There is amalfunction in the engine electronics.
R There is amalfunction in the fuel supply.
X Before attempting to start the engine again, turn the SmartKey
in the ignition back to position 0or press the Start/Stop button
repeatedly until all indicator lamps in the instrumen tcluster go
out.
X Try to start the engine again (Y page 149). Avoid excessively
long and frequent attempt stostart the engine as these will drain
the battery.
If the engine does not start after several attempts:
X Consult aqualified specialist workshop. The engine does not
start
.You cannot hear
the starter motor. The on-board voltage is too low because the battery is too weak
or discharged.
X
Jump-star tthe vehicle (Y page 326).
If the engine does not start despite attemptstoj ump-start it:
X Consult aqualified specialist workshop. The starter motor was exposed to
athermal load that was too high.
X Allow the starter motor to cool down for approximately two
minutes.
X Try to start the engine again.
If the engine still does not start:
X Consult aqualified specialist workshop. The engine is not
running smoothly and
is misfiring. There is
amalfunction in the engine electronics or in amechanical
componentoft he engine management system.
X Only depress the accelerator pedal slightly.
X Have the cause rectified immediately at aqualified specialist
workshop.
Otherwise, non-combusted fuel may get into the catalytic
converter and damage it. The coolant
temperature gauge
shows
avalue above
248 ‡(120 †). The coolant level is too low. The coolant is too hot and the engine
is no longer being cooled sufficiently.
X
Stop as soon as possible and allow the engine and the coolant
to cool down.
X Check the coolant level (Y page 308). Observe the warning
notes as you do so and add coolant if necessary. 154

Parking brake
G
WARNING
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
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 turninga gain.G
WARNING
If you leave children unsupervised in the
vehicle, they could set it in motion by, for
example:
R releasing the parking brake
R shifting the automatic transmission out of
the parking position P
R startingt he engine.
They could also operate the vehicle's
equipment. There is arisk of an accident and
injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle. If you brake the vehicle with the parking
brake, the brake lamps will not light up. X
To apply: depress parking brake 0010firmly.

Braking
Important safety notes G
WARNING
If yo ushift down on aslipper yroads urface in
an attempt to increas ethe engine's braking
effect,t he drive wheels could lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine
braking on aslippery road surface.
Downhill gradients !
On long and steep gradients, you must
reduce the load on the brakes by shifting
early to alower gear. This allowsy ou to take
advantage of the engine braking effect and
helps avoid overheating and excessive
wear of the brakes.
When you take advantage of the engine
braking effect,ad rive wheel may not turn
for some time, e.g. on aslippery road
surface. This could cause damage to the
drive train. This type of damage is not
covered by the Mercedes-Ben zwarranty.
Do no tdepress the brake pedal continuously
while the vehicle is in motion ,e.g. causing the
brakes to rub by constantly applying light
pressure to the pedal. This results in
excessive and premature wear to the brake
pads.
On long and steep downhill gradients, you
must select shift range 1,2or 3in good time.
This is especially important if the vehicle is
laden.
Heavy and light loads G
WARNING
If you rest your foot on the brake pedal while
driving, the brakin gsystem can overheat .This
increases the stopping distance and can even
cause the braking system to fail. There is a
risk of an accident. Never use the brake pedal as
afootrest .Never
depress the brake pedal and the accelerator
pedal at the same time.
! Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If the brakes have been subjected to aheavy
load, do not stop the vehicle immediately, but
drive on for ashort while. This allows the
airflow to cool the brakes more quickly.
Wet roads If you have driven for
along time in heavy rain
without braking ,there may be adelayed
reaction from the brakes when braking for the
first time. This may also occur after the
vehicle has been washed or driven through
deep water.
You have to depress the brake pedal more
firmly. Maintain agreater distanc efrom the
vehicle in front.
After driving on awet road or having the
vehicle washed, brake firmly while paying
attention to the traffic conditions. This will
warm up the brake discs, thereby drying them
more quickly and protecting them against
corrosion.
Limited braking performance on salt-
treated roads If you drive on salted roads,
alayer of salt
residue may form on the brake discs and
brake pads. This can result in asignificantly
longer braking distance.
R Brak eoccasionally to remove any possible
salt residue. Make sure that you do not
endanger other road users when doing so.
R Carefully depress the brake pedal and the
beginnin gand end of ajourney.
R Maintain agreater distanc etothe vehicle
ahead. 172

Servicing the brakes
!
If the red brake warning lamp lights up in
the instrumen tcluster and you hear a
warnin gtonew hile the engine is running,
the brak efluid level may be too low.
Observe additional warnin gmessages in
the multifunction display.
The brak efluid level may be too low due to
brak epad wear or leakin gbrak elines.
Have the brak esystem checked
immediately. This work should be carried
out at aqualified specialist workshop.
! Vehicles with 4MATIC: function or
performanc etests may only be carried out
on a2 -axle dynamometer. If you are
planning to have the vehicle tested on such
ad ynamometer, contac tanauthorized
Mercedes-Ben zCenter to obtain further
information first. Otherwise, you could
damage the drive train or the brak esystem.

AMG high-performance and ceramic
brakes The high-performance brake system is
installed only on the CLS 63 AMG.
The AMG brake systems are designed for
heavy loads. This may lead to noise when
braking. This will depend on:

Speed
R Braking force
R Environmental conditions, such as
temperature and humidity
The wear of individualc omponentsofthe
brake system, such as the brake pads/linings
or brake discs, depends on the individual
driving style and operating conditions.
For this reason, it is impossibletos tate a

sensor system. DISTRONIC PLUS brakes
automaticallysot hat the set speed is not
exceeded.
Change into alower gear in good time on long
and steep downhill gradients. This is
especially important if the vehicle is laden. By
doing so, you will make use of the braking
effect of the engine. This relieves the load on
the brake system and prevents the brakes
from overheating and wearing too quickly.
If DISTRONIC PLUS detects that there is arisk
of ac ollision, you will be warned visually and
acoustically.D ISTRONIC PLUS cannot
prevent acollision without your intervention.
An intermittent warning tone will then sound
and the distance warning lamp will light up in
the instrument cluster. Brake immediately in
order to increase the distance to the vehicle
in front or take evasive action provided it is
safe to do so.
For DISTRONIC PLUS to assist you, the radar
sensor system must be operational.
If there is no vehicle in front,D ISTRONIC
PLUS operates in the same way as cruise
control in the speed range between 20 mph
(Canada: 30 km/h) and 120 mph (Canada:
200 km/h). If avehicle is driving in front of
you, it operates in the speed range between
0m ph (0 km/h) and 120 mph (Canada:
200 km/h).
Do not use DISTRONIC PLUS while driving on
roads with steep gradients.
As DISTRONIC PLUS transmits radar waves,
it can resemble the radar detectors of the
responsible authorities. You can refer to the
relevant chapter in the Operator's Manual if
questions are asked aboutt his.
