di
s
connection status of the system:
●

Sport mode, only by means of Easy Connect.
Brake system*
Situations in which the warning lamp lights
up
●
the brake fluid level is too low

›
›
page 208.
●
there is a fault in the brake system.
This warning lamp can light up together with
the ABS system warning lamp.
WARNING
●
If the brak
e warning lamp does not go out
or if it lights up when driving, the brake fluid
level in the reservoir is too low so there is a
risk of an accident ››› page 208, Brake fluid.
Stop the vehicle and do not drive on. Obtain
technical assistance.
●
If the brake warning lamp lights up to-
gether with the ABS lamp this could be
due to an ABS fault. 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 technical
assistance.
Cruise speed (cruise control system)*
The warning lamp comes
on when the
cruise control system is switched on. For fur-
ther information on the cruise control system
please see ›››

on.
The tyre monitoring lamp* compares wheel
r
ev
o
lutions and with it, using the ESC, the
wheel diameter of each wheel. If the diame-
ter of a wheel changes, the tyre control lamp
lights up. The wheel diameter 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 steep slopes).
●
The vehicle is fitted with snow chains.
●
The temporary spare wheel is fitted.
●
The wheel on one axle is changed.
Tyre pressure adjustment
On adjusting tyre pressure or changing one
or more wheels, the ››› Fig. 124 button must
be kept pressed down, with the ignition on,
until an acoustic signal is heard.
Store the new tyre pressure in the Easy Con-
nect system with the button

If the wheels are under excessive load (for ex-
ample, 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 monitor system button is pressed down,
the new tyre pressures are confirmed.
The tyre pressure control lamp lights up
If the tyre pressure of a wheel is much lower
than the value set by the driver, then the tyre
pressure control lamp ›››
will light up.
