4.1 Warning and precaution

4.1.1 Warning and precaution

Assistant driving warning

Warning!

When the technician checks the fault part to be repaired, the assistant shall drive the vehicle; otherwise, it may
cause personal injury.

Warning for battery disconnection

Warning!

Unless directed, otherwise, the ignition and start switch must be in OFF or LOCK position, and all electrical loads
must be OFF before servicing any electrical component. Disconnect the negative battery cable if a tool or any
equipment easily comes in contact with an exposed electrical terminal. Failure to follow these precautions may
result in personal injury and/or damage to the vehicle or its components.

Warning for road test

Warning!

Test a vehicle on the roads under safe conditions and obey all traffic laws. Do not attempt any operation that could
jeopardize vehicle control. Failure to obey these precautions will lead to serious personal injury and vehicle
damage.

Precaution for engine lifting

Notes:

When raising or supporting the engine for any reason, do not use a jack under the oil pan, any sheet metal, or the
crankshaft pulley. Lifting the engine in an unapproved manner may cause damages to component.

Important precaution for excessive adhesive on flywheel bolts

Notes:

Appropriate sealant shall be applied on the fastener when assembling the component. If the sealant is excessive,
the part may be improperly assembled or the fastener is loose; if the part or fastener is improperly assembled, the
component will be loose or dropped off, thereby resulting in serous damage to the engine.
