CAB DOORS AND DOOR LOCK
DANGER
To lessen the chance of being thrown
from the vehicle in case of an accident,
always lock the doors and wear the safety
belt while driving. Failure to do so can
cause serious personal injury or death if
involved in an accident.
The cab doors can be unlocked and locked with the same key used for the ignition lock.
There is also a keyless remote entry available. Keys can be made to fit only one vehicle or
all the vehicles in a fleet of Volvo vehicles. The key fits in the door lock either way. Insert
the key and turn it 1/4 turn counterclockwise to unlock or clockwise to lock the door.
1 Press once to unlock driver side. Press twice to unlock both doors.
