;NThe yellow Check Engine warning lamp lights up while the engine is running.
There may be a malfunction, for example:
Rin the engine management
Rin the fuel injection system
Rin the exhaust system
Rin the ignition system (for vehicles with gasoline engines)
Rin the fuel system
The emission limit values may be exceeded and the engine may be in emergency
mode.
XVisit a qualified specialist workshop immediately.
In some states, you must immediately visit a qualified specialist workshop as soon as the yellow Check Engine warning lamp lights up. This is due to the legal require-
ments in effect in these states. If in doubt, check whether such legal regulations
apply in the state in which you are currently driving.
8N The yellow reserve fuel warning lamp lights up while the engine is running.
The fuel level has dropped into the reserve range.
XRefuel at the nearest gas station.
8N The yellow reserve fuel warning lamp flashes while the vehicle is in motion.
In addition, the ;Check Engine warning lamp may light up.
The fuel system pressure is too low. The fuel filler cap is not closed correctly or the
fuel system is leaking.
XCheck that the fuel filler cap is correctly closed.

?NThe red coolant warning lamp comes on while the engine is running.
The coolant level is too low.
If the coolant level is correct, the airflow to the engine radiator may be blocked or
the electric engine radiator fan may be malfunctioning.
The coolant is too hot and the engine is no longer being cooled sufficiently.
XObserve the additional display messages in the multifunction display.
XPull over and stop the vehicle safely and switch off the engine, paying attention
to road and traffic conditions.
XSecure the vehicle against rolling away (Ypage 177).
XLeave the vehicle and keep a safe distance from the vehicle until the engine has cooled down.
XCheck the coolant level and add coolant, observing the warning notes
(Ypage 333).
XIf you have to add coolant frequently, have the engine cooling system checked.
XMake sure that the air supply to the engine radiator is not blocked, e.g. by snow,
slush or ice.
XDo not start the engine again until the coolant temperature is below 248 ‡
(120 †). Otherwise, the engine could be damaged.
XDrive to the nearest qualified specialist workshop.
XAvoid heavy loads on the engine as you do so, e.g. driving in mountainous terrain
and stop-start traffic.
?N The red coolant warning lamp comes on while the engine is running. A warning
tone also sounds.
The coolant temperature has exceeded 248 ‡(120 †). The airflow to the engine
radiator may be blocked or the coolant level may be too low.
GWARNING
The engine is not being cooled sufficiently and may be damaged.
Do not drive when your engine is overheated. This can cause some fluids which
may have leaked into the engine compartment to catch fire.
Steam from the overheated engine can also cause serious burns which can occur
just by opening the hood.
There is a risk of injury.

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.
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.
RAlways place the load behind unoccupied
seats if possible.
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, cupholders, 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 308).

Cigarette lighter
GWARNING
You can burn yourself if you touch the hot
heating element or the socket of the cigarette lighter.
In addition, flammable materials can ignite if:
Rthe hot cigarette lighter falls
Ra child holds the hot cigarette lighter to
objects, for example
There is a risk of fire and injury.
Always hold the cigarette lighter by the knob.
Always make sure that the cigarette lighter is
out of reach of children. Never leave children
unsupervised in the vehicle.
Your attention must always be focused on the
traffic conditions. Only use the cigarette lighter when road and traffic conditions permit.
Example
XTurn the SmartKey to position 2in the ignition
lock (Ypage 146).
XTo open: open the stowage compartment
(Ypage 309).
XPress in cigarette lighter ;.
Cigarette lighter ;will pop out automatically
when the heating element is red-hot.
XTo close: push cover :of the stowage com-
partment closed.
12 V sockets
General notes
XTurn the SmartKey to position 1in the ignition
lock (Ypage 146).
The sockets can be used for accessories with a maximum draw of 180 W (15 A). Accessories
include such items as chargers for mobile
phones.
If you use the sockets for long periods when the
engine is switched off, the battery may dis-
charge.
An emergency cut-out ensures that the on-
board voltage does not drop too low. If the on-
board voltage is too low, the power to the sock-
ets is automatically cut. This ensures that there is sufficient power to start the engine.
If you have connected a device to the 12 V
socket, leave the cover of the stowage com-
partment open. This prevents the cover from
being blocked.
Socket in the front-compartment center
console
XTo open: open the stowage compartment
(Ypage 309).
XLift up the cover of the socket.
XTo close: push the cover of the stowage com-
partment closed.
Socket in the rear-compartment center
console
XPull the cover out by the top of its handle
edge.
