Important safety notes G
WARNING
The ultrasonic backing up aid is only designed
to assist
you and may not detect all obstacles.
It is not a substitute for paying attention.
You are always responsible for safety and
must continue to pay attention to your
immediate surroundings when parking and
maneuvering. Otherwise, you could endanger
yourself and others. G
WARNING
Make sure that no persons or animals are in
the maneuvering range. Otherwise, they
could be injured.
The ultrasonic

backing up aid is an electronic
parking aid. It indicates visually and audibly
the distance between the rear area of your
vehicle and an object.
The ultrasonic backing up aid is activated
automatically when you switch on the ignition
and engage reverse gear.
The ultrasonic backing up aid monitors the
rear area of your vehicle using four sensors in
the rear bumper. :
Sensors in the rear bumper Range of the sensors The sensors must be free of dirt, ice and
slush; otherwise they may not function
correctly.
Clean

the sensors regularly, taking
care not to scratch or damage them

When parking,

pay particular attention to
objects above or below the sensors, such
as flower pots or trailer towbars. The
ultrasonic backing up aid does not detect
such objects when they are in the
immediate vicinity of the vehicle. You could
damage the vehicle or the objects.

Tires
G
WARNING
Do not drive with a flat tire. A flat tire affects the ability to steer or brake the vehicle. You may
lose control of the vehicle. Continued driving with a flat tire will cause excessive heat build-up
and possibly a fire. G
WARNING
Follow recommended tire inflation pressures.
Do not
underinflate tires. Underinflated tires wear excessively and/or unevenly, adversely affect
handling and fuel economy, and are more likely to fail from being overheated.
Do not overinflate tires. Overinflated tires can adversely affect handling and ride comfort, wear
unevenly, increase stopping distance, and result in sudden deflation (blowout) because they are
more likely to become punctured or damaged by road debris, potholes etc. Display messages Possible causes/consequences and

Mix the windshield washer fluid in a
container beforehand.
X At temperatures above freezing: fill the
washer fluid reservoir with a mix of water
and windshield washer concentrate (e.g.
MB SummerFit).
X At temperatures below freezing: fill the
washer fluid container with a mix of water
and MB SummerFit windshield washer
concentrate. For

information on the mixing
ratio, see (Y page 277) or use the premixed
windshield washer solution with antifreeze
available in specialist stores.

X Add the premixed washer fluid.
X To close:

until it engages.
Brake fluid level !
If you notice that the brake fluid level in
the brake fluid reservoir has fallen to the
MIN mark or less, check the brake system
immediately for leaks. Also check the
thickness of the brake linings. Visit a
qualified specialist workshop immediately.
Do not add brake fluid. This does not
correct the error. Only check the brake fluid level when the
vehicle is stationary and on a level surface.
The brake fluid level is correct if it is between
MIN
marking ;

and MAX marking : on the
brake fluid reservoir. Maintenance

intervals (see separate Maintenance

You can obtain further information from an
authorized Mercedes-Benz Center or at

The service interval message informs you of
the next service due date.
If
a

service due date has been exceeded, you
also hear a warning tone.
The multifunction display shows a service
message for several seconds, e.g.:

Service A Due Now
Service A Exceeded By 99999 Miles
The symbol and the letter indicate which type
of service is due:

Maintenance and care Z

Check the tire pressures at least once a
month.
Only check and correct tire pressures when
the tires are cold (
Y page 245).
Checking tire pressures manually To determine and set the correct tire
pressure, proceed as follows:
X
Remove the valve cap of the tire that is to
be checked.
X Press the tire pressure gauge securely onto
the valve.
X Read the tire pressure and compare it with
the recommended value on the Tire and
Loading Information placard on the
B-pillar on
the driver's side of your vehicle.
X If necessary, increase the tire pressure to
the recommended value ( Y page 245).
X If the tire pressure is too high, release air
by pressing

down the metal pin in the valve
using the tip of a pen, for example. Then,
check the tire pressure again using the tire
pressure gauge.
X Screw the valve cap onto the valve.
X Repeat these steps for the other tires. Tire pressure monitor
Important safety notes If a tire pressure monitor system is installed,
the vehicle's wheels have sensors that
monitor
the

tire pressures in all four tires. The
tire pressure monitor warns you when the
pressure drops in one or more of the tires. The
tire pressure monitor only functions if the
correct wheel electronics units are installed
on all wheels. The tire pressure monitor has a yellow
warning lamp in the instrument cluster for
indicating pressure loss/malfunctions (USA)
or pressure loss (Canada). Whether the
warning lamp flashes or lights up indicates
whether a tire pressure is too low or the tire
pressure monitoring system is
malfunctioning:
R
if the warning lamp is lit continuously, the
tire pressure on one or more tires is
significantly too low. The tire pressure
monitor is not malfunctioning.
R USA only: if the warning lamp flashes for
60 seconds

and then remains lit constantly,
the tire pressure monitor is malfunctioning. G
WARNING
The TPMS does not indicate a warning for
wrongly selected inflation pressures. Always
adjust tire

inflation pressure according to the
Tire and Loading Information placard or the
supplemental tire inflation pressure
information on the inside of the fuel filler flap.
The TPMS is not able to issue a warning due
to a sudden dramatic loss of pressure (e.g. tire
blowout caused by a foreign object). In this
case bring the vehicle to a halt by carefully
applying the brakes and avoiding abrupt
steering maneuvers. G
WARNING
Each tire, including the spare (if provided),
should be checked at least once a month
when cold and inflated to the pressure
recommended by the vehicle manufacturer
on the Tire and Loading Information placard
on the driver's door B-pillar or the tire
pressure label on the inside of the fuel filler
flap. If

your vehicle has tires of a different size
than the size indicated on the Tire and Loading
Information placard or the tire pressure label,
you should determine the proper tire pressure
for those tires.
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire
pressure telltale when one or more of your Tire pressure
