Stopping the engine
Applies to: vehicles with ig ni tion lock
.. Bring the vehicle to a full stop .
.. Automatic transmission: Move the selector lev­
er to the P or N position .
.. Press on the ignition key. The engine is turned
off.
.. You can now remove the key .
Steering lock
The steering locks when you remove the ignition
key. The locked steering helps prevent vehicle
theft.
Emergency off
If it is necessary in unusual circumstances , the
engine can be switched off while the vehicle is
moving . The engine will be switched off if you
press on the key for an extended period.
A WARNING ,-
- Never turn off the engine before the vehicle
has come to a complete stop. The full func­
tion of the brake booster and the power
steering is not guaranteed. You must use
more force to turn or brake if necessary . Be­
cause you cannot steer and brake as you
usually would, this could lead to crashes
and serious injuries.
- For safety reasons, you should always park
your vehicle with the selector lever in P.
Otherwise, the vehicle could inadvertently
roll away .
Driving
-The radiator fan can continue to run for up
to 10 minutes even after you have turned
off the engine and removed the ignition key.
The radiator fan can also turn on again if the
engine coolant heats up because of intense
sunlight or heat build-up in the engine com­
partment.
- Always take the key with you whenever you
leave your vehicle. Otherwise, the engine
could be started or electrical equipment
such as the power windows could be operat­
ed. This can lead to serious injury.
- Never leave children or persons requiring as­
sistance unattended in the vehicle. The
doors can be locked using the remote trans­
mitter, preventing people from escaping
from the vehicle on their own in the event of an emergency. Depending on the time of
year, people inside the vehicle can be ex­ posed to very high or very low tempera ­
tures .
(D Note
If the engine has been under heavy load for
an extended period, heat builds up in the en­
gine compartment after the engine is switch ­
ed off -there is a risk of damaging the engine.
Allow the engine to run at idle for about two
minutes before switching it off.

Operation
The electromechanical parking brake replaces
the hand brake.

parking brake . The ind icator lights in the switch
and . (USA
models) ;II (Canada models) in
the instr ument cluster illum inate.
~ With the ign ition switched on, step on the
brake peda l or the acce lerato r pedal and press
t he switch @at the same t ime to re lease the
parking brake . The indicator lights in the switch
and . (USA
models) ;II (Canada models) in
the instr ument cluster go o ut.
Your ve hicle is equipped wi th an elec tromechani ­
cal parking b rake. The park ing brake is designed
to prevent the vehicle from rolling un intent ional­
ly and rep laces the hand brake .
I n addition to t he norma l func tions of a tradi ­
tional hand brake, the electromecha nica l park ing
b rake provides various convenience and safety
functions.
When starting from rest
- T he integ ral s tart ing assist helps you when
driv ing by a utomat ically releasing the park ing
brake ¢
page 77, Starting from rest .
-When starting on in cli nes, the sta rting assist
prevents the vehicle from unintentiona lly roll ­
ing back . The braking forc e of the park ing b rake
is not released until sufficient drivi ng force has
been built up at the wheels.

A WARNING
-
If a drive range is e ngaged w ith the vehicle
stationary and the engine running, you must
i n no instance accelerate careless ly. Other­
wise the veh icle w ill start to move immediate­
ly -risk of an accident.
(D Tips
- If the park ing brake is applied with the igni­
t ion switched off, the indicator lights in the
switch and -(USA mode ls)/ . (Cana­
da models) in the instrument cluster w ill go
o ut after a certai n pe riod of time.
- Occasional noises when the pa rking brake is
applie d and released are normal and are not
a ca use for conc ern.
- Whe n the vehicle is parked, the parking
brake goes through a self-test cycle at regu­
lar intervals. Any associated noise s are nor­
m al.
Parking
~ Press the bra ke peda l to stop the ve hicle.
~ Pull the switch@¢ page 76, fig. 91 to set the
parking bra ke .
~ Move the se lector lever to P.
~ T urn the engine off¢.&,. .
~ When on inclines or decl ines, turn the steer ing
wheel so that the vehicle will ro ll into the curb
if it begins to move .
.&_ WARNING
-W hen you leave yo ur vehicle -even if only
b riefly- always re move t he igni tion key. This
app lies p art ic ula rly when children remain in
the vehicle. Ot herwise the children could
start the e ngine, re lease the parking brake
or operate electrica l equipment (e .g. power
w indows) . The re is the r isk of an accident.

-When the vehicle is locked, no one - part icu­
larly not children should remain in the vehi­
cle. Locked doors make it more diff icu lt for
emergency workers to get into the vehicle -
putt ing lives at risk.
Starting from rest
The starting assist function ensures that the
parking brake is released automatically upon
starting .
Stopping and applying parking brake
~ Pull the switch @9 page 76, fig. 91 to apply
the parking brake.
Starting and automatically releasing the
parking brake
~ When you start to drive as usual, the parking
brake is automatica lly released and your vehicle
begins to move.
When stopping at a traffic signal or stopping in
city traffic on vehicles w ith an automatic trans­
miss ion, the park ing brake can be applied. The
vehicle does not have to be held with the foot­ brake . The park ing brake eliminates the tendency
to creep with a drive range engaged. As soo n as
you dr ive off as usual, the parking brake is re­
leased automatically and the veh icle starts to
move.
Starting on slopes
When starting on inclines, the start ing assist pre ­
vents the vehicle from unintentionally rolling
back. The braking force of the parking brake is
not released until sufficient driving force has
been built up at the wheels.
(D Tips
For safety reasons, the parking brake is re­
leased automatically only when the driver's
safety belt is engaged in the buckle.
Driving
Starting off with a trailer
To prevent rolling back unintentionally on an in­
cline, do the following:
~ Keep the switch @9 page 76, fig. 91 pulled
and depress the accelerator. The parking brake
stays applied and prevents the vehicle from
rolling backwa rd .
~ You ca n release the sw itch @once you a re sure
that you are develop ing enough dr iv in g force at
t he wheels by depressing the accelerator.
Depending on the weight of the rig (vehicle and
trailer) and the severity of the incline, you may
roll backwards as you start. You can prevent roll­
i ng backwards by holding the pa rking brake
swi tch @ pulled out and accelerating -just as
you wou ld when starting on a hill with a conven­
t iona l hand brake .
Emergency braking
In the event that the conventional broke system
foils or locks.
~ I n an emergency, pull the switch@Q page 76,
fig. 91 and continue to pull it to slow your vehi ­
cle down with the parking brake.
~ As soon as you re lease the switch @or acceler-
ate, the braking process stops .
If you pull the switch @and hold it above a
speed of about 5 mph (8 km/h), the emergency
braking f unction is init iated. The vehicle is braked
at all four whee ls by activating the hydraulic
brake system . The brake performance is s imilar
to making an emergency stop
Q .& .
In order not to activate the emergency braking by
mistake, an audible warning tone (buzzer)
sounds when the switch @is pulled . As soon as
the switch @ is released, or the accelerator pedal
i s depressed, emergency braking stops .
A WARNING
Emergency braking should only be used in an
emergency, when the normal foot bra ke has
failed or the brake pedal is obstructed. Using
the parking brake to perform emergency
braking w ill slow your vehicle down as if you

At speeds above about 1 mph (2 km/h) the Auto­
matic Shift Lock is automatically deactivated in
the N position.
A time delay element prevents the selector lever
from locking when it is moved through the N po­
sition (going from R to D/S). The locking e lement
will lock the se lector lever if the lever is left in N
(Neutral) for more than approx imately 2 sec­

The release button on the se lector lever prevents
the lever from being accidentally sh ifted into cer­
