Pulling away
General notes
G WARNING
If the engine speed is above the idling speed
and you engage transmission position D or R ,
the vehicle could pull away suddenly. There is
a risk of an accident.
When engaging transmission position D or R ,
always firmly depress the brake pedal and do
not simultaneously accelerate.
Depress the accelerator carefully when pulling
away.
The vehicle locks centrally once you have pulled
away. The locking knobs in the doors drop down.
You can open the doors from the inside at any
time.
You can also deactivate the automatic locking
feature ( Y
page 84). It is only possible to shift the transmission from
position P to the desired position if you depress
the brake pedal. Only then is the parking lock
released.
If you do not depress the brake pedal, the
DIRECT SELECT lever can still be moved but the
parking lock remains engaged.
i Upshifts take place at higher engine speeds
after a cold start. This helps the catalytic con-
verter to reach its operating temperature
more quickly.
Information on the automatic release of the
electric parking brake ( Y
page 164).
Hill start assist Hill start assist helps you when pulling away for-
wards or in reverse on an uphill gradient. It holds
the vehicle for a short time after you have
removed your foot from the brake pedal. This
gives you enough time to move your foot from
the brake pedal to the accelerator pedal and to
depress it before the vehicle begins to roll.
G WARNING
After a short time, hill start assist will no lon-
ger brake your vehicle and it could roll away.
There is a risk of an accident and injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist.
Hill start assist is not active if: R
you are pulling away on a level road or on a
downhill gradient. R
the transmission is in position \\ .R
the electric parking brake is applied. R

ECO start/stop function
Introduction
Hybrid vehicles: observe the notes on the ECO
start/stop function in the separate operating
instructions.
The ECO start/stop function switches the
engine off automatically if the vehicle is stopped
under certain conditions.148
Driving
Dr ivi ng an d parking

Observe the legal requirements for the country
in which you are driving. Some jurisdictions pro-
hibit the driver from using a mobile phone while
driving a vehicle.
If you make a call while driving, always use
hands-free mode. Only operate the telephone
when the traffic situation permits. If you are
unsure, pull over to a safe location and stop
before operating the telephone.
Bear in mind that at a speed of only 30 mph
(approximately 50 km/h), the vehicle covers a
distance of 44 ft (approximately 14 m) per sec-
ond.
Drive sensibly – save fuel Observe the following tips to save fuel: X
The tires should always be inflated to the rec-
ommended tire pressure. X
Remove unnecessary loads. X
Remove roof racks when they are not needed. X
Warm up the engine at low engine speeds. X
Avoid frequent acceleration or braking. X
Have 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 hilly ter-
rain.
Drinking and driving
G WARNING
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 is greatly increased when you drink or
take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or tak-
ing drugs. Emission control
G WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.
Certain engine systems are designed to keep
the level of poisonous components in exhaust
fumes within legal limits.
These systems only work at peak efficiency if
they are serviced exactly in accordance with the
manufacturer's specifications. Always have
work on the engine carried out at a qualified
specialist workshop . Mercedes-Benz recom-
mends that you use an authorized Mercedes-
Benz Center for this purpose. In particular, work
relevant to safety or on safety-related systems
must be carried out at a qualified specialist
workshop.
The engine settings must not be changed under
any circumstances. Furthermore, all specific
service work must be carried out at regular
intervals and in accordance with the Mercedes-
Benz service requirements. Details can be found
in the Maintenance Booklet.
ECO display The ECO display provides feedback on how eco-
nomical your driving characteristics are. The
ECO display assists you in achieving the most
economical driving style for the selected set-
tings and prevailing conditions. Your driving
style can significantly influence the vehicle's
consumption. Driving tips 165

G DANGER
If th e exhaust pipe is blocke d or adequate
ventilation is no t possible, poisonous gase s
suc h as carbon monoxide (CO) may ente r th e
vehicle. This is th e case, e.g. if th e vehicl e
become s trapped in snow. There is a ris k of
fatal injury.
If you leav e th e engin e or th e auxiliary heating
running, mak e sur e th e exhaust pipe and area
around th e vehicl e are clear of snow. To
ensur e an adequate supply of fresh air, open a
window on th e side of th e vehicl e that is no t
facing int o th e wind.
Hav e your vehicl e winter-proofe d at a qualified
specialist workshop at th e onset of winter.
Drive particularly carefully on slipper y roa d sur -
faces. Avoid sudden acceleration , steering and
braking maneuvers . Do no t use th e cruise con-
trol or DISTRONI C PLUS.
If th e vehicl e threaten s to skid or canno t be
stoppe d when moving at low speed:X
Shift th e transmission to position N .
The outside temperature indicator is no t
designed to serve as an ice-warning device and
is therefor e unsuitable for that purpose .
Changes in th e outside temperature are dis-
played after a short delay.

