A WARNING
-
Always release the parking brake com
pletely. A partially engaged brake will
overheat the rear brakes, reduce their ef
fectiveness and cause excessive wear . This
could lead to brake failure and an accident .
(D Note
Only after the vehicle has come to com
plete stop, should you firmly set the park
ing brake and move the selector lever into
P.

.. When on inclines or declines, turn the steer
ing wheel so that the vehicle will roll into
the curb if it begins to move.
A WARNING
This is how you can reduce the risk of in
jury when leaving your vehicle.
- Never park the vehicle where it can come
in contact with dry grass, spilled fuel or
any other flammable materials.
- When parking on hills, always turn the
wheels so that the front wheels will first
roll into the curb, if the vehicle should
start to roll.
- Never allow anyone - especially small
children - to remain in the vehicle when
it is locked. Locked doors make it more
difficult for rescuers to access the pas
senger compartment in the event of an
emergency. Danger to life!
- Never leave children unsupervised in the
vehicle. Children could release the park
ing brake or move the gearshift lever out
-
of gear. The vehicle could start to roll
away and cause an accident.
- No matter what the season is, the tem
perature in a parked vehicle can reach
dangerous levels.
Q) Note
- Please exercise care when you park your
vehicle in parking areas with parking bar
riers or curbs. Parking barriers and curbs
vary in height and could damage your
bumper and related components as the
front of your vehicle moves over a barrier
or curb that is too high, as you park or as
you back out of a parking spot. In order
to be sure that no such damage can oc
cur, you may wish to stop short of having
the front tires of your car touch the park
ing barrier or curb.
- Please also exercise exceptional care
when you drive up or down steep ramps
or drive over curbs or other obstacles, for
which the vehicle is not designed, be
cause components of th@ vehicle close to
the ground, such as bumper covers,
spoilers and suspension and exhaust sys
tem components, may become dam
aged.
Starting on hills
Hill Hold makes it easier to start on hills.
The system is activated when the brake pedal
is depressed
for a few seconds . For this, the
vehicle must be standing in uphill driving di rection.
After releasing the brake pedal, the brake power is held for a
brief moment to prevent
the vehicle from rolling back when starting. At
this time, you can easily begin to move your
vehicle .

- In order to prevent the vehicle from roll
ing back unintentionally when starting in
stop-and-go traffic, keep the brake pedal
depressed for a few seconds before driv
ing off .
- When you leave the vehicle - even if only
briefly -, sw itch off the ignition and
make sure to remove the ignition key . Al

A WARNING
- Always pay attention to traffic even when
the cruise control is switched on. You are
always responsible for your speed and
the distance between your veh icle and
other veh icles .
- For safety reasons, the cruise control
should not be used in the city, in stop
and-go traffic, on twisting roads and
when road conditions are poor (such as
ice, fog , gravel, heavy rain and hydro
p laning) - risk of accident.
- Turn off the cruise control temporarily
when en ter ing turn lanes, highway exit
lanes or in construction zones .
- Please note that inadvertently "resting"
your foot on the accelerator pedal causes
the cruise control not to brake. This is because the cruise control is overridden
by the driver's acceleration.
- Never use the cruise control when driving
off-road o r on unpaved roads. The cruise
control is intended for use only when the
vehicle is being operated on paved roads,
and is not suitable for use off-road or on
unpaved roads .
(D Tips
The cruise control cannot maintain a con
stant speed when driving downhill. The ve
hicle will accelerate under its own weight .
Downshift to a lower gear or use the
brakes to slow down.

