Driving safety systems
The SBC brake system is automatically ac-
tivated when you:

unlock the vehicle with the key or the
KEYLESS-GO* card


open the driver’s or passenger door


turn the key in the starter switch to
position1


in vehicles with KEYLESS-GO*, press
start/stop button on selector lever
once


depress the brake pedal


release the parking brake
Warning!
G
The SBC brake system requires electrical
power to operate.
A malfunction in the vehicle’s power supply
or electrical system may impair brake sys-
tem operation and switch it into its emer-
gency operation mode. In such a case, the
red brake warning lamp (
page 253) and
the warning messages (
page 265) light up
while driving. To brake, the driver must then
apply significantly greater brake pedal pres-
sure and depress the pedal much further to
obtain the expected braking effect. If neces-
sary, apply full pressure to the brake pedal.
Brakes are only applied to the front wheels.
Stopping distance is increased!
If there is a malfunction in the SBC brake
system, we recommend that the vehicle be
transported with all wheels off the ground
using flatbed or appropriate wheel lift/dolly
equipment.
A tow bar must be used if circumstances
do not permit the use of the recommended
towing methods and the vehicle requires
towing with all four wheels on the ground.
Towing the vehicle with all four wheels on
the ground is only permissible for distances
up to 30 miles (50 km) and at a speed not
to exceed 30 mph (50 km/h). For more in-
formation, refer to “Towing the vehicle”
(page 325).
iIf the SBC brake system is activated as
the brake pedal is first depressed, you
may feel a reduced pedal resistance
and longer pedal travel than normal.
When releasing the pedal, you may also
feel the brake pedal pulsate and you
may hear a sound which is caused by
the activation of the SBC pump. This is
normal and not an indication of a mal-
function. Pedal travel returns to normal
when you release the brake pedal and
the sound soon ceases.

of the roll bar by pressing the release
button1.

Lower the roll bar. Make sure that the
fastening straps do not get caught.

cause the driver to lose control of the vehi-
cle.

Warning!
G
To help avoid personal injury during a colli-
sion or sudden maneuver, exercise care
when stowing objects in the vehicle. Put lug-
g a g e o r c a r g o i n t h e t r u n k i f p o s s i b l e . D o n o t
pile luggage or cargo higher than the seat
backs. Do not place anything on shelf be-
hind roll bar.
Parcel nets cannot secure hard or heavy ob-
jects. Warning!
G
Keep compartment lids closed. This will help
to prevent stored objects from being thrown
about and injuring vehicle occupants during
an accident.

216 OperationDriving instructionsPower assistance
Brakes
Warning!
G
The brake system requires electrical energy
for operation.
A malfunction in the vehicle’s power supply
or electrical system In such a case, the red
brake warning lamp (
page 253) and warn-
ing messages (
page 265) in the instru-
ment cluster light up while driving. To brake,
the driver must then apply significantly
greater brake pedal pressure and depress
the pedal much further to obtain the expect-
ed braking effect. If necessary, apply full
pressure to the brake pedal. Brakes are only
applied to the front wheels. Stopping dis-
tance is increased! If there is a malfunction

wheels off the ground using flatbed or ap-
propriate wheel lift/dolly equipment.
A tow bar must be used if circumstances do
not permit the use of the recommended
towing methods and the vehicle requires
towing with all four wheels on the ground.
Towing the vehicle with all four wheels on
the ground is only permissible for distances
up to 30 miles (50 km) and at a speed not to
exceed 30 mph (50 km/h). For more infor-
mation, refer to "Towing the vehicle"
(page 325).
With the engine not running, there is no
power assistance for the steering system. In
this case, it is important to keep in mind that
a considerably higher degree of effort is nec-
essary to steer the vehicle.
Warning!
G
After driving in heavy rain for some time
without applying the brakes or through wa-
ter deep enough to wet brake components,
the first braking action may be somewhat
reduced and increased pedal pressure may
be necessary to obtain expected braking ef-
fect. Maintain a safe distance from vehicles
in front.
Resting your foot on the brake pedal will
cause excessive and premature wear of the
brake pads.
It can also result in the brakes overheating
thereby significantly reducing their effec-
tiveness. It may not be possible to stop the
vehicle in sufficient time to avoid an acci-
dent.

Driving while these messages are displayed
can result in an accident. Have your brake
system checked immediately.

If the SBC brake system enters its emergen-
cy operation mode, the driver must apply

and depress the pedal much further than

If necessary, apply full pressure to the brake

Don’t add brake fluid before checking the
brake system. Overfilling the brake fluid res-
ervoir can result in spilling brake fluid on hot
engine parts and the brake fluid catching
fire. You can be seriously burned.

317 Practical hints
Flat tire

Press 0 on the electric air pump switch.

Turn the key in the ignition to
position0.
or

Press KEYLESS-GO* start/stop button
on the selector lever twice without de-
pressing the brake pedal.
The electric air pump should now be
switched off.

If the tire pressure is above 36 psi
(2.5 bar), release excess tire pressure
using the vent screw.

Detach the electric air pump.

Stow the electrical plug and the air
hose behind the flap and place the air
pump back in the trunk.
!Do not operate the air pump longer
than eight minutes without interrup-
tion. Otherwise it may overheat.
You may operate the air pump again af-
ter it has cooled off.
Warning!
G
Follow recommend inflation pressures.
Do not overinflate tires. Overinflating tires
can result in sudden deflation (blowout) be-
cause they are more likely to become punc-
tured or damaged by road debris, potholes
etc.
Do not underinflate tires. Underinflated tires
wear unevenly, adversely affect handling
and fuel economy, and are more likely to fail
from being overheated.
iThe flat tire may be transported in the
trunk when the retractable hardtop is
lowered. Use the protective sheet pro-
vided with the spare wheel. Do not ac-
tivate the tire inflation pressure
monitor until the deflated tire has been
removed from the vehicle.
