and warning/indicator lamps
Fuel gauge
The gauge @ only works when the ignition is
switched on. If there is less than 7 litres of fuel in
the tank, the LED at the bottom of the dial will
light up in red and the indicator lamp tD will ap­
pear c:::>page 16. The LED at the bottom of the
dial will flash in red if the fuel level is very low.
The tank capacity of your vehicle is given in the
Technical data section c:::> page 258.
CD CAUTION
Never run the tank completely dry. If there is
an irregular fuel supply, misfiring can occur.
Unburnt fuel can then enter the exhaust sys­
tem. This can lead to overheating and dam­
age to the catalytic converter.
Warning and indicator
lamps
Description
The warning and indicator lamps light up or flash
in the instrument cluster. Their purpose is to in­
dicate functions or faults.
Some of the warning and indicator lamps may be
accompanied by a driver message and a warning
tone. The warning/indicator lamps and driver
messages on the display can be masked by fur­
ther displays. To display a warning or message
again, use the controls on the multi-function
steering wheel to select the display tab for warn­
ing/indicator lamps and messages c:::> page 18.
If several malfunctions have occurred, you can
use the thumbwheel to scroll through them on
the display.
Some of the warning lamps may be displayed in
different colours.
Overview

lamp DJ light up together with the brake warn­
ing lamp .
and this driver message appears,
the ABS, ESC and brake force distribution sys­
tems have failed ¢ A. •
Parking brake: fault. See owner's manual
- If the warning lamp and the message appear
after you switch on the ignition when the ve­
hicle is stationary, please check whether you
can release the parking brake. If the parking
brake cannot be released you should obtain
professional assistance. If the parking brake
can be released but the warning lamp/message
still appears, drive to a qualified workshop
without delay and have the fault rectified.

tance.
A WARNING
- Before opening the bonnet and checking the
brake fluid level, observe the warning infor­
mation on ¢ page 220, Working on compo­
nents in the engine compartment.
- If the brake warning lamp does not go out,

id level in the reservoir is too low -this may
cause an increased accident risk. Stop the
vehicle and do not drive on. Obtain profes­
sional assistance.
- If the brake warning lamp lights up togeth­
er with the ABS indicator lamp and the ESC
indicator lamp, this can mean that the con­
trol function of the ESC/ABS is not working.

The electro-mechanical parking brake replaces
the handbrake.
Fig. 74 Centre console: Parking brake
� To apply the parking brake, pull the switch
� Fig. 74. The warning Lamps.
in the button
and in the infotainment display will light up.
� To release the parking brake, press the brake or

Your vehicle is equipped with an electro-mechani­
cal parking brake. The parking brake replaces the
conventional handbrake, and is mainly intended
to prevent the vehicle from rolling away acciden­
tally.
66 However,
the electro-mechanical parking brake
also offers a number of convenience and safety
features in addition to the functions of a normal
handbrake.
When driving away
- The parking brake auto release function relea­
ses the parking brake automatically when you
wish to start moving ¢ page 67, Driving away
from a standstill.
- When
driving away on a gradient, the parking
brake auto release function prevents the vehicle
from rolling back unintentionally. The braking
force of the parking brake is only released when
there is enough power at the wheels to make
the vehicle move in the desired direction.
Emergency braking function
An emergency braking function enables you to
stop the vehicle even if the conventional foot
brake should fail to work ¢ page 68, Emergen­
cy braking function.
Warning lamps - The warning Lamps.
on the display and in the
switch Light up when the parking brake is ap­
plied with the ignition switched on.
- The warning Lamps.
on the display and in the
switch Light up for approximately 20 seconds
when the parking brake is applied with the igni­
tion switched off.
_& WARNING
- The accelerator pedal must on no account
be pressed inadvertently when a gear is en­
gaged and the engine is running with the ve­
hicle stationary. The vehicle could otherwise
start moving immediately and possibly
cause an accident.
- It is not possible to apply the parking brake
if the electrical power supply fails. In this
case, park the vehicle on a Level surface and
select 1st gear (manual gearbox) or move
the selector Lever to position P (automatic
gearbox) to prevent it from rolling. Obtain
professional assistance.

