Removing/stowing the reflective
safety jackets
The reflective safety jackets are located in the
safety jacket compartments in the stowage
compartments.
XTo remove: pullout safety jacket bag :with
the reflective safety jacket by loop ;.
XOpen safety jacket bag:and pul lout the
reflective safety jacket.
XTo stow: fold the reflective safety jacket, roll
it up and stow it in safety jacket bag :.
XSlidesafety jacket bag :along the lower
edge of the armres tinto the safety jacket
compartment. Meanwhile, ensure that
loop ;hangs out wel lwithi nreach.
iRemove anew reflective safety jacket from
its packaging material before sliding it into
the safety jacket compartment. The packag-
ing material may otherwise caus eittoslipo ut
or make removing it difficult.
Observe the lega lrequirements in each country.

-the correct size is used, and
-the reflective safety jackets are fastened
correctly.
REnsure before use that the reflective safety
jackets are cleana nd intact. The special prop-

RThe reflective safety jackets should be stored
in their original packaging in adry place away
from sources of heata nd light.

-after 15 washes, and/or
-if the reflective strips have become
scratched,and/or
-if the backing material and/or reflective
strips have become soiled and cannot be

General notes
With MOExtended tire s(tires with run fla tchar-

or more tires. The affected tire mus tnot show
any clearl yvisible damage.
You can recognize MOExtended tire sbythe
MOExtended marking which appears on the
sidewal lofthe tire .You will find this marking
next to the tire size designation, the load-bear-
ing capacity and the speed index (
Ypage 330).
MOExtended tire smay only be used in conjunc-
tion with an active tire pressure loss warning
system or with an active tire pressure monitor.
If ap ressure loss warnin gmessage appears
in the multifunctio ndisplay:
Robserve the instructions in the display mes-
sages (Ypage 241).
Rcheck the tire for damage.
Rif driving on, observe the following notes.

laden it is approximately 19 miles (30 km). In addition to the vehicl
eload, the driving dis-
tance possible depends upon:

GWARNING
If the required tire pressure is not reached
after the specified time, the tire is too badly
damaged. The tire sealant cannot repair the
tire in this instance. Damaged tires and atire
pressure that is too low can significantly
impair the vehicle's braking and driving char-
acteristics. There is arisk of accident.
Do not continue driving. Contact aqualified

Battery (vehicle)
12 Vb attery –important safety notes
Special tools and expert knowledge are required
when working on the battery, e.g. removal and
installation .You should therefore have all work
involvin gthe battery carried out at aqualified
specialist workshop.
GWARNING
Work carried out incorrectly on the battery
can lead, for example, to ashort circuit and
thus damage the vehicle electronics. This can
lead to function restriction sapplying to
safety-relevant systems, e.g the lighting sys-
tem, the ABS (anti-loc kbraking system) or the
ESP
®(Electronic Stability Program). The oper-
ating safety of your vehicle may be restricted.
You could lose control of the vehicle, for
example:
Rwhen braking
Rin the event of abrupt steerin gmaneuvers
and/or when the vehicle's speed is not
adapted to the road conditions
There is arisk of an accident.
In the event of ashort circuit or asimilar inci-
dent, contact aqualified specialist workshop
immediately. Do not drive any further .You
should have all work involvin gthe battery car-
ried out at aqualified specialist workshop.
For further information about ABS and ESP
®,
see (Ypage 62) and (Ypage 67).
All vehicles except vehicles with alithium-
ion battery:
GWARNING
Electrostatic build-up can lead to the creation of sparks, which could ignite the highly explo-
sive gases of abattery. There is arisk of an
explosion.
Before handling the battery, touch the vehicle
body to remove any existin gelectrostatic
build-up.
The highly flammable gas mixture forms when
charging the battery as well as when jump-start-
ing.
Always make sure that neither you nor the bat-
tery is electrostatically charged. Abuild-up of
electrostatic charge can be caused, for exam-
ple:
Rby wearing clothin gmade from synthetic
fibers
Rdue to friction between clothin gand seats
Rif you push or pull the battery across the car-
pet or other synthetic materials
Rif you wipe the battery with acloth
GWARNING
During the charging process, abattery produ-
ces 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 a
connected battery does not come into con-
tact with vehicle parts.
RNever place metal object sortools on abat-
tery.
RIt is importan tthat you observe the descri-
bed order of the battery terminals when
connectin gand 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 dis-
connectin gthe jumper cables.
RNever connect or disconnect the battery
terminals while the engine is running.

GWARNING
Battery acid is caustic. There is arisk of injury.
Avoid contact with skin, eyes or clothing. Do not inhale any battery gases. Do not lean over the
battery. Keep children away from batteries. Wash away battery acid immediately with plenty of
clean water and seek medical attention.
GWARNING
During charging and jump-starting, explosive gases can escape from the battery. There is arisk
of an explosion.
Particularly avoid fire, open flames, creating sparks 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 objects or tools on abattery.
RIt is important that you observe the described order of the battery terminals when connecting
and disconnecting abattery.
RWhen jump-starting, make sure that the battery poles with identical polarity are connected.
RIt is particularly important to observe the described order when connecting and disconnecting
the jumper cables.
RNever connect or disconnectt he battery terminals while the engine is running.
GWARNING
Ad ischarged battery can freeze at temperatures below freezing point. 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.
If, at low temperatures, the indicator lamps/warning lamps in the instrument cluster do not light up,
it is highly likely that the discharged battery has frozen.Int his case, you may neither charge the
battery nor jump-start the vehicle. The service life of athawed-out battery may be shorter. The
starting characteristicsc an be impaired, particularly at low temperatures. Have the thawed-out
battery checked at aqualified specialist workshop.
