Continued driving with a flat tire
If continuing to drive with a damaged tire:
1.
Avoid sudden braking and steering maneu‐
vers.
2. Do not exceed a speed of 50 mph/80 km/h.
3. Check the air pressure in all four tires at the
next opportunity.
If the tire inflation pressure in all four tires is
correct, the Tire Pressure Monitor may not
have been initialized. In this case, initialize
the system.
Possible driving distance with complete loss of
tire inflation pressure:
The possible driving distance after a loss of tire
inflation pressure depends on the cargo load
and the driving style and conditions.
For a vehicle containing an average load, the
possible driving distance is approx. 50 miles/
80 km.
When the vehicle is driven with a damaged tire,
its handling characteristics change, e.g., re‐
duced lane stability during braking, a longer
braking distance, and altered self-steering
properties. Adjust your driving style accord‐
ingly. Avoid abrupt steering maneuvers or driv‐
ing over obstacles, e.g., curbs, potholes, etc.
Because 
the possible driving distance depends
on how the vehicle is used during the trip, the
actual distance may be smaller or greater de‐
pending on the driving speed, road conditions,
external temperature, cargo load, etc.
Continued driving with a flat tire
Drive moderately and do not exceed a
speed of 50 mph/80 km/h.
A loss of tire inflation pressure results in a
change in the handling characteristics, e.g., re‐
duced lane stability during braking, a longer
braking distance and altered self-steering prop‐
erties.◀
Final tire failure
Vibrations or loud noises while driving can
indicate the final failure of the tire. Reduce speed
and stop; otherwise, pieces of the tire could come loose and cause an accident. Do not con‐
tinue 
driving, and contact your service center.◀
Message when the system was not
reset
A Check Control message is displayed.
The system detected a wheel change but was
not reset.
Warnings regarding the current tire inflation
pressure are not reliable.
Check the tire inflation pressure and reset the
system.
Malfunction The yellow warning lamp flashes and
then lights up continuously. A Check
Control message is displayed. No flat
tire can be detected.
Display in the following situations:
▷ A wheel without TPM electronics is fitted:
have 
the service center check it if necessary.
▷ Malfunction: have the system checked by
your service center.
▷ TPM could not be fully reset. Reset the sys‐
tem again.
▷ Disturbance by systems or devices with the
same 
radio frequency: after leaving the area
of the disturbance, the system automatically
becomes active again.
Declaration according to NHTSA/
FMVSS 138 Tire Pressure Monitoring
System
Each tire, including the spare (if provided)
should be checked monthly when cold and in‐
flated 
to the inflation pressure recommended by
the vehicle manufacturer on the vehicle placard
or tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la‐
bel, you should determine the proper tire infla‐
tion pressure for those tires.) As an added safety
feature, your vehicle has been equipped with a
tire pressure monitoring system (TPMS) that il‐
luminates a low tire pressure telltale when one Seite 90

Safety 

Recommended tire brands
For each tire size, the manufacturer of your ve‐
hicle recommends certain tire brands. These
can be identified by a star on the tire sidewall.
With proper use, these tires meet the highest
standards for safety and handling.
New tires
Due to technical factors associated with their
manufacture, 
tires do not achieve their full trac‐
tion potential until after an initial breaking-in pe‐
riod.
Drive conservatively for the first 200 miles/
300 km.
Retreaded tires
The manufacturer of your vehicle does not rec‐
ommend the use of retreaded tires.
Retreaded tires
Possibly substantial variations in the de‐
sign and age of the tire casing structures can
limit service life and have a negative impact on
road safety.◀
Winter tires
The manufacturer of your vehicle recommends
winter tires for winter roads or at temperatures
below +45 ℉/+7 ℃.
Although so-called all-season M+S tires do pro‐
vide better winter traction than summer tires,
they do not provide the same level of perform‐
ance as winter tires. Maximum speed of winter tires
If the maximum speed of the vehicle is higher
than the permissible speed for the winter tires,
then display a corresponding sign in the field of
vision. 
You can obtain this sign from the tire spe‐
cialist or from your service center.
Maximum speed for winter tires
Do not exceed the maximum speed for the
winter tires; otherwise, tire damage and acci‐
dents can occur.◀
Run-flat tires
For your own safety, only use run-flat tires. No
spare tire is available in the case of a flat tire. Your
service center will be glad to advise you.
Rotating wheels between axles
The manufacturer of your vehicle advises
against swapping wheels between the front and
rear axles.
This can impair the handling characteristics.
Storage
Store wheels and tires in a cool, dry place with
as little exposure to light as possible.
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.

Wheels and tires 

The wheels are composed of special rims and
tires that are self-supporting, to a limited de‐
gree.
The 
support of the sidewall allows the tire to re‐
main drivable to a restricted degree in the event
of a pressure loss.
Continued driving with a damaged tire., refer to
page  90
Changing run-flat tires
For your own safety, only use run-flat tires. No
spare tire is available in the case of a flat tire. Your
service center will be glad to advise you.
Snow chains
Fine-link snow chains
Only certain types of fine-link snow chains have
been tested by the manufacturer of your vehicle,
classified as road-safe and recommended.
Consult your service center for more informa‐
tion.
Use
Use only in pairs on the rear wheels, equipped
with the tires of the following size:
▷ 225/55 R 17.
▷ 245/45 R 18.
Follow the chain manufacturer's instructions.
Make 
 sure that the snow chains are always suf‐
ficiently tight. Retighten as needed according to
the chain manufacturer's instructions.
Do not initialize the Tire Pressure Monitor after
mounting snow chains, as doing so may result
in incorrect readings.
When driving with snow chains, briefly activate
Dynamic Traction Control if necessary.
Maximum speed with snow chains
Do not exceed a speed of 30 mph/50 km/h when
using snow chains. Snow chain detection*
The concept
When using snow chains, you should set
whether you are driving with or without snow
chains via the iDrive.
The 
snow chain detection system supports you
by automatically showing the detected state on
the Control Display.
When snow chains are in use, the rear axle steer‐
ing of the Integral Active Steering* is deacti‐
vated automatically.
At speeds above the maximum allowable speed
with snow chains of 30 mph/50 km/h, the rear
axle steering is activated again automatically.
Activating the status
1. "Settings"
2. "Tire chains"
3. "Tire chains installed"
Automatic detection
If functioning properly:
▷ Snow chains are mounted. The setting is not
activated     .
After you drive a short distance, a Check
Control message is shown and the state is
activated automatically.
Confirm the automatic activation.
▷ Snow chains are not mounted. The setting
is activated     .
At speeds above 30 mph/50 km/h, a Check
Control message is displayed. Deactivate
the status manually.
If not functioning properly:
▷ Snow chains are mounted. The setting is not
activated     .
A Check Control message is not displayed.
The 
automatic detection system is malfunc‐
tioning. Activate the status manually.

Changing wheels
Notes
The 
vehicle equipment does not include a spare
tire.
When using run-flat tires* or tire sealants, a tire
does not need to be changed immediately in the
event of pressure loss due to a flat tire.
The tools for changing wheels are available as
accessories from your service center.
Jacking points for the vehicle jack The jacking points for the vehicle jack are lo‐
cated in the positions shown. Lug bolt lock* The lug bolt lock is in the tool kit or in a storage
compartment close to the tool kit.

Maintenance
The battery is maintenance-free, i.e., the elec‐
trolyte will last for the life of the battery.
Your 
service center will be glad to advise you on
questions regarding the battery.
Battery replacement
Use approved vehicle batteries only.
Only use vehicle batteries that have been
approved for your vehicle by the manufacturer;
otherwise, the vehicle could be damaged and Seite 267
