Fuel meter
The fuel meter indicates the amount of
fuel in the fuel tank. The segments of
the fuel meter disappear from “F” (full)
towards “E” (empty) as the fuel level
decreases. When the last segment of
the fuel meter starts flashing, refuel as
soon as possible.
TIP If a problem is detected in the fuel
meter, the all segments will flash
repeatedly. If this occurs, have a
Yamaha dealer check the vehicle.
 When approximately 2.3 L (0.61
US gal, 0.51 Imp.gal) of fuel re-
mains in the fuel tank, the last seg-
ment of the fuel meter will start
flashing. The display will automat-
ically change to the fuel reserve
tripmeter “F Trip” and start count-
ing the distance traveled from that
point.Coolant temperature meter The coolant temperature meter indi-
cates the temperature of the coolant.
If the top segment flashes, stop the ve-
hicle, then stop the engine, and let the
engine cool. (See page 8-33.)

sible.
 The coolant temperature varies
with changes in the weather and
engine load.

Anti-lock brake system (ABS)This model’s ABS features a dual elec-
tronic control system, which acts on
the front and rear brakes independent-
ly.
Operate the brakes with ABS as you
would conventional brakes. If the ABS
is activated, a pulsating sensation may
be felt at the brake levers. In this situa-
tion, continue to apply the brakes and
let the ABS work; do not “pump” the
brakes as this will reduce braking ef-
fectiveness.
WARNING
EWA16051
Always keep a sufficient d istance
from the vehicle ahea d to match the
ri din g speed even with ABS.
 The ABS performs b est with
lon g b rakin g d istances.
 On certain surfaces, such as
rou gh or g ravel roa ds, the b rak-
in g d istance may be lon ger with
the ABS than without.The ABS is monitored by an ECU,
which will revert the system to conven-
tional braking if a malfunction occurs.

a d vice on what prod ucts to use be-
fore cleanin g the vehicle. Usin g a

EAU83443
CareFrequent, thorough cleaning of the ve-
hicle will not only enhance its appear-
ance but also will improve its general
performance and extend the useful life
of many components. Washing, clean-
ing, and polishing will also give you a
chance to inspect the condition of the
vehicle more frequently. Be sure to
wash the vehicle after riding in the rain
or near the sea, because salt is corro-
sive to metals.TIP The roads of heavy snowfall areas
may be sprayed with salt as a de-
icing method. This salt can stay on
the roads well into spring, so be
sure to wash the underside and
chassis parts after riding in such
areas.
 Genuine Yamaha care and main-
tenance products are sold under
the YAMALUBE brand in many
markets worldwide.
 See your Yamaha dealer for addi-
tional cleaning tips.
NOTICE

chemicals such as, solvents,

flui d, or antifreeze, etc.
Before washin g
1. Park the vehicle out of direct sun- light and allow it to cool. This will
help avoid water spots.
2. Make sure all caps, covers, elec- trical couplers and connectors are
tightly installed.
3. Cover the muffler end with a plas- tic bag and a strong rubber band.
4. Pre-soak stubborn stains like in- sects or bird droppings with a wet
towel for a few minutes.
5. Remove road grime and oil stains with a quality degreasing agent
and a plastic-bristle brush or
sponge. NOTICE: Do not use
d eg reasin g a gent on areas re-
quirin g lu brication such as
seals, gaskets, an d wheel axles.
Follow pro duct instructions.
[ECA26290]
Washin g
1. Rinse off any degreaser and spray down the vehicle with a garden
hose. Use only enough pressure
to do the job. Avoid spraying wa-
ter directly into the muffler, instru-
ment panel, air inlet, or other inner
areas such as underseat storage
compartments.
2. Wash the vehicle with a quality au- tomotive-type detergent mixed
with cool water and a soft, clean
towel or sponge. Use an old tooth-
brush or plastic-bristle brush for
hard-to-reach places. NOTICE:
Use col d water if the vehicle has
b een exposed to salt. Warm wa-
ter will increase salt’s corrosive
properties.
[ECA26301]
3. For windshield-equipped vehicles: Clean the windshield with a soft
towel or sponge dampened with
water and a pH neutral detergent.
If necessary, use a high-quality
windshield cleaner or polish for
motorcycles. NOTICE: Never use
any stron g chemicals to clean
the wind shield. Additionally,
some cleanin g compoun ds for plastic may scratch the win
d-
shiel d, so b e sure to test all
cleanin g pro ducts before gen-
eral application.
[ECA26310]
4. Rinse off thoroughly with clean water. Be sure to remove all deter-
gent residues, as they can be
harmful to plastic parts.
After washin g
1. Dry the vehicle with a chamois or absorbent towel, preferably mi-
crofiber terrycloth.
2. For drive chain-equipped models: Dry and then lubricate the drive
chain to prevent rust.
3. Use a chrome polish to shine chrome, aluminum, and stainless
steel parts. Often the thermally in-
duced discoloring of stainless
steel exhaust systems can be re-
moved through polishing.
4. Apply a corrosion protection spray on all metal parts including
chrome or nickel-plated surfaces.
WARNING! Do not apply sili- cone or oil spray to seats, han d
g rips, ru bber foot pe gs or tire
trea ds. Otherwise these parts
