EXPLANATION OF COMPONENTS
DEF LEVEL GAUGE
The DEF level gauge indicates the remaining level of DEF.
If the indicator is in green range during operation, it is normal.
If the indicator comes close to (A) of red range during opera-
tion, check and add DEF.
(A) to (B): Red range
(A) to (C): Green range
When the indicator is in red range from (A) to (B), the DEF lev-
el caution lamp (1) lights up in red.
If DEF level further decreases after the lamp lights up in red,
the engine output power and engine speed are limited. For de-
tails, see "HANDLE UREA SCR SYSTEM WARNING (3-128)".
When remaining level of DEF cannot be detected, the DEF level caution lamp (1) lights up in white.
REMARK
•
Immediately after turning the starting switch to ON position and while the engine is running, the DEF level
caution lamp (1) lights up in white. However, this does not indicate abnormality.
•
In cold weather, DEF level cannot be detected and the DEF level caution lamp (1) lights up in white for ap-
proximately 1 hour. However, this does not indicate abnormality.
•
Even if the DEF level caution lamp (1) is not lit in white, it may take a long time for the DEF level gauge to
display the correct position.
Note that the following cases are not abnormal:
•
When DEF is added while the starting switch is kept at ON position.
•
When the starting switch is turned to ON position immediately after adding DEF (within approximately
30 seconds).
Before adding DEF, turn the starting switch to OFF position. Wait for a while after adding, then turn the
starting switch to ON position.
FUEL CONSUMPTION MONITOR
The fuel consumption monitor displays the mean value of the
fuel consumption of 1 minute after the starting switch is turned
to ON position.
•
The rightmost gauge (N) shows the latest value. The for-
mer values of 1 minute are displayed subsequently to the
left.
•
When the orange graph reaches the top (M) of the gauge,
it shows 50 ℓ/h. The intermediate white line (W) shows the
guide line of 30 ℓ/h.
•
Every time when the starting switch is turned to ON posi-
tion from OFF position, the graph is cleared.
HYBRID TEMPERATURE GAUGE
The hybrid temperature gauge indicates the temperature of hy-
brid components.
If the indicator is in green range during operation, it is normal.
If the indicator goes beyond the red range (A) during opera-
tions, the overheat prevention system operates.
(A) to (B): Red range
(A) to (C): Green range
(C) to (D): White range
