Towing Speeds and GearsDrive slower than normal in all
driving situations, and obey posted
speed limits for vehicles with trailers.
Use the D position when towing a
trailer on level roads. D
3is the proper
shift lever position to use when
towing a trailer in hilly terrain. (See
‘‘
Driving on Hills
’’ on the next page
for additional gear information.)
When towing a fixed-sided trailer (e.
g., camper), do not exceed 55 mph
(88 km/h). At higher speeds, the
trailer may sway or affect vehicle
handling. When driving uphill and downhill,
use the Sequential SportShift mode
to provide the proper engine power
and engine braking on each gear.
Select fourth, third, second, or first
gear, depending on the vehicle
speeds and road condition. Do not
use fifth gear. The recommended
speed range for each gear position is
shown in the table.
Gear position Speed range
10 －19 mph
(0 － 30 km/h)
219 －31 mph
(30 －50 km/h)
331 －41 mph
(50 －65 km/h)
4 over 41 mph
(over 65 km/h) If the automatic transmission fluid
temperature increases and exceeds
the specified limit, the A/T
temperature indicator comes on (see
page68).You will also see a
‘‘A/T
TEMP HIGH ’’message on the multi-
information display.
Making Turns and BrakingMake turns more slowly and wider
than normal. The trailer tracks a
smaller arc than your vehicle, and it
can hit or run over something the
vehicle misses.
Allow more time and distance for
braking. Do not brake or turn
suddenly as this could cause the
trailer to jackknife or turn over.
