WARNING  

WARNING Always wait until the procedure of shifting 
Always wait until the procedure of shifting from HIGH RANGE to LOW RANGE – and from LOW RANGE to HIGH RANGE – has been entirely completed. During this procedure do not turn off the engine or shift the automatic transmission into another gear.
If you do not wait until the shifting procedure has been entirely completed then it might not be correctly performed. The transfer case might be in neutral, thus interrupting the transfer of power between the engine and the drive axle.
The vehicle is then freely movable, even if a gear has been selected, and could unintentionally be set into motion – particularly on up – or downhill grades. This could lead to an accident and cause injury to yourself and others.
Please observe related messages appearing in the multifunction display.
