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.
Drive your new vehicle at least 800 km (500 miles) before towing a
trailer.
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 oil in the
Maintenance and specifications chapter for more information on oil
usage.

or by applying the parking brake when the ignition is turned to the ON
position. If the brake system warning light does not illuminate at this
time, seek service immediately from your dealership. Illumination after
releasing the parking brake indicates low brake fluid level and the brake
system should be inspected immediately by your servicing dealership.
Driving a vehicle with the brake system warning light on is
dangerous. A significant decrease in braking performance may
occur. It will take you longer to stop the vehicle. Have the vehicle
checked by your dealer immediately.
Anti-lock brake system: If the
ABS light stays illuminated or
continues to flash, a malfunction has
been detected, have the system
serviced immediately. Normal
braking is still functional unless the brake warning light also is
illuminated.
Air bag readiness: If this light fails
to illuminate when ignition is turned
to ON, continues to flash or remains
on, have the system serviced
immediately. A chime will also sound when a malfunction in the
supplemental restraint system has been detected.
Safety belt: Reminds you to fasten
your safety belt. A chime will also
sound to remind you to fasten your
safety belt.
Charging system: Illuminates when
the battery is not charging properly.
Engine oil pressure: Illuminates
when the oil pressure falls below the
normal range. Refer to Engine oil
in the Maintenance and
Specifications chapter. ABS
