Fig. 68 On the steering wheel: 9 o'clock and 3 o'clock position.
Adjust the steering wheel position before setting off and only when the vehicle is stationary ⇒ .
Push down the lever ⇒ Fig. 67① .
Adjust the steering wheel so that you can hold it with both hands at its circumference at the 9
o'clock and 3 o'clock positions with your arms slightly bent ⇒ Fig. 68 .
Push the lever up firmly until it is flush with the steering column trim ⇒ .
WARNING
Incorrect use of the steering column position adjustment and incorrect adjustment of the steering
wheel can cause serious or fatal injuries.
After adjusting the steering column, always move lever ⇒ Fig. 67① up so that it engages securely.
This prevents the steering column from moving spontaneously while the vehicle is in motion.
Never adjust the steering wheel when the vehicle is in motion. If you determine that a readjustment
is necessary when driving, stop the vehicle safely and adjust the steering wheel to the correct
position.
The steering wheel must always point towards the chest and not towards the face. This ensures that
the driver front airbag provides maximum protection in the event of an accident.
While driving, always keep both hands on the outside of the steering wheel at the 9 o'clock and 3
o'clock positions⇒ Fig. 68 . This reduces the risk of injury if the driver front airbag is triggered.
Never hold the steering wheel at the 12 o'clock position, or in any other manner, e.g. at the hub of
the steering wheel. If the driver front airbag is triggered, you could sustain serious injuries to the
arms, hands and head.
Seats and head restraints
Front seats
Introduction
This chapter contains information on the followingsubjects:
⇒ Mechanically adjusting the front seat
⇒ Folding the front passenger seat backrest forwards
The following section describes the options for adjusting the front seats. Always ensure that you
adjust the correct sitting position ⇒ Sitting position .
WARNING
Always adjust the front seats to their correct position before any journey and ensure that all
passengers have fastened their seat belts.
Push the front passenger seat as far back as possible.
Adjust the driver seat so that there is at least 25 cm between your breastbone and the hub of the
steering wheel. Adjust the driver seat by moving it forwards or backwards so that you are able to
press the pedals to the floor with your knees still slightly angled and the distance to the dash panel
in the knee area is at least 10 cm. If your build makes it impossible to fulfil this requirement, you
must contact a qualified workshop so they can make any necessary modifications.
Never travel with the backrest tilted far back. The further back the backrest is tilted, the greater the
risk of injury caused by incorrect seat belt routing or an incorrect sitting position.
Never travel with the backrest tilted far forwards. When a front airbag is triggered, it could force the
seat backrest backwards and injure vehicle occupants on the rear seats.
Adopt and maintain the greatest possible distance from the steering wheel and dash panel.
You should always sit upright with your back against the seat backrest with the front seats properly
adjusted. Do not position any body part too close to where the airbags are fitted.
The risk of serious injury is increased for passengers on the rear seat if they are not sitting upright
because the seat belts are incorrectly positioned.
WARNING
Incorrect adjustment of the seats can cause accidents and serious injuries.
The seats must be adjusted only when the vehicle is stationary, or else the seat could change
position unexpectedly while the vehicle is in motion, leading to a loss of control of the vehicle.
Furthermore, an incorrect seating position is adopted while adjusting the seat.
Adjust the height and tilt of the seat or move it forwards and backwards only when the area around
the seat is clear.
The adjustment range of the seats must not be restricted by any items.
Adjust the tilt angle of the rear seats or move them forwards and backwards only when the area
around the seats is clear.
The adjustment and locking areas of the seats must not be soiled.
Operate the lever to adjust the lumbar support.
Take your weight off the backrest and turn the handwheel to adjust the backrest position.
Front passenger seat: take your weight off the backrest and operate the lever to adjust the backrest
position (depending on equipment).
Move the lever up or down, several times if necessary, to adjust the seat height.
Pull the lever to push the front seat forwards or backwards. The front seat must engage after the
lever has been released.
Folding the front passenger seat backrest forwards
Fig. 70 Front passenger seat: folding backrest forwards.
First read and observe the introductoryinformation and safety warnings⇒Introduction
The front passenger seat backrest can be folded forwards to a horizontal position.
The front passenger front airbag must be switched off if any items are to be transported on the front
passenger seat when folded forwards ⇒ Airbag system .
Folding the front passenger seat backrest forwards
Remove any items from the front passenger seat cushion ⇒ .
