Irrespective of the warning stages, once DEF level is low, 5.0 liter of
DEF needs to be filled. If the warnings continue even after refill,
contact nearest authorized Mahindra dealer immediately.
In absence of DEF level low warning, refilling is not recommended.
Total DEF quantity inside the DEF Tank should never be more than
20 liter. Overfilling may result in system/component failure. Only
authorized Mahindra dealer will be able to correctly determine
quantity of DEF present inside tank. Hence if you are refilling the
DEF yourself, fill only 5.0 liter, in case DEF Low level warning is
flashed.
If the DEF warning lamp turns on due to the DEF level, refill the
DEF tank. Failure to refill may cause the engine start restriction.
