54 Getting started
Parking and locking
You have now completed your first drive.
You have properly stopped and parked
your vehicle. End your drive as follows.
Parking brake
Warning!G
Vehicles with manual transmission:
Wait until the vehicle is stationary before
removing the SmartKey from the starter
switch. The vehicle cannot be steered when
the SmartKey is removed.
Warning!G
With the engine not running, there is no
power assistance for the brake and steering
system. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the
vehicle.
Warning!G
Do not park this vehicle in areas where
combustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system, as these materials could be
ignited and cause a vehicle fire.
To reduce the risk of personal injury, or
damage to the vehicle or the vehicle
drivetrain, as a result of vehicle movement,
always do the following before turning off
the engine and leaving the vehicle:

Keep right foot on brake pedal.

Manual transmission: Move the gear-
shift lever into neutral position (no gear
is selected).

Firmly depress parking brake pedal.

Manual transmission: Move the gear-
shift lever into first or reverse gear.

Automatic transmission*: Move the
gear selector lever to positionP.

Slowly release brake pedal.

When parked on an incline, always turn
the front wheels towards the road curb.

Turn the SmartKey in the starter switch
to position0 and remove.

Take the SmartKey with you and lock
the vehicle when leaving, which could
endanger other road users when you en-
gage the parking brake.
Warning!G
Do not engage the parking brake while the
vehicle is in motion. Doing so can cause the
rear wheels to lock up. You could lose con-
trol of the vehicle and cause an accident. In
addition, the vehicle’s brake lights do not
light up when the parking brake is engaged,
which could endanger other road users.

263 Operation
Driving instructions
Refer to the description of the Brake Assist
System (BAS) (
page 84).
Brake pad wear or a leak in the system may
be the reason for low brake fluid level in
the reservoir.
The brake fluid level in the reservoir may
be too low if the brake warning lamp in the
instrument cluster comes on and an
acoustic warning sounds although the
parking brake is released (
page 324).
Observe additional messages in the multi-
function display that may appear
(
page 344).
Have the brake system inspected
immediately. Contact an authorized
Mercedes-Benz Center.All checks and service work on the brake
system should be carried out by qualified
technicians only. Contact an authorized
Mercedes-Benz Center.
Only install brake pads and brake fluid
recommended by Mercedes-Benz.
After hard braking, it is advisable to drive
on for some time, rather than immediately
park, so that the air stream will cool down
the brakes faster.
Driving off
Apply the brakes to test them briefly after
driving off. Perform this procedure only
when the road is clear of other traffic.
Warm up the engine smoothly. Do not
place full load on the engine until the
operating temperature has been reached.
Warning!G
Make sure not to endanger any other road
users when carrying out these braking ma-
neuvers.
Warning!G
If other than recommended brake pads are
installed, or other than recommended brake
fluid is used, the braking properties of the
vehicle can be degraded to an extent that
safe braking is substantially impaired. This
could result in an accident.
!When driving down long and steep grades,
relieve the load on the brakes by shifting into a
lower gear to use the engine’s braking power.
This helps prevent overheating of the brakes and
reduces brake pad wear.
!When starting off on a slippery surface, do
not allow a drive wheel to spin for an extended
period with the ESP
® switched off. Doing so may
cause serious damage to the drivetrain which is
not covered by the Mercedes-Benz Limited
Warranty.
!Simultaneously depressing the accelerator
pedal and applying the brake reduces engine
performance and causes premature brake and
drivetrain wear.
