!
Do not operate the windshield wipers when
the windshield is dry, as this could damage
the wiper blades. Moreover, dust that has col-
lected on the windshield can scratch the glass
if wiping takes place when the windshield is
dry. If it is necessary to switch on the windshield
wipers in dry weather conditions, always use
washer fluid when operating the windshield
wipers.
!If the windshield wipers leave smears on the
windshield after the vehicle has been washed
in an automatic car wash, wax or other resi-
dues may be the reason for this. Clean the
windshield using washer fluid after washing
the vehicle in an automatic car wash.
!Vehicles with rain/light sensor:
Switch the wipers off in dry weather. Other-
wise, dirt or optical effects may cause unde-
sired windshield wiper sweeps. This could
then damage the windshield wiper blades or
scratch the windshield.
The windshield will no longer be wiped properly
if the wiper blades are worn. Replace the wiper
blades twice a year (
Ypage 97), ideally in
spring and fall.

Replacing the wiper blades
GWARNING
If the wind shield wipers begin to move while
you are changing the wiperblades, you could
be trapped by the wiper arm. There isa risk of
injury.
Always switch off the windshield wipers and
ignition before changing the wiper blades.
!Never open the hood if a windshield wiper
arm has been folded away from the wind-
shield.
Never fold a windshield wiper armwithout a
wiper blade back onto the windshield/rear
wind ow.
Hold the windshield wiper arm firmly when
you change the wiper blade. If you release the
windshield wiper arm without a wiperblade
and itfalls onto the windshield, the windshield
may be damaged by the force of the impact.
We recommend that you have the wiper
blades replaced at a qualified specialist work-
shop.
!Only hold the wiperblade by the wiperarm.
You could otherwise damage the wiper rub-
ber.
The wind shield will no longerbe wipedproperly
if the wiper blades are worn. Replace the wiper
blades twice a year, ideally in spring and fall.

Wet road surfaces
If you have been driving for a long time in heavy
rain without braking, there may be a delayed
response when you first apply the brakes. This
may also occur after driving through a car wash
or deep water.
You must depress the brake pedal more firmly.
Maintain a longer distance to the vehicle in
front.
While paying attention to the traffic conditions,
you should brake the vehicle firmly after driving
on a wet road surface or through a car wash. This
heats the brake discs, so that they dry more
quickly, which protects them against corrosion.
Limited braking performance on salt-
treated roads
When driving on salted roads, salt may start to
build up on the brake disks and brake pads. Thiscan increase braking distances considerably.
Maintain a greater distance to the vehicle in
front.
To remove any build-up of salt that may have
formed:
XApply the brakes at the start of the journey,
occasionally during journey and at the end of
the journey. Make sure that you do not endan-
ger 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 inspection
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 thickness
never falls below 0.12 in (3 mm). Have the brake pads checked and replaced at a qualified spe-
cialist workshop, if necessary.
Do not solely rely on the brake pad wear sensor.
It is strongly recommended that you have the
brake pads checked at a qualified specialist
workshop at every service displayed in the main-
tenance 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 a few
100 kilometers. Until then, compensate 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:
Rbrake discs that have been approved by
Mercedes-Benz
Rbrake 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 and brake pads/
linings on an axle at the same time. Always
install new brake pads/linings when replacing
brake discs.
Parking brake
GWARNING
If you must brake the vehicle with the parking brake, the braking distance is considerably
longer and the wheels could lock. There is an
increased danger of skidding and accidents.
Only use the parking brake to brake the vehi-
cle 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 tips135
Driving and parking
Z
XBrake immediately in order to increase the
distance from the vehicle in front.
or
XTake evasive action provided it is safe to do
so.
If you want the distance warning function to
assist you, the function must be activated and
operational.
Due to the nature of the system, particularly
complicated driving conditions may cause the
system to display an unnecessary warning.
With the help of the radar sensor system, the
distance warning function can detect obstacles
that are in the path of your vehicle for an exten-
ded period of time.
Up to a speed of 45 mph (70 km/h), the distance
warning function can also react to stationary
obstacles, such as stopped or parked vehicles.
If you approach an obstacle and the distance
warning function detects a risk of a collision, the
system will alert you both visually and acousti-
cally.
In particular, the detection of obstacles can be
impaired in the case of:
Rdirt, ice or anything else covering the sensors
Rsnow or heavy rain
Rinterference from other radar sources
Rthere are strong radar reflections, for exam-
ple in parking garages
Ra narrow vehicle traveling in front, e.g. a
motorbike
Ra vehicle traveling in front on a different line
Following damage to the front end of the vehicle,
have the configuration and operation of the
radar sensor checked at a qualified specialist
workshop. This also applies to collisions at slow
spe eds w
here there is no visible damage to the
front of the vehicle.
Activating/deactivating the distance

