& WARNING
If ACC initiates a braking maneuver, the brake pedal will be
retracted . Interference with the brake pedal can prevent ACC from
slowing the vehicle down and cause a crash and serious personal
injury .
• Never put anything in the driver's footwell or let anything fall
into it. An object in the driver 's footwell can interfere with the
pedals and prevent the accelerator from being used to override
ACC or prevent ACC from being switched off when the brake pedal
is depressed and also prevent the vehicle from being slowed down
or stopped.
• Only use floor mats that keep the area around the pedals free
and that can be securely fastened to the footwell.
• Never drive with your foot underneath the brake pedal.
• Always read and heed the information and WARNINGS~
& in
" Description " on
page 136.
& WARNING
• Never rely on the distance control feature of ACC alone to
prevent rear-end collisions. Always be prepared to brake and take
evasive action to avoid collisions and other accident situations.
• Never allow the closing speed between you and other vehicles
to be so high that the Adaptive Cruise Control may not be able to slow your vehicle safely. If closing speed is too high , you must
apply the brakes yourself to reduce the risk of a rear-end crash.

Before you move the selector lever from t he P position, yo u must
a lw ays app ly the b rake ped al befo re and while dep ress ing the bu tton
in the handle of the selector lever.
& WARNING
• Unintended vehicle movement can cause serious injury.
- When the selector lever is in a driving position, the vehicle
may creep, even at idle speed. Therefore do not release the
parking brake o r foot brake until you are ready to move ,
because power is transmitted to the wheel s as soon as a driving
position i s engaged.
- Do not accelerate while selecting a driving position. At this
time the engine must be at idle speed so that undue stre ss is
not placed on the clutches in the tran smission.
- Remember: -even when stopped briefly with the automatic
tran smission in "D ", "S" or "R ", engine power is being trans­
mitted to the wheels. Your vehicle could "creep" forward or
backward. When stopped, keep the brake pedal fully
depressed and use the parking brake if necessary to keep the
vehicle from rolling .
• If the selector lever is unintentionally moved into N while you
are driving, take your foot off the acc elerator pedal and wait for
the eng ine to return to idle speed before selecting a driv ing posi­
tion .
• Never shift into "R " or "P" when the vehicle is in motion.
• Never get out of th e driver's seat when the engine is running .
• If you must get out of the vehicle, move the selector lever
securely into the P pos ition and apply the parking brake firmly.
• If the engine must remain running, never have any driving
position engaged when checking under the hood . Ma ke sure the
s elector lever ha s securely engaged and is locked in "P" with the
parking brake firmly set=> page
290, "Engi ne compartment".
Otherwise, any increa se in engine speed may set the vehicle in
motion, even with the parking brake applied. •

Adaptive Air Suspension
Air suspension and damping
Applies to veh icles : w ith Adap tive Air Suspens ion
Description
Air suspension and damping can be adjus ted separately.
Adaptive Air Suspens ion is an e lectron ically controlled springing and
damping sys tem. This chass is sys tem makes it eas ie r on the d river by
adapting to the particular si tuation through imperceptible control
processes.
T he
Adaptive Air Su spen sion component regu lates ground clea rance
depending on vehicle speed and driver input . It funct ions indepen ­
dently from the load cond it io n. Ac ce le rating to a speed above a
predetermined limit will make the vehicle lower itse lf. On the other
hand, dr iv ing more slowly res ults in the vehicle r aising again at
specific speeds.
T he
damping component provides individua l control of the damping
forces . For example , w ith damping characte rist ics set to p rovide
greater comfort, damping is set somewhat harder for a brief period
only as req uir ed, for example, whe n going a ro und a curve or when
brak ing.
Sett ings
Adaptive Air Suspension provides the driver with the opportun ity to
set the chass is characte rist ics also to their individual p refe rence.
With the driving modes
Comfort, Automatic and Dynamic the dr iver
has three chass is sett ings available, ranging from comfort to spo rty.
The
Offroad mode ca n be selected for dr iv ing on poor quality
s tr etc hes of road. In addition,
Li~ provides a fif th mode, w hich can be
selected when exceptiona lly high g round clearance is needed
==> page 179, "C hass is controls ".
T he modes are set in MMI
==> page 180 .
& WARNING
The height of th e parked vehicle can change du e to temperature
fluctuations or changes in load.
0 Note
• Whenever you park yo ur vehicle, always make sure there is
ade qua te clearance above and below t he ve hicle. The height of the
parked vehicle can change as the result of temperature fluctuations,
c hanges in loa d condition and changes in the dr iv ing mode (ground
cleara nce).
• If the veh icle is be ing transported (e .g . by tow truck, tra in , sh ip,
etc.), mount the tie-down cha ins/cables over the running su rface
(circumference) of the tires. Never se cure the vehi cle by the ax le, the
suspension struts or the front or rear tow line eye. For technical
reaso ns, the p ressure in the suspension st ru ts may change dur ing the
t ransport, whic h could result in the vehicle no longer being secured
pro perly.
• If you are goi ng to tow a trailer w ith a tra iler h itch that was
not
ins talled accor ding to f actory s pecifi cations, you mus t activa te t he
t rai ler operation mode manually:::::,

