capacity is limited by tire traction. You
should therefore not drive at excessive
speeds on icy or slippery road surfaces.
- On wet road surfaces, be careful not to
dr ive too fast because the front wheels
cou ld beg in to slide on top of the water
(aquaplaning) . If this should occur, you
will have no warning from a sudden in­
crease in engine speed as with a front·
wheel drive vehicle . A lways d rive at
speeds wh ich are suited to the road con­
ditions -risk of crash.
Energy management
Starting ability is optimized
Energy management controls the distribution
of electrical energy and thus optimi zes the
availabili ty of electrical energy for s tarting
the engine .
If a vehicle with a conventional energy system
is not driven for a long period of time, the bat­
tery is discharged by idling current consumers
(e .g . immobilizer) . In certain c ircumstances it
can result in there being insufficient energy
avai lab le to start the engine.
Intell igent energy management in your vehi­
cle hand les the d istribution of electrical ener ·
gy. Starting ab il ity is markedly improved and
the life of the battery is extended .
Basically, energy management consists of
battery diagno sis, idling current manag e­
m ent
and dynamic en erg y manag ement.
B attery diagnosi s
Battery diagnosis continuously determines
the state of the battery. Sensors determ ine
battery vo ltage, battery current and battery
temperature . This determ ines the current
state of charge and the powe r of the battery.
Idling current management
Idling current management reduces energy
consumption while the vehicle is s tand ing.
W ith the ignition switched off, it contro ls the
energy supply to the various electr ica l compo·
Int ellig ent technolog y 177
nents . Data from batte ry diagnos is is cons id ­
ered.
Depend ing o n the ba ttery's state of cha rge ,
individ ua l cons umers are g radually turned off
to prevent excessive discharge of the battery
and t hus maintain sta rting capability.
Dynamic energy management
While t he vehi cle is being d riven, dynamic e n­
ergy ma nagement dis trib utes the energy ge n­
era ted accord ing to the needs of the individ u­
al components. It regulates consumption, so
that more e lectrical energy is not bei ng used
than is being generated and ensures an opti­
mal state of charge for t he battery.
(D Tips
- But even ene rgy management cannot
negate the limits of physics. Consider
that the power and life of a battery are
limited.
- If start ing ability is threatened, the indi­
cator light (•) ::ippears

What you should know
The highest priority is given to maintaining
star ting capability.
The battery is severe ly taxed in short-distance
driving, in city traff ic and during the cold time
of year. Ab undant electrica l energy is re­
quired, but on ly a little is generated . It is also
critical if the engi ne is not running and electri­
ca l components are turned on . In this in ­
stance ene rgy is be ing consumed but none is
being ge nerated .
It is in precisely these situations that you will
notice energy management active ly regu lat ·
ing the d istribut ion of energy .
Vehicle stands for an extended period
If you do not drive your vehicle over a period
of several days or weeks, e lectr ica l compo­
nents are gradually cut back or switched off.
This reduces energy consumption and ma in·
ta ins start ing capability over a longer period .

the car wash operator to reduce the risk of accidents .
- To reduce the risk of cuts, protect your­
self from sharp metal components when
wash ing the underbody or the inside of
the wheel housings .
- After washing the vehicle, the braking ef­
fect may be delayed due to mo isture on
the brake rotors or ice in the winter. The
brakes must be dried first with a few
careful brake applicat ions.
- If you wash the vehicle in an automatic car wash, you must fold the exterior m ir­
rors in to reduce the r is k of damage to
the mirrors. Power folding exterior m ir­
rors* must only be folded in and out us­
i ng the power folding function. -

