X
Connect the cable provided in the trunk to the
trickle charger.
X Connect the trickle charger to 12 V socket 0043.
Consult the manufacturer's operating instruc- tions on how to do so.
The trunk lid can be closed, even if a trickle
charger is connected. Make sure that the con-
nector for both the connector cables is outside
of the vehicle.
The connector can then separate if the vehicle is moved, even if you forget to disconnect the con-
nector cables. This prevents damaging the
cables and the trickle charger.
A trickle charger connected to 12 V socket 0043
only maintains the current charge level of the
vehicle's electrical system battery. If the vehi-
cle's electrical system battery is discharged, it
needs to be charged with a battery charger. Driving tips
General driving tips
Important safety notes G
WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk of an accident.
Do not switch off the ignition while driving. G
WARNING
If you operate mobile communication equip-
ment when driving, you may be distracted
from the traffic situation. You could also lose
control of the vehicle. There is a risk of an
accident.
Only operate this equipment when the vehicle is stationary.
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 Warm up the engine at low engine speeds.
X Avoid frequent acceleration or braking.
X Have all service and maintenance work car-
ried out at the specified intervals.
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
DANGER
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases is hazardous to health
and can result in poisoning. There is a risk of
fatal injury. Therefore, never leave the engine Driving tips

conditions when doing so.
X Close the driver's door. TIREFIT kit
Important safety notes TIREFIT is a tire sealant.
You can use TIREFIT to seal punctures of up to
0.16 in (4 mm), particularly those in the tire
tread. You can use TIREFIT at outside tempera-
tures down to 00F84 ‡ (00F820 †). G
WARNING
In the following situations, the tire sealant is
unable to provide sufficient breakdown assis- tance, as it is unable to seal the tire properly:
R there are cuts or punctures in the tire larger
than those mentioned above.
R the wheel rim is damaged.
R you have driven at very low tire pressures or
on a flat tire.
There is a risk of an accident.
Do not drive the vehicle. Contact a qualified
specialist workshop. G
WARNING
The tire sealant is harmful and causes irrita-
tion. It must not come into contact with your
skin, eyes or clothing or be swallowed. Do not inhale TIREFIT fumes. Keep tire sealant away
from children. There is a risk of injury.
If you come into contact with the tire sealant,
observe the following:
R Rinse off the tire sealant from your skin
immediately with water.
R If the tire sealant comes into contact with
your eyes, immediately rinse them thor-
oughly with clean water.
R If tire sealant is swallowed, immediately
rinse your mouth out thoroughly and drink
plenty of water. Do not induce vomiting,
and seek medical attention immediately.
R Immediately change out of clothing which
has come into contact with tire sealant.
R If an allergic reaction occurs, seek medical
attention immediately.
! Do not operate the tire inflation compressor
for longer than ten minutes at a time without a break. It may otherwise overheat.
The tire inflation compressor can be operatedagain once it has cooled down.
Comply with the manufacturer's safety instruc-
tions on the tire inflation compressor label and
on the tire sealant bottle.
Using the TIREFIT kit X
Do not remove any foreign objects which have
penetrated the tire, e.g. screws or nails.

tion lock (Y page 111).
X Press on/off switch 0087on the tire inflation
compressor.
The tire inflation compressor is switched on.
The tire is inflated.
First, tire sealant is pumped into the tire. The
pressure may briefly rise to approximately
500 kPa (5 bar/73 psi).
Do not switch off the tire inflation com-
pressor during this phase.
X Let the tire inflation compressor run for a
maximum of ten minutes. The tire should then have attained a pressure of at least 180 kPa
(1.8 bar/26 psi).
If a pressure of 180 kPa (1.8 ba r/26 psi) has
been at tained after five minutes, see "Tire pres-
sure reached" (Y page 253).
If a tire pressure of 180 kPa (1.8 bar/26 psi) has not been attained after five minutes, see "Tire
pressure not reached" (Y page 253).
If tire sealant has escaped, clean it off affected
areas as quickly as possible. It is preferable to
use clean water.
If your clothes are soiled with tire sealant, have them cleaned with perchloroethylene at a dry
cleaner as soon as possible. 252

WARNING
If wheels and tires of the wrong size are used, the wheel brakes or suspension components
may be damaged. There is a risk of an acci-
dent.
Always replace wheels and tires with those
that fulfill the specifications of the original
part.
When replacing wheels, make sure to use the
correct:
R designation
R model
When replacing tires, make sure to use the
correct:
R designation
R manufacturer
R model G
WARNING
A flat tire severely impairs the driving, steer-
ing and braking characteristics of the vehicle.
There is a risk of accident.
Tires without run-flat characteristics:
R do not drive with a flat tire.
R immediately replace the flat tire with your
emergency spare wheel or spare wheel, or
consult a qualified specialist workshop.
Tires with run-flat characteristics:
R pay attention to the information and warn-
ing notices on MOExtended tires (tires with
run-flat characteristics).
Accessories that are not approved for your vehi-
cle by Mercedes-Benz or are not being used cor- rectly can impair the operating safety.
Before purchasing and using non-approved
accessories, visit a qualified specialist work-
shop and inquire about:
R suitability
R legal stipulations
R factory recommendations Information on the sizes and types of wheels and
tires for your vehicle can be found under
"Wheel/tire combinations" (Y page 285).
Tire pressure information can be found:
R on the Tire and Loading Information placard

Information on driving
Check the tire pressure when the vehicle is
heavily laden and adjust prior to a trip.
While driving, pay attention to vibrations, noises
and unusual handling characteristics, e.g. pull-
ing to one side. This may indicate that the
wheels or tires are damaged. If you suspect that a tire is defective, reduce your speed immedi-
ately. Stop the vehicle as soon as possible to
check the wheels and tires for damage. Hidden
tire damage could also be causing the unusual
handling characteristics. If you find no signs of
damage, have the tires and wheels checked at a
qualified specialist workshop.
When parking your vehicle, make sure that the
tires do not get deformed by the curb or other
obstacles. If they cannot be avoided, drive over obstacles such as curbs slowly and at an obtuse
angle. Otherwise, you may damage the wheels
or tires. Notes on high performance tires
G
WARNING
Due to the special tire tread in combination
with the optimized rubber compound, there is an increased risk of hydroplaning and skid-
ding on damp or wet road surfaces. In addi-
tion, tire traction is significantly reduced at
low outside temperatures and low tire-oper-
ating temperatures. There is a risk of an acci-
dent.
Activate ESP ®
and adapt your driving style. At
outside temperatures below 50 ‡(10 †), use
M+S tires. Operation

Before raising the vehicle, secure it from roll-
ing away by applying the parking brake and
inserting wheel chocks. Do not disengage the parking brake while the vehicle is raised.
R The jack must be placed on a firm, flat and
non-slip surface. On a loose surface, a large,
flat, load-bearing underlay must be used. On a slippery surface, a non-slip underlay must be
used, e.g. rubber mats.
R Do not use wooden blocks or similar objects
as a jack underlay. Otherwise, the jack will not
be able to achieve its load-bearing capacity
due to the restricted height.
R Make sure that the distance between the
underside of the tires and the ground does not
exceed 1.2 in (3 cm).
R Do not place your hands or feet under the
raised vehicle.
R Do not lie under the vehicle.
R Do not start the engine when the vehicle is
raised.
R Do not open or close a door or the trunk lid
when the vehicle is raised.
