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.

..... N
0 ::..:: co ..... ..... A WARNING
Improperly stored luggage or other items can
fly through the vehicle causing serious per­
sonal injury in the event of hard braking or an
accident . To help reduce the risk of serious
personal injury:
- Always put objects, for example, luggage or
other heavy items in the luggage compart­
ment.
- Always secure objects in the luggage com­
partment using the tie-down eyelets and
suitable straps.
A WARNING
Heavy loads will 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
gravity 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 possible.
- Never exceed the Gross Axle Weight Rating
or the Gross Vehicle Weight Rating specified
on the safety compliance sticker on the left
door jamb. Exceed ing permissible weight
standards can cause the veh icle to slide and
hand le differently.
- Please observe information on safe driving
qpage 121.
A WARNING
To help prevent poisonous exhaust gas from
being drawn into the vehicle, always keep the
rear lid closed while driving.
- Never transport objects larger than those
fitting completely into the luggage area be­
cause the rear lid cannot be fully closed.
- If you absolutely must drive with the rear lid
open, observe the fo llowing notes to reduce
the risk of poisoning:
- Close all windows,
- Close the sunroof,
Driving safety
-Open all air outlets in the instrument pan­
el,
- Switch off the air recirculation
,
- Set the fresh air fan to the highest speed .
A WARNING
=
Always make sure that the doors, a ll win-
dows, the sunroof and the rear lid are secure­
ly closed and locked to reduce the risk of in­
jury when the vehicle is not being used.
- After closing the rear lid, always make sure
that it is properly closed and locked .
- Never leave your vehicle unattended espe­
cially with the rear lid left open . A child
could crawl into the vehicle through the lug­
gage compartment and close the rear lid be­
coming trapped and unable to get out . Be­
ing trapped in a vehicle can lead to ser ious
personal injury.
- Never let children play in or around the vehi­ cle .
- Never let passengers ride in the luggage
compartment . Vehicle occupants must al­
ways be properly restrained in one of the ve­
h icle 's seat ing positions.
(D Tips
-Air circulation helps to reduce window fog­
ging . Stale air escapes to the outs ide
through vents in the tr im panel. Be sure to
keep these slots free and open.
- The tire pressure must correspond to the
load. The t ire pressure is shown on the tire
pressure label. The tir e pressure label is lo­
cated on the driver's side B-pillar . The tire
pressure label lists the recommended cold
tire inflation pressures for the vehicle at its
maximum capacity weight and the tires that
were on your vehicle at the time it was man­
ufactured. For recommended tire pressures
for normal load conditions, please see chap­
ter

Why use safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for peo­
ple riding in vehicles .
Fig. 142 Unbelted occupants in a vehicle heading for a wall
Fig . 143 The vehicle crashes into the 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.
Veh icle 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. 142, they will keep mov ing
at the same speed the vehicle was moving just
before the crash, until something stops them -
here, the wall
¢fig. 143.
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. o r 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 determine 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. 144 A driver not wearing a safety belt is v iolently
thrown forward
Fig. 145 A rear passenger not wearing a safety belt will f ly
forwa rd and strike the
driver
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 viol ently into the steering wheel, in­
strument panel, windshield, or whatever else is
in the way
¢fi g. 144. This impact with the vehi­
cle interior has all the energy they had just be-
fore the crash.
