Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis components replaced
immediately.
!Always maintain a distance of at least
11.8 in (30 cm) between the vehicle and the
power washer nozzle. Information about the
correct distance is available from the
equipment manufacturer.
Move the power washer nozzle around when
cleaning your vehicle.
Do not aim directly at any of the following:
Rtires
Rdoor gaps, roof gaps, joints, etc.
Relectrical components
Rbattery
Rconnectors
Rlights
Rseals
Rtrim
Rventilation slots
Damaged seals or electrical components
can lead to leaks or failures.
Cleaning the paintwork
!Do not affix:
Rstickers
Rfilms
Rmagnetic plates or similar items
to painted surfaces. You could otherwise
damage the paintwork.
XRemove dirt immediately, where possible,
while avoiding rubbing too hard.
XSoak insect remains with insect remover
and rinse off the treated areas afterwards.
XSoak bird droppings with water and rinse
off the treated areas afterwards.
XRemove coolant, brake fluid, tree resin,
oils, fuels and greases by rubbing gently
with a cloth soaked in petroleum ether or
lighter fluid.
XUse tar remover to remove tar stains.
XUse silicone remover to remove wax.
XUse a suitable touch-up stick, e.g. MB
Touch-Up Stick, to repair slight damage to
the paintwork quickly and provisionally. The following cannot always be completely
repaired:
Rscratches
Rcorrosive deposits
Rareas affected by corrosion
Rdamage caused by inadequate care
In such cases, visit a qualified specialist
workshop.
When water no longer forms beads on the paint surface, use the care product Paint Care,
which has been approved by smart. This is the
case approximately every three to five
months, depending on the climate conditions
and the care product used.
If the dirt has penetrated the paint surface or
if the paintwork has become dull, then the
paintwork should be cleaned. Use the care
product Paint Care, which has been approved
by smart to clean the paintwork.
Do not use these care products in the sun or on
the hood while the hood is hot.
Matte finish care
!Never polish the vehicle or the light alloy
wheels. Polishing causes the finish to
shine.
!The following may cause the paint to
become shiny and thus reduce the matte
effect:
Rstrong rubbing of the paintwork with
unsuitable materials
Rfrequent use of automatic car washes
Rwashing the vehicle in direct sunlight
!Never use paint cleaner, buffing or pol-
ishing products, or gloss preserver, e.g.
wax. These products are only suitable for
high-gloss surfaces. Their use on vehicles
with matte finish leads to considerable
surface damage (shiny, mottled areas).
Always have paintwork repairs carried out
at a qualified specialist workshop.
!Do not use wash programs with a hot wax
treatment under any circumstances.
Observe these notes if your vehicle has a
clear matte finish. This will help you to avoid
damage to the paintwork due to incorrect
treatment.
These notes also apply to light alloy wheels
with a clear matte finish.

specific and may deviate from the values in

Checking the tire pressures
Important safety notes
Observe the notes on tire pressure
(Ypage 180).
Information on air pressure for the tires on
your vehicle can be found:
Ron the vehicle's Tire and Loading Informa- tion placard on the B-pillar
Rin the tire pressure table in the fuel filler
flap (Ypage 98)
Rin the "Tire pressure" section
Checking tire pressures manually
To determine and set the correct tire pres-
sure, proceed as follows:
XRemove the valve cap of the tire that is to bechecked.
XPress the tire pressure gauge securely onto
the valve.
XRead the tire pressure and compare it with
the recommended value on the Tire and
Loading Information placard (
Ypage 180).
XIf the tire pressure is too low increase the
tire pressure to the recommended value.
XIf the tire pressure is too high, release
air. To do this, press down the metal pin in
the valve using the tip of a pen, for exam-
ple. Then check the tire pressure again
using the tire pressure checker.
XScrew the valve cap onto the valve.
XRepeat these steps for the other tires.
Tire pressure monitor
General notes
iThis function is only available in the
USA.
If a tire pressure monitor is installed, the
vehicle's wheels have sensors that monitor
the tire pressures in all four tires. The tire
pressure monitor warns you if the pressure
drops in one or more of the tires. The tire pressure monitor only functions if the cor-
responding sensors are fitted to all wheels.
