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

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 subjecting the engine to heavy loads, e.g. driving in moun-
tainous terrain, and stop-and-go traffic.

Possible causes/consequences and P Solutions

Tires Problem
Possible causes/consequences and P Solutions
w
The 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.
G WARNING
With tire pressures which are too low, there is a risk of the fol-
lowing 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 189).X
Observe the additional display messages in the multifunction
display. X
Check the tires and, if necessary, follow the instructions for a
flat tire ( Y
page 387). X
Check the tire pressure ( Y
page 412).X
If necessary, correct the tire pressure.
w
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.
G WARNING
The system is possibly unable to recognize or register low tire
pressure.
There is a risk of an accident. X
Observe the additional display messages in the multifunction
display. X
Visit a qualified specialist workshop.338

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.
i Read the information on qualified special-
ist workshops ( Y
page 29).
Stowage areas
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. If the tailgate
is open when the engine is running, particu-
larly if the vehicle is moving, exhaust fumes
could enter the passenger compartment.
There is a risk of poisoning.
Turn off the engine before opening the tail-
gate. Never drive with the tailgate 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 gross vehicle weight (GVW) is the vehicle
weight including fuel, vehicle tool kit, spare
wheel, installed accessories, vehicle occu-
pants and luggage/cargo.
Do not exceed the load limit or permitted
gross vehicle weight rating (GVWR) for your
vehicle. The gross load limit and the GVWR
are specified on the vehicle identification
plate on the B-pillar of the driver's door
( Y
page 416).
The load must also be distributed so that the
weight on each axle never exceeds the gross
axle weight rating (GAWR) for the front and
rear axles. The specifications for GVWR and
GAWR are on the vehicle identification plate
on the B-pillar of the driver's door
( Y
page 416).
Observe the notes on loading the vehicle
( Y
page 416).
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). R
The cargo compartment is the preferred
place to carry objects. R
Position heavy loads as far forwards as pos-
sible and as low down in the cargo com-
partment as possible. 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.340
Stowage areas
Stowage and features

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.
Stowage spaces
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 while
driving. R
Stow and secure objects that are heavy,
hard, pointy, sharp-edged, fragile or too
large in the cargo compartment.
Observe the loading guidelines ( Y
page 340).

Stowage net
G WARNING
Vehicles with the Occupant Classification
System (OCS):
If the gross weight of the objects in the stow-
age net on the back of the front-passenger
seat is greater than 4.4 lb (2 kg), OCS cannot
correctly assess the occupant's weight cate-
gory. The front-passenger front air bag could
deploy without cause, or may fail to deploy in
the event of an accident. This poses an
increased risk of injury or even fatal injury.
Always observe the permissible gross weight
of 4.4 lb (2 kg). Stow and secure heavy
objects in the cargo compartment.

page 341).
Through-loading facility in the rear If objects or loads are not secured when being
transported in the through-loading facility,
they could slip or be thrown around and
thereby hit vehicle occupants.
Observe the loading guidelines ( Y
page 340)
and the safety notes regarding stowage
spaces ( Y
page 341).
The through-loading facility is opened from
the cargo compartment. X
Release the seat backrests in the second
row of seats and tilt them in the cargo/load
position ( Y
page 113). X
Fold down the rear seat armrest. Stowage areas 343
Stowage and features Z

Cargo compartment
There are four cargo tie-down rings C in the
cargo compartment.
Bag hook
G WARNING
The bag hooks cannot restrain heavy objects
or items of luggage. Objects or items of lug-
gage could be flung around and thereby hit
vehicle occupants when braking or abruptly
changing directions. There is a risk of injury.
Only hang light objects on the bag hooks.
Never hang hard, sharp-edged or fragile
objects on the bag hooks.
! The bag hook can bear a maximum load of
6.6lbs (3kg ) and should not be used to
secure a load.
There is a bag hook in the cargo compartment
on the right-hand side. X
Press bag hook marking C .X
Turn bag hook C until it engages. Cargo compartment cover
Important safety notes
G WARNING
On its own, the cargo compartment cover
cannot secure or restrain heavy objects,
items of luggage and heavy loads. You could
be hit by an unsecured load during sudden
changes in direction, braking or in the event of
an accident. There is an increased risk of
injury or even fatal injury.
Alwa ys store objects so that they cannot be
flung aroun d. Secure objects, luggage or
loads against slipping or tipping over, e.g. by
using tie downs, even if you are using the
cargo compartment cover.
! When loading the vehicle, make sure that
you do not stack the load in the cargo com-
partment higher than the lower edge of the
side windows. Do not place heavy objects
on top of the cargo compartment cover.
The cargo compartment cover may be instal-
led behind the 2nd or 3rd row of seats.
