USING THE 2WD/4WD
SWITCH
(for versions/markets, where provided)
This 4WD system enables you to select the
driving mode according to the driving con-
ditions by operating the 2WD/4WD
switch. With this feature, you can select 3
mode positions, “2WD”, “4WD AUTO”
and “4WD LOCK” by operating the 2WD/
4WD switch even when the vehicle is mov-
ing, provided the front wheels are in the
straight ahead position.
DESCRIPTION OF 3 MODE 4 X 4
SYSTEM POSITIONS
2WD
In this position, engine power is supplied
to the front axle only. Use this position
for normal driving (on dry, hard surfaces).
4WD AUTO
In this position, engine power is supplied
to the front and rear axles at normal
speed, providing greater traction than 2-
wheel drive. Use this position for driving
on paved roads or on slippery roads (icy,
snow-covered, muddy, etc.).In the AUTO mode, the 4WD controller
judges the driving conditions using signals
from sensors.
When slipping of the front wheels is de-
tected, the electronically controlled cou-
pling supplies optimum driving force to the
rear wheels. This function improves dri-
ving stability and running through perfor-
mance on rough roads and stabilizes dri-
ving performance even on a snow covered
up- hill road or the like.
Also, during normal driving on paved
roads, torque distribution to the rear
wheels is reduced to achieve the nearly
front wheel drive condition, thereby fuel
consumption is improved.

4WD LOCK
In this position, engine power is supplied
to the front and rear axles at reduced
speed. Use this position when it is hard to
start off in the “4WD AUTO” mode such
as in mud, sand or on snow.
NOTE
Avoid operating your vehicle in the
“4WD LOCK” on wet pavement as
much as possible. Operating your vehi-
cle in the “4WD LOCK” on wet pave-
ment may cause severe damage to the
drive train.
As the vehicle speed increases, the
“4WD LOCK” mode is automatically
canceled and the “4WD AUTO” mode
is selected.
When the ignition switch is turned to
the “OFF” position, the “4WD LOCK”
mode is canceled.

❒Insert the new wheel to the wheel
hanger. Install the wheel bolts to bolt
holes other than the position of wheel
hanger with their cone shaped end fac-
ing the wheel. Tighten each bolt snug-
ly by hand until the wheel is securely
seated on the hub.
❒Remove the wheel hanger and install a
wheel bolt. CHANGING WHEELS
To change a wheel, use the following pro-
cedure:
❒Remove the jack, tools and spare wheel
from the vehicle.
❒Loosen, but do not remove the wheel
bolts.
❒Jack up the vehicle (follow the jacking
instructions in the “EMERGENCY SER-
VICE” section).
❒Remove the wheel bolts and wheel.
❒Before installing the new wheel, clean
any mud or dirt off from the surface of
the wheel and hub with a clean cloth.
Clean the hub carefully; it may be hot
from driving.
❒Tighten the wheel hanger (1) in one of
the bolt holes on the wheel hub.
IMPORTANT Do not tighten the wheel
hanger too hard since the wheel hanger
can be damaged.

– Be sure to shift into “P”
(Park) for an automatic
transaxle vehicle, or into “R” (Reverse)
for a manual transaxle vehicle when
you jack up the vehicle.
– Never jack up the vehicle with the
transaxle in “N” (Neutral). Other-
wise, unstable jack may cause an ac-
cident.
WARNING
Tightening torque for wheel bolt
85 Nm (8.5 kgm, 61.5 lb-ft)
❒Lower the jack and fully tighten the
bolts in a crisscross fashion with a
wrench as shown in the illustration.

Use genuine wheel bolts and
tighten them to the specified
torque as soon as possible after chang-
ing wheels. Incorrect wheel bolts or im-
properly tightened wheel bolts may
come loose or fall off, which can result
in an accident. If you do not have a
torque wrench, have the wheel bolt
torque checked by an authorized Fiat
Dealership.
