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
During the first 1,000 miles (1,600 km) of driving, maintain speeds below
70 mph (112 km/h) and vary speeds frequently. This is recommended to
give the moving parts a chance to break-in.
Do not tow a trailer or use your vehicle to snowplow until it has been
driven at least 500 miles (800 km). Refer to Trailer towing in the Tires,
Wheels and Loading chapter for more information on towing a trailer
and Snowplowing in the Driving chapter.
Do not add friction modifier compounds or special break-in oils during
the first few thousand miles (kilometers) 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.

oil level. Add oil if needed. If the oil
level is correct, have your vehicle checked at your authorized dealer.
