ECON
The ECON mode helps to save fuel .
The air conditioning is turned off in ECON mode. "ECON" means
" E conomy". By switching off the air conditioning (compressor), you
save fuel.
Please note that vehicle interior temperature cannot be lower than
the outside temperature in the ECON mode. The air is not cooled or dehumidified .
If the vehicle inter ior becomes too hot or if the windows fog up, ECON
mode should be turned off. As soon as the
( AUTO] button in the air
conditioning controls is pressed, the system automatically leaves the
ECON mode, and the air conditioning compressor is turned on
again. •
Automatic recirculation mode
An air quality sensor detects increased concentrations of
pollutants in the outside air and automatically switches
to recirculation mode .
We recommend that you always keep automat ic air recirculat ion ON
to prevent polluted outside air from entering the vehicle interior.
If the
air quality sensor located in the air conditioning system detects
polluted outside air, the sensor decides whether the air pollution can
be reduced by the facto ry-insta lled pollutant fi lter or whe ther it is
necessary to switch to air recirculation. With heavy concentrations of
pollutants, the air conditioning system is switched a utomat ically to
recirculation mode and the supply of outside air is blocked . As soon .,.

A cold engine may sound loud after it has been started. This is due to
the hydraulic valves building up oil pressure. This is normal and is not
a need for concern.
If the engine does not start immediately, stop trying after 10 seconds
and then try to restart the engine about 30 seconds later .
& WARNING
Never start or let the engine run in a confined or enclosed area.
Exhaust fumes from the engine contain carbon monoxide , a color­
less and odorless gas. Carbon monoxide can be fatal if inhaled.
• Never leave the engine idling unattended. An unattended
vehicle with a running engine poses a danger of personal injury or
theft .
0 Note
• Avoid high eng ine speeds, fast accelerat io n or heavy engine loads
wh ile the engine is still cold. This could damage the engine.
• The engine cannot be started by push ing or towing the vehicle.
~ For the sake of the environment
To avoid unnecessary engine wear and to reduce exhaust emissions,
do not let your vehicle stand and warm up. Be ready to drive off imme­
diately after starting your vehicle. Maintain moderate speed unti l the
engine is completely warm. Remember, the engine performs best at
operating temperature .•

Your vehicle is equipped with an electromechanical parking brake
which replaces the handbrake. The parking brake is designed to
prevent the vehicle from rolling unintentionally.
In addition to the normal functions of a traditional hand brake, the
electromechanical parking brake provides various convenience and
safety functions.
Emergency brake
An emergency brake ensures that the vehicle can be slowed even if
the normal brakes fail~ page 125, "Emergency braking".
Controls and equip ­
ment Safety first
Indicator lights
•
If the parking brake is applied with the ignition turned on, the
indicator light in the instrument cluster (U.S. models:=.., Canadian
models: ©) and in the switch
«el) will come on.
• If the parking brake is applied with the ignition turned off, the
indicator light in the instrument cluster (U.S. models:=., Canadian
models: ©) and in the switch
«fl) will come on for about 30 seconds
and then go out.
& WARNING
If the vehicle is stationary and the transmission is engaged with
the engine running, the engine should not be speeded up (e.g.
manually from under the hood). Otherwise the vehicle will start to
move -you run the risk of an accident.
0 Note
If the warning/indicator light (U.S . models: BRAKE, Canadian models:
«I» ) flashes in the instrument cluster, there is a brake system
malfunction . By pressing the [CHECK! button, you can bring up a
driver message which explains the malfunction in more detail. If the
message
Parking brake ! Please contact workshop appears, there is
a parking brake malfunction which you should have repaired immedi­
ately by an authorized dealership~ page 28.
[ i] Tips
• You can apply the parking brake at any time -even with the igni­
tion turned off . The ignition must be turned on in order to release the
parking brake.
• Occasional noises when the parking brake is applied and released
are normal and are not a cause for concern.
• The parking brake goes through a self-test cycle at regular inter­
vals -when the vehicle is parked. Any associated noises are normal. •

