block.

How do automatic headlight washers improve driving safety?

They keep headlights clean by activating when dirty and on, ensuring optimal brightness. This improves visibility at night or in harsh weather, reducing reaction time and accident risk.

What is the purpose of timed air recirculation mode?

Timed air recirculation mode automatically switches from recirculated to fresh air after a set period, maintaining cabin air quality, blocking odors and pollutants, and improving health and AC efficiency.

How do smart autofolding mirrors protect a car?

They automatically fold at low speeds or when parking in tight spots, reducing the risk of scratches, breakage, and accidental contact with pedestrians or cyclists.

What are programmable horn patterns and how are they useful?

Programmable horn patterns allow multiple tones and rhythms to convey different messages, such as a polite alert or urgent warning, enhancing communication while driving.

How does the memory for three recent cruise control speeds benefit drivers?

It allows drivers to quickly switch between three previously used speeds, saving time and reducing the need to readjust cruise control when driving in areas with varying speed limits.

What does the steering wheel control learning mode do?

This mode allows the driver to reprogram steering wheel buttons to control new devices, such as aftermarket entertainment systems, without visiting a shop.

How does the auto-stop window safety feature prevent injury?

It detects resistance when a window is closing, even as light as 4 pounds, and reverses to prevent pinching, protecting passengers and avoiding window damage.

What is the benefit of the special hazard light mode?

By pressing the hazard button three times quickly, the car activates a faster flashing pattern, making the vehicle more visible in roadside emergencies and reducing the risk of rear-end collisions.

Why is it important to reset the tire pressure sensor after inflating tires?

Resetting the sensor registers the new pressure levels as the baseline, preventing false warnings and avoiding unnecessary diagnostic fees or missed dangerous tire issues.

How does climate control habit memory improve comfort?

It learns the driver’s preferred temperature adjustments based on habits and external conditions, automatically setting the ideal cabin climate without manual input.

What is the purpose of enhanced reverse lighting?

Enhanced reverse lighting increases brightness and activates side or puddle lights when reversing, improving visibility and helping drivers spot obstacles or pedestrians at night.
