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.

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 178).
XObserve the additional display messages in the multifunction display.
XCheck the tires and, if necessary, follow the instructions for a flat tire
(Ypage 370).
XCheck the tire pressure (Ypage 394).
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.

This Operator's Manual describes all models
and all standard and optional equipment of
your vehicle available at the time of publica-
tion of the Operator's Manual. Country-spe-
cific 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.

Stowage areas
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, 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
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.
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 gross vehicle weight (GVW) is the vehicle
weight including fuel, vehicle tool kit, spare
wheel, installed accessories, vehicle occupants
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 (
Ypage 397).
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 (
Ypage 397).
Observe the notes on loading the vehicle
(
Ypage 397).
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).
RThe cargo compartment is the preferred place to carry objects.
RPosition heavy loads as far forwards as pos-
sible and as low down in the cargo compart-
ment as possible.
RThe load must not protrude above the upper
edge of the seat backrests.
RAlways place the load against the rear or frontseat 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 mate-
rials appropriate for the weight and size of theload.
RHook in the cargo net when loading.
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.
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 while
driving.
RStow and secure objects that are heavy,
hard, pointy, sharp-edged, fragile or too
large in the cargo compartment.
Observe the loading guidelines (
Ypage 329).

gory. The front-passenger front air bag could
deploy without cause, or may fail to deploy inthe 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.
Stowage nets are located in the front-passenger
footwell and on the back of the driver's and the
front-passenger seat.

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.

(
Ypage 330).

Important safety notes
GWARNING
If the rear bench seat/rear seat and seat
backrest are not engaged they could fold for-
wards, e.g. when braking suddenly or in the
event of an accident.
RThe vehicle occupant would 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/cargo com-
partment 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.
Make sure that the seat backrest and the seat
cushion are correctly engaged in position. To do
so, pull firmly on the seat backrest.
!Fold the seat cushion upwards before fold-
ing the rear bench seat forward. Otherwise,
the backrests may be damaged.
When the backrest is folded forwards, the
front seats should not be moved to their rear-
most position. Otherwise, the front seats and
the rear bench seat could be damaged.

!The backrest is heavy. Therefore, take care
when folding it down. Make sure that the head
restraints are pushed all the way in so that the backrests and seat cushions are not dam-
aged.

The left-hand and right-hand rear seat backrests
can be folded forwards separately to increase
the cargo compartment capacity.
Folding the rear bench seat forwards
If the driver's or front-passenger seat is set for a
larger person, it may not be possible to fold the rear bench seat forward. In this case, move the
front seats as far forward as possible.
