2009 MERCEDES-BENZ GL SUV Owners Manual

It is better to have the vehicle transported
than to have it towed.
When towing, observe the legal requirements
in all countries concerned.
! When towing, pull away slowly and
smoothly. If the tractive power is too high,
the vehicles could be damaged.
! Do not use the towing eye for recovery,
as this could damage the vehicle. If in
doubt, recover the vehicle with a crane.
! You may tow the vehicle for a maximum
of 50 km. A towing speed of 50 km/h must
not be exceeded.
For towing distances over 50 km, the entire
vehicle must be lifted up and transported.
! On vehicles with KEYLESS GO*, use the
key instead of the Start/Stop button. Turn
the key to position 2in the ignition lock and
shift the automatic transmission to N. Then
turn the key back to 0and leave it in the
ignition lock.
! Only secure the tow cable or towing bar
to the towing eyes. You could otherwise
damage the vehicle.
R Tow-starting the vehicle is not permitted.
R The vehicle may not be towed with the front
or rear axle raised.
R If the vehicle has suffered transmission
damage, have it carried away on a trans-
porter or trailer.
R If the engine does not start, try jump-start-
ing it (Y page 276).
R If it is not possible to jump-start the vehicle,
have it towed to the nearest qualified spe-
cialist workshop, e.g. a Mercedes-Benz
Service Centre.
R If you are towing the vehicle, move the
automatic transmission selector lever to N
and turn the key to position
2 (Y page 63) in the ignition lock.
R Before towing the vehicle, make sure that
the battery is connected and charged. Oth-
erwise:
- you cannot switch on the ignition.
- you cannot shift the transmission to posi-
tion N.
- you have no support when braking.
i Switch off the automatic locking feature
before the vehicle is towed (Y page 107).
Otherwise, you could be locked out when
pushing or towing the vehicle.
Deactivate tow-away protection*
(Y page 55) before the vehicle is towed. Fitting the towing eye
Vehicles with a trailer tow hitch*: if you
intend to use the vehicle for towing, fit the ball
coupling and connect the towbar to this.
Opening the covers The mountings for the removable towing eyes
are located in the bumpers. They are located
at the front and rear behind covers. 278

used to pull the vehicle onto a trailer or trans-
porter if you wish to transport it.
! Only secure the vehicle by the wheels or
wheel rims, not by parts of the vehicle such
as axle or steering components. Otherwise,
the vehicle could be damaged. Recovering a vehicle that has become
stuck
Take great care when recovering a vehicle
whose drive wheels have become embedded
in loose earth or mud, particularly if the vehi-
cle is laden.
When recovering the vehicle do not use jerky
movements and do not pull it at an angle. The
chassis could otherwise be damaged.
Never attempt to recover a vehicle with a
trailer attached.
Pull out the vehicle backwards, if possible
using the tracks it made when it became
stuck. Towing and tow-starting

Towing in the event of malfunctions
In the event of damage to the transfer
case Have the propeller shafts between the axles
and the transfer case removed.
Have the vehicle towed with the front axle
raised.
In the event of damage to the front axle
Have the propeller shaft between the rear
axle and the transfer case removed.
Have the vehicle towed with the front axle
raised.
In the event of damage to the rear axle Have the propeller shaft between the front
axle and the transfer case removed.

In the event of damage to the electrical
system If the battery is defective, the automatic
transmission will be locked in position P. To
shift the automatic transmission to neutral,
you must supply power to the vehicle’s elec-
trical system in the same way as jump-start-
ing (Y page 276).
Have the vehicle transported on a transporter
or trailer. Fuses
Notes on changing fuses
The fuses in your vehicle serve to close down
faulty circuits. If a fuse blows, all the compo- nents on the circuit and their functions will
fail.
Blown fuses must be replaced with fuses of
the same rating, which you can recognise by
the colour and value. The fuse ratings are lis-
ted in the fuse allocation chart. A Mercedes-
Benz Service Centre will be happy to advise
you. G
Risk of fire
Only use fuses that have been approved for
Mercedes-Benz vehicles and which have the
required fuse rating for the systems con-
cerned. Do not attempt to repair or bridge
faulty fuses. A circuit overload could other-
wise cause a fire. Have the cause traced and
rectified at a qualified specialist workshop,
e.g. a Mercedes-Benz Service Centre.
If the newly inserted fuse also blows, have the
cause traced and rectified at a qualified spe-
cialist workshop, e.g. a Mercedes-Benz
Service Centre.
! Only use fuses that have been approved
for Mercedes-Benz vehicles and which
have the correct fuse rating for the system
concerned. Otherwise, components or sys-
tems could be damaged.
The fuses are located in various fuse boxes:
R dashboard fuse box on the front-passenger
side
R fuse box in the engine compartment on the
right-hand side of the vehicle
R fuse box in the luggage compartment on
the right-hand side of the vehicle
Fuse allocation chart The fuse allocation chart is located with the
vehicle tool kit (Y
page 209) in the stowage
compartment under the luggage compart-
ment floor. 280

