WARNING
Ad ischarged batterycanfreeze attemperatures belowfreezing point.Whenjump-st artingthe
vehicle orcharging thebattery, gasescanescape fromthebattery. Thereisar isk ofan explo-
sion.
Allow thefrozen battery tothaw outbefore charging itor jump-st arting.
! Avoid
repeated andlengthy startingattempt s.Otherwise, thecatalytic convertercould be
damaged bythe non- combusted fuel.
If the indicator/warnin glamps donot light upatlow temperatures, itis very likely thatthedis-
charged batteryhasfrozen .Int his case, youmay neither chargethebattery norjump-st artthe
vehicle. Theservice lifeofat hawed-out batterymaybeshorter. Thestartin gcharacterist icscan
be impaired, particularly atlow temperatures. Havethethawed-out batterycheckedataq uali-
fied specialist workshop.
Do not start thevehicle usingarapid charging device.Ifyour vehicle's batteryisdischarged, the
engine canbejump-st artedfromanother vehicleorfrom adonor battery usingjumper cables.
Observe thefollowing points:
R The battery isnot accessible inall vehicles. Ifthe other vehicle's batteryisnot accessible,
jump-st artthe vehicle usingadonor battery orajump-st artingdevice.
R You may onlyjump-st artthe vehicle whentheengine andexhaust systemarecold.
R Do not start theengine ifthe battery isfrozen .Let the battery thawfirst.
R Only jump-st artfrom batteries witha12V voltage rating.
R Only usejumper cableswhichhaveasufficient cross-sectionandinsulated terminalclamps.
R Ifthe battery isfully discharged, leavethebattery thatisbeing usedtojump-st artconn ected
for afew minutes beforeattempt ingtostart. Thischarges thebattery slightly.
R Make surethatthetwo vehicles donot touch.
Make surethat:
R The jumper cablesarenot damaged.
R Bare parts ofthe terminal clampdonot come intocontactwith other metal partswhile the
jumper cablesareconn ected tothe battery.
R The jumper cablescannot comeintocontactwith parts which canmove whentheengine is
running, suchasthe V-belt pulleyorthe fan.

Do not overload thetires byexceeding the
specified loadlimit. Themaximum permissible
load canbefound onthe vehicle's Tireand
Loading Information placardonthe B-pillar on
the driver's side(Ypage 280).
Example:
Load-bearing index91indicates amaximum
load of1,356 lb(61 5kg)that thetires can
bear. Forfurther information onthe maximum
tire load inkilograms andlbs,see

For further information onthe load bearing
index, see"Load index" (Ypage 286).
