Gate operator/Canadian programming
Canadian radio-frequency laws require
transmitter signals to “time-out” (or quit)
after several seconds of transmission which
may not be long enough for the integrated
signal transmitter to pick up the signal during
programming. Similar to this Canadian law,
some U.S. gate operators are designed to
“time-out” in the same manner.
If you live in Canada or if you are having
difficulties programming a gate operator
(regardless of where you live) by using the
programming procedures, replace step 4 with
the following:
XStep 4: Press and hold the signal
transmitter button ( ;, = or ?). Do not
release this button until it has been
successfully trained.XWhile still holding down the signal
transmitter button ( ;, = or ?), “cycle”
your hand-held remote control button B
as follows: Press and hold button B for
2 seconds, then release it for 2 seconds,
and again press and hold it for 2 seconds.Repeat this sequence on the hand-held
remote control until the frequency signal
has been learned.
Upon successful training, indicator
lamp : will flash slowly and then rapidly
after several seconds.XProceed with programming step 5 and
step 6 to complete.
i Upon completion of programming the
integrated remote control, make sure you
retain the hand-held remote control that
came with the garage door opener, gate
operator or other device. You may need it
for use in other vehicles, for future
programming of an integrated remote
control, or simply for continued use as a
hand-held remote control to operate the
respective device in other situations.
Reprogramming a single signal

To program a device using a signal
transmitter button previously trained, follow
these steps:
XSwitch on the ignition.XPress and hold the desired signal
transmitter button ( ;, = or ?). Do not
release the button.

Washer system and headlamp
cleaning system
GWarning!
Washer solvent/antifreeze is highly
flammable. Do not spill washer solvent/
antifreeze on hot engine parts, because it may
ignite and burn. You could be seriously
burned.
! Always use washer solvent/antifreeze
where temperatures may fall below
freezing point. Failure to do so could result
in damage to the washer system/fluid
reservoir.
! Only use washer fluid which is suitable for
plastic lenses. Improper washer fluid can
damage the plastic lenses of the
headlamps.
! Do not use distilled or deionized water in
the washer fluid reservoir. Otherwise, the
washer fluid level sensor could be
damaged.
Fluid for the washer system, rear window
washer system, and the headlamp cleaning
system is supplied from the washer fluid
reservoir.
During all seasons, use MB Windshield
Washer Concentrate “MB SummerFit”. Mix it
with water or premixed washer solvent/
antifreeze depending on the ambient
temperature (Y page 265).

Transmission fluid level
The transmission fluid level does not need to
be checked. If you notice transmission fluid
loss or gearshifting malfunctions, have an
authorized Mercedes-Benz Center check the
transmission.
Brake fluid level
! If you find that the brake fluid in the brake
fluid reservoir has fallen to the minimum
mark or below, have the brake system
checked for brake pad thickness and leaks
immediately. Contact an authorized
Mercedes-Benz Center immediately. Do
not add brake fluid as this will not solve the
problem. For more information, see
“Practical hints”.
When checking the brake fluid level, the
vehicle must be parked on level ground.

When the vehicle has been parked for longer
than 20 minutes, the message Tire
pressure displayed only after
driving for a few minutes. appears in
the multifunction display.
iWith a spare wheel mounted, the system
may still indicate the tire inflation pressure
of the removed road wheel for some
minutes. If this happens, keep in mind that
the indicated value where the spare wheel
is mounted does not reflect the actual
spare tire inflation pressure.

Tire inflation pressure warnings
If the system detects a significant loss of tire
inflation pressure in one or more than one
tire, a message appears in the multifunction
display. In addition, an acoustic warning
sounds and the low tire pressure telltale in the
instrument cluster comes on.
The respective tire is indicated by a red
rectangle.
Restarting Advanced TPMS
GWarning!
It is the driver’s responsibility to set the tire
inflation pressure to the recommended cold
tire inflation pressure. Underinflated tires
affect the ability to steer or brake the vehicle.
You might lose control over the vehicle.
When you restart the TPMS, the system sets
new reference values for each tire.
The TPMS must be restarted when you have
adjusted the tire inflation pressure to a new
level (e.g. because of different load or driving
conditions). The TPMS is then recalibrated to
the current tire inflation pressures.
iCanada only:
The TPMS usually recognizes tire pressure
adjustments and sets new reference values
automatically. You can, however, restart
the TPMS manually as described.
Restart the TPMS after adjusting the tire
inflation pressure to the inflation pressure
recommended for the vehicle operating
condition. Tire inflation pressure should only
be adjusted on cold tires. Observe the

standard items which may be replaced) of
automatic transmission, power steering,
power brakes, power windows, power seats,
radio, and heater, to the extent that these
items are available as factory-installed
equipment (whether installed or not).
Air pressure
The amount of air inside the tire pressing
outward on each square inch of the tire. Air
pressure is expressed in pounds per square
inch (psi), kilopascal (kPa), or bar.
Aspect ratio
Dimensional relationship between tire
section height and section width expressed
in percentage.
Bar
Metric unit for air pressure. There are
14.5038 pounds per square inch (psi) to
1 bar; there are 100 kilopascals (kPa) to 1 bar.
Bead
The tire bead contains steel wires wrapped by
steel cords that hold the tire onto the rim.
Cold tire inflation pressure
Tire inflation pressure when your vehicle has
been sitting for at least 3 hours or driven no
more than 1 mile (1.6 km).
Curb weight
The weight of a motor vehicle with standard
equipment including the maximum capacity
of fuel, oil, and coolant, and, if so equipped,
air conditioning and additional optional

