[ i ] Tip s
• In the case of an intentional loss of air pressure, for example,
when re -adjusting tire pressure, this has to be stored again after
wards :::::,
page 45.
• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambient air temperature.
• The ye llow symbol disappears, when the tire pressure is
corrected and the new pressure is stored in the system=:>
page 45.
• After changing a wheel or rep lacing a wheel with the spare tire
you have to adjust the tire pressures on all wheels . In addition, you
must then initialize the new tire pressures in the tire pressure moni
toring system=:>
page 46. •
Storing tire pressures
Correct storage of specified pressure is the basic require
ment for reliable tire pressure monitoring.
Fi g. 27 Car: Tire pres

In order for the tire pressure monitoring system to operate
appropriately, you have to re -save the specified pressures in
the MMI whenever you adjust tire pressures, for example
when the load condition of your vehic le changes. Proceed
as follows :

[ i ] Tips
• The tire pressure is shown on the tire pressure label. On USA
vehicles, the tire pressure labe l is located on the driver's side B
pillar. On Canada vehicles, the tire pressure label is located either on
the driver's side B -pillar or inside the fuel filler f lap . T he tire pressure
label lists the recommended cold tire inflation pressures for the
vehicle at its maximum capacity weight and the tires that were on
your vehicle at the time it was manufactured. For recommended tire pressures for normal load conditions, please see chapter

Mounting locations
Safe installation of a roof rack requires that the rack
supports are mounted between the small arrows marked inside the door frames on all four doors.
/4
Mounting
Fig . 96 Front and rear
markings
The roof rack system must be installed exactly according to the
instructions provided .
Mount the roof racks supports in the side roof moldings. Make sure
to position the supports on
all four doors between the points
marked by small arrows~ fig. 96. The markings can only be seen
when the doors are open . •
Loading the roof rack
Always distribute loads evenly. Make sure anything on the
roof rack is securely tied down.
- Always distribute the loads on the roof rack even ly.
Always attach items to the roof rack securely before you
drive off.
The maximum perm issible roof weight is 220 lb (100 kg). The roof
weight is made up of the weight of the roof rack system and the
weight of the object being transpor ted.
When using a roof rack system which has a lower load carrying
capacity, you must not use up the total maximum permissible load
carrying capaci ty specified above. Instead, you should load the roof
rack system only to the maximum capacity specified by the manu
facturer o f the roof rack syst em .
& WARNING
Weak, damaged or improper straps used to secure items to the
roof rack can fail during hard braking or in a collision and cause
serious personal injury.
• Make sure the roof rack is installed exactly as specified above
=> page 102.
• Always use suitable mounting straps for securing items to the
roof rack to help prevent items from shifting or flying forward.
• Items on the roof rack must always be securely mounted .
• The use of a roof rack can negatively affect the way a vehicle
handles . Cargo that is large, heavy, bulky, long or flat will have a
greater negative influence on the vehicle's aerodynamics, center
of gravity and overall handling . Always drive slowly, avoid sudden
braking and maneuvers when transporting cargo on the roof of
your vehicle.
• Never exceed the maximum permissible load carrying capacity
of the roof of your vehicle, the permissible axle weights and the
permissible total weight of your vehicle=>
page 361, "Weights".
• Always drive slowly, avoid sudden braking and maneuvers
when transporting cargo on the roof of your vehicle.
For the sake of the environment
Sometimes it may be easier to leave a roof rack installed even
though you are not using it. Due to the increased air resis tance your _..

Intelligent technology
Notice about data recorded by
vehicle control modu les
Your vehicle is not equipped with an Event Data Recorder (EDR),
installed by some manufacturers for the express purpose of
capturing data for retrieval after an accident or crash event . EDR's
are sometimes called "crash recorders" .
Some state laws restrict the retrieva l or downloading of data stored
by EDR's that were insta lled in a vehicle for the express purpose of
retrieving data after an accident or crash event without the owner's
consent.
Although your vehicle is not equipped with an EDR, it is equipped
with a number of electronic control modules for various vehicle systems such as, for example, engine function, emission control, as
well as for the airbags and safety belts.
These electronic control modules also record vehicle-related data during norma l vehicle operation for diagnost ic and repair purposes .
The recording capacity of the electronic control modules is limited
to data (no sound is recorded) and only a small amount of data is
actually recorded over a very limited period of time and stored when
a system fault or other condition is sensed by a control unit. Some
of the data then stored may relate to vehicle speed, direction, braking as well as restraint system use and performance in the
event of a crash or other condition . Stored data can only be read and
down loaded with special equipment .•
Electron ic Stabilizat ion Program (ESP)
General =nformation
The ESP improves the vehicle stability.
(
Fi g. 225 C ente r
co nso le w it h ES P
swi tch
ESP is designed to he lp you maintain vehic le control in situations
where the car approaches the limits of "grip", especia lly when
accelerating and cornering. ESP reduces the risk of skidding and
improves stabil ity under all road conditions .
T he system operates across the entire speed range in combination
with the ABS system. If the Anti-Lock Brake System (ABS) malfunc
tions, the ESP wil l also shut down .
How th e sys te m w ork s
The Anti -Lock Brake System (ABS) , Electronic Differential Lock (EDU
and the Anti-Slip Regulation System (ASR) are integrated in the e lec
tronic stabi lization program . In addition to the data provided by
these functions, the ESP control unit requires additional measure ment data provided by high performance sensors . The rotational
speed of the vehic le about its vertical axis, vehicle acce leration in
the fore-and-aft and lateral directions, the brake pressure and the steering angle are al l measured .

& WARNING (continued)
crashes and serious personal injuries . Have worn or damaged tires
replaced immediately.
• Tires age even if they are not being used and can fail suddenly,
especially at high speeds. Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
low speed.
Glossary of tire and loading terminology
Accessory weight
means the combined weight (in excess of those standard items
which may be replaced) of automatic transmission, power steering,

& WARNING (continued)
• Never mount used tires on your vehicle if you are not sure of
their "previous history." Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control.
• If you notice unusual vibration or if the vehicle pulls to one side
when driving, always stop as soon as it is safe to do so and check
the wheels and tires for damage . •
Cold tire inflation pressure
means the tire pressure recommended by the vehicle manufacturer
for a tire of a designated size that has not been driven for more than
a couple of miles (kilometers) at low speeds in the three hour period

Ti re pressure ge nerally refe rs to the am ount of air in a tire tha t it
needs it to do its job and safely carry the combined load of the entire
veh icle and i ts contents. Tire pressu re is measured in kilopascals
(kPa ), the internationa l measuring uni t and in pounds per square
