somebody becomes trapped, to interrupt the
opening procedure.
XPre-entry climate control and conveni-
ence opening with the key: press and hold
the % button on the key.
The side windows open automatically and the
blower of the climate control system is acti-
vated.
XRelease the %button.
iAt high interior temperatures, the blower is
also switched on when adoor is opened. This
means that slightly cooled air enters the vehi-
cle interior after the engine is started, to cool
the vehicle more rapidly.
Switching the residual heat function
on/off
General notes
Only vehicles with automatic climate control
have the residual heat function.
Once the engine is switched off, it is possible to
make use of the residual heat of the engine to
continue heating or ventilating the front com-
partment of the vehicle for approximately
30 minutes. The heating or ventilation time
depends on the set interior temperature.
Switching the function on/off
XTurn the key to position 0in the ignition lock
or remove it.
XPress the Ìbutton.
If the residual heat function is activated, the
indicator lamp in the Ìbutton comes on.
The blower will run at alow speed regardless
of the airflow setting.
If you activate the residual heat function at
high temperatures, only the auxiliary ventila-
tion will be activated. The blower then runs at
medium speed.
The residual heat function switches off auto-
matically

RIt is particularly important to observe the
describedorder when connecting and dis-
connecting the jumper cables.
RNever connect or disconnect the battery
terminals whil ethe engine is running.
!Alway sconnect the battery in the order
describedb elow. Never mix up the terminal
clamp disconnection/connection order and
never mix up the terminal clamps. You may
otherwise damage the vehicle electronics.

minal installation positionw hen doing so.
Otherwise ,the positive clamp may come into
contact with vehicle parts. In this case there is
ar isk that the vehicle may short-circuit and
catch fire.
The following descriptiononc onnecting and
installing the battery is base dupon the example
of the starter battery in the seat base of the
right-hand front seat. The additional battery is
connected and installe dinthe same way as the
starter battery. The auxiliary battery is located in
the seat base of the left-hand front seat.
Example: starter battery
XPlace the battery on the door sill panel as
shown and secure with handles =if neces-
sary.
XConnect positive clamp ;to positive termi-
nal :.A lwaysobserve the positive terminal
installation positions hown when doing so.
The positive leadm ust be routed parallel to
the side of the battery housing in the connec-
tion area.
XPlace the positive clamp cover on positive
terminal :.
XFold both handles =down onto the battery.
XPush the battery into the seat base until the
negative terminal can be connected.
XConnect the negative clamp to negative ter-
minal ?.