To assure sufficient fresh air ventilation, open
a window slightly on the side of the vehicle
not facing the wind.GWarning!
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Indicated temperatures just above the
freezing point do not guarantee that the road
surface is free of ice. The road may still be icy,
especially in wooded areas or on bridges.
GWarning!
On slippery road surfaces, never downshift in
order to obtain braking action. This could
result in drive wheel slip and reduced vehicle
control. Your vehicle’s ABS will not prevent
this type of control loss.
Do not engage the transfer case in position
LOW when driving on ice or packed snow. At
speeds below 18 mph (30 km/h) vehicle
steering is adversely affected by the LOW-
RANGE ABS.
The most important rule for slippery or icy
roads is to drive sensibly and to avoid abrupt
acceleration, braking and steering
maneuvers. Do not use the cruise control
system under such conditions.
When the vehicle is in danger of skidding, shift
the automatic transmission to neutral
position N. Try to keep the vehicle under
control by corrective steering action.
i For information on driving with snow
chains, see “Snow chains” ( Y page 180).
Road salts and chemicals can adversely
affect braking efficiency. Increased pedal
force may become necessary to produce the
normal brake effect.
Depressing the brake pedal periodically when
traveling at length on salt-strewn roads can
bring road-salt-impaired braking efficiency
back to normal.
If the vehicle is parked after being driven on
salt-treated roads, the braking efficiency
should be tested as soon as possible after
driving is resumed.GWarning!
Make sure not to endanger any other road
users when carrying out these braking
maneuvers.
Driving instructions
Drive sensibly – save fuel
To save fuel you should:
R Keep tires at the recommended inflation
pressures.
R Remove unnecessary loads.
R Allow engine to warm up under low load
use.
R Avoid frequent acceleration and
deceleration.
R Have all maintenance work performed at
the intervals specified in the Maintenance
Booklet and as required by the
Maintenance system. Contact an
authorized Mercedes-Benz Center.
Fuel consumption is also increased by driving
in cold weather, in stop-and-go traffic, on
short trips and in mountainous areas.
Drinking and driving
GWarning!
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
judgment.
The possibility of a serious or even fatal
accident are 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
taking drugs.

Hydroplaning
Depending on the depth of the water layer on
the road, hydroplaning may occur, even at low
speeds and with new tires. In heavy rain or
when conditions indicate possible
hydroplaning:XReduce vehicle speed.XAvoid track grooves in the road.XApply brakes cautiously.
Standing water
! Do not drive through flooded areas.
Before driving through water, determine its
depth.
If you must drive through standing water,
drive slowly to prevent water from entering
the passenger compartment or the engine
compartment. Water in these areas could
cause damage to electrical components or
wiring of the engine or transmission, or
could result in water being ingested by the
engine through the air intake causing
severe internal engine damage. Any such
damage is not covered by the Mercedes-
Benz Limited Warranty.
Prevent water from entering the passenger
compartment or the engine compartment. If
you must drive through standing water, keep
in mind that
R the maximum depth of the water may not
exceed 19 in (48 cm)
R you must drive slowly
For more information, see “Driving through
water” ( Y page 187).
Off-road driving
GWarning!
Do not load items on the roof. It may cause
instability during some maneuvers which
could result in an accident.
Drive slowly in unknown terrain. This will
make it easier to recognize unexpected
obstacles and avoid damage to the vehicle.
To help avoid the vehicle rolling over, never
turn it around on steep inclines. If the vehicle
cannot complete the attempted climb, back it
down in reverse gear.
Do not drive along the side of a slope. The
vehicle might otherwise rollover. If in doing so
the vehicle begins to show a tendency to roll,
immediately steer into a line of gravity
(straight up or downhill).
Never let the vehicle roll backwards in idle.
You may lose control of the vehicle if you use
only the service brake. For information on
driving downhill, see “Driving downhill”.GWarning!
Sand, dirt, mud and other material having
friction property can cause exceptional wear
and tear as well as brake failure.
Have the brakes checked for dirt build-up and
cleaned. There is otherwise a risk that full
braking power may not be available in an
emergency.
Read this chapter carefully before you begin
off-road travel.
Familiarize yourself with the vehicle
characteristics and gear changing before you
attempt any difficult terrain off-road driving.
We recommend that you start out with easy
off-road travel.
