Safety is one of the biggest reasons buyers consider the Tata Harrier. The SUV has earned a 5-star Bharat NCAP safety rating, making it one of the safest models in its class. On higher variants, Tata also offers ADAS Level 2+, an advanced driver assistance system designed to make everyday driving safer and less stressful.

If you are wondering what ADAS Level 2+ actually means, which Harrier variants get it, or how it differs from the standard ADAS Level 2 package, this guide explains everything you need to know.

What is ADAS Level 2+?

ADAS stands for Advanced Driver Assistance System. It combines cameras, radar sensors, and intelligent software to monitor the road ahead, nearby vehicles, cyclists, pedestrians, and lane markings. Depending on the situation, it can warn the driver or provide steering and braking assistance to help reduce the risk of an accident.

Tata offers three progressively more advanced driver assistance packages across the Harrier range, including ADAS, ADAS Level 2 and ADAS Level 2+. 

The standard ADAS package introduces essential driver assistance features such as Adaptive Cruise Control (automatic variants), Forward Collision Warning and other core safety technologies before progressing to the more advanced Level 2 and Level 2+ systems.

ADAS Level 2 includes core driver assistance features such as:

• Lane Keep Assist
• Lane Departure Warning
• Autonomous Emergency Braking
• Forward Collision Warning
• Blind Spot Detection
• Rear Cross Traffic Alert
• High Beam Assist
• and several other safety functions.

ADAS Level 2+ builds on this package by adding Intelligent Speed Assist, which uses both navigation map data and traffic sign recognition to detect changing speed limits. It also expands the overall functionality of the system, giving the vehicle greater awareness of its surroundings and providing more comprehensive assistance during highway and city driving.

Although ADAS can intervene in certain situations, it is important to remember that it is not an autonomous driving system. The driver remains responsible for steering, braking, and staying alert at all times. Think of ADAS as an additional layer of safety that supports the driver rather than replacing attentive driving.

Which Tata Harrier Variants Get ADAS Level 2+?

Not every Harrier variant comes with ADAS. Tata introduces the technology only on higher trims.

Tata offers the Harrier with three levels of driver assistance technology.

Adventure X+ introduces the basic ADAS package, including Adaptive Cruise Control (automatic variants) and 12 other driver assistance functions.

Fearless X continues with the ADAS package, while Fearless X+ upgrades it to ADAS Level 2, adding Lane Keep Assist, Autonomous Emergency Braking, Forward Collision Warning and several additional driver assistance features.

The range-topping Fearless Ultra and its special editions receive ADAS Level 2+, which further adds Intelligent Speed Assist based on map data and traffic sign recognition, along with additional functionality.

Full List of Tata Harrier ADAS Level 2+ Features

Rather than relying on a single camera or sensor, the Harrier’s ADAS Level 2+ system combines multiple technologies that work together to monitor the vehicle’s surroundings and assist the driver in different situations. Here is the complete feature list, grouped by function.

Instead of relying on just one safety feature, the Harrier’s ADAS Level 2+ suite continuously monitors different aspects of your surroundings. The various systems work together to help detect potential hazards, keep the SUV centred within its lane, warn about vehicles hidden in blind spots, and even apply the brakes automatically when necessary.

How ADAS Level 2+ Helps in Everyday Driving

ADAS makes the biggest difference in situations that drivers encounter every day rather than in rare emergencies. Here is how some of the key features can help on Indian roads.

Highway driving

Adaptive Cruise Control automatically maintains a safe distance from the vehicle ahead by adjusting the Harrier’s speed without constant throttle and brake inputs. During long journeys, this reduces driver fatigue and makes cruising more relaxed.

Intelligent Speed Assist reads both navigation data and roadside speed limit signs, helping drivers stay aware when speed limits change unexpectedly.

City traffic

Stop-and-go traffic can be unpredictable, especially when motorcycles or pedestrians suddenly enter your path. Forward Collision Warning alerts the driver, while Autonomous Emergency Braking can intervene if the driver fails to react in time.

Door Open Alert is particularly useful in busy urban areas. It warns occupants if a cyclist or another vehicle is approaching before the door is opened, helping avoid a common type of city accident.

Long-distance journeys

Driver fatigue often leads to gradual lane drifting. Lane Departure Warning alerts the driver when the vehicle begins to leave its lane without signalling, while Lane Keep Assist and Lane Centreing System gently help guide the SUV back towards the centre of the lane.

