Wheel bolts, tightening to specified
torque
Trim cap
Puller -A- for removing the trim cap is in the vehicle tool kit.
Wheel bolts
The adapter for loosening and tightening the anti-theft wheel bolts is in the
vehicle tool kit.
Note:
Ensure that the wheel bolts are tightened diagonally and alternately to the
following tightening torque:
Tightening torque: 120 Nm (89 ft lb)
Correct installation of wheels
When installing the wheels, note the following points to ensure that the
wheels remain secure at all times: - After completing work, replace adapter in vehicle tool kit.
Always tighten the wheel bolts to the specified torque; excessive
torque can distort the wheel bolt seats in the rim.

When installing a wheel, do not torque down
the first wheel bolt immediately (for instance,
with an impact wrench). This would prevent the
other bolts from centering the wheel properly
when they are threaded in; the rim could then
come loose, even though the bolts have been
tightened to the specified torque.
Before installing the wheels, examine the seats
of the wheel bolts and the contact surfaces
between the rims and the hubs for rust and
corrosion. Clean off these parts if necesary,
otherwise this can affect the clamping force of
the bolts after installation, and the rims can
come loose.
WARNING!
If the points listed above are not observed,
the wheel mountings can come loose and the
wheel bolt seats can become distorted.
This distortion may be very slight and not
visible to the naked eye.
Even this slight distortion of the wheel bolt
seats can prevent the rims from being held
firmly and the wheels will come loose
repeatedly.

Brake pad thickness, checking
Inspection service:
Dimension -a- = pad thickness including backing plate. Wear limit = 7 mm
(0.28 in.).
Thoroughly remove all dirt from wheels.
If pad thickness including backing plate is 7 mm (0.28 in.) or less the
brake pads have reached or exceeded wear limit and must be replaced. - Determine thickness of outer and inner pads by inspecting visually.
View through opening in wheel. Use a flashlight and mirror if necessary.
- Tighten wheel bolts to 110 Nm (81 ft lb).

suspension struts. These models are
recognizable by a tag on the mirror.
- Relieve pressure on coil spring (e.g. vehicle on
lift).
Note:
It is not necessary to remove wheels.
- Pull auxiliary spring -2- down.
- Remove 2 blocking eiements -1- fitted to each suspension strut.

Note:
Try using corners of the headlight housings or
two screws that are the same height and as far
apart as possible on the vehicle.
- Carefully tighten hand wheel without changing
Beamsetter position.
- Find correct State or Province Inclination %
specification for the low beam adjustment (If
there is no local specification use 1.2%).
Note:
DO NOT use the Inclination % molded into the
plastic of the headlight housing near the
headlight adjustment screws; it is for Europe
only!
- Set Beamsetter "Scaled wheel" to the proper low
beam inclination %.
- Adjust height (vertical) alignment first. Turn
headlight height adjuster screw to align the
upper edge of the flat portion of the beam with
the center horizontal line of the grid on the
Beamsetter pattern screen.
