72 Seats and stor age
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 adjusting 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 quickly reach all the
switches and controls in the instrument
panel
-your body is properly supported thus reduc­
ing physical stress and fatigue
- the safety be lts and airbag system can offer
maximum protection
¢ page 183 .
In the following sections, you will see exactly
how you can best adjust your seats .
There are special regulations and instructions
for installing a child safety seat on the front
passenger's seat. Always follow the informa­
tion regarding child safety provided in
¢ page 204, Child Safety.
A WARNING
Incorrect seating position of the driver and
all other passengers can result in serious
personal injury.
- Always keep your feet on the floor when
the vehicle is in motion -never put your
feet on top of the instrument panel, out
of the window or on top of the seat cush­
ion . This applies especially to the passen­
gers .
If your seating position is incorrect,
you increase the risk of injury in the case
of sudden braking or an accident.
If the
airbag inflates and the seating position
is incorrect, this could result in personal
injury or even death.
- It is important for both 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 sitting any
closer than this, the airbag 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 maximum protection.
- Always try to keep as much distance as
possible between yourself and the steer­
ing wheel or instrument panel.
- Do not adjust the driver's or front pas­
senger's seat while the vehicle is moving.
Your seat may move unexpectedly, caus­
ing sudden loss of vehicle control and
personal injury. If you adjust your seat
while the vehicle is moving, you are out
of position.
Driver's seat '
The correct seat position is important for safe
and relaxed driving.
We recommend that you adjust the driver's
seat in the following manner :
.,. Adjust the seat in fore and aft direction so
that you can easily push the peda ls to the
floor wh ile keeping your knees slightly bent
i::::> A in Why is your seat adjustment so im­
portant? on page 72.
.. Adjust the seatback so that when you sit
with your back against the seatback, you can
still grasp the top of the steering wheel.
.. Adjust the head restraint so the upper edge
is as even as possible with the top of your
head . If that is not poss ible , try to adjust
the head restraint so that it is as close to
this position as possible
c:::> page 77.
A WARNING
Never place any objects in the driver's foot­
well. An object could get into the pedal
area and interfere with pedal function. In
case of sudden braking or an accident, you
would not be able to brake or accelerate .

.,. When the indicator l ight
I.I sw itches off,
turn the ignition key to pos it ion @ but do
not press the accelerator pedal.
.,. Re lease the ignition key once the engine
sta rts. The starter must not continue run­
ning.
A cold engine may sound loud after it has
been started . This is due to the hydraulic
va lves building up oil pressure. This is normal
and is not a need for concern.
If the engine does not start immediately, stop
trying after 10 seconds and then try to restart
the engine about 30 seconds Later.
Glow plug system*
Diesel engines are equipped with a glow plug
system whose preheating t ime is controlled by the coo
lant and outs ide temperature . Start
the engine
immediately after the glow plug
indicator light
m sw itches off.
The glow plug indicator light will only illumi­
nate for approximate ly 1 second when the en­
gine is warm or the outside temperature is
higher than 46 °F (8 °C). That means you can
start the engine
immediately .
A WARNING
-Never start or let the engine run in a con-
fined or enclosed area. Exhaust fumes
from the engine contain carbon monoxide,
a colorless and odorless gas . Carbon mon­
oxide can be fatal if inhaled.
- Never leave the engine idling unattend­
ed. An unattended veh icle w ith a runn ing
engine poses a danger of personal injury
or theft .
(D Note
- Avo id high engine speeds, fast accelera­
tion or heavy engine loads while the en­ gine is still cold. This could damage the
eng ine .
- Th e engine cannot be started by pushing
or towing the vehicle .
@ For the sake of the environment
To avoid unnecessary engine wear and to
reduce exhaust emissions, do not let your
vehicle stand and warm up. Be ready to
drive
off immediately after starting your
vehicle. Maintain moderate speed until the
engine is completely warm . Remember,
the engine performs best at operating
temperature.
· Stopping the engine
.,. Turn the ignition key to posit ion @
~page 106, fig . 120 .
A WARNING
-
-Never turn off the engine until the vehi-
cle 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.
S ince you cannot steer and stop normal­
ly, this can lead to accidents and ser ious
injuries.
- The rad iator fan can continue to run for
up to 10 min utes even after you have
turned off the engine and removed the ign ition key. The radiator fan can also
turn on again if the engine coolant heats
up because of intense sunlight or heat
build -up in the engine compartment.
«I) Note
Do not stop the engine immed iate ly after
hard or extended dr iving. Keep the engine
running for approximately two minutes to
prevent excessive heat build-up .

