• Gives you additional information that will help you complete a particular procedure.
The following list contains some general WARNINGS that you should follow while working on a vehicle.
• Always wear safety glasses for eye protection.
• Use safety stands whenever a procedure requires you to be under the vehicle.
• Make sure that the ignition switch is always in the OFF position, unless otherwise required by the procedure.
• Set the parking brake when working on the vehicle. If you have an automatic transaxle, set the vehicle in the P position.
• Place supporters against the front and rear surfaces of the tires to prepare for the vehicle suddenly moving.
• Operate the engine only in a well-ventilated area to avoid the danger of carbon monoxide poisoning.
• Keep yourself and your clothing away from moving parts when the engine is running, especially the drive belts.
• To prevent serious burns, avoid contact with hot metal parts such as the radiator, exhaust manifold, tail pipe, catalytic converter and muffler.
• Do not smoke while working on a vehicle.
• To avoid injury, always remove rings, watches, loose hanging jewelry, and loose clothing before beginning to work on a vehicle.
• When it is necessary to work under the hood, keep hands and other objects clear of the radiator fan blades! Your vehicle may be equipped with a cooling fan that may turn on, even though the ignition switch is in the OFF position. For this reason care should be taken to ensure that the radiator fan electric motor is completely disconnected when working under the hood and that the engine is not running.

Battery Caution Label Description

Warning / Caution Label (Cont'd)
| A. Keep lighted cigarettes and all other flames or sparks away from the battery. |
| B. Wear safety glasses for eye protection when charging or working near a battery. Always provide ventilation when working in an enclosed space.
|
| C. Keep batteries out of the reach of children because batteries contain highly corrosive SULFURIC ACID. Do not allow battery acid to contact your skin, eyes, clothing or paint finish. |
| D. If any electrolyte gets into your eyes, rinse off your eyes with clean water for at least 15 minutes and get immediate medical attention. If possible, continue to apply water with a sponge or cloth until medical attention is received. If electrolyte gets on your skin, thoroughly wash the contacted area. If you feel a pain or a burning sensation, get medical attention immediately. |
| E. Always read the following instructions carefully before handling a battery. |
| F. Hydrogen, which is a highly combustible gas,is always contained in battery cells and may explode if ignited. |

|
• After reconnecting or recharging a discharged battery, the ESP OFF indicator may illuminate.
• In this case, turn the handle half way to the left and right whilst the ignition switch is in the ON position.
• Then, restart the engine after the ignition is OFF.
• The ESP OFF indicator may turn OFF.
• If the ESP OFF indicator does not turn OFF, have the system checked by referring to DTC. (Refer to the BR group.)
- Lift and Support Points
• When heavy rear components such as suspension, fuel tank, spare tire, tailgate and trunk lid are to be removed, place additional weight in the luggage area before hoisting. When substantial weight is removed from the rear of the vehicle, the center of gravity may change and can cause the vehicle to tip forward on the hoist.
• With each tire/wheel assembly weighing approximately 30lbs (14kg), placing the front wheels in the luggage area can help the weight distribution.
• Use the same support points to support the vehicle on safety stands.
1.Place the lift blocks under the support points as shown in the illustration.
2.Raise the hoist a few inches (centimeters) and rock the vehicle to make sure that the vehicle is firmly supported.
3.Raise the hoist to full height to check whether the vehicle is firmly supported.