Important things to do before driving
Safety is everybody's job! Vehicle and occupant safety always depends on the informed and careful driver.
For your safety and the safety of your passengers, before
driving always:
- Make sure that all lights and signals are operating
correctly.
- Make sure that the tire pressure is correct.
- Make sure that all windows are clean and afford good visi-
bility to the outside.
- Secure all luggage and other items carefully::::>
page 107.
-Make sure that nothing can interfere with the pedals.
- Adjust front seat, head restraint and mirrors correctly for your height .
- Instruct passengers to adjust the head restraints according to their height.
- Make sure to use the right child restraint correctly to
protect children ::::,
page 233, "Child Safety".
- Sit properly in your seat and make sure that your passen­ gers do the same::::,
page 85, "General recommenda­
tions".
- Fasten your safety belt and wear it properly. Also instruct
your passengers to fasten their safety belts properly
=:> page 201. •
Controls and equip­
ment Safety first Vehicle operation
What impairs driving safety?
Safe driving is directly related to the condition of the
vehicle, the driver as well as the driver's ability to concen­
trate on the road without being distracted .
The driver is responsible for the safety of the vehicle and all
of its occupants. If your ability to drive is impaired, safety
risks for everybody in the vehicle increase and you also
become a hazard to everyone else on the road::::,,& . There­
fore:
Do not let yourself be distracted by passengers or by using
a cellular telephone.
NEVER drive when your driving ability is impaired (by
medications, alcohol, drugs, etc.).
- Observe all traffic laws, rules of the road and speed limits
and plain common sense .
- ALWAYS adjust your speed to road, traffic and weather
conditions.
- Take frequent breaks on long trips. Do not drive for more than two hours at a stretch.
- Do NOT drive when you are tired, under pressure or when
you are stressed .
& WARNING
Impaired driving safety increases the risk of serious personal
injury and death whenever a vehicle is being used.•

& WARNING (continued)
• Children must always ride in child safety seats=> page 233.
Special precautions apply when installing a child safety seat on
the front passenger seat=>
page 211. •
Proper seating positions for passengers in
rear seats
Rear seat passengers must sit upright with both feet on
the floor consistent with their physical size and be prop­
erly restrained whenever the vehicle is in use.
To reduce the risk of injury caused by an incorrect seating
position in the event of a sudden braking maneuver or an
accident, your passengers on the rear bench seat must
always observe the following :
- If there are passengers in the rear seat, fold the head
restraints up on the occupied seats or slide the center
head restraint upward at least to the next notch
~ page 93.
Make sure that the seatback is securely latched in the
upright position ~
page 96.
-Keep both feet flat in the footwell in front of the rear seat.
- Fasten and wear safety belts properly~
page 205.
- Make sure that children are always properly restrained in a
child restraint that is appropriate for their size and age
~ page 233.
& WARNING
Passengers who are improperly seated on the rear seat can be seri­
ously injured in a crash.
• Each passenger must always sit on a seat of their own and
properly fasten and wear the safety belt belonging to that seat.
• Safety belts only offer maximum protection when the seatback
is securely latched in the upright position and the safety belts are
properly positioned on the body. By not sitting upright, a rear seat
passenger increases the risk of personal injury from improperly
positioned safety belts!
• Always adjust the head restraint properly so that it can give
maximum protection. •
Proper adjustment of head restraints
Correctly adjusted head restraints are an important part
of your vehicle's occupant restraint system and can help
to reduce the risk of injuries in accident situations .

