Seat heater
The seat heaters can be switched on with the electronic
key in steering lock positions 1 or 2.Notes:
When in operation, the seat heater consumes a large
amount of electrical power. It is not advisable to use the
seat heater longer than necessary.
The seat heaters may automatically switch off if too
many power consumers are switched on at the same
time, or if the battery charge is low. When this occurs,
the indicator lamp in the switch will blink (both
indicator lamps blink during rapid seat heating mode).
The seat heaters will switch on again automatically as
soon as sufficient voltage is available.
If the blinking of the indicator lamps is distracting to
you, the seat heaters can be switched off.

The cargo area can be enlarged by placing the seat
cushions in a vertical position and removing them. To
remove each seat cushion, pull up the lever (6) on the
underside of the seat and pull the seat cushion out its
hinge pins (7).Folding the backrest forward:
When folding the backrest forward, the hinge pins (7)
must re st in t he brackets at t he backrest. It is not
necessary to remove the head restraints before folding
the backrest forward if the seat cushion has been
removed.
When reinstalling the seat cushion, be sure to lock the
respective seat cushion into its hinge pins (7).
In addition, when transporting extremely long items,
push front passenger seat forward, remove its head
restraint and lower its backrest to the rear.
Notes:
It must be ensured that the heating elements of the rear
window defroster are not damaged by cargo rubbing

Power assistance
BrakesExcessive use of salt and other snow melting chemicals
spread on roads during the winter months may cause a
build up of moisture or residue to form on the braking
components. This build up or residue could cause light
corrosion of the braking components if the vehicle is
parked with the brakes cold. Apply steady and even
braking pressure when stopping the vehicle to warm up
and dry the brake components.
Important
Please pay attention to the function of the brake assist
system (BAS), see page 225.
If the parking brake is released and the brake warning
lamp in the instrument cluster stays on, the brake fluid
level in the reservoir is too low.
Brake pad wear or a leak in the system may be the
reason for low brake fluid in the reservoir.
Have the brake system inspected at an authorized
Mercedes-Benz Center immediately.
All checks and service work on the brake system should
be carried out by an authorized Mercedes-Benz Center.
Wa r n i n g !
When the engine is not running, the brake and
steering systems are without power assistance.
Under these circumstances, a much greater effort is
necessary to stop or steer the vehicle.Wa r n i n g !
After driving in heavy rain for some time without
applying the brakes or through water deep enough
to wet brake components or salty road conditions,
the first braking action may be somewhat reduced
and increased pedal pressure may be necessary to
obtain expected braking effect. Be sure to 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 effectiveness. It may
not be possible to stop the vehicle in sufficient time
to avoid an accident.
