290 Wheels and tires
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.
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).
The vehicle's tires heat up when driving. As the
temperature of the tires increases, so too does
the tire pressure.
Vehicles with tire pressure monitoring sys‐
tem: You can also see the tire pressure in the
driver's display.
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 valves
If you mount unsuitable accessories onto tire
valves, the tire valves may be overloaded and
malfunction, which can cause tire pressure
loss.
Only screw standard valve caps or valve
#
caps specifically approved by
Mercedes-Benz for your vehicle onto
the tire valve.
Tire pressure table
The tire pressure table is on the inside of the
fuel filler flap.
% The data shown in the images is example
data.
If one or more tire sizes precede a tire pressure,
the following tire pressure information is only
valid for those tire sizes and their respective
load condition.
The load conditions "partially laden" and "fully
laden" are defined in the table for different num‐
bers of passengers and amounts of luggage. The
actual number of seats may differ from this.
