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 audible warning 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 control 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 control lamp flashes
If the tyre pressure control lamp flashes, this indicates a fault. Go to the
nearest specialised workshop.
WARNING
● When the tyre pressure control lamp lights up, reduce speed immedi-
ately 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 control 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. Bulb defect

WARNING
● Before opening the bonnet, read and observe the warnings on
⇒ page 222.
● If the brake warning lamp does not go out, or if it lights up when driv-
ing, the brake fluid level ⇒ page 234, 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 (4 mph) with the handbrake on, the following
message will appear on the instrument panel display 1)
: HANDBRAKE ON. You
will also hear an acoustic warning signal ⇒ page 180.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 225.
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. Do
not even run the engine 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 227 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.
Cruise speed (Cruise control)*
The warning lamp comes on when the cruise control system
is switched on.
The warning lamp lights up when the cruise control system is switched

Electronic Stability Control (ESC)* /
There are two control lamps for the electronic stability con-
trol. The lamp provides information concerning the func-
tion and the provides information on the disconnection
status
Both lamps come on together when the ignition is switched on and should
go out after approx. 2 seconds, which is how long the function check lasts.
This programme includes the ABS, EDL and ASR. This also includes the
brake assist system (BAS), automatic cleaning of the brake discs and the
trailer stability programme (TSP).
The warning lamp has the following functions:
● It flashes whilst driving when the ASR/ESC is activated.
● It will light up continuously if there is a fault in the ESC.
● As the ESC operates in conjunction with the ABS, it will also light up if a
fault should occur in the ABS.
If the ESC control lamp lights up and stays on after the engine is started,
this may mean that the control system has temporarily switched off the ESC.
In this case the ESC can be reactivated by switching the ignition off and
then on again. If the control lamp goes out, this means the system is fully
functional.
The lamp provides information about the disconnection status of the
system:
● It stays lit when the ASR is disconnected when pressing the switch.Differential lock fault (EDL)*The EDL operates along with the ABS in vehicles equipped
with the Electronic Stability Control (ESC)*
A malfunction in the EDL is indicated by the ABS control lamp . Take the
vehicle to a specialised workshop as soon as possible. For further informa-
tion on the EDL see ⇒ page 190, Electronic differential lock (EDL)*.
Traction control system (ASR)* /
The traction control system prevents the driven wheels from
spinning when the vehicle is accelerating
There are two warning lamps for the traction control system: and . Both
lamps come on together when the ignition is switched on and should go out
after approx. 2 seconds, which is how long the function check lasts.
The lamp has the following function:
● It flashes when the ASR is working if the vehicle is moving.
If the system is deactivated or if it has any fault, the warning lamp will re-
main lit. The warning lamp will also light up if a fault should occur in the
ABS because the ASR operates in conjunction with the ABS. For further in-
formation, see ⇒ page 187, Brakes
The lamp provides information about the disconnection status of the
system:
● It stays lit when the ASR is disconnected when pressing the ASR OFF
switch.
By pressing it again, the ASR function is reactivated and the warning lamp
switched off.

General information
The steering wheel includes a multifunction module from where it is possi-
ble to control the audio, telephone and radio navigation functions, and the
automatic gearbox*, without needing to distract the driver.
There are three versions of the multifunction module:
● Audio version, to control the available audio functions from the steering
wheel.
● Audio + Telephone version, to control the available audio functions and
the telephone system from the steering wheel.
Both versions may be used to control the Audio system (Radio, Audio CD,
mp3 CD, iPod 1)
/USB 1)
/SD 1)
) and the Radio navigation system, in which
case they also control the Navigation system.
● Version for automatic gearbox* ⇒ page 178.
