– The blown fuse must be changed with a new fuse with the same rating (same colour and same markings) and same size → . ● The voltage of the 12-volt battery must be the same as the voltage of the unpowered 12-volt battery and the capacity of both bat- teries must be approximately the same (see specifications on the battery). – Insert the cover again or close the fuse box cover. NOTICE ● Never perform jump starting on a vehicle with a frozen or thawed 12-volt vehicle bat- tery. A discharged 12-volt vehicle battery can already freeze at temperatures around 0°C. Damage can also be caused at other locations in the electrical system if a fuse is replaced with a fuse that has a higher rating.
● Always replace a 12-volt vehicle battery which is frozen or has been frozen. ● A highly explosive mixture of gases is given off when the battery is charging! Always keep fire, sparks, naked flames and lit ciga- rettes away from the 12-volt vehicle battery. Do not use mobile phones when connecting or disconnecting jump starting. Jump starting Introduction This chapter contains information on the follow- ing subjects: ● Position the leads in such a way that they cannot come into contact with any moving parts in the engine compartment For technical reasons, your vehicle may not be push-started → .
– Jump starting procedure 160 ● Never confuse the positive battery terminal with the negative battery terminal. ● Observe the jump lead manufacturer’s in- structions. If the engine cannot be started because the 12- volt vehicle battery is flat, the discharged battery can be connected to the 12-volt battery of an- other vehicle to start the engine. In order to avoid serious damage to the vehicle electrical system, please observe the following items during operation: NOTICE A suitable cable is required for jump starting. Cross section of cable for jump starting: – at least 25 mm 2 for vehicles equipped with gasoline engines. ● An incorrect cable connection may cause a system short circuit.
WARNING ● Use only jumper start cables with safety insu- lated electrode clips. Using the jump leads incorrectly or performing the jump start procedure incorrectly can cause the vehicle battery to explode. This can result in serious injuries! To prevent battery explosion, observe the following rules: ● The two vehicles must not contact each other, otherwise, once connected to the positive ter- minal, the current will flow immediately. NOTICE ● Always be fully aware of the hazards when working with 12-volt vehicle batteries and electrical systems. Improper operation can easily cause fire, chemical burns, and electric shock.
Always read and observe the warnings and safety information before carrying out any kind of work on the 12-volt vehicle bat- tery. → page 179 Tow-starting the vehicle can cause considerable damage to the vehicle. 182.5C1.TRO.74 If and when 159
