Routine maintenance and servicing / Battery terminal check (Every 12 000 miles (20 000 km) or 12 months)


Caution: Before carrying out any work on the vehicle battery, read through the precautions given in УSafety first!Ф at the beginning of this manual.

1 The battery fitted as original equipment is Уmaintenance-freeФ, and requires no maintenance apart from having the case kept clean, and the terminals clean and tight.

2 To clean the battery terminals disconnect them, after having first removed the cover (later models) - negative earth first. Use a wire brush or abrasive paper to clean the terminals. Bad corrosion should be treated with a solution of bicarbonate of soda, applied with an old toothbrush. Do not let this solution get inside the battery.

3 Coat the battery terminals with petroleum jelly or a proprietary anti-corrosive compound before reconnecting them. Reconnect and tighten the positive (live) lead first, followed by the negative (earth) lead. Do not overtighten.

4 Keep the top of the battery clean and dry.

Inspect the battery tray for corrosion, and make good as necessary.
