After a cold engine is started, there may be a
brief period of increased noise because oil
pressure must first build up in the hydrau lic
valve adjusters . This is norma l and not a cause
for concern .
.&_ WARNING
-
-Never allow the engine to run in confined
spaces -danger of asphyxiation.
- Never turn off the engine until the vehi­
cle has come to a complete stop.
- Always take the key with you whenever
you leave your veh icle . Otherw ise, the
engine could be started or electrical
equ ipment such as the power windows
could be operated . This can lead to seri­
ous injury .
- Never leave children or persons requiring
assistance unattended in the vehicle . The
doors can be locked using the remote
tr an smitter, preventing people from es­
caping from the veh icle on their own in
the event of an emergency. Depending
on the time of year, peop le inside the ve­
hicle can be exposed to very high or very
low temperatures .

The stored speed and the green symbol
ll!j(i)~i4 (US model) I ill (Canadian model) are
shown in the display
c::> fig . 81. The display
may vary, depending on the type of display in
your vehicle. The indicator light
ll!;(i)~i4 (US model)/ ii (Canadian model) will
also light up in the instrument cluster .
The speed is kept constant by modifying en­
gine power or through an active brake inter­
vention.
A WARNING
-- Always pay attent ion to the traffic
around you when the cruise control is in
operation. You are always responsible for
your speed and the distance between
your veh icle and other vehicles.
- For reasons of safety, cruise control
should not be used in t he city, in stop­
and-go traffic, on twisting roads and
when road conditions are poor (such as
ice, fog, gravel, heavy rain and hydro­
p laning) -risk of accident .
- Turn off the cruise control temporarily
when entering turn lanes, highway exit
lanes or in constr uction zones .
- Please note that inadve rtently "resting"
your foot on the accelerator pedal causes the cruise control not to brake. This is
because the cruise control is overridden
by the driver's acceleration.
- If a brake system malfunction such as
overheating occurs when the cruise con­
trol system is switched on, the braking
function in the system may be sw itched
off. The other cruise control functions re­
main active as long as the indicator light
lij;(l)~i4 (US models) ;ill (Canadian mod­
els) is on.
(D Tips
-Veh icles with manual transmiss ion: You
can attain the set speed only if the gear
th at is cur rently engaged will allow it, or
if it does not tax the engine and allows it
to run smoothly. Therefore shift into a
higher or lower gear in a timely manner.
- Th e brake lights illuminate as soon as
the brakes apply automatically.