The parking brake warning light. (USA)/ .
(CON) illuminates when the parking brake is
set and you switch on the ignition.
A WARNING
-
Always release the parking brake com­
pletely. A partially engaged brake will
overheat the rear brakes, reduce their ef­
fectiveness and cause excessive wear. This could lead to brake failure and an accident .
(D Note
Only after the vehicle has come to com­
plete stop, should you firmly set the park­
ing brake and
move the selector lever into
P.

• Move the selector lever to P.
.. Turn the engine off~_& .
.. When on inclines or declines, turn the steer­
ing wheel so that the vehicle will roll into
the curb if it begins to
move.
A WARNING
This is how you can reduce the risk of in­
jury 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 pas­
senger compartment in the event of an
emergency. Danger to life!
- Never leave children unsupervised in the
vehicle. Children could release the park­
ing 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 tem­
perature in a parked vehicle can reach
dangerous levels.
Q) Note
- Please exercise care when you park your
vehicle in parking areas with parking bar­
riers 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 oc­
cur, you may wish to stop short of having
the front tires of your car touch the park­
ing barrier or curb.
- Please also exercise exceptional care
when you drive up or down steep ramps
or drive
over curbs or other obstacles, for
which the vehicle is not designed, be­
cause components of th@ vehicle close to
the ground, such as bumper covers,
spoilers and suspension and exhaust sys­
tem components, may become dam­
aged.
Starting on hills
Hill Hold makes it easier to start on hills.
The system is activated when the brake pedal
is depressed
for a few seconds . For this, the
vehicle must be standing in uphill driving di­ rection.
After releasing the brake pedal, the brake power is held for a
brief moment to prevent
the vehicle from rolling back when starting. At
this time, you can easily begin to
move your
vehicle.
A WARNING
- If you did not begin moving immediately
after releasing the brake pedal, under
certain circumstances, the vehicle would
begin to roll backward. Depress the ..,.

brake pedal immediately or engage the
parking brake.
- Should the engine stall, depress the
brake pedal immediately or engage the
parking brake.
- In order to prevent the vehicle from roll­
ing back unintentionally when starting in
stop-and-go traffic, keep the brake pedal
depressed for a few seconds before driv­
ing off .
- When you leave the vehicle - even if only
briefly -, sw itch off the ignition and
make sure to remove the ignition key . Al­
so engage the
park ing br ake to prevent
your vehicle from rolling u nintentionally.
Th is parti cularly applies if chi ldren are

the type of display in your vehicle.
A WARNING
- Always pay attention to traffic even when
the cruise control is switched on. You are
always responsible for your speed and
the distance between your veh icle and
other veh icles .
- For safety reasons, the cruise control
should not be used in the city, in stop­
and-go traffic, on twisting roads and
when road conditions are poor (such as
ice, fog , gravel, heavy rain and hydro­
p laning) - risk of accident.
- Turn off the cruise control temporarily
when en ter ing turn lanes, highway exit
lanes or in construction zones .
- Please note that inadvertently "resting"
your foot on the accelerator pedal causes
the cruise control not to brake. This is because the cruise control is overridden
by the driver's acceleration.
- Never use the cruise control when driving
off-road o r on unpaved roads. The cruise
control is intended for use only when the
vehicle is being operated on paved roads,
and is not suitable for use off-road or on
unpaved roads .
(D Tips
The cruise control cannot maintain a con­
stant speed when driving downhill. The ve­
hicle will accelerate under its own weight .
Downshift to a lower gear or use the
brakes to slow down.