Adaptive cruise control Speed and distance
control system
Description
Applies to vehicles: with adaptive cruise cont rol
The adaptive cruise control driver assistance
program is a combined speed and distance
control system .
Fig . 12 9 Fro nt bu mper: Pos itio n of r adar se nsor (not
v is ib le from out side)
Adapt ive cruise control can he lp ma ke driv ing
more relaxed and less tiri ng , particularly dur
in g long trips on inters tates or other hig hways
that are genera lly st raight. The sys tem can al
so ass ist in stop and go traffic .
The adap tive cruise co ntrol wor ks within a
spee d range be tween 0 and 95 mph (150 km/
h ). Set ACC to maintain a constant, legal trav
e l speed between 20 and 95 mph (30 -150
km/h) that is appropriate for prevailing traff ic
conditions. Select a following distance to the
veh icle ahead and ACC will adjust your speed
to maintain that d istance down to a stop . At a
speed below 20 mph (30 km/h), the min imum
speed setting of 20 mph (30 km/h) will be se l ected a utomati ca lly.
Adapt ive cruise control has technical limita
tions that you must know, so p lease read th is
section carefully , understand how the system
wo rks and use it properly at a ll times.
How does it work?
You can operate the adaptive cruise control
usi ng the lever on the steering wheel column
c::> page 118, How is the speed stored? and
Ad apti ve crui se control 115
c::> page 120 , How is the distance (time inter
val) set? .
Driver information
Important informa tion is broug ht up in the
speedomete r an d in the instr ument clus ter
display as the vehicle is being driven
c::> page 122, Driver informat ion .
What is important for you to know
The adaptive cru ise cont ro l is set w ith system
spe cified lim its; that is, as a driver, you will
have to adjus t the speed and d istance to the
vehicle ahead in some instances
c:> page 126,
Driver intervention prompt
and c::> page 12 7,
System limitations .
A WARNING
Improper use of the adaptive cruise con
trol can cause collisions, other accidents
and se rious personal injury.
- Always remember that the adaptive cru ise contro l has limits -it will not slow
the vehicle down or ma inta in the set d is
tance when you dr ive towards an obsta
cle or someth ing o n or nea r the road that
is not mov ing, such as ve hicles stopped
in a tra ffic jam, a sta lled or d is ab led vehi
cle.
- Always remembe r that the adaptive
cru ise con tro l canno t detect a vehi cle
that is driving towards yo u in your traff ic
lane and that it cannot detect narrow
veh icles s uch as motorcycles and bicy
cles.
- Never drive at speeds that are too fast
for traffic, road and weather conditions.
- Never follow a vehicle so closely that yo u
cannot stop yo ur vehicle safely . The
adaptive cr uise control cannot s low or
brake the vehicle safely when you follow
a nother vehicle too close ly. Always re
membe r that the adaptive cruise control
has a braking powe r th at is o nly about
3 0% of the veh icle 's maxim um braking
abil ity. T he a uto mat ic br ak in g f unctio n
canno t bri ng the veh icle to a s udden or
emergency sto p. Always be prepared to

brake and take evasive action to avoid
collisions and other accident situations.
- Never allow the closing speed between
you and other vehicles to be so high that
the adaptive cruise control may not be
able to slow your vehicle safely. If clos
ing speed is too high, you must apply the
brakes yourself to reduce the risk of a
rear-end crash .
- Never rest your foot on the accelerator peda l, especia lly when the adaptive
cruise control is be ing used. Pressu re on
the accelerator w ill override the ACC
braking function and prevent the brakes
from being applied when ACC detects a situation when the brakes must be ap
plied.
- Never use adaptive cruise contro l when
you cannot drive safe ly at a steady
speed, including on city streets, on wind
ing roads or when road conditions are
poor (for example, on ice, gravel, in fog,
heavy rain or on wet roads that increase
the risk of hydroplaning) .
- The radar sensor 's
vision can be reduced
by rain, snow and heavy road spray .
T hese and sim ilar condit ions can prevent
vehicles up a head from being accurately
detected and in some cases they may not
be detected at al l. Do not use ACC when
the radar sensors cannot accurately de
tect vehicles moving ahead of yo u in traf
fic .
- Always turn off adaptive cruise contro l
when entering turn lanes , exit lanes and
construction zones or in similar situa
t ions because the vehicle will automati
cally accelerate to the stored speed when
the road ahead is clear.
- To prevent unintended operation, always
switch ACC off when it is not be ing used .
(D Tips
-For safety reasons, the stored speed is
deleted when the ignition is turned off .
- The E lectronic Stab ilizat ion Control (ESC)
i s automatically turned on when the
adaptive cruise control is turned on. You cannot switch the ESC into offroad mode
w hile the adaptive cruise contro l is
t u rned on
<=> page 224.
-Damage caused by accidents and some
mino r collisions can affect the radar sen
sor settings and cause the system to
malf unction or switch off completely.
- The radar sensor cover is heated. In win
ter conditions, you should st ill check be
fore dr iv ing to make sure it is free of ice
and snow. If necessary, clean the area
near the radar sensor carefully
<=> fig . 129 .
-To ensure that the radar sensor is not
blocked, foreign objects (e.g . stickers,
larger license plate mounts, add-on
par ts) mus t not cove r the area near the
rada r senso r<=>

