Vehicle tool kit
General notes
Depending on the equipment version of the vehi- cle, the vehicle tool kit is:
Rin the seat base of the left front seat
Rin the rear stowage compartment
Rin the tool holder in the cargo compartment
Apart from some country-specific variants, vehi-
cles without a spare wheel are not equipped
with tire-changing tools. If your vehicle is equip-
ped with tire-changing tools, these are in the
vehicle tool kit. If the vehicle tool kit is stowed in
the driver's seat base, the jack is in a separate
holder in the cargo compartment on the right-
hand side of the vehicle next to the tailgate/rear door (
Ypage 272).
Some tools for changing a wheel are specific to
the vehicle. For more information on which tools are required and approved to perform a wheel
change on your vehicle, consult a qualified spe-
cialist workshop.
Necessary tire-changing tools can include, for
example:
Rjack
Rlug wrench
Rratchet wrench
iThe jack has a maximum weight of 7.5 kg
depending on the vehicle's equipment.
The maximum payload of the jack can be
found on the sticker on the jack itself.
The jack is maintenance-free. In the event of a malfunction, please contact a qualified spe-
cialist workshop.

Important safety notes
GWARNING
Each tire, including the spare (if provided),
should be checked at least once a month
when cold and inflated to the pressure rec-
ommended by the vehicle manufacturer on
the Tire and Loading Information placard on
the driver's door B-pillar or the tire pressure
label on the inside of the fuel filler flap. If your
vehicle has tires of a different size than the
size indicated on the Tire and Loading Infor-
mation placard or the tire pressure label, you
should determine the proper tire pressure for
those tires.
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres-
sure telltale when one or more of your tires
are significantly underinflated. Accordingly,
when the low tire pressure telltale illuminates,
you should stop and check your tires as soon
as possible, and inflate them to the proper
pressure. Driving on a significantly underin-
flated tire causes the tire to overheat and can lead to tire failure. Underinflation also
reduces fuel efficiency and tire tread life, and
may affect the vehicle's handling and stop-
ping ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv-
er's responsibility to maintain correct tire
pressure, even if underinflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale.
USA only:
Your vehicle has al so b
een equipped with a
TPMS malfunction indicator to indicate if the
system is not operating properly. The TPMS
malfunction indicator is combined with the
low tire pressure telltale. When the system
detects a malfunction, the warning lamp will
flash for approximately a minute and then
remain continuously illuminated. This
sequence will be repeated every time the vehi-
cle is started as long as the malfunction
exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS malfunc-
tions may occur for a variety of reasons,
including the mounting of incompatible
replacement or alternate tires or wheels on
the vehicle that prevent the TPMS from func-
tioning properly. Always check the TPMS mal-
function telltale after replacing one or more
tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels
allow the TPMS to continue to function prop-
erly.
It is the driver's responsibility to set the tire
pressure to the recommended cold tire pressure
suitable for the operating conditions
(
Ypage 280).
Note that the correct tire pressure for the cur-
rent operating conditions must first be pro-
gramed into the tire pressure monitor. If there is
a substantial loss of pressure, the warning
threshold for the warning message is aligned to
the reference values programed in. Restart the
tire pressure monitor after adjusting the cold
tire pressure (
Ypage 287). The current pres-
sures are saved as new reference values. This
will ensure that a warning message will only
appear if the tire pressure drops significantly.
The tire pressure monitor does not warn you if a
tire pressure is incorrect. Obs erve the note

s on
the recommended tire pressure (Ypage 280).
The tire pressure monitor is not able to warn you
of a sudden loss of pressure, e.g. following pen- etration by a foreign object. In this event, brake
the vehicle until it comes to a standstill. Avoid
sudden steering movements.
The tire pressure monitor has a yellow h
warning lamp in the instrument cluster for indi-
cating pressure loss/malfunctions (USA) or
pressure loss (Canada). Depending on how the
warning lamp flashes or lights up, an underin-
flated tire or a malfunction in the tire pressure
monitor is displayed:
Rif the h warning lamp is lit continuously,
the tire pressure on one or more tires is sig-

Oil consumption may be higher if:
RThe vehicle is new.
RYou mainly operate the vehicle under arduous
operating conditions.
RYou frequently drive at high engine speeds.
Regular maintenance is one of the preconditions
for moderate rates of consumption.
You can only estimate the oil consumption after
you have driven a considerable distance.

Brake fluid
GWARNING
The brake fluid constantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake
fluid is too low, vapor pockets may form in the
brake system when the brakes are applied
hard. This would impair braking efficiency.
There is a risk of an accident.
You should have the brake fluid renewed at
the specified intervals.
!Brake fluid corrodes paint, plastic and rub-
ber. If paint, plastic or rubber has come into
contact with brake fluid, rinse with water
immediately.
When handling, storing and disposing of brake
fluid, please observe the relevant regulations
and the important safety notes for service prod-
ucts (
Ypage 304).
Over a period of time, the brake fluid absorbs
moisture from the air. This reduces its boiling
point.
Have the brake fluid replaced at specified inter-
vals by a qualified specialist workshop.
iThere is usually a notice in the engine com-
partment to remind you when the next brake
fluid change is due.
Use only approved brake fluids that comply with the Mercedes-Benz Specifications for Service
Products. Always check for the identification
DOT 4 plus. Information about approved brake fluids can be
obtained:

Coolant
Important safety notes
GWARNING
If antifreeze comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Let the engine cool down before you add anti-
freeze. Make sure that antifreeze is not spilled
next to the filler neck. Thoroughly clean the
antifreeze from components before starting
the engine.
!Take care not to spill any coolant on painted
surfaces. You could otherwise damage the
paintwork.
When handling, storing and disposing of coolant
and antifreeze, please observe the relevant reg-
ulations and the important safety notes for oper-
ating fluids (
Ypage 304).
Coolant additive with corrosion and
antifreeze protection
!Use only approved antifreeze/corrosion
inhibitor that complies with MB Specification for Service Products, Sheet Number 325.
Using other, non-approved antifreeze/corro-
sion inhibitors may cause damage to the cool-
ant system and reduce the engine's service
life.
The coolant is a mixture of water and antifreeze
and corrosion inhibitor. It performs the following
tasks:
RAnti-corrosion protection
RAntifreeze protection
RRaises the boiling point
When the vehicle is first delivered, it is filled with
a coolant mixture that ensures adequate anti-
freeze/corrosion protection. Coolant must
remain in the engine cooling system all year
round to ensure anti-corrosion protection and a
higher boiling point, even in countries with high
outside temperatures.
