flashers on or off.
When the emergency flasher is on, all four turn signals blink at the same time. The turn signal indicator lights¢¢ in the instrument
cluster, as well as the light in the emergency flasher switch~ blink
likewise.
The emergency flashers will turn on automatica lly if you are in an
accident where the airbag has deployed.
[ i ] Tip s
You should turn on the emergency flashers when:
• you are the last vehicle standing in a traffic jam so that any other
vehicles coming can see you, or when
• your vehicle has broken down or you are in an emergency situa ­
tion, or when
• your vehicle is being towed by a tow truck or if you are towing
another vehicle behind you. •

Your vehicle is equipped w ith an electromechanical parking brake
which replaces the handbrake . The parking brake is designed to
prevent the vehicle from rolling unintentionally .
In addition to the norma l functions of a trad itiona l hand brake, the
e lectromechanical parking brake provides various convenience and
safety functions.
Em erg en cy brake
An emergency brake ensures that the vehicle can be slowed even if
the
normal brakes fa il=> page 136, "Emergency braking".
Indi ca to r light s
• If the pa rking brake is app lied with the ignition turned on, the
indicator light in the instrument cluster (U.S. models:~-Canadian
models: ©) and in the switch © will come on .
• If the parking brake is applied with the ignition
turned off , the
indicator light in the instrument cluster (U .S . models :~~ , Canadian
models :(®) ) and in the switch(®) will come on for about 30 seconds
and then go out.
& WARNING
If the vehicle i s stationary and the transmis sio n i s e ngag ed with
the eng ine running , th e engine should n ot b e speeded up (e .g .
manu ally from under the ho od). Oth erw ise th e vehi cle will start t o
mo ve • you r un the ris k of an acc ident .
0 Note
If the warning/indicator light (U .S . models: BRAKE , Canadian models:
{(j))) flashes in the instrument cluster, there is a brake system
malfunction . By pressing the
I C HE CK] button , you can bring up a
driver message which explains the malfunction in more detail. If the
message
Parking brake ! Plea se conta ct w ork shop appears, there is
a parking brake malfunction which you should have repaired imme ­
diate ly by an authorized dealership=:>
page 30.
[ i ] Tips
• You can app ly the parking brake at any time -even with the igni ­
tion turned off . T he ignition mus t be turned on in order to release
the parking brake.
• Occasional noises when the parking brake is applied and
released are norma l and are not a cause for concern .
• The parking brake goes through a se lf -test cycle at regular inter ­
va ls - when the vehicle is parked. Any associated no ises are
normal. •

• .___O_ n_ t_h _e _ r_o _a_ d __________________________________________________ _
Starting off with a trailer
T o prevent rolling back unintentionally on an incline, do
the following:
- Keep the switch pulled and depress the accelerator. The
parking brake stays applied and preve nts the vehicle
f rom rolling backward .
- You can release the switch o nce you are sure t hat you are
deve lop ing enough forward momentum at the whee ls as
you depress 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 rol ling backwards by holding the parki ng brake sw itch
pul led out and acce lerating -just as you would when starting on a
h ill with a conventional hand brake. •
Emergency braking
In the event that the conventi on al b rake system fails or
locks.
- Pull th e swi tch and continu e to pull it to slow you r veh icle
with t he par king brake in an emergency .
- As soon as you r elease the switch or acc elerate, the
braking pro cess s tops .
If you pull the swi tch and hold it above a speed of about 5 mph (8
km/h), the emergency braking function is initiated . T he vehicle is
braked at all fou r whee ls by activating the hydraulic brake system .
Brake performance is similar to making an emergency stop~&.
So that emergency braking is not activated by mistake, an audib le
warning tone (buzzer) sounds when the switch is pulled . As soon as the switch is released, or the accelerator pedal is depressed, emer­
gency b raking stops .
& WARNING
Emergency braking should only be u sed in an emergen cy, when
the normal foot br ake has f ailed or the br ake ped al i s obstructed .
U sing the parking brake to perform emergen cy brakin g will slow
yo ur vehicle a s if yo u had made a full brake app lication . The law s
of phy sic s cannot be su spe nded even with E SP and it s asso ciated
c ompon ents ( AB S, ASR, EDS ). In corner s and whe n ro ad or
w eather conditions are bad , a full brak e application can cau se the
vehi cle to skid or the r ear end to break a way -ri sking an
ac cident .•

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. 151 Front
bumper: Position of
radar sensor
Adaptive Cruise Control can help make driving more relaxed and
less tiring, particularly during long trips on interstates or other
highways that are generally straight .
Set ACC to maintain a constant, legal travel speed between 20 and
95 mph (30 -150 km/h) that is appropriate for prevailing traffic
conditions. Select a following distance to the vehicle ahead and ACC
will adjust your speed to maintain that distance .
Adaptive Cruise Contro l has technical limitations that you must
know, so please read this section carefully, understand how the
system works and use it proper ly at all times .
How does it work?
You can operate the Adaptive Cruise Control using the lever on the
steering wheel column =>
page 142, "How is the speed stored?" and
=>
page 144, "How is the distance set?" .
Contro 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 146, "Driver information" .
What is important for you to know
There are limits to what Adaptive Cruise Control can do as the
vehicle is being driven =>
page 150, "System limitations" .
& WARNING
Improper use of the Adaptive Cruise Control can cause collisions,
other accidents and serious personal injury.
• Always remember that the Adaptive Cruise Control has limits -
it will not slow the vehicle down or maintain the set distance
when you drive towards an obstacle or something 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 .
• Never drive at speeds that are too fast for traffic, road and
weather conditions .
• The Adaptive Cruise Control cannot slow or 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 30% of the vehicle 's maximum braking ability.
Always be prepared to brake and take evasive action to avoid colli­
sions and other accident situations.
• Never allow the closing speed between you and other vehicles
to be so high that the Adaptive Cruise Control may not be able to _,,,

- Push the s lider switch

the d istance by one step.
The distance at which Adaptive Cruise Contro l fo llows a vehicle in
front is determined by
time intervals. A time int erval to a v ehicl e in
front is estab lished and maintained . This produces a speed -depen ­
dent interval. The higher the speed, the greater the saf ety interval in
feet (meters).
For example, if the interval
DI STA NCE 3 is set , a vehicle in front is
followed at a
time interval of 1.8 seconds .
Fo r a speed o f
50 mph (80 km /h ) this would be equivalent to a
distance of
1 3 1 feet (40 meters ) to the ve hicle in fron t.
The distances given here are nominal values . The vehicle speed may
exceed or fall short of these target speeds, depending on the
driving situation and the driving sty le of the v ehicle ahead.
