Operation with the timer
Important safety notes
GDANGER
If a switch-on time has been selected, the
auxiliary heating switches on automatically.
RIf 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.
RIf 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.

Useful information
This Operator's Manual describes all models as
well as standard and optional equipment of your
vehicle that were available at the time of going
to print. Country-specific variations are possi-
ble. Note that your vehicle may not be equipped
with all of the described functions. This also
applies to systems and functions relevant to
safety.
Read the information on qualified specialist
workshops (
Ypage 27).
Breaking-in notes
The first 1000 miles (1500 km)
New or replaced brake pads and brake disks
only reach their optimum braking effect after a
few 100 miles (a few 100 kilometers). Until then,
compensate for this by applying greater force to
the brake pedal.
For the service life and economy of your vehicle
it is crucial that you break in the engine with due
care.
RTherefore, protect the engine for the first
1000 miles (1500 km) by driving at varying
vehicle and engine speeds.
RAvoid overstraining the vehicle and high
engine speeds during this period, e.g. driving
at full throttle. Do not exceed Øof the max-
imum speed for each gear.
RDo not change down a gear manually in order to brake.
RTry to avoid depressing the accelerator pedal
beyond the point of resistance (kickdown).
RThe shift ranges 3,2or 1should only be
engaged when driving slowly, e.g. when driv-
ing in mountainous terrain.
After 1000 miles (1500 km), you can increase
the engine speed gradually and accelerate the
vehicle to full speed.
iYou should also observe these notes on
breaking-in if the engine or parts of the drive
train on your vehicle have been replaced.
Driving
Important safety notes
GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
GWARNING
If the parking brake has not been fully
released when driving, the parking brake can:
Roverheat and cause a fire
Rlose its hold function.
There is a risk of fire and an accident. Release
the parking brake fully before driving off.
If you park the vehicle for more than
three weeks:
Rconnect the batteries to a trickle charger or
Rdisconnect the vehicle's starter battery or
Rswitch off the electrical system using the bat-
tery main switch (Ypage 116) and
Rdisconnect the vehicle's auxiliary battery
Otherwise, you need to check the battery's con-
dition of charge every three weeks, since
standby power consumption can drain the bat-
tery. If the battery voltage is lower than 12.2 V,
the battery must be charged. Otherwise, the
battery may be damaged by exhaustive dis-
charging.
Be sure to observe the notes on disconnecting
and charging the batteries under "Battery"
(
Ypage 223). You can obtain information about
trickle chargers from a qualified specialist work-
shop.
Battery isolating switch

the battery main switch. You could otherwise
damage components of the electrical system.
You can use the battery isolating switch to dis-
connect the power supply to all your vehicle's
consumers. This will prevent uncontrolled bat-
tery discharge caused by off-load current con-
sumption.
If your vehicle is equipped with an auxiliary bat-
tery in the engine compartment, you will need to
disconnect both batteries. Only then is the elec- trical system fully disconnected from the power
supply.
iOnly switch the vehicle to de-energized
using the battery main switch if:
Rthe vehicle is stationary for a lengthy period
Rit is absolutely necessary
After the power supply has been activated,
you will need to reset the side windows
(
Ypage 71).

Preparing for a journey
Visual check of the vehicle exterior
XIn particular, check the following components
on the vehicle, and on the trailer as necessary:
Rlicense plates, vehicle lighting, turn signals,
brake lamps and wiper blades for dirt and
damage
Rtires and wheels for firm seating, correct
tire pressure and general condition
Rtrailer 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.
Rthat contour markings on attachments and
bodies are in good condition
XRectify any noticeable defects before com-
mencing the journey.
Checks in the vehicle
Emergency equipment and first-aid kit
XCheck the equipment to make sure that it is
accessible, complete and ready for use.
The first aid and breakdown assistance equip-
ment is in the front door stowage compartments
and behind the driver's seat.
Vehicle lighting
XTurn the key to position 2in the ignition lock.
XCheck the lighting system with the aid of a
second person.
XReplace defective bulbs (Ypage 87).
Before driving off
GWARNING
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.
GWARNING
Unsuitable footwear can hinder correct usage of the pedals, e.g.:
Rshoes with thick soles
Rshoes with high heels
Rslippers
There is a risk of an accident.
Wear suitable footwear to ensure correct
usage of the pedals.
XSecure the load as per the loading guidelines
(Ypage 208).
XStow luggage items securely. Secure the load
as per the loading guidelines (Ypage 208).
XMake sure that the floormats and carpets are
properly secured so that they cannot slip and
obstruct the pedals.
XClose all doors.
Starting the engine
GWARNING
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.
!Do not depress the accelerator pedal when
starting the engine.
XBefore starting the engine, make sure that:
Rall the doors are closed.
Rall the vehicle occupants are wearing their
seat belts correctly.
Rthe parking brake is applied.
iIf you depress the brake pedal before start-
ing the engine, the pedal travel is short and
pedal resistance is high.
If you depress the brake pedal again after
starting the engine, pedal travel and resist-
ance will be back to normal again.
