Driving
oil pressure must first build up in the hy­
draulic valve adjusters. This is normal and not a cause for concern.
- If you leave the vehicle with the ignition
switched on, the ignition will switch off af­
ter a certain period of time. Please note that
electrical equipment such as exterior lights
will switch off as well when that happens .

Steering lock
The steering locks when you turn the engine off
using the
I START E NGINE STOP ! button and
open the driver's door. The locked steering helps
prevent vehicle theft.
Emergency off
If necessary, the engine can be switched off with
the selector lever in the R or D/S positions . The
engine stops if you press and hold the
I STAR T ENGIN E STOPI button at speeds below
6 mph (10 km/h) and press the brake pedal.
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 .
- 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
84
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.
(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.

Your vehicle is equipped with an electromechani­
cal park ing brake. The parking brake is designed
to prevent the vehicle from rolling un intent ional­
ly and replaces the ha nd b rake .
In add ition to the normal functions of a trad i­
t ional ha nd brake, the electromechanical parking
brake prov ides va rious conven ience and safety
funct ions.
When starting from rest
- The integral starting assist helps you when
driving by automatically releas ing the parking
brake ~

Driving
- Occasional noises when the parking brake is
applied and released are normal and are not
a cause for concern.
- When the vehicle is parked, the parking
brake goes through a self-test cycle at regu­
lar intervals. Any associated noises are nor­
mal.
Parking
.,. Press the brake pedal to stop the vehicle .
.,. Pull the switch @¢
page 85, fig. 100 to set
the parking brake.
.,. Automatic transmission: Move the selector lev-
er to P.
.. Turn the engine off¢.&, .
.. Manual transmission: Shift into 1st gear.
.. When on inclines or declines, turn the steering
wheel so that the vehicle will roll into the curb
if it begins to move.
A WARNING
-
-When you leave your vehicle -even if only
briefly -always remove the ignition key. This
applies particularly when children remain in
the vehicle. Otherwise the children could
start the engine, release the parking brake
or operate electrical equipment (e.g. power
windows). There is the risk of an accident.
- When the vehicle is locked, no one -particu­
larly not children should remain in the vehi­
cle. Locked doors make it more difficult for
emergency workers to get into 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 parking brake
.. Pull the switch @¢ page 85, fig. 100 to apply
the parking brake.
86
Starting and automatically releasing the parking brake
.. When you start to drive as usual, the parking
brake is automatically released and your vehicle
begins to move.
When stopping at a traffic signal or stopping in city traffic on vehicles with an automatic trans­
mission, the parking brake can be applied. The
vehicle does not have to be held with the foot­ brake. The parking brake eliminates the tendency
to creep with a drive range engaged . As soon as
you drive off as usual, the parking brake is re­ leased automatically and the vehicle starts to
move .
Starting on slopes
When starting on inclines, the starting 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.
Starting off with a trailer
To prevent rolling back unintentionally on an in­
cline, do the following:
.. Keep the switch @¢ page 85, fig . 100 pulled
and depress the accelerator. The parking brake
stays applied and prevents the vehicle from
rolling backward.
.,. You can release the switch @once you are sure
that you are developing enough driving force at
the 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
ing backwards by holding the parking brake
switch @pulled out and accelerating -just as
you would when starting on a hill with a conven­
tional hand brake .

Emergency braking
In the event that the conventional brake system
fails or locks.
11-In an emergency, pull the switch @c:> page 85,
fig. 100
and continue to pull it to slow your ve­
hicle down with the parking brake.
11-As soon as you release 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 function is initiated. The vehicle is braked
at all four wheels by activating the hydraulic
brake system. The brake performance is similar
to making an eme rgency stop c:>
.&..
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
is depressed, emergency braking stops.
A WARNING
Emergency braking should only be used in an
emergency, when the normal foot brake has
failed or the brake pedal is obstructed. Using the parking brake to perform emergency
braking will slow your vehicle down as if you
had made a full brake application. The laws of
physics cannot be suspended even with ESC
and its associated components (ABS, ASR,
EDS). In corners and when road or weather
conditions are bad, a full brake application
can cause the vehicle to skid or the rear end to
break away- risking an accident.
Speed warning system
Overview
The speed warning system helps you to keep your
driving speed below a set speed limit.
The speed warning system warns if the driver ex­
ceeds a previously stored maximum speed. A
;:; warning tone will sound as soon as the vehicle
0 ~ speed exceeds the set speed by about 3 mph
~ (3 km/h). At the same time, a warning symbol Lil ,...., v:, ,....,
Driving
appears in the display. The symbol's appearance
might be different in some models.
The speed warning system has one or two* warn­
ing thresholds that function independently of
each other and that have somewhat different
purposes:
Speed warning 1
You can use speed warning 1 to set the maximum
speed while you are driving. This setting will re­
main in effect until you turn off the ignition, as­
suming that you have not changed or reset the
setting .
The. (USA models) /. (Canada models)
speed wa rning symbol in the warning 1 display
appears when you exceed the maximum speed .
It
goes out when the speed falls below the stored
maximum speed.
The speed warning symbol will also go out if the
speed
exceeds the stored maximum speed by
more than about 2S mph
(40 km/h) for at least
10 seconds. The stored maximum speed is delet­
ed.
Setting speed warning 1 c:>
page 88.
Speed warning 2*
Storing warning 2 is recommended if you always
want to be reminded of a certain speed, for ex­
ample when you are traveling in a country that
has a general maximum speed limit, or if you do
not want to exceed a specified speed for winter
tires.
The. (USA models) /. (Canada models)
speed warning 2 symbol appears in the display
when you exceed the stored speed limit. Unlike
warning 1, it will not go out until the vehicle
speed drops below the stored speed limit.
Setting speed warning 2
c:>page 88.
(D Tips
Even though your vehicle is equipped with a
speed warning system, you should still watch
the speedometer to make sure you are not
driving faster than the speed limit.

A WARNING
- Always pay attention to the traffic around
you when the cruise control is in operation .
You are always respons ible for your speed
and the distance between your veh icle and
other veh icles .
-

-For reasons of safety, cruise control should
not be used in the city, in stop-and-go traf­
fic, on twisting roads and when road condi­
t ions are poor (such as ice, fog, gravel,
heavy ra in and hydroplan ing) -risk of acci­
dent .
- Turn
off the cruise control temporar ily when
enter ing turn lanes, h ighway exit lanes o r in
construction zones.
- Please note that inadvertently "rest ing"
your foot on the accelerator pedal causes
the cruise control not to brake. This is be­
cause the cruise cont rol is overridden by the
dr iver's acceleration.
- If a brake system ma lf u nction such as over­
heating occu rs when the c ruise contro l sys­
tem is switched on, the braking function in
the system may be switched
off . The other
cruise contro l functions remain active as
long as the indicator light
[lj;(i )~i~ (US mod­
els)/ .. (Canadian models) is on .
(D Tips
-Vehicles with manual transmission: You can
attain the set speed only if the gear that is
currently engaged will allow it, or if it does
not tax the engine and allows it to run
smooth ly. Therefore sh ift into a higher or
lower gear in a timely ma nner.
- The brake lights illuminate as soon as the
brakes apply automatically .
