When driving down hills, reduce
your speed and shif t down to 2nd
gear. Do not ‘‘ride’’ the brakes, and
remember it will take longer to slow
downandstopwhentowingatrailer.
When climbing hills, closely watch
your temperature gauge. If it nears
the red (Hot) mark, turn the air
conditioning of f , reduce speed and, if
necessary, pull to the side of the
road to let the engine cool.
If the automatic transmission shif ts
f requently between 3rd and 4th
gears while going up a hill, shif t to

The added weight, length, and
height of a trailer will af f ect your car’s
handling and perf ormance, so
driving with a trailer requires some
special driving skills and techniques.

maneuvers bef ore heading f or the
open road, and f ollow the guidelines
discussed below.
Drive slower than normal in all
driving situations, and obey posted
speed limits f or vehicles with trailers.
Use the D position when towing a
trailer on level roads. D is the
proper shif t lever position to use
when towing a trailer in hilly terrain.
(See ‘‘
’’ in the next
column f or additional gear
inf ormation.) Make turns more slowly and wider
than normal. The trailer tracks a
smaller arc than your car, and it can
hit or run over something the vehicle
misses. Allow more time and
distance f or braking. Do not brake or
turn suddenly as this could cause the
trailer to jackknif e or turn over.
If youmuststopwhenfacinguphill,
use the f oot brake or parking brake.
Do not try to hold the vehicle in

as this can cause the automatic
