erly if the wiper blade is worn. This may pre-
vent you from observing the traffic conditions.
Information on replacing the wiper blade can be found under "Replacing wiper blades"
(
Y page

110). Replacing the wiper blades
Important safety notes G
WARNING
If the windshield wipers begin to move while
you are changing the wiper blades, you
could be trapped by the wiper arm. There is
a risk of injury.
Always switch off the windshield wipers and
ignition before changing the wiper blades.
! Never open the hood/tailgate or rear
doors if a windshield wiper arm has been
folded away from the windshield/rear win-
dow.
Never fold a windshield wiper arm without a
wiper blade back onto the windshield/rear
window.
Hold the windshield wiper arm firmly when
you change the wiper blade. If you release
the windshield wiper arm without a wiper
blade and it falls onto the windshield/rear
window, the windshield/rear window may
be damaged by the force of the impact.
Mercedes-Benz recommends that you have
the wiper blades changed at a qualified spe-
cialist workshop.
! Only hold the wiper blade by the wiper
arm. You could otherwise damage the wiper
rubber.
Wiper blades are wear parts. The windshield
will no longer be wiped properly if the wiper
blades are worn. This may prevent you from
observing the traffic conditions.
Please observe the service indicator after
changing the wiper blades of the windshield
wiper.
Service indicator Replacement wiper blades for the windshield
wiper have a service indicator on the tip of the
wiper blade.
Depending on the amount of use, the service
indicator will change color from black to yel-
low.110

is an increased danger of skidding and acci-
dents.
Only use the parking brake to brake the
vehicle when the service brake is faulty. Do
not apply the parking brake too firmly. If the
wheels lock, release the parking brake until
the wheels begin turning again. The brake lamps are not illuminated when you
brake the vehicle using the parking brake.
As a rule, you may only apply the parking
brake when the vehicle is stationary.
X To apply the parking brake: depress park-
ing brake pedal ; firmly.
The red F (only USA) or J (only Can-
ada) indicator lamp in the instrument cluster
lights up if the engine is running.
X To release the parking brake: depress the
brake pedal and keep it depressed.
X Pull release handle :.
The parking brake is released abruptly. The
red F (only USA) or J (only Canada)
indicator lamp in the instrument cluster
goes out.
Exceptionally, if the service brake fails, the
parking brake can be used to brake the vehicle
in an emergency.
X Emergency braking: pull release handle :
and gradually depress parking brake
pedal ;. Switching off the engine
Important safety notes G
WARNING
The automatic transmission switches to neu-
tral position N when you switch off the
engine. The vehicle may roll away. There is a
risk of an accident.
After switching off the engine, always switch
to parking position P. Prevent the parked
vehicle from rolling away by applying the
parking brake.
! If the coolant temperature is very high, e.g.
after driving on hilly roads, leave the engine
running at idle speed for about
two minutes
before turning it off.
This allows the coolant temperature to
return to normal.
Vehicles with automatic transmission X
Stop the vehicle.
X Shift the transmission to position j.
X Apply the parking brake.
X Turn the key to position u in the ignition
lock and remove it.
The immobilizer is activated.
If you switch the engine off with the trans-
mission in position k or h, the automatic
transmission shifts to i automatically.
If you then open one of the front doors or
remove the key, the automatic transmission
automatically shifts to j.
If you shift the automatic transmission to
i before switching off the engine, the
automatic transmission remains in i even
if a front door is opened.
X Secure the vehicle to prevent it from rolling
away

of the journey. Make sure that you do not
endanger other road users when doing so.
Checking the brake pad thickness In addition to monitoring using the brake pad
wear sensor, regularly monitor and check all of
the brake pads by performing a visual inspec-
tion to look for pad material wear.
If you are unable to check the brake wear on
the inside of the wheels, remove the wheels
with the tools provided.
Make sure that the brake pad material thick-
ness never falls below
0.12 in (3 mm). Have
the brake pads checked and replaced at a
qualified specialist workshop, if necessary.
Do not solely rely on the brake pad wear sen-
sor.
It is strongly recommended that you have the
brake pads checked at a qualified specialist
workshop at every service displayed in the
maintenance interval indicator, prior to long
journeys and whenever the wheels are
removed.
New brake discs and brake pads/
linings New brake pads and brake discs only reach
their optimal braking effect after about
60 miles

(100 kilometers). Until then, compen-
sate for this by applying greater force to the
brake pedal.
For safety reasons, Mercedes-Benz recom-
mends only installing the following brake discs
and brake pads/linings:
R brake discs that have been approved by
Mercedes-Benz
R brake pads/linings that have been approved
by Mercedes-Benz or are of an equivalent
standard of quality
Other brake discs or brake pads/linings can
compromise the safety of your vehicle.
Always replace all brake discs or brake pads/
linings on an axle at the same time and only
have them replaced at a qualified specialist
workshop. When replacing the brake discs,
always have the brake pads/linings replaced
at the same time. Parking brake G
WARNING
If you must brake the vehicle with the park-
ing brake, the braking distance is considera-
bly longer and the wheels could lock. There
is an increased danger of skidding and acci-
dents.
Only use the parking brake to brake the
vehicle when the service brake is faulty. Do
not apply the parking brake too firmly. If the
wheels lock, release the parking brake until
the wheels begin turning again.
When driving on wet roads or dirt-covered sur-
faces, road salt and/or dirt may get into the
parking brake. This causes corrosion and a
reduction of braking force.
In order to prevent this, drive with the parking
brake lightly applied from time to time. When
doing so, drive for a distance of approximately
110 yds (100 m) at a maximum speed of
12 mph (20 km/h

).
The brake lamps are not illuminated when you
brake the vehicle using the parking brake. Driving in wet conditions
Hydroplaning G
WARNING
There is a danger of hydroplaning occurring,
even if you are driving slowly and your tires
have sufficient tread depth, depending on
the depth of water on the road. There is a
risk of an accident.
For this reason, avoid tire ruts and brake
carefully.
Therefore, in heavy rain or other conditions in
which hydroplaning can occur, drive as fol-
lows:
R reduce your speed
R avoid tire ruts
R apply the brakes with care Driving tips
