General Description
VEHICLE DYNAMICS CONTROL (VDC)
5. RELAY BOX
C: CAUTION
Please clearly understand and adhere to the follow-
ing general precautions. They must be strictly fol-
lowed to avoid any injury to the person doing the
work or people in the area.
1. OPERATION
•Wear work clothing, including a cap, protective
goggles and protective shoes during operation.
•Remove contamination including dirt and corro-
sion before removal, installation or disassembly.
•Keep the disassembled parts in order and pro-
tect them from dust and dirt.
•Before disconnecting connectors of sensors or
units, be sure to disconnect the ground cable from
the battery.
•Before removal, installation or disassembly, be
sure to clarify the failure. Avoid unnecessary re-
moval, installation, disassembly and replacement.
•Be careful not to burn yourself, because each
part on the vehicle is hot after running.
•Be sure to tighten fasteners including bolts and
nuts to the specified torque.
•Place shop jacks or rigid racks at the specified
points.
2. OIL
When handling oil, follow the rules below to prevent
unexpected accidents.
•Prepare container and waste cloths when per-
forming work which oil could possibly spill. If oil
spills, wipe it off immediately to prevent from pene-
trating into floor or flowing outside, for environmen-
tal protection.
•Follow all government and local regulations con-
cerning waste disposal.
3. BRAKE FLUID
If brake fluid gets in your eyes or on your skin, do
the following:
•Wash eyes and seek immediate medical atten-
tion.
•Wash your skin with soap and then rinse thor-
oughly with water.
Follow all government and local regulations con-
cerning waste disposal.
