Service Information The service and repair information contained in this manual is intended for use by qualified, professional technicians. Attempting service or repairs without the proper training, tools, and equipment could cause injury to you or others. It could also damage the vehicle or create an unsafe condition. This manual describes the proper methods and procedures for doing service, maintenance, and repairs. Some procedures require the use of specially designed tools and dedicated equipment. Any person who intends to use a replacement part, a service procedure, or a tool that is not recommended by Honda, must determine the risks to their personal safety and the safe operation of the vehicle. If you need to replace any parts, always use the correct parts supplied by a Honda dealer. Never use inferior quality parts. FOR YOUR CUSTOMER'S SAFETY Proper service and maintenance are essential to the customer's safety and the reliability of the vehicle. Any error or oversight while servicing a vehicle can result in faulty operation, damage to the vehicle, or injury to others. Improper service or repairs can create an unsafe condition that can cause your customers or others to be seriously hurt or killed. Follow the procedures and precautions in this manual and other service materials carefully. FOR YOUR SAFETY Because this manual is intended for the professional service technician, we do not provide warnings about many basic shop safety practices (for example, hot parts-wear gloves). If you have not received shop safety training or do not feel confident about your knowledge of safe servicing practices, we recommend that you do not attempt to do the procedures described in this manual. Failure to properly follow instructions and precautions can cause you to be seriously hurt or killed. Follow the procedures and precautions in this manual carefully. Some of the most important general service safety precautions follow this text. However, we cannot warn you of every conceivable hazard that can arise in doing service and repair procedures. Only you can decide whether or not you should do a given task. IMPORTANT SAFETY PRECAUTIONS Make sure you have a clear understanding of all basic shop safety practices, and that you are wearing appropriate clothing and using safety equipment. When doing any service task, be especially careful of the following: - Read all of the instructions before you begin, and make sure you have the tools, the replacement or repair parts, and the skills required to do the tasks safely and completely. - Protect your eyes by using proper safety glasses, goggles, or face shields anytime you hammer, drill, grind, or work around pressurized air or liquids and springs, or other stored-energy components. If there is any doubt, put on eye protection. - Use other protective wear when necessary, such as gloves or safety shoes. Handling hot or sharp parts can cause severe burns or cuts. Before you grab something that looks like it can hurt you, stop and put on gloves. - Protect yourself and others whenever you have the vehicle up in the air. Anytime you raise the vehicle, either with a lift or a jack, make sure that it is always securely supported. Use safety stands if needed. - Protect yourself by wearing an approved welding helmet, gloves, and safety shoes anytime you are welding. You can receive burns from hot parts; allow the parts to cool before working in that area. - Protect yourself from paints and harmful chemicals by wearing an approved respirator, eye protection, and gloves whenever you are painting. Spray paint only in an approved paint booth that is well ventilated. Make sure the engine is off before you begin any servicing procedures, unless the instruction tells you to do otherwise. This will help eliminate several potential hazards: - Carbon monoxide poisoning from engine exhaust. Be sure there is adequate ventilation whenever you run the engine. - Burns from hot parts or coolant. Let the engine and exhaust system cool before working in those areas. - Injury from moving parts. If the instruction tells you to run the engine, be sure your hands, fingers, and clothing are out of the way. Gasoline vapors and hydrogen gases from batteries are explosive. To reduce the possibility of a fire or explosion, be careful when working around gasoline or batteries: - Use only a nonflammable solvent, not gasoline, to clean parts. - Never drain or store gasoline in an open container. - Keep all cigarettes, sparks, and flames away from the battery and all fuel-related parts.

If the vehicle needs to be towed, call a professional towing service. Improper towing preparation will damage the transmission. Follow the below procedure exactly. If you cannot shift the transmission or start the engine, the vehicle must be transported on a flat-bed tow truck. Trying to lift or tow the vehicle by the bumpers will cause serious damage. The bumpers are not designed to support the vehicle's weight. It is best to tow the vehicle no farther than 50 miles (80 km), and keep the vehicle speeds below 35 mph (55 km/h) except when loading on a flat-bed tow truck. For vehicles equipped with the engine start/stop button If the 12 volt battery is discharged, the ACCESSORY mode cannot be selected by pushing the engine start/stop button. Charge or replace the 12 volt battery to unlock the steering wheel before towing. If the ACCESSORY mode cannot be selected because of in an electrical problem other than a discharged 12 volt battery, the flat-bed tow truck is the only way to transport the vehicle. For vehicles equipped with the electric parking brake If the 12 volt battery is discharged, the electric parking brake cannot be canceled by pushing the electric parking brake/automatic brake hold switch. Charge or replace the 12 volt battery to release the parking brake before towing. If the electrical parking brake is disabled in an electrical problem or severe vehicle damage, the vehicle must be transported on a flat-bed tow truck. For vehicles equipped with the neutral position holding mode Neutral Position Holding Mode is automatically canceled after several minutes. For vehicles equipped with the park lock If the transmission cannot shift from the P position/mode to the N position/mode because of an electrical problem or severe vehicle damage, shift to the N position/mode manually, and transport the vehicle by a flat-bed tow truck. See more information on "How to Release Park Lock." Emergency Towing There are three popular methods of towing a vehicle. Towing Method Transmission Type Shift Position Notes M/T CVT and A/T M/T CVT and A/T Cable-type Equipment ○ ○ Neutral N Check the transmission fluid amount and for leaks. If transmission fluid leaks are found or fluid amount is low, the vehicle must be transported by a flat-bed tow truck. Turn the vehicle to the ACCESSORY or ON mode, and then release the parking brake. Flat-bed Tow Truck Equipment ○ ○ Neutral P Secure the vehicle securely on a flat-bed tow truck. Apply the parking brake. Front Wheel Lift Equipment ○ ○ Neutral N Turn the vehicle to the ACCESSORY or ON mode, and then release the parking brake.
Towing Hook/Tie Down Hook Slots Locations The front towing hook can be used with a winch to pull the vehicle onto the flat-bed tow truck, and the front/rear tie down hook slots can be used to secure the vehicle to the flat-bed tow truck. The tie down hook slots are covered with rubber plugs. Be sure to reinstall them after use. To avoid damage to the vehicle, use the towing hook for straight flat ground towing only. Do not tow on an angle. This vehicle is not equipped with a rear towing hook. Do not use the rear bumper or the rear tie down hook slots as a towing hook. It will cause a severe damage of rear of the vehicle.
