lutely necessary .

When stopping at a traffic signal or stopp ing in
city traffic on vehicles with 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 parking brak e eliminates the tendency
to creep with a drive range engaged . As soon as
you dr ive off as usual , the parking brake is re­
leased automatically and the veh icle starts to
move.
Starting on sl opes
When starting on inclines, the start ing ass ist pre­
vents the vehicle from unintentionally rolling back. The braking force of the parking brake is
not released until sufficient driv ing force has
been b uilt up at the whee ls .
@ Tips
For safety reasons, the park ing brake is re­
leased automatically only when the dr iver's
safety belt is engaged in the buckle.
Emergency braking
In the event that the conventional brake system
fails or locks.
.,. In an emergency, pull the switch @c::, page 75 ,
fig. 79
and continue to pull it to slow your vehi­
cle down with the park ing brake.
.,. As soon as you release t he sw itch @ or acceler-
ate, the braking process stops.
I f you pull the sw itch @and ho ld it above a
speed of about
5 mph (8 k m/ h), the emergen cy
b rak ing func tion is initia ted . The vehicle is braked
at all four wheels by activa ting the hydrau lic
b rake system. The brake pe rformance is s imilar
to making an emergency stop
c::, A .
In o rder no t to activate the emergency bra king by
mista ke, an audible warning tone (b uzzer)
sounds when the sw itch @ is pulled. As soon as
the switch @ is released, or t he accelerator peda l
is depressed, emergency braking stops.

failed or the bra ke peda l is obstructed. Us ing
the parking brake to perform emergency brak­ i ng 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 assoc iated components (ABS, ASR,
E DS). In corners and when road o r weather
conditions are bad, a f ull bra ke applica tion
can cause the ve hicl e to skid o r th e rear end to
break away -risking an ac cident.
Speed warning system
Overview
The speed warning system helps you to keep your
driving speed below a set speed limit.
T he speed warning system warns if the driver ex ­
ceeds a previous ly stored maximum speed . A
warning tone will sound as soon as the veh icle
speed exceeds the set speed by about 3 mph
(3 km/h) . At the same t ime, a warning symbol
appears in the display . The symbol's appearance
mig ht be different in some models .
The speed warn ing system has two warning
t hr esholds that funct ion independent ly of each
othe r and t hat have somewhat d ifferent pu rpos­
es:
Speed wa rning 1
You can use speed warning 1 to set the maximum
speed wh ile you are driving. Th is sett ing will re­
main in effect until you turn off the ign ition, as ­
suming that you have not changed or reset th e
setting.
The . (USA models)/ . (Canada models)
speed warning symbo l in the warn ing 1 disp lay
appears when you exceed the maximum speed .
It
goes out when the spe ed falls be low the stored
ma ximum speed.
The speed warn ing symbol will also go out if the
speed
exceeds the stored maximum speed by
more than about
25 mph (40 km/h) for at least
10 seco nds. The stored maxim um speed is dele t-
ed.

