This is like four wheel drive, but there is no separate
lever or switch to engage or disengage the front axle.
It is fully automatic, and adjusts itself as needed for
road conditions.
You may experience a brief vehicle vibration upon
acceleration when driving in slippery conditions. This is
normal and is an indication that the all
system is functioning properly.

Tilt Wheel (If Equipped)
A tilt steering wheel allows you to adjust the steering
wheel before you drive.
You can also raise it to the highest level to give your
legs more room when you exit and enter the vehicle.
To tilt the wheel, hold the steering wheel and pull the
lever. Move the steering wheel to a comfortable level,
then release the lever to lock the wheel in place.
