Solutions
hNThe yellow tire pressure monitor warning lamp (pressure loss/malfunction) is lit.
The tire pressure monitor has detected a loss of pressure in at least one of the tires.
GWARNING
Tire pressures that are too low pose the following hazards:
Rthey may burst, especially as the load and vehicle speed increase.
Rthey may wear excessively and/or unevenly, which may greatly impair tire trac-
tion.
Rthe driving characteristics, as well as steering and braking, may be greatly
impaired.
There is a risk of an accident.
XStop the vehicle without making any sudden steering or braking maneuvers. Pay
attention to the traffic conditions as you do so.
XSecure the vehicle against rolling away (Ypage 127).
XObserve the additional display messages in the multifunction display.
XCheck the tires and, if necessary, follow the instructions for a flat tire
(Ypage 249).
XCheck the tire pressure (Ypage 267).
XIf necessary, correct the tire pressure.
hN The yellow tire pressure monitor warning lamp (pressure loss/malfunction)
flashes for approximately one minute and then remains lit.
The tire pressure monitor is faulty.
GWARNING
The system is possibly unable to recognize or register low tire pressure.
There is a risk of an accident.
XObserve the additional display messages in the multifunction display.
XVisit a qualified specialist workshop immediately.

available. The mobile phone is always connec-
ted automatically after authorization. Further
information on using a mobile phone with the
multimedia system (see the Digital Operator's
Manual).
If the multimedia system does not detect your
mobile phone, this may be due to particular
security settings on your mobile phone (see the
manufacturer's operating instructions).
Only one mobile phone can be connected to themultimedia system at any one time.

Stowage areas
Loading guidelines
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Exhaust
gases can enter the vehicle interior if the
trunk lid is open when the engine is running,
especially if the vehicle is in motion. There is a
risk of poisoning.
Always switch off the engine before opening
the trunk lid. Never drive with the trunk lid
open.
GWARNING
If objects, luggage or loads are not secured or
not secured sufficiently, they could slip, tip
over or be flung around and thereby hit vehicle
occupants. There is a risk of injury, particu-
larly in the event of sudden braking or a sud-
den change in direction.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before the
journey.
GWARNING
The exhaust tail pipe and tail pipe trim can
become very hot. If you come into contact
with these parts of the vehicle, you could burn
yourself. There is a risk of injury.
Always be particularly careful around the
exhaust tail pipe and the tail pipe trim. Allow
these components to cool down before touch-
ing them.
!This vehicle is not designed to transport any
items on the trunk lid or to allow luggage car-
riers or equipment of any kind to be installed
to the trunk lid. Otherwise the vehicle and the
retractable hardtop could be damaged. The handling characteristics of a laden vehicle
are dependent on the distribution of the load
within the vehicle. For this reason, you should
observe the following notes when transporting a
load:
RNever exceed the maximum permissible
gross vehicle mass or the gross axle weight
rating for the vehicle (including occupants).
The values are specified on the vehicle iden-
tification plate on the B-pillar of the driver's
door.
RThe trunk is the preferred place to carry
objects.
RPosition heavy loads as far forwards as pos-
sible and as low down in the trunk as possible.
RThe load must not protrude above the upper
edge of the seat backrests.
RSecure the load with sufficiently strong and
wear-resistant tie-downs. Pad sharp edges for
protection.
Stowage spaces
Important safety notes
GWARNING
If objects in the passenger compartment are
stowed incorrectly, they can slide or be
thrown around and hit vehicle occupants. In
addition, cup holders, open stowage spaces
and mobile phone brackets cannot always
retain all objects they contain. There is a risk of injury, particularly in the event of sudden
braking or a sudden change in direction.
RAlways stow objects so that they cannot be
thrown around in such situations.
RAlways make sure that objects do not pro-
trude from stowage spaces, parcel nets or
stowage nets.
RClose the lockable stowage spaces before
starting a journey.
RAlways stow and secure heavy, hard, poin-
ted, sharp-edged, fragile or bulky objects in
the trunk.
Observe the loading guidelines (
Ypage 217).
