to the coolant reservoir until the
coolant level is between the MIN and
MAX marks on the reservoir.
Whenever you add coolant, check the
coolant level in the coolant reservoir the
next few times you drive the vehicle. If
necessary, add prediluted coolant to bring
the coolant level to the proper level.
If you have to add more than 1 qt (1 L) of
coolant per month, have your dealer check
the cooling system. Your cooling system
could have a leak. Operating an engine
with a low level of coolant can result in
engine overheating and engine damage.
