Conserving I1 oils of proper viscosity.
The
“SH” or “SG” designation may be
shown alone or in combination with
others, such as “SH/CD,”
“SH, SG,

transmission shift linkage, parking
brake cable guides, underbody contact points and linkage. Lubricate the front

Transfer Case
WHAT TO DO
CAUTION: When you are doing this check, your vehicle could begin to move. You or others
could be injured and property could be damaged. Make sure ther\
e is room in front
of your
vehicle in case it begins
to roll. Be ready to apply the regular brake at once should the vehicle
begin to move.
Park on a fairly steep hill, with the vehicle facing downhill. Keeping your foot on the regular
brake, set the parking brake.
To check the parking brake: With the engine running and transmission in N (Neutral), slowly
remove foot pressure
from the regular brake pedal. Do this until the vehicle is held by the
parking brake only.
To check the P (Park) mechanism's holding ability: Shift to P (Park). Then release all brakes.
At least every spring, use plain water to flush any corrosive materials from the underbody. Take
care to clean thoroughly any areas where mud and other debris can collect.
Check rear/front differential fluid level and add as needed. Check constant velocity joints and
axle seals for leaking.
Check transfer case fluid level. Check vent hose at transfer case for ltinlts and proper installation.
More frequent lubrication may be required on heavy-duty off-road use.
A fluid loss may indicate a
problem. Have it inspected and repaired
at once.

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.
NOTE: A low brake fluid level can indicate worn disc brake pads which may need to be serviced.
Also, if the brake system warning light stays
on or comes on, something may be wrong with the
brake system. See the
Index under Brake System Warning Light. If your anti-lock brake system
warning light stays on or comes on, something may be wrong with the anti-lock brake system.
