Temperature Gauge
When the ignition switch is
in the "ON" position, this
LED indicates the engine
coolant temperature. The indicator
should be within the normal, acceptable
temperature range i.e. between "H" and
"C". If the indicator approaches "H",
overheating is indicated by a RED bar.
If the coolant temperature reading is
very high, the warning tell-tale flashes
with an audible buzzer. In this case, stop
the vehicle, switch 'OFF' the engine and
cool it down for some time. Contact a
nearest TATA MOTORS Authorized Ser-
vice Centre immediately for rectification.
NOTE
At every key in and Ignition ON,
Temperature Gauge Bars move to
H and come back to C position.
This is welcome strategy and self-
check feature.
WARNING
 The red progress bar indicates
over heating due to high coolant
temperature that may damage
the engine. If you continue to
drive the vehicle in this case, it
can result in severe engine dam-
age or even fire.
 Never remove the radiator pres-
sure cap from the radiator when
the engine is hot. Do not restart
the engine until the problem has
been duly attended.
