2009 MERCEDES-BENZ GL SUV ignition

G
Risk of accident
If EBV is malfunctioning, the brake system is
still available with full brake boosting effect.
However, the rear wheels can still lock, e.g.
under full braking. This could cause you to
lose control of your vehicle and cause an acci-
dent. You should therefore adapt your driving
style to the different handling characteristics. 4ETS (Electronic Traction System)
4ETS makes it possible to pull away or accel-
erate on a slippery surface. It brakes the
wheels individually if they start to spin.
The d warning lamp in the instrument
cluster lights up briefly when the engine is
started. This indicates that the warning lamp
is operational.
X Activate the LOW RANGE off-road gear
(Y page 114) if appropriate to driving con-
ditions.
The d warning lamp in the instrument
cluster flashes at any speed if at least one tyre
has exceeded its tyre grip limit. G
Risk of accident
If the d warning lamp in the instrument
cluster flashes, proceed as follows:
R only depress the accelerator pedal as far as
necessary when pulling away.
R accelerate less when driving.
R adapt your driving style to suit the prevail-
ing road and weather conditions.
Otherwise, the vehicle could skid.
If you drive too fast, 4ETS cannot reduce the
risk of an accident. 4ETS cannot override the
laws of physics.
! Only operate the vehicle briefly (for a max-
imum of ten seconds) on a brake dyna-
mometer. Turn the key in the ignition lock
to position 0or 1. You could otherwise
damage the drive train or the brake system. !
A function or performance test should
only be carried out on a twin-axle dyna-
mometer. If you wish to operate the vehicle
on such a dynamometer, please consult a
Mercedes-Benz Service Centre in advance.
You could otherwise damage the drive train
or the brake system.
i If the brakes are subjected to heavy loads,
4ETS switches off automatically for a brief
period so that the brakes do not heat up
further. If, for this reason, 4ETS does not
engage, the dwarning lamp in the
instrument cluster lights up. The message
ABS, ESP unavailable see Owner's
Manual also appears in the multi-function
display.
! The engine must be off when the parking
brake is being checked on the brake dyna-
mometer. Application of the brakes via
4ETS may otherwise destroy the braking
system.
Off-road terrain-4ETS (Electronic Trac-
tion System) A 4ETS system specifically suited to off-road
terrain is activated automatically if the LOW
RANGE* off-road gear is selected
(Y page 114). Distance warning function* (vehicles
with Distronic*)
This function will issue a warning at speeds of
around 30 km/h or more if:
R for a period of several seconds, the dis-
tance to the vehicle in front is too short for
the speed at which you are travelling. The
· distance warning lamp in the instru-
ment cluster will light up.
R you are approaching the vehicle in front too
rapidly. An intermittent warning tone will
then sound and the ·distance warning
lamp will light up in the instrument cluster. Driving safety systems

In order to maintain the appropriate distance
to the vehicle in front and thus prevent a
crash, you must apply the brakes yourself. G
Risk of accident

tions if the distance warning lamp ·in the
instrument cluster lights up or an intermittent
warning tone sounds.
If necessary, brake or manoeuvre to avoid an
obstacle.
X To activate/deactivate: activate or deac-
tivate the distance warning function in the

out when the vehicle is being pushed or
tested on a dynamometer. Tailgate
Points to remember
G
Risk of poisoning
Exhaust fumes could enter the vehicle interior
if the engine is running and the tailgate is
open. This could poison you. Therefore, you
should make sure that the tailgate is always
closed when the engine is running.
! The tailgate swings up and to the rear
when opened. Therefore, make sure that
there is sufficient clearance above and
behind the tailgate.
Do not leave the key in the luggage compart-
ment. Otherwise, you could lock yourself out.
On vehicles with a spare wheel bracket*, you
can only open the tailgate after first opening
the spare wheel bracket* completely.
i You will find details of the tailgate opening
dimensions in the Technical data section
(Y page 295). The tailgate can be:
R
opened and closed manually
(Y page 61)
R opened and closed* automatically from
outside (Y page 62)
R opened and closed* automatically from
inside (Y page 62) Spare wheel bracket*
G
Risk of accident
While the spare wheel bracket is folded to the
side, the tail lamps may be blocked from view.
Other road users may then fail to see you and
crash into your vehicle. Additionally, secure
your vehicle using a warning lamp or a warn-
ing triangle.
Do not drive with the spare wheel bracket fol-
ded out.
Make sure that the spare wheel bracket is
closed correctly.
Otherwise, the freely moving spare wheel
bracket could injure people or cause an acci-
dent.
! Do not wash vehicles equipped with a
spare wheel bracket in an automatic car
wash.

Points to remember
For information about folding the rear bench
seat forwards, see the "Luggage compart-
ment enlargement" section (Y page 154). G
Risk of injury
The seats can still be adjusted when there is
no key in the ignition lock. For this reason,
children should never be left unsupervised in
the vehicle. They could become trapped when
adjusting a seat. 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 injury
Make sure that nobody can become trapped
when you adjust the seat.
Observe the notes concerning the airbag sys-
tem. 64
