Tyre pressure

Information on tyre pressure

../../../../global/pictures_mb/symb_achtung.png

WARNING

Underinflated or overinflated tyres pose the following risks:

  • the tyres may burst, especially as the load and vehicle speed increase.

  • the tyres may wear excessively and/or unevenly, which may greatly impair tyre traction.

  • the driving characteristics, as well as steering and braking, may be greatly impaired.

There is a risk of an accident.

Observe the recommended tyre pressure and check the tyre pressure of all the tyres including the spare wheel:

  • at least every two weeks

  • when the load changes

  • before embarking on a longer journey

  • for changed operating conditions, e.g. off-road driving

If necessary, correct the tyre pressure.

../../../../global/pictures_mb/symb_achtung.png

WARNING

If you fit unsuitable accessories onto tyre valves, the tyre valves may be overloaded and malfunction, which can cause tyre pressure loss. Due to their design, retrofitted tyre pressure monitors keep the tyre valve open. This can also result in tyre pressure loss. There is a risk of accident.

Only screw standard valve caps or valve caps specifically provided by Mercedes-Benz for your vehicle onto the tyre valve.

../../../../global/pictures_mb/symb_achtung.png

WARNING

If the tyre pressure drops repeatedly, the wheel, valve or tyre may be damaged. Tyre pressure that is too low may result in a tyre blow-out. There is a risk of accident.

  • Check the tyre for foreign objects.

  • Check whether the wheel is losing air or the valve is leaking.

If you are unable to rectify the damage, contact a qualified specialist workshop.

The pressure difference between tyres on any one axle must be no greater than 10 kPa (0.1 bar/1.5 psi).

../../../../global/pictures_mb/symb_baum.png

Environmental note

Check the tyre pressure regularly, at least every 14 days.

You will find a table of recommended tyre pressures inside the fuel filler flap beneath the fuel cap and in the "Tyre pressure table" section more. Tyre pressures are specified for different load conditions. These are defined in the table as different numbers of passengers and amounts of luggage.

The tyre size precedes the tyre pressures. The tyre pressure value only applies to this size of tyre.

The tyre pressure values for an unladen/laden vehicle depend on the permissible axle loads of the front and rear axles. You can find this data on the vehicle identification plate on the door frame of the driver's door more.

Use a suitable pressure gauge to check the tyre pressure. The outer appearance of a tyre does not permit any reliable conclusion about the tyre pressure.

On vehicles fitted with the electronic tyre pressure monitor, the tyre pressure can be checked using the on-board computer.

Set the correct tyre pressure before loading the vehicle. Once the vehicle is laden, check the tyre pressures and correct them if necessary.

If possible, only correct tyre pressures when the tyres are cold.

The tyres are cold:

  • if the vehicle has been parked with the tyres out of direct sunlight for at least 3 hours and

  • if the vehicle has not been driven further than 1.6 km

Depending on the ambient temperature, the speed at which you are driving and the load on the tyres, the tyre temperature and thus the tyre pressure change by approximately 10 kPa per 10 corposwgl_2020.png (0.1 bar/1.5 psi). Take this into account when checking the pressure of warm tyres. Only correct the tyre pressure if it is too low for the current operating conditions.

Only correct the tyre pressures when the tyres are warm if:

  • the levels fall below the values stated in the tyre pressure table when the vehicle is laden and the temperature of the tyre is taken into account more .

  • the levels fall below the values stated in the tyre pressure table when the vehicle is unladen and the temperature of the tyre is taken into account.

Driving with tyre pressure that is too high or too low can:

  • shorten the service life of the tyres

  • cause increased tyre damage

  • have a negative effect on handling characteristics and thus the driving safety (e.g. aquaplaning)

Tyre pressure monitor

Important safety notes

Vehicles with a tyre pressure monitor are equipped with sensors in the wheels that monitor the tyre pressure of all four tyres. The tyre pressure monitor monitors the pressure in all four tyres; you set this pressure when you activate the tyre pressure monitor. The tyre pressure monitor warns you if the pressure drops in one or more of the tyres. The tyre pressure monitor only functions if the corresponding sensors are fitted to all wheels.

