MARUTI SUZUKI Swift 2024 Manual

INTRODUCTION TO CNG

NOTE:

• As per Government regulation, CNG cylinder needs to be checked and certified every THREE (3) YEARS from the date of initial testing as mentioned on the CNG cylinder identification plate. Customer has to present the vehicle to a government approved testing agency.
