Calibrating the front seats

WARNING

There is a risk of jamming when moving

the seats. There is a risk of injury or risk of

property damage. Make sure that the area of

movement of the seat is clear prior to any ad‐

justment.◀

The indicator lamp for the front-seat passen‐

ger airbags indicates the operating state of the

front-seat passenger airbags.

The lamp indicates whether the airbags are ei‐

ther activated or deactivated.

A corresponding message appears on the

Control Display.

▷

The indicator lamp lights up

when a child is properly

seated in a child restraint fix‐

ing system or when the seat

is empty. The airbags on the

front passenger side are not

activated.

1. Press the switch and move the respective

seat all the way forward, until it stops.

2. Press the switch forward again. The seat

still moves forward slightly.

3. Readjust the seat to the desired position.

The calibration procedure is completed when

the message on the Control Display disap‐

pears.

▷

The indicator lamp does not light up when,

e.g., a correctly seated person of sufficient

size is detected on the seat. The airbags

on the front passenger side are activated.

If the message continues to be displayed, re‐

peat the calibration.

If the message does not disappear after a re‐

peat calibration, have the system checked as

soon as possible.

Detected child restraint systems

The system generally detects children seated

in a child restraint system, particularly in child

restraint systems required by NHTSA at the

point in time when the vehicle was manufac‐

tured. After installing a child restraint system,

make sure that the indicator light for the front-

seat passenger airbags lights up. This indi‐

cates that the child restraint system has been

detected and the front-seat passenger airbags

are not activated.

Tire Pressure Monitor TPM

Concept

The system monitors tire inflation pressure in

the four mounted tires. The system warns you

if there is a significant loss of pressure in one

or more tires.

tire inflation pressure.

WARNING

Your vehicle handles differently with a

run-flat with no or low inflation pressure; for in‐

stance, your lane stability when braking is re‐

duced, braking distances are longer and the

self-steering properties will change. There is a

risk of an accident.

No reset was performed for the sys‐

tem. The system issues a warning

based on the tire inflation pressures

stored during the last reset.

Measure

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

1. Identify the damaged tire.

3. Check the air pressure in all four tires at

the next opportunity.

To do this, check the air pressure in all four

tires, for instance using the tire pressure

gage of a flat tire kit.

If the tire inflation pressure in all four tires

is correct, the Tire Pressure Monitor may

not have been reset. In this case, perform

the reset.

Controls

Safety

Possible driving range with a

depressurized tire

These circumstances may cause a warning

when temperatures fall very sharply.

The possible driving range varies depending

on the how the vehicle is loaded and used, e.g.,

speed, road conditions, external temperature.

The driving range may be less but may also be

more if an economical driving style is used.

Sudden tire pressure loss

The system cannot indicate sudden serious

tire damage caused by external circumstances.

Failure to perform a reset

If the vehicle is loaded with an average weight

and used under favorable conditions, its possi‐

ble driving range will be up to 50 miles/80 km.

The system does not function properly if a re‐

set has not been carried out, for instance a flat

tire is reported though tire inflation pressures

are correct.

Vehicle handling with damaged tires

Vehicles driven with a damaged tire will handle

differently, potentially leading to conditions

such as the following:

Malfunction

The yellow warning light flashes and is

then illuminated continuously. A Check

Control message is displayed. It may

not be possible to identify tire pressure losses.

Changed self-steering properties.

Examples and recommendations in the follow‐

ing situations:

Modify your driving style. Avoid abrupt steer‐

ing maneuvers or driving over obstacles, for in‐

stance curbs or potholes.

▷

A wheel without TPM wheel electronics,

for instance an emergency wheel, is

mounted: have it checked by a dealer’s

service center or another qualified service

center or repair shop as needed.

Final tire failure

Vibrations or loud noises while driving can indi‐

cate the final failure of a tire.

▷

Malfunction: have system checked by a

dealer’s service center or another qualified

service center or repair shop.

Reduce speed and stop; otherwise, pieces of

the tire could come loose and cause an acci‐

dent.

▷

The system was unable to complete the

reset. Perform a system reset again.

Do not continue driving. Contact a dealer’s

service center or another qualified service cen‐

ter or repair shop.

Safety

Controls

vehicle has tires of a different size than the size

indicated on the vehicle placard or tire inflation

pressure label, you should determine the

proper tire inflation pressure for those tires.)

As an added safety feature, your vehicle has

been equipped with a tire pressure monitoring

system (TPMS) that illuminates a low tire pres‐

sure telltale when one or more of your tires is

significantly under-inflated. Accordingly, when

the low tire pressure telltale illuminates, you

should stop and check your tires as soon as

possible, and inflate them to the proper pres‐

sure. Driving on a significantly under-inflated

tire causes the tire to overheat and can lead to

tire failure. Under-inflation also reduces fuel ef‐

ficiency and tire tread life, and may affect the

vehicle's handling and stopping ability. Please

note that the TPMS is not a substitute for

proper tire maintenance, and it is the driver's

responsibility to maintain correct tire pressure,

even if under-inflation has not reached the

level to trigger illumination of the TPMS low

tire pressure telltale. Your vehicle has also

been equipped with a TPMS malfunction indi‐

cator to indicate when the system is not oper‐

ating properly. The TPMS malfunction indica‐

tor is combined with the low tire pressure

telltale. When the system detects a malfunc‐

tion, the telltale will flash for approximately one

minute and then remain continuously illumi‐

nated. This sequence will continue upon sub‐

sequent vehicle start-ups as long as the mal‐

function exists. When the malfunction indicator

is illuminated, the system may not be able to

detect or signal low tire pressure as intended.

TPMS malfunctions may occur for a variety of

reasons, including the installation of replace‐

ment or alternate tires or wheels on the vehicle

that prevent the TPMS from functioning prop‐

erly. Always check the TPMS malfunction tell‐

tale after replacing one or more tires or wheels

on your vehicle to ensure that the replacement

or alternate tires and wheels allow the TPMS

to continue to function properly.

FTM Flat Tire Monitor

Concept

The system detects tire inflation pressure loss

on the basis of rotation speed differences be‐

tween the individual wheels while driving.

In the event of a tire inflation pressure loss, the

diameter and therefore the rotational speed of

the corresponding wheel changes. The differ‐

ence will be detected and reported as a flat

tire.

The system does not measure the actual infla‐

tion pressure in the tires.

Functional requirements

The following conditions must be met for the

system; otherwise, reliable flagging of a loss of

tire inflation pressure is not assured:

▷

After a tire or wheel replacement, an initial‐

ization was performed with the correct tire

inflation pressure.

▷

After the tire inflation pressure was ad‐

justed to a new value, an initialization was

performed.

Status display

The current status of the flat tire monitor can

be displayed, for instance whether the RPA is

active.

Using iDrive:

1. "Vehicle info"

2. "Vehicle status"

3.

"Flat Tire Monitor (FTM)"

The status is displayed.

Initialization required

An initialization must be performed in the fol‐

lowing situations:

▷

After the tire inflation pressure has been

adjusted.

▷

After a tire or wheel replacement.
