Battery replacementUse approved vehicle batteries only
Only use vehicle batteries that have been
approved for your vehicle by the manufacturer;
otherwise, the vehicle could be damaged and
systems or functions may not be fully availa‐
ble.◀
After a battery replacement, have the battery registered on the vehicle by your service cen‐
ter to ensure that all comfort functions are fully
available and that any Check Control mes‐
sages of these comfort functions are no longer

washers, hold them a sufficient distance away and use a maximum temperature of
140 ℉/60 ℃.
If the vehicle has a glass sunroof, ensure that a distance of at least 31.5 inches/80 cm is main‐
tained. Holding them too close or using exces‐
sively high pressures or temperatures can
