Problem Possible causes/consequences and
000B Solutions
The rear window
defroster has
deactivated
prematurely or cannot
be activated. The battery has not been sufficiently charged.
X
Switch off any consumers that are not required, e.g. reading
lamps, interior lighting or the seat heating.
When the battery is sufficiently charged, the rear window
defroster can be activated again. Activating/deactivating air-
recirculation mode
General notes You can deactivate the flow of fresh air if
unpleasant odors are enteringt
he vehicle
from outside. The air already inside the
vehicle will then be recirculated.
If you switch on air-recirculation mode, the
windows can fog up more quickly, in
particular at low temperatures. Only use air-
recirculation mode briefly to prevent the
windows from fogging up.
The operation of air-recirculation mode is the
same for all control panels.

heat function
General notes The residual heat function is only available in
vehicles for Canada with automatic climate
control.
It is possible to make use of the residual heat
of the engine to continue heating the vehicle
for approximately 30 minutes after the engine
has been switched off. The heating time
depends on the temperature that has been
set.
i
The blower will run at alow speed
regardless of the airflow setting.
i If you activate the residual heat function
at high temperatures, only the ventilation
will be activated. The blower runs at
medium speed. 132

is ar isk of injury.
Make sure that all vehicle occupants always
maintain asufficient distance to the air
outlets. If necessary, redirect the airflow to
another area of the vehicle interior.
In order to ensure the direct flow of fresh air
through the air ventsi nto the vehicle interior,
please observe the following notes:
R keep the air inlet between the windshield

R Do not manually shift to alower gear to
brake the vehicle.
R If possible, do not depress the accelerator
pedal past the point of resistance
(kickdown).
R Ideally ,for the first 1000 miles (1500 km),
drive in program E. After 1,000 miles (1,500 km), you can
increase the engine spee

Important safety notes G
WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is ar isk of fatal injury. Therefore never leave
the engine running in enclosed spaces
without sufficient ventilation. G
WARNING
Flammable materials introduced through
environmental influence or by animals can
ignite if in contact with the exhaust system or
parts of the engine that heat up. There is arisk
of fire.
Carry out regular checkstom ake sure that
there are no flammable foreign materials in
the engine compartmentorint he exhaust
system.
! Do not depress the accelerator pedal
when startingt he engine.
i During acold start, the engine runs at
higher speeds to enable the catalytic
converter to reach its operating
temperature. The sound of the engine may
change during this time.

i Upshifts take place at higher engine
speeds after acold start. This helps the
catalytic converter to reach its operating
temperature more quickly. Hill starta
ssist Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient.
It holds the vehicle for
ashort time after you
have removed your foot from the brake pedal.
This gives you enough time to move your foot
from the brake pedal to the accelerator pedal
and to depress it before the vehicle begins to
roll. G
WARNING
After ashort time, hill start assist will no
longer brake your vehicle and it could roll
away. There is arisk of an accident and injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist.
X Remove your foot from the brake pedal.
The vehicle is then held for about asecond.
X Pull away.
Hill start assist is not active if:
R you are pulling away on alevel road or on

stationary on uphill gradients (Y page 146). ECO start/stop function
Introduction The ECO start/stop function switches the
engine off automatically if the vehicle is
stopped under certain conditions.
The engine start
sautomatically when the
driver wants to pull away again. The ECO
start/stop function thereby helps you to
