WARNING
Adequate size trailer brakes are required when the trailer and
its cargo exceed 1,000 lbs (453 kg) total weight. Do not directly connect your trailer ’s hydraulic brake system
to the hydraulic brake system in your vehicle. Direct connectionwould cause the vehicle ’s brake performance to deteriorate and
could lead to an accident.
If your trailer ’s total weig ht (trailer weig ht p lus its c arg o weig h t)
exc eed s 1,000 lb s (453 kg ), the trailer is req uired to b e eq uip p ed with
its own b rake system. Elec tric b rakes or surg e b rak es are rec om-
mend ed , and must b e installed p rop erly. Chec k that your trailer’s
b rakes c onform with Fed eral, state/p rovinc e and /or other ap p lic ab le
reg ulations. Your SUBARU ’s b rake system is not d esig ned to b e
tap p ed into the trailer ’s hyd raulic b rake system. Please ask your
SUBARU d ealer and p rofessional trailer sup p lier for more information
ab out the trailer ’s b rake system.
n Trailer safety chain
WARNING
Always use safety chains between your vehicle and the trailer.
Towing trailer without safety chains could create a traffic safetyhazard if the trailer separates from the hitch due to coupling dam-age or hitch ball damage.
In c ase the trailer hitc h c onnec tor or hitc h b all s hould b reak or
b ec ome d isc onnec ted , the trailer c ould g et loose an d c reate a traffic
safety hazard .
For safety, always c onnec t the towing vehic le and t railer with trailer
safety c hains. Pass the c hains c rossing eac h other und er the trailer
tong ue to p revent the trailer from d rop p ing onto th e g round in c ase
the trailer tong ue should d isc onnec t from the hitc h b all. Allow suffi-

Trailer towing tips CAUTION
Never exceed 45 mph (72 km/h) when towing a trailer in hilly
country on hot days. When towing a trailer, steering, stability, stopping distance and
braking performance will be different from normal operation. For
safety’ s sake, you should employ extra caution when towing a
trailer and you should never speed. You should also keep the fol-lowing tips in mind:
n Before starting out on a trip
Chec k that the vehic le and vehic le-to-hitc h mountin g are in g ood
c ond ition. If any p rob lems are ap p arent, d o not tow the trailer.
Chec k that the vehic le sits horizontally with the t railer attac hed . If
the vehic le is tip p ed sharp ly up at the front and d own at the rear,
c hec k the total trailer weig ht, GVW, GAWs and tong u e load ag ain,
then c onfirm that the load and its d istrib ution are ac c ep tab le.
Chec k that the tire p ressures are c orrec t.
Chec k that the vehic le and trailer are c onnec ted p r op erly. Confirm that
– the trailer tong ue is c onnec ted p rop erly to the hit c h b all.
– the trailer lig hts c onnec tor is c onnec ted p rop erly and trailer’s
b rake lig hts illuminate when the vehic le ’s b rake p ed al is p ressed ,
and that the trailer ’s turn sig nal lig hts flash when the vehic le ’s turn

– all c arg o in the trailer is sec ured safety in p osit ion.
– the sid e mirrors p rovid e a g ood rearward field of v iew without a
sig nific ant b lind sp ot.
Suffic ient time should b e taken to learn the “feel ” of the vehic le/
trailer c omb ination b efore starting out on a trip . In an area free of traf-
fic , p rac tic e turning , stop p ing and b ac king up . n Driving with a trailer
You should allow for c onsid erab ly more stop p ing d is tanc e when
towing a trailer. Avoid sud d en b raking b ec ause it m ay result in skid -
d ing or jac kknifing and loss of c ontrol. Avoid ab rup t starts and sud d en ac c elerations. If yo ur vehic le has a
manual transmission, always start out in first g ear and release the
c lutc h at mod erate eng ine RPM. Avoid uneven steering , sharp turns and rap id lane c hang es.
Slow d own b efore turning . Make a long er than normal turning
rad ius b ec ause the trailer wheels will b e c loser th an the vehic le
wheels to the insid e of the turn. In a tig ht turn, the trailer c ould hit your
vehic le. Crosswind s will ad versely affec t the hand ling of yo ur vehic le and
trailer, c ausing sway. Crosswind s c an b e d ue to wea ther c ond itions or
the p assing of larg e truc ks or b uses. If swaying oc c urs, firmly g rip the
steering wheel and slow d own immed iately b ut g rad ua lly.
When p assing other vehic les, c onsid erab le d istanc e is req uired
b ec ause of the ad d ed weig ht and leng th c aused b y at tac hing the
trailer to your vehic le. When b ac king up with a trailer, never ac c elerate or steer rap id ly.
When turning b ac k, g rip the b ottom of the steering wheel with one
hand and turn it to the left for a left turn, and t urn it to the rig ht for a
rig ht turn.

