Possible causes/consequences and P Solutions
Check Tire Pres‐
sure Soon Canada only:
The tire pressure loss warning system has detected a significant
loss in pressure.
A warning tone also sounds.
Possible causes: R
you have changed the positions of the wheels and tires or instal-
led new wheels and tires. R
the tire pressure in one or more tires has dropped
G WARNING
Tire pressures that are too low pose the following hazards: R
they may burst, especially as the load and vehicle speed
increase. R
they may wear excessively and/or unevenly, which may greatly
impair tire traction. R
the driving characteristics, as well as steering and braking, may
be greatly impaired.
There is a risk of an accident. X
Stop the vehicle without making any sudden steering or braking
maneuvers. Pay attention to the traffic conditions as you do so. X
Secure the vehicle against rolling away ( Y
page 169).X
Check the tires and, if necessary, follow the instructions for a
flat tire ( Y
page 310). X
Check the tire pressures and, if necessary, correct the tire pres-
sure. X
Restart the tire pressure loss warning system when the tire
pressure is correct ( Y
page 336).
Check Tire Pres‐
sure Then Restart
Run Flat Indicator Canada only:
The tire pressure loss warning system generated a display mes-
sage and has not been restarted since. X
Set the correct tire pressure in all four tires. X
Restart the tire pressure loss warning system ( Y

The yellow ABS warning
lamp is lit while the
engine is running. ABS (Anti-lock Braking System) is deactivated due to a malfunc-
tion. Therefore, BAS (Brake Assist), COLLISION PREVENTION
ASSIST PLUS, ESP ®
(Electronic Stability Program), the HOLD func-
tion and hill start assist are also deactivated, for example.
ATTENTION ASSIST is deactivated.
G WARNING
The brake system continues to function normally, but without the
functions listed above. The wheels could therefore lock if you
brake hard, for example.
The steerability and braking characteristics may be severely affec-
ted. The braking distance in an emergency braking situation can
increase.
If ESP ®
is not operational, ESP ®
is unable to stabilize the vehicle.
There is an increased risk of skidding and an accident. X
Observe the additional display messages in the multifunction
display. X
Drive on carefully. X
Visit a qualified specialist workshop immediately.
If the ABS control unit is faulty, there is also a possibility that other
systems, such as the navigation system or the automatic trans-
mission, will not be available.Warning and indicator lamps in the instrument cluster 261

bution), the HOLD function and hill start assist are also deactiva-
ted, for example.
Possible causes are: R
Self-diagnosis is not yet complete. R
The on-board voltage may be insufficient.
ATTENTION ASSIST is deactivated.
G WARNING
The brake system continues to function normally, but without the

increase.
If ESP ®
is not operational, ESP ®
is unable to stabilize the vehicle.
There is a risk of an accident. X
Carefully drive a suitable distance, making slight steering move-
ments at a speed above 12 mph (20 km/h).
The functions mentioned above are available again when the
warning lamp goes out.

Leave the vehicle and keep a safe distance from the vehicle until
the engine has cooled down. X
Check the coolant level and add coolant, observing the warning
notes ( Y
page 299). X
If you have to add coolant frequently, have the engine cooling
system checked. X
Make sure that the air supply to the engine radiator is not
blocked, e.g. by snow, slush or ice. X
At coolant temperatures below 248 ‡ (120 †), drive to the
nearest qualified specialist workshop. X
Avoid heavy loads on the engine as you do so, e.g. driving in
mountainous terrain and stop-start traffic.

Useful information
i This Operator's Manual describes all
models and all standard and optional equip-
ment of your vehicle available at the time of
publication of the Operator's Manual.
Country-specific differences are possible.
Please note that your vehicle may not be
equipped with all features described. This
also applies to safety-related systems and
functions.

Loading guidelines
G WARNING
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.
G WARNING
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.
G WARNING
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.
The handling characteristics of a laden vehi-
cle are dependent on the distribution of the
load within the vehicle. For this reason, you
should observe the following notes when
transporting a load: R
Never 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
identification plate on the B-pillar of the
driver's door. R
The trunk is the preferred place to carry
objects. R
Position heavy loads as far forwards as pos-
sible and as low down in the trunk as pos-
sible. R
The load must not protrude above the
upper edge of the seat backrests. R
Always place the load against the rear or
front seat backrests. Make sure that the
seat backrests are securely locked into
place. R
Always place the load behind unoccupied
seats if possible. R
Use the cargo tie-down rings and the parcel
nets to transport loads and luggage. R
Use cargo tie-down rings and fastening
materials appropriate for the weight and
size of the load. R
Secure the load with sufficiently strong and
wear-resistant tie-downs. Pad sharp edges
for protection.272

Important safety notes
G WARNING
If objects in the passenger compartment are
stowed incorrectly, they can slide or be
thrown around and hit vehicle occupants.
There is a risk of injury, particularly in the
event of sudden braking or a sudden change
in direction. R
Always stow objects so that they cannot be
thrown around in such situations. R
Always make sure that objects do not pro-
trude from stowage spaces, parcel nets or
stowage nets. R
Close the lockable stowage spaces before
starting a journey. R
Always stow and secure heavy, hard, poin-
ted, sharp-edged, fragile or bulky objects in
the trunk.
Observe the loading guidelines ( Y
