NOTICE
■To prevent damage to the engine and its components
●Do not let the indicator needle of the tachometer enter the red zone, which indicates
the maximum engine speed.
●The engine may be overheating if the engine coolant temperature gauge is in the red
zone (H). In this case, immediately stop the vehicle in a safe place, and check the
engine after it has cooled completely. (→P. 5 2 8 )

Engine coolant temperature gauge
Displays the engine coolant temperature. If the engine coolant temperature gauge
indicator ( ) enters the red zone, a buzzer will sound and the indicator will turn red
and start flashing. Also, a warn ing message will be displayed.
Engine oil temperature gauge
Displays the engine oil temperature. If the engine oil temperature gauge indicator
( ) enters the red zone, the indicator will turn red and start flashing.
Outside temperature
Displays the outside temperature within the range of -40°F (-40°C) to 122°F
(50°C). Low outside temperature indicator comes on when the ambient temperature
is 37°F (3°C) or lower.

Eco driving meter
Displays the vehicle acceleration. The more rapidly the vehicle is accelerated, the
lower the number of blue segments displayed, indicating that your driving is less eco-
friendly. This meter is designed as a guid eline to show the eco-friendliness of your
driving.

■The meters and display illuminate when
The engine switch is in IGNITION ON mode.
■Welcome illumination of the analog speedometer
●When the driver’s door is opened, the analog speedometer will illuminate.
Then, when the driver’s door is closed, the analog speedometer will illuminate and go
off (pulsate) 3 times.
●In the following situations, the analog sp eedometer will not pulsate even though the
driver’s door is opened and closed:
• Within 60 seconds after the analog meter pulsation completes
• Within 60 seconds of turning the engine switch off
■Va r i a b l e r e d z o n e
■Eco driving meter
●The number of blue segments displayed on the eco driving meter decreases/increases
depending on the vehicle acceleration. Use th is meter as a guideline when you wish to
drive in an eco-friendly manner that reduces fuel consumption.
However, on a downward grade where the vehicle can accelerate without the acceler-
ator pedal being depressed, the eco driving meter may not display the eco-driving
state correctly.
●When the shift lever is moved to P, N or R, the segments will turn gray and the eco driv-
ing meter will not operate.

To help protect the engine, the engine speed is
controlled by changing the starting position of
the tachometer’s red zone depending on the
engine coolant temperature within a range from
3700 rpm to 7300 rpm.
Before driving under extremely high load condi-
tions, make sure to sufficiently warm up the
engine.

NOTICE
■To prevent damage to the engine and its components
●Do not let the indicator of the tachometer enter the red zone, as it represents the
engine speed range which exceeds the maximum safe engine speed.
●In the following situations, the engine may be overheating. In this case, immediately
stop the vehicle in a safe place, and check the engine after it has cooled completely.
( → P. 5 2 8 )
• The engine coolant temperature gauge indicator ( ) is in the red zone and flash- ing.
• The engine oil temperature gauge indicator ( ) is in the red zone and flashing.

When in the M position, the gear will not change unless the shift lever or paddle
shift switches are operated.
However, even when in the M position, the gears will be automatically changed in
the following situation:
●When vehicle speed drops (downshift only).
●When the automatic transmission fluid or engine coolant temperature is low.
●GS350/GS200t: When automatic transmission fluid temperature is high.
●GS350/GS200t: When the needle of the
tachometer is in the red zone (the
range which exceeds the allowable revs of the engine).
In the following situations, the gear will not shift even if the shift lever or paddle
shift switches are operated.
●“Slippery Road. Cannot Shift to Lower Gear.” is displayed on the multi-infor-
mation display.
●The vehicle speed is low (upshift only).

●Have the vehicle fitted with four snow tires or purchase a set of tire chains for
the rear tires.
*
Ensure that all tires are the specified size and brand, and that chains match the size of
the tires.
*: Tire chains cannot be mounted on vehicles with front and rear tires of differing sizes and vehicles with LDH and 19-inch tires.
●Use fluids that are appropriate to the prevailing outside temperatures.
