Alternator 
This warning lamp signals a fault in the alternator.
The warning lamp  lights up when the ignition is switched on. It should
go out when the engine has started running.
If the warning lamp  lights up while driving, the alternator is no longer
charging the battery. You should immediately drive to the nearest special-
ised workshop.
You should avoid using electrical equipment that is not absolutely necessa-
ry because this will drain the battery.

Worn brake pads 
If the  symbol lights up, have the front brake pads (and, for safety rea-
sons, the rear pads as well) inspected by a specialised workshop.

Tyre pressure 
The tyre pressure control system controls the tyre speed and
the frequency spectrum of each tyre.

 compares wheel revolutions and with this informa-
tion, the diameter of each wheel using the ESC (ESP) sensors. If the diame-
ter of a wheel changes, the tyre warning lamp  lights up. The wheel diam-
eter changes when:
● Tyre pressure is insufficient.
● The tyre structure is damaged.
● The vehicle is unbalanced because of a load.
● The wheels of one axle are under more pressure (for example, driving
with a trailer or on extreme slopes).
● The vehicle is fitted with snow chains.

● The temporary spare wheel is fitted.
● The wheel on one axle is changed.
Tyre pressure adjustment
Following the modification to tyre pressure or after changing one or more
wheels, the button 
⇒ fig. 50
 must be kept pressed while the ignition is on
until an acoustic signal is heard and the warning lamp goes out.
If the wheels are under excessive load (for example, driving with a trailer or
heavy load), the tyre pressure must be increased to the recommended value
for a full load (see the sticker on the inside of the fuel flap). If the tyre moni-
tor system button is pressed down, the new tyre pressures are confirmed.
The tyre pressure warning lamp  lights up
If the tyre pressure of one or more wheels is much lower than the value set
by the driver, the tyre control warning lamp lights up 
⇒  .
The tyre pressure warning lamp  flashes
If the tyre pressure warning lamp flashes, this indicates a fault. Go to the
nearest specialist workshop.
WARNING
●
When the tyre pressure warning lamp lights up, reduce speed imme-
diately and avoid any sudden manoeuvre or braking. Stop when possible,
and check the tyre pressure and status.
●
The driver is responsible for maintaining correct tyre pressures. For
this reason, tyre pressure must be regularly checked.
●
Under certain circumstances (for example, when driving in a sports-
like manner, in winter conditions or on a dirt track) the tyre warning lamp
may light up or function incorrectly.
Note
If the battery is disconnected, the yellow warning lamp  lights up after
turning the ignition on. This should turn off after a brief journey.

Brake system* 
This warning lamp lights up if the brake fluid level is too low
or if there is a fault in the system.
This warning lamp  lights up if
● the brake fluid level is too low 
⇒ page 229.
The instrument panel displays the following message

.
● there is a fault in the brake system.
The instrument panel displays the following message

WARNING
●
Before opening the bonnet, read and observe the warnings on
⇒ page 217.
●
If the brake warning lamp does not go out, or if it lights up when driv-
ing, the brake fluid level 
⇒ page 229, Brake fluid in the reservoir is too
low. Risk of accident. Stop the vehicle and do not drive on. Obtain techni-
cal assistance.
●
If the brake warning lamp  lights up together with the ABS warning
lamp , the control function of the ABS could be out of action. This could
cause the rear wheels to lock quickly when you brake. This could cause
the rear to break away. Risk of skidding. Stop the vehicle and seek tech-
nical assistance.

Handbrake 
This lamp lights up when the handbrake is applied.
If you drive faster than 6 km/h with the handbrake on, the following mes-
sage will appear on the instrument panel display
1)
: 
HANDBRAKE ON.
 You will
also hear an acoustic warning signal 
⇒ page 173.

Bulb defect 
The warning lamp lights up when a bulb in the vehicle's ex-
terior lighting is defective.
The warning lamp  lights up when a bulb in the vehicle's exterior lighting
(e.g. left-hand main beam) is defective.
The instrument panel displays the following message
1)
: 
LEFT FULL BEAM
FAULTY
.

Engine oil pressure 
If this warning lamp is red it indicates that the engine oil
pressure is too low.
If this warning symbol starts to flash, and is accompanied by three 
audible
warnings, switch off the engine and check the oil level. If necessary, add
more oil 
⇒ page 220.
The instrument panel displays the following message
1)
: 
STOP ENGINE OIL
PRESSURE INSTRUCTION MANUAL
.
If the symbol flashes although the oil level is correct, do not drive on. The
engine must not even run at idle speed. Obtain technical assistance.
Checking the oil level 
If the warning lamp is yellow  the engine oil level should be checked as
soon as possible. Top up the oil 
⇒ page 222 at the next opportunity.
Oil level sensor faulty* 
If the  yellow warning lamp flashes, take the vehicle to a specialised
workshop to have the oil level sensor checked. Until then it is advisable to
check the oil level every time you refuel.