If the ABS warning lig ht illuminates while the vehi c le is in motion,
stop towing the trailer and have rep airs p erformed immed iately b y the
nearest SUBARU d ealer. n Driving on grades
Before g oing d own a steep hill, slow d own and shift into low g ear
in ord er to utilize the eng ine b raking effec t and p revent overheating of
your vehic le ’s b rakes. Do not make sud d en d ownshifts.
When d riving up hill in hot weather, the air c ond iti oner may turn off
automatic ally to p rotec t the eng ine from overheatin g .
When d riving up hill in hot weather, p ay attention t o the water tem-
p erature g aug e need le (for all vehic les) and ATF OI L TEMP warning
lig ht (for AT vehic les) sinc e the eng ine and transm ission are relatively
p rone to overheating und er these c ond itions. If the water temp erature
g aug e need le ap p roac hes the OVERHEAT zone or the AT F OIL TEMP
warning lig ht illuminates, immed iately switc h off t he air c ond itioner
and stop the vehic le at the nearest safe p lac e. Ref er to “Eng ine over-
heat ” sec tion (c hap ter 8), and “Warning and ind ic ator lig hts ” sec tion
(c hap ter 3) in the owner ’s manual.
If your vehic le has a automatic transmission, avoid using the ac c el-
erator p ed al to stay stationary on an up hill slop e instead of using the
p arking b rake or foot b rake. That may c ause the tra nsmission fluid to
overheat. Also, if your vehic le is eq uip p ed with an automatic transmis-
sion, avoid d riving with the g ear selec tor lever in “ D ” when towing a
heavy trailer to p revent fluid overheating .

SAE viscosity number and applicable temperature
Recommended grade and viscosity under severe driving conditions
If the vehic le is used in d esert areas, in areas wi th very hig h temp era-
tures, or used for heavy-d uty ap p lic ations suc h as a towing a trailer,
use of oil with the following g rad e and visc osities is rec ommend ed .
API classification SJ or SH:
SAE viscosity No.: 30, 40, 10W-50, 20W-40, 20W-50

10-40c ations. Chec k the tire p ressure when the tires are
c old . Cold means that
the vehic le has b een p arked for three hours or has b een d riven less than
1 mile (1.6 km).
HS0251
The rec ommend ed tire p ressure and sizes are p rovid e d on the tire p lac -
ard , whic h is loc ated und er the d oor latc h on the d river’s sid e.
Adjusting the tire pressure
The tire p lac ard shows the rec ommend ed tire p ressur es at lig ht load ,
at full load and when towing a trailer. If the vehi c le is load ed with three
oc c up ants or less, ad just the tire p ressure to the level rec ommend ed
for lig ht load . If the vehic le is more load ed , ad ju st it to the level rec om-
mend ed for full load . When towing a trailer, ad just it to the level rec -
ommend ed for that op eration.
Tire rotation
Tire wear will vary with eac h wheel. To inc rease th e life of tires and keep
wear uniform, it is b est to rotate them every 7,500 miles (12,500 km).
When rotating tires, rep lac e any unevenly worn or d amag ed tire. After
rotating the tires, ad just tire p ressure and b e sur e to c hec k wheel nut
tig htness.
