WARNING
Working on the batteries or the electrical system in your vehicle can cause serious acid burns, fires, explosions, or electrical shocks. Always read and heed the following WARNINGS and safety precautions before working on the batteries or the electrical system.
x Before working on the electrical system, always switch off the ignition and all electrical consumers and disconnect the negative (-) cable from the standard 12 Volt battery.
x When you change a light bulb, always switch off the light first.
x Always keep children away from battery acid and vehicle batteries in general.
x Always wear eye protection. Never let battery acid or lead particles come into contact with your eyes, skin, or clothing.
x Sulfuric battery acid is very corrosive. It can burn unprotected skin and cause blindness. Always wear protective gloves and eye protection. To reduce your risk of injury, never tilt the batteries, as this could spill acid through the vents and burn you.
x If you get battery acid in your eyes or on your skin, immediately rinse with cold water for several minutes and then get immediate medical attention. If you swallow any battery acid, get medical attention immediately.
x When disconnecting the batteries from the vehicle electrical system, always disconnect the negative cable (-) first and then the positive cable (+).
x Always switch off all electrical consumers before reconnecting 12 Volt batteries. Reconnect the plus cable (+) first and then the negative cable (-). Never reverse the polarity of the connections. This could cause a fire.
x A highly explosive mixture of gases is given off when the battery is being charged.
x Do not smoke and avoid fires, sparks, and open flames when working. Never create sparks or electrostatic charges when handling cables and electrical equipment. Never short circuit the battery terminals. High-energy sparks can cause serious personal injury.
x Never use or attempt to charge a damaged or frozen battery, or a battery that was frozen but has thawed. Charging a frozen or thawed battery could cause explosions and chemical burns! Replace damaged or frozen vehicle batteries immediately. A dead battery can freeze at temperatures around +32 °F (0 °C).
x If the battery has a vent line or tube, make sure that it is properly connected to the battery.
WARNING
California Proposition 65 Warning
x Battery posts, terminals, and related accessories contain lead and lead components, chemicals known to the State of California to cause cancer and reproductive harm. Wash your hands after handling.
NOTICE
x Do not expose the vehicle battery to direct sunlight for an extended period of time as ultraviolet rays may damage the battery housing.
x If the vehicle is left standing in the cold for a long time, protect the vehicle battery from freezing. A battery will be permanently damaged by freezing.
Emergency starting and starting the engine with a very weak vehicle battery or after the vehicle battery has been replaced may change or delete system settings (including time, date, personal convenience settings, and programming). Check the settings and correct as necessary once the vehicle battery has built up a sufficient charge.

Check all wiper blades regularly. Wiper blades that grab and squeak must be replaced if worn or
damaged and cleaned if dirty ⇒ .

Changing wiper blades
x Lift the wiper arm(s) away from the windshield.
x Press and hold the release button ⇒ fig. 159 (1).
x While lifting the wiper blade in the direction of the wiper arm, pull off the wiper blade in the direction of the arrow. This may require moderate force.
x Install a new wiper blade of same length and type onto the wiper arm by pushing in the opposite direction of the arrow until it latches.
x Carefully fold the wiper arm back down onto the windshield.
WARNING
Worn or dirty wiper blades reduce visibility and increase the risk of accidents and severe injuries.
x Always change wiper blades if they are damaged or worn, and if they cannot clean the windows sufficiently.
NOTICE
x Damaged or dirty wiper blades can scratch the windshield.
x Solvents, abrasive sponges and sharp-edged objects will damage the graphite coating on the wiper blades.
x Do not clean the windows with gasoline, nail polish remover, paint thinner or similar fluids.
x To help prevent damage to the engine hood and the windshield wiper arms, lift the wiper arms away from the windshield only when they are in the service position.
