TIP
If the low battery indicator comes on,
check and recharge the battery as nec-
essary. (See page 6-32.)
Warning and service messages
This function works in conjunction with
fuel meter, coolant temperature meter,
oil change indicator, and low battery

Starting the engine
In order for the ignition circuit cut-off
system to enable starting, one of the
following conditions must be met:
The transmission is in the neutral
position.
The transmission is in gear with
the clutch lever pulled and the
sidestand up.
See page 3-20 for more informa-
tion.
1. Turn the key to “ON” and make
sure that the engine stop switch is
set to “ ”.
The following warning lights and
indicator lights should come on for
a few seconds, then go off.
Neutral indicator light
Turn signal indicator light
High beam indicator light
Engine trouble warning light
Fuel level warning light
Tachometer high-rpm warn-
ing light
NOTICE
ECA11834
If a warning or indicator light does
not come on initially when the key is
turned to “ON”, or if a warning or in-
dicator light remains on, see page
3-2 for the corresponding warning
and indicator light circuit check.
The ABS warning light should
come on when the key is turned to
“ON”, and then go off after travel-
ing at a speed of 10 km/h (6 mi/h)
or higher.
NOTICE
ECA17682
If the ABS warning light does not
come on and then go off as ex-
plained above, see page 3-2 for the
warning light circuit check.
2. Shift the transmission into the
neutral position. The neutral indi-
cator light should come on. If not,
ask a Yamaha dealer to check the
electrical circuit.
3. Start the engine by pushing the
start switch.
If the engine fails to start, release
the start switch, wait a few sec-
onds, and then try again. Each
starting attempt should be as
short as possible to preserve the
battery. Do not crank the engine
more than 10 seconds on any one
attempt.
NOTICE
ECA11043
For maximum engine life, never ac-
celerate hard when the engine is
cold!

Checking the wheel bearings
The front and rear wheel bearings must
be checked at the intervals specified in
the periodic maintenance and lubrica-
tion chart. If there is play in the wheel
hub or if the wheel does not turn
smoothly, have a Yamaha dealer
check the wheel bearings.
EAU23315
Battery
A poorly maintained battery will cor-
rode and discharge quickly. The elec-
trolyte level, battery lead connections
and breather hose routing should be
checked before each ride and at the in-
tervals specified in the periodic mainte-
nance and lubrication chart.
WARNING
EWA10771
Electrolyte is poisonous and
dangerous since it contains sul-
furic acid, which causes severe
burns. Avoid any contact with
skin, eyes or clothing and al-
ways shield your eyes when
working near batteries. In case
of contact, administer the fol-
lowing FIRST AID.
EXTERNAL: Flush with plenty
of water.
INTERNAL: Drink large quan-
tities of water or milk and im-
mediately call a physician.
EYES: Flush with water for 15
minutes and seek prompt
medical attention.
Batteries produce explosive hy-
drogen gas. Therefore, keep
sparks, flames, cigarettes, etc.,
away from the battery and pro-
vide sufficient ventilation when
charging it in an enclosed
space.
Take care not to spill electrolyte
on the drive chain, as this may
weaken it, shorten chain life and
possibly result in an accident.
KEEP THIS AND ALL BATTER-
IES OUT OF THE REACH OF
CHILDREN.

6 To check the electrolyte level
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion.
TIP
Make sure that the vehicle is posi-
tioned straight up when checking the
electrolyte level.
2. Check the electrolyte level in the
battery.
TIP
The electrolyte should be between the
minimum and maximum level marks.
3. If the electrolyte is at or below the
minimum level mark, add distilled
water to raise it to the maximum
level mark. NOTICE: Use only
distilled water, as tap water
contains minerals that are
harmful to the battery.
[ECA10612]
4. Check and, if necessary, tighten
the battery lead connections and
correct the breather hose routing.
To store the battery
1. If the motorcycle will not be used
for more than one month, remove
the battery, fully charge it, andthen place it in a cool, dry place.
NOTICE: When removing the
battery, be sure the key is
turned to “OFF”, then discon-
nect the negative lead before
disconnecting the positive lead.
[ECA16303]
2. If the battery will be stored for
more than two months, check the
specific gravity of the electrolyte
at least once a month and fully
charge the battery whenever nec-
essary.
3. Fully charge the battery before in-
stallation. NOTICE: When install-
ing the battery, be sure the key
is turned to “OFF”, then connect
the positive lead before con-
necting the negative lead.
[ECA16841]
4. After installation, make sure that
the battery leads are properly con-
nected to the battery terminals
and that the breather hose is prop-
erly routed, in good condition, and
not obstructed. NOTICE: If the
breather hose is positioned in
such a way that the frame is ex-
posed to electrolyte or gas ex-
pelled from the battery, the
frame could suffer structural
and external damages.