has been made. If a measurement is not pos
sib le, the system cannot respond and wi ll not
react to a vehicle or someth ing else up ahead .
Open road
When the road is clear , the adaptive cru ise
control wo rks like cruise control.
It maintains
a constant target speed specified by the driv
er.
Driving in traff ic
If a slower vehicle d riving ahead is detected,

to its speed and after adjusting,
tr ies to maintain the set distance from the ve
h icle ahead. The vehicle may temporarily drive
slower than the set speed while adjusting
¢ .&. in Description on page 115 .
If the vehicle in front accelerates, adaptive
cru ise control also accelerates up to the speed
that you have set.
I f the vehicle ahead slows to a stop, ACC will
slow yo ur vehicle down and to a complete
stop if this is possible w ith in the system's lim
its and capabilities. ACC will not make an
emergency stop . The text message
ACC off:
manual control! appears in the instrument
cluster display. Once the veh icle stops, you
must dep ress the brake pedal to prevent the
veh icle from mov ing forward or "creeping" .
D epressing the brake pedal turns
off ACC.
When the vehicle ahead accelerates yo u can
reactivate ACC
¢ page 120, as soon as your
vehicle has reached a speed of 1 mph (2 km/
h) .
Situat ion s requiring dri ver int ervention
In some situations you wi ll have to use the
footbrake to s low the vehicle down in order to
k eep a safe distance from vehicle in front of
you or to avo id a rear -end coll is ion. In this sit
uation, a symbol appears and a warning tone
sounds ¢
page 126 .
Adapti ve crui se control 117
Passing another vehicle
If you move into the passing lane and no ve hi
cle is detected ahead , the adapt ive cr uise con
trol acce le rates to the speed you have set and
maintains it.
Overr iding ACC
You can in cr ease yo ur speed at a ny time by
stepping on the accelera tor ped al. A fter you
release the accelerator peda l, the system ad
justs back down to the speed you prev ious ly
set .
Reducing stopp ing distance
If the radar sensor detects that the d istan ce
to the vehicle a head is less than de fined m ini
mum distance, the brakes are automatically
prepared fo r emergency braking by the d river .
The brake pads are moved very close to the brake d iscs without actually braking the vehi
cle. This brake assistant feature reacts more
quick ly to the dr ive r's brak ing, and also works
when adapt ive cruise control is
off . The stop
ping distance is reduced as a result of th is ad
vance brake p reparation . Th is fun ction does
not perform any emergency b rak ing mane u
vers by itse lf; the dr iver mus t always apply the
brakes.
A WARNING
If ACC initiates a braking maneuver, the brake pedal w ill be retracted. Inter ference
with the brake peda l can prevent ACC from
slowing the veh icle down and cause a
crash and serious personal injury.
- Never put anything in the driver's foot
well or let anyth ing fall into it. An object
in the driver's footwe ll can inte rfe re with
the peda ls and prevent the acce le rator
from being used to override ACC or pre
vent ACC from being switched
off when
the brake pedal is depressed and also
prevent the vehicle from being slowed
down or stopped .
- Onl y use floor mats that keep the area
aroun d the peda ls free and that can be
securely fastened to the footwell .

- Always read and heed the information
and WARNINGS
¢ .&. in Description on
page 115.
A WARNING
- Never rely on the distance control fea
ture of ACC alone to prevent rear-end col
lisions . Always be prepared to brake and
take evasive action to avoid collisions and other acc ident situations.
- Never allow the clos ing speed between
yo u and other vehicles to be so h igh that
the adaptive c ruise control may not be
able to slow your vehi cle safe ly. If clos
ing speed is too high, you m ust app ly the
brakes yourself to reduce the risk of a
rear-end crash.
(D Tips
Please note that t he amo un t of a ccelera