Lower the front passenger seat down as far as possible.
Push the front passenger seat as far back as possible.
Push the head restraint all the way down.
Release the front passenger seat backrest in the direction of the arrow ⇒ Fig. 70① .
WARNING
Incorrect use of turn signals, a failure to use turn signals, or forgetting to switch off a turn signal can
confuse other road users. This could lead to accidents and serious injuries.
Always activate the turn signal in good time when changing lanes and performing overtaking or
turning manoeuvres.
Always switch off the turn signal once the lane change or overtaking or turning manoeuvre has been
completed.
The hazard warning lights also work when the ignition is switched off ⇒ In an emergency .
Some settings can be stored in the user accounts of the personalisation function and therefore
change when the user account changes ⇒ Personalisation .

roof frame and being injured.
When the glass roof is open, the electric sun blind can be closed only up to the front edge of the
glass roof.
Heating and air conditioning system
Heating, ventilating, cooling
Introduction
This chapter contains information on the followingsubjects:
⇒ Front controls
⇒ Air recirculation mode
⇒ Seat heating
⇒ Steering wheel heating
⇒ Troubleshooting
The following systems may be installed in the vehicle
Both the manual air conditioning system and Climatronic heat, cool and dehumidify the air. It works
most effectively when the windows and the glass roof are closed. If heat has built up in the vehicle
interior, ventilating the vehicle can speed up the cooling process.
Display of activated functions
Lit up LEDs on rotary knobs and buttons indicate that the function is switched on.
WARNING
Poor visibility through the windows increases the risk of collisions and accidents, which can cause
serious injuries.
Keep all windows free from ice, snow and condensation to maintain good visibility.
Adjust the heating, air conditioning system and rear window heating so that condensation does not
form on the windows.
Only set off once all windows are clear.
Use air recirculation mode for a short period only. If the cooling system is switched off, condensation
can form on the windows very quickly in air recirculation mode and reduce visibility considerably.

Switch-off conditions
The steering wheel heating will be switched off automatically if one of the following conditions is
met:
Seat heating for the driver seat is switched off (if Link seat/steering wheel heating is active).
Power consumption is too high.
There is a fault in the steering wheel heating system.
Troubleshooting
First read and observe the introductoryinformation and safety warnings⇒Introduction
Eco driving profile ⇒ Driving profile selection and 4MOTION Active Control .
Avoid driving at full throttle
Never drive the vehicle at its top speed. The drag coefficient increases at excessively high speeds.
This in turn increases the force needed to move the vehicle.
Reduce idling
Pull away immediately with low engine speeds. If you are stopped for a long period, do not allow the
engine to idle but switch it off, e.g. when in a traffic jam or at a railway crossing.
In vehicles with an activated start/stop system, the engine can switch off automatically when the
vehicle is stopping and when the vehicle is stationary ⇒ Start/stop system .
Refuel moderately
A full fuel tank increases the weight of the vehicle. A fuel tank that is half or two thirds of the way
full is sufficient for journeys in urban traffic in particular.
Avoid short journeys
A cold engine has very high fuel consumption. The optimum operating temperature is reached only
after driving a few kilometres. The fuel consumption is above average at very low ambient
temperatures, e.g. in winter ⇒ Fig. 97 . Plan journeys economically and combine short journeys.
Carry out regular maintenance
Regular maintenance is an essential prerequisite for economical driving and increases the service life
of the vehicle.
Observe the tyre pressures
Low tyre pressures does not just mean greater wear, but also increase the rolling resistance of the
tyres and thus the fuel consumption. Use optimised rolling resistance tyres.
Adjust the tyre pressure according to the load. Observe the information on the tyre pressure sticker
⇒ Useful information about wheels and tyres
Tyre Pressure Loss Indicator or Tyre Pressure Monitoring System ⇒ Tyre monitoring system .
Use low viscosity engine oils
Fully synthetic engine oils with a low viscosity decrease frictional resistance in the engine and are
distributed better and more quickly, especially during cold starts.
Do not drive with unnecessary loads in the vehicle
You can reduce fuel consumption by clearing out the luggage compartment before setting off, for
example by removing empty drink crates or unused child seats.
To keep the vehicle's air resistance as low as possible, remove any add-on parts and equipment such
as ski racks, bicycle racks and roof carriers once you have finished using them.
