When starting a cold engine, the engine may be a bi t noisy for a
shor t w hile. This is because the hydraulic valves are working to
bring up the oil pressure . This is norma l and no cause for concern .
If the engine does not start immediately, stop cranking the engine
after 10 seconds . Wa it 30 seconds, t hen try to restart the eng ine.
& WARNING
Ne ver sta rt the engine in an en clo sed area su ch a s in your garage
with the garage door clo sed . The exhau st fumes are poi sonous!
0 Note
• Avoid high engine speeds, full gas or heavy engine loads if the
eng ine has not warmed up to its operating temperature . You cou ld
damage the engine.
• Do not try to start the engine by pu lling or pushing .
~ For the sake of the environment
Do not let your veh ic le stand and warm up . Be ready to drive off
right away. T his way, you prevent unnecessary exhaust emissions.

On the road -----------------
Parking
To prevent a parked vehicle from rolling away, there are a
few things you should do.
When you park your vehicle, do the following
- Stop the vehicle using the brake pedal.
- Pull the switch to apply the electromechanical parking
brake.
- Move the selector lever into the
P position => &.
- Switch off the engine and remove the ignition key from
the ignition lock.
When you park your vehicle on hills, do the
following
- Stop the vehicle using the brake pedal.
- Pull the switch to apply the electromechanical parking
brake.
- If you are parking headed
downhill, turn the front wheels
toward the curb.
- If you are parking headed
uphill, turn the front wheels
awayfrom the curb.
- Move the selector lever into the
P position.
- Switch off the engine and remove the ignition key from
the ignition lock.
& WARNING
This is how you can reduce the risk of injury when leaving your
vehicle.
Controls and equip­ ment
&, WARNING (continued)
• Never park the vehicle where it can come in contact with dry
grass, spilled fuel or any other flammable materials.
• When parking on hills, always turn the wheels so that the front
wheels will first roll into the curb, if the vehicle should start to roll.
• Never allow anyone -especially small children -to remain
in the
vehicle when it is locked. Locked doors make it more difficult for
rescuers to access the passenger compartment in the event of an
emergency. Danger to life!
• Never leave children unsupervised in the vehicle. Children
could release the parking brake or move the gearshift lever out of
gear. The vehicle could start to roll away and cause an accident.
• No matter what the season is, the temperature in a parked
vehicle can reach dangerous levels.
0 Note
• Please exercise care when you park your vehicle in parking areas
with parking barriers or curbs . Parking barriers and curbs vary in
height and could damage your bumper and related components as
the front of your vehicle moves over a barrier or curb that is too high, as you park or as you back out of a parking spot. In order to be
sure that no such damage can occur, you may wish to stop short of
having the front tires of your car touch the parking barrier or curb.
• Please also exercise exceptional care when you drive up or down
steep ramps or drive over curbs or other obstacles, for which the
vehicle is not designed , because components of the vehicle close to
the ground, such as bumper covers, spoilers and suspension and
exhaust system components, may become damaged. •

h _e _ ro_ a_d __________________________________________________ _
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 prevents the vehicle
from rolling backward.
- You can release the switch once you are sure that you are
developing enough forward momentum at the wheels as
you depress the accelerator.
Depending on the weight of the rig (vehicle and trailer) and the
severity of the incline, you may roll backwards as you start. You can
prevent rolling backwards by holding the parking brake switch
pulled out and accelerating -just as you would when starting on a
hill with a conventional hand brake. •
Emergency braking
In the event that the conventional brake system fails or
locks.
- Pull the switch and continue to pull it to slow your vehicle
with the parking brake in an emergency.
- As soon as you release the switch or accelerate, the
braking process stops.
If you pull the switch and hold it above a speed of about 5 mph (8
km/h), the emergency braking function is initiated . The vehicle is
braked at all four wheels by activating the hydraulic brake system.
Brake performance is similar 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 the switch is released
, or the accelerator pedal is depressed, emer­
gency braking stops.
& WARNING
Emergency braking should only be used in an emergency, when
the normal foot brake has failed or the brake pedal is obstructed .
Using the parking brake to perform emergency braking will slow
your vehicle as if you had made a full brake application. The laws
of physics cannot be suspended even with ESP and its associated
components (ABS, ASR, EDS). In corners and when road or
weather conditions are bad, a full brake application can cause the
vehicle to skid or the rear end to break away -risking an
accident. •
Driver messages in the instrument cluster
Caution: Vehicle parked too steep
This message appears when the parking brake is applied on an
incline that exceeds about 30%.
In this case the braking power of the parking brake may
not be
adequate
to prevent the vehicle from rolling unintentionally.
Please release parking brake
This message appears, when a gear is selected and the accel erator
pedal is depressed -release the parking brake.
Press brake pedal to release parking brake
This driver message appears when the switch to release the parking
brake was pressed. The parking brake can only be released if you
press the brake or accelerator pedal and press the switch at the
same time .
~ Parking brake malfunction !
This driver message appears together with the yellow 'Jlf symbol
when there is a parking brake malfunction.