Important safety notes
GWARNING
Each tire, including the spare (if provi-
ded), should be checked at least once every
two weeks when cold and inflated to the
pressure recommended by the vehicle man- ufacturer on the Tire and Loading Informa-
tion 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 indi-
cated on the Tire and Loading Information
placard or, if available, 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 moni-
toring system (TPMS) that illuminates a low
tire pressure telltale when one or more of
your tires are significantly underinflated.
Accordingly, when the low tire pressure
telltale lights up, you should stop and
check your tires as soon as possible, and
inflate them to the proper pressure. Driv-
ing on a significantly underinflated tire
causes the tire to overheat and can lead to
tire failure.
Underinflation also reduces fuel effi-
ciency and tire tread life, and may affect
the vehicle's handling and stopping abil-
ity. Please note that the TPMS is not a sub-
stitute for proper tire maintenance, and it
is the driver's responsibility to maintain
correct tire pressure, even if underinfla-
tion has not reached the level to trigger
illumination of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is com-
bined 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 repea-
ted every time the vehicle is started as long
as the malfunction exists. When the mal-
function indicator is illuminated, the sys-
tem may not be able to detect or signal low
tire pressure as intended.
TPMS malfunctions may occur for a variety
of reasons, including the installation of
incompatible replacement or alternate
tires or wheels on the vehicle that prevent
the TPMS from functioning properly. Always
check the TPMS malfunction 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 properly.
It is the driver's responsibility to set the
tire pressure to that recommended for cold
tires which is suitable for the operating sit-
uation (
Ypage 180). Note that the correct tire
pressure for the current operating situation
must first be taught-in to the tire pressure
monitor. If there is a substantial loss of
pressure, the warning threshold for the warn-
ing message is aligned to the reference val-
ues taught-in. Restart the tire pressure mon-
itor after adjusting to the cold tire pressure.
The current pressures are saved as new ref-
erence values. As a result, a warning message
will appear if the tire pressure drops sig-
nificantly.
The tire pressure monitor does not warn you of
an incorrectly set tire pressure. Observe the notes on the recommended tire pressure
(
Ypage 180).
The tire pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. if the
tire is penetrated by a foreign object. In the
event of a sudden loss of pressure, bring the
vehicle to a halt by braking carefully. Avoid
abrupt steering maneuvers. The tire pressure monitor has a yellow warn-
ing lamp in the instrument cluster for indi-
cating a pressure loss or malfunction.
Whether the warning lamp flashes or lights up
indicates whether a tire pressure is too low
or the tire pressure monitor is malfunction-
ing:
RIf the warning lamp is lit continuously, the
tire pressure on one or more tires is sig-
nificantly too low. The tire pressure mon-
itor is not malfunctioning.
RIf the warning lamp flashes for around a
minute and then remains lit constantly, the
tire pressure monitor is malfunctioning.
iA message appears in the display in addi-
tion to the warning lamp.
Observe the information on display mes-
sages (
Ypage 126).
If the tire pressure monitor is malfunction-
ing, it may take up to ten minutes for the tire
pressure warning lamp to inform you of the
malfunction. The malfunction will be indi-
cated first by the tire pressure warning lamp
flashing for approximately one minute and
then remaining lit. When the malfunction has
been rectified, the tire pressure warning
lamp goes out after a few minutes of driving.
The operation of the tire pressure monitor
can be affected by interference from radio
transmitting equipment (e.g. radio head-
phones, two-way radios) that may be being
operated in or near the vehicle.
Tire pressure monitor warning messages
If the tire pressure monitor detects a pres-
sure loss in one or more tires, a warning mes-
sage is shown in the display. The yellow warn-
ing light in the tire pressure monitor lights
up. For certain display messages a warning
tone also sounds.
RIf the Correct Tire Pressuremessage
appears in the display, the tire pressure in
at least one tire is too low. Correct the tire
pressure at the next opportunity.
RIf the Tire Pressure Warning TireFailuremessage appears in the display,
the tire pressure in one or more tires has
dropped suddenly and the tires must be
checked.
Observe the instructions and safety notes for the display messages in the "Tires" section
