2009 MERCEDES-BENZ GL SUV airbag

Correct driver's seat position
G
Risk of accident
Only adjust the driver's seat when the vehicle
is stationary. You will otherwise be distracted
from the road and traffic conditions and you
could lose control of the vehicle as a result of
the seat moving. This could cause an acci-
dent. G
Risk of accident
Only adjust the steering wheel when the vehi-
cle is stationary and do not pull away until the
steering wheel adjustment mechanism is
locked in position. Otherwise, you might drive
without the steering wheel adjustment mech-
anism being locked in position and be distrac-
ted from road and traffic conditions by an
unexpected movement of the steering wheel
and cause an accident.
However, the steerability of the vehicle is not
affected.
X Check whether seat =and the head
restraint are adjusted properly
(Y page 64). Make sure that:
R
you are as far away from the driver'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 :is adjus-
ted properly (Y page 70).
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 ;properly (Y page 75).
It should:
R fit snugly across your body.
R be routed across the middle of your
shoulder.
R be routed in your pelvic area across the
hip joints. Lights

Intelligent Light System* (bi-xenon
headlamps*) The Intelligent Light System is a system which
adjusts the headlamps automatically to suit
the prevailing driving and weather conditions.
The bi-xenon headlamps offer enhanced func-
tions to improve illumination of the road sur-
face, e.g. depending on the vehicle speed or
weather conditions. The system includes the
active light function, motorway mode and
extended range foglamps. The system is only
active when it is dark.
You can activate or deactivate the "Intelligent
Light System" using the on-board computer
(Y page 106). Active light function The active light function is a system that
moves the headlamps according to the steer-
ing movements of the front wheels. In this
way, relevant areas remain illuminated while
driving. This allows you to recognise pedes-
trians, cyclists and animals.
Motorway mode
Motorway mode increases the range of the
beam.
Active:
R
If you are driving at speeds above
110 km/ha nd do not make any large steer-
ing movements for 1000 m.
R If you are driving at speeds above
130 km/h.
Motorway mode remains active unless your
speed drops speeds below 80 km/h.
Not active: if you are driving at speeds below
80 km/h. 82

Cleaning the steering wheel boss and
dashboard G
Risk of injury
When cleaning the steering wheel boss and
dashboard, do not use cockpit sprays or
cleaning agents containing solvents. Cleaning
agents containing solvents cause the surface
to become porous, and as a result plastic
parts may break away and be thrown around
the interior when an airbag is deployed which
may result in severe injuries.
X Wipe the dashboard and steering wheel
boss with a damp, lint-free cloth (e.g. a
microfibre cloth) and cleaning agent.
X Heavy soiling: use car care and cleaning
products recommended and approved by
Mercedes-Benz.
Cleaning the COMAND display X
Before cleaning the display, make sure that
it is switched off and has cooled down.
X Clean the display surface using a commer-
cially-available microfibre cloth and TFT/
LCD display cleaner.
X Dry the display surface using a dry micro-
fibre cloth.
! For cleaning, do not use any of the fol-
lowing:
R alcohol-based solvents or petrol
R abrasive cleaning agents
R commercially-available household clean-
ing agents
These may damage the display surface. Do
not exert pressure when cleaning the dis-
play surface as this may lead to irreversible
damage.
Cleaning the seat covers !
Do not use microfibre cloths to clean gen-
uine leather, artificial leather or 204
