2018 BMW 7 SERIES Owners Manual

Follow the instructions for continued driving
with a flat tire.
Safety
information WARNING
Your vehicle handles differently with a
run-flat with no or low inflation pressure; for in#j stance, your lane stability when braking is re#jduced, braking distances are longer and theself-steering properties will change. There is a
risk of an accident.
Drive moderately and do not exceed a speed of 50 mph/80 km/h.'

Overview

Safety
measures
'yPark the vehicle as far away as possible
from passing traffic and on solid ground.'ySwitch on the hazard warning system.'ySecure the vehicle against rolling away by setting the parking brake.'yTurn the steering wheel until the frontwheels are in the straight-ahead position
and engage the steering wheel lock.'yHave all vehicle occupants get out of the vehicle and ensure that they remain out#jside the immediate area in a safe place,
such as behind a guardrail.'yIf necessary, set up a warning triangle at an
appropriate distance.
Filling
the
tire
with
sealant
Safety
information DANGER
If the exhaust pipe is blocked or ventila#j
tion is insufficient, harmful exhaust gases can
enter into the vehicle. The exhaust gases con#j tain pollutants which are colorless and odor#j
less. In enclosed areas, exhaust gases can also
accumulate outside of the vehicle. There is
danger to life. Keep the exhaust pipe free and
ensure sufficient ventilation.'

Filling1.Shake the sealant container.2.Pull filling hose completely out of the cover
of the sealant container. Do not kink the
hose.3.Slide the sealant container into the holder
on the compressor housing, ensuring that
it engages audibly.4.Screw the filling hose of the sealant con#j tainer onto the tire valve of the nonworking
wheel.5.With the compressor switched off, insert
the plug into the power socket inside the
vehicle.6.With standby state switched on or the en#j gine running, switch on the compressor.
Let the compressor run for max. 10 minutes tofill the tire with sealant and achieve a tire infla#j
tion pressure of approx. 2.5 bar.
While the tire is being filled with sealant, the
tire inflation pressure may sporadically reach
approx. 5 bar. Do not switch off the compres#j
sor at this point.

Continuing
the
trip
Do not exceed the maximum permissible
speed of 50 mph/80 km/h.
Reinitialize the Flat Tire Monitor, refer to
page 307.
Reset the Tire Pressure Monitor, refer to
page 302.
Replace the nonworking tire and the sealant
container of the Mobility System promptly.
Snow
chains
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.
Information regarding suitable snow chains is
available from a dealer#ss service center or an#j other qualified service center or repair shop.
Use WARNING
With the mounting of snow chains on un#j
suitable tires, the snow chains can come into
contact with vehicle parts. There is a risk of ac#j
cidents or risk of property damage. Only mount
snow chains on tires that are designated by
their manufacturer as suitable for the use of
snow chains.'

Do not reset the Tire Pressure Monitor TPMafter mounting snow chains, as doing so mayresult in incorrect readings.
When driving with snow chains, briefly activate
Dynamic Traction Control DTC to optimize the
forward momentum.
Maximum
speed
with
snow
chains Do not exceed a speed of 30 mph/50 km/h
when using snow chains.
Rear
axle
steering
during
operation
with
snow
chains
General
information
In order to guarantee free running of the wheels when operating with snow chains, rearaxle steering of the integral active steering
must be switched off when snow chains are mounted.
Safety
information WARNING
When rear wheel steering is switched on
and snow chains are mounted, there can be contact between snow chains and the chassis.There is a risk of accidents or risk of propertydamage. With mounted snow chains, switchoff the rear wheel steering.'

The current tire temperatures may change
while driving or due to the external tempera#j
ture.

Measure
1.Reduce your speed and stop cautiously. Avoid sudden braking and steering maneu#jvers.2.Check whether the vehicle is fitted with
normal tires or run-flat tires.
Run-flat tires, refer to page 296, are la#j
beled with a circular symbol containing the letters RSC marked on the tire's sidewall.

1.Identify the damaged tire.
Check the tire inflation pressure in all four tires, for instance using the tire pressuregage 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.Seite 304MobilityWheels