You should always adjust the tyre pressures according to the vehicle load. Restart the tyre pressure monitor if you change the tyre pressure.

The tyre pressure monitor does not warn you if a tyre pressure is incorrect. Observe the notes on the recommended tyre pressure more.

The tyre pressure monitor is not able to warn you of a sudden loss of pressure, e.g. following penetration by a foreign object. In this event, brake the vehicle until it comes to a standstill. Do not carry out any sudden steering manoeuvres.

Only vehicles with steering wheel buttons: the on-board computer displays information on tyre pressures. After a few minutes of driving, the current tyre pressure of each tyre is shown in the on-board computer.

The tyre pressure values indicated by the on-board computer may differ from those measured at a filling station with a pressure gauge. The tyre pressures shown by the on-board computer refer to those measured at sea level. At high altitudes, the tyre pressure values indicated by a pressure gauge are higher than those shown by the on-board computer. In this case, do not reduce the tyre pressures.

If radio transmitting equipment (e.g. cordless headphones, two-way radios) is operated inside the vehicle or in the vicinity of the vehicle, this can interfere with the operation of the tyre pressure monitor.

Checking the tyre pressure electronically (vehicles with steering wheel buttons)

images/imgb3b98604351f15140ce4008d24db4429_1_en_GB_JPG72.jpg Tyre pressure display

Using the steering wheel buttons

Turn the key to position 2 in the ignition lock.

Press the mbsymb5_inv_0056.png or mbsymb5_inv_0055.png button repeatedly until the standard display is shown more.

Press the mbsymb5_inv_003a.png or mbsymb5_inv_0039.png button repeatedly until the current pressure of the individual tyres is shown in the display.

If the vehicle is parked for longer than 20 minutes or you then drive at less than 30 km/h, the Tyre press. displayed after driving for several minutes message appears.

../../../../global/pictures_mb/symb_info.png

The tyre pressure values shown in the display may differ from those measured at a filling station using a pressure gauge. The on-board computer will generally give you a more exact value.

Tyre pressure loss warning system

Vehicles without steering wheel buttons

If the tyre pressure monitor detects a significant pressure loss on one or more tyres, the mbsymb1_inv_0068.png tyre pressure loss warning lamp lights up in the instrument cluster more.

Vehicles with steering wheel buttons

If the tyre pressure monitor detects a significant pressure loss on one or more tyres, the on-board computer displays a warning message. The mbsymb1_inv_0068.png tyre pressure loss warning lamp in the instrument cluster more lights up. A warning tone also sounds.

If the tyre pressure monitor has detected the affected wheel, the wheel position is also displayed.

Restarting the tyre pressure monitor

When you restart the tyre pressure monitor, the currently set tyre pressures are taken as reference values for monitoring.

In most cases, the tyre pressure monitor detects the new reference values automatically, e.g. after you have:

  • changed the tyre pressure

  • changed wheels or tyres

  • fitted new wheels or tyres

However, you can also define reference values manually as described here.

Before restarting the tyre pressure monitor:

By referring to the table behind the fuel filler flap or the tyre pressure table,more make sure that the pressure on all four tyres is correct for the present vehicle load.

Observe the notes on tyre pressure when doing so more.

Restarting the tyre pressure monitor (vehicles with steering wheel buttons):

Turn the key to position 2 in the ignition lock.

Press the mbsymb5_inv_0056.png or mbsymb5_inv_0055.png button on the steering wheel repeatedly until the standard display is shown more.

Press the mbsymb5_inv_003a.png or mbsymb5_inv_0039.png button on the steering wheel repeatedly until the current pressure of the individual tyres is displayed or the display shows the following message:

Tyre press. displayed after driving for several minutes

Press the mbsymb6_inv_0039.png reset button on the instrument cluster.

The display shows the following message:

Monitor current tyre pressure?

Press the mbsymb5_inv_0057.png button on the steering wheel.

The display shows the following message:

Tyre press. monitor reactivated

The tyre pressure monitor activation process has begun. The tyre pressures measured for the individual wheels are stored as the new reference values, provided that the tyre pressure monitor considers them to be plausible.

If you wish to cancel the restart:

Press the mbsymb5_inv_0058.png button on the steering wheel.
