mercially available additives are
suitable for the vehicle. The
vehicle manufacturer recom-
mends using coolant with the
BMW LC-18 specification. Do
not mix additives of different col-
ors. Observe the water - additive
mixture ratio of 50:50. Informa-
tion about suitable additives is
available from your Toyota
dealer.
Depending on the motorization,
there are up to two coolant res-
ervoirs in the engine compart-
ment. Check and top up the
coolant levels on a regular
basis.The coolant may be overfilled in
the coolant reservoir when the
vehicle is delivered from the fac-
tory. The normal coolant level is
achieved by operating the vehi-
cle for a longer period.
The coolant level is indicated
using the maximum mark in the
filler neck of the coolant reser-
voir.
