For easy entry and loading, your vehicle can be
lowered by pushing the key fob air suspension
lowering button two times. When key fob low-
ering is requested, the vehicle will send a series
of chirps and flashes to alert the customer that the opera-
tion has begun and will continue these alerts until it
successfully lowers.
The following conditions must be met for the vehicle to
lower remotely:
• The vehicle must not already be in Entry/Exit (Park)
ride height.
• The vehicle battery must be fully charged.
• All doors must be closed.
• The key fob must be out of the vehicle. Canceling Remote Lowering
Vehicle lowering can be cancelled at anytime. When vehicle
lowering is canceled, the vehicle will raise up to the next
defined level and lock out the remote lowering feature
until the ignition has been cycled ON/OFF.
To cancel vehicle lowering, push the key fob air suspension
lowering button one time during the lowering process.
When vehicle lowering is canceled, the horn will chirp two
times and the turn signal lamps will flash four times. Once
raising is completed, the horn will chirp one time.

Rotate the end of the lever upward, to the first detent past
the intermittent settings for low-speed wiper operation.
Rotate the end of the lever upward to the second detent
past the intermittent settings for high-speed wiper opera-
tion.
Intermittent Wiper System
The intermittent feature of this system was designed for
use when weather conditions make a single wiping cycle,
with a variable pause between cycles, desirable. For maxi-
mum delay between cycles, rotate the control knob upward
to the first detent.
The delay interval decreases as you rotate the knob until it
enters the low continual speed position. The delay can be
regulated from a maximum of about 18 seconds between
cycles, to a cycle every one second. The delay intervals will
double in duration when the vehicle speed is 10 mph
(16 km/h) or less.
Windshield Washers
To use the windshield washer, push the washer knob,
located on the end of the multifunction lever, inward to the
second detent. Washer fluid will be sprayed and the wiper
will operate for two to three cycles after the washer knob is
released from this position.If the washer knob is depressed while in the delay range,
the wiper will operate for several seconds after the washer
knob is released. It will then resume the intermittent
interval previously selected. If the washer knob is pushed
while in the off position, the wiper will turn on and cycle
approximately three times after the wash knob is released.
To prevent freeze-up of your windshield washer system in
cold weather, select a solution or mixture that meets or
exceeds the temperature range of your climate. This rating
information can be found on most washer fluid containers.
WARNING!
Sudden loss of visibility through the windshield could
lead to a collision. You might not see other vehicles or
other obstacles. To avoid sudden icing of the wind-
shield during freezing weather, warm the windshield
with the defroster before and during windshield
washer use.
