Here is a recent video, which explains the whole process to fill diesel exhaust fluid in the new-gen Tata Safari and Harrier.

Almost every diesel engine offered in our market comes with DEF (Diesel Engine Fluid). Diesel exhaust fluid is a liquid, which is used to reduce the amount of air pollution made by oil burners. DEF is a watery solution of 32.5 per cent Urea and 67.5 per cent deionized water. The diesel exhaust fluid is consumed by selective catalytic reduction (SCR), which decreases the concentration of nitrogen oxide (NOx) in diesel exhaust emissions coming from a diesel mill. SUVs like 2021 Safari and Harrier are also offered with DEF. Here’s a recent video, which shows the filling procedure and guidelines of DEF in both Tata SUVs.

This video has been uploaded by a YouTube channel named Power Stroke PS. The DEF gauge is positioned on the bottom left side of the fuel gauge. The new-gen Tata Safari and Harrier have a DEF tank capacity of 15-litres. Before filling the DEF tank, park the car on flat ground, stop the engine and engage the parking brake. Tata offers diesel engine fluid in 2-litre, 5-litre and 10-litre bucket. Start by cutting the seal with a sharp cutter or pocket knife and pull out the cup head to open it. Connect the hose with the bucket in such a way that the hose points outwards. Afterwards, open the booth of the vehicle and then open the DEF filling cap, which is placed on the left corner of the boot.

Then insert the hose in the DEF filling neck without spilling. After filling the DEF tank, close it with the DEF tank cap and close the boot. Make sure that the ignition is off while topping-up the DEF. Clean the DEF tank cap and surroundings before opening. Always try to maintain at least 25 per cent diesel engine fluid in the tank. Both SUVs are powered by a 2.0-litre Kryotec diesel engine, which develops 168bhp of power and 350 Nm of torque. The engine comes paired with a 6-speed MT or a 6-speed torque converter automatic gearbox.
