STARTING AND DRIVING

CAUTION
•
When starting in cold weather, the auto-
matic transmission may shift up at slightly
higher engine speeds than normal until
the automatic transmission fluid reaches
normal operating temperature.
•
Do not race a cold engine immediately
after starting. Oil flow may not reach
some lubrication points fast enough to
prevent engine damage.
•
The engine should be idling when you
move the gear selector. Never accelerate
until after you feel the transmission
engage. Accelerating immediately after
selecting a gear will cause harsh engage-
ment and premature transmission wear.
•
Selecting
P
or
N
when idling at a stand-
still for prolonged periods of time will help
prevent overheating of the automatic
transmission fluid.

Driving systems
The XC90 T8 Twin Engine Plug-in Hybrid is a
parallel hybrid, which means that it has two sep-
arate drive systems: an electric motor and a gas-
oline engine. Depending on the drive mode
selected and the amount of electric power avail-
able in the hybrid battery, the two systems can
be used in tandem or separately.

A control system coordinates both of the drive
systems to help optimize driving economy.