Adaptive Brake Assist
iObserve the "Important safety notes" sec-
tion for driving safety systems (Ypage 54).
GWARNING
Adaptive Brake Assist cannot always clearly
identify objects and complex traffic situa-
tions.
In such cases, Adaptive Brake Assist can:
Rintervene unnecessarily
Rnot intervene
There is a risk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake. Terminate the
intervention in a non-critical driving situation.
GWARNING
Adaptive Brake Assist does not react:
Rto people or animals
Rto oncoming vehicles
Rto crossing traffic
Rto stationary obstacles
Rwhen cornering
As a result, the Adaptive Brake Assist may not
intervene in all critical conditions. There is a
risk of an accident.
142Driving systems
Driving and parking
Always pay careful attention to the traffic sit-uation and be ready to brake.
Adaptive Brake Assist aids you when braking
during hazardous situations at speeds above
20 mph (30 km/h). With the help of Adaptive
Brake Assist, the distance warning signal can
detect obstacles that are in the path of your
vehicle for an extended period of time.
When you approach an obstacle and adaptive
Brake Assist detects that there is a risk of a col- lision, adaptive Brake Assist calculates the brak-
ing force necessary to avoid a collision. Should
you apply the brakes forcefully, adaptive Brake
Assist will automatically increase the braking
force to the calculated level.
XKeep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes function as usual again if:
Ryou release the brake pedal
Rthere is no longer any danger of a collision
Rno obstacle is detected in front of your vehicle
Adaptive Brake Assist is then deactivated.
Up to the maximum vehicle speed, adaptive
Brake Assist can react to moving obstacles that
have already been recognized as such at least
once over the period of observa tion. Ad
aptive
Brake Assist does not react to stationary obsta-
cles.
In particular, the detection of obstacles can be
impaired if:
Rdirt, ice or anything else covering the sensors
Rsnow or heavy rain
Rinterference from other radar sources
Rthere are strong radar reflections, for exam-
ple in parking garages
Ra narrow vehicle traveling in front, e.g. a
motorbike
Ra vehicle traveling in front on a different line
If adaptive Brake Assist is not available due to a
malfunction in the radar sensor system, the full
brake boosting effect with the help of BAS
remains available.
Following damage to the front end of the vehicle,
have the configuration and operation of the
radar sensor checked at a qualified specialist
workshop. This also applies to collisions at slow
speeds where there is no visible damage to the
front of the vehicle.
Lane Tracking package
Blind Spot Assist
General notes
Blind Spot Assist monitors the areas on either
side of the vehicle that are not visible to the
driver with two lateral, rear-facing radar sensors
in the bumper. It supports you from speeds of
approximately 20 mph (30 km/h). A warning
display in the exterior mirrors draws your atten-
tion to vehicles detected in the monitored area. If you then switch on the corresponding turn
signal to change lane, you will also receive an
optical and audible collision warning.
Important safety notes
GWARNING
Blind Spot Assist does not react to:
Rvehicles overtaken too closely on the side,
placing them in the blind spot area
Rvehicles which approach with a large speed
differential and overtake your vehicle
As a result, Blind Spot Assist may not give
warnings in such situations. There is a risk of
an accident.
Always observe the traffic conditions care-
fully, and maintain a safe lateral distance.
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is no substitute for
attentive driving. Always ensure that there is
sufficient distance to the side for other road
users and obstacles.

Monitoring range of the sensors
In particular, the detection of obstacles can be
impaired in the case of:
Rdirt, ice or anything else covering the sensors
Rpoor visibility, e.g. due to fog, heavy rain or
snow
Rnarrow and short vehicles, e.g. motorcycles
or bicycles
Rvery wide lanes
Rnarrow lanes
Rvehicles not driving in the middle of their lane
Rbarriers or other road boundaries
Vehicles in the monitoring range are then not
indicated.
Blind Spot Assist monitors the area approx-
imately 10 ft (3.0 m) behind your vehicle and
approximately 1.6 ft (0.5 m) to 11.5 ft (3.5 m)
each side of it. The monitoring range behind the
vehicle may also be larger depending on the sit-
uation.
If the lanes are narrow, vehicles driving in the
lane beyond the lane next to your vehicle may be
indicated, especially if the vehicles are not driv-
ing in the middle of their lane. This may be the
case if the vehicles are driving on the inner side
of their lane.
Due to the nature of the system:
Rwarnings may be issued in error when driving
close to crash barriers or similar solid lane
borders.
Rwarnings may be interrupted when driving
alongside particularly long vehicles, for exam-
ple trucks, for a prolonged time. The two sensors for Blind Spot Assist are inte-
grated into the sides of the rear bumper. Make
sure that the bumper is free of dirt, ice or slush
in the vicinity of the sensors. The radar sensors
must not be covered, for example by rear-moun- ted cycle racks or overhanging loads. Following
a severe impact or in the event of damage to the
bumper, have the function of the radar sensors
checked at a qualified specialist workshop.
Blind Spot Assist may otherwise not work prop- erly.
Indicator and warning display
Blind Spot Assist is not active at speeds below
approximately 20 mph (30 km/h). Vehicles in
the monitoring range are then not indicated.

RBlind Spot Assist is malfunctioning
Blind Spot Assist is active from a speed of
20 mph (30 km/h). If a vehicle is detected in the
blind spot monitoring range, red warning
lamp :on the corresponding side lights up.
This warning occurs when a vehicle enters the
blind spot monitoring range from behind or from
the side. When you overtake a vehicle, the warn- ing only occurs if the difference in speed is less
than 14 mph (22 km/h).
Yellow indicator lamp :goes out if reverse gear
is engaged. Blind Spot Assist is then deactiva-
