nosis device for various electrical cir-
cuits.
If any of those circuits are defective, the
engine trouble warning light will come
on, and then the multi-function display
will indicate a two-digit error code (e.g.,
11, 12, 13).
If the multi-function display indicates
such an error code, note the code num-
ber, and then have a Yamaha dealer
check the vehicle.
CAUTION:

If the display indicates an error
code, the vehicle should be checked
as soon as possible in order to avoidengine damage.
This model is also equipped with a self-
diagnosis device for the immobilizer
system.If any of the immobilizer system circuits
are defective, the immobilizer system
indicator light will flash, and then the
multi-function display will indicate a
two-digit error code (e.g., 51, 52, 53)
when the key is turned to “ON”.
NOTE:If the multi-function display indicates er-
ror code 52, this could be caused by
transponder interference. If this errorappears, try the following.
1. Use the code re-registering key to
start the engine.NOTE:Make sure there are no other immobi-
lizer keys close to the main switch, and
do not keep more than one immobilizer
key on the same key ring! Immobilizer
system keys may cause signal interfer-
ence, which may prevent the enginefrom starting.
2. If the engine starts, turn it off, and
try starting the engine with the
standard keys.

Use only unleaded gasoline. The use
of leaded gasoline will cause severe
damage to internal engine parts,
such as the valves and piston rings,as well as to the exhaust system.
Your Yamaha engine has been de-
signed to use premium unleaded gaso-
line with a research octane number of
95 or higher. If knocking (or pinging) oc-curs, use a gasoline of a different
brand. Use of unleaded fuel will extend
spark plug life and reduce maintenance
costs.
