Locate Suspension Levelling Valve
First of all you need to locate the suspension levelling valve, which is a rocker switch located on the dashboard of the vehicle. The rocker switch has two portions with 'Raise' printed on the upper portion and 'Lower' printed on the lower portion. Make sure you have disconnected the vehicle from performing either function. The safety of the vehicle, freight and most importantly the driver is essential, so take good care of this aspect while performing this function. Also, do not adjust the vehicle level if you are not going to use it for a while, or leave the vehicle unattended for any reason, which can risk a security and safety issue. Make sure you lock your vehicle before you leave as the rocker switch is not accessible to any unconcerned person. -
