& WARNING
• Never turn off the engine until the vehicle has come to a
complete stop.
• The brake booster and servotronic only work when the engine
is running. With the ignition turned off, you have to apply more
force when steering or braking. Since you cannot steer and stop
normally, this can lead to accidents 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.
• After the engine has been switched off, the radiator fan can
continue to run for up to 10 minutes -even with the ignition
switched off. It can also switch on again after some time if the
coolant temperature rises as the result of a heat buildup or if the
engine is hot and the engine compartment is additionally heated
by the sun's rays.
0 Note
If the engine has been under heavy load for an extended period,
heat builds up in the engine compartment after the engine is
switched off -there is a risk of damaging the engine. Allow the
engine to run at idle for about 2 minutes before switching it off. •

[ i] Tips
• You can apply the parking brake at any time - even with the igni­
tion turned off. The ignition must be turned on in order to release
the parking brake .
• Occasional noises when the parking brake is applied and
released are normal and are not a cause for concern .
• The parking brake goes through a self -test cycle at regular inter ­
vals - when the vehicle is parked . Any associated noises are
normal. •
Parking
To prevent a parked vehicle from rolling away, there are a
few things you should do.
When you park your vehicle, do the following
- Stop the vehicle using the brake pedal.
- Pull the switch to apply the electromechanical parking
brake.
- Move the selector lever into the
P position ~& .
- Switch off the engine and remove the ignition key from
the ignition lock.
When you park your vehicle on hills, do the
following - Stop the vehicle using the brake pedal.
- Pull the switch to apply the electromechanical parking
brake.
- If you are parking headed downhill, turn the front wheels
toward the curb. - If you are
parking headed uphill, turn the front wheels
awayfrom the curb.
- Move the selector lever into the P position .
- Switch off the engine and remove the ignition key from
the ignition lock.
& WARNING
This is how you can reduce the risk of injury when leaving your
vehicle.
• Never park the vehicle where it can come in contact with dry
grass, spilled fuel or any other flammable materials.
• When parking on hills, always turn the wheels so that the front
wheels will first roll into the curb, if the vehicle should start to roll.
• Never allow anyone -especially small children -to remain in the
vehicle when it is locked. Locked doors make it more difficult for
rescuers to access the passenger compartment in the event of an
emergency. Danger to life!
• Never leave children unsupervised in the vehicle. Children
could release the parking brake or move the gearshift lever out of
gear. The vehicle could start to roll away and cause an accident.
• No matter what the season is, the temperature in a parked
vehicle can reach dangerous levels.
0 Note
• Please exercise care when you park your vehicle in parking areas
with parking barriers or curbs. Parking barriers and curbs vary in height and could damage your bumper and related components as
the front of your vehicle moves over a barrier or curb that is too
high, as you park or as you back out of a parking spot. In order to be
sure that no such damage can occur, you may wish to stop short of
having the front tires of your car touch the parking barrier or curb . ..,_

On the road -
----------------
• Please also exercise exceptional care when you drive up or down
steep ramps or drive over curbs or other obstac les, f or which the
vehicle is not designed, because components of the veh ic le close to
the g round, suc h as bumper covers, spoi lers and suspension and
exhaust system components, may become damaged . •
Starting off with a trailer
To p reven t ro lling b ack unintentionally o n an incline, do
the foll owing:
- Keep the sw it c h pulled and depr ess the acce lera to r. The
p arking b rake stays a pplie d a nd pre ve nts the v ehi cle
f rom rolling backw ard .
- You can rele ase the switch o nce you are sure t hat you are
deve lo p ing e noug h forward mo mentum at the whee ls as
yo u de press the accelera tor.
Depending on the weight of the rig (vehicle a nd trailer) and the
severity of the inc line, you may roll backwards as you start. You can
prevent rolling bac kwards by holding the parking brake switch
pul led out and acce lerating -just as you would when starting on a
hill with a conven tiona l hand brake .•
Emergency braking
In the event that the conventional brake system fails or
locks .
-Pull the sw itch and cont inue to pu ll it to slow yo ur vehicle
with the parking b rake in an emergency.
- As soo n as you release the sw itch or acce le rat e, the
b raking proc ess s tops .
Controls and equip ­
ment
I f you pull the switch and hold it above a speed of about 5 mph (8
km/h), the emergency braking function is initia ted . The ve hic le is
braked at all four whee ls by activating the hydraulic brake system.
Brake performance is sim ilar to mak ing an eme rgency stop=>& .
So that emergency braking is not activated by mistake, an audible
warning tone (buzzer) sounds when the switch is pulled. As soon as
t he sw itch is released, or the accelera tor pedal is depressed, emer ­
gency braking stops.
& WARNING
Emergency braking should only be used in an emergency , when
the normal foot brake ha s failed or the brake pedal i s obstructed .
Using the parking brake to perform emergency braking will slow
your vehicle as if you had made a full brake application. The law s
of physi cs cannot be suspended even with E SP and its asso ciated
components (ABS , ASR , EDS ). In corner s and when road or
we ather conditions are bad , a full bra ke appl ication can cau se the
vehicle to skid or the rear end to break away -risking an
accident .•
Driver messages in the instrument cluster
Caution : Vehicle p arked too steep
This message appears when the park ing brake is app lied on an
inc line that exceeds about 30% .
I n this case the braking power of the parking brake may

