Mobile communication devices in the
vehicle
WARNING
Vehicle electronics and mobile phones
can influence one another. There is radiation
due to the transmission operations of mobile
phones. There is a risk of injury or risk of prop‐
erty damage. If possible, in the vehicle's inte‐
rior use only mobile phones with direct con‐
nections to an exterior antenna in order to
exclude mutual disturbance and deflect the ra‐
diation from the vehicle's interior.◀
Hydroplaning
On wet or slushy roads, a wedge of water can
form between the tires and road surface.
This phenomenon is referred to as hydroplan‐
ing. It is characterized by a partial or complete
loss of contact between the tires and the road
surface, ultimately undermining your ability to
steer and brake the vehicle.
Driving through water ATTENTION
When driving too quickly through too
deep water, water can enter into the engine
compartment, the electrical system or the
transmission. There is a risk of damage to
property. When driving through water, do not
exceed the maximum indicated water level and
the maximum speed for driving through wa‐
ter.◀
When driving through water, observe the fol‐
lowing:▷Drive through calm water only.▷Drive through water only if it is not deeper
than maximum 19.6 inches/50 cm.▷Drive through water no faster than walking
speed, up to 3 mph/5 km/h.Braking safely
Your vehicle is equipped with ABS as a stand‐ ard feature.
Perform an emergency stop in situations that
require such.
Steering is still responsive. You can still avoid
any obstacles with a minimum of steering ef‐
fort.
Pulsation of the brake pedal and sounds from
the hydraulic circuits indicate that ABS is in its
active mode.
In certain braking situations, the perforated
brake discs can emit functional noises. How‐
ever, this has no effect on the performance and
operational reliability of the brake.
Objects in the movement area around
pedals and floor area
WARNING
Objects in the driver's floor area can limit
the pedal distance or block a depressed pedal.
There is risk of an accident. Stow objects in
the vehicle such that they are secured and
cannot enter into the driver's floor area. Use
floor mats that are suitable for the vehicle and
can be safely attached to the floor. Do not use
loose floor mats and do not layer several floor
mats. Make sure that there is sufficient clear‐
ance for the pedals. Ensure that the floor mats
are securely fastened again after they were re‐
moved, e.g., for cleaning.◀
Driving in wet conditions When roads are wet, salted, or in heavy rain,
press brake pedal ever so gently every few
miles.
Ensure that this action does not endanger
other traffic.
The heat generated in this process helps dry
the brake discs and pads.
In this way braking efficiency will be available
when you need it.Seite 184Driving tipsThings to remember when driving184

LoadingVehicle features and options
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
Information WARNING
High gross weight can overheat the tires,
damage them, and cause a sudden drop in tire
inflation pressure. There is risk of an accident.
Pay attention to the permitted load capacity of
the tires and never exceed the permitted gross
weight.◀
WARNING
Loose objects or devices with a cable
connection to the vehicle, e.g., mobile phones,
can be thrown into the vehicle's interior while
driving, e.g.,in the event of an accident or dur‐
ing braking and evasive maneuvers. There is a
a risk of injury. Secure loose objects or devices
with a cable connection to the vehicle in the
vehicle's interior.◀
ATTENTION
Fluids in the cargo area can cause dam‐
age. There is a risk of damage to property.
Make sure that no fluids leak in the cargo
area.◀Determining the load limit1.Locate the following statement on your ve‐
hicle’s placard:▷The combined weight of occupants
and cargo should never exceed XXX kg
or YYY lbs. Otherwise, damage to the
vehicle and unstable driving situations
may result.2.Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.3.Subtract the combined weight of the driver
and passengers from XXX kilograms or
YYY pounds.4.The resulting figure equals the available
amount of cargo and luggage load ca‐
pacity.
For example, if the YYY amount equals
1,000 lbs and there will be four 150 lbs
passengers in your vehicle, the amount of
available cargo and luggage load capacity
is 400 lbs: 1,000 lbs minus 600 lbs =
400 lbs.5.Determine the combined weight of lug‐
gage and cargo being loaded on the vehi‐
cle. That weight may not safely exceed the
available cargo and luggage load capacity
calculated in Step 4.Seite 186Driving tipsLoading186

Load
The maximum load is the sum of the weight of
the occupants and the cargo.
The greater the weight of the occupants, the
less cargo that can be transported.
Stowing cargo
▷Cover sharp edges and corners on the
cargo.▷Heavy cargo: stow as far forward as possi‐
ble, directly behind and at the bottom of
the rear passenger seat backrests.▷Very heavy cargo: when the rear seat is not
occupied, secure each of the outer safety
belts in the opposite buckle.▷If necessary, fold down the rear backrests
to stow cargo.▷Do not stack cargo above the top edge of
the backrests.▷Use the cargo area partition net, refer to
page 174, to protect passengers. Make
sure that objects cannot penetrate the
cargo area partition net.Securing cargo
Lashing eyes in the cargo area
To secure the cargo there are four lashing
eyes in the cargo area.
Lashing eyes in the cargo area with
rails
To secure the cargo there are four movable
lashing eyes in the cargo area.
To slide the lashing eyes, press the button, ar‐
row 1. Make sure that the lashing eyes latch at
the new position.
The lashing eyes at the openings in the rails
can be removed.

