Four-wheel-drive indicator “”/“”
This indicator comes on when the “2WD”/“4WD”
switch is set to the “4WD” position. The differential
gear lock indicator “DIFF.LOCK” in the four-wheel-
drive indicator also comes on when the “LOCK”-
“4WD” switch is set to the “4WD-LOCK” position.NOTE:_ Due to the synchronizing mechanism in the differ-
ential gear case, the four-wheel drive indicator
may not come on until the vehicle starts moving. _
EVU00181
Coolant temperature warning light “”
When the coolant temperature reaches a specified
level, this light comes on to warn that the coolant
temperature is too hot. If the light comes on during
operation, stop the engine as soon as it is safe to
do so and allow the engine to cool down for about
10 minutes. (See page 8-136.)

Coolant
Check the coolant level in the coolant reservoir
when the engine is cold. (The coolant level will
vary with engine temperature.) The coolant level is
satisfactory if it is between the minimum and max-
imum level marks on the coolant reservoir. If the
coolant level is at or below the minimum level
mark, add additional coolant to bring the level up to
maximum level mark. If coolant is not available,
add distilled water. Change the coolant every two
years. (See pages 8-47–8-49 for details.)CAUTION:_ Hard water or salt water is harmful to the en-
gine. You may use soft water if you cannot get
distilled water. _
Coolant reservoir capacity
(up to the maximum level mark):
0.35 L (0.31 Imp qt, 0.37 US qt)

Coolant
The coolant level should be checked before each
ride.
Checking the coolant level
1. Place the vehicle on a level surface.
2. Open the hood. (See pages 8-17–8-19 for
hood opening and closing procedures.)
3. Check the coolant level in the coolant reser-
voir when the engine is cold as the coolant
level varies with engine temperature.NOTE:_ The coolant should be between the minimum and
maximum level marks. _4. If the coolant is at or below the minimum level
mark, remove the reservoir cap, add coolant
to the maximum level mark, install the reser-
voir cap, and then close the hood.
