Chevrolet 2006 Automobile User Manual


 
4 m (Four-Wheel High): This setting engages your
front axle to help drive your vehicle. Use four-wheel high
when you need extra traction, such as on snowy or
icy roads, or in most off-road situations.
4
n (Four-Wheel Low): This setting also engages
your front axle to give you extra traction. You may never
need Four-Wheel Low. It sends the maximum power
to all four wheels. You might choose Four-Wheel Low if
you were driving off-road in sand, mud or deep snow
and while climbing or descending steep hills. When
operating in Four-Wheel Low, the gear ratio provides
additional torque when compared to Four-Wheel
High. The transmission gear shift feel will be
exaggerated.
Indicator lights in the switches show you which setting
you are in. The indicator lights will come on briefly when
you turn on the ignition and the last chosen setting
will stay on. If the lights do not come on, you should take
your vehicle in for service. An indicator light will flash
while shifting. Fast flashing means the conditions
were not met to make the desired shift, typically the
vehicle was going too fast, the automatic transmission
was not in neutral, or the clutch pedal was not fully
pressed. Slow flashing means the shift is in progress. It
will stay on when the shift is completed. If for some
reason the transfer cannot make a requested shift, it will
return to the last chosen setting.
Shifting from Two-Wheel High to
Four-Wheel High
Press and release the Four-Wheel High switch. This
can be done at any speed, and the front axle will lock
automatically with some delay.
Shifting from Four-Wheel High to
Two-Wheel High
Press and release the Two-Wheel High switch. This can
be done at any speed, and the front axle will unlock
automatically with some delay.
It is normal to hear and feel your vehicle’s transfer case
shift into Four-Wheel Low. If you shift with the vehicle
stopped, the indicator light may remain flashing slowly. It
may be necessary to shift the transmission momentarily
into REVERSE (R) and DRIVE (D), for an automatic
transmission, or REVERSE (R) and FIRST (1) for
a manual transmission to have the light stop flashing.
