Driver information system
The service interval display determines when a service procedure is
needed for your vehicle . It operates in two stages:
• Service reminder : Before reaching a service event, this message
appears briefly when you switch on the ignition:
OIL CHANGE IN
1230 Ml (2000 KM) 150 DAYS.
• Service event: When the date for service is reached, the message
OIL CHANGE! appears. It is accompanied by an audible signal.
Display remaining distance
By briefly pulling the knob,@) ~ page 12 , fig. 2, the dis tance/time
remaining to the next service date is displayed with the ignition on.
The distance/ time remaining is updated every 300 miles (500 kml.
If the distance/time remaining is cal led up on new vehicles or after
service has been performed, the due date is always shown in the
display with
OIL CHANGE IN····· Ml (KMl··· DAYS within the first 300
miles (500 km).
To reset the displa y

On-Board Diagnostic system (OBD)
On-Board Diagnostics
Fig. 10 Locat ion of
Data Link Connector
( DLC )
On-Board Diagnostics monitors the components of your emission
control system . Each monitored component in your engine system
has been assigned a code. In case of a malfunction, the component
wi ll be identified and the fault stored as a code in the control
module memory.
The MIL light may also illuminate if there is a leak in the on -board
fuel vapor recovery system. If the light ill uminates after a refuelling,
stop the vehicle and make sure the fuel fi ller cap is properly closed
~ page 213.
In order to make an accurate diagnosis, the stored data can only be
displayed using special diagnostic equipment (generic scan tool for
OBD) . ...

Speed warning system
Overview
The speed warning system helps you to keep your driving
speed below a set speed limit.
Fi g. 18 D isplay: s pee d
w arn in g sys tem
The speed warning system warns the driver if he exceeds a previ­
ously stored maximum speed . A warning tone wi ll sound as soon as
the vehicle speed exceeds the set speed by about 3 mph (3 km/h). At
the same time, a warning symbol appears in the display=> fig. 18.
The speed warn ing system has
two warning thre shold s that func­
tion independent ly of each other and that have somewhat different
purposes :
Speed w arnin g 1 _ / ~ (C ana da mod els)
You can use speed warning 1 to set the max imum speed whi le you
are driving. This setting wi ll remain in effect until you turn off the
ign ition, assuming that you have not changed or reset the setting .
The speed warning symbo l / (Canada mode ls) in the warning 1
display appears when you exceed the maximum speed. It goes out
when the speed falls be low the stored maximum speed.
The speed warning symbol will also go out if the speed
exceeds the
stored maximum speed by more than about 25 mph (40 km/h) for at
least 10 seconds. The stored maximum speed is de leted . Setting speed warning 1
~ page 30.
S
peed w arning 2 I (Canada m odel s)
Storing warning 2 is recommended if you always want to be
reminded of a certain speed, for example when you are traveling in
a country that has a general maximum speed limit, or if you do not
want to exceed a specified speed for winter tires .
The speed warning 2 symbol, _;_._ (Canada models) appears in the
display when you exceed the stored speed limit. Unlike warning 1,
it wi ll not go out until the vehic le speed drops be low the stored
speed limit .
Setting speed warning 2
~ page 31 .
[ i ] Tips
Even though your vehicle is equipped with a speed warning system,
you should still watch the speedometer to make sure you are not
driving faster than the speed limit .•
Speed warning 1 : setting a speed limit
Warning threshold 1 is set by the button .
Storing the maximum speed
- Drive at the desired maximum speed.

• With the light switch at the O or ;:oo: position , only your front fog
lights remain turned on when it turns dark outside . Even though
your instruments appear well lit, the road ahead of you is not. The
light pattern provided by fog lights alone is not suffic ient for safe
driving in poor light or darknes s. Therefore:
• Always be aware of changes in outside light conditions while
you are driving. Respond in time to fading daylight by turning the

indicator lights ¢ or¢ in the instrument cluster => page 15 also
blink.
• After you have turned a corner, the turn signal switches off auto ­
matically.
• The high beam works only when the head lights are on. The indi­
cator light ~D in the instrument cluster ill uminates when the high
beams are on.
• The headlight flasher works only as long as you hold the lever -
even if there are no lights switched on. The ind icator light ~D in the
instrument cluster illuminates when you use the headlight flasher.

Warm and cold
Climate controls
Controls
The air conditioning automatically maintains the selected
temperature in the vehicleinterior throughout each
se ason.
F ig. 76 C limate contro ls
We recommend the following setting:
- Rotate the knob~ fig. 76@ to the right to switch on the
ai r conditioning.
- Set the temperature to 72 °F (22 °C).
- Press the !AUTO
j ~ fig. 76 button.
Con tro ls and eq uip­
ment
W arm and cold
Using the previously recommended setting is the quickest way to
achieve a comfortable climate in the vehicle. This setting should
therefore only be changed when personal comfort levels or certa in
circumstances require it.
The climate controls are a combination of automatic heating and
ventilation systems and a cooling system which dehumidifies and cools the air inside the vehic le .
The climate controls automatically maintain a temperature once it has been set. The temperature of the air from the vents, fan speed
(air volume) and air dist ribu tion are a lso automatically adjus ted . The
system also takes into account strong sunshine so that manual
adjus tment is not necessary. So in almost all cases,
a ut omatic mode
offers the best conditions for the comfort of the occupants at all
times of the year~
page 88.
Ple ase not e:
In cooling mode, relative humidity in the interior is reduced. This
prevents the windows from fogging up .
When relative humidity and temperatures outside are high,
conden ­
s ate
can drip from the air conditioning evaporator and form a pool
of water under the vehicle . This is normal and not an indication of a
leak!
When outside temperatures are low, the fan does no t switch to a
higher speed until the coolant has reached an adequate tempera­
ture, with the exception of t he defrost setting .
When accelerating at wide-open throttle, the air conditioning compressor is temporarily switched off to maintain fu ll engine
power.
In order to ensure engine cooling under extreme engine loads, the
compressor is switched off if coolant temperatures climb too high ...