These features are especially useful during long highway trips where concentration naturally decreases over time.

Lane changes and reversing

Blind Spot Detection and Blind Spot Monitoring watch areas that are difficult to see through the mirrors. Rear Cross Traffic Alert warns about approaching vehicles when reversing out of a parking space, making busy parking lots much safer.

Night driving

High Beam Assist automatically switches between high and low beam depending on surrounding traffic. This improves visibility while reducing glare for oncoming vehicles, allowing drivers to focus more on the road.

Unlike individual safety features that operate only occasionally, ADAS Level 2+ continuously works in the background throughout most journeys. The combined effect of these technologies makes driving safer, more comfortable, and less tiring without taking control away from the driver.

Who should choose the Harrier ADAS Level 2+ variants?

If you regularly drive on highways, commute long distances or frequently travel with family, ADAS Level 2+ is worth considering. Features like Adaptive Cruise Control, Lane Keep Assist and Blind Spot Monitoring reduce driver fatigue and provide an additional layer of safety during everyday driving. Buyers who mostly drive short city distances may find the standard safety package sufficient.

Beyond ADAS: Other Tata Harrier Safety Features

While ADAS Level 2+ is the Harrier’s headline safety feature, the SUV’s overall safety package goes much further. Tata has combined a strong body structure with active safety technologies and occupant protection systems to make the Harrier one of the safest SUVs in its segment.

Some of the key safety features include:

• 5-star Bharat NCAP safety rating, reinforcing the Harrier’s reputation as one of the safest SUVs available in India.
• Up to 7 airbags, with 6 airbags offered as standard across the range. Higher variants add a driver knee airbag for extra protection.
• Advanced Electronic Stability Program (ESP) with Driver Doze-off Alert on Adventure X+ and higher variants, helping maintain stability during emergency manoeuvres while also monitoring signs of driver fatigue.
• Electronic Parking Brake (EPB) with Auto Hold and Trail Hold, making hill starts and stop-and-go traffic more convenient while preventing the vehicle from rolling backwards.
• Hill Assist and Hill Descent Control, which improve confidence when driving on steep inclines or downhill sections.
• Quad Disc Braking on Adventure X+ and above for stronger and more consistent braking performance.
• Tyre Pressure Monitoring System (TPMS), which alerts the driver when tyre pressure drops below the recommended level.
• 360-degree Surround View Camera with Blind View Monitor, providing a clearer view around the SUV while parking or manoeuvring in tight spaces.
• Emergency Call and Breakdown Call Assist, available in select cities, allowing occupants to quickly connect with assistance if required.
• Corner Stability Control, Roll Over Mitigation, Brake Disc Wiping, Panic Brake Alert, and After Impact Braking, all of which work quietly in the background to improve vehicle stability and braking performance during emergency situations.
• ISOFIX child seat anchorages and 3-point ELR seatbelts with seatbelt reminders for all occupants, helping improve passenger safety on every journey.

This combination of passive safety (body structure, airbags and seatbelts) and active safety (ADAS, braking and stability systems) is what gives the Tata Harrier its strong safety credentials.

A Quick Note on ADAS

ADAS is designed to assist the driver, not replace them.

Although features like Autonomous Emergency Braking, Lane Keep Assist and Adaptive Cruise Control can intervene in certain situations, they cannot anticipate every road condition. Heavy rain, dense fog, faded lane markings, dirty camera lenses, poor visibility or obstructed traffic signs can all affect how accurately the system performs.

Drivers should always keep both hands on the steering wheel, remain attentive, and be prepared to take control whenever necessary. ADAS works best as an additional layer of safety rather than an autonomous driving system.

Our Verdict

The Tata Harrier offers one of the most comprehensive safety packages in the midsize SUV segment, combining a 5-star Bharat NCAP rating with one of the most advanced ADAS suites available in its class. Even the lower variants offer six airbags, Hill Assist and a strong safety package, while Adventure X+ and above add Advanced Electronic Stability Program (ESP) with Driver Doze-off Alert, Quad Disc Braking and other advanced safety technologies. 

If ADAS Level 2+ is your priority, the Fearless Ultra is the entry point. Buyers looking for ADAS Level 2 can consider the Fearless X+. 

Ultimately, ADAS should not be the only reason to buy the Harrier, but it certainly strengthens an already impressive safety package. Combined with its strong crash-test credentials and extensive list of active and passive safety features, the Harrier remains one of the safest family SUVs currently on sale in India.
