During thech arging process and starting
assis tance, the battery may release an explo‐
sive gas mixture. #
Avoid fire , open flames, creating spar ks
and smoking. #
Make sure that there is suf ficient venti‐

Do not lean over a batter y. &
WARNING Risk ofexplosion from a fro‐
zen battery
A dischar ged battery may freeze at temp era‐
tures slightly abo veor below freezing point.
During starting assis tance or battery charg‐
ing, bat tery gas may be released. #
Alw aysth aw a frozen bat tery out first
before charging it or per form ing start‐
ing assis tance. If
th e indicator/warning lamps in the instrument
clus ter do not light up at low temp eratures, it is
ve ry likely that the dischar ged battery has fro‐
zen. In this case you may neither jump-s tart the
ve hicle nor charge the batter y.
The service life of a battery that has been

WARNING Risk of accident caused by
re peated drop in tire pressure
If th e tire pressure drops repeatedl y,the
wheel, valve or tire may be damaged.
Insuf ficient tire pressure can cause the tires
to bur st. #
Inspect the tire for signs of fore ign
objects. #
Check whe ther the wheel or valve has a
leak. #
Ifyo u are unable torectify the damage,
conta ct aqualified specialist workshop. Yo
u can find information on tire pressure forthe
ve hicle's factor y-ins talled tires on thefo llowing
labels:
R Tire and Loading In form ation placard on the
B‑pillar of your vehicle (→ page 384).
R Tire pressure table on the inside of the fuel
fi ller flap (→ page379).
Obse rveth e maximum tire pressure
(→ page 390). Use a suitable tire pressure
gauge tocheck the
tire pressu re. The ou ter appearance of a tire
does not permit any reliable conclusion about
th e tire pressure.
Ve hicles with a tire pressure monitoring sys‐
te m: You can also check the tire pressure using
th e on-board computer.
Only cor rect tire pressure when the tires are
cold. Conditions for cold tires:
R The vehicle has been par ked with the tires
out of direct sunlight for at least thre e hours.
R The vehicle has tr aveled less than 1 mile
(1.6 km).
A rise in the tire temp erature of 18°F (10 °C)
increases the tire pressure byappr ox.10 kPa
(0.1 bar/1.5 psi). Take this into account when
ch ecking the tire pressure of warm tires.
The tire pressu re recommended for increased
load/speed in the tire pressure table can af fect
th eride comfort. &
WARNING Risk of accident from unsuita‐
ble accesso ries on the tire valves
If yo u mount unsuitable accessories on totire
va lves, the tire valves may be overloaded and
malfunction, which can cause tire pressure
loss. Tire pressure monitoring sy stems for
re trofitting will cause the tire valve toremain
open. This can also result in tire pressure
loss. #

caps specifically appr ovedby

DANG ER Risk of accident due toincor‐
re ct tire pressure
Every tire, including the spare (if pr ovided),
should be checked when cold at least once a
month and inflated tothe pressure recom‐
mended bytheve hicle manufacturer (see
Ti re and Loading In form ation placard on the
B-pillar on the driver ’sside or the tire pres‐
sure label on the inside of the fuel filler flap
of your vehicle). If your vehicle has tires of a
dif fere nt size than the size indicated on the
Ti re and Loading In form ation placard or the tire pressu
retable, you need todeterm ine
th e proper tire pressure forth ose tires.
As an added saf etyfe ature, your vehicle has
been equipped with a tire pressure monitor‐
ing sy stem (TPMS) that illuminates a low tire
pressure indicator lamp when one or more of
yo ur tires are significantly underinflated.
Ac cording ly, if the low tire pressure indicator
lamp lights up, you should stop and check
yo ur tires as soon as possible, and inflate
th em tothe proper pressure. Driving on a
significant lyunderinflated tire causes the tire
to ov erheat and can lead totire failure.
Un derinflation also increases fuel consump‐
tion and reduces tire tread life, and may
af fect theve hicle's handling and braking abil‐
ity. Please no tethat the TPMS is not a substi‐
tute for proper tire maintenance, and it is the
driver's responsibility tomaintain cor rect tire
pressure, even if underinflation has not
re ached the le velto trig ger illumination of
th e TPMS low tire pressure indicator lamp.
Yo ur vehicle has also been equipped with a
TPMS malfunction indicator toindicate when th
e sy stem is not operating proper ly. The
TPMS malfunction indica tor is combined with
th e low tire pressure indicator lamp. When
th e sy stem de tects a malfunction, the indica‐
to r lamp will flash for appro ximately a minute
and then remain continuously illumina ted.
This sequence will continue upon subsequent
ve hicle start-ups as long as the malfunction
ex ists.
When the malfunction indicator is illumina‐
te d, the sy stem may not be able todetect or
signal low tire pressure as intended. TPMS
malfunctions may occur for a variet y of rea‐
sons, including the ins tallation of incompati‐
ble replacement or alternate tires or wheels
on theve hicle that pr eventthe TPMS from
functioning properly.
Alw aysch eck the TPMS malfunction warning
lamp af terre placing one or more tires or
wheels on your vehicle toensure that the
re placement or alternate tires and wheels
allow the TPMS tocontinue tofunction prop‐
erly. Wheels and tires