24 0 T ire s and wheel s
According ly, when the low tire pressure te ll­
tale illuminates, you shou ld stop and check
your tires as soon as possible, and inf late
them to the proper pressure. Driving on a s ig­
n ificantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-in­
flation also reduces fuel efficiency and tire
tread life, and may affect the vehicle's han­
dli ng and stopp ing ability.
Please note that the TPMS is not a subst itute
for proper tire maintenance, and it is the driv­
e r's responsib ility to ma inta in correct tire
p ressu re, even if under- inflation has not
reached the leve l to trigger ill umination of the
TPMS low tire pressure telltale.
Your veh icle has also been equ ipped with a
TPMS malfunction indicato r to indica te when
the system is not opera ting properly. The
TPMS mal function indicator is combined wi th
the low tire press ure telltale . When the sys­
tem detects a malfunction, the te lltale will
f lash fo r approximately one minute and then
remain cont inuous ly illuminated. This se­
quence will continue upon subsequen t vehicle
start -ups as long as the ma lfunction ex ists .
When the malfunct ion indicator is ill uminat­
ed, the system may not be able to detect or
signal low t ire pressure as intended . TPMS
malfunctions may occur for a variety of rea ­
sons , includ ing the installat ion of replace­
ment or a lternate tires or whee ls on the veh i­
cle that prevent the TPMS from funct ioning
p roperly. Always check the TPM S malf unct ion
tellta le after replacing one o r more t ires or
wheels on your veh icle to ensure that the re­
p lacement or a lternate tires and wheels allow
the TPMS to continue to function p roperly. Tire pressure indicator appears
Applies to vehicles: wit h tire press ure mo nitor ing system
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too
low or if there is a system malfunction .

U sing the ABS sensors, the tire pressure moni­
toring system compares the tire tread circum ­
ference and vib ration characteristics of the in­
dividua l tires.
If the pressure decreases in one
or more t ires, this is indicated in the instru­
ment cluster with a
RI] war ning symbol and a
message ¢
fig. 187 . The driver message in the
display goes out afte r 5 seconds . The driver
message can b e displayed again by pressing
t h e
ISE TI button. If o nly one t ire is affec ted,
the d isp lay w ill indicate its posi tion.
The tire pressure monitoring system must be reset via rad io or M MI* each time the pres­
su res a re adjusted (e.g. when swit ching be­
tween partial and f ull load p ress ure) or after
changing or rep lacing a tire on your ve hicle
¢
page 241 . The TPMS indicator only mon i­
tors the ti re pressure that yo u have previous ly
stored. You can find the recommended tire
pressures for your vehicle on the label on driv­
er 's side 8-pillar ¢
page 217.
Tire tread circumference and vibration charac­
teristics can change and cause a ti re pressure
warning if:
- the tire press ure in one or more tires is too
low,
- the t ire has struc tural damage,
- t he t ire p ress ure was c hanged, wheels rota t-
ed or rep laced but the TPMS was not reset

Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the right direction.
Using a replacement tire with a tre ad
patte rn intend ed for us e in a specific
directi on
When us ing a replacement t ire with a tread
pattern intended for use in a specific direc­
tion, please note the fo llowing:
- T he direction of rotation is marked by an
ar ­
row on th e side of the tire.
- If the replacement tire has to be installed in
t h e incorrect d irection, use the tire only
temporarily since the tire will no t be able to
achieve its optimum performance character­
istics with regard to aquaplaning, noise and
wear .
- We recommend that you pay particular at­
tention to this fact during wet weather and
that you adjust your speed to match road conditions.
- Replace the flat tire with a new one and
have it installed on your veh icle as soon as
poss ible to restore the handling advantages
of a unid irect ional tire.
Notes on wheel changing

even a flat tire and the jack and tool kit
are properly secured in the luggage com­
partment and are not loose in the pas­
senger compartment.
- In an accident or sudden maneuver they
co uld fly forwa rd, injuring anyone in the
veh icle.
- Always sto re damaged wheel, jack and
too ls securely in the luggage compa rt­
men t. Othe rwise, in an accident or s ud ­
den maneuver they co uld f ly forward,
causing injury to passengers in the vehi ­
cle.
