ABS (Anti-lock Brake System) is deactivated due to a malfunction.
Therefore, BAS

(Brake Assist), ESP ®
(Electronic Stability Program),
EBD (electronic brake force distribution) and 4ETS are also
deactivated.
The brake system continues to function normally, but without the
functions listed above. The wheels could therefore lock if you
brake hard, for example.

navigation system or the automatic transmission, may also be
unavailable. !

WARNING
Each tire, including the spare (if provided), should be checked at least every two weeks when
cold and inflated to the pressure recommended by the vehicle manufacturer on the Tire and
Loading Information placard on the driver's door B-pillar or, if available, the tire pressure label
on

the inside of the fuel filler flap. If your vehicle has tires of a different size than the size indicated
on the Tire and Loading Information placard or the tire pressure label, you should determine the
proper tire pressure for those tires.
As an added safety feature, your vehicle has been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires are
significantly underinflated. Accordingly, when the low tire pressure telltale illuminates, you should
stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving
on a significantly underinflated tire causes the tire to overheat and can lead to tire failure.
Underinflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling
and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance,
and it is the driver's responsibility to maintain correct tire pressure, even if underinflation has
not reached the level to trigger illumination of the TPMS low tire pressure telltale.
USA only:
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the
system is not operating properly. The TPMS malfunction indicator is combined with the low tire
pressure telltale. When the system detects a malfunction, the telltale will flash for approximately
1 minute and then remain continuously illuminated. This sequence will be repeated every time Warning and indicator lamps in the instrument cluster

the vehicle is started as long as the malfunction exists. When the malfunction indicator is
illuminated, the system may not be able to detect or signal low tire pressure as intended.
TPMS
malfunctions
may occur for a variety of reasons, including the installation of incompatible
replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels
on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to
continue to function properly. 186

Useful information
i This 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.
i Please read the information on qualified
specialist workshops (Y page 20). Loading guidelines
G
WARNING
Always
fasten items being carried as securely
as possible using cargo tie-down rings and
fastening materials

appropriate for the weight
and size of the load.
In an accident, during hard braking or sudden
maneuvers, loose items will be thrown around
inside the vehicle. This can cause injury to
vehicle occupants unless the items are
securely fastened in the vehicle.
To help avoid personal injury during a collision
or sudden maneuver, exercise care when
transporting cargo. Do not pile luggage or
cargo higher than the seat backrests.
Never drive a vehicle with the tailgate open.
Deadly carbon monoxide (CO) gases may
enter vehicle interior resulting in
unconsciousness and death.
The handling characteristics of a laden
vehicle are dependent on the distribution of
the load within the vehicle. You should
therefore load your vehicle as shown in the
illustrations. The
gross vehicle weight (GVW) is the vehicle
weight including fuel, vehicle tool kit, spare
wheel, installed accessories, vehicle
occupants and luggage/cargo.
The gross load limit and the gross vehicle
weight rating (GVWR) for your vehicle must
never be exceeded. 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 271).
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 271).
Further information can be found in the
"Loading the vehicle" section ( Y page 252).
Observe the following notes when
transporting a load:
R position heavy loads as far forwards as
possible and as low down in the cargo
compartment as possible.
i Transport loads when possible in the
cargo compartment. You should only use
the cargo compartment enlargement if the
load does not fit in the cargo compartment.
R always place the load against the front or
rear seat backrests.188

compartment.
Securing cargo
Important safety notes G
WARNING
Distribute the load on the cargo tie down rings
evenly.
Otherwise, vehicle occupants could be
injured by

objects being thrown around if you:
R brake sharply
R change direction suddenly
R are involved in an accident
Please observe the loading guidelines.
Observe the following notes on securing
loads:
R secure the load using the cargo tie down
rings.
R do not use elastic straps or nets to secure
a load, as these are only intended as an
anti-slip protection for light loads.
R do not route tie downs across sharp edges
or corners.
R pad sharp edges for protection.
R only use tie downs that have been checked
in accordance with applicable standards,
e.g. lashing nets or lashing straps.
R fill the spaces between the load and the
cargo compartment walls and the wheel
mountings in a form-locking way. Only use
dimensionally stable transportation aids
for this, such as chocks, wooden fixings or
padding.
Cargo tie down rings in the cargo
compartment There are four cargo tie down rings in the
cargo compartment mounted at the sides. Cargo compartment cover
Important safety notes !
When loading

the vehicle, make sure that
you do not stack the load in the cargo
compartment 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 is located
behind the rear bench seat backrest.

WARNING
When leaving the vehicle, always remove the
SmartKey from the ignition lock. Always take
the SmartKey with you and lock the vehicle.
Do not leave children unattended in the
vehicle, even if they are secured in a child
restraint system, or with access to an
unlocked vehicle. A child's unsupervised
access to

a vehicle could result in an accident
and/or serious personal injury. The children
could:
R injure themselves on parts of the vehicle
R be seriously or fatally injured through
excessive exposure to extreme heat or cold
R injure themselves or cause an accident with
vehicle equipment that can be operated
even if the SmartKey is removed from the
ignition lock or removed from the vehicle,
such as seat adjustment, steering wheel
adjustment, or the memory function
If children open a door, they could injure other
persons or get out of the vehicle and injure
themselves or be injured by following traffic.
Do not expose the child restraint system to
direct sunlight. The child restraint system's
metal parts, for example, could become very
hot, and the child could be burned on these
parts. G
WARNING
Never touch the heating element or sides of
the lighter; they are extremely hot. Hold the
knob only. Features
