Vehicle tool kit
General notes
The vehicle tool kit can be found in the
stowage well under the cargo compartment
floor.
iApart from certain country-specific
variations, the vehicles are not equipped
with a tire-change tool kit. Some tools for
changing a wheel are specific to the
vehicle. For more information on which
tools are required to perform a wheel
change on your vehicle, consult a qualified
specialist workshop.
Tools required for changing a wheel may
include, for example:
RJack
RWheel chock
RLug wrench
RRatchet wrench
RAlignment bolt
Vehicles with a TIREFIT kit
CLug wrench
DTowing eye

Do not drive the vehicle. Contact a qualified
specialist workshop.
GWARNING
The tire sealant is harmful and causes
irritation. It must not come into contact with
your skin, eyes or clothing or be swallowed.
Do not inhale TIREFIT fumes. Keep tire sealant
away from children. There is a risk of injury.
If you come into contact with the tire sealant,
observe the following:
RRinse off the tire sealant from your skin
immediately with water.
RIf the tire sealant comes into contact with
your eyes, immediately rinse them
thoroughly with clean water.
RIf tire sealant is swallowed, immediately
rinse your mouth out thoroughly and drink
plenty of water. Do not induce vomiting,
and seek medical attention immediately.
RImmediately change out of clothing which
has come into contact with tire sealant.
RIf an allergic reaction occurs, seek medical
attention immediately.

electrical system in the same way as when
jump-starting (Ypage 395).
Have the vehicle transported on a transporter
or trailer.
Recovering a vehicle that has become
stuck
!When recovering a vehicle that has
become stuck, pull it as smoothly and
evenly as possible. Excessive tractive
power could damage the vehicles.
If the drive wheels have become stuck in
loose or muddy ground, pull the vehicle out
with extreme caution, especially so if the
vehicle is loaded.
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.

Fuses
Important safety notes
GWARNING
If you manipulate or bridge a faulty fuse or if
you replace it with a fuse with a higher
amperage, the electric cables could be
overloaded. This could result in a fire. There
is a risk of an accident and injury.
Always replace faulty fuses with the specified
new fuses having the correct amperage.
!For the fuse boxes in the engine
compartment and under the rear bench
seat, only use fuses with the suffix "S".
Otherwise, components or systems could
be damaged.
The fuses in your vehicle serve to close down
faulty circuits. If a fuse blows, all the
components on the circuit and their functions
stop operating.
Blown fuses must be replaced with fuses of
the same rating, which you can recognize by
the color and value. The fuse ratings are listed
in the fuse allocation chart.
If a newly inserted fuse also blows, have the
cause traced and rectified at a qualified
specialist workshop, e.g. an authorized
Mercedes-Benz Center.
Before changing a fuse
