Seats and storage
General recommen­
dations
Why is your seat adjustment so
important?
The safety belts and the airbag system can
only provide maximum protection if the front
seats are correctly adjusted.
There are various ways of adjust ing the front
seats to provide safe and comfortable support
for the driver and the front passenger . Adjust
you r seat prope rly so that :
- you can easily and quick ly reach all the
switches and controls in the instrument
panel
-your body is prope rly supported thus reduc­
ing physical stress and fatigue
- the safety be lts and a irbag system can offer
maximum protection
¢ page 151 .
In the following sec tions, you will see exactly
how you can best adjust you r seats .
There are special regulations and instructions
for insta lling a child seat on the front pas­
senger's seat. Always fo llow the information
regarding ch ild safety provided in
q page 17 4, Child Safety.
A WARNING
Incorrect seating position of the driver and
all other passengers can result in serious
personal in jury.
- Always keep your feet on the floor when
the vehicle is in motion -never p ut your
f eet on top of the instrument panel, out
of the w indow or on top of the seat cush­
ion . Th is app lies especially to the passen­
gers .
If your seating position is incorrect,
yo u increase the r isk of injury in the case
of sudden braking or an acc ident.
If the
a irbag infla tes and the seating positio n
is incorrect, this could result in personal
injury o r even death.
- It is import ant for bo th the driver and
front passenger to keep a distance of at least 10 inches (25 cm) between them­
selves and the steering wheel and/or in­
strument panel. If you're s itting any
closer than th is, the a irbag system can­
not protect you properly . In addition, the
front seats and head restraints must be
adjusted to your body height so that they
can give you max imum protect ion.
- Always try to keep as much distance as
possible between yourself and the steer­
ing wheel o r inst rument pane l.
- Do not adjust the driver's o r front pas­
senger's seat whi le the vehicle is moving.
Your sea t may move unexpected ly, caus­
ing sudden loss of vehicle cont rol and
personal injury . If yo u adjust yo ur seat
while the veh icle is moving, yo u are out
of posit ion.
Driver's seat '
The correct seat position is important for safe
and relaxed driving.
We recommend tha t you adjus t the dr iver's
seat in the fo llowing manner :
.,. Adjust t he seat in fore and aft direction so
t ha t you can eas ily push the peda ls to the
floor w hile keeping your knees sl igh tly bent
q A in Why is your seat adjustment so im­
portant? on page 58.
.. Adjust the backrest so that when you sit
w ith your back against t he backrest, you can
still grasp the top of the steering wheel.
.. Adjust the head restraint so the upper edge
is as even as poss ible with the top of your
head . If that is not poss ible , try to adjust
t he head restraint so that it is as close to
t his pos it ion as possib le
q page 65.
A WARNING
Neve r place any objects in the dr iver's foot ­
well. An object could get into the pedal
a rea and interfere with pedal function . In
case of sudden braking or an acc ident, you
would not be able to brake or accelerate .

Starting off with a trailer
To prevent rolling back unintentionally on an
incline, do the following:
11-Keep the switch© pulled and depress the
accelerator. The parking brake stays applied
and prevents the vehicle from rolling back­
ward .
11-You can release the switch<®> once you are
su re that you a re develop ing enough for­
ward momentum at the wheels as you de­
press the accelerator.
D epending on the weight of the r ig (vehicle
and tra ile r) and the severi ty of the incl ine, you
may roll backwards as you start. Yo u can pre­
vent rolling backwards by holding the parking brake switch<®) p ulled out and acce lerating -
just as you would when starting on a hill with
a conventional hand brake.
Emergency braking
In the event that the conventional brake sys­
tem fails or locks.
11-In an emergency, pull the switch(®) and
contin ue to p ull it to slow your vehicle down
with the parking brake.
11-As soon as you release the switch (®) or ac-
ce lerate, the braking process stops.
If you pull the switch<®> and hold it above a
speed of about 5 mph (8 km/h), the emergen­
cy braking function is initiated. The vehicle is
braked at all four wheels by activating the hy­
draulic brake system. Th e brake performance
i s similar to making an emergency stop
~ &..
In order not to activate the emergency brak­
ing by m istake, an audible warning tone (buz­
ze r) sou nds when the switch C®> is pulled. As
soon as the switch(®) is released, or the accel­
e rator pedal is dep ressed, emergency b ra ki ng
stops.
_& WARNING
Emergency braking should only be used i n
an emergency, when the normal foot brake
has failed or the brake pedal is obstructed .
On the ro ad 87
Using the parking b rake to pe rform emer­
gency brak ing 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 i ts associated compo­
nents (ABS, ASR, EDL). In corners and
when road o r weathe r cond itions are bad,
a full brake appl ication can ca use the vehi­
cle to sk id or the re ar end to break away -
risking an acciden t.
Start-Stop-System
' Description
Applies to vehicles: wit h Start -Stop-System
The Start-Stop-System can help increase fuel
economy and reduce CO2 emissions .
In the Start-Stop-mode, the engine shuts off
automat ica lly w hen the vehicle is stopped,
such as at a traffic light. The ignition remains
switched on du ring this stop phase. The en­
gine wi ll be automat ica lly restarted when
needed.
The last Start-Stop-System sett ing (on/off us­
ing the button
I O\l ~I) will be restored when the
i gnition is turned on. The L ED in the
1(7() .. 1 but­
ton turns on when the Star t-Stop-System is
swi tched off man ually.
Basic requirements for the Start -Stop
mode
- The d rive r's doo r is closed.
- The d river ' seat belt is latched .
- The hood is closed .
- The vehicle must have been driven faster
than
2.5 mph (4 km/h) since the last stop.
- A trailer is not hitched to the vehicle.
_& WARNING
-Never let the vehicle roll with the eng ine
sw itched off. You cou ld lose control over
the vehicle. Th is can lead to a collision
and serio us in ju ries.
- The brake booster and the steering sup­ port do not work while the engine is
