TiresCheck tire pressure regularly to make sure it
is at the recommended specifications. Also
check for wear and damage. Tire pressure
Use the tire pressure gauge to check and ad-
just tire pressures when the tires are cold. Tire
pressures must be equal on both sides.
WARNING! Operation of this vehicle with
improper tire pressure may cause severe
injury or death from loss of control or roll-
over. Tire pressure below the minimum
specified could also cause the tire to dis-
lodge from the rim under severe riding
conditions.

EBU32391CoolantThe coolant level should be checked before
each ride. In addition, the coolant must be
changed at the intervals specified in the peri-
odic maintenance and lubrication chart.
Checking the coolant level1. Park the vehicle on a level surface.
2. Check the coolant level in the coolant reservoir when the engine is cold as the
coolant level varies with engine tempera-
ture.TIPThe coolant should be between the minimum
and maximum level marks.

9. Disconnect the coolant reservoir hose,and then drain the coolant from the cool-
ant reservoir.
10. After draining the coolant, thoroughly flush the cooling system with clean tap
water.
11. Install the coolant drain bolt and its new gasket and then tighten the bolt to the
specified torque. 12. Connect the coolant reservoir hose.
13. Pour the recommended coolant into the
radiator until it is full.
14. Pour the recommended coolant into the
reservoir to the maximum level mark, and
then install the reservoir cap.
NOTICEECB02190Mix antifreeze with distilled water only.
However, if distilled water is not available,
soft water may be used for refilling. Do not
use hard water or salt water since they are
harmful to the engine.