Cargo net, FlexNetThe flexible cargo net is hooked into eyes and
secures the cargo in the cargo area. The stor‐
age net can be attached to the following eyes:▷Lashing eyes in the rails.▷Eyes on the cargo area wall.
The eyes are located on both sides of the
cargo area.
Securing cargo WARNING
Improperly stowed objects can shift and
be thrown into the vehicle's interior, e.g., in the
event of an accident or during braking and eva‐
sive maneuvers. Vehicle occupants can be hit
and injured. There is a risk of injury. Stow and
secure objects and cargo properly.◀
▷Smaller and lighter cargo: secure with
ratchet straps or with a cargo net or draw
straps.▷Larger and heavy cargo: secure with cargo
straps.
Secure cargo straps, cargo netting, retain‐
ing straps or draw straps on the lashing
eyes in the cargo area.
Roof-mounted luggage rack
Information
Installation only possible with roof rack.
Roof racks are available as special accessories.
Attachment to the rack Follow the installation instructions of the roof
rack.
Mounting
Be sure that adequate clearance is maintained
for tilting and opening the glass sunroof.
LoadingBecause roof-mounted luggage racks raise thevehicle's center of gravity when loaded, they
have a major effect on vehicle handling and
steering response.
Therefore, note the following when loading
and driving:▷Do not exceed the approved roof/axle
loads and the approved gross vehicle
weight.▷Be sure that adequate clearance is main‐
tained for tilting and opening the glass
sunroof.▷Distribute the roof load uniformly.▷The roof load should not extend past the
loading area.▷Always place the heaviest pieces on the
bottom.▷Secure the roof luggage firmly, for exam‐
ple, tie with ratchet straps.▷Do not let objects project into the opening
path of the tailgate.▷Drive smoothly. Avoid sudden acceleration
and braking maneuvers. Take corners gen‐
tly.Seite 188Driving tipsLoading188

shop. After rotating, check the tire pressure
and correct if needed.
Rotating the tires between the axes is not per‐
missible on vehicles with different tire sizes or
rim sizes on the front and rear axles.
Storage
Store wheels and tires in a cool, dry place with
as little exposure to light as possible.
Always protect tires against all contact with oil,
grease and fuels.
Do not exceed the maximum tire inflation pres‐
sure indicated on the side wall of the tire.
Run-flat tires
Label
RSC label on the tire sidewall.
The wheels consist of tires that are self-sup‐
porting, to a limited degree, and possibly spe‐
cial rims.
The support of the sidewall allows the tire to
remain drivable to a restricted degree in the
event of a tire inflation pressure loss.
Follow the instructions for continued driving
with a flat tire.
Changing run-flat tires
For your own safety, only use run-flat tires. No
spare tire is available in the case of a flat tire.
A dealer’s service center will be glad to answer
additional questions at any time.
Repairing a flat tire
Safety measures▷Park the vehicle as far away as possible
from passing traffic and on solid ground.▷Switch on the hazard warning system.▷Secure the vehicle against rolling away by
setting the parking brake.▷Turn the steering wheel until the front
wheels are in the straight-ahead position
and engage the steering wheel lock.▷Have all vehicle occupants get out of the
vehicle and ensure that they remain out‐
side the immediate area in a safe place,
such as behind a guardrail.▷If necessary, set up a warning triangle at an
appropriate distance.
Mobility System
The concept
With the Mobility System, minor tire damage
can be sealed temporarily to enable continued
travel. To accomplish this, sealant is pumped
into the tires, which seals the damage from the
inside.
The compressor can be used to check the tire
inflation pressure.
Information
▷Follow the instructions on using the Mobi‐
lity System found on the compressor and
sealant container.▷Use of the Mobility System may be ineffec‐
tive if the tire puncture measures approx.
1/8 in/4 mm or more.▷Contact a dealer’s service center or an‐
other qualified service center or repair
shop if the tire cannot be made drivable.▷If possible, do not remove foreign bodies
that have penetrated the tire.Seite 212MobilityWheels and tires212
