Driving your vehicle
- Changing lanes
When a vehicle changes lanes in
front of you, the FCA system may not
immediately detect the vehicle, espe-
cially if the vehicle changes lanes
abruptly. In this case, you must main-
tain a safe braking distance, and if
necessary, depress the brake pedal
to reduce your driving speed in order
to maintain a safe distance.When driving in stop-and-go traffic,
and a stopped vehicle in front of you
merges out of the lane, the FCA sys-
tem may not immediately detect the
new vehicle that is now in front of
you. In this case, you must maintain
a safe braking distance, and if nec-
essary, depress the brake pedal to
reduce your driving speed in order to
maintain a safe distance.
- Detecting the vehicle in front of you
If the vehicle in front of you has cargo
that extends rearward from the cab,
or when the vehicle in front of you
has higher ground clearance, addi-
tional special attention is required.
The FCA system may not be able to
detect the cargo extending from the
vehicle. In these instances, you must
maintain a safe braking distance
from the rearmost object, and if nec-
essary, depress the brake pedal to
reduce your driving speed in order to
maintain distance.

CRUISE CONTROL SYSTEM
The cruise control system allows you
to program the vehicle to maintain a
constant speed without depressing
the accelerator pedal.
This system is designed to function
above approximately 30 km/h (20
mph).
If the cruise control is left on,
(CRUISE indicator light in the instru-
ment cluster illuminated) the cruise
control can be switched on acciden-
tally. Keep the cruise control system
off (CRUISE indicator light OFF)
when the cruise control is not in use,
to avoid inadvertently setting a speed. Use the cruise control system only
when traveling on open highways in
good weather.
Do not use the cruise control when
driving in heavy or varying traffic, or
on slippery (rainy, icy or snow-cov-
ered) or winding roads or over 6%
up-hill or down-hill roads.
✽ ✽
NOTICE
• During normal cruise control oper-
ation, when the SET switch is acti-
vated or reactivated after applying
the brakes, the cruise control will
activate after approximately 3 sec-
onds. This delay is normal.
• To activate cruise control, depress the brake pedal at least once after
turning the ignition switch to the
ON position or starting the engine.
WARNING - Misuse of
Cruise Control
Do not use cruise control if the
traffic situation does not allow
you to drive safely at a constant
speed and with sufficient dis-
tance to the vehicle in front.

To decrease the cruising
speed:
Follow either of these procedures:
Move the lever down (to SET-) and
hold it. Your vehicle will gradually
slow down. Release the lever at the
speed you want to maintain.
Move the lever down (to SET-) and release it immediately. The cruising
speed will decrease by 10 km/h (5
mph) each time the lever is operat-
ed in this manner.
To temporarily accelerate with
the cruise control on:
If you want to speed up temporarily
when the cruise control is on,
depress the accelerator pedal.
Increased speed will not interfere
with the cruise control operation or
change the set speed.
To return to the set speed, take your
foot off the accelerator.
To cancel cruise control, do
one of the following:
Depress the brake pedal.
Shift into N (Neutral) with an Automatic transmission.
Press the CANCEL switch.
Decrease the vehicle speed lower than the memory speed by 20
km/h (12 mph).
Decrease the vehicle speed to less than approximately 25 km/h (15
mph).
