2009 MERCEDES-BENZ GL SUV engine

Speedometer with segments
The segments in the speedometer indicate
which speed range is available.
Distronic* mode:
One or two segments around the stored
speed light up. Rev counter
The red band in the rev counter indicates the
engine's overrevving range. The fuel supply is
interrupted to protect the engine when the
red band is reached.
! Do not drive in the overrevving range.
Doing so will damage the engine. Outside temperature display
G
Risk of accident
At temperatures just above freezing point, the
road could be icy, particularly in wooded areas
or on bridges. The vehicle could start skidding
if you fail to adapt your driving style. You
should therefore always adapt your driving
style and speed to suit the weather condi-
tions.
Changes in the outside temperature are dis-
played after a short delay. On-board computer
Points to remember
The on-board computer is activated as soon
as you turn the key to position 1in the ignition
lock. G
Risk of accident
Only use the on-board computer when road
and traffic conditions permit. You would oth-
erwise be distracted and unable to concen-
trate properly on driving, and could cause an
accident. Multi-function steering wheel
You can control the multi-function display and
the settings in the on-board computer using
the buttons on the multi-function steering
wheel. :

Deactivating
X
Press button :.
Indicator lamp ;goes out.
The DSR symbol appears in the multi-func-
tion display with the Offmessage.
DSR switches off automatically if you drive
faster than 35 km/h. The DSR symbol
appears in the multi-function display with the
Off message. You also hear a warning tone.
Changing the set speed while the vehi-
cle is in motion When DSR is activated, you can change the
set speed to a value between 4 km/h and
18 km/h while the vehicle is in motion. X
To increase or reduce the set speed by
1 km/h increments: briefly press the
cruise control lever to the pressure point,
up : for a higher set speed or down ;for
a lower set speed.
The set value appears in the multi-function
display.
X To increase or reduce the set speed in
10 km/h increments: briefly press cruise
control beyond the pressure point, up :
for a higher set speed or down ;for a
lower set speed.
The set value appears in the multi-function
display. LOW RANGE off-road gear
The LOW RANGE off-road gear assists you in
driving off-road and when fording. When LOW
RANGE is engaged, the engine’s performance
characteristics and the gearshifting charac-
teristics of the automatic transmission are
adapted for this purpose. ABS, ESP ®
and
4ETS programs especially adapted to off-road
driving are also activated. You will find infor-
mation about driving off-road in the "Opera-
tion" section (Y page 188). You will find infor-
mation about driving safety systems in con-
junction with LOW RANGE in the "Safety" sec-
tion (Y page 49).
Shift ranges HIGH RANGE
Road position for all nor-
mal driving situations
LOW RANGE
Off-road position for driv-
ing off-road and fording
The gear ratio between the
engine and wheels is only
approximately one third of
that in the HIGH RANGE
road position. The drive
torque is correspondingly
higher as a result.
Do not use LOW RANGE:
R on slippery road surfa-
ces, e.g. in the case of
slush
R on snow or ice-covered
roads
R if you have snow chains
on your vehicle G
Risk of accident
Always wait for the gear change process from
HIGH RANGE to LOW RANGE – and from LOW
RANGE to HIGH RANGE – to complete. Do not
turn off the engine while changing gear and 114

do not switch the automatic transmission to
another gear.
If you do not wait for the gear change process
to complete, it may not be correctly imple-
mented. The transfer case may then be in
neutral and the connection between the
engine and the drive axles may be disen-
gaged. The vehicle could then move freely,
even if a gear is engaged, and could inadver-
tently start moving, particularly if it is on a
slope.
Observe the messages in the multi-function
display.

An acoustic warning will also sound. The
gear change process has not been comple-
ted. LOW RANGE is in the neutral position.
There is no connection between the engine
and the drive wheels.
! Do not drive any further, otherwise you
could damage the vehicle's drive train.
XStop the vehicle. Take into account the
road and traffic conditions when doing
this.
X Depress the parking brake.
X Carry out the gear change process

Differential locks improve the vehicle’s trac-
tion.
Your vehicle is equipped with the following:
R A differential lock for the transfer box: this
controls the balance between the front and
rear axles.
R A differential lock for the rear axle: this
controls the balance between the wheels
and the rear axle.
4ETS (Y page 53) controls the compensation
between the wheels and the front axle.
Engaging the differential locks Automatic mode
Use automatic mode
;for all driving situa-
tions, including driving off-road or when ford-
ing.
In automatic mode, the differential locks are
engaged and disengaged according to driving
requirements. This guarantees sufficient trac-
tion for most driving situations with unrestric-
ted vehicle steerability.
X Start the engine.
The differential locks are in automatic
mode. The indicator lamp in selector
wheel :lights up above symbol for auto-
matic mode ;.
Engaging manually G
Risk of accident
When driving on a firm road surface, only drive
in automatic mode, never with manually
engaged differential locks. If differential locks
have been engaged manually, the vehicle's
steerability is greatly impaired and the risk of
an accident thereby increased.
Do not manually engage or disengage the dif-
ferential locks while cornering. The vehicle
motion could otherwise be jerky. You could
lose control of the vehicle as a result and
cause an accident.
Only engage the differential locks manually if
traction in automatic mode is insufficient.
At speeds of up to 30 km/h, you can engage
the differential locks by hand.
X Start the engine.
X Turn selector wheel :to desired position
= or?.
The indicator lamp in selector wheel :
lights up at the corresponding symbol. 116
