191 Checking tire inflation pressure
Regularly check your tire inflation pressure
at least once a month.
Check and adjust the tire inflation pressure
when the tires are cold. The tires can be con
sidered cold if the vehicle has been parked
for at least 3 hours or driven less than 1 mile
(1.6 km).
If you check the tire inflation pressure when
the tires are warm (the vehicle has been
driven for several miles or sitting less than
3 hours), the reading will be approximately
4 psi (0.3 bar) higher than the cold reading.
This is normal. Do not let air out to match the
specified cold tire inflation pressure. Other
wise, the tire will be underinflated.Checking tire inflation pressure manually
Follow the steps below to achieve correct tire
inflation pressure:
>Remove the cap from the valve on one tire.
>Firmly press a tire gauge onto the valve.
>Read tire inflation pressure on tire gauge
and check against the recommended tire
inflation pressure on the Tire and Loading
Information placard on the driver’s door
Bpillar (
page 185). If necessary, add air
to achieve the recommended tire inflation
pressure.
i
If you have overfilled the tire, release tire
inflation pressure by pushing the metal stem
of the valve with e.g. a tip of a pen. Then
recheck the tire inflation pressure with the
tire gauge.
>Install the valve cap.
>Repeat this procedure for each tire.

Warning!
Follow recommended tire inflation
pressures.
Do not underinflate tires. Underinflated
tires wear excessively and/or unevenly,
adversely affect handling and fuel econ
omy, and are more likely to fail from being
overheated.
Do not overinflate tires. Overinflated
tires can adversely affect handling and
ride comfort, wear unevenly, increase
stopping distance, and result in sudden
deflation (blowout) because they are
more likely to become punctured or
damaged by road debris, potholes etc.
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 Bpillar. Overload
ing the tires can overheat them, possibly
causing a blowout. Overloading the tires
can also result in handling or steering
problems, or brake failure.
