NEW DELHI: Tata describes the Sierra's Horizon View cabin setup as a triple-screen experience with 30.48 cm infotainment and passenger screens. Its official feature presentation also lists wireless gaming-controller and headphone compatibility. Owners should check the equipment fitted to their exact variant and request a stationary demonstration before trying the passenger entertainment functions.
| Sierra feature in Tata's presentation | Published detail |
|---|---|
| Infotainment and passenger displays | 30.48 cm screens |
| Passenger entertainment | Gaming, streaming and browsing through Arcade |
| Wireless accessories | Gaming controller and headphones |
| Theater Pro relaxation themes | Fire, Water and Space |
| Equipment availability | Varies across variants and specifications |
Start with the screen in front of the passenger
The useful first question is which functions the passenger can operate independently in the delivered vehicle. Ask the demonstrator to identify the passenger display, the central infotainment display and the driving-information area. Then have the passenger repeat the demonstration while the car remains parked.
This is an especially relevant handover exercise for the Sierra because its cabin presentation brings several entertainment functions together. A family might want navigation available to the driver while a passenger listens privately or uses another screen. Explain that intended use and ask the demonstrator to show what the fitted system actually permits.
Bring the accessories you expect to use, if available, and ask for a compatibility demonstration. Tata's presentation names wireless controllers and headphones but does not provide a universal compatibility list on that page. Record the model of any accessory successfully demonstrated, rather than assuming every device with a similar description will work.
Ask about apps and access separately
Arcade's advertised activities cover gaming, streaming and browsing. Ask which apps are present on your vehicle, what connection each needs and whether access involves a separate subscription or account. These are questions to resolve during handover, not a claim that Tata includes every service or subscription.
If a feature is shown using a demonstrator's phone or account, ask how the same task will be performed with the owner's setup. Keep the discussion focused on an activity you intend to use. A successful demonstration of the home screen alone does not answer whether a particular passenger activity is ready.
For readers comparing cabin equipment across SUVs, our EV battery rental explained: BaaS prices for Punch.ev, Syros EV, Creta, BE 6 illustrates why the exact version matters. Keep each vehicle's equipment and controls attached to its own documentation when making a family handover checklist.
Give audio its own demonstration
Tata's Sierra presentation lists a SonicShaft soundbar, JBL Black speaker system, Harman AudioworX settings and personalised audio for driver and co-driver. Ask to hear how the settings work in the vehicle supplied, with both front occupants seated. Start at a comfortable volume and identify how to return to the previous setting.
Use a familiar piece of audio for the demonstration so that changing settings is easier to follow. Ask where volume and source controls sit, then repeat the basic actions yourself. This is a practical familiarisation method, rather than a review of sound quality or an independent performance test.
Theater Pro's named relaxation themes are another feature to inspect while parked. Ask how to enter and leave the mode, which controls it changes and how to restore the normal cabin setup. Keep that walkthrough separate from preparing navigation for the next journey.
Save the relevant instruction with the vehicle documents so another regular passenger can follow the same controls walkthrough later. That makes the handover useful beyond the person who attended it.
Match the demonstration to the delivered car
Tata qualifies its presentation by saying that shown equipment and accessories can vary by variant and specification. Keep a written list of the functions demonstrated on the actual vehicle. If something is unavailable, ask whether it is absent from that grade or requires further setup, and request the relevant official instruction.
Our Tata Aeris introductory prices span Rs 5.29 lakh to Rs 9.74 lakh and Tata.ev prices: Tiago.ev from Rs 6.99 lakh, Nexon.ev offers up to Rs 1.41 lakh provide related family-SUV reading.

The same Tata presentation specifies 12 speakers in the JBL Black system, 18 JBL Black audio modes and 5.1 Dolby Atmos. It also identifies the iRA Connected Car App with 5G connectivity and describes a total of 75 connected features.
For the cabin's glass area, Tata publishes Panoramax sunroof dimensions of 1,525 mm by 925 mm and identifies voice assistance for that panoramic roof. The feature presentation dates Shailesh Chandra's launch address to November 24, 2025, and identifies him as CEO and Managing Director of Tata Motors Passenger Vehicles.
