Engine overheating
WARNING

Do not remove the radiator cap when the engine and radiator are hot.
Scalding hot fluid and steam may be blown out under pressure, which
could cause serious injury. Be sure to wait until the engine has cooled.
Place a thick rag, like a towel, over the radiator cap, and then slowly ro-
tate the cap counterclockwise to the detent to allow any residual pres-
sure to escape. When the hissing sound has stopped, press down on the
cap while turning it counterclockwise, and then remove the cap.
TIP
If coolant is not available, tap water can be temporarily used instead, provided that
it is changed to the recommended
coolant as soon as possible.
Wait until the engine
has cooled.
Check the coolant
level in the reservoir
and radiator.Add coolant.
(See TIP.)
The coolant level is
OK.
There is no leakage.
There is leakage.
The coolant level is
low.
Check the cooling
system for leakage.

Emergency mode
When the smart key is lost, damaged,
or its battery has discharged, the vehi-
cle can still be turned on and the engine
started. You will need a mechanical key
and the smart key system identification
number. To operate the vehicle in
emergency mode, carry out the follow-
ing steps.
TIP
Emergency mode operation will be
cancelled if the respective steps are not
carried out within the time set for each
operation or if the “OFF/LOCK” switch
is pushed. 1. Stop the vehicle in a safe place.
2. Unlock the seat by inserting the mechanical key into the lock locat-
ed right side of body and turn it
counter clockwise.
3. Open the seat and check that the trunk light comes on.
4. Push the “ON/ ” switch once.
5. Without completely shutting the seat, raise and lower it three times
within 10 seconds.
TIP
Use the rear storage compartment light
as a guide when raising and lowering
the seat. The smart key system indicator
light on the speedometer will come
on for three seconds to indicate
the transition to emergency mode.
6. After the smart key system indica- tor light goes off, use the “ / ”
switch to enter the identification
number.
7. Inputting the identification number is done by counting the number of
flashes of the smart key system in-
dicator light.
For example, if the identification
number is 123456:
Push and hold the “ / ” switch.

The smart key system indicator
light will start to flash.

Storage
Always store the vehicle in a cool, dry
place. If necessary, protect it against
dust with a porous cover. Be sure the
engine and the exhaust system are
cool before covering the vehicle. If the
vehicle often sits for weeks at a time be-
tween uses, the use of a quality fuel
stabilizer is recommended after each
fill-up.
NOTICE
ECA21170
Storing the vehicle in a poorly
ventilated 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.
Long term storage
Before storing the vehicle long term (60
days or more): 1. Make all necessary repairs and perform any outstanding mainte-
nance.
2. Follow all instructions in the Care section of this chapter.
3. Fill up the fuel tank, adding fuel stabilizer according to product in-
structions. Run the engine for 5
minutes to distribute treated fuel
through the fuel system.
4. For vehicles equipped with a fuel cock: Turn the fuel cock lever to
the off position.
5. For vehicles with a carburetor: To prevent fuel deposits from building up, drain the fuel in the carburetor
float chamber into a clean contain-
er. Retighten the drain bolt and
pour the fuel back into the fuel
tank.
6. Use a quality engine fogging oil ac- cording to product instructions to
protect internal engine compo-
nents from corrosion. If engine fog-
ging oil is not available, perform
the following steps for each cylin-
der:
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 spark-
ing during the next step.)
d. Turn the engine over several times with the starter. (This will
coat the cylinder wall with oil.)
WARNING! To prevent dam-
age or injury from sparking,
make sure to ground the
spark plug electrodes while
turning the engine
over.
[EWA10952]
e. Remove the spark plug capfrom the spark plug, and then
install the spark plug and the
spark plug cap.
7. Lubricate all control cables, pivots, levers and pedals, as well as the
sidestand and centerstand (if
equipped).
8. Check and correct the tire air pres- sure, and then lift the vehicle so
that all wheels are off the ground.
