The auxiliary heating system operates
independently of the engine and
complements the vehicle heating or air
conditioning.
You can set the auxiliary heating at an outside
temperature of up to 39 ‡ (4 †) in order to:
R pre-heat the vehicle interior
R additionally warm the coolant, thereby
conserving the engine and saving fuel

39 ‡ (4 †), the auxiliary heating and heater
booster function switch off automatically.

regular intervals (at least once a month) for
approximately 10 minutes.
Make sure that the flow of hot air is not
blocked. Otherwise, the auxiliary heating
will overheat and switch off.

Warning
Free movement of the pedals must not be
impaired. This would
otherwise jeopardize the
operating and road safety of the vehicle.
Objects could get caught between the pedals
if you accelerate or brake suddenly. You will
then be unable to brake, declutch or
accelerate as intended. You could cause an
accident, thereby endangering yourself and
others.

Warning
If they are not properly closed, the doors

X Secure the load according to the loading
guidelines ( Y page 144).

G
Warning
Do not place any objects in the driver's
footwell. If you
use a floormat or carpet in the
driver's footwell, make sure that it is correctly
secured and that there is sufficient clearance
for the pedals.
Do not place several floormats on top of one
another.
Loose objects or the floormats could
otherwise get caught between the pedals if
you accelerate or brake suddenly. You will
then not be able to brake or accelerate as
intended. This could lead to accidents and
injury. G
Warning
Never leave the engine running in enclosed
spaces. The exhaust gases contain toxic carbon monoxide.
Breathing in exhaust fumes
is a health hazard and can lead to
unconsciousness or death.
! Do not depress the accelerator pedal
when starting the engine.
i If you depress the brake pedal when
starting the engine,
the pedal travel is short
and the pedal resistance is high.
Pedal travel and resistance return to
normal when you depress the brake pedal
again.

Driving in wet conditions
G
Warning
There is a danger of hydroplaning occurring,
even if you are driving slowly and your tires
have sufficient tread
depth, depending on the
depth of water on the road.
For this reason, avoid tire ruts and brake
carefully.
Driving on flooded roads If you have to drive on stretches of road on
which water has collected, the water level
must not rise above the bottom edge of the
bumper. The maximum speed at which you
may drive is walking speed.
!
Note that vehicles in front or oncoming
vehicles create waves. This could mean
that the maximum permitted water depth
is exceeded.
You must observe these notes. Otherwise,
damage may
occur
to the engine, electrics
or transmission.
Driving in winter Drive particularly carefully on slippery roads
in winter.
Avoid
sudden acceleration, steering
and braking maneuvers. G
Warning
Do not downshift for additional engine
braking on a
slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. You could lose control
of the vehicle and cause an accident.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed, shift to
the neutral position N. Try to maintain control
of the vehicle using corrective steering
! Vehicles with automatic transmission
may roll only briefly in the neutral position
N. Prolonged rolling of the wheels, e.g.
when being towed, will result in
transmission damage. Road salt may adversely affect braking
performance.
Consequently, you
may need to
depress the brake pedal more forcefully in
order to achieve normal braking force. Apply
the brakes regularly when driving for longer
periods on gritted or salted roads. This will
restore the brakes to their normal level of
performance.
When stopping the vehicle after traveling on
roads that have been salted, make sure that
the brakes are fully functional before
proceeding further.
i Fit snow chains to the outside rear wheels
(driven axle) in good time for driving on
snow, slush or ice. Comply with the
manufacturer's fitting instructions.
You will find information about winter tires
and about driving with snow chains in the
"Operation" section .
Tire grip Whereas the vehicle can be fully controlled at
a certain speed on a dry road surface, you
must reduce your speed on a wet or icy
surface to maintain the same degree of
safety.
Pay particular attention to the road
conditions at temperatures around freezing
point. When ice forms on the road surface
(e.g. due to fog), applying the brakes can
cause a
thin
layer of water to form rapidly on
the ice and tire grip will be greatly reduced.
Drive with particular care in such weather
conditions. Stopping the vehicle and switching

Warning
Make sure that the exhaust system does not
under any circumstances come into contact
with easily ignitable
material such as dry grass
or gasoline. Do not park the vehicle on dry
grassland or harvested grain fields.
Otherwise, the flammable material may ignite
