Vehicle level control
Your vehicle automatically adjusts its ride
height to
reduce fuel consumption
increase vehicle safety
The following vehicle chassis ride heights
can be selected:
Normal
RaisedThe vehicle chassis ride height is raised or
lowered according to the selected level
setting and to the vehicle speed:
At a speed above approximately above
68 mph (110 km / h) and the sporty
suspension style selected
(page 226), ride height is reduced
automatically by up to approximately
0.6in (15mm).
With decreasing speed, the ride height
is again raised to the “Normal” level.Select the “Raised” level only when re-
quired by current driving conditions. Oth-
erwise
fuel consumption may increase
handling may be impaired
iThese height adjustments are so small
that you may not notice any change.
Warning!
G
To help avoid personal injury, keep hands
and feet away from wheel housing area, and
stay away from under the vehicle when low-
ering the vehicle chassis.

Warning!
G
Never drive vehicle with trunk open while
the ski sack is removed. Deadly carbon
monoxide (CO) gases may enter vehicle in-
terior, resulting in unconsciousness and
death.iTo prevent unauthorized persons from
access to the trunk, always close the
cover.
Warning!
G
When expanding the luggage compartment,
always fold the seat cushions fully forward.
Unless you are transporting cargo, the back-
rests must remain properly locked in the up-
right position.
In an accident, during hard braking or sud-
den maneuvers, loose items will be thrown
around inside the vehicle, and cause injury
to vehicle occupants unless the items are
securely fastened in the vehicle.
Always use the cargo tie down rings
(page 241).
!You must always release the seat cush-
ion and fold it up before folding the seat
backrests forward. The upholstery on
the seat backrest may otherwise be
damaged.

240 Controls in detailLoadingLoading instructions
The total load weight including vehicle oc-
cupants and luggage / cargo should not ex-
ceed the vehicle capacity weight indicated
on the certification tag which can be found
on the left door pillar.The handling characteristics of a fully load-
ed vehicle depend greatly on the load dis-
tribution. It is therefore recommended to
load the vehicle according to the illustra-
tions shown, with the heaviest items being
placed towards the front of the vehicle.
Always place items being carried against
front or rear seat backrests, and fasten
them as securely as possible.
The heaviest portion of the cargo should al-
ways be kept as low as possible since it in-
fluences the handling characteristics of
the vehicle.
Warning!
G
Always fasten items being carried as secure-
ly as possible.
In an accident, during hard braking or sud-
den maneuvers, loose items will be thrown
around inside the vehicle and can cause in-

are securely fastened in the vehicle.
To help avoid personal injury during a colli-
sion or sudden maneuver, exercise care
when transporting cargo. Put luggage or car-
go in the trunk if possible. Do not pile lug-
gage or cargo higher than the seat backs.
Do not place anything on the rear-window
shelf.
Never drive vehicle with trunk open. Deadly

268 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 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 312) and
warning messages in the instrument cluster
(
page 318) come on while driving. To
brake, the driver must then apply signifi-
cantly greater brake pedal pressure and de-
press the pedal much further to obtain the
expected braking effect. If necessary, apply
full pressure to the brake pedal. Brakes may
only be applied to the front wheels. Stop-
ping distance is increased! If there is a mal-
function 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 infor-
mation, refer to “Towing the vehicle”
(page 381). For more information see
SBC brake system (
page 79).
With the engine not running, there is no
power assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the ve-
hicle.
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.
