Service Vehicle Soon Message
United States Canada
This light will come on if your vehicle has certain
non
-emission related problems.
For example, if the entire electrical system fails to send
and receive messages from the vehicle's components,
this message will come on.
These problems may not be obvious and may affect
vehicle performance or durability. Consult a qualified
dealership for necessary repairs to maintain top
vehicle performance.
AWD Disable Warning Message (Option)
United States Canada
You will receive this message when there is a spare tire
on the vehicle, when the anti
-lock brake system warning
light comes on, or when the rear differential fluid is in
an overtemp condition. The message will go out when
the differential fluid cools.
The all
-wheel-drive system will be disabled until the
compact spare tire is replaced by a full
-size tire. If the
warning message is still on after putting on the full
-size
tire, you need to reset the warning message. To reset the
warning message, turn the ignition to OFF then to ON.
If the message stays on, see your dealer right away. See
ªAll
-Wheel Driveº in the Index for more information.

When to Check and Change Lubricant
Refer to the Maintenance Schedule to determine how
often to check the lubricant and when to change it.
See ªScheduled Maintenance Servicesº in the Index.
How to Check Lubricant
To get an accurate reading, the vehicle should be on a
level surface.
If the level is below the bottom of the filler plug hole,
you'll need to add some lubricant. Add enough lubricant
to raise the level to the bottom of the filler plug hole. A
fluid loss could indicate a problem; check and have it
repaired, if needed.
What to Use
Refer to the Maintenance Schedule to determine what
kind of lubricant to use. See ªRecommended Fluids and
Lubricantsº in the Index.

7-22 Throttle System Inspection
Inspect the throttle system for interference or binding,
and for damaged or missing parts. Replace parts as
needed. Replace any components that have high effort
or excessive wear. Do not lubricate accelerator and
cruise control cables.
Transfer Case (Power Transfer Unit) and
Carrier Assembly - Differential (Rear Drive
Module) All-Wheel Drive Inspection
Every 12 months or at engine oil change intervals,
check rear differential and transfer case and add
lubricant when necessary. A fluid loss could indicate a
problem; check and have it repaired, if needed. Check
vent hoses at transfer case and differential for kinks and
proper installation.
Brake System Inspection
Inspect the complete system. Inspect brake lines and
hoses for proper hook
-up, binding, leaks, cracks,
chafing, etc. Inspect disc brake pads for wear and rotors
for surface condition. For vehicles with rear drum
brakes, also inspect drum brake linings for wear and
cracks. Inspect other brake parts, including drums,
wheel cylinders, calipers, parking brake, etc. Check
parking brake adjustment. You may need to have your
brakes inspected more often if your driving habits or
conditions result in frequent braking.
