There is not enough brake fluid in the brake fluid reservoir.
GWARNING
The braking effect may be impaired.
There is a risk of an accident.
XPull over and stop the vehicle safely as soon as possible, paying
attention to road and traffic conditions. Do not continue driving
under any circumstances.
XSecure the vehicle against rolling away (Ypage 153).
XDo not add brake fluid. Adding more will not remedy the
malfunction.
XConsult a qualified specialist workshop.
XObserve the additional display messages in the multifunction
display.

The yellow ABS warning
lamp is lit while the
engine is running.
ABS (Anti-lock Braking System) is deactivated due to a
malfunction. Therefore, BAS (Brake Assist), COLLISION
PREVENTION ASSIST, COLLISION PREVENTION ASSIST PLUS,
ESP®(Electronic Stability Program), the HOLD function and hill
start assist, for example, are also deactivated.
ATTENTION ASSIST is deactivated.
GWARNING
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
affected. 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.
XObserve the additional display messages in the multifunction
display.
XDrive on carefully.
XVisit a qualified specialist workshop.
If the ABS control unit is faulty, there is also a possibility that other
systems, such as the navigation system or the automatic
transmission, will not be available.

affected. The braking distance in an emergency braking situation
can increase.
If ESP®is not operational, ESP®is unable to stabilize the vehicle.
There is a risk of an accident.
XCarefully drive a suitable distance, making slight steering
movements at a speed above 12 mph (20 km/h).

Solutions
\r
The 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 153).
XLeave the vehicle and keep a safe distance from the vehicle until
the engine has cooled down.
XCheck the coolant level and add coolant (Ypage 283). Observe
the warning notes.
XIf you need to add coolant more often than usual, have the
engine coolant 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
under 248‡(120 †). Otherwise, the engine could be damaged.
XDrive to the nearest qualified specialist workshop.
XAvoid subjecting the engine to heavy loads, e.g. driving in
mountainous terrain, and stop-and-go traffic.

GWARNING
The engine is not being cooled sufficiently and may be damaged.
Do not drive whenyour engine is overheated. This can cause some
fluids which may have leaked into the engine compartment to
catch fire.
Vapor from the overheated engine can also cause serious burns
which can occur just by opening the hood.
There is a risk of injury.

Useful information
iThis Operator's Manual describes all
models and all standard and optional
equipment 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.
iRead the information on qualified
specialist workshops: (Ypage 25).
Loading guidelines
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,
particularly in the eventofsudden braking or
a suddenchange 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
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.
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 weight or the gross axle
weight rating of the vehicle (including
occupants). The values are specified on the
vehicle identification 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
possible 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 against the rear or
front seat backrests. Make sure that the
seat backrests are securely locked into
place.
RAlways place the load behind unoccupied
seats if possible.
RUse the cargo tie down rings and the parcel
nets to transport loads and luggage.
RUse cargo tie-down rings and fastening
materials appropriate for the weight and
size of the load.
RSecure the load with sufficiently strong and
wear-resistant tie-downs. pad sharp edges
for protection.
Stowage areas
Stowage space
Important safety notes
GWARNING
If you do not correctly store objects in the
vehicle interior, they can slip or be flung
around, thus striking vehicle occupants.
There is a risk of injury, especially when
braking or abruptly changing directions.

Important safety notes
GWARNING
If the rear bench seat/rear seat and seat
backrest are not engaged they could fold
forwards, e.g. when braking suddenly or in the
event of an accident.
RThe vehicle occupantwould thereby be
pushed into the seat belt by the rear bench
seat/rear seat or by the seat backrest.The
seat belt can no longer offer the intended
level of protection and could even cause
injuries.
RObjects or loads in the trunk cannot be
restrained by the seat backrest.
There is an increased risk of injury.
Before every trip, make sure that the seat
backrests and the rear bench seat/rear seat
are engaged.

Features
Cup holder
Important safety notes
GWARNING
The cup holder cannot hold a container secure
whilst traveling. If you use a cup holder whilst
traveling, the container may be flung around
and liquid may be spilled. The vehicle
occupants may come into contact with the
liquid and if it is hot, they may be scalded. You
may be distracted from the traffic conditions
and you could lose control of the vehicle.
There is a risk of an accident and injury.
Only use the cup holder when the vehicle is
stationary. Only use the cup holder for
containers of the right size. Always close the
container, particularly if the liquid is hot.
GWARNING
If you do not correctly store objects in the
vehicle interior, they can slip or be flung
around, thus striking vehicle occupants.
There is a risk of injury, especially when
braking or abruptly changing directions.
RAlways store objects so that they cannot be
flung around in these or in similar
