Checklist after driving off-road
!If you detect damagetothevehicle after
driving off-road, have th evehicle checked
immediately at aqualified specialist work-
shop.
Off-road driving places ahigher demand on your
vehicle than normal road operation. Checky our

XClean th eheadlamps and tail lamps and
check them for damage.
XClean th efront and rear licens eplates.
XClean th ewindshield, windows and exterior
mirrors.
XClean th esteps, door sills and grab handles.
This increases safety of footing.

Driving in mountainous areas
When driving in mountainous areas ,notet hat
th ep ower output of th eengine, and withiti ts
gradientc limbingcapability, decreas ewith
increasing altitude. Pleaset aken oteoft hisp ar-
ticularly when driving withat railer in mountain-
ous areas.
The maximum permissible trailer loads are valid

Important safety notes
Observe the notes on braking (Ypage 136).
If yo ufailtoa dapt your driving style or if yo uare
inattentive ,cruise control can neither reduce
the ris kofana ccident nor override the laws of
physics .Cruise control canno ttake road,
weathe rand traffic conditions into account.
Cruise control is only an aid. Yo uare responsible
for the distance to the vehicl einfront, for vehi-
cle speed, for braking in goo dtime and for stay-
ing in lane.
If yo uchange wheel size ,make sure they corre-
spond to the correct wheel size category
(
Ypage 267). If the categor yischanged without
recoding the control units in the vehicle, the
functioning of cruise control may be impaired.
Do not us ecruise control:
Rin traffic conditions that are unsuitable for
driving at aconstant speed, e.g. in heavy traf-
fic, on winding roads or off-road.
Ron slippery roads. Braking or accelerating
may cause the drive wheel stoloset raction
and the vehicl ecould then skid.

Storing and maintaining the current
speed
XAccelerate the vehicle to the desired speed
above 20 mph (30 km/h).
XBriefly push the cruise control lever up:or
down =.
XRelease the accelerator pedal.
Cruise control is activated. The current speed
is stored and shown briefly in the display's
text field.
The display also shows the Vsymbol and
the stored speed:

wheel buttons (Ypage 176)
Resuming the stored speed
GWARNING
If you call up the stored speed and it differs
from the current speed, the vehicle acceler-
ates or decelerates. If you do not know the
stored speed, the vehicle could accelerate or brake unexpectedly. There is arisk of an acci-
dent.
Pay attention to the road and traffic condi-
tions before calling up the stored speed. If you
do not know the stored speed, store the
desired speed again.
XBriefly pull the cruise control lever towards
you ;.
XRelease the accelerator pedal.
Cruise control is activated and resumes the
vehicle's speed to the last speed stored.
The stored speed is shown briefly in the dis-
play.
The display also shows the Vsymbol and

iWhen you pull the cruise control lever
towards you for the first time after startin gthe
engine, cruise control adopts the current
speed.
Setting the speed
It may be amoment before the vehicle starts to
accelerate or brake to the set speed. Take this
delay into account when settingt he speed.
XPress the cruise control lever up:to
increase the speed or down =to reduce the
speed.
The vehicle will accelerate or decelerate. The
speed is shown in the display.
XRelease the cruise control lever once the
desired speed is reached.
The displayed speed is stored.
or
XBriefly press the cruise control lever as far as
the 1st pressure point up :or down =.
The last speed stored is increased/reduced in increments of 1mph (1 km/h).
or
XBriefly press the cruise control lever beyond
the pressure point up :or down =.
The last speed stored is increased/reduced in increments of 5mph (10 km/h).
iCruise control is not deactivated if you
depress the accelerator pedal. If you acceler-
ate briefly to overtake, for example, cruise
control resumes the vehicle’s speed to the
last speed stored after you have finished over-
taking.
To deactivatec ruise control
There are various ways to deactivate cruise con-
trol:
XBriefly press the cruise control lever for-
wards?.
or
XApply the brakes.
The last speed set remains stored. The last
speed stored is deleted when you switch off the
engine.
Cruise control is deactivated automatically

PARKTRONIC
General notes
PARKTRONIC is an electronic parking aid. The
system is equipped with ultrasonic sensors in
the front and rear bumpers to monitor the area
around your vehicle. PARKTRONIC indicates vis-
uallya nd audibly the distance between your
vehicle and an object.
Your vehicle features two separate sound emit-
ters with different frequencies for the warning
tones. The warning ranges in front of and behind the vehicle are indicated by different warning
tones.
PARKTRONIC is activated automatically when
you:
Rturn the key to position 2in the ignition lock
Rrelease the parking brake and
Rmove the selector lever to D,Nor R
PARKTRONIC is deactivated at speeds above
11 mph (18 km/h). PARKTRONIC is reactivated
at speeds below 10 mph (16 km/h).
Important safety notes
PARKTRONIC is only an aid. It cannot replace
your own awareness of the immediate surround-
ings. You are responsible for safe maneuvering,
parking and pulling away.W hen maneuvering,
parking and pulling away,m ake sure that there
are no persons, animals or object sinthe maneu-
vering area.
!Pay particular attention to obstacles above
or below the sensors when parking, such as
flower pots or trailer towbars. PARKTRONIC
does not recognizes uch objectswhen they
are in the immediate vicinity of the vehicle.
You could damage the vehicle or objects.
PARKTRONIC can suffer interference from:
Rultrasonic sources such as atruck's
compressed-air brakes, an automatic car
wash or apneumatic drill
Rattachments to the vehicle, e.g. rear moun-
ted racks
Rnumber plates (vehicle license plates) that
are not affixed flat against the bumper
Rdirty or icy sensors
Remove adetachable trailer coupling if it is no
longer required. PARKTRONIC measures the
minimum detection range to an obstacle from
the bumper, not the ball coupling.

Active Parking Assist no longer supports you
with steering interventions and brake applica-
tions. Once active parking assistance has been
stopped, you must steer and brake again your-
self. PARKTRONIC is still available.
Parking tips:
RThe way your vehicle is positioned in the park- ing space after parking is dependent on vari-
ous factors. These include the position and
shape of the vehicles parked in front and
behind it and the conditionsoft he location. It
may be the case that Active Parking Assist
guides you too far into aparking space, or not
far enough into it. In some cases, it may also
lead you across or onto the curb. In this case,
cancel the active parking assistance.
RYou can also preselect transmission position
D.T he vehicle redirects and does not drive as
far into the parking space. If you change direc-
tion too early, parking assistance is canceled
and Active Parking Assist is stopped. It is then
not possible to achieve asensible parking
position from the current position.
Exiting aparking space
In order that Active Parking Assist can support
you when you exit the parking space:
Rthe border of the parking space must be high
enough at the front and the rear. Acurb is too
small, for example.
Rthe border of the parking space must not be
too wide. Your vehicle can be maneuvered
into aposition at amaximum of 45° to the
startin gposition in the parking space.
Ram aneuvering distance of at least 3.3 ft
(1.0 m) must be available.
Active Parking Assist can only assist you with
exiting aparking space if you have parked the
vehicle parallel to the direction of travel using
Active Parking Assist.
If PARKTRONIC detects obstacles, Active Park-
ing Assist brakes automatically when exiting
from the parking space. You are responsible for
