Emergency brake function
An emergency brake ensures that the vehicle
can be slowed down even if the
normal brakes
fail c::>
page 72, Emergency broking.
& WARNING
If a drive range is engaged with the vehicle
stat ionary and the engine running, you
must in no instance accelerate care lessly.
Otherw ise the vehicle will start to move
immediately -risk of an accident.
(D Tips
- If the parking brake is applied with the
i gnition switched off, the indicator lights
• in the switch and. (USA models) /
• (Canada models) in the instrument
cluster w ill go out after a certa in period
of time.
- Occasional noises when the park ing
brake is applied and re leased a re norma l
and are not a ca use for concern.
- When the vehicle is parked, the parking
brake goes through a se lf-test cycle at
regular intervals. Any assoc iated noises
are norma l.
Parking
~ Press the brake peda l to stop the vehicle.
~ Pull the switch@c::> page 70, fig . 77 to set
the parking brake.
~ Move the selector lever to P.
~ Turn the engine off c::> _&.
~ When on incl ines or declines, turn the steer
ing wheel so that the vehicle w ill roll i nto
the curb if it begi ns to move.
& WARNING
- When you leave your veh icle - even if on
ly b riefly- a lways remove the ign ition
key . This applies particularly when chil
dren remain in t he vehicle . Otherwise the
children co uld start the engine, release
the parking brake or operate electrical
equipment (e.g. power windows). There is the r isk of an accident .
On th e ro ad 71
-When the veh icle is locked, no one - par
ticularly not children should rema in in
the vehicle. Locked doors make it more
difficult for emergency wo rkers to get in
to the vehicle - putting lives at risk .
Starting from rest
The starting assist function ensures that the
parking broke is released automatically upon starting.
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
force has been built up a t the wheels.
(D Tips
Fo r safety reasons, the parking bra ke is re
l eased automatically o nly when the d riv
e r's safety belt is eng aged in the buckle.

72 On the road
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

Child safety seats
Infant seats
Babies and infants up to about one year old
and 20 lbs. or 9 kg need special rearward -fac
ing child restraints that support the back,
neck and head in a crash.
Fig . 126 Sche mati c overv iew: rearward-fac ing infa nt
seat, p roperly installed o n th e rear seat
.,. When using the vehicle safety belt to install
a ch ild safety seat , you must first activate
the convertible locking retracto r on the
safety be lt to prevent the child safety seat
from moving
r=;, page 143 or install the seat
using the LA T CH attachments.
.,. Push the child safety seat down with your
full weight to get the safety belt rea lly tight
so that the seat cannot move forward or
sideways more than one inch (2.5 cm) .
.,. Secure unused safety belts on the rear seat
¢ page 138.
Infants up to about one year (20 lbs . or 9 kg)
are best protected in special infan t carriers
and child safety seats designed for their age
group . Many experts believe that infants and
small children should ride only in spec ial re
straints in which the ch ild faces the back of
the vehicle. These infant seats support the ba
by's back, neck and head in a crash
¢ fig . 126.
The airbag on the passenger side makes the
front seat a po tentially dangerous place for a
child to r ide . The front seat is not the safest
p lace for a child in a forward -facing child seat.
It is a very dangerous p lace for an infant or a
l arger ch ild in a rearward-facing seat.
Child S afety 139
A WARNING
Not using a child safety seat, using t he
wrong child safety seat or improperly in
stall ing a ch ild restraint increases the risk
of ser ious personal injury and death in a
crash.
- Never install rear-facing child safety
seats or infant ca rr ie rs on the front pas
senger seat -even with an Advanced Air
bag Sys tem. A c hild will be ser iously in
jured and ca n be killed when the inflat
ing airbag hits the child safety seat or in
