Loading
The handling characteristics of a fully load-
ed vehicle depend greatly on the load dis-
tribution. It is therefore recommended to
load the vehicle according to the illustra-
tions shown, with the heaviest items being
placed towards the front of the vehicle.
Always place items being carried
against front or rear seat backrests,
and fasten them as securely as possi-
ble.
The heaviest portion of the cargo
should always be kept as low as possi-
ble against front or rear seat backrest
since it influences the handling charac-
teristics of the vehicle.
For additional safety when transporting
cargo while the rear seats are unoccu-
pied, fasten the outer seat belts cross-
wise into the opposite side buckles.
Always pad off sharp edges.
Warning!
G
Always fasten items being carried as secure-
ly as possible using cargo tie-down rings and
fastening materials appropriate for the
weight and size of the load.
In an accident, during hard braking or sud-
den maneuvers, loose items will be thrown
around inside the vehicle, and can cause in-
jury to vehicle occupants unless the items
are securely fastened in the vehicle.
To help avoid personal injury during a colli-
sion or sudden maneuver, always use parti-
tion net when transporting cargo.
Never ride vehicle with the tailgate open.
Deadly carbon monoxide (CO) gases may
enter vehicle interior resulting in uncon-
sciousness and death.
iThe rear cargo compartment is the pre-
ferred place to carry objects. The en-
larged cargo compartment (rear seats
folded) should only be used for items
which do not fit in the rear cargo com-
partment alone.

tentionally (e.g. SmartKey inside vehicle),
and the reserve key is not handy:
Contact the Mercedes-Benz Response
Center at 1-800-756-9018 (in the USA)
or 1-888-923-8367 (in Canada).
You will be asked to provide your pass-
word which you provided when you
completed the subscriber agreement.
Then return to your vehicle and press
the tailgate lock for minimum of
20 seconds until the SOS button is

sent to you shortly after the completion of
your acquaintance call.The Response Center will then unlock your
vehicle with the remote door unlocking
feature.Stolen vehicle tracking services

Report the incident to the police.
The police will issue a numbered inci-
dent report.
Pass this number on to the
Mercedes-Benz Response Center along
with your password issued to you when
you subscribed to the service.
The Response Center will then attempt
to covertly contact the vehicle’s
Tele Aid system. Once the vehicle is lo-
cated, the Response Center will con-
tact the local law enforcement and you.
The vehicle’s location will only be pro-
vided to law enforcement.
iThe remote door unlock feature is avail-
able if the relevant cellular phone net-

215 Operation
Driving instructions
Checklist before off-road driving
Engine oil level
Check the engine oil level
(page 229). The display
ENGINE OIL
LEVEL - OK
must appear in the multi-
function display.
Only then can the vehicle obtain a trou-
ble-free oil supply, even on steep gradi-
ents.
Tires
Check the tread depth and maintain
specified tire pressure (see tire pres-
sure label inside the fuel filler flap).
Check tires for possible damage and
remove foreign objects.
Replace missing valve caps.
iWhenever driving in off-road mode, we
recommend:
Keeping doors, tailgate, windows
and sliding/pop-up roof closed.
Switching cruise control off.
!Observe the following during off-road
driving:
Adjust vehicle speed to condition of
terrain. The more uneven, rutty and
steeper the terrain, the lower the
speed should be. Drive through wa-
ter slowly at an even speed, avoid-
ing a bow wave.
Be especially careful when driving
in unknown territory. It may be nec-
essary to get out of the vehicle and
scout the path you intend to take.
Watch out for obstacles, such as
rocks, holes, tree stumps and ruts.
Avoid excessive engine
speeds – drive at moderate engine
speeds (max. 3000 rpm).
Before driving through water, deter-
mine its depth.
Do not stop vehicle while immersed
in water, and do not shut off the en-
gine.
In sandy soil, drive at a steady
speed as allowed by conditions.
This helps overcome the vehicle
rolling resistance and reduces the
likelihood of the vehicle sinking into
the ground.
Do not initiate jumps with the vehi-
cle. It interrupts the forward mo-
mentum of the vehicle.
Always drive on slopes with the en-
gine running and the vehicle in
gear.
Inspect the vehicle for possible
damage after each off-road trip.
