108Driving
Driving and parking

Particularly avoid fire, open flames, creatingsparks and smoking. Ensure there is sufficient ven-
tilation while charging and jump-starting. Do not lean over abattery.
GWARNING
During the charging process, abattery produces hydrogen gas. If ashort circuit occurs or sparks
are created, the hydrogen gas can ignite. There is arisk of an explosion.
RMake sure that the positive terminal of aconnected battery does not come into contact with
vehicle parts.
RNever place metal object sortools on abattery.
RIt is importan tthat you observe the described order of the battery terminals when connecting
and disconnectin gabattery.
RWhen jump-starting, make sure that the battery poles with identical polarity are connected.
RIt is particularly importan ttoobserve the described order when connectin gand disconnecting
the jumper cables.
RNever connect or disconnect the battery terminals while the engine is running.
GWARNING
Ad ischarged battery can freeze at temperatures below freezin gpoint. When jump-starting the
vehicle or charging the battery, gases can escape from the battery. There is arisk of an explosion.
Allow the frozen battery to thaw out before charging it or jump-starting.
!Avoid repeated and lengthy starting attempts. Otherwise, the catalytic converter could be
damaged by the non-combusted fuel.
If the warning and indicator lamps do not light up on the instrument cluster when temperatures are
low, it is probably because the discharged battery has frozen. In this case, you may neither charge
the battery nor jump-start the vehicle. The service life of athawed-out battery may be shorter .The
starting characteristics can be impaired, particularly at low temperatures. Have the thawed-out
battery checked at aqualified specialist workshop.
Do not start the vehicle using arapid charging device. If your vehicle's battery is discharged, the
engine can be jump-started from another vehicle or from asecond battery using jumper cables.
Observe the following points:
RThe battery is not accessible in all vehicles. If the other vehicle's battery is not accessible, jump-
start the vehicle using asecond battery or ajump-starting device.
RYou may only jump-start the vehicle when the engine and exhaust system are cold.
RDo not start the engine if the battery is frozen. Let the battery thaw first.
RJump-starting may be performed only using batteries with anominal voltage of 12 V.
ROnly use jumper cables which have asufficient cross-section and insulated terminal clamps.
RIf the battery is fully discharged, leave the battery that is being used to jump-start connected for
afew minutes before attempting to start .This charges the battery slightly.
RMake sure that the two vehicles do not touch.
Make sure that:
Rthe jumper cables are not damaged.
Rwhen the jumper cables are connected to the battery, uninsulated sections of the terminal clamp
do not come into contact with other metal sections.
Rthe jumper cables cannot come into contact with parts which can move when the engine is
running, such as the V-belt pulley or the fan.
