Cold Drive-Away Function; Speedometer/Tachometer/Digital Gauge - Yamaha SRS10ML53 Owner's Manual


NOTE: Before starting the snow-
mobile in extremely cold tempera-
tures, the drive belt should be
removed and warmed up to room
temperature. Once the drive belt is
at room temperature, install the
drive belt.
CAUTION
Never run the engine with the drive
belt removed. Excessive revving of
the engine could result in serious
engine damage and drive clutch
failure.

Cold Drive-Away Function

On these models, there is a "cold drive-
away" function incorporated within the
ECM.
When cold-starting the engine, the cool-
ant temperature warning icon will illumi-
nate and the LOW TEMP display on the
readout screen will begin to flash. With
the engine in this temperature range, the
RPM "limit" of the engine will be below
drive system engagement speed. As the
engine warms, the coolant temperature
warning icon will begin to flash, the
TEMP display will continue to flash, and
the RPM "limit" of the engine will
increase allowing the snowmobile to
move without full-throttle operation.
When the engine reaches proper operat-
ing temperature, the coolant temperature
warning icon and the LOW TEMP dis-
play will go out.
CAUTION
It is extremely important that the
engine is properly warmed up before
subjecting the engine to high speed
operation or heavy loads. The engine
should be allowed to idle at least 3-4
minutes before it is operated at more
than 1/2 throttle. In extremely cold
conditions, the warm-up time will be
longer. Cold seizure and piston scuff-
ing caused by insufficient warm-up
will not be covered by warranty. Also,
do not idle the engine for excessively
long periods of time.

A. Coolant Temperature Indicator
The indicator and LOW TEMP display
will cease to flash when the engine
reaches proper operating temperature.
If the coolant temperature rises too far
above proper operating temperature, the
indicator will flash a warning (alert) and
the engine will "surge" to alert the opera-
tor. If the coolant temperature rises to a
critical point above proper operating tem-
perature, the indicator will cease flashing
and will remain constantly illuminated.

NOTE: If the indicator is con-
stantly on, the engine will shut off if
vehicle speed is reduced to 1.5 km-
h (0.9 MPH) or slower.
CAUTION
If the indicator is illuminated, stop the
engine immediately and allow it to
cool down. If unable to either deter-
mine or remedy the problem, take the
snowmobile to an authorized Yamaha
Snowmobile dealer for service. If not
under warranty, this service is at the
discretion and expense of the snow-
mobile owner.
B. High Beam Indicator
The indicator is on whenever the high
beam mode is selected by the headlight
switch.
C. Oil Pressure Indicator
The indicator relates to engine oil pres-
sure, not the oil level; however, if the oil
level is low, it may affect oil pressure. If
oil pressure is lost, check the oil level
(see page 22).
