r(For the details of lubrication points and type of lubricants to be applied, refer to the illustrated index and various work Dro-cedure (such as Assembly/Reassembly, Replacement, Overhaul, Installation. etc.) contained in each section,
*1: Always use Genuine Honda Manual Transmission Fluid (MTF). Using motor oil can cause stiffer shifting because itdoes not contain the proper addtuves.*2: Always use Genuine Honda Premium Formula Automatic Transmission Fluid (ATF). Using a non-Honda ATF can affectshift quality.*3: Always use Genuine Honda DOT 3 B.ake Fluid, Using a non-Honda brake fluid can cause corrosion and decrease thelife of the system.'4: Always use Genuine Honda Power Steering Fluid-V or S. Using any other type of power steering fluid or automatictransmission fluid can cause increase v,/ear and poor steering in cold weather.
