CautionEES0006Z
lWhen installing rubber bushings, final tightening must be carried out under unladen conditions with tires
on flat, level ground. Oil will shorten the life of rubber bushings. Be sure to wipe off any spilled oil.
l“Unladen condition” means that fuel, coolant and lubricant are full and ready for drive. However, spare tire,
jack, and hand tools should be unloaded.
lAfter installing the removed suspension parts, always check wheel alignment and adjust if necessary.
lReplace the caulking nut with a new one. Install a new nut without wiping the oil off before tightening.
Precautions for Brake SystemEES000JA
lWhen installing rubber parts, final tightening must be carried out
under unladen condition* with tires on ground.
*: Fuel, radiator coolant and engine oil full. Spare tire, jack,
hand tools and mats in designated positions.
lUse flare nut wrench when removing or installing brake tubes.
lAfter installing removed suspension parts, check wheel align-
ment and adjust if necessary.
lAlways torque brake lines when installing.

CAN COMMUNICATIONPFP:23710
System DescriptionEKS001U3
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

Aiming AdjustmentEKS003CG
When performing headlamp aiming adjustment, use an aiming machine, aiming wall screen or headlamp
tester. Aimers should be in good repair, calibrated and operated in accordance with respective operation man-
uals.
If any aimer is not available, aiming adjustment can be done as follows:
For details, refer to the regulations in your own country.
lKeep all tires inflated to correct pressures.
lPlace vehicle and tester on one and same flat surface.
lSee that there is no-load in vehicle (coolant, engine oil filled up to correct level and full fuel tank) other
than the driver (or equivalent weight placed in driver's position).