• Alway s remember th at Ad aptive Cru ise Control has limits - it
doe s not rea ct when you dri ve toward s an ob stac le or something
e lse on or near the road th at is not mov ing , such as ve hic le s
s topped in a traffic jam , a sta lled or di sabled vehicle.
• Alway s remember th at the Ad aptive Cru ise Control cannot
detect a vehicle that i s driving to wards you in your tr affi c la ne and
that it cannot det ect narrow veh icles su ch a s motor cycles and
bicycle s.
[ i] Tips
• For sa fety reasons, the stored speed is deleted when the ign it ion
is turned off .
• When Adaptive Cru ise Control is switched on, the Electronic
Stabilization Program (ESP) is also automatically activated.
• Damage caused by accidents (e.g . if the vehic le is damaged
when parking) can affect the radar sensor settings. This can cause
the system to malfunct ion or switch off completely.
• In winter conditions, you should check the radar sensor cover
before driving to make sure it is free of ice and snow. If necessary ,
clean the area near the radar sensor
carefully => page 139, fig. 151.
• To ensure that the radar sensor is not blocked, foreign objects
(e.g. stickers, larger license plate mounts, add -on parts) must not
cover the area near the radar
sensor=> page 139, fig . 151. The area
near the radar sensor must not be painted, either .•

How does Adaptive Cruise Control work?
Vehicles traveling ahead are detected with the aid of the
radar sensor.
Fi g. 152 Ra dar sens or
me asuremen t range
A forward -look ing radar sens or in the fro nt b umper monitors the
traffic situation ahead . Vehicles moving in your direction can be
de tec ted up to a distance of a bout 140 yards ( 130 meters) but the
Adaptive Cruise Contro l cannot detect vehicles that are stopped or
stal led, obstac les that do not move or narrow vehic les like motorcy ­
cles and
bicycles.=> fig. 152 .
Open road
When the road is clear, Adaptive Cruise Contro l works like cruise
co ntrol. The stored speed requested is main tained .
Driving in tr affi c
If you start to catch up with a vehic le in front of you, Adap tive Cruise
Control automatically slows your vehic le to a speed that will he lp
you stay a safe distance back .
If the vehicle in front acce lerates, Adaptive Cruise Control a lso accel -
erates up to the speed that you have set . .,_

ACC sensor blocked:
• The ACC sensor is dirty. The ACC system is not react ing, or is not
reacting correctly, to vehic les traveling ahead.
• It is possible that you are driving on a road with very light traffic
without any thing at the side of the road (e.g. guard rai ls, traffic
s igns, trees). As soon as a vehicle is detected by the system again,
it returns to its control range and the text message d isappears .
The ACC sensor is located in the area under the front license plate .
I f there is a loss of operation due to heavy contamination, this area
should cleaned to restore proper operation.

Safety tips
The side ass ist detec tion may be li mit ed when dr iv ing a round
narrow street corners, on hilly streets, and under poor weather
conditions.
I t is possible that the radar sensors may a ls o detec t other objects,
such as high or staggered guardrails.
Side ass ist does not measu re actual la ne w idth. The system
assumes a fixed lane width. Detection in the left and right lanes is
based on this assumed lane width. When driving on narrow roads or
when driv ing to the left or right of the center of a travel lane, it is
possible that vehicles wi ll be detected that are
not in the lane next
to the lane you are using.

-Never rely only on side assist when changing lanes .
- Always check rear view mirrors to make sure that it is safe to
change lanes .
• Side a ssist cannot detect all vehicle s under all conditions ­
danger of a cc ident!
• Side assist cannot detect vehicles in time to alert you when
they approach from behind at very high speed, or fall drop back
very quickly.
• The radar sensor 's
vi sion can be reduced or entirely blocked by
rain , snow , and heavy spray . This can result in side as sist not
adequately detecting vehicles or , in some cases , not dete cting
them at all . Always keep an eye on the direction you are traveling
and the relevant area around the vehicle .
• Please note that side assist indicates there are approaching
vehicles , or vehicles in your blind spot , only after your vehicle has
reached a driving speed of at lea st 37 mph (60 km /h).
• Side assist signal does not work around tight corners (turning
radius less than 218 yards , or 200
