Safety precautions:
Never allow any part of your body to be under the vehicle when it is supported only by the exhaust jack 
Be aware that vehicle's exhaust fumes are poisonous if inhaled in large quantities 
Therefore do not use the exhaust jack in a confined area and always turn off engine when not inflating the jack 
Always chock both front and rear wheels opposite to the side under which the jack is being used and apply the handbrake 
When placing the exhaust jack under the vehicle, ensure the bag is away from hot or sharp underbody pares and clear away sharp sticks from the ground 
It is essential to use the protective mats provided to help to prevent puncturing the bag 

Do not over-inflate the bag, 90% capacity is ample
