When jump-starting, obser
vethefo llowing points:
R The battery is not accessible in all vehicles. If
th eot her vehicle's battery is not accessible,
starting assis tance is tobe pr ovided using a
donor battery or a starting assistance device.
R You may only jump-start theve hicle when the
engine and exhaust system are cold.
R Ifth e battery is frozen, do not start theve hicle.
Let the battery thaw /rst.
R Starting assis tance may only be pr ovided using
batteries with a nominal voltage of 12 V.
R Only use jump leads that ha vea su1cient
cross-section and insulated term inal clamps.
R Ifth e battery is fully dischar ged, attach the
donor battery for a few minutes before
attem pting tostart. This charge sth e dis-
ch arge d battery a little.
R Make sure that the two vehicles do not touch.
Jump leads and fur ther information rega rding start-

Ensure thefo llowing before connecting the jump
lead:
R The jump leads are not damaged.
R Parts of thete rm inal clamps which are not
insulated do not come into contact with other
