If the engine will not start, first try starting it
usin
g the b
attery of another vehicle
››› page 52. You should only attempt to tow-
start a vehicle if charging the battery does
not work. This is done by leveraging wheel
movement.
When tow-starting a vehicle with a petrol en-
gine, do not tow it more than a short dis-
tance, otherwise unburned fuel can enter the
catalytic converter.
However, if your vehicle has to be tow-star-
ted:
● Engage 2 nd
or 3 rd
ge ar
.
● Keep the clutch pressed down.
● Switch the ignition on.
● Once both vehicles are moving, release the
clutch.
● As
soon as the engine starts, press the
clutch and mo
ve the gear lever into neutral.
This helps to prevent driving into the towing
vehicle.

the engine.
Jump leads
Jump leads must comply with standard DIN