Adaptive Cruise Control
Speed and distance control system
Applies to vehic les : with Adaptive C ruise Cont rol
Description
The Adaptive Cruise Control driver assistance program is
a combined speed and distance control system.
Fig. 129 Front
bumper: Position of
radar sensor
Any speed between about 20 mph (30 km/h) and about 95 mph
(150 km/h) can be set and he ld with the Adaptive Cruise Con trol. The
system also regulates a pre-set distance from the vehicle ahead
within the limits of the system described.
Driving can be more relaxed, particularly on long trips on interstates
or on other highways that are generally straight.
How does it work?
You can operate the Adaptive Cruise Control using the lever on the
steering wheel column::::> page 137, "How is the speed stored?" and
=> page 140, "How is the distance (time interval) set?".
Con tro ls and eq uip­
ment
Driver information
Important information is brought up in the speedometer and in the
instrument cluster display as the vehicle is being driven
=> page 142, "Driver information" .
What is important for you to know
The Adaptive Cruise Control is set with system -specified limits, that
is, as a driver, you will have to adjust the speed and distance to the
vehic le ahead in some instances=> page 146, "Driver intervention
prompt" and=> page 147, "System limita tions".
& WARNING
Improper use of the Adaptive Cruise Control can cause collisions,
other accidents and serious personal injury .
• Never drive at speeds that are too high for traffic , road and
weather conditions.
• Never follow the vehicle in front so closely that you cannot stop
your vehicle safely. The Adaptive Cruise Control cannot brake the
vehicle safely when you follow another vehicle too closely. Always
remember that the Adaptive Cruise Control has a braking power
that is only about 25% of the vehicle's maximum braking ability,
the automatic braking function cannot bring the vehicle to a stop.
• Never use Adaptive Cruise Control on roads where you cannot
drive safely at a steady speed, including city, stop-and-go or heavy
traffic, on winding roads or when road conditions are poor (for
example, on ice, gravel , in fog , heavy rain or on wet roads that
increase the risk of hydroplaning).
• The radar sensor's
vision can be reduced by rain, snow and
heavy spray. This can result in vehicles driving ahead being inade ­
quately detected or, in some circumstances, not detected at all. If
necessary , take action yourself! ._
Vehicle care I I irechnical data

• .___A_ d_ a_ p =- t_iv _ e _ C_ r_u _is_ e_ C _ o_ n_ t _r _o_ l --------------------------------------------
& WARNING (continued)
• Always turn off Adaptive Cruise Control when entering turn
lanes, highway exit lanes and construction zones or similar situa ­
tions because the vehicle will automatically accelerate to the
stored speed.
• Never rest your foot on the accelerator pedal, especially when
the Adaptive Cruise Control is being used because doing so will
override the braking function and prevent the brakes from being
applied by the system when it detects a situation when the brakes
must be applied.
• Always remember that the Adaptive Cruise Control has limits -
it does not react when you drive towards an obstacle or some­
thing else on or near the road that is not moving, such as vehicles stopped in a traffic jam, a stalled or disabled vehicle .
• Always remember that the Adaptive Cruise Control cannot
detect a vehicle that is driving towards you in your traffic lane and
that it cannot detect narrow vehicles such as motorcycles and
bicycles .
[ i) Tips
• For safety reasons, the stored speed is deleted when the ignition
is turned off.
• The Electronic Stabilization Program (ESP) and the Anti -Slip
Regulation (ASRl cannot be deactivated when the Adaptive Cruise
Control is switched on. If the ESP and the Anti -Slip Regulation (ASRl
has been deactivated and you then switch on the Adaptive Cruise
Control, the ESP function will also be activated automatically.
• Damage caused by accidents (e.g. if the vehicle is damaged
when parking) can affect the radar sensor settings. This can cause
the system to malfunction or switch off completely.
• The radar sensor cover is heated. In winter conditions, you
should still check before driving to make sure it is free of ice and
snow. If necessary, clean the area near the radar sensor carefully
=>
page 135, fig. 129. • To
ensure that the radar sensor is not blocked, foreign objects
(e.g. stickers, larger license plate mounts, add -on parts) must not
cover the area near the radar sensor=>
page 135, fig. 129. The area
near the radar sensor must not be painted, either. •
Applies to veh ic les: with Adaptive Cruis e Contro l
How does Adaptive Cruise Control work?
Vehicles traveling ahead are detected with the aid of a
radar sensor.
Fig. 130 Radar sensor
measurement range
A radar sensor is built into the front of the vehicle=> fig. 130. The
system is intended to measure the distance to reflective surfaces. If
a measurement is not possible, the system does not respond.
Open road
When the road is clear, the Adaptive Cruise Control works like cruise
control. It maintains a constant target speed specified by the driver.
Driving in traffic
If a vehicle driving ahead is detected, the Adaptive Cruise Control
decelerates (within the limits of the system)=>
page 146, "Driver
intervention prompt" and=>
page 147, "System limitations" to its
speed and after adjusting, tries to maintain the set distance from
the vehicle ahead. The vehicle may temporarily drive slower than
the set speed while adjusting=>