Starting off with a trailer
To prevent rolling back unintentionally on an incline, do
the following:
- Keep the switch pulled and depress the accelerator. The
parking brake stays applied and p reve nts the vehicle from
rolling backward .
- You can release t he switch once you are sure t hat you are
deve loping enough forward momentum at the whee ls as
you depress the acce lerator .
Depending on the we ight of the rig (vehicle and trailer) and the
severity of the incline, yo u may roll backwards as you start. You can
prevent rol ling backwards by holding the park ing bra ke sw itch pulled
out and accelerating -just as you wou ld when starting on a hill with a
conventional hand brake .•
Emergency braking
In the event that the conventional brake system fails or
locks.
- P ull the swi tch and cont inue to pull it to s low your veh icle
with the parking brake in an emergency .
- As soon as you re lease the sw itc h or accelerate, the
braking process stops .
If you pull the switch and hold it above a speed of abou t 5 mp h (8
km/h), the emergency braking function is init iated. The vehicle is
bra ked at all fou r wheels by activat ing the hydraulic b rake system.
Brake performance is s imilar to making an emergency stop~,&.
So that emergency braking is not activated by mistake, an audible
warning tone (buzzer) sounds when the switch is pulled . As soon as
Controls and equip ­
ment Safety first
the switch is released, or the accelerator pedal is depressed, emer­
gency braking s tops.
& WARNING
Em erg ency braking should only be u sed in an emergen cy, wh en
the no rmal foot brake ha s failed o r the brake pedal i s obstructed.
U sing the park ing b rake to perform emerg ency braking will slow
your vehicl e as if you had made a full brake application . The laws
of phy sic s c annot be su spen ded even wi th ESP and it s ass ociated
c omponents (ABS, ASR , ED S). In corn ers and when r oad or
weather condit ion s are bad , a full brake application can cause the

& WARNING (continued)
• Please note that inadvertently "resting" your foot on the accel­
erator pedal causes the cruise control not to brake. This is because
the cruise control is overridden by the driver's acceleration.
[ i] Tips
The brake lights illuminate as soon as the brakes decelerate automatically. •
Changing speed
-Press lever in the
0 or O direction=> page 126, fig. 136
to increase or decrease your speed.
- Release the lever to save that speed.
Change speed in increments of 1 mph (1 km/h) by lightly pressing the
lever. If you keep the lever pressed down, you will alter your speed in
S mph (10 km/h) increments.
You can also press the accelerator pedal down to increase your speed,
e.g. if you want to pass someone. The speed you saved earlier will
resume as soon as you release the accelerator pedal.
If, however, you exceed your saved speed by S mph (10 km/h) for
longer than S minutes, the cruise control will turn off temporarily .
The green symbol in the display~
page 126, fig. 13 7 is replaced with
a white symbol. The saved speed remains the same.•

apply the brake s your self to reduc e the ri sk of a rear-end cra sh .
• Never re st you r foot on the accelerator pedal , especially when
the Adaptive Cruise Control is being used. Pressure on the acceler­
ato r will override the ACC braking function and prevent the brakes
from being applied when ACC detects a situation when the brakes
must be applied.
• Never use Adaptive Cruise Control when you cannot drive safely
at a steady speed, including on city st reets , on winding roads or
when road conditions are poor (for example , on ice, gravel , in fog,
heavy rain or on wet roads that increase the ris k of hydroplaning ).
• The radar sensor's
vision can be reduc ed by rain, snow and
heavy road spray . These and similar conditions can prevent vehi ­
cle s up ahead from being accurately detected and in some cases
they may not be detected at all . Do not use ACC when the radar
sen sors cannot ac curately detect vehicles moving ahead of you in
traffic .
• Alway s turn off Adaptive Crui se Control when entering turn
lanes , exit lanes and construction zones o r in similar situat ions
because the vehicle will automatically ac celerate to the stored
speed when the road ahead is clear .
• To prevent unintended operation , always switch ACC off when
it is not being used .
[ i] Tips
• For safety reasons, the stored speed is deleted when the ignition
i s turned o ff.
• When Adapt ive Cruise Control is switched on, the Electronic Stabi­
li zation Program ( ESP) is also automa tica lly activ ated.
