EBU18171Horn switch “ ”
Press the switch to sound the horn.EBU18192Override switch “OVERRIDE”
Top speed is normally limited when operating in
differential gear lock. If conditions require more
engine power when riding forward, push and hold this switch to override the differential gear lock
speed limiting function. (See page 4-11.) Releas-
ing the switch restores the speed limiting function.
While the override switch is pushed, the segments
of the speedometer digits will appear as shown in
the figure.
TIPIf the digits of the speedometer appear as shown
when the switch is NOT being pushed, this could
indicate a malfunction in the electrical system. In
this case, take the ATV to a Yamaha dealer at the
first opportunity.
1. Override switch “OVERRIDE”

have a Yamaha dealer check the electrical
circuit.
3. Apply the rear brake lever or brake pedal.
4. Completely close the throttle lever, then push the start switch to crank the engine with the
starter. Release the start switch when the en-
gine has started.
TIPIf the engine fails to start, release the start switch.
Wait a few seconds before the next cranking at-
tempt to allow battery voltage to restore. Do not
crank the engine more than 10 seconds on any
single attempt. NOTICEECB00164For maximum engine life, never accelerate
hard when the engine is cold!

2. Apply the brake pedal, and then shift by mov- ing the drive select lever along the shift guide.TIPMake sure that the drive select lever is completely
shifted into position.

EBU27264StorageShort-term
Always store your ATV in a cool, dry place and, if
necessary, protect it against dust with a porous
cover. NOTICE: Storing the ATV in a poorly ven-
tilated room or covering it with a tarp while it is
still wet, will allow water and humidity to seep
in and cause rust. To prevent corrosion, avoid
damp cellars, stables (because of the presence
of ammonia) and areas where strong chemi-
cals are stored.
[ECB00722]
Long-term
Before storing your ATV for several months: 1. Make any necessary repairs and perform all outstanding maintenance.
2. Follow all the instructions in the Cleaning sec- tion of this chapter.
3. Fill up the fuel tank and add fuel stabilizer (Fu- el Med Rx if available), and then run the en-
gine for 5 minutes to distribute the treated
fuel. 4. Perform the following steps to protect the en-
gine from internal corrosion.a. Remove the spark plug cap and spark plug.
b. Pour a teaspoonful of engine oil into the spark plug bore.
c. Install the spark plug cap onto the spark plug, and then place the spark plug on the
cylinder head so that the electrodes are
grounded. (This will limit sparking during
the next step.)
d. Turn the engine over several times with the starter. (This will coat the cylinder wall
with oil.)
e. Remove the spark plug cap from the spark plug, and then install the spark plug and
the spark plug cap.
5. Lubricate all control cables and the pivoting points of all levers and pedals.
6. Put the frame on stands or blocks to raise all wheels off the ground. (Alternatively, turn the
wheels each month to prevent the tires from
degrading in one spot.)
7. Cover the muffler outlet with a plastic bag to prevent moisture from entering it.
