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. Additionally, during the first 500 miles (800 km) that you tow a
trailer, do not drive over 70 mph (112 km/h) and do not make starts at
full throttle. This style of driving will help the engine and other parts of
your vehicle break in at the heavier loads. For more detailed information
about towing a trailer, refer to
Trailer towing
in the
Tires, Wheels and
Loading
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.
