According to my Autodata manual around 2002 they changed from drum brakes to discs for the rear/handbrake, so obviously advise is different.
In general terms and others may give more specific advise, but if it is rear brake discs and pads, then all you can do is make sure there is plenty of material on the brake pads and that the handbrake lever where it is on the brake caliper is in it's full off position against it's stop ( often calipers start to seize and the lever doesn't full retract so preventing automatic adjustment) so if it is against it's stop then it should be possible to adjust the cable usually where n/s and o/s cables meet there will be a cable adjuster with a lock nut which may want oiling. Do not over adjust the cable as it will have the same effect as a sticking caliper and stop correct adjustment as well as causing brake drag.
If yours is the earlier drum rear brake handbrake operation personally when servicing drum brakes I was taught to always adjust at the drum even where automatic adjusters were fitted before adjusting any cables, always being careful not to cause any brake drag. This way you keep the optimum leverage efficiency, however if you are not sure, it may be safer to just nip up the cable adjuster slightly as without experience it is easy to over tighten the adjusters and cause brake drag.
Which ever you do I would advise afterwards a short roadtest and then jack the vehicle up safely and check the wheels spin freely with no drag , just in case you get over enthusiastic.
