Safety information
WARNING
Improperly executed work in the
engine compartment can damage
vehicle components and impair
vehicle functions. There is a risk
of an accident and damage to
property. Have work in the engine
compartment performed by your
Toyota dealer.
WARNING
The engine compartment accom-
modates moving components.
Certain components in the engine
compartment can also move with
the vehicle switched off, for
instance the radiator fan. There is
a risk of injury. Do not reach into
the area of moving parts. Keep
articles of clothing and hair away
from moving parts.

3065-1. MOBILITY
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.
Additional information:
For an overview, refer to page
298.

lid.
5 The coolant level is correct
when it is just below the max-
imum mark in the filler neck.
Safety information
WARNING
With the engine hot and the cool-
ing system open, coolant can

rect additives can damage the
engine. There is a risk of injury
and risk of damage to property.
