▷While the driver's seat belt is unbuckled, if
the driver's door is open and the low
beams are switched off.
When the ignition is switched off, by opening
or closing the driver's door or unbuckling the
driver's seat belt, the radio ready state remains
active.
Radio ready state
Activate radio ready state:
▷When the engine is running: press the
Start/Stop button.
Some electronic systems/power consumers
remain ready for operation.
The radio ready state switches off automati‐
cally:
▷After approx. 8 minutes.▷When the vehicle is locked using the cen‐
tral locking system.▷Shortly before the battery is discharged
completely, so that the engine can still be
started.
Starting the engine
Hints Enclosed areas
Do not let the engine run in enclosed
areas; otherwise, breathing of exhaust fumes may lead to loss of consciousness and death.
The exhaust gases contain carbon monoxide,
an odorless and colorless but highly toxic
gas.◀
Unattended vehicle
Do not leave the vehicle unattended with
the engine running; doing so poses a risk of
danger.
Before leaving the vehicle with the engine run‐
ning, set the parking brake and place the trans‐
mission in position P or neutral to prevent the
vehicle from moving.◀
Repeated starting in quick succession
Avoid repeated unsuccessful attempts to
start the vehicle or starting the vehicle several
times in quick succession. Otherwise, the fuel
is not burned or is inadequately burned, posing
a risk of overheating and damage to the cata‐
lytic converter.◀
Do not wait for the engine to warm-up while
the vehicle remains stationary. Start driving at
moderate engine speeds.
Diesel engine
If the engine is cold and temperatures are be‐
low approx. 32 ℉/0 ℃, the start process may
be delayed somewhat due to automatic pre‐
heating.
A Check Control message is displayed.
Manual transmission
Starting the engine1.Depress the brake pedal.2.Press on the clutch pedal and shift to neu‐
tral.3.Press the Start/Stop button.
The ignition is activated automatically for a
certain time and is stopped as soon as the en‐
gine starts.
Automatic transmission

certain time and is stopped as soon as the en‐
gine starts.

Adhere to water depth and speed limita‐
tions
Do not exceed this water depth and walking
speed; otherwise, the vehicle's engine, the
electrical systems and the transmission may
be damaged.◀
Braking safely
Your vehicle is equipped with ABS as a stand‐ ard feature.
Applying the brakes fully is the most effective
way of braking in situations when this is neces‐
sary.
The vehicle maintains steering responsive‐
ness. You can still avoid any obstacles with a
minimum of steering effort.
Pulsation of the brake pedal and sounds from
the hydraulic circuits indicate that ABS is in its
active mode.
Objects in the area around the pedals No objects in the area around the pedals
Keep floor mats, carpets, and any other
objects out of the area of motion of the pedals;
otherwise, the function of the pedals could be
impeded while driving
Do not place additional floor mats over existing
mats or other objects.
Only use floor mats that have been approved
for the vehicle and can be properly fixed in
place.
Ensure that the floor mats are securely fas‐
tened again after they were removed for clean‐
ing, for example.◀
Driving in wet conditions When roads are wet coated with road salt or
there is heavy rain, briefly exert gentle pres‐
sure 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, re‐
sulting in a reduction in the brake system effi‐
ciency.
You can increase the engine's braking effect
by shifting down, going all the way to first gear,
if necessary.
Avoid load on the brakes
Avoid placing excessive load on the
brake system. Light but consistent brake pres‐
sure can lead to high temperatures, brake wear
and possibly 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 un‐
available with the engine stopped.◀
Brake disc corrosion
The corrosion on the brake discs and the con‐
tamination 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.
