Suspension
Check Front Suspension
1.Check condition of all ball joint dust covers,
including anti-roll bar links.
2.Check tightness of all accessible suspension
fixings including tie rods.
3.Check wheel bearings and suspension struts
for signs of excessive play or wear.
4.Check track rod ends for wear by attempting to
move the joint forwards and backwards, side to
side and up and down. No wear should be
apparent, if any is detected then the joint must
be replaced.
5.Check for signs of leakage from suspension
dampers.Check Rear Suspension
1.Check tightness of all accessible suspension
fixings including transverse links.
2.Check wheel bearings and suspension struts
for signs of excessive play or wear.
3.Check for signs of leakage from suspension
dampers.
Check Tow Bar Fixings
1.Check that the two vertical fixings are tightened
to a torque of 110 Nm (82 lbf.ft).
2.Check that the six transverse fixings are
tightened to a torque of 60 Nm (45 lbf.ft).

Gear Change and Parking Pawl Engagement –
(Automatic only, normal driving conditions)
1.Select 'R' and check for smooth take up.
2.Select 'D' and check for smooth up-changes of
ratio from rest.
3.Slow down vehicle and check for smooth down-
changes of ratio.
4.Stop vehicle on a slope.
5.Select 'P' and release handbrake.
6.Check that vehicle does not move and that
selector does not slip out of 'P'.
7.Carry out a similar check with vehicle facing in
the opposite direction.
Steering
1.With vehicle stationary, turn steering from lock
to lock. Check for smooth operation and ensure
there is no undue noise from the power steering
pump or drive belt.
Suspension
1.Check for noise, irregularity in ride (e.g.
dampers) and wheel imbalance.
Foot brake
1.Check for pedal effort, travel, braking
efficiency, pulling and binding.
Handbrake
1.Apply handbrake firmly, check travel and
ratchet hold and release.
Instruments
1.Check for correct operation of all instruments
and warning devices where practical.
Body
1.Check for abnormal body noise.
Seat Belts
1.Check for operation of inertia reels.Road Test
1.Drive vehicle on a short road test. Check all
vehicle systems for correct operation. Pay
particular attention to:
lEngine noise
lGearbox noise
lSuspension noise
lBody noise
lBraking system operation
lGear selection
lEngine performance
2.Where possible, check for correct operation of
Hill Descent Control (HDC) system. This should
not be carried out if excessive journey time is
required.
3.After road test, carry out a final inspection of the
vehicle on vehicle ramps.
4.Check all underbonnet fluid levels and top-up if
necessary.
