Checking the tire pressure manually

Read the tire pressure for the current operat‐
#
ing conditions from the tire and loading infor‐
mation table or the tire pressure table.
Observe the notes on tire pressure.
Remove the valve cap of the tire to be
#
checked.
Press the tire pressure gauge securely onto
#
the valve.
Read the tire pressure.
#
If the tire pressure is lower than the recom‐
#
mended value, increase the tire pressure to
the recommended value.
If the tire pressure is higher than the recom‐
#
mended value, release air. To do so, press
down the metal pin in the valve, e.g. using
the tip of a pen for example. Then check the
tire pressure again using the tire pressure
gauge.
Screw the valve cap onto the valve.

& DANGER Risk of accident due to incor‐
rect tire pressure
Every tire, including the spare (if provided),
should be checked when cold at least once a
month and inflated to the pressure recom‐
mended by the vehicle manufacturer (see
Tire and Loading Information placard on the
B-pillar on the driver's side or the tire pres‐
sure label on the inside of the fuel filler flap
of your vehicle). If your vehicle has tires of a
different size than the size indicated on the
Tire and Loading Information placard or the

tire pressure table, you need to determine
the proper tire pressure for those tires.
As an added safety feature, your vehicle has
been equipped with a tire pressure monitor‐
ing system (TPMS) that illuminates a low tire
pressure indicator lamp when one or more of
your tires are significantly underinflated.
Accordingly, if the low tire pressure indicator
lamp lights up, 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.
Underinflation also increases fuel consump‐
tion and reduces tire tread life, and may
affect the vehicle's handling and braking abil‐
ity. Please note that the TPMS is not a substi‐
tute for proper tire maintenance, and it is the
driver's responsibility to maintain correct tire
pressure, even if underinflation has not
reached the level to trigger illumination of
the TPMS low tire pressure indicator lamp.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