Storing cargo correctly
Loading the luggage compartment
All luggage and other objects must be properly
stowed and secured in the luggage compart ­
ment.
Fig . 120 Safe load position ing: place heavy objects as low
and as far forwa rd as poss ible.
"' N .,. ~ ,,: CX) ID
Loose items in the luggage compartment can
shift suddenly, changing vehicle handling charac­
teristics. Loose items can also increase the risk of
serious personal injury in a sudden veh icle ma­
neuver or in a coll is ion.
,.. Distribute the load evenly in the luggage com­
partment.
,.. Always place and p roperly secure heavy items in
the luggage compartment as low and as far for ­
ward as possible
¢ fig . 120.
,.. Secure the load with the cargo net* or with
non-elastic straps secured to the tie-downs
Qpage 64.
,.. Make sure that the rear seatback is securely
latched in place.
A WARNING
Improperly stored luggage or other items can
fly through the veh icle causing serious per­
sonal injury in the event of ha rd braking or an
accident. To help reduce the r isk of serious
personal injury:
- Always put objects, for examp le, luggage or
other heavy items in the luggage compart­
ment.
- Always secure objects in the luggage com­
partment us ing the tie-down eye lets and
suitable straps.
Dri vin g s afe ty
A WARNING
-Heavy loads wi ll influence the way your vehi-
cle handles . To help reduce the risk of a loss
of control leading to serious personal injury:
- Always keep in mind when transporting
heavy objects, that a change in the center of
grav ity can also cause changes in vehicle
handling:
- Always distribute the load as evenly as
possible .
- Place heavy objects as far forward in the
luggage compartment as possib le .
- Never exceed the Gross Axle We ight Rating
or the Gross Vehicle Weight Rating specified
on the safety compliance s ticker on the left
door jamb. Exceeding permissib le weight
standards can cause the vehicle to slide and
handle differently .
- Please observe information on safe dr iving
¢page 111 .
A WARNING
-To help prevent poisonous exhaust gas from
being drawn into the vehicle, always keep the
rear lid closed wh ile driving.
- Never transport objects la rger than those
fitting completely into the luggage area be­
cause the rear lid cannot be fully closed .
- If you absolutely must dr ive with the rear lid
open, observe the following notes to reduce
the risk of poisoning:
- Close all windows,
- Close the s unroof,
- Open all a ir outlets in the ins trumen t pan-
el,
- Switch off the air recirculat ion,
- Set the fresh air fan to the highest speed.
A WARNING
-A lways make sure that the doors , all windows,
the sunroof and the rear lid are securely
closed and locked to reduce the risk of injury
when the vehicle is not being used.
- After closing the rear lid, always make sure that it is properly closed and locked.

Why use safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for peo­
ple riding in vehicles .
Fig. 122 Unbelted occupants in a ve hicle heading for a wall
Fig . 123 The vehicle cras hes into th e wall
CD
~ ± The physical principles are simple. Both the vehi­
cle and the passengers possess energy which var­ ies with vehicle speed and body weight . Engi­
neers call this energy "kinetic energy."
The higher the speed of the vehicle and the
greater the vehicle's weight, the more energy
that has to be "absorbed" in the crash.
Vehicle speed is the most significant factor. If the
speed doubles from 15 to 30 mph (25 to 50 km/
h) , the energy increases 4 times!
Because the passengers of this vehicle are not us­
ing safety belts~
fig. 122, they will keep moving
at the same speed the vehicle was moving just
before the crash, until something stops them -
here, the wall
~fig. 123 .
The same principles apply to people sitting in a
vehicle that is involved in a frontal collision. Even
at city speeds of 20 to 30 mph (30 to 50 km/h),
the forces acting on the body can reach one ton
Safety belts
(2,000 lbs. or 1,000 kg) or more . At greater
speeds, these forces are even higher .
People who do not use safety belts are also not
attached to their vehicle. In a frontal collision
they will also keep moving forward at the speed
their vehicle was travelling just before the crash.
Of course, the laws of physics don't just apply to
frontal collisions, they determ ine what happens
in all kinds of accidents and collisions.
What happens to occupants not wearing
safety belts?
In crashes unbelted occupants cannot stop themselves from flying forward and being in­
jured or killed . Always wear your safety belts!
Fig. 124 A driver not wea ring a safe ty belt is violen tly
thrown forwa rd
Fig. 125 A rear passenger not wear ing a safety belt w ill
fly
fo rward and strike t he dr ive r
Unbelted occupants are not able to resist the tre­
mendous forces of impact by holding tight or
bracing themselves . Without the benefit of safe­
ty restraint systems, the unrestrained occupant
will slam v iolently into the steering wheel, in­
strument panel, w indshield, or whatever else is
i n the way~
fig. 124 . This impact with the veh i­
cle inter ior has all the energy they had just before
the crash. .,.
