GMC Terrain: Driving and Operating / Fuel
If equipped, LKA may help avoid
crashes due to unintentional lane
departures. It may assist by gently
turning the steering wheel if the
vehicle approaches a detected lane
marking without using a turn signal
in that direction...
Top Tier Fuel (Gasoline)
GM recommends the use of TOP
TIER Detergent Gasoline to keep
the engine clean, reduce engine
deposits, and maintain optimal
vehicle performance...
Other information:
TOP TIER Detergent Diesel is
highly recommended for use with
your vehicle. If your area does not have TOP TIER Detergent Diesel,
GM recommends the use of
ACDelco Diesel Fuel Conditioner.
This will help you maintain optimal
engine performance. GM does not
recommend other aftermarket diesel
additives...
Biodiesel is a renewable fuel
produced from vegetable oils or
animal fats that have been
chemically modified to make it
compatible with diesel fuel.
Caution
Do not use home-made biodiesel
or home test kits because the
quality cannot be verified by
approved scientific methods...
