Wheels and tires

Rotating wheels between axles

Changing run-flat tires

Different wear patterns can occur on the front

and rear axles depending on individual driving

conditions. The tires can be rotated between

the axles to achieve even wear. Further infor‐

mation is available from a dealer’s service cen‐

ter or another qualified service center or repair

shop. After rotating, check the tire pressure

and correct, if needed.

For your own safety, only use run-flat tires. No

spare tire is available in the case of a flat tire.

A dealer’s service center will be glad to answer

additional questions at any time.

Repairing a flat tire

Rotating the tires between the axes is not per‐

missible on vehicles with different tire sizes or

rim sizes on the front and rear axles.

Safety measures

▷

Park the vehicle as far away as possible

from passing traffic and on solid ground.

▷

Switch on the hazard warning system.

Storage

Secure the vehicle against rolling away by

setting the parking brake.

Store wheels and tires in a cool, dry place with

as little exposure to light as possible.

▷

Turn the steering wheel until the front

wheels are in the straight-ahead position

and engage the steering wheel lock.

Always protect tires against all contact with oil,

grease and fuels.

Do not exceed the maximum tire inflation pres‐

sure indicated on the side wall of the tire.

Have all vehicle occupants get out of the

vehicle and ensure that they remain out‐

side the immediate area in a safe place,

such as behind a guardrail.

Run-flat tires

▷

If necessary, set up a warning triangle at an

appropriate distance.

Label

Mobility System

Concept

With the Mobility System, minor tire damage

can be sealed temporarily to enable continued

travel. To accomplish this, sealant is pumped

into the tires, which seals the damage from the

inside.

RSC label on the tire sidewall.

The compressor can be used to check the tire

inflation pressure.

The wheels consist of tires that are self-sup‐

porting, to a limited degree, and possibly spe‐

cial rims.

General information

The support of the sidewall allows the tire to

remain drivable to a restricted degree in the

event of a tire inflation pressure loss.

▷

Follow the instructions on using the Mobi‐

lity System found on the compressor and

sealant container.

Follow the instructions for continued driving

with a flat tire.

▷

Use of the Mobility System may be ineffec‐

tive if the tire puncture measures approx.

1/8 inches/4 mm or more.

Compressor

Contact a dealer’s service center or an‐

other qualified service center or repair

shop if the tire cannot be made drivable.

▷

If possible, do not remove foreign bodies

that have penetrated the tire.

Pull the speed limit sticker off the sealant

container and apply it to the steering

wheel.

▷

The use of a sealant can damage the TPM

wheel electronics. In this case, have the

electronics checked at the next opportu‐

nity and have them replaced, if needed.

Filling the tire with sealant

1. Shake the sealant container.

Sealant container

2. Pull the connection hose fully out of the

compressor housing. Do not kink the hose.

Observe use-by date on the sealant container.

3. Screw the connection hose onto the con‐

nector of the sealant container.

6. With the compressor switched off, insert

the plug into the power socket inside the

vehicle.

4. Insert the sealant container on the com‐

pressor housing in an upright position.

7. With the ignition turned on or the engine

running, switch on the compressor.

5. Screw the filling hose of the sealant con‐

tainer onto the tire valve of the nonworking

wheel.

DANGER

If the exhaust pipe is blocked or ventila‐

tion is insufficient, harmful exhaust gases can

enter into the vehicle. The exhaust gases con‐

tain carbon monoxide, an odorless and color‐

less but highly toxic gas. In enclosed areas, ex‐

haust gases can also accumulate outside of

the vehicle. There is danger to life. Keep the

exhaust pipe free and ensure sufficient ventila‐

tion.◀

NOTE

The compressor can overheat during ex‐

tended operation. There is a risk of property

damage. Do not run the compressor for more

than 10 min.◀

Let the compressor run for approx. 3 to 8 mi‐

nutes to fill the tire with sealant and achieve a

tire inflation pressure of approx. 2.5 bar.

Wheels and tires

Mobility

While the tire is being filled with sealant, the

tire inflation pressure may sporadically reach

approx. 5 bar. Do not switch off the compres‐

sor at this point.

Correcting the tire inflation pressure

1. Stop at a suitable location.

2. Screw the connection hose of the com‐

pressor directly onto the tire valve stem.

If a tire inflation pressure of 2 bar is not

reached:

3. Insert the connector into the power socket

inside the vehicle.

1. Switch off the compressor.

4. Correct the tire inflation pressure to

2.5 bar.

2. Unscrew the filling hose from the wheel.

3. Drive 33 ft/10 m forward and back to dis‐

tribute the sealant in the tire.

▷

Increase pressure: with the ignition

turned on or the engine running, switch

on the compressor.

4. Inflate the tire again using the compressor.

▷

To reduce the pressure: press the but‐

ton on the compressor.

If a tire inflation pressure of 2 bar cannot be

reached, contact your dealer’s service cen‐

ter or another qualified service center or

repair shop.

Continuing the trip

Do not exceed the maximum permissible

speed of 50 mph/80 km/h.

Stowing the Mobility System

1. Unscrew the filling hose of the sealant con‐

tainer from the wheel.

Reinitialize the Flat Tire Monitor.

Reinitialize the Tire Pressure Monitor.

2. Unscrew the connection hose of the com‐

pressor from the sealant container.

Replace the nonworking tire and the sealant

container of the Mobility System as soon as

possible.

3. Connect the filling hose of the sealant con‐

tainer previously connected to the tire

valve with the available connector on the

sealant container.

Snow chains

This prevents leftover sealant from escap‐

ing from the container.

Fine-link snow chains

The manufacturer of your vehicle recommends

use of fine-link snow chains. Certain types of

fine-link snow chains have been tested by the

manufacturer of the vehicle and recommended

as road-safe and suitable.

4. Wrap the empty sealant container in suita‐

ble material to avoid dirtying the cargo

area.

5. Stow the Mobility System back in the vehi‐

cle.

Information regarding suitable snow chains is

available from a dealer’s service center or an‐

other qualified service center or repair shop.

Distributing the sealant

Immediately drive approx. 5 miles/10 km to en‐

sure that the sealant is evenly distributed in the

tire.

Use

WARNING

Do not exceed a speed of 50 mph/80 km/h.

With the mounting of snow chains on un‐

suitable tires, the snow chains can come into

contact with vehicle parts. There is a risk of ac‐

cidents or risk of property damage. Only mount

If possible, do not drive at speeds less than

12 mph/20 km/h.
