Brake” in the Index if necessary) and the
regular brake.
NOTE: Do not use the accelerator pedal, and be
ready to turn off the engine immediately
if it starts.
3. Try to start the engine in each gear. The starter
should work only
in PARK (P) or NEUTRAL (N).
If the starter works in any other position, your
vehicle needs service.
Brake-Transmission Shift Interlock (BTSI) Check

Steering, Suspension and Front Drive Axle
Boot and Seal Inspection
Inspect the front and rear suspension and steering
system for damaged, loose or missing parts, signs of
wear or lack
of lubrication. Inspect the power steering
lines and hoses for proper hook-up, binding, leaks,
cracks, chafing, etc. Clean and
then inspect the drive
axle boot seals for damage, tears or leakage. Replace
seals if necessary.
Exhaust System Inspection
Inspect the complete exhaust system. Inspect the body
near the exhaust system. Look for broken, damaged,
missing or out-of-position parts
as well as open seams,
holes, loose connections or other conditions which could
cause
a heat build-up in the floor pan or could let
exhaust fumes into the vehicle. See “Engine Exhaust’’ in
the Index.
Engine Cooling System Inspection
Inspect the hoses and have them replaced if they are
cracked, swollen
or deteriorated. Inspect all pipes,
fittings and clamps; replace as needed. Clean the outside
of the radiator and air conditioning condenser.
To help
ensure proper operation, a pressure test of the cooling
system and pressure cap is recommended at least once
a year.

and for damaged
or missing parts. Replace parts as
needed. Replace any components that have high effort
or excessive wear.

cruise control cables.
Drive Axle Service
Check readfront axle fluid level and add as needed.
Check constant velocity joints and axle seals for leaking.
Transfer Case (All-Wheel Drive) Inspection
Every 12 months or at oil change intervals, check
front axle and transfer case and add lubricant
when
necessary. Check vent hose at transfer case for kinks
and proper installation.
Brake System Inspection

hoses for proper hook-up, binding, leaks, cracks,
chafing, etc. Inspect disc brake pads for wear and rotors
for surface condition. Also inspect drum brake linings
for wear and cracks. Inspect other brake parts, including
drums, wheel cylinders, calipers, parking brake, etc.

your brakes inspected more often
if your driving habits
or conditions result
in frequent braking.