Notes on the technical data
i The technical data was determined in
accordance with EU directives. All data
applies to the vehicle's standard equip-
ment. Therefore, the data may differ for
vehicles with optional equipment. You can
obtain further information from a
Mercedes-Benz Service Centre.
You can find technical data on the Internet at:
www.mercedes-benz.com Genuine Mercedes-Benz parts
Mercedes-Benz tests genuine parts and con-
version parts and accessories which have
been specifically approved for your vehicle for
their reliability, safety and suitability. Despite
ongoing market research, Mercedes-Benz is
unable to evaluate other parts. Therefore,
Mercedes-Benz accepts no responsibility for
the use of such parts in Mercedes-Benz vehi-
cles, even if they have been independently or
officially approved.
In Germany and some other countries, certain
parts are only officially approved for installa-
tion or modification if they comply with legal
requirements. All genuine Mercedes-Benz
parts meet this requirement. The use of non-
approved parts may invalidate the vehicle's
general operating permit. This is the case if:
R they cause a change of the vehicle type
from that for which the vehicle's general
operating permit was granted.
R other road users could be endangered.
R the emission or noise levels are adversely
affected.
The use of non-approved parts could affect
your vehicle's operating safety. Therefore,
Mercedes-Benz recommends genuine
Mercedes-Benz parts and conversion parts
and accessories that have been approved for
your vehicle. H
Environmental note
Daimler also supplies reconditioned assem-
blies and parts which are of the same quality
as new parts. For these, the same warranty
applies as for new parts.
Genuine Mercedes-Benz parts and approved
conversion parts and accessories are availa-
ble from Mercedes-Benz Service Centres.
There, you can also receive advice about tech-
nical modifications and have the parts pro-
fessionally fitted.
Always specify the vehicle identification num-
ber and engine number when ordering genu-
ine Mercedes-Benz parts. You will find these
numbers on your vehicle's identification
plates, for example (Y page 286). Vehicle electronics
Tampering with the engine electron-
ics
G
Risk of accident
Only have work on the engine electronics and
related components carried out at a qualified
specialist workshop which has the necessary
specialist knowledge and tools to carry out
the work required. Mercedes-Benz recom-
mends that you use a Mercedes-Benz Service
Centre for this purpose. In particular, work
relevant to safety or on safety-related sys-
tems must be carried out at a qualified spe-
cialist workshop. Otherwise, the vehicle’s
roadworthiness could be affected.
! Only have maintenance work on the
engine electronics and its associated parts,
such as control units, sensors and connec-
tor leads, performed at a qualified special-
ist workshop, e.g. a Mercedes-Benz Service
Centre. Otherwise, vehicle components
may wear more quickly and your vehicle's
warranty and operating permit may be inva-
lidated. 284

Retrofitting of two-way radios and
mobile phones (RF transmitter)
Use the Technical Specification
ISO/TS 21609 36
implementation regulation
when retrofitting RF (radio frequency) trans-
mitters.
If your vehicle has fittings for two-way radio
equipment (e.g. taxis, hire cars or official vehi-
cles), use the power supply or aerial connec-
tions intended for use with the basic wiring.
Be sure to observe the manufacturer's addi-
tional instructions when installing the fittings.
! Damage resulting from installation work
that has not been carried out correctly is
not covered by the Mercedes-Benz implied
warranty.
To ensure correct installation, Mercedes-
Benz recommends having this work done
at a Mercedes-Benz Service Centre or at a
qualified specialist workshop.
Transmission output Transmission output at the aerial base must
not exceed the maximum values below. Waveband Maximum trans-
mission output

The following aerial positions may be used if
RF transmitters have been properly installed:
Aerial positions
:
Front roof area (vehicles with sliding/tilt-
ing sunroof*: observe the roof's sweep)
; Rear mudguard (recommended installa-
tion position: on the side which faces the
centre of the road) G
Risk of accident
Incorrect retrofitting of RF transmitters can
cause the vehicle electronics to malfunction,
impair the vehicle's operating safety and,
thus, also impair your own safety.
To ensure correct installation, Mercedes-
Benz recommends having this work done at a
Mercedes-Benz Service Centre or at a quali-
fied specialist workshop. G
Risk of injury
Improper installation of RF transmitters can
lead to increased electromagnetic radiation in
the vehicle interior. Using an exterior aerial
takes into account current scientific discus-
sions relating to the possible health hazards
that may result from electromagnetic fields.
To ensure correct installation, Mercedes-
Benz recommends having this work done at a
Mercedes-Benz Service Centre or at a quali-
fied specialist workshop.
