You can find information on tire pressure for the
vehicle's factory-installed tires on the following
labels:
Tire and Loading Information placard on the
R
B‑pillar of your vehicle (
page 336).
/
Tire pressure table on the inside of the fuel
R
filler flap (
page 331).
/
Observe the maximum tire pressure
(
page 342).
/
Use a suitable pressure gauge to check the tire
pressure. The outer appearance of a tire does
not permit any reliable conclusion about the tire
pressure.
Vehicles with a tire pressure monitoring sys‐
tem: You can also check the tire pressure using
the on-board computer.
Only correct tire pressure when the tires are
cold. Conditions for cold tires:
The vehicle has been parked with the tires
R
out of direct sunlight for at least three hours.
The vehicle has traveled less than 1 mile
R
(1.6 km).
A rise in the tire temperature of 18 °F (10 °C)
increases the tire pressure by approx. 10 kPa
(0.1 bar/1.5 psi). Take this into account when
checking the tire pressure of warm tires.
The tire pressure recommended for increased
load/speed in the tire pressure table can affect
the ride comfort.
& WARNING Risk of accident due to
unsuitable accessories on tire valve
If you mount unsuitable accessories onto tire
valves, the tire valves may be overloaded and
malfunction, which can cause a loss of tire
pressure. Aftermarket tire pressure monitor‐
ing systems will cause the tire valve to
remain open, depending on the design. This
can also result in a loss of tire pressure.
