7A1–9
Winter Drive Mode
1.Operation
The winter switch will operate when switched on after
all of the following conditions are present:
Conditions:
a. The select lever position is “D” range only.
b. Vehicle speed is 7 mph (11 km/h) or less.
c. Transmission oil temperature is 130°C (266°F) or
less.
d. Accelerator opening is at 8% or less.
2.Cancel Release
1. Cancellation by driver
a. Turning off the winter drive mode switch
b. Shifting select position to “3”, “2”, or “L” (winter
drive mode is not canceled by selecting “N”, “R”,
or “P”).
c. Ignition key is turned off.
2. Automatic cancellation
a. When vehicle runs at 21mph (34 km/h) or more
for 1 second or more
b. When transmission oil temperature reaches
130°C (266°F) or above
NOTE: The mode returns to normal drive mode or power
drive mode after the winter drive mode is canceled.
Backup Mode
If a major system failure occurs which could affect safety
or damage the transmission under normal vehicle
operation, the diagnostic system detects the fault and
overrides the Powertrain Control Module (PCM).
The “CHECK TRANS” light flashes to alert the driver, and
the transmission must be manually shifted as follows:
Select lever position Gear Ratio Selected
D 4 (Fourth)
Manual 3 4 (Fourth)
Manual 2 3 (Third)
Manual L 1 (First)
R Reverse
Shifts are firmer to prevent clutch slip and consequent
wear. The fault should be corrected as soon as possible.