Cruise cont rol
Gene ra l notesCruis e control maintains a constan t roa d speed
for you. It brakes automatically in order to avoid
exceedin g th e set speed. Change int o a lower
gear in goo d time on lon g and steep downhill
gradients . This is especially important if th e
vehicl e is laden . By doin g so, you will mak e use
of th e braking effec t of th e engine. This relieves
th e load on th e brak e system and prevents th e
brakes from overheating and wearing to o
quickly.
You can use cruise control if you wan t to drive at
a steady speed for a prolonged period of time.
You can store any roa d speed abov e 20 mph
(30 km/h).
Import ant safety notesIf you fail to adapt your drivin g style, cruise con-
trol can neither reduce th e ris k of an acciden t

Notes on driving with MOExtended tires with a
flat tire ( Y
page 328).
Vehicles equipped with MOExtended tires are
not equipped with a TIREFIT kit at the factory. It
is therefore recommended that you additionally
equip your vehicle with a TIREFIT kit if you mount
tires that do not feature run-flat properties, e.g.
winter tires. A TIREFIT kit can be obtained from
a qualified specialist workshop.
Winter operation
General notes Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
Observe the notes in the "Changing a wheel"
section ( Y
page 362).
Driving with summer tires At temperatures below 45 ‡ (+7 †), summer
tires lose elasticity and therefore traction and
braking power. Change the tires on your vehicle
to M+S tires. Using summer tires at very cold
temperatures could cause cracks to form,
thereby damaging the tires permanently.
Mercedes-Benz cannot accept responsibility for
this type of damage.
G WARNING
Damaged tires can cause tire inflation pres-
sure loss. As a result, you could lose control of
your vehicle. There is a risk of accident.
Check the tires regularly for signs of damage
and replace any damaged tires immediately.
M+S tires

Tire pressure loss warning system
(Canada only)
General notes While the vehicle is in motion, the tire pressure
loss warning system monitors the set tire pres-
sure using the rotational speed of the wheels.
This enables the system to detect significant
pressure loss in a tire. If the speed of rotation of
a wheel changes as a result of a loss of pressure,
a corresponding warning message will appear in
the multifunction display.
You can recognize the tire pressure loss warning
by the Run Flat Indicator Active Press
'OK' to Restart message which appears in
the Service menu of the multifunction display.
Information on the message display can be
found in the "Restarting the tire pressure loss
warning system" section ( Y
page 352).
Important safety notes The tire pressure warning system does not warn
you of an incorrectly set tire pressure. Observe
the notes on the recommended tire pressure
( Y
page 346).
The tire pressure loss warning does not replace
the need to regularly check the tire pressure. An
even loss of pressure on several tires at the
same time cannot be detected by the tire pres-
sure loss warning system.
The tire pressure monitor is not able to warn you
of a sudden loss of pressure, e.g. if the tire is
penetrated by a foreign object. In the event of a
sudden loss of pressure, bring the vehicle to a
halt by braking carefully. Avoid abrupt steering
movements. The function of the tire pressure loss warning
system is limited or delayed if: R
snow chains are mounted on your vehicle's
tires. R
road conditions are wintry. R
you are driving on sand or gravel. R
you adopt a very sporty driving style (corner-
ing at high speeds or driving with high rates of
acceleration). R
you are driving with a heavy load (in the vehi-
cle or on the roof).
Restarting the tire pressure loss warn-
ing system Restart the tire pressure loss warning system if
you have: R
changed the tire pressure R
changed the wheels or tires R
mounted new wheels or tires X
Before restarting, make sure that the tire
pressures are set properly on all four tires for
the respective operating conditions.
The recommended tire pressure can be found
on the Tire and Loading Information placard
on the B-pillar on the driver's side. Addition-
ally, a tire pressure table is attached to the
fuel filler flap. The tire pressure loss warning
system can only give reliable warnings if you
have set the correct tire pressure. If an incor-
rect tire pressure is set, these incorrect val-
ues will be monitored. X
Also observe the notes in the section on tire
pressures ( Y
page 346). X
Make sure that the SmartKey is in position 2
in the ignition lock ( Y
