Fuels in Fo ign Countries
--
Gasoline
Engines
If you plan on driving in another country outside the
United States or Canada, the proper fuel may be hard to
find. Never use leaded gasoline or any other fuel not
recommended in the previous text on fuel. Costly repairs
caused by use of improper fuel wouldn't be covered by
your warranty.
To check on fuel availability, ask an auto club, or
contact a major oil company that does business in the
country where you'll be driving.
You can also write us at the following address for
advice. Just tell us where you're going and give your
Vehicle Identification Number (VIN).

Filling Your Tank
The fuel cap is behind a
hinged door on the left side
of your vehicle.
On a chassis-cab model, refuel the front tank first, or in
instances when only a partial fuel fill is desired.
