Opening and closing

Before leaving the car with the engine running,
set
the parking brake and place the transmission
in position P or neutral to prevent the car from
moving.◀
Frequent starting in quick succession
Avoid repeated futile attempts at starting
the car and avoid starting the car frequently in
quick succession. Otherwise, the fuel is not
burned or is inadequately burned, and there is
the danger of overheating and damaging the
catalytic converter.◀
Do not wait for the engine to warm up while the
vehicle remains stationary. Start driving at mod‐
erate engine speeds.
Starting the engine
Press on the brake pedal and
press the Start/Stop button.
The engine is cranked until it
starts.
Engine stop
General information Take the remote control with you
Take the remote control with you when
leaving the vehicle so that children, for example,
cannot operate the windows and injure them‐
selves.◀
Set the parking brake and further secure
the vehicle as required
Set the parking brake firmly when parking; oth‐
erwise, the vehicle could roll. On steep upward
and downward inclines, further secure the vehi‐
cle, for example, by turning the steering wheel in
the direction of the curb. ◀
Before driving into a car wash
In order for the vehicle to be able to roll into a car
wash, heed the information regarding Washing
in automatic car washes, refer to page 271. Switching off the engine
1.
Engage transmission position P with the ve‐
hicle stopped.
2. Press the Start/Stop button.
The engine is switched off.
The radio ready state is switched on.
3. Set the parking brake.
Parking brake
The concept
The

parking brake is used to prevent the vehicle
from rolling when it is parked.
▷ Engine switched off: the parking brake acts
on the rear wheels.
▷ Engine running: the parking brake acts on
the disc brakes of the front and rear wheels
via the hydraulic brake system.
The parking brake can be set manually or auto‐
matically:
▷ Manual: by pulling and pushing the switch.
▷ Automatic: by activating Automatic Hold. Setting
Pull the switch.
The LED lights up.
The indicator lamp lights up in red. The
parking brake is set.

Driving

Driving in wet conditions
When
roads are wet or there is heavy rain, briefly
exert gentle pressure on the brake pedal every
few miles.
Ensure that this action does not endanger other
road users.
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.
Hills
Drive long or steep downhill gradients in the gear
in which the least braking is required. Otherwise,
the brake system may overheat, resulting in a
reduction in the brake system efficiency.
You can increase the engine's braking effect by
shifting down in the manual mode of the auto‐
matic transmission, refer to page 72.
Avoid load on the brakes
Avoid placing excessive load on the brake
system. Light but consistent brake pressure can
lead to high temperatures, brake wear and pos‐
sibly even brake failure.◀
Do not drive in neutral
Do not drive in neutral or with the engine
stopped, as doing so disables engine braking. In
addition, steering and brake assist is unavailable
with the engine stopped.◀
Brake disc corrosion
Corrosion on the brake discs and contamination
on the brake pads are furthered by:
▷ Low mileage.
▷ Extended periods when the vehicle is not
used at all.
▷ Infrequent use of the brakes.
Corrosion occurs when the minimum pressure
that must be exerted by the pads during brake
applications to clean the discs is not reached.
Should corrosion form on the brake discs, the
brakes will tend to respond with a pulsating ef‐
fect that generally cannot be corrected. Condensation under the parked vehicle
When
using the automatic climate control, con‐
densation water develops that exits underneath
the vehicle.
Therefore, traces of condensed water under the
vehicle are normal.
Loading
Overloading the vehicle
To avoid exceeding the approved carrying
capacity of the tires, never overload the vehicle.
Overloading can lead to overheating and in‐
creases the rate at which damage develops in‐
side the tires. This could result in a sudden loss
of tire inflation pressure.◀
No fluids in the trunk
Make sure that fluids do not leak into the
trunk; otherwise, the vehicle may be damaged.◀
Determining the load limit 1.
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 ve‐
hicle

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. Seite 146
