Just had a quick look in the manual and it states the following.
To gain access if replacing a bulb on the right hand side:
Remove the radiator cowl by placing a screwdriver under the four scrivets. Pop the scrivets and remoce the cowl. Undo the battery clamp, remove the battery retaining plate and slide the battery out of the way toward the rear of the vechicle. If the vehicle has a V8 engine and is fitter with a larger battery, the battery terminans must be disconnected, and the battery completely removed from the vehicle.
Note: After replacing the bulb on the right-hand side, remember to replace and connect the battery. Return the cowl to its original position and replace the scrivets.
