Fu nctions of ABS (anti-lock braking sy st em)
ABS re gulates th e brake pressure in critical driv‐
ing situations: R
During braking, e.g. at maximum full-s to p
braking or insuf fi cient traction of th e tires,
th e wheels are pr ev ented from blocking.R
Ve hicle st eerability while braking is ensured.
If ABS inter ve nes when braking, yo u will fe el a
pulsing in th e brake pedal. The pulsating brake
pedal can be an indication of hazardous ro ad
conditions and can ser ve as a re minder to ta ke
ex tra care while driving.
Sy st em limitations R
ABS is active from speeds of appr ox . 5 mp h
(8 km/h). R
ABS may be impaired or may not function if a
malfunction has occur re d and th e ye l‐
low % ABS wa rn ing lamp lights up contin‐
uously in th e instrument clus te r af te r th e
engine is st ar te d. Fu nction of BA S (Brake Assist Sy st em)

WA RNING Risk of an accident caused by
a malfunction in BA S (Brake Assi st Sys‐
te m)
If BA S is malfunctioning, th e braking dis ta nce
in an emergency braking situation is
increased.

WA RNING Risk of entrapment from ve hi‐
cle lo we ri ng
When lo we ri ng th e ve hicle, people could
become trapped if th eir limbs are between
th e ve hicle body and th e tires or underneath
th e ve hicle.

Re ve rs ing camera
Fu nction of th e re ar view camera
When yo u en ga ge re ve rs e ge ar, th e image from
re ar view camera 1 is shown in th e multimedia
sy st em. Dynamic guide lines show th e path th e
ve hicle will ta ke with th e st eering wheel in its
cur re nt position. This helps yo u to orientate yo urself and to avo id obs ta cles when ba ck ing
up.
The re ar view camera is on ly an aid. It is not a
substitute fo r yo ur attention to th e sur ro undings.
Yo u are alw ay s re sponsible fo r safe maneu ve ri ng
and pa rk ing. Make sure th at th ere are no per‐
sons, animals or objects in th e maneuvering
area while maneuvering and parking in parking
spaces.

Driving and parking

In th e eve nt of a fl at tire, th e fo llowing options
are av ailable depending on yo ur ve hicle's equip‐
ment: R
Ve hicles with MOExtended tires: it is pos‐
sible to continue th e journey fo r a short
period of time. Make sure yo u obse rv e th e
no te s on MOExtended tires (run-flat tires)
( →
page 394).R
Ve hicles with a TIREFIT kit: yo u can re pair
th e tire so th at it is possible to continue th e
jou rn ey fo r a short period of time. To do th is,
use th e TIREFIT kit ( →

WA RNING Risk of accident when driving
in li mp -home mode
When driving in emergency mode th e han‐
dling ch aracteristics are impaired, e.g. when
cornering, when accelerating stro ng ly and
when braking.

If a tire pressu re of 18 0 kPa (1.8 bar/26 psi)
has been attained af te r eight minutes:
q
WA RNING Risk of accident from driving
wi th sealed tires
A tire te mp orarily sealed with tire sealant
impairs th e handling ch aracteristics and is
not suitable fo r higher speeds.

No ise or unusual handling ch aracteristics
While driving, pay attention to vibrations, noises
and unusual handling ch aracteristics, e.g. pulling
to one side. This may indicate th at th e wheels or
tires are damaged. If yo u suspect th at a tire is
defective, re duce yo ur speed immediatel y. St op
th e ve hicle as soon as possible to ch eck th e
wheels and tires fo r dama ge . Hidden tire dam‐
age could also be causing th e unusual handling
ch aracteristics. If yo u fi nd no signs of damage,
ha ve th e tires and wheels ch ec ke d at a qu alified
specialist wo rk shop.
Checking wheels and tires re gular ly
q
WA RNING Risk of accident from dam‐
aged tires
Dama ge d tires can cause tire pressure loss.
As a re sult, yo u could lose cont ro l of yo ur
ve hicle.

R
The tires may we ar exc essively and/or
une ve nl y, which may greatly impair tire
traction. R
The driving ch aracteristics, as we ll as
st eering and braking, may be greatly
impaired.

q
WA RNING Risk of accident caused by
re peated drop in tire pressure
If th e tire pressure drops re peatedl y, th e
wheel, va lv e or tire may be damaged.
Insuf fi cient tire pressure can cause th e tires
to bur st .

The tire pressure ta ble sho ws th e re commended
tire pressure fo r all tires app ro ve d fo r th is ve hi‐
cle. The re commended tire pressures apply fo r
cold tires under va ri ous operating conditions, i.e.
loading and/or speed of th e ve hicle.
If one or more tire sizes precede a tire pressure,
th e tire pressure information fo llowing is only
va lid fo r th ose tire sizes.
The load conditions "partially laden" and "fully
laden" are defined in th e ta ble fo r dif fe re nt num‐
be rs of passengers and amounts of luggage. The
actual number of seats may dif fe r from th is. Some tire pressure ta bles only show th e ri m
diame te r ins te ad of th e comple te tire size, e.g.
R18 . The ri m diame te r is part of th e tire size and
can be fo und on th e tire side wa ll ( →