Note
- The parking brake can be applied at any
time -even when the ignition is switched
off. However, the ignition must be switched
on and the brake pedal pressed before the
parking brake can be released.
- The parking brake is applied automatically if
the driver's door is opened while the igni­
tion is on. This is to prevent the vehicle from
accidentally rolling away.
-Any slight noise which may be heard when
the parking brake is applied or released is
quite normal and no cause for concern.
- The parking brake runs an automatic test cy­
cle at regular intervals when the vehicle is
parked. This may cause a slight noise, which
is normal.
- If the warning lamp. appears, there may
be a parking brake malfunction ¢ page 11.
- If the electrical power supply fails, it is not
possible to release the parking brake (if it
was applied) or to apply the parking brake
(if it was released) ¢ .&.. Obtain professional
assistance.
Parking the car
.,. Press the brake pedal to bring the vehicle to a
stop.
.,. To apply the parking brake, pull the switch
¢ page 66, Fig. 74.
.,. Vehicles with automatic gearbox: Move these-
lector lever to position P.

A WARNING
- Always take the key with you when leaving
your vehicle -even if you only intend to be
gone for a short time. This is especially im­
portant if children are left in the car. They
might otherwise be able to start the engine,
release the parking brake or use power-op- Driving
erated equipment such as the electric win­
dows -this could lead to injuries.
- Do not leave anyone (especially children) in
the vehicle when it is locked. Locked doors
could delay assistance in an emergency, po­
tentially putting lives at risk.
Driving away from a standstill
The parking brake auto release function releases
the parking brake automatically when you wish

Releasing the parking brake when driving
away
Important: The driver's door must be closed and
the driver's seat belt must be buckled.
.,. Press the accelerator in the normal way: the
parking brake will be released automatically
and the vehicle will start moving.
You can apply the parking brake when stopping at
traffic lights, etc. You do not then have to hold
the car with the brake pedal, as the parking brake
will stop it creeping forward while a gear is en­
gaged in the automatic transmission. When you
drive off in the normal way, the parking brake will
be released automatically and the vehicle will
start moving.
Driving away on a slope
When driving away on a gradient, the parking
brake auto release function prevents the vehicle
from rolling back unintentionally. The braking
force of the parking brake is only released when
there is enough power at the wheels to make the
vehicle move in the desired direction.
@ Note
For safety reasons the parking brake will only
release automatically if the driver's seat belt
is engaged in its buckle and the driver's door
is closed .

Emergency braking function
This feature enables you to stop the vehicle if the
main brake system should fail or if the pedal is
obstructed.
� To stop the vehicle with the parking brake in an
emergency, pull and hold the parking brake
switch q page 66, Fig. 74.
� The brakes will be released immediately if you
release the switch or press down the accelera­
tor.
If you pull out and hold the parking brake switch
at a road speed above about 3 km/h, this will ini­
tiate an emergency brake application. The brakes
are then applied hydraulically at all four wheels.
The effect is similar to heavy braking q .&. .
To prevent the emergency braking function from
being used accidentally, a warning buzzer sounds
when the switch is operated. The brakes are re­
leased immediately when you release the switch
or press down the accelerator.
A WARNING
You should only use the emergency braking
function in a real emergency, for example if
the brake system were to fail or if the brake
pedal were to be obstructed. If you use the
emergency braking function by activating the
parking brake switch, this has the same effect
as heavy braking. Please remember that the
ESC (and the integrated ABS, EDL and traction
control functions) is still subject to certain
physical limits. In a corner or in bad road or
weather conditions an emergency stop can
cause the vehicle to skid or lose steering con­
trol.

assist
Applies to vehicles: with hold assist
Fig. 75 Section of centre console: Button for hold assist
The hold assist helps the driver if the vehicle is
stationary for a long period or very often, for in­
stance at traffic lights, on steep gradients or in
stop-and-go traffic.
Switching on the hold assist
Important: The driver's door must be closed, the
driver's seat belt buckled and the engine running.
� Press the button q Fig. 75 in the centre console
to switch on the hold assist function. The LED
in the button will light up.
Stopping with the hold assist
� Once it detects that the vehicle has stopped,
the hold assist keeps the vehicle stationary. You
can now take your foot off the brake pedal.
� Drive off in the normal way: the brake will be
released automatically and the vehicle will start
moving.
Switching off the hold assist
� Press the button to switch off the hold assist
function. The LED in the button will go out.
In certain situations, the hold assist transfers the
job of holding the vehicle to the parking brake. As
soon as the parking brake is holding the vehicle
still, the warning Lamp. appears in the instru­
ment cluster.
A WARNING
The intelligent technology in the hold assist
function cannot defy the Laws of physics. Do
not let the extra convenience afforded by the
