SAFETY AND ENVIRONMENT PROTECTION
Warning symbols in this guide
How can you reduce the risk of personal injury to yourself or others? 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 1,000 miles (1,600 km) of
new vehicle operation. Vary your speed frequently in order to give the
moving parts a chance to break in.
Drive your new vehicle at least 500 miles (800 km) before towing a
trailer. For more detailed information about towing a trailer, refer to
Trailer towingin theTires, Wheels and Loadingchapter.
Do not add friction modifier compounds or special break-in oils since
these additives may prevent piston ring seating. SeeEngine oilin the
Maintenance and Specificationschapter for more information on oil
usage.
