Vehicle battery

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.

Checklist
For your own safety and that of your passengers, carry out the following steps in the order listed ⇒ :
1. Park the vehicle at a safe distance from traffic and on a suitable surface ⇒ .
2. Switch on emergency flashers by pressing the  switch ⇒ fig. 165.
3. Apply the parking brake to help prevent the vehicle from moving
4. Shift the transmission into Park (P) (automatic) or Neutral (manual only)
5. Stop the engine and remove the key from the ignition switch
6. Have all passengers exit and go to a safe location away from moving traffic, such as behind a
guard rail.
7. Take all vehicle keys with you when leaving your vehicle.
8. Set up a warning triangle or other warning device in order to alert other motorists and cyclists.
9. Let the engine cool down and get expert assistance if necessary.
If the emergency flashers are on, use the turn signal lever to indicate a direction or lane change, for
example when the vehicle is being towed. This temporarily interrupts the emergency flashers.
Switch on the emergency flashers when:
x Traffic suddenly slows down or stops in front of you to warn those approaching from behind.
x In any emergency situation.
x If the vehicle breaks down.
x When being towed.
Always obey traffic laws that govern the use of emergency flashers where you are driving.
If the emergency flashers are not working, a different method – as permitted by law – must be used to
alert other motorists and cyclists to the breakdown.
WARNING
Disregarding the safety-related checklist may lead to accidents and serious personal injuries.
x Always review and follow the checklist. Follow accepted safety practices and use common
sense.
WARNING
The vehicle exhaust system and the catalytic converter get very hot. They can cause fires and
serious personal injury.
x Never park where parts of the hot exhaust system or catalytic converter could ignite
flammable materials, such as dry grass, brush, leaves, spilled fuel, etc.
The vehicle battery will be drained if the emergency flashers are on for a long time – even if the
ignition is switched off.

WARNING
Before using the emergency procedure to close the CSC roof, park the vehicle as far away
from moving traffic as possible. If necessary, switch on the emergency flashers and set up a
warning triangle. Obey all applicable legal requirements.
NOTICE
If the vehicle's battery fails or the power windows won't work, the door windows are not
lowered when the door is opened or closed. Always close and open the door carefully to help
prevent damage to the window, the paint, or the rubber seal.
NOTICE
x Before using the emergency procedure to close the CSC roof and while doing it, check the
area behind the vehicle for possible obstacles and make sure there is enough room to avoid
damage. Rear lid assist does not work before and during the emergency closing procedure.
x Never close the CSC roof if the car is on a workshop hoist, parked with one side on a curb,
or raised on a car jack or jackstands.
NOTICE
To help prevent vehicle damage, carefully remove and properly reinstall parts after emergency
locking or unlocking.
