Bodywork And Underbody Condition Check; Roadwheel Bolt Tightness Check; Electrical Systems Check; Road Test - Opel Zafira B MPV 2006 Owners Workshop Manual

5 With the vehicle standing on its wheels,
the efficiency of each shock absorber may
be checked by bouncing the vehicle at each
rear corner. Generally speaking, the body will
return to its normal position and stop after
being depressed. If it rises and returns on
a rebound, the shock absorber is probably
suspect.
Note: This work should be carried out by
a
Vauxha/1/0pel dealer in order to validate
the vehicle warranty. The work includes
a
thorough inspection of the vehicle paintwork
and underbody for damage and corrosion.
Bodywork damage/
corrosion check
1 Once the car has been washed, and all tar
spots and other surface blemishes have been
cleaned off, carefully check all paintwork,
looking closely for chips or scratches. Pay
particular attention to vulnerable areas such
as the front panels (bonnet and spoiler), and
around the wheel arches. Any damage to
the paintwork must be rectified as soon as
possible, to comply with the terms of the
manufacturer's anti-corrosion warranties;
check with a Vauxhall/Opel dealer for details.
2 If a chip or light scratch is found which
is recent and still free from rust, it can be
touched-up using the appropriate touch-up
stick which can be obtained from Vauxhall/Opel
dealers. Any more serious damage, or rusted
stone chips, can be repaired as described in
Chapter 11 , but if damage or corrosion is so
severe that a panel must be renewed, seek
professional advice as soon as possible.
3 Always check that the door and ventilation
opening drain holes and pipes are completely
clear, so that water can drain out.
Corrosion protection check
4 The wax-based underbody protective
coating should be inspected annually,
preferably just prior to Winter, when the
underbody should be washed down as
thoroughly as possible without disturbing the
protective coating. Any damage to the coating
should be repaired using a suitable wax-based
sealer. If any of the body panels are disturbed
for repair or renewal, do not forget to re-apply
the coating. Wax should be injected into door
cavities, sills and box sections, to maintain
the level of protection provided by the vehicle
manufacturer - seek the advice of a Vauxhall/
Opel dealer.
1 Where applicable, remove the wheel trims
from the wheels.

2 Using a torque wrench on each wheel bolt
in turn, ensure that the bolts are tightened to
the specified torque.
3 Where applicable, refit the wheel trims
on completion, making sure they are fitted
correctly.
1 Work around the vehicle and lubricate the
hinges of the bonnet, doors and tailgate with a
light machine oil.
2 Lightly lubricate the bonnet release mech-
anism and exposed section of inner cable with
a smear of grease.
3 Check the security and operation of all
hinges, latches and locks, adjusting them
where required. Check the operation of the
central locking system.
4 Check the condition and operation of the
tailgate support struts, renewing them both if
either is leaking or no longer able to support
the tailgate securely when raised.
1 Check the operation of all the electrical
equipment, ie, lights, direction indicators,
horn, etc. Refer to the appropriate sections of
Chapter 12 for details if any of the circuits are
found to be inoperative.
2 Note that the stop-light switch is described
in Chapter 9.
3 Check all accessible wiring connectors,
harnesses and retaining clips for security, and
for signs of chafing or damage. Rectify any
faults found.
Instruments and
electrical equipment
1 Check the operation of all instruments,
warning lights and electrical equipment
2 Make sure that all instruments read correctly,
and switch on all electrical equipment in turn,
to check that it functions properly.
Steering and suspension
3 Check for any abnormalities in the steering,
suspension, handling or road 'feel'.
4 Drive the vehicle, and check that there are
no unusual vibrations or noises.
5 Check that the steering feels positive, with
no excessive 'sloppiness', or roughness,
and check for any suspension noises when
cornering and driving over bumps.
Drivetrain
6 Check the performance of the engine,
clutch, transmission and driveshafts.
7 Listen for any unusual noises from the
engine, clutch and transmission.
8 Make sure that the engine runs smoothly
when idling, and that there is no hesitation
when accelerating.
9 Check that, where applicable, the clutch
action is smooth and progressive, that the
drive is taken up smoothly, and that the pedal
travel is not excessive. Also listen for any
noises when the clutch pedal is depressed.
10 Check that all gears can be engaged
smoothly without noise, and that the gear
lever action is smooth and not abnormally
vague or 'notchy'.
11 On automatic transmission models, make
sure that all gearchanges occur smoothly,
without snatching, and without an increase in
engine speed between changes. Check that
all of the gear positions can be selected with
the vehicle at rest. If any problems are found,
they should be referred to a Vauxhall/Opel
dealer.
12 Listen for a metallic clicking sound from
the front of the vehicle, as the vehicle is driven
slowly in a circle with the steering on full-lock.
Carry out this check in both directions. If a
clicking noise is heard, this indicates wear in a
driveshaft joint (see Chapter 8).
Braking system
13 Make sure that the vehicle does not pull to
one side when braking.
14 Check that there is no vibration through
the steering when braking. Note: Under
heavy braking on models equipped with ABS,
vibration may be felt through the brake pedal.
This is
a
normal feature of ABS operation, and
does not constitute a fault.
15 Check that the handbrake operates
correctly, without excessive movement of the
lever, and that it holds the vehicle stationary
on a slope.
16 Test the operation of the brake servo unit
as follows. Depress the footbrake four or five
times to exhaust the vacuum, then start the
engine. As the engine starts, there should be a
noticeable 'give' in the brake pedal as vacuum
builds-up. Allow the engine to run for at least
two minutes, and then switch it off. If the
brake pedal is now depressed again, it should
be possible to detect a hiss from the servo as
the pedal is depressed. After about four or
five applications, no further hissing should be
heard, and the pedal should feel considerably
harder.
1 With the ignition switched off, the display
on the instrument panel must show the trip
odometer.
2 With the ignition still switched off, depress
