Pressure Loss Warning - Mercedes-Benz CLS Operator's Manual

Check the tire pressure at least once a month.
Only check and correct tire pressures when
the tires are cold ( Y page 317).
Checking tire pressure manually
To determine and set the correct tire
pressure, proceed as follows:
X
Remove the valve cap of the tire that is to
be checked.
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 placard on the
B-pillar on the driver's side of your 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 these steps for the other tires.

Important safety notes
While the vehicle is in motion, the tire
pressure loss warning system monitors the
set tire pressure using the rotational speed of
the wheels. This enables the system to detect
significant pressure loss in a tire. If the speed
of rotation of a wheel changes as a result of
a loss of pressure, a corresponding warning
message will appear in the multifunction
display.

WARNING
Check Tire Pressure Soon
If the
appears in the multifunction display, one or
more tires are significantly underinflated.
Stop the vehicle as soon as possible and

The function of the tire pressure loss warning
system is limited or delayed if:

R
I n f o r ma t i o n P r o v i d e d b y :
inflate the tires to the pressure specified on
the vehicle's Tire and Loading Information
placard or (where available) in the tire
pressure table.
Driving on a significantly underinflated tire
causes the tire to overheat and can lead to
tire failure. Underinflation also reduces fuel
efficiency and tire tread life, and may affect
the vehicle's handling and stopping ability.
Check all tires when cold, including the spare
tire, at least once a month. The tires should
be inflated to the recommended pressure.
This information can be found:
on the Tire and Loading Information placard

on the B-pillar on the driver's side
or
in the table for the tire pressure on the

WARNING
The tire pressure loss warning system does
not provide a warning for wrongly selected tire
inflation pressures. Always adjust tire
inflation pressure according to the Tire and
Loading Information placard on the driver's
door B-pillar or on the tire inflation pressure
label located on the inside of the fuel filler flap.
The tire pressure loss warning system does
not replace regular checks of the tire inflation
pressures since a gradual pressure loss in
more than one tire cannot be detected by the
tire pressure loss warning system.
The tire pressure loss warning system is not
able to issue a warning due to a sudden
dramatic loss of tire inflation pressure (e.g.
tire blowout caused by a foreign object). In
this case bring the vehicle to a halt by carefully
applying the brakes and avoiding abrupt
steering maneuvers.
snow chains are mounted to your vehicle's
tires.
road conditions are wintry.
