Controls Z
Do not overload the tires by exceeding the
specified load limit as indicated on the Tire
and Loading Information placard on the
driver's door B-pillar. Overloading the tires
can overheat them, possibly causing a
blowout. Overloading
the tires can also result
in handling or steering problems, or brake
failure.
Check the tire pressure at least once a month.
Only check and correct tire pressures when
the tires are cold. Checking the tire pressure manually
In order to determine and adjust the tire
pressures, proceed as follows:
X Remove the valve cap of the tire you wish
to check.
X Press the
tire pressure gauge securely onto
the valve.
X Read the tire pressure and compare it with
the recommended value on the Tire and
Loading Information placard12
or on the tire
pressure plate on the B-pillar on the driver's
side of the vehicle.
X If necessary, increase the tire pressure to
the recommended value.
X If the tire pressure is too high, release air
by pressing down
the metal pin in the valve
using the tip of a pen, for example. Then,
check the tire pressure again using the tire
pressure gauge.
X Screw the valve cap onto the valve.
X Repeat the steps for the other tires. Tire pressure monitor
Important safety notes If a tire pressure monitor is installed, the
vehicle's wheels have sensors installed that
monitor the
tire
pressures in all four tires. The
tire pressure monitor warns you when the pressure drops in one or more of the tires. The
tire pressure monitor only functions if the
correct wheel electronics units are installed
in all wheels.
The tire pressure monitor has a yellow
0077
warning lamp in the instrument cluster for
indicating pressure loss/malfunctions (USA)
or pressure loss
(Canada). Depending on how
the warning lamp flashes or lights up, an
underinflated tire or a malfunction in the tire
pressure monitor is displayed:
R if the 0077 warning lamp is lit continuously,
the tire pressure on one or more tires is
significantly too low. The tire pressure
monitor is not malfunctioning.
R USA only: if the 0077 warning lamp flashes
for 60 seconds and then remains lit
constantly, the tire pressure monitor is
malfunctioning. G
Warning
Each tire, including the spare (if provided),
should be checked at least once a month
when cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer on the Tire and Loading
Information placard on the driver’s door B-
pillar or the
tire inflation 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 Information placard
or the tire inflation pressure label, you should
determine the proper tire inflation 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
pressure 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 underinflated tire causes the tire
to overheat and can lead to tire failure.

i The tire pressure values indicated by the
on-board computer may differ from those
measured at a gas station using a pressure
gauge. The on-board computer will
generally give you a more exact value.

If the 0077 tire pressure warning lamp
flashes for just 60 seconds and then is lit

shows
this at the latest after
ten minutes.

A message is displayed and the 0077 tire
pressure warning lamp in the instrument
cluster comes on if the pressure of one or
more tires drops significantly.
The tire pressure is shown in two red
rectangles. The pressure of the tire
concerned is shown in one of the rectangles
(Y page 199). A warning tone also sounds.
i USA only:
If the 0077 tire pressure warning lamp
flashes for just 60 seconds and then is lit

If a malfunction of the tire pressure monitor

Reactivating the tire pressure monitor In most cases, the tire pressure monitor
detects the new reference values
automatically, e.g. after you have:
R
changed the tire pressure
R changed wheels or tires
R installed new wheels or tires
If you wish to define new reference values
manually:
X Refer to the table on the tire data labels
(Y page 256) to make sure that the
pressure of all four tires is set correctly.
Observe the notes on tire pressures in the
"Tires and wheels" section ( Y page 280).260
