dealer check your system. Turn the INT LIGHTS switch located to the right
of
your headlight switch
to
dim your transfer case indicator light when your
headlights
or
parking lights are on. This will also cause your instrument
panel lights to dim.
2HI - This setting is for driving in most street and highway situations.
Your front axle is not engaged in two-wheel drive.
4HI
-
This setting engages your front axle to help drive your vehicle. Use
4HI when you need extra traction, such as on snowy or icy roads, or in most
off-road situations.
N SET PARK BRAKE
-
Shift to this neutral setting only when your
vehicle needs to be towed.
4LO
-
This setting also engages your front axle to give you extra traction
and provides extra gear reduction. You may never need 4LO. It sends the
maximum power to all four wheels. You might choose 4LO if you were
driving off-road in sand, mud, or deep snow and climbing or descending
steep hills.
You can shift from 2HI to 4HI or from 4HI to 2HI while the vehicle is
moving. Do not press the transfer case shift lever button when shifting from
2HI to 4HI or from 4HI to 2HI. Your front axle will engage faster if you
take your foot off of the accelerator for a few seconds after you shift.
To shift your transfer case into N SET PARK BRAKE:
1. Stop the vehicle and shift your transmission into NEUTRAL (N).
2. Set the parking brake. Your vehicle can roll unless the brakes are
applied.
3. Pull the transfer case shift lever into N SET PARK BRAKE.
To shift into or out of 4LO:
1. The vehicle must be stopped or moving less than 3 mph (4.8 km/h)
with the transmission in NEUTRAL (N) for an automatic transmission
or the clutch pedal depressed with a manual transmission.
2. Press the transfer case shift button and shift in one continuous motion.
Don't pause in N SET PARK BRAKE as you shift into or out of 4L0, or
your gears could clash.
Remember that driving in 4HI or 4LO may reduce fuel economy. Also,
driving in four-wheel drive on dry pavement could cause your tires to wear
faster and make your transfer case harder to shift and reduce powertrain
longevity.
