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

(Ypage 126) and the indicator and warning
lamps in the instrument cluster in the "Tires" section (
Ypage 139).
Restarting the tire pressure monitor
When you restart the tire pressure monitor,
all existing warning messages are deleted
and the warning lamps go out. The monitor
uses the currently set tire pressures as the
reference values for monitoring. In most
cases, the tire pressure monitor will auto-
matically detect the new reference values
after you have changed the tire pressure.
However, you can also define reference values
manually as described here. The tire pres-
sure monitor then monitors the new tire pres-
sure values.
XSet the tire pressure to the value recom-
mended for the corresponding driving sit-
uation on the Tire and Loading Information
placard on the B-pillar on the driver's side
(
Ypage 180).
Additional tire pressure values for dif-
ferent loads can also be found on the tire
pressure table on the inside of the fuel
filler flap (
Ypage 180).
XMake sure that the tire pressure is correct on all four wheels.
On-board computer with a color display
XTo restart the tire pressure monitor: press
the 0063 or0064 button on the steering
wheel to select the Settings
menu and
press 0076on the steering wheel to con-
firm.
XPress the 0063or0064 button to select the
TirePressureMonitorsubmenu and con-
firm with 0076.
The Tire Pressure Monitor Use Cur‐
rentPressuresAsNewReferenceVal‐ues?message appears in the display.
If you wish to confirm the restart:
XPress the 0063or0064 button to select yesand press the0076button to confirm.
The Tire Pressure Monitor Restarted
message appears in the display.
XPress 0076to confirm.
After a short while, the message is also
hidden without pressing the 0076button.
After driving for a few minutes, the system
checks whether the current tire pressures are within the specified range. The new
tire pressures are then accepted as refer-
ence values and monitored.
iIf the
Tire Pressure Monitor Restar‐tedmessage does not appear after approx-
imately 5 seconds, the restart was not suc-
cessful. If this occurs, repeat the restart.
If you wish to cancel the restart:
XPress the 0063or0064 button to select noand press the0076button to confirm.
The tire pressure values stored at the last
restart will continue to be monitored.

Loading the vehicle
Instruction labels for tires and loads
GWARNING
Overloaded tires can overheat, causing a
blowout. Overloaded tires can also impair
the steering and driving characteristics
and lead to brake failure. There is a risk of
accident.
Observe the load rating of the tires. The
load rating must be at least half of the GAWR
of your vehicle. Never overload the tires by exceeding the maximum load.
Two instruction labels on your vehicle show
the maximum possible load.
(1) The Tire and Loading Information plac- ard is on the B-pillar on the driver's
side. The Tire and Loading Information
placard shows the maximum permissible
number of occupants and the maximum
permissible vehicle load. It also con-

All passenger car tires must conform to the
statutory safety requirements in addition to
these grades.
iThe actual values for tires are vehicle-
specific and may deviate from the values in
the illustration.
Treadwear
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested under controlled conditions on a specified
U.S. government course. For example, a tire
graded 150 would wear one and one-half times
as well on the government test track as a tire
graded 100.
The relative performance of tires depends
upon the actual conditions of their use, how- ever, and may depart significantly from the
norm due to variations in driving habits,
service practices and differences in road
characteristics and climate conditions.
Traction
GWARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
!Avoid wheelspin. This can lead to damage
to the drive train.
The traction grades – from highest to lowest –
are AA, A, B and C. Those grades represent the
tire's ability to stop on wet pavement as
measured under controlled conditions on
specified government test surfaces of
asphalt and concrete. A tire marked C may
have poor traction performance.
The safe speed on a wet, snow covered or icy
road is always lower than on dry road surfa-
ces.
You should pay special attention to road con-
ditions when temperatures are around freez-
ing point.
smart recommends a minimum tread depth of
00CF in (4 mm) on all four winter tires. Observe
the legally required minimum tire tread
depth (
Ypage 178). Winter tires can reduce
the braking distance on snow-covered surfa- ces in comparison with summer tires. The
braking distance is still much further than on
surfaces that are not icy or covered with snow.
Take appropriate care when driving.
Further information on winter tires (M+S
tires) (
Ypage 179).
Temperature
GWARNING
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive
speed, underinflation, or excessive load-
ing, either separately or in combination,
can cause excessive heat build-up and pos- sible tire failure.
The temperature grades are A (the highest), B
and C. They represent the tire's resistance to
the generation of heat and its ability to dis-
sipate heat when tested under controlled con-
ditions on a specified indoor laboratory test
wheel. Sustained high temperature can cause
the material of the tire to degenerate and
reduce tire life, and excessive temperature
can lead to sudden tire failure. The grade C
corresponds to a level of performance which
all passenger car tires must meet under the
Federal Motor Vehicle Safety Standard No.
109. Grades B and A represent higher levels of
performance on the laboratory test wheel than
the minimum required by law.
