96 Belt warning for driver and front
passenger
The < seat belt warning lamp in the instru-
ment cluster reminds you that all occupants
should fasten their seat belts. The <seat
belt warning lamp may light up continuously
or it may flash. Additionally, there may be a
warning tone.
The < seat belt warning lamp goes out and
the warning tone ceases when the driver and
the front passenger have fastened their seat
belt.
For certain countries only: regardless of
whether the driver or the front passenger is
already secured, the <seat belt warning
lamp lights up for six seconds after the engine
has been started. The <seat belt warning
lamp then goes out if both the driver and the
front passenger have fastened their seat belt.
i Further information about the <seat
belt warning lamp (Y page 281). Belt height adjustment
You can adjust the seat belt height on the
driver&#39;s seat and front-passenger seat.

Risk of accident
Only adjust the steering wheel when the
vehicle is stationary and do not pull away
until the steering wheel adjustment mech-
anism is locked in position. You might oth-
erwise drive without the steering wheel
adjustment mechanism being locked in
position. As a result you could be distracted
from road and traffic conditions by an unex-
pected movement of the steering wheel
and thereby cause an accident.
The steerability of the vehicle is however
not affected.
X Check whether seat 3and the head
restraint are adjusted properly
(Y page 77).
Make sure that:
R you are as far away from the driver&#39;s front
airbag as possible
R you are sitting in a normal upright posi-
tion
R you can fasten the seat belt properly R
you have moved the backrest to an
almost vertical position
R you have set the seat angle so that your
thighs are gently supported
R you can depress the pedals properly
R you have adjusted the head restraint so
that the back of your head is supported
at eye level by the central area of the
head restraint
X Check whether steering wheel 1is adjus-
ted properly (Y page 88).
Make sure that:
R you can hold the steering wheel with your
arms slightly bent
R you can move your legs freely
R you can see all the displays in the instru-
ment cluster clearly
X Check whether you have fastened seat belt
2 properly (Y page 94).
It should:
R fit snugly across your body
R be routed across the middle of your
shoulder
R routed in your pelvic area across the hip

Light switch
For safety reasons, Mercedes-Benz recom-
mends that you drive with the lights switched
on even during the daytime. In some coun-
tries, daytime operation of headlamps varies
due to legal and voluntary requirements. In
these countries, the dipped-beam headlamps
are automatically switched on when the
engine is started.
i If you drive in countries in which traffic
drives on the opposite side of the road to
the country where the vehicle is registered,
oncoming traffic may be dazzled by the
asymmetrical dipped-beam headlamps.
Have the headlamps changed to symmet-
rical dipped beam when driving in these
countries. You can obtain information
about this from any Mercedes-Benz Service
Centre. Controls

Risk of accident
Do not keep any objects in the driver&#39;s foot-
well. If you use a floormat or carpet in the
driver&#39;s footwell, make sure that they are
correctly secured and that there is suffi-
cient clearance for the pedals.
Objects could otherwise get between the
pedals in the event of sudden braking or
acceleration. You may then no longer be
able to brake, change gear or accelerate as
intended. This may result in an accident and
injury. G
Risk of poisoning
Never leave the engine running in enclosed
spaces. The exhaust gases contain carbon
monoxide. Inhaling exhaust fumes consti-
tutes a health hazard and could lead to loss
of consciousness or even death.
! Do not depress the accelerator pedal
when starting the engine. i
If you depress the brake when starting the
engine, pedal travel will be unusually long
and there will be less pedal resistance.

catalytic converter to reach its operating
temperature more quickly. Hill start assist
Hill start assist helps you when pulling away
on uphill gradients of more than 5°. G
Risk of accident
Hill start assist is not a parking brake. It
does not prevent the vehicle from rolling
away.
When parking, always depress the parking
brake and set the automatic transmission
to P. X
To pull away on an uphill slope, release the
brake and depress the accelerator pedal.
The hill start assist continues to hold the
braking pressure for up to one second. This
allows you to pull away evenly without the
vehicle rolling back.
i The brake pedal remains in the depressed
position until the hill start assist releases
the braking pressure.
Hill start assist will not function if:
R you are pulling away on a downhill gradient
R the automatic transmission is in neutral N

Risk of accident
Only remove the key from the ignition lock
when the vehicle is stationary as you can-
not steer the vehicle with the key removed.
Never leave children unsupervised in the
vehicle. They could release the parking
brake. This could lead to a serious or fatal
accident. G
Risk of fire
Make sure that the exhaust system does
not under any circumstances come into
contact with easily ignitable material such
as dry grass or petrol. The material could
otherwise ignite and set the vehicle on fire.

self and others.

Notes on the transmission
G
Risk of accident
The movement of the pedals must not be
impaired in any way. Do not keep any
objects in the driver&#39;s footwell. Make sure
that floormats or carpets are correctly
secured and that there is sufficient clear-
ance for the pedals. G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This
could cause the drive wheels to lose their
grip and the vehicle could skid. This could
cause you to lose control of your vehicle
and cause an accident. Controls
