Rear Axle
When to Check Lubricant
It is not necessary to regularly
check rear axle fluid unless a leak is
suspected or an unusual noise is
heard. A fluid loss could indicate a
problem. Have it inspected and
repaired.
How to Check Lubricant
To get an accurate reading, the
vehicle should be on a level
surface.The fluid level should be at or within
13 mm (0.5 in) of the bottom of the
fill plug hole threads. If it is at this
level, no additional fluid is needed.
If the fluid level is below 13 mm
(0.5 in), add fluid until it is above
this level.
What to Use
To add lubricant when the level is
low or to completely refill after
draining, see
Recommended Fluids
and Lubricants 0308. Then fill to
within 13 mm (0.5 in) of the bottom
of the fill plug hole threads with the
required lubricant.
Starter Switch Check

injured. 1. Before starting this check, be
sure there is enough room
around the vehicle.
2. Firmly apply both the parking brake and the regular brake.
See Electric Parking Brake

Do not use the accelerator
pedal, and be ready to turn off
the engine immediately if it

3. For automatic transmission vehicles, try to start the engine
in each gear. The vehicle
should start only in P (Park) or
N (Neutral). If the vehicle starts
in any other position, contact
your dealer for service.
For manual transmission
vehicles, put the shift lever in
Neutral, push the clutch pedal
down halfway, and try to start
the engine. The vehicle should
start only when the clutch
pedal is pushed down all the
way to the floor. If the vehicle
starts when the clutch pedal is
not pushed all the way down,
contact your dealer for service.
