SAFETY AND ENVIRONMENT PROTECTION
Warning symbols in this guide
How can you reduce the risk of personal injury and prevent possible
damage to others, your vehicle and its equipment? In this guide, answers
to such questions are contained in comments highlighted by the warning
triangle symbol. These comments should be read and observed.
Warning symbols on your vehicle
When you see this symbol, it is
imperative that you consult the
relevant section of this guide before
touching or attempting adjustment
of any kind.
Protecting the environment
We must all play our part in
protecting the environment. Correct
vehicle usage and the authorized
disposal of waste cleaning and
lubrication materials are significant
steps towards this aim. Information in this respect is highlighted in this
guide with the tree symbol.
BREAKING-IN YOUR VEHICLE
Your vehicle does not need an extensive break-in. Try not to drive
continuously at the same speed for the first 1,600 km (1,000 miles) of
new vehicle operation. Vary your speed to allow parts to adjust
themselves to other parts.
Do not add friction modifier compounds or special break-in oils during
the first few thousand kilometers (miles) of operation, since these
additives may prevent piston ring seating. See Engine oilin the
Maintenance and specifications chapter for more information on oil
usage.

6. Without turning, remove the old
bulb from the lamp assembly by
pulling it straight out of the lamp
assembly.
To install the new bulb:
Handle a halogen headlamp bulb carefully and keep out of
children’s reach. Grasp the bulb only by its plastic base and do
not touch the glass. The oil from your hand could cause the bulb to
break the next time the headlamps are operated.
Note: If the bulb is accidentally touched, it should be cleaned with
rubbing alcohol before being used.
1. With the flat side of the new bulb ’s plastic base facing upward, insert
the glass end of the bulb into the lamp assembly. Turn the bulb left or
right to align the grooves in the plastic base with the tabs in the lamp
assembly. When the grooves are aligned, push the bulb into the lamp
assembly until the plastic base contacts the rear of the lamp assembly.
2. Install the bulb retaining ring over the plastic base and lock the ring
by rotating clockwise until it snaps into place.
3. Connect the electrical connector to the bulb.
4. Install the headlamp on vehicle by aligning the lamp on the vehicle,
push rearward to fully seat the lamp assembly and install the screw on
the headlamp.
5. Push the two retainer pins down.
6. Turn the headlamps on and make sure they work properly. If the
headlamp was correctly aligned before you changed the bulb, you should
not need to align it again.
