Should you notice that the bonnet is not  
safely secured when the vehicle is moving,  
stop the vehicle immediately and close the  
bonnet. Failure to follow this instruction  
could result in an accident.  
CAUTION  
To avoid damage to the bonnet and to the  
windscreen wiper arms, only open it when  
the windscreen wipers are in place against  
the windscreen.
