Stopping and applying park ing brak e
~ Pull the sw itch C®l to apply the pa rking
brake.
Starting and automatically releasing the parking brake
~ When you start to drive as usual, the park
ing brake is a utomatically released and your
veh icle begins to move.
When stopping at a traffic signal or stopping in city traff ic on vehicles with an automatic
transmission, the parking brake can be ap
plied. The vehicle does not have to be held
with the footbrake. The parking brake elimi
nates the tende ncy to creep w ith a dr ive range
engaged. As soon as you d rive off as usual,
t he pa rking bra ke is re leased automatically
and the veh icle s tarts to move.
St arting on slopes
When starting on inclines, the starting assist
prevents the vehicle from un intent io nally roll
ing back. The braking force of the parking
brake is no t re leased unt il su ff ic ient d riving

Starting off with a trailer
To prevent rolling back unintentionally on an
incline, do the follow ing:
.. Keep the switch@¢ page 70, fig. 77 pulled
and depress the accele rator. The park ing
brake stays applied and prevents the vehicle
from roll ing bac kward.
"' You can release the switch @ once you are
sure that you a re develop ing enough dr iv ing
f orce at the wheels by dep ress ing the accel
erator.
Depending on the weight of the r ig (veh icle
and tra iler) and the seve rity of the in cli ne, you
may roll backwards as you start . You can pre
vent rolling backwards by holding the parking
brake switch @ pulled out and accelerating -
just as you would when starting on a hill with a conventional hand brake.
Hill hold
Hill hold makes it easier to start on hills.
Requirement : The driver door must be closed
and the engine must be r unning .
The system is act ivated when the brake pedal
i s pressed wh ile the veh icle is sta tionary .
To prevent the vehicle from rolling back when
start ing , the brake power is held for a br ief
moment after re leas ing the b rake peda l. Dur
i ng th is t ime, yo u can easily begin to move
your ve hicle.
A WARNING
- The inte lligent technology of Hill Hold
cannot overcome the lim itations im
posed by natural phys ica l laws. The in
creased comfort offered by Hill Hold
should not cause you to take safety risks.
- Hi ll Hold cannot hold the veh icle in all
hill start situations (for examp le, if the
ground is slippery or icy).
- If you do not begin moving immediately
after releasing the brake pedal, the veh i
cle could begin to roll backward under
certai n circumstances . Press the b rake
-
pedal or set the parking brake immedi
ately .
- If the engine "stalls", press the brake
pedal or set the parking brake immedi
ately .
- Starting on inclines in stop-and-go traf
f ic: To help prevent the vehicle from roll
ing back when start ing, press and ho ld
the brake pedal for several seconds when
the vehicle is stationary.
Emergency braking
In the event tha t the conventional brake sys
tem fails or locks .
.. In an emergency, pu ll the switch @
¢
page 70, fig. 77 and continue to pull it to
slow your vehicle down with the parking
brake .
.. As soon as you release the switch @ or ac-
celerate, the b rak ing process stops.
If you pull the switch @ and hold it above a
speed of about S mph (8 km/h), the emergen
cy brak ing funct io n is initiated . T he veh icle is
braked at all fou r whee ls by activating the hy
draulic b rake system. The brake pe rfo rmance
is sim ila r to m akin g an emergency stop ¢_&. .
In order not to act ivate the eme rgency brak
ing by mistake, an audib le warning tone (buz
zer) sounds whe n the switch @ is pulled. As
soon as t he sw itch @ is re leased, or the acce l
erator pedal is depressed, eme rgency braking
stops.
A WARNING
=
Emergency braking should only be used in
an emergency, when the norma l foot bra ke
has fa iled or the brake pedal is obstructed.
Using the park ing brake to perform emer
gency braking will s low your veh icle down
as if you had made a full brake application .
The laws of phys ics cannot be suspended

Speed warning system
Overview
T he speed warning system helps you to keep
your driving speed below a set speed limit.
The speed warning system warns if the driver
exceeds a prev iously stored maximum speed .
A warning tone will sound as soon as the vehi
cle speed exceeds the set speed by about
3 mph (3 km/h). At the same time , an indica
tor lamp
(mj (USA models) / ISJ (Canada mod
e ls) will light up in the instrument cluster dis
p lay and the driver message
Spe ed limit
wa rning exceeded.
wi ll appear. The indicator
l amp
1mj / i•j will go out when the speed
drops below the set speed lim it aga in.
Setting a thresho ld is recommended if you
wou ld like to be reminded when you reach a
certain maximum speed . Situations where yo u
may want to do so include driving in a country
with a general speed limit or if the re is a
specified max imum speed for winter tires .
(D Tips
Even though your vehicle is equipped with
a speed warning system, you should st ill
watch the speedometer to make sure you are not driving faster than the speed lim it.
Setting speed limit
You can set , change and delete the threshold
in the MMI.
.,. Se lect :
I CAR I funct ion button > S ystem s or
Car System s control button > Vehicle set
tings > Speed warning .
You can set any thresho ld between 20 mph
(30 km/h) and 150 mph (240 km/h). Settings
can each be adjusted in increments of 6 mph
(10 km/h) .

Cruise control
Description
The cruise cont ro l system makes it poss ible to
drive at a constant speed start ing at 15 mph
(20 km/h).
The speed is kept constant by modifying en
gine powe r or th rough an active brake inte r
vention.
A WARNING
- Always pay attention to the traffic
around you when the cruise control is in
operation. You are always responsible for
your speed and the distance between
your vehicle and other vehicles.
- For reasons of safety, cr uise control
should not be used in the city, in stop
and-go traffic, on winding roads and
when road cond it ions are poor (such as
ice, fog, gravel, heavy rain and hydro
plan ing) -you could have an accident .
- Sw itch the cruise control off temporar ily
when dr iv ing in turning lanes, h ighway
exits or in constr uction zones.
- Please note that unconsc iously "resting"
your foot on the accelerator pedal pre
vents the cruise control from braking .
This is due to the control system be ing
overridden by the dr iver's acceleration .
- If a b rake system malfunction s uc h as
overheating occurs when the cruise con
trol system is swi tched on, the braking
function in the system may be switched off . The other cruise control functions re
main active as long as the indicator light
II (US models) !l'I (Canada mode ls) is
on .
(D Tips
-The cruise control system is ideal for
stretches w ith speed limits. The driver is
responsib le for adhering to the correct
speed.
- The cru ise control remains act ive when