and secured in the luggage compartment.
Fig. 188 Safe load
positioning: place
heavy objects as low
and as far forward as
possible.
Loose items in the luggage compartment can shift suddenly ,
changing vehicle handling characteristics. Loose items can
also increase the risk of serious personal injury in a sudden
vehicle maneuver or in a collision .
Controls and equip­
ment Safety first Vehicle operation
-
Distribute the load evenly in the luggage compartment.
- Always place and properly secure heavy items in the
luggage compartment as low and as far forward as
possible => fig. 188.
- Secure luggage using the tie-downs provided=>
page 97.
- Make sure that the rear seatback is securely latched in
place .
& WARNING
Improperly stored luggage or other items can fly through the
vehicle causing serious personal injury in the event of hard braking or an accident. To help reduce the risk of serious personal injury:
• Always put objects, for example, luggage or other heavy items
in the luggage compartment.
• Always secure objects in the luggage compartment using the
tie-down eyelets and suitable straps.
& WARNING
Heavy loads will influence the way your vehicle handles. To help
reduce the risk of a loss of control leading to serious personal
injury:
• Always keep in mind when transporting heavy objects, that a
change in the center of gravity can also cause changes in vehicle
handling:
- Always distribute the load as evenly as possible.
-Place heavy objects as far forward in the luggage compart-
ment as possible.
• Never exceed the Gross Axle Weight Rating or the Gross Vehicle
Weight Rating specified on the safety compliance sticker on the left door jamb. Exceeding permissible weight standards can cause
the vehicle to slide and handle differently.

& WARNING (conti nu ed )
• Pleas e obse rve information on s afe driving => page 190.
& WARNING
To help prevent poi sonous exhau st ga s from being drawn into the
vehicle, always keep the rear lid closed while driving.
• Never transport object s larger than tho se fitting completely
into the luggage area because the rear lid cannot be fully closed.
• If you ab solutely must drive with the rear lid open, observe the
following notes to reduce the ris k of po isoning:
- Close all windows,
- Close the Pano ramic sliding sunroof*,
- Open all air outlets in the instrument panel,
- Swit ch off the air recirculation,
- Set the fresh air fan to the h ighest speed.
& WARNING
Alway s make sure that the doors, all windows, the Panorami c
sliding sunroof* and the rear lid are secur ely closed and locked to
reduce the risk of injury when the vehicle is not being used.
• After closing the rear lid, always make sure that it is properly
clo sed and locked .
• Never leave your vehicle unattended especially with the rear lid
left open . A child could crawl into th e vehicle through the luggage
compartment and close the rear lid becoming trapped and unable
to get out . Being trapped in a vehicle can lead to serious personal
injury.
• Never let children play in or around the vehicle.
• Never let passengers ride in the luggage compartment. Vehicle
occupants must alway s be properly restrained in one of the
vehicle 's seating positions.
W Tips
• Air circulation helps to reduce window fogging. Sta le air escapes
to the outside th rough vents in the trim panel. Be sure to keep these
slo ts free and open.
• Th e tire pressure m ust correspond to the load . The tire pressure is
shown o n th e t ire pressu re label. The tire pressure label is located o n
the driver's side 8-pillar . The tire p ress ure label lists the recom­
me nded co ld tire inflation pressures fo r th e ve hicle at its max imum
capacity weight and the tires that were on your vehicle at t he time it
was manufactured. For recommended t ire pressu re s for normal loa d
conditions, p lease see chapter=>
page 322. •
Tie-downs
The lug gage c omp artm ent is equ ipped with fo ur tie­
do wns to secur e luggag e and oth er items .
Use the t ie-downs to sec ure yo ur cargo properly => page 197,
"Load ing the l uggage comp artmen t".
In a co llision , the laws of physics mean that even smaller items that
are loose in the vehicle will become heavy m issi les t hat can ca use
ser ious injury. Items in the vehicle possess energy which va ry with
veh icle speed and the weight of the item . Vehicle speed is the most
sign ifi cant factor .
For example, in a frontal coll is ion at a speed of 30 mp h (48 km/h),
the forces a cting on a 1 0-lb (4.5 kg) o bje ct are about 20 times the
normal weight of the item. This means that the weight of the item
wou ld sudden ly be abo ut 200 l bs. (9 0 kg). You can imagine the inju ­
r ies that a 200 lbs. (90 kg) item flying freely through the passenger
compar tment cou ld cause in a collision like this .
