OVERVIEW OF BODY FEATURES
2018 models have these body features: • Next-Generation Advanced Compatibility Engineering ™ (ACE ™) body structure.
• Extensive use of high tensile strength steel (64.4%), including 36.5% in grades 780, 980, and 1,500 MPa.
• Roof attached with laser brazing method along both apertures.
• Extensive use of impact-resistant adhesive throughout the construction process. • Blue Eyes brilliant LED headlights. • Active grille shutter system.
• Aluminum hood panel and bumper beams for weight reduction and improved fuel efficiency. • Auto emergency brake engagement, Rear cross traffic monitor, Traffic sign recognition, Driver attention monitors, Capless fuel filler and Automatic Hi Beam headlights.

NEW MODEL BODY TECHNOLOGY
BODY CONSTRUCTION AND HIGH STRENGTH STEEL CONTENT FOR 2012-14 MODELS •Steel parts are color-coded based on their tensile strength in Megapascals (MPa).
•High strength steel is defined as any steel with a tensile strength of 340 MPa or higher.
•Steel repair and welding procedures vary depending on the tensile strength of the parts involved. NOTE: These illustrations are for general reference only. Some body parts, such as the front pillars, are constructed from multiple layers of different tensile strength steels. Always refer to the body repair manual body construction section for specific steel tensile strength information.
ROOF PANEL ATTACHMENT
The roof on the 2018 Accord is attached with weld bonding in the corners as well as laser brazing along both side apertures. Replacement will require adhesive bonding, weld bonding and the purchase of rubber dams and a bracket kit that need to be welded into the apertures so the new roof panel can be bolted to them.
ALUMINUM PARTS & REPAIRABILITY
The hood on the 2018 Accord is constructed from Aluminum alloy.
Repairability Issues: •
Minor damage to the aluminum hood may be repaired by body shops that have dedicated aluminum repair facilities and tools.
•
To prevent galvanic corrosion, some fasteners for aluminum parts are considered one-time use and must be replaced if removed as specified in the electronic service manual or body repair manual.
TOWING AND LIFTING PRECAUTIONS
• Flatbed towing equipment is the preferred method to transport this vehicle.
•
Front wheel lift towing equipment may also be used to tow this vehicle.
For more information, refer to “Emergency Towing” in the owner’s guide. • Lift or jack only at the points specified in the owner’s guide to avoid damaging the vehicle.
• Do not lift or tow this vehicle by its bumpers, or serious damage will result.
•
For more information, refer to “Lift and Support Points” in the service or body repair manual.
BODY REPAIR INFORMATION
NOTE : The following content is intended only to highlight new/special concerns. No body repairs should be attempted without first referencing the appropriate body repair manual for complete information.
SECTIONING (CUT AND JOINT) GUIDELINES
Various high-strength steel materials with different sheet thicknesses and strengths are applied in many places that vary by body design in order to increase collision safety performance, body stiffness,
and weight reduction.  Stiffening members inside each part (patch, stiffener, etc.) are also specified in detail.
USE OF HEAT DURING BODY STRAIGHTENING AND REPAIR When you are doing body straightening and repair procedures, follow these guidelines:
• DO NOT apply heat to any body part during straightening. This may compromise the internal structure and strength of high-strength steel parts. • Any part that has heat applied to it during straightening MUST be replaced with new parts. • Ignoring these instructions may significantly reduce occupant protection in any subsequent collision.
Follow these guidelines to avoid an unsafe repair: •
Sectioning (cut and joint) should usually be avoided except for mild steel outer panels and floor panels unless a specific procedure is provided in the body repair manual. •
However, depending on the type of vehicle damage, steel parts with a tensile strength ≤ 780 MPa may be sectioned provided ALL of the following conditions are met:
– Sectioning must be done in a single-layer area of
the part. – Multi-layer internal steel reinforcements and
stiffeners must not be cut. – The repair is not in a load bearing area such as
engine, transmission, or suspension mounting points.
•
Replace body structural components such as stiffeners, reinforcements, and other multi-layered steel parts as
assemblies that match the replacement parts configuration. • Approved welding methods are listed in the table. •
Refer to the body repair manual section “Parts Sectioning (Cut and Joint) Guidelines ” for complete information.
