Making Thms
NOTICE:
Making very sharp turns while trailering could cause the trailer to come in contact with the vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
When you’re turning with a trailer, make wider turns
than normal.
Do this so your trailer won’t strike soft
shoulders, curbs, road signs, trees, or other objects.
Avoid jerky or sudden maneuvers. Signal well in
Tldvance.
’Ibrn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have a
different turn signal flasher and extra wiring. The green
arrows on your instrument panel will flash whenever
you signal a turn or lane change. Properly hooked up,
the trailer lamps will also flash, telling other drivers
you’re about to turn, change lanes or stop.
When towing a trailer, the green arrows on your
instrument panel will flash for turns even if the bulbs on
the trailer are burned out.
Thus, you may think drivers behind
you are seeing your signal when they are not. It’s
important to check occasionally to be sure the trailer
bulbs are still working.
Your vehicle has bulb warning lights. When you plug a
trailer lighting system into your vehicle’s lighting
system, its bulb warning lights may not let you know if
one of your lamps goes out.
So, when you have a trailer
lighting system plugged in, be sure to check your
vehicle and trailer lamps from time to time to be sure
they’re all working. Once you disconnect the trailer lamps, the bulb warning lights again can tell you if one
of your vehicle larnps is out.
Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade.
If you don’t shift
down, you might have to use your brakes
so much that
they would get hot and
no longer work well.
On a long uphill grade, shift down to DRIVE (@) and
reduce your speed to around 45 mph (70 kmph) to
reduce the possibility of engine and transaxle
overheating.
