Moving
away with optimised acceleration &
WARNING Risk of skidding and having
an accident from wheels spinning
When you use optimised acceleration, indi‐
vidual wheels could spin and you could lose
cont rol of theve hicle.
If ESP ®
is deactivated, there is a risk of skid‐
ding and accident! #
Make sure that no persons or obstacles
are in the close vicinity of your vehicle. Re
quirements:
R theve hicle is run in (/ page 191).
R theve hicle and tyres are in good condition.
R you are on a high-g rip ro adw ay.
R the engine and transmission are at normal
operating temp erature. *

TEIncreased wear due tooptimised
acceleration When pulling
away with optimised accelera‐
tion, all components of the driv etra in are
subjected toave ry high load.
This can lead toinc reased component wear. #
Do not alw ays pull away with optimised
acceleration. #

Depress and hold the brake pedal firm ly wi th
yo ur left foot. #
With your right foot , fully depress the accel‐
erator pedal. #
After no more than five seconds, take your
left foot quickly off the brake, but keep the
accelerator pedal depressed.
The vehicle pulls away at maximum accelera‐
tion. #
Swit chon ESP ®
once the acceleration proce‐
dure is comple te.
Ending optimised acceleration #
Remo veyour foot from the accelerator pedal. #
Reactivate the ESP ®
.
% Afteryo u pull away with optimised accelera‐
tion, components of the driv etra in can
become very hot, which means that opti‐
mised acceleration values may be reached
again on lyafte r a few minutes. Note

WARNING Risk of accident if the ignition
is switched off while driving
If yo u swit choff the ignition while driving,
saf ety functions are restricted or no longer

DANG ER Risk of death caused by
ex haust gases
Combustion engines emit poisonous exhaust
ga ses such as carbon monoxide. Inhaling
th ese exhaust gases is hazardous tohealth
and leads topoisoning. #
Never lea vethe engine or, if present,

WARNING Risk of skidding and of an
accident due toshifting down on slippery
ro ad sur faces
If yo u shift down on slippery road sur faces to
inc rease the engine braking ef fect, the drive
wheels may lose traction. #
Do not shift down on slippery road sur‐
fa ces toinc rease the engine braking
ef fect. &
DANG ER Risk of fata l injury due topoi‐
sonous exhaust gases
If th eta ilpipe is bloc ked or suf ficient ventila‐
tion is not possible, poisonous exhaust gases
such as carbon monoxide may enter theve hi‐

WARNING Risk of accident due tothe
brake sy stem overheating
If yo u lea veyour foot on the brake pedal
when driving, the brake sy stem may over‐

s on driving with a roof load, trailer or
ful lyladen vehicle
When driving with a loaded roof luggage rack or
trailer as well as with a fully laden or fully occu‐
pied vehicle, theve hicle's driving and steering
ch aracteristics change.
Yo u should bear thefo llowing in mind:
R Do not exceed the permissible roof load and
to wing capacity. Also obser vethete ch nical
da ta inthe printed Owner's Manual.
R Evenly distribute thero of load, and place
heavy objects at the bottom. Also comply
with the no tes on loading theve hicle
(/ page 134).
R Drive attentivel y,and avoid sudden lypulling
aw ay, braking and steering as well as rapid
cornering. 194
Driving and pa rking

Note
s on driving on salt-treated roads
The braking ef fect is limited on salt-trea ted
ro ads.
Therefore, obse rveth efo llowing no tes:
R due tosalt build-up on the brake disks and
brakepads, the braking dis tance can increase
considerab lyor result in braking only on one
side
R maintain a much greater safe dis tance tothe
ve hicle in front
To remo vesalt build-up:
R brake occasionally while paying attention to
th e tra ffic conditions
R carefully depress the brake pedal at the end
of the journey and when starting the next
journey
Note s on aquaplaning
Aq uaplaning can take place once a cer tain
amount of water has accumulated on thero ad
sur face. Obser
vethefo llowing no tes during heavy precip‐
itation or in conditions in which aquaplaning may
occur:
R reduce speed
R avoid tyre ruts
R avoid sudden steering mo vements
R brake carefully
% Also obser vethe no tes on regular lych ecking
wheels and tyres (/ page 383).
Note s on driving through water on the road
sur face
Wa ter which has entered into theve hicle can
damage the engine, electrics and transmission.
Wa ter can also enter the air intake of the engine
and cause engine damage.
Obser vethefo llowing if you must drive thro ugh
wate r:
R The water,when calm, may only reach the
lo we r edge of theve hicle body.
R Drive at a maximum speed of 10km/h;
wate r can otherwise enter theve hicle interior
or engine compartment. R
Vehicles tr avelling in front, or oncoming vehi‐
cles, can create waves which may exceed the
maximum permissible dep thofthewate r.
The braking ef fect of the brakes is reduced af ter
fo rd ing. Brake carefully while paying attention to
th e tra ffic conditions until braking po wer has
been fully restored. Fu
nction of rear axle steering The
rear axle steering is an electromechanical
auxiliary steering on there ar axle which adjusts
th esteering of there ar wheels according tothe
position of the front wheels, depending on the
speed. This results in greater manoeuvrability
and impr oved driving stabilit y,e.g. when corner‐
ing.
Re ar axle steering has thefo llowing characteris‐
tics:
R reduced steering ef fort and turning circle

fo llowing situations if all vehicle conditions for
an automatic engine stop are me t:
R You brake theve hicle toast andstill in trans‐

R Vehicles with a 48 V on-board electrical
sy stem: You depress the brake pedal when
tra velling at a low speed. If
th e sy stem has de tected one of thefo llowing
situations, the engine will not stop:
R Youstop at a stop sign and there is no vehi‐
cle in front of you.
R The vehicle that stopped in front of you
st arts up again.
R You manoeuv re, turn thesteering wheel
sharply or engage reve rsege ar.
% Ifth e sy stem de tects an intelli gent stop
inhibitor, forex ample, a stop sign, the engine
will not stop.
If yo u activate the HOLD function or engage
th e park position j,the engine can be
switched off in spite of an intelligent stop
inhibitor.
The engine is restar ted automatically if:
R You en gage transmission position hork.
R You depress the accelerator pedal.
R An automatic engine start is requiredbythe
ve hicle.
R Youre lease the brake pedal. R
Vehicles with a 48 V on-board electrical
sy stem:
- Youre lease the brake pedal on a downhill
gradient and theve hicle does not roll.
- The vehicle rolls on a downhill gradient
and does not automatically enter glide
mode at 20 km/h.
