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 settingis for driving in most street and highway situations. Your front axleis not engaged in two-wheel drive. 4HI - This setting engages your front axle to help drive your vehicle. Use 4HI when you needextra 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 fourwheels. 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 from4HI to 2HI. Your front axle will engage faster if you take your foot off of theaccelerator for afew 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 youshift 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. 2-31
