Important safety notes
GWARNING
If children are traveling in the vehicle, they
could:
Ropen doors, thus endangering other people
or road users
Rexit the vehicle and be caught by oncoming
traffic
Roperate vehicle equipment and become
trapped
There is a risk of an accident and injury.
Always activate the child-proof locks and
override feature if children are traveling in the vehicle. When leaving the vehicle, always take
the key with you and lock the vehicle. Never
leave children unattended in the vehicle.
Child-proof locks for rear doors (
Ypage 52).
GWARNING
If you leave children unsupervised in the vehi-
cle, they could set it in motion by, for example:
Rrelease the parking brake.
Rshift the automatic transmission out of the
parking position P.
Rstart the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
GWARNING
If persons, particularly children are subjected to prolonged exposure to extreme heat or
cold, there is a risk of injury, possibly even
fatal. Never leave children unattended in the
vehicle.
GWARNING
If the child restraint system is subjected to
direct sunlight, parts may get very hot. Chil-
dren may burn themselves on these parts,
particularly on the metal parts of the child
restraint system. There is a risk of injury.
If you leave the vehicle, taking the child with
you, always ensure that the child restraint
system is not exposed to direct sunlight. Pro- tect it with a blanket, for example. If the child
restraint system has been exposed to direct
sunlight, let it cool down before securing the
child in it. Never leave children unattended in
the vehicle.

Adjusting the air vents
Important safety notes
GWARNING
Very hot or very cold air can flow from the air
vents. This could result in burns or frostbite in
the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior.
The center and side air vents are adjustable. On vehicles with a rear-compartment air-condi-
tioning system, you can also adjust the air vents
in the roof duct.
iFor virtually draft-free ventilation, adjust the
sliders of the center air vents to the center
position.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
Rkeep the air inlet grille on the hood free of
blockages, such as ice, snow or leaves.
Rnever cover the vents or the ventilation grilles
in the vehicle interior.

compartment
Air vents (example: right-hand side of the vehicle)
You can use the air vents to ventilate the vehicle
interior on the left and right, in the rear and the
headroom.
XTo open: for the right-hand side of the vehi-
cle, turn thumbwheel ;to the left or for the
left-hand side of the vehicle, thumbwheel :

XTo close: for the right-hand side of the vehi-
cle, turn thumbwheel ;to the right or for the
left-hand side of the vehicle, thumbwheel :

Adjusting the air vents in the roof duct
!
Always leave at least one air vent open.
If the rear-compartment air conditioning is
switched on and all the air vents are closed,
the air-conditioning system may be damaged.
On vehicles with rear-compartment air condi-
tioning, adjustable air vents are integrated into
the roof duct.
XTo adjust the airflow: open or close the air
flap in air vents :as needed.
XTo adjust the air distribution: turn air
vent :to the desired position.
Operating the auxiliary heating sys-
tem
Important safety notes
GDANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such as carbon monoxide (CO) may enter the vehicle. This is the case, for example in
enclosed spaces or if the vehicle gets stuck in
snow. There is a risk of fatal injury.
Switch the auxiliary heating off in enclosed
spaces without extraction systems, e.g. in
garages. If the vehicle is stuck in snow and
you have to leave the auxiliary heating run-
ning, keep the exhaust pipe and the area
around the vehicle free of snow. To ensure anadequate supply of fresh air, open a window
on the side of the vehicle that is not facing into
the wind.

Problems with the auxiliary warm-air heater
ProblemPossible causes/consequences andMSolutions
The auxiliary heating
does not switch on.The outside temperature is above 39 ‡ (4 †). The auxiliary heating
switches off automatically.
The auxiliary heating
switches off automati-
cally and/or cannot be
switched on.The fuel tank is less thanÕfull. The auxiliary heating switches off
automatically.
XRefuel at the nearest gas station.
XThen, start the auxiliary heating several times until the fuel lines are
full.
or
The low-voltage protection system integrated in the control unit
switches off the auxiliary heating because the on-board voltage is less
than 10 V.
XHave the alternator and battery checked.
or
The fuse is blown.
XReplace the fuse; see the "Fuse allocation" supplement.
XHave the cause of the blown fuse determined at a qualified spe-
cialist workshop.
Operating the cargo compartment air
vents
If your vehicle is equipped with a roof ventilator,
you can ventilate and extract air from the cargo
compartment.
XTurn the key to position 2in the ignition lock.
XTo activate and extract air: press the upper
section of the ´switch.
The roof ventilator removes used air from the
cargo compartment.
XTo activate and ventilate: press the lower
section of the ·switch.
The roof ventilator feeds fresh air into the
cargo compartment.
XTo switch off: set the switch to the middle
position.

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.
If you leave the vehicle parked for longer than
6 weeks, the vehicle may suffer damage as a
result of lack of use. In this event, consult a
qualified specialist workshop.
Driving tips
General notes
Important safety notes
GWARNING
The driver's attention to the road must always be his/her primary focus when driving. For
your safety and the safety of others, we rec-
ommend that you pull over to a safe location
and stop before placing or taking a telephone
call. If you choose to use the telephone while
driving, please use the hands-free device and
only use the telephone when road, weather
and traffic conditions permit.
Some jurisdictions prohibit the driver from
using a mobile phone while driving a vehicle.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle covers
a distance of 44 feet (approximately 14 m)
ever yse cond.
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.
!Always observe the ground clearance of the
vehicle and avoid obstacles. On vehicles with a step, ground clearance is further restricted.
Obstacles can damage the vehicle.
If you must drive over obstacles, drive espe-
cially slowly and carefully. If necessary, have
another person direct you.
Drive sensibly – save fuel
In order to save fuel, observe the following tips:
XThe tires should always be inflated to the rec-
ommended tire pressure.
XRemove unnecessary loads.
XRemove roof carriers when they are not nee-
ded.
XWarm up the engine at low engine speeds.
XAvoid frequent acceleration or braking.
XHave all maintenance work carried out as
indicated by the service intervals in the Main-
tenance Booklet or by the service interval dis-
play.
Fuel consumption also increases when driving in cold weather, in stop-start traffic and in moun-
tainous terrain.
Overrun cutoff
If you are in overrun mode and take your foot off
the accelerator pedal, the fuel supply is cut off
when the engine speed is out of the idle speed
control range.
Drinking and driving
GWARNING
Drinking and driving and/or taking drugs and driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and judg-
ment.
The possibility of a serious or even fatal acci-
dent are greatly increased when you drink or
take drugs and drive.
