Important information You can switch the auxiliary heating on/off
and set the operating duration using the
remote control. You can use up to 4 remote
control units on the vehicle. These must be
synchronized for the receiver in your vehicle
(Y page 126). The remote control has a maximum range of
approximately 600 meters. This range is
reduced by:
R sources of interference
R solid objects between the remote control
and the vehicle
R the remote control being in an unfavorable
position in relation to the vehicle
R transmitting from an enclosed space

DANGER
If a switch-on time has been selected, the
auxiliary heating switches on automatically.
R If the ventilation is insufficient, poisonous
exhaust gases can collect, in particular car-
bon monoxide. This is the case in enclosed
spaces, for example. There is a risk of fatal
injuries.
R If highly flammable substances or flamma-
ble materials are nearby, there is a risk of a
risk of fire and explosion.
Always deactivate the preselected switch-on
times if you stop the vehicle in such or similar situations.
Use the timer to: R activate/deactivate immediate heating
mode
R set up to three switch-on times R
set the operating duration from 10to
120 minutes or to continuous operation
R set the heating level (preselected temper-
ature) to a range between 10 and 30

WARNING
Batteries contain toxic and corrosive substan- ces. If batteries are swallowed, it can result in
severe health problems. There is a risk of fatal injury.
Keep batteries out of the reach of children. If
a battery is swallowed, seek medical attention immediately. H
Environmental note Batteries contain dangerous
substances. It is against the
law to dispose of them with
the household rubbish. They
must be collected separately
and recycled to protect the
environment. Dispose of batteries in an
environmentally friendly
manner. Take discharged
batteries to a qualified spe-
cialist workshop or a special
collection point for used bat-
teries.
If the indicator lamp on the remote control
flashes red rapidly, the remote control battery
is discharged. You should replace the remote
control battery.
You need a battery of the type CR2430, which can be obtained at any qualified specialist
workshop. 130

Visual check of the vehicle exterior X
In particular, check the following compo-
nents on the vehicle, and on the trailer as
necessary:
R license plates, vehicle lighting, turn sig-
nals, brake lamps and wiper blades for
dirt and damage
R tires and wheels for firm seating, correct
tire pressure and general condition
R trailer tow hitch for play and security
The trailer coupling is one of the most
important vehicle parts with regard to
road safety. The separate instructions
issued by the manufacturer pertaining to operation, care and maintenance should
be observed.
X Rectify any noticeable defects before com-
mencing the journey.
Checks in the vehicle Emergency equipment/first-aid kit

accessible, complete and ready for use.
The first aid and breakdown assistance equip-
ment is in the front door stowage compart-

WARNING
Objects in the driver's footwell may restrict
the clearance around the pedals or block a
depressed pedal. This jeopardizes the oper-
ating and road safety of the vehicle. There is a risk of an accident.
Stow all objects securely in the vehicle so that
they do not get into the driver's footwell.
When using floormats or carpets, make sure
that they are properly secured so that they do not slip or obstruct the pedals. Do not place
several floormats or carpets on top of one
another. G
WARNING
Unsuitable footwear can hinder correct usage of the pedals, e.g.:
R shoes with thick soles
R shoes with high heels
R slippers
There is a risk of an accident. 138

WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.

on steep downhill gradients and for
driving:
R on steep mountain roads
R in mountainous terrain
R in arduous conditions 0037
Use the braking effect of the engine
on extremely steep downhill gradi-
ents and long downhill stretches. Driving tips
Accelerator pedal position Your style of driving influences how the auto-
matic transmission shifts gear:
R little throttle: early upshifts
R lots of throttle: later upshifts
Kickdown Use kickdown for maximum acceleration:
X Depress the accelerator pedal beyond the
pressure point.
The automatic transmission shifts to the
next gear down, depending on the engine
speed.
X Ease off on the accelerator pedal once the
desired speed is reached.
The automatic transmission shifts up again.
Maneuvering Maneuvering in a tight space:
X Control the vehicle's speed by braking
carefully.
X Depress the accelerator pedal slightly and
evenly.
i You can shift back and forth between
drive position Dand reverse gear Rat low
speeds without applying the brakes. This
can help you, for example when rapidly
maneuvering the vehicle or rocking it out of snow or slush.
