Boost gauge/engine oil temperature ga uge/engine oil pressure gauge (if
equipped)

Boost gauge
Displays the boost pressure. The
display will change color if the
specified pressure is exceeded.
Engine oil temperature gauge
Displays the engine oil tempera-
ture. The display will flash if the
engine oil temperature exceeds
284 °F (140 °C).
Engine oil pressure gauge
Displays the engine oil pressure. A buzzer will sound an d warning message
will be displayed if the engine oil pressure becomes low. (  P. 460)This display is intended for use as a guideline. Depending on factors such as the
road surface condition, temperature and vehicle speed, the display may not show
the actual condition of the vehicle.

RC350_RC300 AWD_RC3 00_RC F_U(OM24748U)NOTICE ■
When using a high pressure car wash ●
When washing the vehicle, do not spray the camera or its surrounding area directly
with a high pressure washer. Shock appli ed from high pressure water may cause the
device to not operate normally. ●
Do not bring the nozzle tip close to boots (rubber or resin manufactured cover), con-
nectors or the following parts. The parts may be damaged if they come into contact
with high-pressure water.
■
Hood vent (RC F)• Traction related parts
• Steering parts • Suspension parts
• Brake parts●
RC F: Do not point the nozzle of a high pres-
sure washer at the areas shown in the illustra-
tion, as high pressure water may damage the
oil coolers.
When washing the vehicle, do not allow a large
amount of water to enter the hood vent at once,
such as when using a bucket, etc. or point the
nozzle of a high pressure washer at the hood
vent.
Water may get inside the engine compartment
and affect the engine and other components.
