Incorrect jump-starting can lead to a battery explosion. The battery explosion may result in severe injury or death. It may also result in damage to the vehicle. Be sure to follow the instructions in this section.
Explosive hydrogen gas is always present in the vicinity of the battery. Keep all sparks and flames away from the battery.
Always wear suitable eye protection and remove rings, bracelets, and any other jewellery whenever working on or near a battery.
Never lean over the battery while jump-starting.
Never allow battery fluid to come into contact with eyes, skin, clothes, or the vehicle’s painted surfaces. Battery fluid is a corrosive sulphuric acid which can cause severe burns. If the fluid comes into contact with anything, immediately flush the contacted area with plenty of water.
Keep the battery out of the reach of children.
The booster battery must be rated at 12 volts. Use of an incorrectly rated battery will damage your vehicle.
Never attempt to jump-start a frozen battery. It could explode and cause serious injury.
Jump-Starting Procedure
Check if the parking brake is applied. If not, after connecting the vehicle with the booster battery (after step 8), apply the parking brake. The vehicle has an electric parking brake; for more information, see “Electric Parking Brake” (P.157).
Prepare the vehicle with the booster battery for the vehicle being jump-started.
CAUTION
Do not allow the two vehicles to touch.
Shift the transmission (MT models) into the N (Neutral) position. For Xtronic transmission, follow the specific instructions in the vehicle manual.
