Vehicle jackThe vehicle jack is located underneath the
cargo compartment floor.
Storage position
Remove vehicle jack from its storage
compartment (
page 470).
Turn crank handle in the direction of ar-
row as far as it will go.

Vehicles with factory-mounted
running-boards*:
Your vehicle is equipped with a scissors-type
jack (located under the cargo compartment
floor) designed for use with factory-mounted
running boards. Only use this jack when jacking
up vehicles with factory-mounted running boards
as otherwise the vehicle’s underbody can be
damaged. See separate instructions for scis-
sors-type jack.
!
To prevent damage, always disengage the
strap of the securing hook and lower the cargo
compartment floor (
page 469) before closing
the tailgate.
Warning!
G
The jack is designed exclusively for jacking
up the vehicle at the jack take-up brackets
built into both sides of the vehicle. To help
avoid personal injury, use the jack only to lift
the vehicle during a wheel change. Never
get beneath the vehicle while it is supported
by the jack. Keep hands and feet away from
the area under the lifted vehicle. Always
firmly set parking brake and block wheels
before raising vehicle with jack.
Do not disengage the parking brake while
the vehicle is raised. Be certain that the jack
is always vertical (plumb line) when in use,
especially on hills. Always try to use the jack
on a level surface.
Make sure that the jack arm is fully seated
in the jack take-up bracket. Always lower
the vehicle onto jackstands of sufficient
capacity before working under the vehicle.

Resetting activated head restraints
Resetting activated head restraints
If the active head restraints have been trig-
gered in a rear-end collision, the active
head restraints must be reset. Otherwise,
the active head restraints cannot offer any
additional protection in the event of anoth-
er rear-end collision.
You can tell that the head restraints have
been activated when they have been
moved forward and cannot be adjusted.
1Reset tool
2Active head restraint
Take the reset tool1 out of the
Mercedes-Benz vehicle literature
pouch.
Guide reset tool1 into the rectangu-
lar opening of the active head
restraint2.
Press reset tool1 downward in direc-
tion of arrow until you hear the head re-
straint release mechanism audibly
disengage.
Pull out reset tool1.
Firmly press the active head restraint
cushion backward towards the head re-
straint cover in direction of arrow until
it engages.
Repeat this procedure on the active
head restraint for the second front
seat.
After resetting the active head
restraints store the reset tool1 in the
Mercedes-Benz vehicle literature
pouch.
For information on active head restraints,
see “Active head restraint” (
page 80).
For information on head restraint adjust-
ment, see “Seats” (
page 43).

For your convenience, we recommend that
you have this work carried out by an authorized
Mercedes-Benz Light Truck Center.
You will find the reset tool for manually operating
the active head restraints in the Mercedes-Benz
vehicle literature pouch.Warning!
G
For safety reasons, have the active head re-
straints checked by an authorized
Mercedes-Benz Light Truck Center after a
rear-end collision.
Warning!
G
When pushing back the head restraint cush-
ion, take care that your fingers do not be-
come caught between the head restraint
cushion and the cover. Failing to do so may
lead to injury.!
Be careful not to damage upholstery.

Vehicles with collapsible tire:
You can use the power outlet in the cargo com-
partment or in the front of the rear seats to oper-
ate the electric air pump even when the ignition
is switched off, e.g. in order to inflate the col-
lapsible emergency spare tire.
An emergency shut-off feature ensures that the
vehicle’s electrical voltage does not fall below a
minimum level. If the voltage drops to this mini-
mum level, the power outlets are automatically
switched off. This ensures that enough power re-
mains to start the engine.

Battery
Battery
The battery is located under the front
passenger seat.
The battery should always be sufficiently
charged in order to achieve its rated ser-
vice life.
If you use your vehicle mostly for
short-distance trips, you will need to have
the battery charge checked more
frequently.
When replacing the battery, always use
batteries approved by Mercedes-Benz.
If you do not intend to operate your vehicle
for an extended period of time, consult an
authorized Mercedes-Benz Light Truck
Center about steps you need to observe.Batteries contain materials that can harm
the environment if disposed of improperly.
Recycling of batteries is the preferred
method of disposal. Many states require
sellers of batteries to accept old batteries
for recycling.i
Mercedes-Benz recommends to have the
battery replaced at an authorized
Mercedes-Benz Light Truck Center.
